IMPROVEMENT IN COTTON-PRESSES.

fipeciiication forming part of Letters Patent No. 204,240, dated May 28", 1878, application filed 4 November 12,1877, V I

To all whom it may concern:

Be itknown that I, EDMUND L. MoRsE,' of the city of N ew Orleans, in the State of' Louisiana, have invented a certain new and useful Improvement in gotten-Compressors, of which" the following is a full, clear, and exact devalve in the cylinder-head, which is closed by a spring and opened by a weight, the weight having the preponderance, the arrangement being such that when the piston in its ascent reaches the weight it lifts the weight with it, and then the valve closes, and an air-cushion is formed in the upper part of the cylinder.

In the drawings, Figure 1 shows the press, one half in front elevation and the other half in axial section, the piston being down. Fig. 2 is an enlarged view of the piston, half in side view and half in axial section, (piston up.) Fig. 3 is a transverse section of the platens.

Theiiframe may be of iron or timber. In the illustration it is shown with wooden posts A, surmounted by an iron frame, B, connecting the posts together at top, and supporting the cylinder. 0 is a central iron frame attached to the posts or uprights A, and supporting the upper and fixed platen D and the cog-sectors E. The cog-sectors are connected by four rods, F, to the lower or moving platen G. I A is the foundation, having a cavity to receive the lower platen Gr when in its lower position. At A are shown four vertical posts or uprights, connected together at top by crossbeams A and the iron frame B. Upon the central frame C- are pillow-blocks H, in which are supported the fulcrum-wrists I of the cogsectors E. J is a bar passing transversely through each cog sector, and whose ends form wrist-pins j, passing through the' upper endsof the lifting-rods F. Of ,these rods F there are four-two toj each 'sectorand their lower ends are connected to the fourcornersjof the lower platen G by wrist-pins g.

The 1ower platen G has guide-lugs 9 working with increased power upon the lower platen K K are cog-racks attached to the lower end of the piston-rod L, said racks engaging with the cog-sectors upon the opposite sides.

It will be seen that cog-racks must be inclined so as to approach each other as they extend downwardly, so as'to suit them to the cog-sectors, whose cogged faces approach each other as they turn upward. The lower end of the piston-rod L works between suitable guides.

M is the piston working in the cylinder N. In ordinary working, thesteam is only admitted beneath the piston, to lift it, and the descent of the piston is accomplished by its own weight and that of the parts attached to it.

0 is the steam-port, through which steam is admitted to and exhausted from the cylinder, the movements of the steam being governed by any suitable valve or valves operated by hand; or the valves may be operated in part by connection with the moving parts, so as to stop the movement of the platen G on its reaching its upper and lower positions, respectively.

P is a U-formed pipe, whose ends communicate with the inside of the cylinder at two different elevations, near the upper end of the' cylinder. The distance of the pipe-openings apart is at least as great as the thickness of the piston, so that when the piston has reached such an altitude as to pass the mouth 12 and expose it for the entrance of steam from the part of the cylinder beneath the piston, the steam passes through the pipe P into the part of the cylinder above the piston, and thus the further ascent of the piston is prevented.

In the pipe P is a ball or other valve, Q, which prevents retrograde or down ward movement of steam or air through pipe P. In the head a of the cylinder is an inwardly-opening valve, R; and S is a spring, tending to close the valve and prevent the escape of air or steam when the piston is near its upper posidown, giving the outer air entrance into/the top of the cylinder and allowing the piston free descent.

I prefer to connect with the upper partof the cylinder a steam-pipe with a valve, by which steam may be admitted above the piston, to force it down, if it any time it may be found necessary. and it will be seen that at such time the ball-valveQ would come into action, preventing the escape of steam into the space beneath the piston when the piston is in its upper position.

The faces of the platens at the sides (1 and d incline outwardly from the plane of the flat central part d of the faces, as shown in Fig. 3, to give a flattened corner to the sides of the bale, thus imparting to it about the form in which it is retained by the hoops after removal from the press, and enabling the use of somewhat shorter hoops, and consequently diminished size of bale with the same pressure, because the expansion of the bale is less after removal from the press.

I claim as my invention- 1. The combination of cycloidal cog-sectors E and inclined cog-racks K, substantially as and for the purpose set forth.

2. The combination of cylinder N, piston M, and valve It with closing-spring S and suspended weight V, substantially as set forth.

EDMUND L. MORSE.
