IMPROVEMENT iN icor'rowelws.

Specication forming part of LettersPatent N0. 4,175, dated March 3, 1874;,application lcd January 17, 1874.

To all whom it may concern:

Be it known that I, EDWARD BUCKLIN, J r., of Pawtucket, in the county of Providence and State of Rhode Island, have invented a new and valuable Improvement in Cotton-Gills 5 and l do hereby declare that the following is a full, clear, and exact description of thefconstruction and operation of the same, reference being had to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation of a longitudinal sectional view of my cottongin. Fig. 2 is a plan, and Fig. 3 a transverse sectional, view ot' the same. Figs. 4, 5, 6, and

7 are details of the saine.

This invention, 'has relation to machinery which is designed for separating seeds from cotton, my object being to perform this work without the use of saws, which, it is well known, injure the cotton bers more or less. llIy invention consists, mainly, in the employment, in a novel manner, of reciprocating combs and a holder, with feeding or taking-oft' rollers, whereby the seed-cotton will be tlrmly held over an opening through the-feed-table, while the combs remove the seed from it, one comb acting to press out the seed, while the other comb clears it of adhering cotton, as will be hereinafter more fully explained. The invention further consists in novel mechanism for actuating the separating-combs and the reciprocating holder.

The following is a description of my invention:

In the annexed drawings, A designates the frame of the machine, on which is an inclined table, a, that supports and holds in place a hopper, B, throughv which latter the cotton is fed to the separators. C C are two rollers properly journaled in the cheeks of frame A, and arranged horizontally, for feeding or drawing in the cotton and discharging it over a lixed apron, b. The upper roller C may be clothed with leather, or some other suitable material, and the lower roller C maybe serrated longitudinally, similar to the drawin grollers 7 of spinning-machines. The upper roller C is held in contact with the lower one,

C', by means of springs in the journal-boxes. D is the main driving-shaft, carrying on one end a spur-wheel, c, and, between the cheeks of frame A, an eccentric. Spur-wheel c engages with another spur-wheel, c', which is keyed on the shaft of roller C', on which shaft is also keyed a spur-wheel, cl, which gears with a spur-wheel, d', on a shaft, E. Shaft E carries an eccentric, c, which, by means of a yoke and connecting-rod, f, communicates a reciprocating motion to two arms, g g, which vibrate on a horizontal shaft, F. Arms g-g are connected by rods l1J h to a vertical]y-reciprocating head, Gr, to which a separating-comb, G, is secured, the teeth of which are on its lower edge and may be constructed in any suitable manner. The head G is constructed with vertical slots through it near its extremities, through which screws ifi'pass, which loosely attach the head to a pressure-plate, J, the ends of which are guided by vertical slots through side bear-V ing-:plates H. Beneath the table a, and in close relation to its bottom side, is a reciprocating comb, a, which is secured to a slide, N, that works forward and backward in guides on the bottom of the table a, and receives its movements from the eccentric i', through the medium of a yoke and connecting-rod, i".

If desirable, the two combs (SH-a may be adjustably secured to their respective plates.

In feeding the cotton, with seed and leaf in it,` between the rollers G G", it passes over a slot, s, through the table a, which slot is in close relation to the rollers and directly below the comb G. The first operation is the descent of the plate G, which presses the cotton which is between the said slot s and the rollers O C down iirmly on the table a, and holds it there. Thecomb G then descends through slot s and presses out the seed, and as the comb G ascends the comb n advances to it and clears .the cotton from its teeth. During these operations the cleaned cotton is being discharged over the apron b by the rollers O C. It will be observed that the teeth of the comb G do not tear or in any manner injure the fibers of the cotton, but simply pass down through and separate the seed from it while it is being held by the plate J.

The uished sliver is prevented from being Wound around the upper roller C by means of a vertically-rcciprocating beater, L, the arms of Which are fast on an oscillating` shaft, L. This shaft L' may be oscillated by means of a crank-arm, P, connecting-rod P', and a wrist pin, p, on the spur-Wheel.

That I claim as new, and desire to secure by Letters Patent, is-

l. Reciprocating` combs Gr n and a pressureplate or holder, J combined with takingbff rollers, substantially as described.

2. The pressure-plate or holder J loosely attached to a rertically-reciprocating head, Gr,

so that it will press the sliver 011 the table ct in front of the opening s, previous to the operation of the comb Gr on the cotton-seed, substantially as described.

3. The combination of the holder J and stripping-comb a with a Seedseparating comb, G', substantially as described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two Witnesses.
