Improvements in oz relating to Means of Attaichment of' Two' Parts

Together' in a Detachable Manner.

We, PHILIPS ELECTRICAL INDUSTRIES LIMITED, Spencer House, South Place,

Finsbury, Lohdon, E C 2, a British Company, do hereby declare tie

invention, for which we pray that a patent may be granted to us, and

the method by which it is to be performed, to be particularly

described in and by the following statement:-

The invention relates to iieans for attaching two parts to one another

in a detachable manner It is an object of the invention to provide a

cheap and practical attaching means which is particularly suitable for

attaching a radio receiver to the instrument panel of an automobile.

According to the invention the means comprises a strap made from

strip-material shaped into the form of a vertically arranged U having

very short limbs which are secured to one of the parts to be joined to

one another, two slits being formed so as to be parallel to one

another in the horizontal portion of the strap adjacent the limbs,

each of which slits comprises a narrow middle portion and two widened

end portions of unequal width and co-operates with a pin, screw or the

like, secured vertically on the other part which is required to be

attached, each pin, screw or the like comprising a head which fits

within the widest portion of the slit, a shank which fits within the

narrowest portion and a shoulder provided at the underside of the head

which fits within the remainder of the slit and is situated therein in

the normal position of the parts when attached to each other, whilst

the middle part of the horizontal portion of the strap resiliently

engages the part required to be attached on which the pins, screws or

the like are provided and locks the pins, screws or the like against

displacement in the slits.

It should be noted that the system of slits and pins, screws or the

like used is known per se, for example, for securing curtains.

The invention will now be described more fully with reference to the

accompanying drawlPrice 3 s 6 d l ing, in which: 45 Figures 1 -and 2

are a fiont-view and a sideview respectively of one embodinient used

to secure an autotn 6 bile radio receiver, and Figures 3 and 4 show

details of this embodiment o 50 Figures 1 and 2 show-the attachment of

the front side of an automobile radio receiver 1 to a horizontal

supporting: flange of a wall 3, in the present case a flange of -the

instrument panel 5 of an automobile The supporting 55 member comprises

a strap 7 made of stripmaterial, for example, steel strip, shaped into

the form of a vertical U having very short limbs which are secured to

the supporting wall 3, for example by means of screws 60 Adjacent the

limbs of the U two parallel slits are provided at right angles to the

direction of length of the horizontal portion of the U-shaped strap 7,

one of which is shown in Figure 3 The slit comprises a narrow middle

65 portion 9 and two widened preferably circular end portions 11 and

13 of unequal diameter.

Each slit co-operates with a pin, screw or the like (Figure 4) secured

vertically in the receiver case and having a head 15 which fits with a

70 small amount of clearance in the portion 13 of the slit, a shank 17

which fits in the narrowest portion 9 and a shoulder 19 which is

provided underneath the head 15 and fits into the portion 11 75 When

the receiver 1 is to be secured to the strap 7, the head 15 of each

pin, screw or the like is inserted from below into the portion 13 of

the associated slit through a distance such that the shoulder 19 is

situated above the level 80 of the base of the U-shaped strap 7 When

the receiver 1 is moved to the front, the shank 17 passing through the

narrow portion 9 of the slit, and subsequently is lowered, the heads

15 will bear upon the strap 7 at the point of the 85 slit portions 11

the diameter of which is smaller than that of the heads The shoulders

19 of the pins, screws, or the like are arranged in the slit portions

11; they cannot be removed therefrom by mere shifting without previous

raising, since the diameter of the shoulders 19 exceeds the width of

the slit portion 9.

Thus, unintentional raising of the receiver and the pins, screws or

the like, for example, due to shocks when the automobile is running,

is prevented, since the centre part of the horizontal middle portion

of the strap 7 (the base of the U) resiliently engages the receiver 1

and presses it down The middle portion of the strap 7 may for this

purpose be slightly bent (Figure 1) or may engage a projection (not

shown) provided on the top of the case of the receiver 1.

The receiver 1 is readily detachable by raising it against the

pressure of the strap 7, moving it back and lowering it.

On the rear side of the receiver 1 a second securing means of the kind

described may be provided However, a simple hooked brace 21 which

supports the receiver will be sufficient since the attachment at the

front prevents any displacement If required, however, the receiver can

be secured to the brace 21 with a few readily accessible screws 23.

Improvements in or relating to Apparatus-for Measuring, Checking or

Dispensing Various Products such as, for Example, Fuels.

We,; G PAN Do ZY & FIGLI S r L, an Italian Body Corporate 11, Via

Vivaio, Milan, Italy, do hereby declare the invention, for which we

pray that a patent may be granted to us, and the method by which it is

to be performed, to be particularly described in and by the following

statement: -

The present invention relates to apparatus for measuring, checking or

dispensing various products, such as, for example, apparatus for

dispensing fuels, energy and the like, and automatic weighing machines

or the like, which apparatus are already provided with devices adapted

to check the quantities measured or I 5 delivered and/or adapted to

compute the respective price of the measured or delivered product.

It is a particular object of the invention to provide an additional

machine which is applicable to the apparatus specified above, said

machine being adapted to print and issue a cash register ticket and

being moreover combined with a safety device permitting the use of

said machine and/or the drawing of the products from said apparatus

exclusively to authorised persons, even if in considerable number.

According to this invention there is provided for application to

apparatus for measuring, checking or distributing- various products'

such as, for example, fuels, a machine for printing and issuing cash

register tickets or slips in combination with a safety device, such

'machine being provided with devices for recording the capacity and/or

the respective price of the product measured, checked or delivered,

and comprising numbering printing members connected kinematically with

the automatic computing or counting device of the apparatus, a safety

device actuating means adapted to unlock the apparatus and to permit

the use of the machine and means adapted to cause the printing and

issuing of the ticket, the clearing of the numbering printing members

and the locking lPrice 3 s 6 d l of the apparatus-and of the machine

at the end 45 of the operation.

