18. For an Improvement in Straw Cutters; G. Catchpole, Geneva, Ontario county, New York, September 5.

Claim." Having thus fully described my improvements, what I claim as new therein, and desire to secure by letters patent, is, first, the combination of the sliding gate, front block attached thereto in a stationary manner, and top roller, in the manner described; the said plate sliding in grooves in the outside plates of the frame, by which it is steadied and directed.

"Secondly, I claim constructing the rollers, as described, so that the top roller gathers in faster than the bottom, to prevent clogging, in the manner set forth."

19. For an Improvement in Windlass, and other Bedsteads; Joseph W. Adams, (assignor to Simon H. Lewis & J. C. Clapp,) Boston, Massachusetts, September 10.

The patentee says,-"The great objections which have been met with in the use of windlass bedsteads, as they now are, and have been heretofore, constructed, are, that as the sacking has been merely tacked, or nailed, to the side swell beams, the fabric is liable to break away from the nails, or tacks; and when, for this reason, and for the loosening of the cords which confine the sacking to the end swell beams, or for other reasons, the said sacking becomes loose or slack, the whole frame-work of the bedstead becomes 'ricketty,' so to speak. My improvements are designed to remedy these objections, and consist in a new mechanical arrangement for securing the sacking to the side beams, and a simple additional fastening for securing, more perfectly, the two side and two end beams, at their ends, to, or in, the mortises of the upright corner posts of the bedstead."

Claim. Having thus described my improvements in windlass, and other bedsteads, I shall state my claim as follows: What I claim as my invention, and desire to have secured to me by letters patent, is the mode, herein above described, (or any other mode substantially the same,) of inserting the confining pins, at the four corners of the bedstead frame, so that when the keys are driven into the holes in the ends of said pius, the strain on the frame all around shall be in the same horizontal plane."

20. For a New and Improved Cooking Stove; William H. Allen, Wellsburg, Virginia, and James Slocum, Brownsville, Pennsylvania, September 10.

The patentees say,-" The nature of our invention consists in constructing a cooking stove in such a manner as that it can be readily changed from a wood to a coal stove, by removing a movable ash-pit hearth, and placing a grate and fire-plates in the front part of the stove, as described."

Claim. Having thus fully described our improved cooking stove, what we claim therein as new, and desire to secure by letters patent,

is the manner in which we convert a single oven coal stove into a donble oven wood stove, by the withdrawal of the grate, and the insertion of the movable ash-pit hearth, arranged, combined, and operating with the air-chamber, or flue-space, substantially as set forth."

21. For a Machine for Sewing Seams in Cloths or other articles requiring to be sewed; Elias Howe, Jr., Cambridge, Middlesex county, Massachusetts, September 10.

The patentee says,—“ In sewing a seam with my machine two threads are employed, one of which threads is carried through the coth by means of a curved needle, the pointed end of which is to pass through said cloth; the needle used has the eye that is to receive the thread within a small distance, say an eighth of an inch, of its inner or pointed end. The other or outer end of the needle is held by an arm that vibrates on a pivot or joint pin, and the curvature of the needle is such as to correspond with the length of the arm as its radius. When the thread is carried through the cloth, which may be done to the distance of about three-fourths of an inch, the thread will be stretched above the curved needle, something in the manner of a bowstring, leaving a small open space between the two. A small shuttle, carrying a bobbin filled with silk or thread, is then made. to pass entirely through this open space, between the needle and the thread which it carries; and when the shuttle is returned, which is done by means of a picker staff or shuttle-driver, the thread which was carried in by the needle is surrounded by that received from the shuttle; and as the needle is drawn out, it forces that which was received from the shuttle into the body of the cloth: and, as this operaton is repeated, a seam is formed which has on each side of the cloth the same appearance as that given by stitching; with this peculiarity, that the thread shown on one side of the cloth is exclusively that which was given out by the needle, and the thread seen on the other side is exclusively that which was given out by the shuttle. It will, therefore, be seen that a stitch is made at every back and forth movement of the shuttle. The two thicknesses of cloth that are to be sewed are held upon pointed wires, which project out from a metallic plate, like the teeth of a comb, but at a considerable distance from each other-say three-fourths of an inch, more or less; these pointed wires sustaining the cloth, and answering the purpose of ordinary basting. The metallic plate from which these wires project has numerous holes through it, which answer the purpose of rack-teeth in enabling the plate to be moved forward, by means of a pinion, as the stitches are taken. The distance to which said plate is moved, and consequently the length of the stitches, may be regulated at pleasure."

Claim. "Having thus fully described the manner in which I construct my machine for sewing seams, and shown the operation thereof, what I claim therein as new, and desire to secure by letters patent, is, first, the forming of the seam, by carrying a thread through the cloth by means of a curved needle on the end of a vibrating arm,
