IMPROVEMENT IN GOTIII` NDEAY PRESS.

Be it known that I, WILLIAM DEERING, of Louisville, State of Kentucky, have invented a new Mode ot' Constructingr Presses for Compressing into Dales I'Iay, Cotton, or other Material; and I declare the following specification, with the drawings forming part thereof, to be a full and complete description of my invention.

Figure 1 represents a front view of the press with a portion removed to show the machinery within.

Figure 2., a perspective view of the press.

Similar letters denote the same parts of the apparatus.

A A is a strong oblong box, its two ends closed from top to bottom, the sides or fronts closed for about twothirds of the distaneefrom bottom to top, and the top and bottom are both-open. Along its sides and at its bottom it is strengthened by stout'clamps or cheeks of plank B B, which project beyond the ends of the bon inv order to carry a portion-of the machinery for operating the press, hereafter described. At the top of the closed part of the sides the box is also strengthened by stout clamps C C, cross-tied by end ones D D. That part of the box E which is open above C is to be closed with strong doors, (not represented in the drawings, 'not being necessary to explain the working of the machina) opening downwards, being-hinged on pivots passing through sockets a a in D D. ,The box is covered, when the machine is worked, with a platen, so-called, formed of wooden bars Z) b, with spaces between them, in the usual way in which they are made for such presses, for the purpose of passing the ties by which thc bales ol' hay or cotton are secured' after they are compressed. These bars are attached to a pair of parallel bars, G, above them, placed a little distance apart and projecting lover each end of the box in order to carry there a pair of pulleys or sheaves, ee. A movable platen, also constructcd of bars in the usual way, is fitted to the interior of thc box to-movo upward and downward within it, with arms H projecting beyond the ends of the box through a slot, J, fitted for their passage from the bottom to the top of the enclosed part of the box. To cach arm II is attached a singlesheaved block, j'. The motivevpower Ais at each en d of the machine, and is constituted ofa shaft, S, ttcd to revolve horizontally between and through the cheelis B 13. Upon this shaft is fixed a conical barrel, K, with increasing volute channels to carry a rope-or chain, similar to"the fusee of a watch with its chain; also a ratchetwhecl, L. This' ratchet is worked by a lever, M, with its pawl N arranged in the usual manner. A chcck-pawl, 1L, shown in iig. 1, is fitted vto the frame of the machine. A rope or chain, I, fastened to the end of the largest volute of K passes upward and overone of the sheaves at e, thence downward to and around the sheave utf, thence upward and around the other sheave of e, and then downward and secured to the strap of bloolij". This is donc whilst the lower platen is at the bottom of the box, the dimensions of the fasce-barrel K being so proportioned that when thc rope P shall occupy all'its volutes the platen shall arrive at C C, or the top of thc closed part of the box. In order to 4insure the accurate working of the rope upon the fasce, that volute upon which it is being wound should be opposite the centre of the arm N. This is done by forming one end, Si, of the shaft S into a screw, with threads of a proper pitch to advance the shaft at the proper rate to produce the desired clfect, and making a female thread fitting` the screw within B. In .order to iill the box with material from the top it is necessary to remove the upper platen to one side. For this purpose the arms R R are placed projecting i'roni the top of the box, so ns to receive the platen when it is so moved to uncover the box.

To operate thc machine, close and secure the doors, move the upper platen to one side, place the movable ,platen at the bottom of the box, put the hay o r cotton into the bou, replace the upper platen, then, bythe levers M, revolve the shafts, raising thc lower platen until it reaches the top of its course, then in the usual way secure the compressed material into a bale, open the doors, and remove thc'bal'e. The operation and effect of the volute barrel K is this: The larger volutes exert less power upon the rope or chain, and consequently upon the moving platen, than the lesser ones, in reference to the motive-power applied to the levers M; consequently, as the rope winds `from the larger to the lesser volutes, the pressure of the platen upon the material pressed increases as it ascends in the inverse ratio of the distance of the rope from the axis of theshaft S, so that in machines-of moderate dimensions, arranged as shown, the pressure ofthe platen upon the bale, when completed, may be six to eight timesI greater than when it started on its course. By increasing the number of sheaves (for I do not limit myself to thenumber described) and the proportions ofthe volute barrel accordingly, the relative pressure may be increased to any required extent.`

The arrangemerrt by which the upper platen, although removable, is during the operation of the machine immovable, and the lower platen moves to effect the pressing, is an importent feature in this press. In other presses, where the upper platen is the movable one, the removing ofthe seine between each charge of the box, and necessarily disconnecting it from the working power, is a. source of great delay and trouble. By my arrangement a. slight slnckening of the rope permits the platen to be removed without inconvenience or mnterial delay.

What I claim as my invention, and desireV to secure by Letters Patent, isl. The shaft S, with tbc fusee-berrel K, in combination with the rope P and sheaves e andf, and the lower platen H, arranged :incl proportioned/in the manner and for the purpose described.

2. The screw terminal S2 u on the shaft S iittedinto a. female screw withiniB, in the manner and for the.

purpose described.

3. The arrangement of the plctens, by which, When operating, the upper one is stationary and the lower one movable, inY the manner nndfor the purpose described.

4. The combination of the lever M with its ratcllets and pawls, slraft S, fusee barrel K, screw S2, rope P, shea-ves e andf, upper :ind lowci` platens, :rnd box A, in the mnnner :und for tbe purposes described.