The niumbering printing members are preferably arranged along one

single axis and their control and clearing carried out concentrically

'50 Connection with the 'computing device existing in the' apparatus

takes place, for example, by means of toothed gearing Of the set -of

numbering members which compose a figure, e g to indicate the quantity

of product 55 measured or'delivered or to indicate the respective

price, the existing computing-device controls only the first member,

which in turn controls by means of planetary gears in a manner known

per se the other members 60 belonging to the same figure, those

members being irreversible.

The safety device is constituted preferably by a lock that can be

operated by means of distinctive keys by a certain number of

authorised 65 persons The means co-operating with and controlled by

said lock ensure that the operation of the whole delivering,

measuring, etc apparatus for the products is only possible when there

has been previously introduced 70 said key which then remains locked

in the machine for the complete cycle of operation and is not

recoverable except at the end thereof.

The means which cause the printing and the 75 issuing of the cash

register ticket, the clearing of the numbering printing members and

the locking of the apparatus with the contemporaneous release of said

key may be operable by hand, e g by means of a crank 80 handle, or by

any servomechanism and they are formed essentially of a toothed

gearing with cams and levers.

In addition to the printing and issuing of a ticket in the machine

according to the inven 85 tion there can also be printed a statistical

or checking sheet or tape and moreover it is possible also to stamp

interesting -data on cards, papers; etc Such data may be, for

instance, the distinctive symbol of the person that has carried out

the operation (number or sign corresponding to a specific key), the

quantity of product delivered or checked, the amount in currency of

the quantity delivered or checked, the progressive number of the

operation, the distinctive number of the machine; moreover there may

be recorded the date at which the operation was carried out, the trade

mark of the product andlor of the firm, as well as advertising or

indicative scripts To form the distinctive number of the person that

has carried out the operation, the safety lock and every key may be

provided with mechanisms adapted to act during the opera-tion of

unlocking the machine, upon stamping members ciphered with distinctive

symbols or numerals which permit all of the combinations corresponding

to those of each key.

Numbering sectors form -and print the progressive number of each

operation while special external knobs connected to numbered printing

sectors permit the daily forming of the date.

For the printing of the brand or trade-mark, and of the advertising or

indicative scripts, there are provided printing members equipped with

special printing blocks or plates.

The machine is then completed with all members needed for printing,

for advancing the paper tape for the ticket or slip, for advancing and

reeling the paper tape for the checking sheet, for advancing, reeling

and automatic reversing of the copying ribbon and for cutting the

ticket or slip from the respective paper tape.

Moreover, there may be provided devices for locking the apparatus in

case of exhaustion of the supply of paper for the ticket and of paper

for the control sheet.

To make the invention more fully clear, there will be described

hereinafter merely by way of example and without limitation one

embodiment of the machine as applied to a common fuel dispenser (e g a

gasoline or petrol pump) In the following description, reference will

be made to the accompanying drawings in which: FIGURE 1 shows

diagrammatically the gasoline or petrol pump to which the machine

according to the invention is applied; FIGURE 2 illustrates the

connection between the subject machine and the automatic computer of

Referring to Figure 1, it will be seen that the machine according to

this invention is applied, in the case chosen as an example, to a

conven 85 tional gasoline or petrol pump (fuel dispenser) 1, which is

provided with a delivery tube or gun 2 having an actuating button 3

and hooked to a supporting fork 4 A breaker 5 (Figure 5) which is

actuated on the lifting of the fork 4 90 when the gun 2 is removed

therefrom, starts the motor and the delivery pump proper (which are

not shown in the drawing) and the fuel is delivered on pressing the

button 3 Moreover, the dispenser is provided with both an auto 95

matic computer 6 of the quantity of fuel delivered and an automatic

computer 7 of the amount in currency belonging to, said quantity.

Those computers 6 and 7 are of known kind, being readable from the

exterior of the pump, 100 and are operated by means of the rotation of

the first gear and a known planetary system, the two computers being

cleared by making two revolutions of a crank-handle 8.

The machine according to this invention is 105 contained in a casing 9

so that it can be easily applied, e g to a gasoline or petrol pump as

hereinbefore stated All the parts composing the machine are supported

between two side panels 10 and 11 of the casing 9 110 Rigidly fixed to

the wall 10 of the casing 9 are three columns 12, 13 and 14 carrying

two plates 16 and 17 spaced from each other and from a front plate 15

fixed to, the columns 12, 13 and 14 by means of bolts 12 a, 13 a and

14 a 115 having threaded nuts thereon, the framing so formed serving

to support the numbering printing members, together with respective

accessory members, and also to support the safety lock 120 The

numbering printing members are constituted by two coaxially arranged

sets of numbering discs 18 and 19 (see Figures 7 and 8), of which the

one set of discs 18 serves to stamp the figure indicating the quantity

of fuel 125 delivered, whilst the other set of discs 19 serves to

stamp the figure indicating the respective amount in currency On the

same axis of the discs 18 and 19 there are also provided other

numbered discs 20 for composing and 130 785,776 1 spective serrated

wheels 32, 34.

