2. For improvements in the Printing Press; John L. Kingsley, New York city, New York, January 4.

The patentee says " In my improved press the inking apparatus, and that for making the impression, are in their general construction, similar to those employed in the most improved machines, but they are so modified and arranged as to adapt them to an entirely new apparatus for conveying the sheet to the required positions for printing them on both sides, or what is technically called perfecting the sheets; which is done before the sheets leave the gripper, by which they are deposited correctly in a pile ready for drying. By this ar rangement, one person is required to feed the machine by supplying the sheets to be printed, the press being actuated by any adequate power.

In a machine thus arranged, one half the labor of feeding required in the best registering machine with which I am acquainted, namely, that of Tuft's, of Boston, is saved, and with the employment of two persons at the feeding board; his press affords only about six hundred impressions in an hour, whilst, as my machine takes two impressions to one sheet supplied, and the printed sheet is deposited without interfering with the feeder or feeding, it may be run at any speed which allows time merely for the inking and the supply of sheets, and may consequently make from twenty to twenty-five hundred impressions in an hour. My machine secures a perfect register, as the sheet which has been fed in the gripper does not leave them until it is per fected, when it is deposited as hereinafter described."

Claim." What I claim therein as new, and desire to secure by letters patent, is the arrangement of the grippers combined with the carrying belts, by which I am enabled to carry in the paper, hold it, and retain it until it is perfected, by which it prints it on both sides and then deposits it; the operations being effected by so combining the sheet apparatus with the inking rollers as to give the carrying belts and grippers an intermitting progressive movement, as described.

I also claim in combination with the printing apparatus, the so ar ranging of the carrying belts as to return the sheets of paper which have been printed on one side at nearly the same level which they occupied when they received the first impression, they being in both cases at the proper elevation for giving the impression as described.

I claim likewise, the manner in which the grippers are made to open and close by means of a spring operating to force and hold them open, and bolts for holding them when closed, in combination with the closer and opener, substantially as set forth."

3. For an improvement in the Cylinder Brush used in the Saw Gin for ginning Cotton; Ebenezer Carver, Bridgewater, Plymouth county, Massachusetts, January 4.

The patentee says

"The design of my improvement is to enable the brush to produce a sufficient and regular current of air through the gin so as to dis

charge the clean cotton through the machine in a better manner than has heretofore been done.

In the operation of the common gin, the brushes usually employed for taking the cotton from the teeth of the saws and discharging it through the gin, are liable to produce eddies and counter currents of air in the gin which interrupts the regular and direct passage of cotton through the machine, and causes it sometimes to collect at the ends of the brush in such quantities as to retard its motion and endanger the machine.

This difficulty I obviate by the application of what I call fans to the ends or heads of any cylinder brush extending from the axis to the outside of the cylinder and standing out or projecting from these heads from one to two or more inches according to the length of the brush.

Claim." Having thus described my improvement and its advantages, I now claim as my invention and desire to secure by letters patent, the combination of a cylinder brush having fans on the end thereof, with a cotton gin for the purpose and in the manner herein set forth, or in any manner substantially the same."

4. For improvements in Stoves for Heating Apartments; Henry Stanley, Poultney, Rutland county, Vermont, January 4.

Claim. "What I claim as new, and desire to secure by letters patent, is the manner in which I have combined and arranged the two stories thereof, consisting of two cylinders, with eight triangular radiating flues arranged around, and in contact with them, said flues communicating with the flue space in the plinth, with the intermediate chamber, and with the cornice space, as described; the two latter being divided by partitions into anterior and posterior portions, in the manner and for the purpose set forth; and there being also openings, such as are herein described, and represented, through the upper end of the upper cylinder into the cornice space, in the manner and for the purpose above made known; it being distinctly understood, that I do not make any claim to either of the individual parts taken separately and alone, but that I limit my claim to the combination and arrangement thereof as a whole: not intending however, by this claim to confine myself in constructing my stove to the particular form of the respective parts as described and represented, but to vary these as I may deem expedient, whilst I attain the same end by means substantially the same."

