SPECIFICATION forming part of Letters Patent No. 256,429, dated April 11,

Application lcd April 5, 1881. Renewed Marchi?, 1882. (No model.)

' thereof, reference being had to the accom panying drawings, and to the letters of reference marked thereon, which form part of this specilication.

This inventionrelates to a combined cotton gin and press.

The main objects of the improvement are to reduce to a minimum the delay and trouble incurred in erecting an outfit byrendering the` gin-house unnecessary, and to construct, with the exception of the steam-engine, an entire machine for ginning and pressing cotton in a cheap, compact, and portable form; also, to reduce the number of hands which are usually employed for ginning and pressing cotton, as will be apparent from the following specification. f

In the drawings, Figure lis a side elevation of my machine. Fig. 2 is a longitudinal central section taken on a vertical plane. Fig. 3 is a vertical section on the line w Fig. l. Fig. 4 represents the packer detached. Fig. 5 illustrates the tie-holder, and Fig. 6 shows a portion of the rack-frame and devices for raising or lowering the pinion arranged in said frame.

A indicates the main frame of the machine. This will be supported by wheels, so that it can be readily moved from place to place, as may be required. The means employed for driving the .saw-shaft consist of a belt-pulley, B, secured upon a shaft, b, and driven by a belt from the engine, a bevel-gear, b', secured upon the same shaft and gearing with a like bevel-gear, b2, upon a shaft, b3, and adrum, C, secured upon said shaft and connecting with a pulley, c,- upon the saw-shaft c by means of an endless belt, c2.

D indicates the rotary gin-brush,which strips the cotton from the gin-saws and blows it up through the inclined flue dto the condenser d', which is formed by means of the two rotary cylinders d2 cl3, between which thecotton is passed and condensed.

E refers to the lint-chamber, into which the cotton drops from the condenser through the opening eof a trap, which is closed by a door, e', during certain periods in the operation of the machine, as will be presently explained.

F refers to the packer, which consists of a series of vertical bars, f, arranged at equal distances apart, and aseries ofhorizontalslats, f', also arranged at equal distances apart, and secured toa thick iron plate, f2, which eX- tends across the bottom of the lint-chamber and constitutes the base of the packer. The bottom of thelintfchamber is formed with longitudinal slots e2 to admit of the connection of the packer with rack-frames G. The rack- V frame G employed in connection with my invention is provided with two lines of internal teeth, g g, and between the said lines of teeth is arranged a pinion, H, that is mounted upon a shaft arranged to be raised or lowered, so as to bring the pinion into gear with either the upper or the lower set of teeth. The mechanism i'or thus operating said shaft consists of a movable wedge, h, connected with a lever, 71.', that can be operated either to force the wedge under a bearing, h2, of the shaft,so as to raise the same, or to withdraw the wedge from under the bearing toadmit of the' descent of the shaft, in order to bring the pinion into gear with the lower set of teeth. Thus while the pinion, during vits rotation, engages one set of teeth, the rack-frame and packer will be carried in one direction, and when it is shifted to` engage the other set of teeth the rack-frame and packer will be moved in a reverse direction, whereby the packer can be moved back and forth at the will of the operator. v

The device for shiftingthe wedge consists of a crank-wheel, h3, connecting with the lever h by means of a connecting-rod, h4,`and the means for operating the pinion consist of a belt, I, passing around a` belt-wheel, I', upon the pinion-shaft anda belt wheel or drum, I2, upon a sleeve on the saw-shaft, said sleeve being arranged to be engaged with a clutch by means of a crank-handle, I3, so as to cause its rotation simultaneously with the saw-shaft, or to be disengaged therefrom, so as' to remain idle, and thus check the movement of the packer.

K represents the balefholder, consisting of vertical iron bars k, secured to a rail, 7e', and triangular-shaped plates L, secured to a thiclt iron top plate, L', that is connected with the rail or horizontal top bar of the bars k by means of eyebolts l. Ropes k2 extend up from the rail k' over pulleys k3, and are provided with weights ki, and ropes L' extend from the plate L over a pulley, M, and thence down to a crank-wheel, m. The triangular plates L are ofthe same thickness as the vertical iron bars k, and are made to it into grooves in the rear sides of said bars.

N indicates the bale-box, which is in front of the bale-holder. The follower which works in the bale-box is composed ot' two blocks, O 0f, the former of which is acted directly upon by the screw O2. The blocl; O is provided with pins passing through slots P in the side boards, 1), and it is adapted to hold the cotton within the balcbox by a yielding pressure by means of a rope, p', which connects .therewith and passes around a pulley, p2, and over a hook or staple, p3, and is provided at itsend with a weight, p4. This block is arranged to swing upon its pivots 1f when the doors 196 of the bale-box are open, so as to facilitate the placingl ofthe bagging thereon. Itis also provided with mortises p7 to receive the dowels p8 upon the block O.

Q, indicates the head-block, which is suspended by a rope,q, that is carried down from the top ot' the standards q' and connected with the shaft of a crank-w heel, q2. Heavy timbers R R are arranged, as shown in i'ull and dotted lilies, Fig. 2, to receive the pressure during the operation of baling.