The clearing device for the numbered discs 18, 19 is connected to that

clearing device controlled by the crank-handle 8 and provided in the

dispenser 1 70 To the end of the shaft 49 (Figure 2) carrying the

crank-handle 8 there is fixed a pinion which meshes with a -toothed

wheel 51 on a shaft on which there are also fixed toothed wheels 52

having semi-circular toothing 75 which meshes with toothed wheels 53,

54 fitted respectively to the ends of the shafts 28 and 30 projecting

from the wall 10 Shafts 28 and 30, which are coaxial with-the shafts

27 and 29, are arranged -respectively around-the shaft 27 80.

and around-the shaft 29 and each have an intermediate -flange 55 and

56 The discs 18 are mounted in a freely rotatable manner around the

terminal portion of the shaft 30 and between its flange 55 and the

serrated wheel 34, 85 whilst the discs 19 are arranged around the

terminal portion;of the shaft 28 between its flange 56 and the

serrated wheel 32 The shafts 28 and 30 have in their terminal portions

external longitudinal grooves 57, 58 re 90 spectively in -which the

pawls 59 pivoted on each of said discs can engage for the purpose of

clearing the discs 18 and 19 The pawls 59 are kept in contact with

pipes 28 and 30 by flat springs 60 (see Figure 11), and the flanges 95

and 56 of the shafts 28 and 30 are each provided with a peripheral

notch 61 (Figure-10).

Two frames, 62, 63 support' the planet wheels 47 and each has a

wedge-shaped projection 64 adapted to engage in the respective 100

notch 61 of the flanges 55 and 56 A spring 65 for each frame 62 and 63

acts in a sense to keep the wedge-shaped projections 64 engaged in the

respective notches 61 ini which position the planet wheels 47 also

mesh -with the discs 105 18 and 19 respectively The planet wheels 47

when disengaged from the respective discs 18 and 19-are held in

meshing position by means of elastic plates 66, whilst other elastic

plates 67 brake the discs 18 and 19 110 The shaft 30 carries, in the

proximity of its flange 55, a toothed wheel 68 which meshes with a

toothed wheel 69 fitted on a shaft 70 supported rotatably in the

frames 62 and 63.

At the other end of the shaft 70 (see Figures 7 115 and 13) there is

fixed a toothed wheel 71 which actuates the disc 20 ' adapted to

control by means of planet wheels 72 the numbered discs 20 forming the

progressive number A complete rotation of the shaft 30 determines 120

the advancement of the progressive number by one unit.

As clearly shown in Figure 8, the discs 20 are arranged to be freely

rotatable about the hollow body 33 rigid with the supporting plate 125

17 and are aligned with the discs 18 and 19.

Between the numbered discs 20 and the front plate 15 there are further

provided two discs 21 which too are aligned with the discs 18 and 19 '

130 stamping the progressive number of the operations, and, finally,

discs 21 provided with numerals and signs for composing and stamping

the distinctive sign of the person who has carried out the dispensing

operation.

In addition, a printing block or plate 22 carrying the distinctive

number of the machine is fixed in a suitable position on the plate 16.

In staggered relationship with respect to the axis of the discs 18,

19, 20 and 21, there are provided printing sectors 23 connected to

appropriate knobs 24 externally of the plate 15 ' for the composing

and printing of the date.

Moreover, on the frame formed on' the columns 12, 13 and 14 there are

fixed printing members provided with special printing blocks or plates

25 for printing fixed and advertisement inscriptions (see Figure 4).

The numbering printing members constituted by the discs 18 and 19 are

arranged respectively between the wall 10 and the plate 16 (the set of

discs 18) and between the plates 16 and 17 (the set of discs 19).

The wall 10 has internally a supporting flange 26 with a through hole

wherein there are supported rotatable with respect to one another four

concentric shafts 27, 28, 29 and 30, of which the internal shafts 27

and 28 pass through a hole 31 in the plate 16, and extend towards the

supporting plate 17, whilst the shafts 29 and 30 end in the proximity

of the plate 16 To one end of the internal pipe 27 there is' rigidly

fixed a serrated wheel 32 having peripheral and front toothing, the

front portion of the wheel 32 being guided and supported in a bore of

the body 33 rigid with the plate 17 The intermediate shaft '29 is

terminated before the plate 16 and also has fixed thereon a serrated

wheel 34 having exclusively peripheral toothing At their opposite and

outer ends the shafts 27 and 29 are terminated with toothed wheels 35

and 36 fitted to the respective shafts outside the wall-10 of the

-casing 9.

4 S As shown clearly in Figure 2, the toothed wheels 35 and' 36 are in

direct engagement with unit ratio with the toothed wheels 37 and 38

respectively fitted on the concentric shafts 39 and 40 To the opposed

ends of these shafts 39 and 40 are rigidly fixed the toothed wheels 41

and 42 respectively meshing with the toothed wheels 43 and 44 of the

automatic computers 6 and 7 provided in the dispenser 1.

Through this gearing connection the movements of the computers 6 and 7

are transmitted the serrated wheels 32 and 34 (Figure 8) which, by

means of pawls 45 and 46 'respectively pivoted to the first discs of

the two sets of numbered discs 18 and 19 (see Figure 12), transmit the

movements to those first discs of the printing computing groups

The'transmission to the other discs of said groups is effected in a

manner known per se by means of planetary gears 47 (Figure 11) Elastic

tongues ' 48 keep the pawls 45,46 engaged with the re785,776 3 Those

discs 21 'form part of the safety lock and serve to print the

distinctive number corresponding to the key used as will hereinafter

be described.

The safety lock comprises a guide member 73 for a key 74 and fixed

externally to the front plate 15, this guide member 73 having a slot

75 in communication with an analogous slot in the plate 15

corresponding to the external profile of the key -The terminal portion

of the key 74 is cylindrical and hollow and has an external

longitudinal groove 77 which opens into-another circular groove 78.

