ting into each other like cogs. The strap to be fastened is passed between the top plate of the angular box and this roller, so that the more the strap is pulled, the tighter it is squeezed by the turning of the roller against the upper plate. The angular box is provided with the requisite loops for retaining the straps in their proper directions. The roller is connected with the lower grooved plate of the angular box, by a strap which embraces the middle part of the roller, reduced in size for that purpose, and passes down through a slot in the plate and is there provided with a plate.

Claim." What I claim as my invention, is the construction and use for all similar purposes with other buckles, of the following parts of my angular box and grooved roller buckle, to wit, said grooved roller moving upon the grooved surface of the back section of the angular box, and the manner of its attachment to said back section by means of a loop or ring, and a slide, so that the same retains its place and acts upon the strap required to be held by pressing it against the bridge or front section of said angular box, and any and every thing essentially the same: all other parts of said buckle being disclaimed as like, or similar, to those of other buckles now in common use."

12. For an improvement in Buckles, or Apparatus for Connecting Straps; Charles F. Beverly, Salem, Columbiana county, Ohio, January 16.

This differs from the preceding only in the use of a lever for the roller, so arranged, that, as the part which bears upon the strap, and which is notched for that purpose, is drawn forward by the strap, a catch on the upper surface of the lever is received in a lower tooth of an inclined rack attached to the grooved bottom plate, and thus the lever is caused to gripe the strap the tighter.

Claim. "What I claim is the method of fastening together the ends of straps and other articles by a combined hinged convex lever and serrated plate, and adjustable sliding bar, whether constructed and arranged in the manner set forth, or other mode substantially the

13. For an improvement in the Press for Compressing Cotton, Hay, &c.; Philos B. Tyler, New Orleans, Louisiana, January 16.

The nature of this invention consists, in applying power to the compression of cotton, or other substances, through the intervention of two sectors, gearing into a double rack, or connected with the piston rod by connecting chains in a manner well known to all mechanics, attached directly to the piston of a steam cylinder, and connected with the platen by the means of two bars or rods, said connecting rods being attached to the sectors at a point within their circumference, which when they revolve by the action of the racks, raise the platen with a power increasing in the proportion, or nearly so, of the increased resistance of the material under pressure.

Claim." What I claim is, the arrangement of the sectors and double rack piston rod in combination with the follower of the press, by means of the connecting rods, to adapt the movement of the platen or

follower, to the increased resistance of the cotton, and thus attain the greatest amount of effect, with the least expenditure of power, as described."

14. For an improvement in Water Wheels; James Gardner, South Lee, Berkshire county, Massachusetts, January 16.

Claim. What I claim as my invention, is the manner in which I construct my water wheel-that is to say, the form of the buckets having two distinct curves, one of the curves projecting beyond the periphery of the wheel into spiral shutes; the curves on the face and back of the buckets corresponding; and in combination there with the openings in the bottom of the spiral shutes for the discharge of the water."

15. For an improvement in the Endless Floor for Horse Powers; Luke Hale, Hollis, New Hampshire, January 16.

This is for a method of forming and uniting the chains of an endless floor for a horse power.

The claim is in the following words, viz. "I shall claim the mode of firmly uniting together by one screw bolt the several parts of the three links, B, C, C, and the floor board, viz. by a combination of ears d, e, cast upon the inner sides of the two portions of the link B, so as to lap over each other and permit the screw bolt to pass through them and operate upon and with respect to the several parts, as described."

The link, designated in the above claim by the letter B, is composed of two plates of metal, the ends of which are provided with holes to receive and embrace journal or joint pins on the ends of the two links C, C, one at either end, and these two plates are cast with ears d, e, that lap on each other so that a bolt passing through a hole in them, and through the end of the floor board, secures the whole together.

16. For an improvement in Piano Fortes for producing the harmonic Tones; Lesley Walker, Carlisle, Cumberland county, Pennsyl vania, January 16.

