RIB POR UTTON GINS.
Patented Deo. 18, M383.
UNITED rArns A'rnNr trice..
WILLIAM S. REEDER, OF ST. LOUIS, MISSOURI.
me FOR COTTON-ems.
SIEECIFICATION forming part of Letters Patent No. 290,471, dated December 1S, 1883. Application filed August 27, 1883. (No model.)
To all whom, it may concern:
Be it known that I, WILLIAM S. Rnnnnn, of the city of St. Louis, in the State of Missouri, have invented an Improved Bib for Cotton-Gins, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
In the drawings, Figure 1 is a vertical section of a portion of a cotton-gin, showing a saw and my improved rib in elevation. Fig. 2 is a front view of a number of my ribs. Fig. 3 is a side View of the upper portion oi' a rib and saw on a larger scale. Figs. 4., 5, and 6 are sections taken on the lines44., 5 5, and 6 6, respectively, Fig. 3.
A represents the hopper,and B the saws of an ordinary cottongin. C are my improved ribs, which are provided with means for attachinent to the gin-body. Each rib has a rearward extension or projection, D, near the upper portion or end, as shown. In this rib and in line with the acting teeth of the saw I form a long opening or slot, E, transverse of the rib, having an entrance, F, through the front of the rib. The saw-teeth are arranged to work beside the openings or slots in the ribs. The body of the projection D is prefen ably made thin, and has iianges G and H around it, G being the lower ange and H the upper flange. The thin body ofthe projection may extend below the lower flange. The entrance F to the opening or slot has a flat roof and a dat iloor,while the roof of the main portion of said opening is curved, first upward and then downward, and its door descends with an abrupt curve from' the entrance F, gradually rises to the middle portion of the iioor, next inclines downward, and then npward to join the roof, the bottom of the opening being formed in the lower flange and located at the base of the teeth, except at the part immediately in rear of the entrance, which is depressed, as stated.
The operation of a cottongin having my i improved ribs is as follows: The seeds and very coarse matter are separated from the cotton-as the latter is pulled through the entranees F of the ribs by the saws, and the cot ton passing into the main portions of the I openings or slots, the fibers lapping over one, two, three, or more of the saws, as the case may be, is brought against the doors of the main portions of the openings, the motes and dust separated therefrom, and the fibers which overlap two or more of the saws are pulled by the saws on either side from the other saws between the ribs from the iioors. The rear ends of the openings or slots form better bearings than usual for the cotton to be drawn 1 over, and are less liable to break or cut the fibers. The rise in the depressed portions of the floors of the openings or slots slightly raises or lifts the cotton in the teeth of the saws as it is being separated, thereby preventing its gumming or binding, and loosening it ,so that the motes and dust are more thoroughly removed.
I claim as my inventionl. A rib for cotton-gins, formed with a transverse slot open at its front end and closed at its rear end.
2. A rib for cottongins,having a slot transverse thereof, an entrance to the slot at front of the rib, and a depression in the door of the slot at rear of the entrance.
3. A rib for cotton-gills, formed in one piece, having a rearward projection, iianges extending around the projection, a slot in the projection, and an entrance to the slot through the front ofthe rib.
