COTTON-PRESS.

SPECIFICATION forming part of Letters Patent No. 498,052, dated May 23, 1893.

Application filed October 5, 1892. Serial No. 447,910. (No model.)

To aZZ whom it may concern:

Be it known that I, FREDERICK GARRAUX, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and use- .ful Improvements in Cotton-Presses, of which the following is a specification.

My invention more especially relates to that class of cotton presses in which a pair of baling chambers or boxes are pivotally supported on a central post or standard and are adapted hereinafter set forth.

The object of one part of my invention is to improve the operating mechanism of the tramper, whereby it may act more efficiently, more rapidly and with increased power.

Another object is to construct the upper part of the bale box or chamber in such manner that it may more quickly and more easily be opened and closed, more securely locked and more expeditiously unlocked.

A further object of my invention is to provide improved means for supporting the follower when separated from the plunger, and novel devices for locking the follower to the plunger when they are operating together.

Further objects of myinvention are to provide improved means for starting and stop ping the plunger, and novel devices for preventing the engagement or entanglement of the cloth covering of the bale between the plunger and the follower.

My improvements are shown in the accom panying drawings embodied in a cotton press of a well-known class.

Some of my improvements may be used in cotton presses of other classes,and indeed in many classes of presses not specially designed for packing cotton. v Unless otherwise specified, the mechanism is of usual well known construction.

Figure 1 shows a front elevation of my press. Fig. 2 is a side elevation thereof. The remaining views are on an enlarged scale. Fig. 3 is a transverse section on the line'3-3 of Figs. 1 and 2. Fig. 4 is adetail View, partly in transverse section, of the tramper-operating mechanism. Fig. 5 is a vertical section of the same mechanism. Fig. 6 is a detail closing and locking the sides or doors thereof. Fig. 10 is a front elevation of one end of one of the boxes; and Fig. 11 is an end view thereof.

A central supporting post or column A, is securely fastened to a foundation B, made of strong beams or timbers b,in any suitable way. The standard extends through the floor C, of the gin house, and carries a circular platform D, which is on a level with, and

really constitutes a continuation of, the gin floor, but is separated therefrom and is pivoted on the standard so as to be able to revolve thereon. At the top of the standard is securely fastened a heavy frame E, composed of stout timbers e, and carrying the head block F, of the press. Vertical rods G, extend from the head block frame to the foundation frame, and in connection with the center post securely hold the head block frame against all strains. g

The tramper frame H, is constructed in any preferred way, suitable to support the oper ating mechanism of the tramper. As shown, vertical timbers it, rise from the inner end of the head block frame, and support at their upper ends the cross pieces h, which at their opposite ends are secured to the posts 7?, rising from the gin floor. A rod h also secured to the gin floor, is fixed to the tramper frame, and serves to tie it in place and hold it against vertical strain when the tramper is in operation.

The baling chambers or boxes I, are similar in construction, and extend through the circular platform D. The beams i,at the lower ends of the boxes are securely fastened and tied together, and diagonal or inclined braces 11, and i on opposite sides of the center post, connect these braces with the platform. Rollers d, secured on diametrically opposite sides of the platform are adapted to alternately bear on the bracket 0, of the gin floor. One of the rollers is shown in Fig. 1, as hearing on this bracket, and when in this position, the platform is supported and strengthened while the tramper is operating. The roller on the opposite side is not supported, as the platform on this side is not subjected to a downward strain. Over each roller, is a notched plate K, with which a foot lever K, on the gin floor, is adapted to engage. Only one such foot lever or latch is employed, and this engages with the notched plate on the left-hand side of the press, as shown in Fig. 1, and when thus engaged, there is always a baling chamber under the 'tramper and one over the plunger. Thelatch automatically engages with a notched plate when the bale boxes are swung around, and the operator may, by putting his foot on the end of the lever, release the latch and then by giving the boxes a push and taking his foot from the latch, the position of the two baling boxes or chambers may be reversed.

The baling chambers are open at top and bottom, as usual, and each has a follower or platen L, constructed in the usual way, and

adapted to move from top to bottom 'of ,the press. When not engaged by the plunger, the follower is supported by brackets Z, secured to the under sides of the bottoms of the bale boxes and projecting a short distance inwardly beneath the follower, as clearly shown. Preferably, Iemploy four such brackets under each baling chamber. a

In order that the edges of the cloth bale, cover, or bagging usually employed, may not become entangled with the plunger, I provide catches or hooks M, at the bottom of each press, which receive the edges of the cloth, and prevent its hanging down below the'bottom of the follower. Four such hooks or catches for each baling chamber will be su fficient and they may be located on opposite sides at the ends of the boxes, as indicated in Figs. 1 and 2.

