so as to prevent the escape of steam between the cap and the chamber, without the use ot packing; and the pressure of the cap upon the revolving chamber by means of springs, to effect the same object."

71. For a Cradle for Cutting Ilemp; Wilson A. Larimore, Paris, Bourbon county, Kentucky, April 25.

This is a modification of the common cradle, fitting it to the purpose of cutting hemp by hand. The claim is to " the construction era bow, or guard, around the points of the fingers, and its extension to the post. Likewise the cord which confines the how, and extends to the sneath. Likewise the con. fining of the scythe at the point to the frame, by a screw or otherwise. Likewise the hoop confined on, or near, tile back of the scythe."

The object appears to be to render the instrument firm and steady, for cutting the heavy substance to which it is to be applied.

The points of the fingers are inserted into a hoop, connecting them to. gether there as well as at their back ends, and from the frame thus formed a rope extends to the upper end of the sueath, to support said frame.

72. For an instrument for Measuring~ and Draug~hting, preparatory to cutting out Garments; Will iam C. Bishop, Ovid, Seneca eounU, New York, April 25.

We have a specification and drawing of this instrument, but do not sup- pose the sui)ject of sufficient general importance to justit~, the expense of an engraving, and the space for the description. The instrument consisls of flexible graduated metallic straps, to which measuring tapes are attached, and the claim is to " the particular mode in which they are connected and arranged~" which so far as we can judge in a matter foreign to our general pursuits, appears to adapt them well to the purpose intended.

73. For an improvement in the Collo~ Gin; Alexander Jones, City of New Orleans, April 25.

The principal improvement in this cotton gin consists in the manner of iheding the seed to be cleaned. Tile seed is put into hoppers, the bottoms of which are tbraled of parallel bars, the spaces between these bars being such that the seed cotton may be drawn through by the teeth of revolving l~ed plates, constructed tbr that purpose. To regulate the teed the hop- pers are made to raise and lower, giving to the teeth of the feed plates more or less hold. The claim is to" the method of feeding the cotton to the saws by means of hoppers and feeding cylinders, constructed and operating substantially upon the principles set ibrth."

74. For a Bodkin for insertin,~ Corset Rin~s; Jonathan S. Turner, Middletown, Middlesex county, Connecticut, April :25.

Corset, or other grooved rings, are to be inserted into cloth or canvass by means of an instrument that will make a hole in the cloth of the size of the neck of the ring to be inserted, and at the same time convey the ring into the cloth. A taper bodkin is to be made of ivory, or other suitable material, and this is to be cut across at such distance from the point where it is equal to the diameter of the grooves, the two sections terming a point and handle. From the handle a pin is to project about an inch in length, and of a size fitting the hole in the corset ring. The point is to be bored to re-- c.ei've the pin projecting trom the handle, and the instrument is complete.
