UNrTnn STATES M. D. CHEEK, OF MEMPHIS, TENNESSEE.
IMPROVEMENT IN PRESSES.
Speciiication forming part of Letters Patent No. 5,597, dated May 23, 1848.
To @ZZ whom, it may concern.-
Beit known that I, MosEs Ducarme (lumix, of Memphis, in the county of Shelby and State of Tennessee, have invented a new and useful Improvement in Machinery for Pressing Hay and Cotton, and for other purposes, which I denominate the Portable Sampson Press,77 of which the following is a full, clear, and exact description, reference being had to the annexed drawings of the same, making part of this specification, in which- Figure I isa perspective view showing the several parts in connection. Fig. 2 is a view of the levers detached. Fig. 3 is a View ofthe face of a pair of the j oint-bloeks.
The same letters indicate the same parts in all the figures.
In thev accompanying drawings, the framework a of the machine is made of timber of suitable dimensions, and substantially framed together. The four posts a a a c have grooves b on their inner sides, in which corresponding tongues, d, which project from the sides of the piston-rods c, slide, in order to guide the piston @steadily in its ascent and descent. The press-box is not shown in the drawings, and, being a common contrivance admitting of almost endless modifications, I -do not deem it necessary to refer to it any further than to say that it may be made of the form best adapted to the purpose for which it is designed tc be On the adjacent sides ofthe piston-rods the double ratehets f f are secured, the teeth m of these ratchets being opposite to the space between the teeth n. The teeth of both the ratchets are equidistant, the spaces between them being equal to the length of the vertical` motion of the ratchets or toggle-joint levers o o. The lower levers, p p, are connected together at the top by a castiron cap or tie, lr, on the upper side of which the lower half, s s, of the toggle-j oints are formed, which are con- Vex in their shape, having cogs on each end. The bearing s', on which the lower ends of the levers p rest, is made of cast-iron of a rounded or convex form, with cogs also on each end, is let into the surface ofthe base of the frame. The lower ends of the levers p j) are made to fit into a cast-iron socket, t', having its under surface plane, of arectangular form in area, corresponding nearly with the convex or cylindrical surface of the lower half of the joint s, and having also cogs which gear into the cogs of the lower or convex half of the j oint,to keep the parts respectively in their proper places. rlhe ratchets or upper levers, o o, are formed with the upper half, e o, of the toggle-joint on their lowerends. These j oint-pieces are flat, and rest upon the convex surface of the lower halves, ss, and have cogs on their ends, which take into the cogs on the ends of the parts s s,
to hold them together. The upper ends of these levers are armed with' cast-iron beaks, of the form in which pawls and ratchets are usually made, and are of a size which renders them linto the vertical position, where the points of support and resistance are at their greatest distance apart, the deflected lever 0 takes into a notch in the ratch next below the one it last raised, and while these deiected levers are forced back again into the vertical position the opposite levers are bent out until the ratchet takes into the ratch one notch lower than it did before. In this way the levers alternately advance the piston until it is moved forward, so as to produce the required amount of compression. It will be seen that the action oi' these levers differs from that of other togglejoint levers only in the rolling of the joints against, instead of sliding, upon. the surface of each other. rIhis rolling is caused by one-half of the joint being convex and the other flat, instead of making one concave and the other convex, and iitting them together accurately, as is the usual method, when they must necessarily slide upon each other, and when, unless they be fitted and polished at great expense, a great deal of power will be absorbed by friction; but my rolling joints may be made of cast-iron and put together just as they come out of the constructing the joints in this manner the effi l ciency of the press is increased, while its cost is materially diminished. The levers are vibrated by a pitman, t, alternated by a crank, which is putin motion by any suitable come bination'of Wheels, pulleys, and axles, the The combination of the plane and convex Whole being moved by manual, horse, steam, cogged blocks o s and t s, with the levers o 19, or other power. The Weights y are for the purto form a rolling toggle-j oint, as herein set fort-h.
