HVIPROVEM ENT IN COTTON-GINS.
0 all whom it mfbg/ concer/1..'
Be ithnown that I, BENJAMIN D. GULLETT, of Aberdeen, in the county of Monroe and State of Mississippi, have invented certain Improvements in Cotton-Gills; and I do hereby declare that the following is a full, clear, and exact description of the principle or character which distinguishes them from all other things before known, and of the usual manner of making, modifying, and using the same, referencebeing had to the accompanying drawings, of which- Figure l represents a plan View of the gin; Fig. 2, a vertical section through` all the part-s; Fig. 3, aperspective of the brush-cylinder B, showing the end brushes, 7.,'.
My invention consists in certain improvements in cotton-gins, described and speeiiied as follows: A represents the common ginning cylinder, and B the usual stripping- A brush. Below this brush I place another brush, D, of equal size, which I call the carding-brush,7 and which by suitable gearing is caused to revolve about one-fourth as fast as the brush B. In front of these brushes I place a cylinder, E, which bears upon its periphery a series of comb-plates or brushes, a., which are made of steel saw-plate, as follows: The plates project beyond the periphery of the cylinder about three-fourths of an inch. The teeth are cut about five-eighths of an inch long, and number six to the inch. The combplates may be made of other material than steel; but I prefer the steel plate. The operation of the four cylinders thus arranged is as follows: The arrows indicate in Fig. 2 the direction in which each cylinder is to be revolved. The ginning and stripping are performed by cylinders A and B, as usual. The cotton is carded by brush B upon the brush D, and is stripped from this brush by t.the comb-brush cylinder E, and by it delivered into the flue-spaced below. The comb-brush cylinder also strips the gin-brush of adhering cotton, and it revolves at the same speed with this brush; but, being of greater diameter, its periphery moves at a greater velocity than the periphery of the gin-brush. Thus the comb-brushes operate as strippers and carders to the bristle-brushes, and by their combined operation the cotton is most effectually cleaned, and delivered entirely free from metes and knotty or matted portions. The diameters of the cylinders are as follows: cylinder E, fourteen inches; cylinder B, eight inches, and cylinder D seven inches, or about these proportions.
At the ends of the stripping and carding brushes are brushes K, having their bristles set in the direction of the aXis of the cylinder, and operating to clear away the cotton which ordinarily accumulates at these points, and which often takes-lire there from friction. Where the radial bristles of the brush terminate in ordinary cylinders, an eddy current of air is formed, which helps to accumulate the cotton there.
For the purpose of preventing the waste of cotton at the ends of the comb-cylinder, caused by the feeble draft of air at these points, I fix concave guards L, which prevent the cotton from falling with the inotesy by deilecting it toward the middle of the cylinder, where the draft of air is stronger than at the ends.
For the purpose of preventing the waste of cotton at the point F, and the consequent choking of the gin-cylinder by cotton carried round with it, I have arranged a blast-board, F, in such manner that whatever cotton tends to escape at this point is taken up and carried round by cylinder D.
That I claim as my invention is- 1. rlhe combination of the comb-brush E, the gin-brush B, and the gin A, in the manner set forth, the brush B being arranged between the comb-brush and the gin-brush, in the manner and for the purposes set forth.
2. The lower carding-brush, D, arranged and operating as set forth, in combination with the gin-brush and comb-brush, as set forth.
3. The blast-board F, in combination with the gin A, the gin-brush B, and the cardingbrush D, in the manner herein set forth.
4E. The end brushes, K K, constructed and operating as set forth.
5. The curved guards L, arranged and operating as set forth, in combination with the lower carding-brush, D, and stripper E, as set forth.
B. D. G'ULLETT.