The key is provided at its end with two diametrically opposed vanes 79

and 80 which have their inner ends projecting into the bore of the

key, the vane 79 being provided with a step 81 determining a certain

distance in respect to the centre of the key and different for each

individual key The discs 21 have internally a stepped profile 82 with

which the step 81 of the vane 79 co-operates during the rotation of

the key A peg 76 provided in the slot 75 of the member 73 slides,

during the introduction and rotation of the key, in-the grooves 77 and

78 respectively and as a consequence thereof the key has to be

completely introduced before it be possible to rotate it Further, the

extraction of the key is possible only in one determined angular

position thereof.

Inside the body 33 which is rigid with the supporting plate 17 there

is provided a small cylinder 83 having a helical slot 84 in its

peri'phery, this slot 84 engaging a peg 85 rigid with the body 33 in

such a way that the small cylinder 83 in rotating about its axis also

performs a longitudinal displacement The small cylinder 83 carries an

axial extension 86 provided with special grooves wherein there can

engage the internal ends of the vanes 79 and of the key 74 (Figure 8)

In the direction opposite to the extension 86, the small cylinder 83

is rigid with a rod 87 slidable in the shaft 27 and having its end 88

projecting from the other side of this shaft.

Inside the body 33 there is also provided a shaped plate 89 which has

at one end a wedgeshaped formation co-operating with the front

toothing of the wheel 32 (see Figures 8 and 9) and at its other end

projects into the internal hollow of discs 21 into which the vanes 79

and of the key 74 pass when the latter is introduced into the lock and

is rotated.

An upper projecting portion of the plate 89 is adapted to co-operate

with a cylindrical cam having an inclined plane 90, rigid internally

with the disc 20 ' The plate 89 is in an inclined plane with respect

to the plane of introduction of the vanes 79 and 80 of the key (see

Figure 13) to render it inaccessible from outside The end 88 of the

rod 87 serves as a means for locking the members controlling the

delivery of fuel and co-operates with a crank lever 91 (Figures 4 and

5) pivoted at 92 on the wall of the dispenser One arm of the lever 91

is connected with both the control lever of the breaker 5 and the

supporting fork 4 This latter connection is effected by means of a

gauged spring 93 which prevents the forced 70 actuation of the breaker

5 when the lever 91 is locked, that is, when the end 88 of the rod 87

is engaged in a special bore 94 of the lever 91.

The lever 91 is provided with a tail 95 for covering the aperture

through which the rod 75 87 is retracted in the shaft 27, while it is

so retracted, and the lever 91 is displaced angularly about

its'fulcrum 92.

The machine according to the invention is further provided with

mechanisms for printing 80 the ticket or slip and a control sheet.

Figure 6 shows a roll 96 from which paper tape 97 for the cash

register tickets to be printed unreels The paper tape 97 passes under

the printing members and is guided by 85 special rolls and above said

printing members passes a second paper tape 98 unreeling from a roll

99 and reeling up on a roll 100.

This second paper tape 98 serves as a record for the operations

carried out and remains in 90 the machine Since the same data are

printed on both tapes 97 and 98, the printing members carry equal

digits in diametrically opposed positions It will be understood that

on the record tape 98 there are printed only the data 95 which

interest for the purpose of checking, while the other data such as for

instance the date, advertising texts and the like, are printed

exclusively on the lower paper tape 97 A copying ribbon 101 passes

both upside and 100 downside between the printing members and the

respective paper tapes.

The stamping of the two paper tapes 97 and 98 is determined by hammers

105, 106 and 107 arranged at the ends of levers which receive a 105

percussion movement from a lever 108 in such a way as to bring said

beaters under pressure against the printing members numbered, viz.

provided with signs or words The paper tape 97 passes through a shear

109 which is 110 actuated by a connecting rod 110 connected to a lever

111.

The members which control the beaters for stamping, which advance the

paper tapes and the copying ribbon and which actuate the 115 shear,

are the following:

The pinion 50 fixed on the shaft 49 of the crank-handle 8 (see Figure

2) meshes not only with the toothed wheel 51 but also with a toothed

wheel 112 fitted on a shaft 113 which 120 carries inside the casing 9

a toothed wheel 114.

