COTTON-GIN.

SEEGFIGATON forming' part of Letters Patent No. 668,470, dated February 19, 1901.

Application tiled April 18, 1900. Serial No. 13,325. (No modela .To all whom t ntctg/ concern.-

Be it known that I, WILLIAM HENRY WENT- WORTH, a citizen of the United States, and a residentof San Antonio,in the county of Bexar and State of Texas, have invented a new and Improved Cotton-Giu, of which the following is a full, clear, and exact description.

One purpose of the invention is to so construct a cotton-gin that the rollers, feed devices, and blades will be vertically disposed and arranged in groups, which arrangement by the multiplication of groups admits of a single gin-stand being economically erected which will equal the capacity of a battery of gins now in general use.

Another purpose of'the invention is to simplify the construction of cotton-gine and provide a speedy and effective separation of the seed from the fiber without injury to the latter and a thorough separation of the treated fiber from the seed.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the 'Iigures Figure 1 is a perspective view of the improved gin. Fig. 2 is a horizontal section taken practically on the line 2 2 of Fig. 3. Fig. 3 is a vertical section taken substantially on the line 3 3 of Fig. 4, and Fig. 4 is a `horizontal section taken practically on the line 4 4 of Fig. 3. A

The gin is preferably of cylindrical shape, and the body comprises a circular base A, a circular head B, and a cylindrical body C, of less diameter than the head and the base. The body C is substantially independent of the base; but the head B is attached to the base A through the medium of suitable rods 11 or their equivalents. The base A is provided with legs 10, whereby the gin may be secured to the floor or other support.

The body C is provided with a bottom 12, in which a circular opening 13 is made, as shown in Figs. 3 and 4, and a corresponding opening 14 is made in the base A, as illustratcd in Figs. 2 and 3. Toothed guide-rollers 15 are mounted in the upper surface of the base, between the periphery thereof and the central opening 14, and a master-wheel D is mounted to travel on these toothed guiderollers 15, the master-wheel having teeth 1G upon its under surface, and the said masterwlieel is further provided with teeth 17, formed in its inner edge, and teeth 18, produced upon its outer edge, as is best shown in Fig. 2.

In order that the master-wheel may revolve and not be subjected to undue friction by reason of the weightof the body O, plain friction-rollers 19 are fitted in the bottom portion of said body, as illustrated in Fig. 3, which plain friction-rollers engage with the upper surface of the master-wheel D, which surface is plain. The master-wheel is turned by engagement with a gear 20, the `gear meshing with the bottom teeth of the master-wheel, and this gear is mounted on a shaft 21, provided with a suitable pulley 22, adapted for connection with any source of power.

The body C is divided into a series of compartments E and chambers F, alternately arranged, the compartments being separated from the chambers by vertical partitions 23, which extend from the outer surface of the body to the edge of the opening 13 in the bottom of the body, and an opposing vertical partition 24, which extends from the outer surface of the body to a point about midway between the said surface and the edge of the said opening 13. The partitions 23 and 24 are curved or bowed outward or in opposite directions except at their outer edges, which portions 25 ot' the said partitions are straight. The space thus formed in each compartment E is adapted to receive a feed board or plate 26. These feed boards or plates are attached by means of pivots 27 to the under surface of the head B, as shown in Fig. 3, while arms 28 vare pivctally attached to the outer faces of the said feed boards or plates near their lower ends, which arms extend out through suitable openings in the body-casing and are pivot-ally connected with crank arms 29,

formed in shafts 30, journaled at their upper4 ends in suitable brackets 31, carried by the body-casing, and the lower ends of the shafts 30 are suitablyjournaled in the base A. Each shaft 30 has a pinion 32 secured thereto, and these pinions mesh with the exterior teeth on the master-wheel D. Therefore as the masterwheel revolves the feed plates or boards 26 are laterally reciprocated,swinging upon their pivots. In order that cotton shall not stick in the bottom portion of the section of the compartment E in which the feed-board is located, the bottom c of this portion of each compartment E is inclined from the body-easing downward and inward, as shown in Fig. 3. A vertical roller 33 is mounted to turn in the wider portion of each compartment E, which compartments are adapted to receive the seed-cotton, and these rollers are journaled in any suitable manner in the head and in the base of the gin, the trnnnions or shafts of the rollers passing loosely through the floor 12 of the body C. Each roller 33 is preferably provided with a covering 34 of hide, having the hair on the outside and cut off short, or the rollers may be covered with any other material adapted to attract and take hold of the seed-cotton. As the rollers revolve they carry the seed-cotton to two blades 36 and 37, located at the spaces in the compartments Eformed by the shorter partitions 24, as is illustrated in Fig. 4. The blade 36 is a stationary blade and is attached to an upright support 35, which extends from the bottom of the body C to the head B, quite close to the edge of the central opening 13 in the said bottom, and these blades 36 are adapted to engage with the peripheral surfaces of the rollers 33, as is also shown in Fig. 4. The blades 37 are movable to and from the stationary blades 36, being guided in ways produced in blocks 38, located upon the inner face of the head B and the bottom l2 of the body C. Each movable blade 37is preferably provided with two arms 39, and these arms extend through suitable openings in the body-casing and are pivotally connected with crank-arms 41, formed in shafts 40, said shafts being journaled in the head B and the base A. Each shaft 40 at its lower end has an attached pinion 42, which meshes with the exteriorI teeth of the master-wheel D. Thus as the master-wheel is revolved the blades 37 are moved to and from the Xed blades 36.

The seed-cotton is fed into the compartments E through openings 43 made in the head B, and as the seed-cotton is thus fed to the compartments E it falls between the feed boards or'plates 26 and the rollers 33. After it has been separated from the seed by the action of the blades 36 and 37 the fiber is delivered to the central openings or wells 13 and 14, while the seeds fall to the ground through openings 44, made in the bottom 12 of the body, and corresponding openings 45, produced in the baseA; but it will be understood that the cotton may be conducted to any desired point by suitable conveyers passing beneath the wells 14, and conveyers likewise may be provided to receive the cotton-seed. Each of the rollers 33 is provided below the bottom of the body C with an attached gear 46, as shown in Figs. 2 and 3, and these gears mesh with the inner teeth 17 of the master-wheel D, and by this means the rollers are made to revolve simultaneously with the movement of the 1 movable blades 37 and the feed boards or plates 26.

In operation the seed-cotton is forced by the feed-boards to the rollers and the rollers conduct the seed-cotton to the space between the fixed and movable blades, and by reason of'the action of the movable blades in connection with the fixed blades the cotton-seeds are forced from the fiber and by reason of their weight drop down to the exit-openings 44, while the iiber passes beneath the stationary blade to the opening 14. (See Fig. 2.) The chambers F are very useful, as they enable the blades to be adjusted or any cotton that may clog to be started on its way, and to that end each chamber F is provided with a door f, made in the body-casing.

When a gin is constructed as above set forth, the risk of fire is greatly lessened and the mutilation of the operator is made almost impossible. The gin can be used for cleaning or burring wool or mohair and all raw material of such class, it being understood that when the machine is so used the rollers are changed, as the grease, dto., from the wool would injure the cotton ber. By subjecting the fiber to the action of the stationary blades while the Iiber is gripped by the rollers the ber is not only separated from the seed, but compressed, leaving the fibers parallel.

Having thus described my invention, I claimas new and desire to secure by Letters Patent- 1.
