Specification of Letters Patent.

Application filed November 27, 1900. Serial No- 37,905.

Patented Sept. 10, 1907.

To all whom it may concern:

Be it known that I, SAMUEL J. WEBB, a citizen of the United States, residing at Minden, in the parish of Webster and State of Louisiana, have invented certain new and useful Improvements-in. Compresses, of which the following is a specification.

My invention relates to cotton compresses and has for its object to improve such compresses and more especially to provide such compresses with side plates cooperating with the platensbetween which the bale iscompressed, and to these ends it consists in the various features of construction and combinations of parts substantially as hereinafter more particularly set forth.

Referring to the accompanying drawings: Figure 1 is a side elevation of a compress embodying my invention; Fig. 2 is a vertical transverse section of the construction shown in Fig. 1; Fig. 3- is an enlarged section showing the platens and a portion'of the mechanism for operating them-and another arrangement of devices for operating the side plates; Fig. 4 is a horizontal cross-section of Fig. 3 on the line of the floor, showing one of the plates removed and the other in position; and Fig. 5 is a detail view showing automatic means for controlling the operation of the supply valve for operating the side plates.

My improvement embodies platens for compressing the bale, one of which is movable and which is shown as being operated by a lever mechanism, which mechanism is operated from a steam cylinder, and there are represent posts composing the main flame of the com- I press, mounted on a suitable base,,A, and secured to theseposts is a main frame portion, A This base and frame portion may be differently constructed but are preferably so arranged as to support or carry the fixed platen, B, and to support a cylinder, D. This cylinder, D, is provided with a piston, D, the pistonrod, D of which is provided with a cross-head, D to which are connected links, D which in turn are connected to the swinging levers, D pivotally mounted on the frame, A, at the point, D. Also connected to the linlis, D, are links, I), attached to the frame, A or the platen, B, attached thereto. levers, D are also connected to a pin or bearing, D, on which are also pivoted the lifting rods, D pivotally connected to the lower platen, C. The upward movement of the piston,'D in the cylinder, D, is

controlled by a valve, d, in the inlet pipe, d, and this valve is controlled by a com, d, on a rod, 01 operated by a link, d, connected to the rocking handle, d

The exhaust is controlled by a similar valve operated by the cam, d, on the-rod, d

When steam is admitted to the cylinder, D, the pis- The-links, D and ton is raised and through the lever and link connections before described the lower platen. G, is moved upward under great power to compress the cotton in a manner which is well understood, and it is lowered at the proper time by exhausting the steam. from under the piston.

Arranged in proper position to cooperate with the compressing platens and mounted on some separate part of the press, and as best shown in Fig. 2, the crosspieces, A of the frame, are side plates, E, E, and these plates are arranged so as to normally lie in substantially the positions indicated in Fig.2 and to be moved up-- .ward to assume the positions substantially as indicated in dotted lines in Fig. 3, and'while variousmeans may be used for operating these plates I have shown a toggle mechanism and engines, F, F.

The toggle levers, E, E, are connected together at the point, E and one of the toggle levers, as E, is connected to one of the plates at or near its free end,- while the other toggle lever, E is connected to a fixed rod, E, which is supported in any suitable way, and in the present instance by means of tie-rods, E E, and this rod, E is locate'd in a position a-tor nearthe floor line of the building in which the compress is erected. I

Connected to the middle point or point of connection, E are lifting rods, E, which in tiun are connected to the cross-heads, E of the piston-rods, E connected to the pistons, F, of the engines, F. I also preferably provide guide rods, E for the cross-heads, E, which guide rods are secured to the frame of the compress and to the engines, F, F.

Each piston, F, is provided with a projection, f, on each side adapted to enter a recess, f, in the cylinder heads of the engine to form a cushion for the piston at the end of its movement in each direction.

