IMPROVEMENT IN COTTON-PRESSES.

Specification forming part of Letters Patent No. 31,796, dated March 2G, 1861,

. To all whom, it may concern/f Around the center gudgeons of said nuts the Be it known that I, FERRY G. GARDrNnR,of rods N and N' are capable of turning. Rollers New York, in the county and State of New York, have invented a new and Improved CottonPress, and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure I represents a front elevation; Fig. II, a side `or end View; and Fig. III, `a plan with the cotton box and lower platen removed.

Similar lletters represent similar parts.

The nature of my invention consists in the arrangement v and construction of a cottonpress in which the lower platen is moved upward by means of levers operated by screws, said levers crossing and passing each other in their motion, and so arranged that the mechanism shall be contained within the space occupied by the frame work of the press, or nearly in a space equal to the required length of the cotton-bale.

In the accompanying drawings, A represents the frame of the machine or press, the upper part of which is closed on the four sides to form a box, B, in which the piston or lower platen, C, works, being guided by the sides forming this box, or said platen may be .provided with suitable friction-rollers attached to the under side of said platen. `Above the frame A a box, B', is arranged, forming a continuation of the box B, and constructed substantially in the manner and for the purpose as described in the patent granted. me on the Lith day of September, 1860. 4 The boltsG G, which secure the top platen or top of this box B', are continued downward, and are secured there to two strong bars, H H, which support the bottom pieces, J, ofthe frame, by which arrangement the two extreme ends, between which the strain is exerted, are firmly secured together by said bolts.

To the movable bottom platen, C, two

rods, NV and N, are attached by ymeans of bolts u and a, `in lugs provided in the center near the ends of said platen C. These rods N and N are bent in such a manner that while their top ends act upon the center line of the platen C their lower ends shall pass and be capable of crossing each other. To the lower endsof these rods nuts O and O' are attached.

P P are placed on these gudgeons m m', capable of turning freelyon the same and working upon suitable rails or ways, R R and R' R', fast on the frame J. These rollers l? and P' support the rods N and N', and take the perpendicular strain away from the screws S and S.

Upon the frame J screwsS and S' are placed parallel to each other and turning in suitable bearingsm; and w', fast to said frame J. These screws are connected together by wheels V and V', and the end of one screw `is provided with a wheel, WV, to communicate motion to the same, and which said motion will be communicated to the other screw through the wheels V and V', which gear into each other. A second wheel may likewise be placed upon the other screw, similar to the wheel W on the l other end of the machine, if it is desired to operate the press by hand-power.4 The nuts O and O' on the ends of the levers N and N are operated through these screws S S'.

The operation of the press is as follows: The nuts O and O' are brought by means of the screws S and S to the ends of said screws on opposite sides to each other, and so that the levers N and N' cross each other, through which operation,it will readily be understood, the upper ends of said rods,and consequently with the same the bottom platen, C, is moved downward, and said platen thereby brought into its lowest position. The boxes B and B are then filled with cotton, and the top platen, T, which forms the top of the box B', secured to the same by means ofthe bolts G G, whereby this top platen and thebottom frame, J, are firmly secured together. i

Motion is then communicated to the wheel W and screw S, and consequently through the y wheels V and V', to the screw S in such a direction as to move the nuts O and O', and with them the lower ends of the rodsN and N', toward and past each other until said rods N and N come in a perpendicular position, or ,y nearly so.

i n. ithat case provided with a right and a left handed screw-thread, each thread extending from the end until near the center ofthe screwshaft; but this arrangement and Construction requires thebottom bed or frame, J, at least twice the length of the length of a bale of. eotton, and Consequently nearly twice the length AI require by the above-mentioned arrangement and construction.

I am aware that levers arranged so as to Cross and pass each other while operating the lower platen of a press have been before used, and therefore do not claim thein'in and of themselves considered; but' NVhat I elailn as my invention, and desire to secure by Letters Patent, is-

The arrangement and combination of the right and left screws S S, pivoted nuts O O', and friction-rollers P P', resting on suitable ways,R R,attaehed to the frame J, when operating levers N NQ in the manner and for the purpose substantially as described and set forth.