5. For an improvement in the Cooking Slove; Charles Wolff, Cincinnati, Ohio, January 4.

Claim." What I claim as my invention, and desire to secure by letters patent, is the two horizontal flues, in combination with the ovens, their bottom plates forming parts of the top of the oven, their inner plates forming partly two sides of the same, their top plates being formed by the hearth plate, and their outside plates by the side plates of the stove. I do not claim merely to conduct the heat

all around the oven, but I do claim the particular arrangement of the flues to effect the said object as herein above described.

6. For an improvement in the mode of Arranging a Reciprocating Steam Engine to turn two parallel shafts; J. H. Towne, Philadelphia, Pennsylvania, January 10.

The following is extracted from the patentee's explanation, viz:— "The engine is to have a vibrating cylinder, sustained upon suitable trunnions, through which, if desired, the steam may be admitted into the cylinder, but it may, if preferred, have other provisions for the admission of steam, which need not be described, as it is not intended to make claim to any particular manner of doing this, but to use such as are already known, or which may be hereafter devised.

In my engine there are to be two piston rods in a line with each other, which rods are to pass through the two cylinder heads, each head being provided with a stuffing box. The piston rods are each to be connected with a crank at their outer ends, so that each actuates the shaft of a wheel for propelling, or for any other purpose, and cause said shaft to revolve in opposite directions.

One of the connexions of the piston rod with its crank is to be made by the aid of a link, or of a sliding box, admitting of a slight degree of lateral play, to prevent cramping as the cranks revolve."

Claim.-"I claim therein as new, and desire to secure by letters patent the manner in which I have arranged the same so as to connect two piston rods, proceeding from one piston to two driving shafts, for the purpose of turning them simultaneously in the opposite direction as set forth. I likewise claim in combination with the two piston rods, the connecting of one of them to one of the crank pins, by means of a link, or some equivalent devise, allowing of the amount of the lateral motion necessary to enable both cranks to revolve with perfect freedom.

I do not claim the passing of the two piston rods through the two heads of a cylinder, as in itself new, this having previously been done: but I limit my claim to the combination and arrangement by which I effect the object that it was the purpose of this invention to accomplish, as set forth, and applied to the vibrating cylinder steam engine."

7. For an improvement in the machine for Planting Potatoes. Enoch Woods, Beloit, Rock county, Michigan, January 10.

This machine consists of a plough for opening the furrow, two reversed mould boards, for forming the ridges, a hollow tooth for opening the drills and conducting the seed to the drills, and these are all followed by coverers and a roller. The planting apparatus consists of a pricker which pricks into the potatoes, lifts them up from the hopper, and carries them against a scraper by which they are removed from the pricker, on its back movement, and dropped into the tube of the hollow tooth and thence conducted to the drills. The lever of the pricker is operated by pins on a wheel, receiving its motion by a belt from the axle of the carrying wheels.

Claim.—“What I claim as my invention, is the combination of the apparatus for dropping or planting potatoes, with the apparatus for ploughing the ground, opening the drills, and covering the seed, as described."

8. For a machine for Backing Books, for Book-binders; William Laighton, Portsmouth, Rockingham county, New Hampshire, January 10.

