IMPROVEMENT IN COTTON AND HAY PRESSES.

Specification forming part of Letters Patent No. 3,288, dated September 28, 1843.

o a/ZZ whom. it may concern..-

Beit known that I, WILLIAM BULLocK, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Press for Pressing of Hay, Cotton, &c.; and I do hereby declare that the following is a fulland eXact description.

The nature of my invention consists in procuring an immense power for pressing by the combined mechanical arrangement of com` pound levers and toggle-joint, in combination with the ordinary block and tackle, which I term my compound lever and toggle-joint press, as is fully set forth in the accompany ing drawings and following description.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction andoperation.

I construct my press, as per drawings, Figures l and 2, with four main posts or standards, A A A A, about ten inches square and eighteen feet long, being held together by cross-fram` ing B By B B,mortised in the upright standards at'various heights. Vithin this main frame is a trunk or box, C C C C, which is about ten feet deep, the inside area being to the detertop of the press (marked D D) is a head-beam, which slides in the under side of the two crosspicces E E, said head-beam being for the purpose of receiving the whole pressure or strain of the press in an upward direction when theV bail is pressing.

rIhe manipulation of' working the press is as follows: You first take out the beam D D, and then turn down the two sides F F and G G, which work on 'a hinge. Your press is then ready to receive the cotton in the trunk or boX, and when full turn up again the sides and ends F F and G G, and lock them by means of the lock-pieces H H, and replace the head-beam D D. rIhe cotton is then ready for pressing, which is operated upon by the follower I I, the said follower receiving its power by the combined action of the block and tackle .I J and the compound levers and'toggle-joint K K and L L, the follower I I, being fastened to the upper end of the lever K K by means of a swivel-joint, M, and on the lower end to a swivel-blockand sheaves, N N, the lever L working on a fulcrum, O, which rests in the center ofthe running-beam P, and working at the other end by means of a center pin in the center of the lever K K. Now, it will be readily seen that by. pulling on the rope Q you will have the mechanical power of the block and tackle which draws the lever K inward, which, with the combined connection of the lever L L, having a working center at It, and resting on the fulcrum O, forms a` compound lever, which vI shall term my compound lever and toggle-joint,77 so that the power of the press increases as the follower gets near the top, which is just what is necessary for cotton or hay. l

Thepress may be worked by power or hand, and may be much increased in power by working the rope over a small windlass; or instead ot' working by block and tackle may use a screw, as is shown in Fig. 3. mined size of a bail of cotton or hay. At the What I claim as new in the above-described f press, and desire to secure by Letters Patent,

rIlhe above-described method of constructing a press-that is to say, a press in which is operated a single toggle-joint-by means of an arm which is extended beyond the movable fulcrum of the joint, to the end of which arm the power is applied so as to act in a direction at right angles to the line lin which the follower moves, the application of the power be ing made through thel medium of pulleys `or other analogous device, substantially in the manner and for the purpose set forth.
