Description

invted Bietet 'JOHN W. WEBB, OF CTTON VALLEY, ALABAMA.
Letters Patent No. 90,210, dated May 18, 1869.
IMPRovnMEN'r IN coTToN-GINS.
wwe-
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern Be it known that I, JOHN W. WEBB, of Cotton Valley, Macon county, in the State of Alabama, have invented'certain new and useful Improvements in Cotton- Gins; and I hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, forming part of this specification.
The nature or essence of myinvention consists in arranging, under and behind the brush-cylinder, an inclined perforated moat-board or screen of woven wire, with meshes so small that the cotton will over the screen, while the dirt, sand, and other substances pass through the screen and are separated from the cotton; and in vibrating or agitating the perforated moatboard or screen, by means of a rotating cam-toothed wheel and shoe, to give the screen a jogging motion and shake the dirt through Vthe screen; also, in arranging some movable vibrating ends in the feed box, pressed towards each other by springs, so as to yield when the roll of cotton is large and to press it together, and prcvent it from breaking when it is small.
In the accompanying drawings I have shown as much of a cotton-gin as is requisite to show the application of my improvements.
Figure l is a front elevation of cotton-gin.
Figure 2 is a plan or top view.
Figure 3 is a section on'the line z z of iig. 2.*
In these drawings, A A are the sills in which the posts B B are fastened, which posts are connected by the. girders C O and D D, and by the top bars E'E, making a strong frame, to which the other parts are fastened or connected.
The top case or cover consists of the ends F lJ and top board G, to which the feed-box is hinged, which feed-box consists ofthe ends H H and front l, with top piece J, by' which it is hinged to the top board G, as shown iny iig. 2, so that it may be turned np when required.
Near the back edges ofthe ends H, l hinge the inside` movable ends K K, so as to vibrate or swing towards or from each other, and arrange the springs L behind them,"to press them toward the centre, as shown in iig. l, where the front is broken away, to show the end K and spring L, and in fig. 2, the plate M is alsov broken away to show the end and spring.
The object and purpose of these vibrating ends is to yield when the roll of cotton being ginned is full, and let the roll expand, and as the roll of cotton decreases, the springs press the vibrating ends in, and press the roll of cotton together, to prevent its breaking so soon as it otherwise would do.
N is the brush-cylinder which takes the cotton from the saw-teeth, and throws or blows it out of the rear ofthe machine into a lint-room.
Under the brush N, I arrange the inclined perforated the pulley S, to turn the shaft and cam-toothed wheel.
T, which acts on the shoe U, fastened to the under. side of the moat-board or screen-frame, and lifts it and lets it fall alternately to shake any matter through the perforations that are small enough to pass through; and under the rear part of this screen P, I make a box or receptacle, V, to receive the dirt, sand, &c., with a door, W, in the bottom, which may be opened to re move whatever may collect therein.
What I claim as my invention and improvements in cotton-gins, is
In combination with a sa\vcylinder and brush' of a cotton-gin, a woven-wire moat-board, arranged and agitated substantially as described.
Also,vthe movable vibrating ends in the breast or feed-box, pressedtowards each other by ,springs or their equivalents, substantially as described, for the purpose set forth.