The patentee says "The operation of backing consists in giving that roundness or convexity to the back of the book which is necessary to prepare it for the reception of the covering of leather or other material. This process is usually performed by confining the book after it has been stitched and cut, between suitable boards or plates of metal, which are pressed firmly together by means of screws, and the back is then hammered into the desired form. In my machine, the book to be backed is confined between two plates, or jaws of iron, which is made to clasp it firmly, as if between the jaws of a vice, and these plates are so arranged as when closed to constitute a carriage, which, by means of a rack and pinion, is moved on in a straight line, so as to bring the back of the book against a roller, or against a block of iron, or other metal; when a roller is used it is made hollowing or concave on its periphery, and is so adjusted as to force the back of the book to assume the desired convex form, leaving it perfectly straight from end to end, and giving to it an equal convexity in all its parts. When, instead of the concave roller above named, I use a block of iron or other metal, which is made to occupy the place of the roller, said block has that side of it which is towards the back of the book, made concave, or hollowing lengthwise, and the back of the book as it is passed along being made to press against the block, receives the desired form; this latter manner of forming the instrument possesses some advantages over the roller, and will probably be generally preferred.

Claim."What I claim therein as new, and desire to secure by letters patent, is the manner herein described of causing the back of such books to be carried along against a fluted roller, or block of metal, whilst they are confined between the jaws of what I have herein denominated the backing irons, the respective parts of said machine being arranged and operating substantially as herein fully made known."

9. For an improvement in machinery for Making Pelisse Wadding, or Batting; Oliver Tenny, Dorchester, Norfolk county, Massachusetts, January 10.

In this machine the bat is sized without an endless apron. It passes directly from the sizing rollers over a small roller at one edge of a vertical chamber, descends nearly to the bottom thereof, and then up again over another roller at the other side of the chamber, and is there delivered and rolled up. A stove is placed at the bottom of the chamber and communicates by a pipe with a long drum near the top, the sides of which with the upper part of the chamber, which is arVOL. X, 3RD SERIES-No. 4.-OCTOBER, 1845.

21

rowed for this purpose, constitute two passages or flues for the heated air at each side of the bat as it enters and leaves the chamber.

Claim." What I claim consists, in the manner in which I effect the drying of the sized bat without the employment of chain aprons or conveyors, such as are generally used therein, viz. by means of the long vertical apartment (for the reception of the bat and hot air) and (in combination with) a passage or flue (for the discharge of the air in a current) proceeding from the upper part thereof; the same being arranged with respect to the size rollers, and the bat being carried through the said passage and into the hot air apartment, and out of the latter through a passage or outlet, and received and wound upon a beam substantially as described."

10. For improvements in the apparatus for Working a Vertical Forge Hammer; George E. Sellers, Cincinnati, Ohio, January 10. The essential feature of this invention is, for working the hammer by means of two rollers, that receive motion from a steam engine, or other motive force, one of which has its bearings in permanent, and the other in movable boxes connected with a toggle-joint or other lever, so arranged as to force this roller towards the other, and gripe a square rod on the hammer to lift, and then separate them to liberate it-the toggle joint lever being connected with the roller by means of a powerful spring; and the mechanism that operates the toggle so arranged as to enable the attendant to regulate the play of the hammer at his discretion, to strike a light or heavy blow, as the condition of the iron may require.

Claim. "What I claim as new, is the manner of operating upon the lifting rod by means of the friction drums, one of which is made to advance to, and to recede therefrom, by being placed on a sliding frame which is operated upon by a toggle joint, under an arrangement of parts substantially the same with that herein described. I also claim the manner of arranging the respective levers, the catch, the cam wheels, and their appendages, so as to be operated upon by the lines and chains attached to the said levers, substantially as described.

"And I do hereby declare that I do not intend by these claims, to limit myself to the precise form and disposition of the respective parts of said machine, but to vary these as I may think proper, whilst I attain the same end by equivalent means.'

11. For an improvement in the Buckle for Connecting Straps; Kasson Frashure, Manlius, Onondaga county, New York, January 16.

This buckle fastens the straps together without a tongue, and is called by the patentee the "Angular Box and Grooved roller Buckle.' The lower plate, which is attached to one of the straps, forms with the upper one an angle, so that at one end they are nearer together than at the other; this constitutes what is termed in the specification the angular box. The upper surface of the lower plate of this box is grooved, and on it runs a grooved roller, the grooves of each fit
