y t UnireN THEO. I. JAMES, OF SHIRT TAIL BEND, MISSISSIPPIr iVIPROVENENT l`N SAW-GINS FOR GINNIN'G COTTON.

Specification forming part of' Letters Patent ho. "2,60, dated May 7, 18112.

T0 all whom, t may concern:

Beit known that I, Trrnononiox I. JAMES, of Shirt Tail Bend, in the county of Washington and State of Mississippi, have invented a new and useful Improvement in the Construction of CottonGins, which is described as follows, reference being had to the annexed drawings of the same, making part of this specification.

Figure l is a vertical section of the front grate-saws, false grate and mote-board, fanbrush, and ofthe additio'nal brushes and guide or conducting plate, the frame being omitted, as this can be varied in its forni, according to the character of the gin, and as the inside of the frame may, with very slight modifications, be adapted to the position of the above-mentioned parts. Fig. 2 is a perspective view of the conducting-plate and the ribs or triangular noses thereon for conducting the trash separated from the cotton by the revolving brush between the saws and down between the cylinder of the saws and the stationary or hanging brushes to the floor. Fig. 3 is alongitudinal section of a revolving cylindrical brush, composed of a'series of circula-r blocks or brushes slipped on the shaft,with round pieces of paper, leather, or thin blocks or washers put between them to adapt the cylindrical brush to the various kinds ofgins already in use; Fig. 4, a section of one of the aforesaid circular blocks of brushes, showing the apertures therein to receivethebristles or splints composing the brush arranged in tangential lines to the circumference of the shaft, and the circular grooves to admit the cord that is entwined in the bristles, and which secures the same in the block, the bristles being arranged on lines tangent to a smaller curve than that of the block, for the purpose of preventing the teeth of the saws striking against the ends of the wires, bristles, duc., and driving them endwise toward the cylinder and doubling or breaking them, or causing them to interfere with the motion of the saws, and causing said rotary brush or whipper to keep itself free from dirt, or clogging as the particles of broken, leaf, Src., leave the brush in the direction of the slope of the bristles or wires. Y

The frame of the gin-stand is made of suitable size, form, and strength for the purpose intended. The revolving saws A, a fan-brush B, front grate, C, false grate D, and m Ote-board E are made and arranged in the frame in the ranged above the saws and running counter to them, and a stationary hanging brush, G, arranged between the revolving brush F and false grate D and fan-brush B, and the lower ends extended between the sawsA ,for preven ing the dirt passing with the\cotton through the false grate D to the fan-brush B, the saws running through said hanging brush G, and also of an inclined conducting-plate, H, iluted or ribbed and arranged between the whipper F and brushes G, and extending nearly to the extremities of the teeth of the saws, for conducting the broken leaves and dirt, dto., separated from the cotton by said rotary brush F, between the saws, where it is met by the vertical stationary brush G, which prevents it from again uniting with the cleaned cotton, and is directed downward to the place of deposit for the trash and dirt. The additional revolving and improved brush is made in the following manner: When the gin-stand is of an entire new construction, it consists of a cylinder, F, perforated on the circumference to adinit the bristles, wire, splints, dto., composing the brushes, which are arranged in lines tangential to the circumference of the axle of the cylinder, or ot' a curve of less diameter than the cylinder, so that in running counter, 'or against the saws, the teeth of the latter will not tear out, double up, or break the bristles, wires, Src., but will merely bend them and allow the teeth to pass freely through them, while the bristles or wires beat and break the leaf and dirt` in the cotton and separate the same therefrom, conveying them around in the direction of the arrow in Fig. l and discharging them upon the inclined conducting-plate H, which conducts the trash between the saws and brushes Gand mote-board E toa place of deposit below the saws, while the saw-teeth carry the cotton under and past the conducting-plate H through the hanging brushes G and false grate D,(which scrape off the loosened particles of leaves and dirt,) and is met by the fan-brushes B,which take it from 'the saws and drive it through the flume to the place of deposit beyond the said fan-brush B. The before-described tangential arrangement of the bristles of the brushes also causes the brush to clean itself of the dirt which it separates from the cotton, as before described,and to create a current or draft between the saws and hanging brushes, which hanging brushes effectually prevent the draft from blowing the dirt through the false grate D among the cleaned cotton.

When lthe counter-revolving brush is to be made and adapted to the common gin-stands 4 in use, whose saws are of various diameters and distances apart, the brushes should be composed of the separate round blocks of brushes, like th ose representedv at Fig. 4, put on the shaft, with washers or thin blocks between them, to adapt them to said saws, in the manner represented in Fig. 3.

The hanging brushes G are made in thc following described manner: rllhe bristles or wires of which they are composed are secured in a horizontal rectangular block and project down therefrom, forming a continuous brush a little more than the length of thc saw-cylinder and of suitable width, which block is arranged transversely in the frame between the saws and false grate and parallel with the several` axles, the saws running through said brushes-being designed principally for prebent down in front of the brush G until nearly l touching the saws, which part may be fluted or provided with a row of nose-pieces for conducting the dirt more efectually to the spaces v ots or cones arranged in the frame, having pulleys around which are passed bands, in the usualmanner of gearing together such description of revolving parts, the power applied being of the ordinary kind; or the cylinders of the saws and whippers may be geared together by a band passed around them.

Cotton 'ginned in the above-described giustand will be almost entirely free from dust, dirt, and l-eaf or trash, and consequently eve-ry pound will be rendered more valuable than when ginned in the common gin heretofore used. n

lVhat I claim as my invention, and which l desire to secure by Letters Patent, is-

The employment of the additional brush F and the stationary brush G, in combination with the saws A of the saw-giu, in the manner described, and also the plate H, in combination with the brush and saws, as described, for the purposev of cleaning the cotton of dust and trash while undergoing the process of ginning, whether arranged in the precise manner before described or in any other mode substantially the same.