The plunger N, is supported in the foundation framing B, and is adapted to be moved vertically by suitable mechanism. The plunger proper may be constructed of suitable strong and stout timbers n, and it is connected with a screw 0, carrying a nut 0, provided with gear teeth 0, meshing with a pinion p, on a driving shaft P. This driving shaft is mounted in suitable bearings and carries two pulleys P, P both of which may be belted to any suitable prime mover. The pulleys are loose on the shaft and are adapted to be engaged alternately by a clutch R, sliding on a feather i bar t, extending upwardly through the tramper of the shaft. When the pulley P, is connected with the driving shaft. the plunger is moved upwardly, while the pulley "P is adapted to move the plunger downwardly. A rod r, is connected with the clutch, and with a bell crank lever 'r, the arm 7*, of which is connected with a rod r carrying stops or collars r W. The rod W, is secured to the plunger and is adapted to move vertically therewith. The arrangement is such that when the plunger has reached the limit of its upward or its downward movement, the collars acting upon the bell crank lever automatically throw the clutch out of engagement withthe pulleys. These devices are not intended to reverse the action of the press, as this is done by the operator by means ofa handle S, secured to a vertical rod 8, engaging with the rod 1". By this handle the clutch may be thrown into engagement with either the pulley P or P, to cause the plunger to rise or fall.

The plunger is provided with catch fingers n, which are adapted to engage with hooks n pivoted to the under side of the follower L. Four such fingers andhooks maybe conveniently employed, but a greater or less number may be made to do the work. When the plunger is moved upwardly, and comes into contact with the follower, the catches M,

are automatically moved outwardly on their of course, carries the follower with it, but

when it moves downwardly, were it not for some such looking devices, the follower might get caught in the baling box and become separated from the plunger, but by means of the locking devices or catches just described, the follower is made to descend co-incidentally with the plunger. As soon, however, as the plunger has reached the lower end of the bale box, the arms m of the catches nZabut against the inner ends of the brackets Z, as indicated in-Fig. 8, and are caused to assume the positions shown in that figure, and are separated from the catch fingers, so that the plunger may now be moved downwardly a short distance to the limit of its downward stroke, and separated from the follower.

In the tramper frame is a box T, arranged directly over a baling chamber, when in position for receiving a charge of cotton. The box T, is open at one side, and the cotton is fed in through this open side, and is delivered to the balin g chamber. A tramper head or platen T, moves vertically in the box T, and in the baling chamber arranged below The tramper is secured to a vertical rack frame, on one side engaging with flanged guide rollers 15, and on the other side. with a flanged cog wheel or pinion 75 The pinion Z is secured to a shaft i which carries a large driving gear wheel t having teethm, within its peripheral flange and teeth g, on its hub. The main driving shaft T of the tramper operating mechanism carries a piniont,

adapted to engage with either the teeth x or i 1 At its outer end, the shaft carries a flanged l belt pulley t.

A ball bearing connectsthe shaft to the tramper frame near the pulley t so'that the shaft may havea slight movement at this point to shift the pinion to engage with either the teeth w or y. When elevated, the tramper is held by a pawl t engaging with the teeth on the rack bar't, and a counterbalanced lever 19, tends to hold the pawl in engagement with this bar. As soon, however, as the pawl is disengaged from the rack bar, the tramper will fall through the tramper box and on to the cotton in the baling chamber.

To shift the pinion t so that it shall be disengaged from the teeth a or y, or made to engage with either the teeth a: or y,I employa lever T secured to an eccentric t through which the shaft T extends. This eccentric is mounted in a housing i secured to the traniper frame, and provided with adjusting devices 25 As the lever T is elevated, or depressed, the shaft is suitably shifted. When depressed, the pinion is made to engage with the teeth 00, on the periphery of the wheel 25, and the tramper is moved downwardly at a comparatively slow speed,

but with great power. When the lever is elevated, the pinion is made to engage with the teeth y on the hub of the wheel 15, and the tramper is elevated rapidly.

