COTTON-GINNING- MACHINERY.

To all whom it may concern:

Be it known that I, RALPH E. Wilson, a citizen of the United States, residing at Dallas, county of Dallas, and State of Texas, have invented certain new and useful Improvements in Cotton-Ginning Machinery; and I do hereby declare the following to be a full, clear, and exact description of the same.

The present invention relates to machinery for ginning cotton and is of such character that it may be embodied in ginning machines being manufactured or, in many types of ginning machines now in use, it may be combined therewith or embodied therein without changing the present relation of the working parts or altering the form and construction of the gin framing or casing.

The primary object of the present invention is to provide a means whereby the cotton will be more effectually fed to the saws to insure the operation of the saws at their full capacity when cotton is present to be operated upon and, further, to improve the quality of the cotton by preventing breakage of the fibers and by removing the fiber from the seed more effectually.

A further object of the invention is to provide a means whereby the cotton may be more effectually and rapidly separated from the hulls, leaf-trash, dust, dirt, gravel, etc., and whereby the necessity for stopping the feeding of cotton to the gin in order to ef fect the discharge of hulls, leaf-trash, etc., is avoided.

The invention is particularly applicable for use or embodiment in what are known as huller gins, although it may be used to advantage in any of the ordinary types of gin now in common use, such as the usual plain gin, or in delinting machines, commonly known as linters, etc., etc., and while l I do not wish to be restricted to any particular type of gin, I have adopted a huller gin as the type best adapted for illustrating the application of the invention.

The invention consists primarily in a cotton handling device or means located within the cotton chamber or breast of the gin but in front of the saws and ribs and adapted to impart to the cotton within the breast a movement transverse to the plane of the saws as well as a movement toward the saws, the movement transverse of the plane in which the saws rotate being such that the Specification of Letters Patent.

body of cotton presented to the saws is caused to sweep back and forth across the face of a plurality of such saws and at the same time be fed in toward the saws or in a direction contrary to the direction in which the cotton not engaged by the saw teeth would be thrown by the action of the saws alone. WVhile the invention may take the form of any one of a number of different de vices adapted to directly engage the cotton, it embodies in all instances a rotary carrier extending parallel with the axis of the saw cylinder and having upon it a multiplicity of diagonally arranged cotton engaging members which will force the cotton alternately back and forth in front of the ginning saws in a direction parallel with the axis of the rotary carrier and saw cylinder. The necessary extent of such movement is variable within wide limits, although practically it should have a range equal to not less than the distance between several of the saws and the cotton engaging members on the rotary carrier should be so located or spaced with relation to each other that each and every portion of the cotton being presented to the saws will partake of this reciprocatory or back and forth movement in front of or across the edges of the saws themselves, whereby the formation of channels or grooves in which the saws may run without engaging cotton in the breast is effectually prevented.

Referring to the accompanying drawingsFigure l is a perspective view of a gin of that type commonly known as a double rib huller gin, the outer or hulling breast having been removed and lowered to the floor in order to disclose the saw cylinder and the outer portion of the casing of the breast having been removed in order to disclose the spiked roller and the means whereby the cotton is presented to the saws in accordance with the present invention. Fig. 2 is a detail elevation of a shaft or carrier having cotton engaging and handling devices thereon of the preferred type. Fig. 3 is a sectional view through the gin breast and saw cylinder of the type of gin illustrated in Fig. 1. Fig. 4 is a similar view of a type of gin commonly known as a single rib huller gin to show the application of the invention to gins of this type. Figs. 5 and 6 are detail front and end elevations of a modified form of cotton feeding and han receives the cotton from any suitable the hulls, leaf-trash and other foreign matter is discharged. The cotton is carried into the inner chamber and thence through between the inner ribs to the brush or other means whereby it is removed from the saws.

In the particular type of gin illustrated in Figs. 1 and 3 outer gin ribs E separate the two chambers G and D while in the type of gin illustrated in Fig. 4 the gin ribs B are formed at B of such shape as to effect the separation of the chambers and in both instances the spiked roller F is located at the lower end of the outer chamber in the usual position.