This wheel 114 meshes with the three toothed wheels 115, 116 and 117

(Figure 6) To the shaft of the wheel 115 there is fixed a cam 118 with

which the end of the lever 108, which 125 controls the hammers 105,

106 and 107, is kept in contact by means of a spring 119 Moreover the

wheel 115 has a guide groove 120 in which there is guided a pin 121

rigid with the end of a lever 104 which carries members 102 130

785,776 ' is rendered unextractable When the delivery of the desired

quantity has been attained, the button 3 is released and the pipe 2 is

hooked on the fork 4 determining the stopping of the motor and,

therefore, of the pump In order to 70 be able to recover the key, it

is necessary now to clear the computing devices with the aid of the

crank-handle 8 During this operation the devices of the machine act in

the following manner The rotation of the crank-handle 75 determines

the rotation of the toothed wheels 52 and 114 During a first period

the toothed wheels 52 do not mesh with the wheels 53, 54, the toothing

of the wheels 52 being extended only over half their circumference The

wheel 80 114 causes rotation of the wheels 115, 116 and 117 and the

cam 118 immediately releases the lever 108 (Figure 6 illustrates the

position at the beginning of the movement) which under the action of

the spring 119 determines a move 85 ment of percussion of the beaters

105, 106 and 107 and, thereby, the contemporaneous stamping of all of

the appropriate data, at one side on the paper tape 97 and on the

other side on the paper tape 98 After stamping, the lever 124 90 goes

down owing to the rotation of the guide groove 122, and causes the

toothed wheel 125 to mesh with the toothed wheel 127 which is already

in movement In that way, the two rolls 126 and 128 drag forward the

tape 97 by 95 an amount determining the length of the ticket or slip

The lever 124 is then automatically raised again and the tape 97 stops

again, ready for a subsequent stamping operation 100 Contemporaneously

with this operation, the lever 104 also lowers by the effect of the

rotation of the guide groove 120 and the members 102 and 103 advance

the copying ribbon 101 and the paper tape 98 by the neces 1615 sary

amount Consequently, the toothing of the wheel 52 meshes with the

wheels 53 and 54 and determines a rotation of the shafts 28 and

(Figure 8) The wedge-shaped projections 64 of the frames 62 and 63

leave the respec 110 tive notches 61 of the flanges 55 and 56 (Figure

10) in such a manner as to disengage the planet wheels 47 from the

discs 18 and 19 and the small elastic plates 67 brake all the discs 18

and 19 115 The longitudinal grooves 57, 58 of the shafts 28 and 30

meet in their rotation progressively the pawls 59 of the discs 18 and

19, taking these to zero position (see Figure 11).

At the same time, the toothed wheel 68 120 rigid with the shaft 30

rotates the shaft 70 and actuates, by means of the wheel 71 the disc

20 ' of the computer of the progressive number, thereby determining an

advancement by one unit or increment The disc 20 ' with its cam 125

having an inclined plane 90, acts upon the upper portion of the small

plate 89 and makes it indent with its wedge-shaped end in a spaceof

the front toothing of the wheel 32 In this way the key 74 is again

free and recoverable, 130 and 103 adapted to cause the advancement by

the necessary amount of the copying ribbon 101 and of the paper tape

98 respectively.

The wheel 114 also has a guide groove 122 for a pin 123 rigid with the

end of a lever 124 which at its other end carries a freely rotatable

toothed wheel, 125 and a roll 126 When the lever 124 is lowered, the

wheel 125 can mesh with a wheel 127 actuated by the wheel 116 which in

turn meshes with the wheel 114 On the axis of the wheel 127 there is

fixed a circumferentially grooved roll 128 which, together with the

roll 126, causes advancement of the paper tape 97 passing between said

two rolls Further, the wheel 117 has a guide groove 129 for a pin 130

rigid with the lever 111 for controlling the shear 109.

Operation of the machine described above is as follows:

At the beginning of each fuel delivery operation, it is necessary to

unlock the dispenser and the machine by introducing into the safety

lock a special key 74 When the key is introduced completely, the

internal ends of its vanes 79 and 80 are engaged in the grooves of the

extension 86 of the small cylinder 83.

On turning the key clockwise through 180 , the small cylinder 83 is

rotated and, at the same time, displaced longitudinally in the

direction of the arrow in Figure 8 By this displacement, the rod 87

which is rigid with the small cylinder 83 is retracted into the shaft

27 and the lever 91 is released.

At the same time, the vane 79 of the key determines a rotation by a

certain angle of the discs 21 The angle of rotation of said discs

depends on the point at which the step 81 of the vane 79 meets the

stepped profile 82 of said discs and said angle varies in accordance

with different keys In this way distinctive symbols corresponding to

the particular key with which the operation is carried out are

prepared for subsequent stamping.

On lifting of the delivery tube 2, the fork 4 acts, by means of the

traction exerted by a spring 131, upon the gauged spring 93, which in

turn exerts a pressure upon the lever 91 unlocked in such a way as to

actuate the breaker which starts the motor and the delivery pump

Delivery begins when the button 3 on the pipe 2 is depressed; and with

the delivery of the fuel the counting devices 6 and 7 of the dispenser

are automatically actuated These in turn actuate through the

connection described, the numbering printing discs 18 and 19 of the

machine of the invention.

With the rotation of the wheel 32, the wedge-shaped end of the shaped

plate 89, which was previously housed inl a space of the front

toothing of the wheel 32, is pushed out of this space in such a way

that the plate 89 is displaced so that its other end projects into the

interior of the discs 21 and creates a hindrance for the lower vane 80

of the key which is turned upwards In this way the key 785,776 viz

extractable During this clearing operation, the shafts 27 and 29 are

at rest and the pawls 45, 46 friction along the toothing of the

respective serrated wheels 32 and 34 At the same time, the guide

groove 129 (Figure 6) lowers in its rotation the lever 111, thereby

actuating the shear 109 in such a way as to detach the printed ticket

from the tape 97.

At this time the operation is finished and the operator can carry out

a new operation or lock the machine and the delivery device, and

recover his key In this latter case he turns the key by 180 in a

counter-clockwise direction causing in this way a displacement of the

small cylinder 83 and of the rod 87 in a sense contrary to that of the

arrow in Figure 8 The end 88 of the rod 87 leaves the shaft 27 and

enters the bore 94 of the lever 91 and locks the delivery device.

Figures 16 and 17 illustrate one of the possible variants of the

safety device in the case in which a printing key is used and Figures

18 and 19 illustrate a second variant of the safety device in the case

in which a non-interpretable key is used.

The safety device illustrated in Figures 16 and 17 is constituted

essentially by a drum lock operating with the well-known system of

pegs distinguished in two series.

A first series 211, 212 and 213 is housed in the holes of a member 210

rigid with a small shoulder 218, each peg having a predetermined

length, whilst a second series of pegs 214, 215and 216 is housed in

holes in a core 217, each peg being biased outwardly by springs.

The key has a fork 201 at the ends of which are fixed bosses 202 and

203 which carry one or more symbols or marks distinguishing each key

engraved in relief Inside the fork 201 is fixed a small plate 204, the

profile of which permits the unlocking of the core 217 of the lock.

The central portion of the key includes a longitudinal hole in which a

pin that connects the thumb piece 206 with the bolt 207 is

accommodated.

