IM'PROVEMENTIN COTTON-GINS.
Specification forming partlo f Letters Patent No. 222,366, dated December 9, 1879; application filed i June 12, 1879.
To all whom it may concemr [Be it known that I, HENREY N. REID, of Augusta, in the county of Richmond and Stateof Georgia, have invented" certain new and useful Improvements in Cotton-Grins; and
I hereby declare that the following is a full, clean-and exact description of the same, reference being had to the accompanying drawings, making a part .of this specification, in whicht Figure 1 represents, in perspective and with a portion of the side open, a cotton-gin having my improvements. Fig. 2 represents a vertical section of the same. Fig. 3 represents,
in top view, a series of stationary brushes detached from the gin. Fig. 4 represents a perspective view of the same.
My invention relates to cotton-gins in whidh the cotton-lint, after being cut from the seed by the gin-saws, is subjected to the action of 1 a revolving stripping-brush,jin conjunction with a stationary brush, to clean it andimprove its appearance. A
Heretofore various means have been used having that purpose in view, one of the oldest being to employ, in connection with a revolvin g stripping-brush, a stationary solid concave brush, slotted vertically for the passage of the saws, each slot being also lined on both sides with brushes. Others have used a stationary concave bed provided i simply with 3 whipping-bars, or with Whipping-bars in connection with brushes, and still retaining a solid concave. Although the cotton passed through gins constructed as above mentioned may be improved in appearance, nearly all the sand, dust, and other impurities that were previously therein, still remain, and the stationary solid brush, or its equivalent, soon becomes clogged and of little use.
The object of my invention is to open the tufts of cotton that have been collected and formed by the teeth of the saws, andremoved therefrom by the revolving stripping-brush, and to turn them inside out bymeans of series of stationary brushes extending across the" gin, and united by a skeleton-frame or bars, leaving open slots between each brush, and toprovide a still-air dust-receiving box placed ,under saidbrushes and slots,itoreceivethe dust and impurities immediately first of the rows of stationary brushes, where turned inside out, and the dust, sand, andother open slots 6, and into the still-air dust-box. The operation is repeated or completedin passupon their escape from the tufts, when the latter are turned inside out by the frictional contact of the revolving brush against the series of stationary open-slotted brushes.
My invention consists in combining, with the frame of a cotton-gin, its hopper,saws, and revolving stripping-brush, a still-air dust-box, located under the gin-saws, and provided with a top opening in front ofa .ver tical plane passing through the axisof the revolving stripping-brush, anda s eries'of transverse brushes separated by openings leading into said dust-box.
In the drawings, A represents the main frame-Work of the gin; B, the hopper; G,tl1 e gin-saws, and E the revolving stripping-brush. These parts are constructed and arranged in any Well-known manner. Under and at a short distance from the gin-saws is placed a dust-receiving box, D, having its topopen d.: To this box is attached, by means of a skeleton-frame or bars, b, a series of rows of upright brushes, 0, extending across the' machine, directly over. the opening d of the box I 1).. These brushes are attached to the barsb at such a distance apart as to leave openings or open slots 0, nearly equal in area to the surface of the brushes, I The bars b, uniting the brushes, are provided'with straps b and N, by which they are .se-
cured to the dust-box, or to transverse pieces forming the frame of the machine. The upper straps, N, are united to the bars by means of a hinged joint, b and each strap is slotted to receive a screw, f, so that the position of the series of brushes 1), in their relation to the. strippingbrush, may be adjusted to bring them in near contact or touching. A 7
By this construction the cotton cut from the seed, and carried out of the hopper in the form of tufts by the saws, is removed from the saw-teeth by the revolving strippingbrush, and brought vertically downuponthe the tufts are partly arrested. The central portion of each tuft, being the thickest, is retained proportionally longer. Said tuftsv become impurities released, and free to fall through the ing each of the succeeding brushes and open slots. These brushes and slots, being placed under the forward portion of the strippingbrush, or in front of a vertical plane passing through the axle thereof, in the eddy caused by the air-currents of the revolving saws and stripping-brush, or in and on both sides of a vertical plane tangent to both, do not interfere with the free delivery of the cleaned and straightened cotton through the passage a to the cotton-chamber.
I am aware that transverse permanent brushes, resting on a grating having openings leading out of the machine, have been used in connection with a rotary brush having vanes to produce and direct a current of air; but any advantage gained by this construction seems to have been overbalanced by the loss of cotton fibers forced out by said current of air carrying also the motes and impurities.
Having now fully described my invention, I claim- 1. In a cotton-gin, the combination of a hopper, B, saws O, and revolving strippingbrush E with a still-air dust-box having a slatted opening, and located in and on both sides of a vertical plane tangent to both the saws and stripping-brush, in the eddy caused by the meeting of the centrifugal air-current from said saws and from the stripping-brush, substantially as and for the purpose described.
2. In a cotton-gin, the combination of a hopper, B, saws G, revolving stripping-brush E, still-air dust-box D, located under the ginsaws, and provided with an opening, 01, in front of a vertical plane passing through the axis of the revolving stripping-brush, with the series of transverse brushes a, separated by openings 6 over the sti1l-air dust-box, substantially as and for the purpose described.
3. In combination with the saws of a cotton-gin, a still-air dust-box located vertically under said saws, and provided upon its open top with parallel brushes, which are separated by parallel openings leading into said dustbox, substantially as and for the purpose set forth.
