Serial No. 485,715.

To all whom it may concern:

Be it known that I, EMMETT LEE PETER- soN, a citizen of the United States, residing at vVillacoochee, in the county of Cofiee and State of Georgia, have invented certain new and useful Improvements in Cotton-Grins; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use thesame, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in apparatus especially adapted for ginning sea island cotton and comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described and then specifically defined .in the appended claims.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a gin made in accordance with my invention. Fig. 2 is a View in elevation from the opposite side of the machine. Fig. 3 is an end view, and

-Fig. 4 is a vertical cross sectional view.

Reference now being had to the details of the drawings by characters, A designates the frame of the apparatus which, in the present instance, is shown as inclosed with suitable surrounding wall, and journaled in suitable bearings within said frame are the two shafts B and C, the bearings of which have vertical adjustment, to the former of which is keyed a pulley D and to the latter a pulley D. E designates a counter shaft mounted in boxes T which are horizontally adjustable by means of the set screws T, as shown clearly in Fig. 1 of the drawings. The counter shaft has a driving pulley E fixed thereto and E designates a pulley which is fixed to the shaft E, and E designates an idler upon the latter. A suitable belt, designated by letter F, passes about the circumference of the wheel D and bears frictionally against the circumference of the wheel D and also about the pulley E, said wheel D serving to hold the belt taut and forming means for causing the two shafts B and C to rotate in opposite directions from each other. Fixed to the shaft B is a gin roller B having a suitable covering B shown in elevation in Fig. 3 of the drawings as being made up of strips, preferably of leather and rubber, interposed between the rubber strips of which are grooves B C designates a rock shaft which is mounted in the adjustable boxings H carried in suitable guideways in said frame, said boxings being held by means of the boltsGr and the screws G in adjusted positions. Fixed to said rock shaft is a cross beam H which has angled ends H apertured to receive the bolt I.

J designate stripper blades extending preferably the length of the cylinders and adjacent thereto. By reason of the boxmgs H being adjustable, it will be observed that the shaft Gr may be raised and lowered which will also allow the stripper blades to be adjustable.

Mounted upon the cross-pieces K, formmg a part of the frame of the apparatus, are the blades L which extend the length of the cylinders and held to said cross-pieces by means of bolts K. Said blades L may also be raised and lowered and held in adjusted positions, suitable set screws L being mounted in said cross-pieces and adapted to l1m1t the adjustment of the blades.

Fixed to the shaft G is an arm M, the lower end of which is pivoted at M to the arm M which is fixed to the crank shaft E.

Positioned over the frame in which the apparatus described is mounted is a hopper N in which cotton is placed and which is adapted to be fed forward to the gin. Mounted in suitable bearings in the walls of said hopper are the winged feeding Wheels N and N the former of which has a spindle N to which is fixed a ratchet wheel N The winged feeding wheel N is loosely journaled within the hopper and is moved by friction. A shaft 0 is ournaled in the opposite walls of the hopper and has a pinion Wheel 0 fixed thereto which is in mesh with a gear wheel 0 journaled upon the shaft 0*. A pitman Q, is pivotally connected to the wheel 0 at one end and its other end to a rocking bar P which is pivotally mounted upon a pin P carried by the hopper. A feeding drum 0 is mounted upon and rotates with the shaft 0 and has a series of teeth 0 thereon adapted to draw the cotton downward to the tapering exit opening in the bottom of the hopper. Said bar P has an angled weighted pawl P pivotally mounted thereon, the end of the pawl being adapted to engage the teeth of the ratchet wheel N and l? is a second pawl pivoted at P upon the lever P and is also adapted to engage the teeth of the ratchet wheel N By this construction, it will be noted that, as the bar P is rocked, a continuous intermittent movement will be imparted to the ratchet wheel N Immediately below the hopper is a tilting table R pivotally mounted at R upon the extensions R secured to the hopper, and R designates a rod adjustably connected at its upper end to the lever P and its lower end adjustably connected to the bar R which is fastened to the extension R thus causing said table to alternately tilt in one direction or the other as the bar P is tilted.

Mounted intermediate the two gin rollers are the inclined boards S adapted to direct a said crank shaft.

cotton to one roller or the other as it is guided to one roller or the other by the table R tilting. Mounted to have a horizontal movement below said inclined boards and resting upon the fingers S is a plunger S which is adapted to force the cotton against one roller or the other alternately as said plunger reciprocates. A rod S is connected at one end to said plunger and its other end to a crank shaft S journaled in the opposite walls of the casing, and a pulley S is pivoted to the end of said crank shaft S and has belted connection S with a pulley S fixed to the shaft C, whereby motion may be imparted to At the ends of the casing are the inclined walls W terminating each a slight distance below the gin rollers and Y designate dofl'ers which have arms Y fastened at their lower ends to said inclined walls while the transverse strip Y of the doflfers is positioned adjacent to each of the rollers, as shown clearly in Fig. 3 of the drawings, and extends substantially the length of the roller. Said strippers Y, it will be noted, are arranged so as to have a vertical adjustment by means of the bolts X which pass through the slots X.

In operation, power is applied to the shaft E driving the pulley E about which the belt F passes, said belt also passing about the wheel D and bearing with sufficient frictional force against the circumference of the pulley D to cause the latter to revolve in a direction opposite to the rotary movement of the wheel D. This motion will cause each ofthe gin rollers to rotate in opposite directions away from each other. The rock shaft G is operated by the connections between the same and the crank shaft as shown and thereby causing the stripper blades to move upward against the gin rollers. The cotton which is placed in the hopper is fed downward by the winged wheels, thence drawn by the pins upon the drum 0 down to the lower end of the hopper where it falls upon the tilting table R and the reciprocatseed from the cotton will be separated from the fiber, said seeds falling down through the fingers S, the fiber being removed from the cylinders by means of the doffers which are positioned adjustably adjacent to the rollers and against which the latter turn. The seeds as they separate from the fiber fall through the fingers, while the fiber free from the seeds falls down upon the inclined end walls of the casing, as will be readily understood.

Owing to the adjusting features of my gin, it will be noted that the various parts of the apparatus may be easily and quickly adapted for operating on cotton of various kinds.

hat I claim to be new is V 1. A cotton gin comprising a frame, vertically and laterally adjustable gin rollers and adjustable rock and crank shafts mount ed therein, an arm fixed to said rockshaft, a pitinan pivotally connected at one end to said arm and its other end to said crank shaft, a cross beam secured at right angles to the rock shaft and having upwardly turned apertured ends, rods fastened to the rock shaft and projecting through said apertured ends, stripper blades mounted on the ends of said rods and coacting with the rollers, nuts holding said blades against the outer edges of the upturned ends of the cross beam, stationary, adjustable stripper blades mounted adjacent to the gin rollers, and means for feeding cotton to the rollers.

2. A cotton gin comprising a frame, vertically and laterally adjustable gin rollers and a rock shaft mounted therein, a cross beam secured to said shaft and provided with upturned angled ends which have reg istering apertures therein, rods passing through the rock shaft and said apertures in j v a M"!
