COTTON-GIN.
SPECIFICATION forming part of Letters Patent No. 389,091, dated March 30, 1886.
Application filed June 17. 1955. Serial No. 168,961. (No model.)
new and useful Improvi m ntsin (oiton-Gins.
of which the following is a full, clear, and ex act description.
My invention relates toa new and improved cotton-gin; and the object of my invention is to remove cotton fiber from the seed without breaking it or bending it sufficiently to injure it, leaving the fibers straight and parallel, and of nearly or quite full length, as grown on the seed.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure l is a vertical sectional elevation of my new cotton-gin on line 31y of Fig. 2. Fig. 2 is a broken sectional plan view of the same, taken on line a: x of Fig. 1. Fig. 3 is a detail view of the grating. Fig. 4 shows in detail a part of a cylinder with one of the teeth and a part of the grating. Fig. 5 is a sectional elevation of the central fan with its shaft and peripheral rods without brush f; and Fig. 6 is a detailed perspective view of a portion of the barrel L, showing the fingers i.
The frame 0 O and the legs N support the machine. The legs N support a frame, M, which supports an annular plate, P, the vertical shaft S, and the circular track (,1. These support the other parts of the machine.
The plate P supports the upright staves Ir, to which the gratings K are attached,and upon which the upper circular annular plate, P, rests. The plate P also supports a number of cylinders, G, turning on pivots I). The cylinders G terminate at their tops in shafts d, working in the bearings m, secured to the plate P, and these shafts carry cogwheels U,that mesh into a wheel, T, on the central upper short shaft, S, forming a continuation of shaft S. These wheels may be replaced by pulleys. The shaft S bears one or more helical flanges, H, (the latter, in the present instance, being of a single curvature,) which acts as a fan, and which also carries at the outer edge the brushes f.
The upper short shaft, S, fits into a socket at the top of shaft S, works in the bearing 0 in the spider-frame It, and carries the said wheel T, and also the pulley p,which receives the power.
The annular track 0 bears the conical barrel or hopper L. This barrel revolves about the central shaft, S, upon the wheels w, that run on the track a, the barrel being actuated by a cog-wheel, \V, geared into the toothed rim X, the wheel being revolved by the wheel U, (on one of the gear-wheels U,) through the wheel V on same shaft 0 as wheel \V.
The cylinders G may be of thin sheet-iron riveted to the heads a and 61. These cylinders are perforated at intervals with the holes 9. Into these holes are set the teeth 15. The points of these teeth work very close to the grating K on one side and the helical fan H and brushf on the other.
The grating K is of thin steel plates, and concaved in shape between the staves k and concentric with the cylinders G. The size of the bars of the grating K and the width of the slits, their distance apart, and their slope may vary.
The teeth f are of polished steel and finelypointed and the points tapered,and the points revolve close to the grating K, within one twentieth or one-thirtieth of an inch. Their size may vary from that in Fig. 4; but the shape shown in Fig. 4 I consider the best.
The fan H may be simply of sheet-tin secured to the shaft S. It revolves with the shaft S, and acts as a brush and fan for removing the lint from the hooks t. The circumference of fan H moves very near the hooks or teeth 15 on the cylinders G, and the brush f revolves with the fan. The brush f is attached to the edge of the fan H, and maybe of the ordinary kind,with thebristles sloping back from the direction of the motion, or it may be, as indicated in the drawings, of fine wire sloping back and set in a light band of rubber secured to the fan H. The small rods f, set in the edge of the fan H, answer the same purpose as the brush f, and may be used in connection with it or without it.
The helical fan creates a draft downward and inward to the shaft S at the same time, and draws the lint away from the teeth 15 and the brush f. The fan delivers the lint into a hemispherical basin, 1, from which it is taken being long and flexible and of such shape as to force the cotton down and against the grating at the same time. All these rods stir and turn the cotton. The cleaned seed drop out of a narrow annular space, 13, at the bottom of the barrel- The fibers being pressed into the slits of the grating K are caught by the teeth tand taken off from the seed.
The machine may be run at a much lower r te of speed than the saw-gin, and this fact, together with the shape of the teeth, obviates the tearing and wedging of the fiber.
The slits in the grating are too narrow to allow the seed to pass.
The barrel is kept in place by the two rollers 1*,placed at about one hundred and twenty degrees from the wheel WV on radial arms l.
The wheels adjoining the feed-box are protected from the cotton by a light shield, Q.
The tbppf the barrel, except in front of the feed-box, is protected by a light metal shield, S resting on the plate P, and the toothed cylinders G are protected or separated from each other by the curved division pieces or fenders G, arranged vertically between the said cylinders, as shown clearly in Fig. 2.
Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is.
1. In a cotton-gin, a circumferential feeding barrel or casing combined with several gratings, and several toothed cylinders arranged to run adjacent to the gratings, and a central fan for removing the lint from the teeth of the cylinders, substantially as described.
2. The revolving conical barrel L, to which the cotton to be ginned is fed, in combination with the gratings K, cylinders G, fan H, and brush f, the cylinders being provided with teeth t, substantially as and for the purposes set forth.
3. The barrel L, to which the cotton to be ginnedis fed, made conical and provided upon its inner surfaces with agitating-arms, in combination with the curved gratings K, toothed cylinders G, and central fan, H, substantially as and for the purposes set forth.
4. The conical feed barrel L, a circular track, 0, the vertical curved gratings K, vertical toothed cylinders G, and vertical central fan, H, all arranged as described, in combina tion with means, substantially as described, for revolving the feed-barrel, toothed cylinders,and fan, as and for the purposes set forth.