"The nature of my invention consists in producing harmonic tones an octave higher than the original sound of the strings of the piano forte, ad libitum, by means of a set of hammers or weights which are placed in a frame over the strings, and are brought down upon them at the centre of their length by a pedal or other analogous device under the piano, similar to what is used at present to control the soft pedal or damper frame."

Claim. "What I claim as my invention, is an extra set of hammers, weights or dampers, or a continuous bearing, constructed and arranged as described, passing over the centres of the strings of a piano forte, so as to be brought down upon them by a pedal or other analogous device for the purpose of producing the harmonic tones, as set forth."

17. For an improvement in Railways; Wm. M. C. Cushman, Albany, New York, January 16.

This improvement is for capping cast iron base rails with wrought iron in a manner to protect the sides of the base rail, and prevent the rails and caps, at the junctions, from moving out of the proper line.

Claim."I am aware that cast iron base rails have been capped with wrought iron rails, and therefore I do not claim this as my invention; but what I do claim as new and desire to secure by letters patent, is connecting the cap rails with the base rails, by means of a fillet, flanch, or rebate, as described, so that by breaking joints the base and cap rails will be retained in their proper lines at the joints, and the cap rails may be extended up to or beyond the inner edge of the base rail, and thus prevent the flanches of the wheels from acting against the base rails.""

18. For a machine for Pulling Flax; James H. Bennett, East Bennington, Vermont, January 23.

This machine consists of two or more fingers, (like those of a grain cradle) attached to the end of an appropriate handle, on which there is a slide with one or more fingers fitting between those on the handle, and by means of the slide the flax on the field is griped between the two sets of fingers-the slide on the handle being provided with a lever handle, toggle joint, or other analogous device for operating it. Claim. "What I claim as my invention, is the manner of grasping the standing flax for the purpose of pulling it, between the fingers or jaws by means of the movable part sliding and receiving its motion in the direction of the handle from the crank neb, by means of a slot and pin, or toggle joint, as described."

19. For an improvement in the machine for Boring and Mortising Hubs, applicable to other purposes; Reuben D. Roys, and Newell French, Detroit, Michigan, January 23.

Claim. "We claim the combination in the mandrel of a rotary motion for the purpose of boring and drilling, with a vertical motion, for the purpose of mortising, the mandrel taking both motions in the former operation, and the vertical only in the latter."

20. For an improvement in the mode of Casting the Bowl on the stand or pedestal in the process of making Glass Lamps; P. F. Slave, and John Golding, East Cambridge, Middlesex county, Massachusetts, January 23.

In performing this operation in the old method, the pedestal first moulded is put into the mould and the bowl then put on by blowing; but the improvement in question is for the purpose of avoiding this difficulty by having a platform to receive the pedestal of the lamp, and above it a shaft to receive the upper end of the pedestal, and which at the same time forms the base of the mould for the bowl. Claim. "We do not claim as our invention combining the bowl of the lamp with the stem thereof by blowing it on, as that has before,

been done, but what we do claim is combining the mould for the bowl of the lamp, constructed substantially as set forth, with the hori zontal shelf (into which the top of the foot of the lamp is fitted) and the platform on which said foot rests, by which the connexion or cementing of the bowl and foot is accomplished in a truer and more perfect manner than it can otherwise be done, the whole arrangement being substantially as described."

21. For improvements in machinery for Making Wood Screws; Simeon Brooks, and Wm. N. Clark, Chester, Middlesex county, Connecticut, January 23.

In this case we are under the necessity of omitting the claims, as they refer to and are wholly dependent on the drawings, the publication of which, from their necessary complexity, would carry us beyond the limits of this work; but they are limited to the following arrangements. The first section refers to the machine for paring the head of the screw, and consists of the combination of the lever which carries the cutter or tool with another lever connected with it, and a spring the lower end of which embraces the shank of the screw, back of the head, so that by withdrawing the tool or cutter by the hand of the attendant, the second lever is operated which forces the spring back and discharges the screw blank from the jaws that have been opened previously in a manner well known. The second section refers to the machine for nicking the heads, and is limited to an arrangement of parts for presenting the screws to the action of a circular saw on a mandrel by means of a face plate (having holes near its periphery that receive the screw,) operated by a series of levers to insure the cutting of the nick to the required depth, and then to shift the face plate-the whole being performed by the movement of two levers by the hand of an attendant.