The engines, F, are supplied with steam in any suitable way, but I have shown a pipe, f connected to the steam pipe d, and also connected to the recessed portions, f, of the cylinder heads so that steam is admitted to the cylinder through the recesses, f. A by-pass'pipe, f connects the pipe, f directly with the cylinder between the face of the piston and the cylinder head and this is provided with a suitable check valve, f

which permits the steam to enter the cylinder through i the by -pass pipe, but prevents its return.

A suitable valve, f controls the inlet of steam through the pipe, f and its branches to one or the other end of the cylinder, and also controls the exhaust through these branches and through an exhaust outlet, f and this valve may be operated in any suitable way, as by the rod, f connected to the lever, f.

It is desirable that both side plates, E, E, should be operated in unison and simultaneously, and in order that this may be done I have shown ashaft, F mounted on the fixed platen to which are attached arms, F

, pinions are operated by a rack bar, I. This rack barconnected by links, F, to the cross-heads, E of the pistons, and in this way thesha ft, F is rocked when the plates are operated and their simultaneous and uniform operation is insured. I

While the apparatus so far described is one .which has proved efficient in actual practice, I will now describe another means for operating the side plates which has also proved satisfactory and which has been used in connection with lever mechanism for operating the main platen shown in Figs. 1 and 2, and consequently in Figs. 3 and 4 I have not shown the whole of the lever mechanism but only the attachments connected with the compress for operatingthe side plates. -In this construction the side plates, E, E, instead of being. mounted on cross-pieces, A, are mounted on cross-pieces A, of the frame, which cross-pieces, A, rest directly on the posts, A, A being metallic foundation plates properly so called for the press, and A being preferably masonry or some similar base material. To the foundation plates, A, are attached hinge sections, e, which are shown in the form of plates secured to the foundation plates and having projections, e, supporting the rod or-pintle, e of the hinge. The under sides of the plates, E, are provided with ribs, e", having openings to receive the pintle, e", and the inner edges of the faces of. the plates are curved downward at e, to cover the facesof the projections, e The sides 0, c, of the movable platen, C, are provided with finished portions which bear against the faces of the plates, E, which.

thus serve to guidethe platen and support the side plates. Additional guides for the platen; G, are also preferably provided. Thus to the posts, A, are secured the foundation plates, A, and to these plates is secured foundation plates'to hold theguide in position. The

.pins, 1), by means'of which the liftingrods, D are secured to the platen, 'G, are provided with projections, 0. which aid in securing the guide shoes, a, to the pins, and these guide shoes tend to prevent the movement of the lower platen sidewise or lengthwise. Any other suitable arrangement of guides-can be used. In this construction the means for operating the toggle levers, E, E differs from that shown in Figs. 1 and 2. In this case the segments, G, G, are attached to the point of connection, E of the toggle levers, and are also detachably connected to the lever, E, by braces G, G.

These segments are provided with teeth, 9, which are engaged by the teeth of pinions, H, H. These pinions are, respectively, mounted on shafts, h, h, attached by brackets to the foundation plates, A, or are otherwise suitably supported. On these shafts, h, h, atone side of the compress are mounted pinions, H H and these reciprocates in a frame, I, which has bearings for the shafts, h, h, and is arranged at one side of the compress. This frame, I, isconnected to a cylinder, F which is mounted on a proper foundation, A In this cylinder, F reciprocates a piston, F and to this piston isattached the piston-rod, F which in turn is attached to the rack bar I. This cylinder, F is constructed substantially like the engines, F, F, of Figs. land 2, and need be specifically described, the corresponding parts being correspondingly lettered, and it is provided with cushions and operating valves as before set forth. The

pinions, H H, are arranged on opposite sides of the rack bar, I, so that when the rack bar moves in either direction the segments, G, will move in unison therewith and operate the side plates simultaneously. The tie rods, E, connecting the rods, E, are, as shown, bent to embrace the posts, A, and foundation plates, A, and are secured in any suitable way so as to prevent longi tudinal movement and maintain the rods, E, in proper relations to the platens. It will be seen, more especially with, reference to Fig. 4, that the toggle levers, E are inclined toward the center of the compress, and I preferably arrange a distance piece, E betweentheir inner ends to relieve strain on the side of the hinge, and the other ends of the toggle levers, E, are preferably held together, as by a bolt, E.