The locking of the lock is obtained by means of the pegs 214, 215 and

216, which, by being pushed towards the outside by the springs,

project over the diameter of shim adjustment of the core 217 and enter

into the holes of the member 210, thereby preventing the core 217 from

rotating.

The locking of the apparatus is synchronised with the locking of the

lock by means of a connection between a square cross-sectioned hole

219 in the core 217 and the square crosssectioned extension of the rod

87.

The unlocking of the lock is obtained by introducing the key 201

completely into the groove 208 (Figure 17), of the member 210 and,

while the bosses 202 and 203 are in printing position, the plate 204

which is provided with projections and recesses of determined

dimensions permits the pegs 211, 212 and 213 to lower the pegs 214,

215 and 216 down to the diameter of shim adjustment of the core 217

The unlocking of the apparatus is carried out by means of a clockwise

rotation through 1800 of a thumb-piece 206 which, 70, being rigid with

the bolt 207, drags along with it in rotation the core 217, the rod

connected with the latter performing in rotating a longitudinal

displacement, due to the action of the groove 84, and entering again

into the shaft 27 75 The beginning of delivery determines the movement

of the wheel having front teeth (X) of the group of discs (Y) and the

plate 89 projects over the plane of contact of the core 217 and

accommodates itself in the space obtained 80 in the members 210 and

217 and a dowel 224 rigid with the core 217, which now is turned

upwards owing to the unlocking operation just described, prevents the

return rotation of said core 217 as well as of the thumb-piece 206 of

85 the key However, the pegs 211, 212 and 213, which are inserted

between the grooves of the plate 204 and the surface of shim

adjustment of the core 217, prevent the key from being recovered 90

With the clearing of the computing members, the inclined plane of the

first disc 20 ' retracts the plate 89 enabling the rotation in the

contrary sense of the core 217 which, in returning to the starting

position, determines the un 95 locking of the key thereby rendering it

recoverable.

According to the variant illustrated in Figures 18 and 19, the safety

device is again constituted by a peg-operated drum type lock, 100 but

in this case the key is not interpretable, that is to say, it does not

carry its own mark engraved on it; but it is provided with

supplemental teeth adapted to pre-set the discs of the marks inside

the lock in the print 105 ing position corresponding thereto.

The key is formed by a disc-shaped handgrip 301 from which extends the

plate 302 having a shaped section which in its lower profile presents

two non-distinct series of pro 110 jections and recesses The first

series determines the composition of the distinctive symbols for each

key, whilst the second series determines the unlocking of the lock

(constituted by the well-known peg-system) 115 The clockwise rotation

of the key through determines the unlocking of the apparatus and the

composition of the distinctive symbols of every key The composition of

the distinctive symbols is determined by the 120 dimensions of the

projections and recesses of the first series If the key is introduced,

members 303, 304 and 305 assume the positions determined by said

dimensions and project from the core 306 by a determined amount On 125

the rotation of the key through 1800, the portions of the members 303,

304 and 305 which project from the core 306 meet progressively the

corresponding steps of discs 307, 308 and 309 carrying these along for

the remaining 130 785,776 lock the apparatus and to permit the use of

the machine and means adapted to cause the printing and issuing of the

ticket, the clearing of the numbering printing members and the locking

of the apparatus and of the machine at 70 the end of the operation.

2 A machine according to claim 1, characterised in that the numbering

printing members are constituted by discs arranged along a single

axis, such discs being controlled by 75 means of a toothed gearing in

parallel with the computing or counting devices existing in the

apparatus to which the machine is to be applied.

3 A machine according to claim 1 or 2, 80 characterised in that two

series of discs are provided, one series for the indication and

stamping of the quantity and another 'series for the indication and

stamping of the respective price of the measured or delivered

-product, a first 85 disc, which by means of a system of planetary

wheels controls the other discs belonging to the same series, being

directly controlled by means of a serrated wheel and pawl.

4 A machine according to any of claims 1 90 to 3, characterised in

that the clearing of said numbering printing members is carried out

contemporaneously with the clearing of the computing or counting

devices of the apparatus, transmitting means being provided 95 for

transmitting the movement from said computing or counting devices to

shafts arranged concentrically with respect to the printing members,

such shafts being provided with longitudinal grooves which co-operate

with 100 pawls on the discs to drag the latter along to their zero

position.

A machine according to claim 4, characterised in that the shafts are

provided with flanges each having a notch co-operating 105 with a

wedge-shaped projection of a frame, in which there are supported

planetary wheels, in such a manner as to cause the disengagement of

the planetary-wheels from the discs during the stage of clearing 110 6

A machine according to any of claims 1 to 5, characterised in that the

safety device is constituted by a lock actuable by means of a series

of keys and in that different means are provided to act, during the

operation of un 115 locking the machine, upon printing members

provided with symbols or distinctive numerals for the combination of a

distinctive sign corresponding to the particular key used for the

operation, means also being provided for lock 120 ing and unlocking

the measuring and delivering or dispensing apparatus.

7 A machine according to claim 6, characterised in that each key is

provided with two vanes one of which is provided with a stop, the 125

height of which is different for different keys, co-operating with an

internal stepped profile of at least one disc which externally carries

distinctive signs or numbers for each utilizable key 130 stroke and

taking them with the corresponding symbols to the printing position

Members 310 cause the setting of the discs 307, 308 and 309 during the

whole time of the operation (Figure 4).

The unlocking of the lock is determined by the second series of

projections and recesses which, when the key has been introduced, act

upon pegs 311, 312 and 313 to push pegs 314, 315 and 316 to the point

of shim adjustment of the core 396 with the member 317, thereby

releasing the core 306 The unlocking of the apparatus is determined by

transmitting the rotation of the lock through 180 to the rod 87 which

performs a longitudinal displacement and returns into the shaft 27.

