Specification of Letters Patent No. 812, dated June 27, 1838.

To all whom'z't may concern:

Be it known that I, (JrEo. C. CHEsLEY, of Rockymount, in the county of Franklin and State of Virginia, have invented a new and useful. machine for pressing tobacco, cotton, oil, sugar, &c., or for crushing plaster or crushing and pressing apples or any other substance requiring hard or moderate pressure by hand, steam, water, horse, or any other power equal thereto.

The construction of my invention is such, that by combination of lever power, in the common lever in length and strength, and the power of the screw and wedge I can press from one to any given number of hogsheads or boxes of tobacco, bales of cotton, &c., by hand, steam, horse, water or any other power equal thereto.

The frame consists of grooved uprights C, one sill A, one girder D, and as many cross sills B and top girders E (the one answering to the other) as there shall be drivers or stems M. Then there is a beam F running parallel wit-h the sill A and with the girder D, thick or large in the middle, tapering to the end to any size required.

This beam F has connected with it by ligature or hinge N, N an arm or arms Y, which are shouldered with tenon and which play up and down in the grooves. Then to these arms are connected, a driver or stem, or drivers or stems M, which are forced perpendicularly true, upon the substance, while the beam F moves obliquely from end to end alternately. Then the beam, carrying the arms and drivers, is worked by hand power a lever is applied to each end of the beam with a loose band to be thrown off or on as the pressure shall require, or for dispatch. WVhen quick operation is required, the band is to be thrown on; but when hard pressure is needed, the band is thrown off, and theend of the lever is made fast by means of a pin in the sword H, the lever resting upon the end of the beam F, yet made fast by means of a ligature or hinge N. On the application of hand power, the swords H, which are planted in the ground, may be used, together with the wheel, crank, and

endless chain,v or in any of theknown ways, or means, by which hand power may be applied. Screw power may also beapplied, by fronting the frame of mymodel with the frame of a screw,with the screw in its frame, and by placing the si l A into the screw frame and so applying screw power on each end of the beam, alternately, and by fastening the screw with the end of the beam, the beam may be screwed up or let down one end at a time, yet thearms and drivers are carried perpendicularly true.

When this machine is worked by horse, steam, or water power, then a crank is used at each end of the beam, so as to play the beam obllquely, or from end to end, while the arms and drivers are carried perpendicularly true.

The whole machine, with or without swords standing in house or field, may be made of wood, iron, or any other material, of any size, the frame, beam or beams, driver or drivers of any length, strength, width,

breadth, height, &c., and any given lever power, whether in lever, commonly so called,

that is in length and strength, whether in screw or wedge, may be applied to the beam,

arms drivers or stems, the beam moving ob-x liquely, while thearms and drivers or stems, with or without fixtures at the bottom for crushing and pressing, must go. perpendicu larly true, to affect the substance placed thereunder. WVhen the frame is widened, so that two or more beams, carrying the arms and drivers, or stems, can be admitted, by

placing the beam to play obliquely, parallel with the sill and top girder, then theends of the beams are yoked together witha beam, bar, or rod, made of any material, and the lever connected withthe beam, by band or otherwise, is placed in the center of the beams, if only two beams inthe frame, on

or across the yoke; the yoke being fastened to the lever, and yet the yoke lies in a rolling position, across the end of the beams while the lever, thus fixed at each endof the beams, can be worked as before described;

or if there" be three beams, then the lever is placed across the yoke, immediately at the end of the center beam, yet so fastened to the i beam and yoke with ligature or hinge, made of any material, as to bind the yoke and lever together, while theyoke lies in a r011 1 ing position, across the end of the beams v Geo/"j 0. 0665/07.