In order to automatically disengage the pinion t from the teeth y, when the tramper has reached the limit of its upward movement, I employ a stop on the rack bar 25,

which engages an arm on the inner end of the lever T. This stop causes the lever to lnove the eccentric in such a manner as to separate the pinion from the teeth 1 but does notmove it far enough to cause it to engage with the teeth on the periphery of the wheel; the tramper will thus be stopped and will neither move up nor down, and when thus disengaged, the pawl :5 engages the rack bar and holds the tramper elevated.

When sufficient cotton has been supplied to the baling chamber, the lever t", is operated to disengage the pawl t from the rack bar, and the tramper falls. If the lever t be released, itwill cause the pawl t to engage the teeth of the rack bar, anda furtherdownward movement be prevented, but in order that the pawl may be disengaged from the rack bar as soon as the pinion t is made to engage with the teeth cc, of the wheel 25', to further depress the tramper, I employ a chain t, connecting the lever 25", with the lever T and thus the pawl t cannot interfere with the operation of the machine, and there will be no danger of the pawls stripping the teeth from the rack bar, impeding the descent of the tramper, or in any way hindering the proper operation of the mechanism.

tical pivot 24, mounted on the platform D.:

When the sections are closed together, as indicated on the right-handside of Fig. 3, they constitute the upper portion of the baling chamber, but when open, as shown .on the left-hand side of Fig.3, there is a free space to allow of the compressed bale being. tied in the usual way, and moved off. laterally over the platform D, and the gin floor.

The end pieces 2 are hinged at u, to castings on the ends of the front and rear pieces 1, and rollers 3 are employed to separate the sections of the box, so that they maybe readily opened and closed. Theserollersmaybe run on tracks 4, as indicated. At each end of the front piece 1, is hinged a handleV, adapted to move abouta vertical pivot. Each of these handles may be composed of a bent rod 11, secured at its ends to end pieces or castings v, and these castings carry the hinges of the handles. l l

Tie rods W, hinged at w to the back piece 1, are adapted to extend over the ends of the front piece, and to enter notches '0 in the end pieces or castings o. When the handles are closedor lie flat against the front piece, as shown at the right-hand side of Fig. 1, the tierods are held inside the pivots of thehandles, and the sections of the box are firmly held together, and locked, and no strain inside the box can unlock thesections, but when the handles are moved outwardly, away from the front piece, as shown at the left-hand side of Fig. 3, the notches v are moved. past or outside of the handles, and the strain inside the box causes the tie rods to separate from the notches, and the sections swing open, as indicated, and the bale may be removed. By then moving the box sections together, causing the tie bars to engage witlithe notches Q2 and moving the handles inwardly, so that they shall assume the position shown in Fig. 9, or at the right-hand side of Fig. 3, the sides will be securely locked together again.

The operation of the press has been indicated in the foregoing description, but, briefly stated,the operation is as follows: When the mechanism is in the position shown in Fig. 1, the lint cotton is fed into the box T, and into the baling chamber over asection of bagging on the follower L, until a snflicient quantity has accumulated. Then the lever this depressed to disengage the pawl 25 from the rack bar. The tramper then falls as far as the cotton will allow it. Then the lever T is depressed, and power is applied in the manner hereinbefore explained, tofurther depress the tramper until the cotton is compressed sufficiently. The lever T is then raised and the gearingshifted to cause the tramper to be raised to the position indicated in Fig. 1. The stop then acts on the lever T to cause the disengagement of the pinion 25 from the rack, and

with the tramped cotton is then moved into position over the plunger N, and this is caused to rise and compress the tramped cotton into a bale. While the plunger is operating, cotton may be tramped in the baling chamber on the opposite side of the center post, as is usual in this class of presses. As the plun-r ger moves upwardly, it engages the follower L, and the catches 'n, 12. engage each other and securely lock the follower to the plunger. When the follower and plunger havereached the limit of their upward movement, the collarr", moves the bell crank lever and causes the clutch R, to be disengaged from the drivingpulley. Then the sections of the baling chamber above the gin floor are unlocked and swung open and the bale removed. By means of the handle S, the clutch is made to engage with the pulley P and the follower and plun-1 ger are moved downwardly. While they are descending, a sheet of cloth. or bagging is placed overthe follower, and this constitutes the bottom section of the packingin the balev next to be formed. When the plunger has reached the bottom of the baling box, it is automatically separated from the follower, as hereinbeforedescribed, and after having moveda short distance farther, the collar 0", engages the bell crank lever, and causes it to operate the clutch R, to disengage it from the "pulley P and thus the follower is stoppedr These operationsaresuccessively repeated: to form. successively the desired number of bales.