S Indicates a drum mounted upon a shaft, s, which is coupled with or uncoupled from the shalt b by means of the side-acting frictiongearing s and a lever'. s2, which can be operated to force the shaft s toward the shaft I), and thus bring the friction-gearing together, or which can be swungr away from said shaft, whereby the rotation ot' shaft b will disconnect said gearing. The druln S imparts motion to the screw when the said shafts b and s are connected by means ot helting, for which purpose I provide upon the screw1 two nutblocks and collars. s3, and the. three pulleys s4, the center one being fast and the outer ones loose. In this connection I employ two belts, 011e ot' which will be crossed, whereby the screw can be driven back and forth by shitting the open or the crossed belt upon the fast pulley, as the case may be. S indicates braces lor holding thenut-bloclis. In Figs. land 2 l have shown the inclined slides S2 I'or the under doors ot' the bale-box N.

T indicates the tie-holder, having a series of vertical bars, t, formed with channels for holding the ties, the number ot' said bars or sheaths admitting of a dozen ties being held thereby, it' required. The tie-holder is raised so as to bring the ties around the sides and bottom of the bale within the bale-box by means of the crank-wheel t', having a pinion, t2, upon its shalt, and a pinion, t3, connecting with the crank-wheel by a connecting-rod, t, said pinions being arranged to engage with the vertical rack-bars t5. Ou the shaft of one of these pinions is a pawl, t, to prevent the descent ot' the rack-bars until the pawl has been released from the racltbar.

The letters U- V refer to steelyards and 1fting apparatus for lifting and weighing the bales. drops from the compressortlinto the lint-chamber so long as the packer F 1s back under the lower cylinder ot' the compressor, as shown iu Fig. 2.

In order to move the packer forward, so as to carry the cotton into the bale-box, the operator turns the crank-wheel h3, so as to bring the pinion within the sliding rack-trame into mesh with one ofthe sets of teeth in said frame, by means of which the rotation of the pinion will move the rack-frame and consequently the packer forward. The pinion is set in motion by turning the handle I3, so as to engage the pulley I2 with the saw-shaft by any suitable clutch mechanism, said pulley transmitting motion to the drum upon the pinionshatt by a belt, I. As the packer moves forward it strikes against and raises the door c', so as to close the opening at the top of the lint-chainber. This door is hung upon a rod secured in the sides ot' the lint-chamber, and it is provided with an arm, c3, carrying a weight, e4, which, after the packer has passed forward beyond the door, holds the samein a vertical position until, by reversing the above-described operation ot' the pinion and bringing the saine into engagement with the other set of teeth in the rack-frame by shifting the wedge, the packer returns and causes the door to drop by the action of a spring, e5, carried by the packer, against the weighted arm c3 of said trap or door. As the packer advances its vertical bars f pass between the triangular plates L and the vertical bars it ofthe bale-holder, said plates and bars being now connected by means ot the eyebolts l passing through the bar k into the plate L, to which the triangular plates are secured. During this forward movement of the packer the lint which is carried by the same is wedged under the plates L, so as to raise the bale-holder to a sulcieut height to admit oi' the passage of the lint under the same and into the bale-box N. The forward movement ofthe packer will be continued until it is aboutthreeiuchcsin advance ofthe bars lcofthe bale-holder, at which point it is stopped and the bale-holder allowed to drop to nearly its former position. Thepositionanddirectionot'rotation of the pinion H will now be changed by the' means hereinbefore described, so as to bring the packer back to the position shown in Fig. 2, whereby the trap-door e will be opened and the lint which has accumulated upon the guard e while the door has been closed will drop through opening e into the lint-chamber in front of the packer. The guard c6 here reA ferred to consists of a series of inclined fingers with spaces between them to admit of the pasln operating this machine the cotton IOO IIO

the weight p4, will be gradually pushed back as the bale-box is filled until it abutsagainst the block O, that is acted upon by the screw,

said block O' being arranged to swing upon its pivots when the doors of the bale-box are open 1o to facilitate the operation of putting the bagging upon it, and being further provided with a large groove, O2, in which the edges of the bagging are secured. -After the bale has been 4packed in the bale-box the part L L' of the holder is detached fiom the bar lo by withdrawing the eyebolts l, and it is then elevated by turning the crank-wheel m. Thehead-block Q is then let down by turning crank-wheel q2,

Y said head-block coming in front of the heavy timbers R, which aiford suitable resistance to the great pressure which it sustains when the follower' is advanced toI compress the bale. After the head-block isin position the remain` by the weight 704 and the follower advanced to press the bale by rotating the screw by means of the devices before described. After this operation the doors of the bale-box can be removed and the tie-holder, with the ties for the bale, run up to their place on the bale by operating the crank-wheel t. Thus in a space of about three minutes one man can inclose, tie, sew, lift out, and weigh the bale by means before described, and in about two minutes more have the box ready for another bale-' au amount of labor which has heretofore occupied about half an hour when performed by two men. The ties will all have an equal tension, and thus be less liable to break than when they are put on one at a timeand pounded instead of pressed onto the bale. In transporting this machine the screw can be run in and the tie-holder elevated, the lower portions of the rack-bars being turned up on their hinges t7 t7.
