JAMES S. PRICE, OF SAME PLACE.

COTTON-PRESS.

SPECIFICATION forming part of Letters Patent No. 502,313, dated August 1, 1893.

Application filed June 30, 1892- Serial No. $38,499. (No model.)

To all whom it may concern:

Be it known that I, JOSHUA L. Mo CUTOHEON, of Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Cotton-Presses, of which the following is a specification.

My invention relates to cotton-presses and has particular reference to that class in which the cotton, either in the form of a continuous folded bat or otherwise, may be pressed between a stationary and a steam or hydraulic power operated platen.

My objects are to combine in one press the advantages of the quick but not extremely powerful pressure of the ordinary steam press,

and the powerful but slow pressure of the hydraulic press; and to this end, my invention consists in the construction and combination tion, illustrating a slightlymodified form of support for the swinging blocks. Figs. 3 and 4 are on a slightly larger scale than the other Similar letters of reference in the several views indicate the same parts.

The frame of the press includes the fixed uprights or standards R R, the timbers F and connecting plate D at the upper end, and the timbers "S S at the lower end. Above the frame and held vertically thereon by stays B, is secured a steam cylinder A, the lower flange O of which is bolted to the plate D. The lower end of the piston E is connected to a follower G which, in turn is connected to the platen H, by any suitable means.

L represents the lower platen bolted on the flange or head M of the hydraulic ram N, working in a cylinder Q, the upper end of which has flanges O P through which bolts pass for securing the cylinder and ram to the timbers S.

The distance between the two cylinders A and Q and consequently between the normal positions of the two platens may be somewhat thereon, and which support strong blocks or struts I, the purpose of which will presently be explained. 7

Instead of the tubes K, I may employ a pair of strap arms as shown at J in Fig. 4..

The operation is as followsThe two platens being in the position shown in Fig. 1,the cotton to be pressed is placed between them and steam is admitted to the cylinder A to depress theplaten H and thus partially depress the charge of cotton. When the platen H has been depressed to the proper extent, the blocks I I are swung around until they are interposed between the timbersF and the upper surface of the platen H each side of the follower G, and are then in position to firmly support the said platen against the powerful upward pressure of the hydraulic ram which is then operated to complete the compression of the cotton for baling.

'Having now described my invention, what I claim, and desire to secure by Letters Patout, isi 1. In a cotton press, the combination with the frame, of two platens independently movable toward each other to compress the material between their faces, motors separate and independent from each other for operating said platens, and blocks or struts adapted to beinterposed between portions of the-frame and the back of one of the platens, for the purpose set forth.

2. In a cotton press, the combination with the frame, of two platens independently movable toward each other,a motor for each platen, one of which is adapted to impart a quick but light pressure, and the other a slow but powerful pressure, the two motors being onward over the upper platen and rest with their lower ends on said platen and their upper ends against a portion of the frame, substan- I 5 tially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 20th day of June, A. D. 1892.

JOSHUA L. MCCUTOI-IEON. Witnesses:

'l. O. BAIRD, Z. O. LAW.
