COTTON-GIN.

Specification of Letters Patent.

Patented Aug. 14, 1906.

Application filed December 4, 1905. Serial No. 290,056.

' citizen of the United States of America, and

a resident of the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Cotton-Gins, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in cotton gins, and particularly to improvements in roller cotton-gins.

My invention consists, first, in a novel form of rotary stripping means; second, in a combined stripping and feeding member, and, third, in a novel form of double gin in which a single rotary stripping member opcrates in combination with two ginning-rollers and two bed-knives. In carrying out the third said feature of my invention I so provide that any material which is not completely ginned after presentation to one ginning-roller will be then presented to the other ginning-roller, and so on continuously from one to the other until the material is completely ginned,

My invention also consists in certain novel details of construction and combination of parts, as will hereinafter be more fully pointed out.

In order that my invention may be fully understood, I will now proceed to describe an embodiment thereof with reference to the accompanying drawings and will then point out the novel features in claims.

In the drawings, Figure 1 is a front view of a cotton gin embodying my invention with certain parts removed and broken away in order to show other parts at the rear thereof. Fig. 2 is an end view of the gin. Fig. 3 is a view in vertical transverse section through the ginning-rollers, stripping member, and correlated parts.

5 5 designate end frame members, which constitute supporting means for the working parts of the gin. Mounted in suitable bearings carried by the said frame are shafts 6 6, which carry ginning-rollers 7 7. The said ginning-rollers 7 may be any suitable form of rollers such as are ordinarily employed in roller cotton-gins, being conveniently covered with walrus-hide or other material to give them the required surface. These rollers are arranged to rotate in the same direction, being driven from a pulley 8 upon a drive-shaft 9 by means of a belt 10, which passes over the said pulley 8, over pulleys 11 upon the shafts 6, and around an idler ten sion-pulley 12. Stationary bed-knives 13 of the usual or any desired construction are arranged tangentially of the rollers 7 7 proximity to the peripheries thereof. The said knives are secured to and carried by breast-bearns 14 and are arranged to point in similar directions with respect to the direction of rotation of the rollers with which they cooperate, but being arranged inproximity to adjacent sides of the roller point in opposite direction with respect to each other.

Mounted between the rollers 7 7, with its axis in a plane with the axis of said rollers, is

a combined rotary stripping and feeding member 15. This member comprises a cylindrical shell 16, suitably journaled in bearings carried by the frames 5, stripping-fingers 17, and picker-fingers 18. The strippingiingers 17 which comprise each a cylindrical straight bar or peg, project radially from the periphery of the shell 16: and are of a length sufiicient to almost but not quite engage the peripheries of the rollers 7 7 and: the faces of the bed-knives 13. Thesestripping-fingers are arranged in a series of lines around the circumference of the shell 16, each line comprising a plurality of substantially equidistantly-spaced fingers along the length of the saidshell. The preferable arrangement of such stripping-fingers is astaggered relation longitudinally of each line or series with respect to the adjacent line or series, alternate lines or series being in the same transverse planes. The picker-fingers 18 are arranged in lines or series circumferentially intermediate the adjacent lines or series of strippingfingers, the said picker-fingers being shorter than the stripper-fingers and referably curved or bent into substantial y a hook form, as shown in the drawings. These hook like fingers are arranged to point in the direction of rotation of the member 15 and longir tudinally the said fingers are arranged to point between the stripping-fingers immediately in advance of them, being in the transverse vertical lanes of the stripping-fingers to the rear of them. The disposition and relative arrangement of the said fingers will be readily understood by inspection of Figs. 1 and 3 of the drawings.

The stripping inember 15 is rotated by a belt connection 19 with a. pulley 20 upon the shaft 9. The belt connection 19 is shown as a crossed one, so as to give the member 15 a surface direction of rotation in the same direction as the surface movements of the rollers 7 7. The relative direction of the roller and stripping members is shown by means of arrows in Fig. 3. ."Immediately beneath the stripping member 15 is a grid 21, preferably constructed in the form of a curve concentric with the said stripping member. This grid is arranged to permit clear passage of seeds therethrough, but to prevent the passage of cotton fibers.

