I COTTON GIN. No. 324,457. Patented Aug. 18, 1885.
FIG.1.
F'IGA UNITED STATES PATENT OFFICE.
JOSEPH CARVER, OF BRIDGEWATER, MASSACHUSETTS.
COTTON-GIN.
SPECIFICATION forming part of Letters Patent No. 324,457, dated August 18, 1885.
Application filed May 16, 1885.
To all whom it may concern:
Be it known that I, JOSEPH E. CARVER, a citizen of the United States, residing at Bridgewater, in the county of Plymouth and State of Massachusetts, have invented a new and useful Improvement in Cotton-Grins, of which the. following is a specification.
My invention relates to an improvement in cotton-gins, with especial reference to the form of gin covered by Patent No. 20,120, granted to Wilson and Payne, April 27, 1858. This latter machine was designed for ginning cotton picked with the bulls, and was not intended or adapted to gin cotton which has been cleanly picked, for the reason that the saws are too Widely separated, so that the roll cannot be properly turned, and more or less cotton is wasted by being dropped between the saws and the toothed cylinder which carries the cotton to the saws; and, again, the channel or passage for theseed is too narrow. The seed must be very clean in order to pass through, and when the channel is clogged the process of ginning is much impeded. In the above-named patent each rib is provided with a projection or knuckle at or near its central portion, thus necessitating the rib to be wider than is proper for common cotton.
The object of my invention is to obviate the objections found to exist in the aforesaid machine, and to provide a means for effectively ginning cotton that has beencleanly pickedthat is, without the admixture of hulls, &c., or other extraneous substance.
The invention consists in constructing the rib with a flange on one side and made flush with the rib, a portion of the flange being provided with a projecting piece cut away so as to provide a single channel or passage for the free escape of the seed. This single passage is sufficiently wide to admit of the ribs being materially reduced in width, thereby allowing the saws to be brought nearer together.
Referring to the accompanying drawings, Figure 1 is a vertical section of a cotton-gin to which myinven tion is applied. Figs. 2 and 3 are enlarged views of the rib, each showing an =opposite side. Fig. 4 is a front view of a portion of the ribs and intervening saws.
The machine is constructed mainly like (No model.)
that shown and described in the Wilson and Payne patent.
A A represent the frame. B is the saw cylinder, to which aresecured the saws C. G
represents the hopper-frame. H is a partition in the hopper G. F is the toothed cylinder for carrying the cotton to the saws. These parts, being well known, need no further description.
D D represent a series of ribs secured at the ends, respectively, to the upper and lower parts of the hopper-frame, and between which ribs the saws revolve. On one side of each rib D is a flange, E, which is made flush with the rib at that side, and is provided with a piece, (I, projecting partially over the main portion of the rib at or near its center, and cut away at a point, e, to the flange E, as shown. By this means an opening or chan nel is provided for the passage of the seed, thusallowing of the free escape of the same, with little liability to clog, and at the same time admitting of the ribs being reduced to a suitable width for ginning ordinary cotton and still discharge the seeds freely.
In the ordinary saw-gin the cotton, which frequently contains stones or pieces of iron, I
is liable to prove injurious to the saws. In my improved construction the stones and pieces of iron are thrown back and not taken upon the tops of the saws, thus preventing injury to the same; and, further, the cotton being fed to the under side of the saws by the cylinder, much of the sand and dirt is also dropped at this point; but no cotton will be dropped, as the saws are placed at a proper distance apart from each other.
What I claim as my invention is- A cotton gin rib formed with a flange, E, at one side, the projecting piece (1, and the cut-away 6, whereby a single channel or offset is provided for the free escape of the seed, and the width of the rib lessened, as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnessc's. 1