An extension 319 of the key, when introduced into a groove 320 in the

rod 87, establishes the connection between the lock -20 and the

locking of the apparatus 'The beginning of the delivery determines the

rotation of the wheel having front teeth (X) of the group (Y) and the

plate 89 accommodates itself in a groove symmetrical with, and

diametrically opposite to, the groove 322 of the core 306 preventing

the rotation in the contrary sense of the core 306, whilst the pegs

311, 312 and 313, which are inserted between the second series of

recesses and projections of the key and the surface of shim adjustment

of the member 317, prevent extraction of the key, thus rendering it

non-recoverable.

When clearing the computing members, the plate 89 is retracted, by

virtue of the inclined plane of the disc 20 ', with respect to the

groove 322 and the core remains unlocked On rotating the key in the

contrary sense, the members 324, 325 and 326 return the discs 307, 308

and 309 to the starting position; the extension -40 319 returns the

rod 87 to the locking position; and finally the pegs 311, 312 and 313,

by returning to correspond with the holes in the member 317, permit

recovery of the key.

Obviously the mechanical means of the -45 machine hereinbefore

described may undergo various modifications and may be replaced with

analogous means without departing from the scope of the present

invention.

Finally, and if desired, additional means :50 may be provided for

locking the machine in case of the exhaustion of the supply of paper

for the ticket and/or control sheet.

While this invention is susceptible of embodiments in many different

forms, there is shown in the drawings and will herein be described in

detail one specific embodiment, with the understanding that the

present disclosure is to be considered as an exemplification of the

principles of the invention and is not intended to limit the invention

to the embodiment illustrated The scope of the invention will be

pointed out in the appended claims.

Referring now to the drawings there is shown a parklng meter 10 having

a housing divided into an upper portion 11 and a lower portion 12

Means are provided for supporting the housing on a post 13 standing

along the curb in the usual manner The upper housing 11 ' houses the

parking meter mechanism generally indicated at 14 which includes a

coin receiving portion 15 protruding forwardly of the meter mechanism

with such portion being provided with ia coin receiving slot 1,6 and a

manually actuable handle 17 for operating the meter and setting the

dials, etc.

H Iingedly mounted on the upper housing portion 11 ' is a ca p 18 in

the form of a half moon, or semi disk which is provided with a pair of

transparent windows 19 on either side of the centre portion of the cap

through which the dial and violation flags of the meter may be viewed.

Referring now to Figs 4 to,7 inclusive, it wilt be noted that the

upper housing portion 11 is provided with an internal recess 20

adapted to receive the parking meter mechanism 14 and the front wall

21 of the housing is provided with a cut-out portion 22 through which

the coin receiving portion 15 may extend when the mechanism is

properly positioned within the recess 20 The upper edge 23 of the

recess 20 is stepped as shown in Figs 6 and 7 and the lower edge 24 of

the cap is stepped in a complementary fashion so that when the cap is

seated upon the housing portion 11, a weather-tight juncture

therebetween is assured.

The cap 1 '8 is hingedly secured to the housing portion 11 and for

this purpose there is provided a hinge member 25 having an upper

portion generally in the form of a yoke including tvo spaced legs 26

and 27 which at their upper ends are bent over a hinge pin 28 which

extends through apertures in lugs 29 affixed to the inside of the cap

18 The 70 hinge member 25 is movable upwardly within the housing

recess 20 so that the complementary stepped portions 23 and 24 of the

housing edge and cap edge respectively may continue even at the

location of the hinge For this 75 purpose the hinge member 25 is

provided with a slot 30 embracing a bushing 31 fixed in a side wall of

the housing portion 11 By virtue of this construction the hinge member

25 may slide upwardly when the cap is pivoted 80 to open position

(illustrated in Fig 6) and downwardly to the position shown in Fig 7

when the cap is closed.

For locking the cap in closed position there is provided a crank arm

means 35 comprising 85 a pair of crank levers 36 and 37 each having a

substantially vertically upwardly extending arm 38 and a generally

horizontally extending arm 39 The crank levers are pivoted at and 41;

respectively to the sides of the recess 90 The upwardly extending arm

38 of each crank lever is provided at its upper end with a hook

portion 42 adapted to engage and hook over a rod 43 ' fixed to lugs 44

depending from the cap 18 95 A key operated locking device is provided

for pivoting the crank arms 36 and 37 about their pivots to cause

engagement between the hooks 42 and rod 43 and simultaneously to lock

the hinge member 25 against vertical 100 movement 'A key operated lock

50 is provided in the housing including a portion 51 rotatable in the

fitting 31 and provided at its outer end with a lock member 52 having

a camm ing portion 53 at one side thereof and a lip 54 105 at an

opposite side thereof Rotation of a key inserted in the lock 50 serves

to rotate the lock member 52 and thus to move it from the position

shown in Fig 6 to that shown in Fig 7 In the latter 'figure the lip 54

passes 110 over the top of and engages a lip 55 provided on the hinge

member 25 and thus not only moves the hinge member downwardly, but

effectively prevents upward movement of such member Rotation, of the

lock member 52 also 115 causes the cam portion 53 to engage a bar 56

rockably secured to and extending between the free terminal ends of

the arms 39 of the crank lever means 35, such rotation moving said

ends downwardly and pivoting the crank 120 levers in a

counterclockwise direction (as seen in Fig 6) 6 to move them into a

position engagIng the hooks 42 with the rod 43 Thus the locking of the

hinge member 25 at one side of the recess and the engagement of the

hooks 125 42 and rod 43 at the opposite side of the recess serves

effectively to lock the cap in position When the cap is so locked in

position, no parts of the locking mechanism are exposed and thus are

not in position to be tam 130 7815,f 777 accurately positioning the

entire mechanism within the housing The housing itself is locked with

the mechanism so positioned by operating the lock 50 to rotate the

locking member to the position of Fig 7 Because of the fact 70 that

the bar 56 is rockably mounted on the end of the arms 39, greater

manufacturing errors can 'be tolerated in the 'apparatus as should one

of the hooks 42 engage with the rod 43 before the other hook 42 makes

an en 75 gagement, the rocking 'bar 56 may tilt slightly thus

permitting one of the crank levers to pivot more than the other.