Cotton to be ginned is fed into the space above the stripping member between the upper breast-beam 14 and a wall 22, arranged above the roller 7 opposite thereto. Such space forms, in effect, a hopper. With the parts rotating in the direction of the arrows, Fig. 3, the cotton to be operated upon is carried by the stripping device toward the righthand roller, the picker-fingers 18 operating substantially as feeding means. The fibers which adhere to the right-hand roller 7 are carried round thereby, the seeds being held back by the bed-knives 13, as will be well understood. The stripping-fingers 17 form a plurality of stripping devices which tend to nock the seeds down onto the seed-grid, separating them from the fibers. That portion of the cotton which is not properly ginned by the right-hand roller will be carried round by the combined feeding and stripping means to the left-hand roller, where it wi 1 be given another chance to be ginned at this point, the left-hand roller operating on such material as is carried past the righthand roller. This action thenis continuous, for the feeding action of the combined stripper and feeder will be such as to continuously carry the material from one roller to another until it is completely ginned. The seeds will drop down through the seed-grid, to be carried off in any suitable manner. The ginned cotton will fall away from the ginning-rollers or may be taken away therefrom in any desired manner, and any suitable means may be employed for this pur ose as is desired.

The peculiar form an construction of the central member is such that the strippingfingers and picker-fingers each perform their particular functions independently of but in proper relation to the functions of each other.

. The picker-fingers being considerably shorter than the stripping-fingers in no way interfere with the action of the stripping-fingers, nor do they act themselves in any way as stripping devices, While the stripper-fingers being substantially radial act but little in the capacity of feeding means, the hooked form of the picker fingers especially adapting them for this purpose. The arrangement of the hooked picker-fingers in staggered relation to the stripping-fingers in advance of them causes them to pick up such unginned cotton as is knocked off the bed-knives by the stripping-fingers, the stripping-fingers having a tendency to deflect the material directly into the paths of movement of the said picker-fingers.

What I claim is 1. In a cotton-gin, the combination with a ginning-roller and a bed-knife, of a combined stripping and feeding device comprising a rotary member having radial stripping-fingers and1'1 radial picker-fingers alternating therewit 2. In a cotton-gin, the combination with a ginning-roller and a bed-knife, of a combined stripping and feeding device comprisin a rotary member having radial strippinggers and radial picker-fingers alternating therewith, the stripping-fingers projecting outward farther than the picker-fingers, and the picker-lingers being substantially hook-like in form. I

3. A combined rotary stripping and feeding member for a roller cotton-gin comprising a support and a plurality of lines or series of alternate stripping and picker fingers arranged longitudinally and circumferentially of the same, the lines of picker fingers arranged in staggered relation with respect to the lines of stripping fingers immediately in advance thereof.

4. A combined rotary stripping and feeding member for a roller cotton-gin comprising a support and a plurality of lines or series of alternate stripping and picker fingers arranged longitudinally and circumferentially of the same, the lines of picker-fingers arranged in staggered relation with respect to v IIO same direction, and tangential bed-knives coacting with adjacent sides of the peripheries thereof, of a combined rotary stripping and feeding device arranged between the rollers for cooperation with both of them.

7. In a cotton-gin, the combination with two ginning-rollers arranged to rotate in the same direction, and tangential bed-knives coacting with adjacent sides of the peripheries thereof, of a combined rotary stripping and feeding device arranged between the rollers for cooperation with both of them, said device comprising lines or series of strippingfingers alternating with hook-like pickerfingers.

8. In a cotton-gin, the combination with two ginning-rollers arranged to rotate in the same direction, and tangential bed-knives coacting with adjacent sides of the peripheries thereof, of a combined rotary stripping and feeding device arranged between the rollers for cooperation with both of them, said device comprising lines or series of strippingfingers alternating with hook-like picker-fingers, the picker-fingers arranged in staggered relation with the stripping-fingers immediately in advance of them.

9. In a cotton-gin, the combination with two ginning-rollers and stationary bedknives cooperating with the peripheries thereof, of a combined rotary stripping and feeding means arranged between the rollers, for cooperation with both of them and with their respective bed-knives, said rotary stripping and feeding device including means for successively presenting the material backward and forward from one roller to the other for successive ginning operations.