The compress is generally arranged so that the upper faces of the'side plates, E, are practically in line with the floor, I, of the building v in which the compress'is situated, and from and to which the bales are received and delivered in their passage through the compress. In practice I provide a moving platform, K, which bridges the space between the floor, J, and the outer ends of the side plates when they are down, and this platform is preferably connected to the rods, E, so as to turn or rock thereon, and the other end is supported on the toggle levers, E connected as by posts, k. It will be seen that with this construction when the side plates are raised to the positions shown in Fig. 3, the toggle levers, E, E ,are in the positions shown in dotted lines and are practically straight and form locks for the side plates, andat the same time the platform, K, is raised, and it serves as a means of heading the bale, that is, of tilting on end ready to be received by fthe truckers and conveyed to its destination. glllde, a, and lugs, a, are preferably provided .on the In order to prevent the operation of the side plates while the bale is being placed in position between'the main platens or being banded or otherwise and thus prevent accidents to the operators, I provide automatic means lwhichwill prevent the side plates from being lifted into their upper positions. Various means may be provided for this purpose. Thus referring to Fig. l I connect the operating lever, f with a pivoted bar, f, which may be suitably mounted in relation to the lower platen, C, andthis bar is connected to the operating lever, f, by a link, f 9, or otherwise. When the lower platen, C, is in its elevated position, the end of the platen adjacent to the bar, f will prevent it from being moved inward, which movement of the operating lever, f is necessary to open the supply valve, f to the engines, F, and it will thus be seen that the upward or downward movement of the main platen, C, forms an automatic lock to prevent or allow the movement of the operating lever, f", in such a direction as to cause the side plates, E, to be raised, and it will be seen that it is impossible to so operate the lever when the platen is in its raised or compressing position. Additional safety devicesor independent means for locking the operating lever, f may be provided, as

tion, and hence control the operating lever, f This independent mechanism may operate at any time to prevent the operation of the side plates, but it is intended more especially to lock the operating lever, f

when the bale is being placed in position or removed from the compress. Another automatic meansior preventing accidents is shown in the pressure regulating valve, M, Fig-1, connected to the pipe, supplying steam to the engines, F. This valve is an ordinary pressure regulating valve arranged inthe pipe 1',

and connected by a pipe, m, near the lower end of the cylinder, D, just above the piston D, when it is in its lowest position. As soon as the piston passesthe opening of this pipe, m, in the cylinder in its upward movement steam passes into the pipe and operates the pressure regulator to close its valve and prevent steam from-passing through the pipe, f and whenthe piston descends to its lowest position the steam in the pipe, m,

exhausts into the cylinder, D, above thepiston and the pressure regulator is relieved, allowing the steam to flow through the pipe, f and the engines,- F, tobe operated'by the operator.

In Fig. 5 I have .shown the automatic means, including the bar, f*, as arranged above the rack bar frame I, and in. this arrangement the bar, is .connected directly to the .stemof the valve f which is extended along the side of the compress ior this purpose.

in compressing "cotton; or other material will'be readily understood, and it willbe seen that the bale-is placed upon the movable platen,.C, in any suitable way, and

the side plates are thenoperated in the manner hereinbefore described so that they assume the; positionsshown in dotted-lilies, displacing the cotton. so as to narrow the baleto the proper width. In case/the bale is narrower than the width of the movable platen the side plates act-only as confining plates, confining the baleagainst expansion while it is being compressed;

between the stationary bed and movable platen. It will thus be observed that the operating faceof the platen, C, is narrower than'the operating face of the ordinary platen s'oi a compress, and in compressing bales if they are wider than the width of the operating face of'the movable platen" the material of the bale is displacedto narrowthe bale, so as to reduce the area of the surfaces exposed to the compressing platens.