And the third section refers to the threading machine, which cuts the threads by means of two roller dies one of them having its bearings in sliding boxes moved by means of a gauge rod to regulate the cut of the threads. This gauge rod is wedge-formed at that part which operates the slide of the die, and is so connected with the spindle of the jaws that carry the screw, as to force the dies together, as the point of the screw approaches them, to cut conical screws. It is to this arrangement and combination of the gauge, that operates the slide with the spindle of the jaws, that the claim is limited.

22. For improvements in the apparatus for Generating, Condensing, and Burning Gas from Oil, Resin or Coal, &c.; Benj. F. Coston, Washington, D. C., January 31.

Claim. 1st. I claim the method of introducing the resin or fat into the retort by means of the feeder G, and pipe H, and tube H'; as above described, directly on to the coke or other charge in the retort, whereby the disadvantages arising from the collection of sediment in the ordinary syphon tube are obviated, and the resin or oil is introduced into the hottest part of the retort, without any portion coming in contact with the sides.

2nd. I claim the jacket around the pipe that conveys the gas to the condenser, in combination with the cistern of the gasometer, in the manner and for the purpose described, thus keeping the pipe cool and preventing the tar from baking on to said pipe. 3d. I claim the combination of a condenser constructed and arranged, as made known, with the retort, and gasometer, for the purposes herein specified, to condense the gas that passes through it, and having a cistern below to draw the tar into.

"4th. I claim constructing the gas burner in the manner described, having a long double tube with a conical chamber above it as specified, so as to heat the gas to a high temperature before burning.Lastly. I claim the mercurial joint, constructed and arranged substantially as set forth, for passing gas from a stationary to a revolving pipe, as described."

The above claim refers to the drawings, and as they are too numerous to admit of publication within the compass of our notices of patents, we will explain the nature and functions of the parts simply indicated by letters.-Section first. The pipe H, is a pipe extending up from the top of the retort, closed at top, and having another and smaller pipe H' passing through it and extending down about half its length, and extending up into and near to the top of a small cylindrical feeder G, above it, and from near the bottom of this feeder another pipe extends up to the cock of a kettle that contains melted resin or fat. Section second. The pipe J, for conducting the gas from the retort to the condenser, is surrounded by a jacket through which a stream of water passes from the condenser to keep the pipe J, cool. And section last. The mercurial joint of the stationary and revolving pipes is thus formed: The end of the revolving pipe rests on the other by a pivot, and both are pierced with holes, surrounded by a double cup, half of which is attached to each pipe, so that a flanch from the upper one will dip and run in a groove or channel in the under one, made of such depth as to contain a column of mercury, sufficient in height to resist the pressure of the gas, which by this arrangement escapes from the holes in the end of one pipe and passes in to the other-the mercurial cup preventing its escape.

23. For improvements in the machine for Reaping Grain; Cyrus N. Mc Cormick, Rockbridge county, Virginia, January 31.

This is for improvements on that kind of machines in which the grain is cut by the serrated edge of a straight and vibrating cutter, operated by a crank, the grain being sustained by fingers. The blade is serrated like a sickle except that the angle of the teeth is reversed for every alternate tooth, and the supporters of the blade are secured by screws to the front part of the platform, and bent down and then up to give a free escape to straw which may enter the machine.— The fingers for supporting the grain are spear-formed and the angle of the edge begins to run in forward of the edge of the cutting blade, so as to form an angular shear to insure the support of the grain in the act of cutting. The other improvements are fully pointed out in the following claim.