The housing portion 12 below the recess 20 and into which the slot 74

opens may of course 80 be provided with the usual coin, box for

receiving coin together with a hinged door 8 '5 which mlay be opened

to give access to the coin box.

bringing about HeatExchange between Slurry and' Hot Gases We, 'F L

SMIDTH & 'Co, A/S, a Danish Company, of 7,7 Vigerslev j Alle,

lCopenhagenVallby, Denmark, do hereby declare the invention for which

we pray that a patent may be granted, to us, and the method by which

it is to be performed, to be particularly described in and by the

following statement: -

A known form of apparatus for bringing about heat-exchange between

slurry and hot gases comprises a rotary drum mounted about a

horizontal or inclined axis and divided into sections by two or more

compartments, running axially through the drum, each compartment

having parallel porous walls and usually containing 'a charge of loose

bodies The construction is such that in order to pass axially through

the drum the slurry and gases must flow through at least one

compartment in directions substantially at right angles to the axis

The drum is commonly a rotary kiln, and the compartments occupy only a

short part of the length of the kiln.

This form of apparatus will be more readily understood by reference to

the accompanying drawings, in which Figure 1 is a cross-section and

Figure 2 is an elevations, partly in section on the line II-II in

Figure 1.

In this typical apparatus the drum is ian inclined rotary kiln 1

supported on rollers 2.

The ends of the kiln project into stationary hoods 3 and 4, the hood 3

being located at the outlet end for the material to be treated and the

hood 4 at the inlet end Raw material is introduced as slurry through

'a pipe 5 The kiln is fired by fuel fed through a burner pipe 6

projecting into the outlet end and the combustion gases leave the kiln

through a pipe 7.

Near the inlet end of the kiln four compartments 8, 9, 10 and 11

extend radially across the kiln to divide it into four sections 12,

131, 14 and 15 The ends of the compartments are closed by solid walls,

and the lower ends of the sections 12 and 14 ' are closed 'by plates

16 while the upper ends of the sections 13 and 15 are closed by plates

1 f 7 The opposed parallel walls of each compartment lPrice 3 s 6 d l

partly consists of grates 18 through which both slurry and gases can

pass Each compartment contains a charge of loose bodies.

In operation, slurry at a temperature of about 10 to 200 C is

introduced through the pipe 5 and flows down the kiln' It can enter

the sections 12 and 114, but not the sections 13 and 165, and it

cannot leave the sections 12 and 14 axially because it is stopped by

the plates 16 The hot gases flowing up the kiln can enter the sections

13 and 15 ' 'but are prevented by the plates 17 from leaving these

sections axially However, as the kiln rotates from the position shown

in Figure 1, in the direction indicated by an arrow, the slurry inside

the section 12 can pass through the grate 18 of the compartment 8 into

the section 15, and thence can flow further down the kiln.

The hot gases after entering the sections 13 and 15 can pass through

all the compartments into the sections 12 and 14, and thence further

up the kiln to 'the hood 4 Eflicient heat exchange takes place between

slurry and gases along the grates 118 ' and inside the lcompartments 8

to 11.

Now the practice hitherto has been to fix the compartmenits to the

inner wall of the kiln or other drum 'at diametrically opposite

positions and to join the inner ends of the 'compartments together all

as shown in Figure 1, so that the compartments and drum form 'a rigid

structure However, when a drum supported on roller bearings is rotated

its crosssectional shape continuously alters under the weight of the

drum, and the compartments are therefore 'constantly subjected to

varying stresses Moreover, the drum itself, being exposed to varying

amounts of heat, undergoes temperature changes which lead ito changes

in shape In turn these increase the stresses to which the compartments

are subjected The result is that the walls of the compartments are

deformed or damaged.

According to the present invention the risk of deformation or damage

is reduced in that as seen in cross-section' eacht compartment is

85,778 fixed at only one end to the drum and is connected at or close

to the other end to another compartment by a flexible connection.

Preferably the compartments are arranged in one or more pairs, the two

compartments of each pair extending radially inwards towards one

another but not reaching the axis of the drum and having

semi-cylindrical inner ends.

One apparatus according to the invention is shown in cross-section in

Figure 3 of the accompanying drawings In this Figure equivalent parts

are identified by the same reference numerals as in Figures 1 and 2 It

will be seen that each compartment is fixed close to one end in the

wall of the kiln The compartments 8 and 11 are connected to each other

at their inner ends by means of a flexible member 19 of, for example,

spring steel; the compartments 9 and 10 are interconnected in a

similar manner Thus any changes in the shape of the kiln will have

practically no mechanical influence on the compartments.

It will be seen that each compartment is connected by a flexible

connection to a compartment next, but not opposite, to it so as to

divide the drum into three sections In other words the sections 12 and

14 merge into one, but this does not matter as these sections are

parallel passages for gases and slurry.

It w Ill,also be seen that each compartment projects outvards through

the wall of the drum and as seen in cross-section has a

semicylindrical outer end Moreover the inner ends 20 are also

semi-cylindrical and thus serve as rigid supports for the coupling

members 19 and furthermore relieve the fall of the loose bodies during

the rotation of the kiln so that the wear on the apparatus and the

noise developed from it are substantially reduced.