All the parts so far described are of usual construction and form no part of the present invention save in so far as they may enter into the novel combination necessary in producing the advantageous results due to the employment of the invention, as will be now pointed out.

In accordance with the present invention, a rotary carrier G which may be in the form of a shaft or its equivalent is extended parallel with the saw shaft but in front of the saw cylinder, being preferably mounted or supported in this position by bearings g in the end frames of the gin breast. This rotary carrier or shaft G is provided with a multiplicity of diagonally arranged cotton engaging members which may be of various forms. As shown in Figs. 1, 2, 3, and 4 they are in the form of diagonally arranged oval shape disks H which, when viewed in front elevation, as in Fig. 2, are seen to occupy parallel planes diagonal with relation to the axis of the carrier and when viewed in end elevation, as shown in Figs. 3 and 4, appear to be substantially circular. This circular appearance corresponds to their path of travel in rotating about the axis of the carrier. The peripheries of the cotton engaging members do not pass in between the saws but are adapted to pass in proximity to the edges of the saws and intersect the planes of the saws. If desired, they may be set at such an angle that their peripheries will pass successively in proximity to a number of proximate saws, the object being to force the cotton to travel back and forth longitudinally of the saw cylinder and by the rotation of the cotton engaging members be also forced in against the edges of the saws in position for the saw teeth to engage thercwith, whereby the fiber will be carried away and the saws will operate at their full capacity whenever any cotton is present.

In the type of gin illustrated, the cotton handling device is located immediately above the spiked roller and operates to give a number of advantageous results in addition to its function of feeding the cotton to the saws, thus, it supports the weight of the mass of the cotton in the gin breast, leaving the spiked roller free to perform its intended functions of discharging the hulls, trash, and foreign matter. It also assists in shaking foreign matter out of the cotton and assists in preventing the discharge of any of the lint which might tend to follow the spiked roller without being engaged by the saw and, finally, it forces any cotton thrown away from the saws by their action, to be immediately returned to the saws where it is caught and carried off.

The device forms with the spiked roller a gradually contracting passageway which forces all the cotton into engagement with the saws.

Various forms of cotton engaging and handling members will suggest themselves and I have illustrated herein four of such forms, although I do not wish to be restricted to the particular forms illustrated or to any particular form save where particularly specified in the claims.

In Figs. 5 and 6 the shaft which in this instance is shown as a solid shaft G is provided with a series of pins H arranged in diagonal planes and the distance between the succeeding series of pins is such that cotton engaged and moved in one direction by one series will be engaged and moved in the opposite direction by the adjacent series being thus given a back and forth movement longitudinally of the axis of the shaft. In Figs. 7 and 8 the shaft or carrier G is shown in the form of a hollow shaft or pipe and provided with a series of diagonally arranged cut flights or disks H while in Figs. 9 and 10 a carrier G is shown provided with a series of angular pins H set at such an inclination with relation to each other that the pins on one side of the shaft will tend to move the cotton in one direction and the pins on the other side of the shaft will tend to move the cotton in the opposite direction longitudinally of the shaft.

In all the arrangements it is preferred that the cotton engaging members should be so arranged that the cotton being presented to the saws throughout the whole length of the shaft or carrier and saw cylinder will be moved simultaneously in one direction or the other and at the same time rotary motion is imparted to the carrier and cotton engaging members as well as to the cotton senses which is engaged thereby, the rotary movement of the carrier and cotton engaging members being preferably imparted through a pulley I (Fig. l) on the end of the shaft which may be driven by a belt K or other suit-able connections, whereby a sutficient speed of rotation may be imparted.

The direction of rotation should be in the opposite direction to the direction of rotation of the saw cylinder whereby the proximate edges of the cotton feeding and handling device and saw cylinder move in the same direction.

Having thus described my invent-ion, what I claim as new and desire to secure by Letters Patent of the United States, is
