Specification of Letters Patent.

Application filed October 22, 1900. Serial No. 33,852.

f0 (6 whom it may concern.

Be it known that I, GEORGE A. LOWRY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Cotton- Gin, of which the following is a specification.

This invention relates to cotton-gins.

The objectof the invention is to render more efficient, simple, and economical the construction of this class of apparatus.

The invention consists, substantially, in the principles of construction as detailed in the subjoined specification, as illustrated in the drawings, and more particularly pointed out in the claims.

Like reference-signs refer to similar parts in the several figures of the drawings, in which Figure 1 is a vertical sectional view of a form of machine embodying the principles of the invention. Fig. 2 is an enlarged detail, in vertical section, parts broken oif, of aform of conveying apparatus for the seed material.

Fig. 5 is a broken detail view, in top plan, ofthe construction shown in Fig. 4. Fig. 6 is a plan view of the construction shown in Fig. 1 with part of the covering over the conveyer broken away. Fig. '7 is an enlarged detail of a form of feed-hopper, partly in section, on the line 2 2, Fig. 6. Fig. 8 is a broken view, in vertical section, of a slightlymodified construction embodying the invention. Fig. 9 is a top plan view of another modified construction embodying the invention. Fig. 10 is a broken detail view in sec"- tion on the line l0 10, Fig. 9. Fig. 11 is a similar view on the line 11 11, Fig. 9."

In previous'patents granted to me, notably Patent No. 581,601, is described and claimed a press for compressing cotton and other materials in which are employed a compression chamber or holder and a slotted cap or head, the fiber to be subjected to compression being passed or drawn through the slots in the head and into the chamber or holder and built up in superposed layers of high density by causing a relative movement of the slotted head and the chamber or holder and offering resistance to the advancement of the compressed material. l have found that a press of this construction when modified in such manner as to prevent the seeds from being drawn between the moving mass of cotton and the cap-plate will remove the fibers from seedcotton and that by making certain additions for properly presenting the seed-cotton to the slotted head and removing the seeds after the fiber is stripped therefrom an exceedingly ellicient cotton-gin will also be produced.

In the accompanying drawings are shown various forms of mechanism adapted to carrying out the principles of my invention, and these will now be described; but I desire it to be understood that my invention is not to be limited to the particular construction or type of machine set forth.

Reference sign A designates a suitable frameworkin which is mounted an open-ended chamber or holder (1, and B is a cap or head plate for one end of such chamber or holder, said cap or head plate being provided with one or more slots or openings I 'therethrough and which are arranged to extend in a general radial direction. The chamber or holder 0 is designed to contain a mass P of material which exerts a pressure through the expansive force thereof against the inner surface of the cap or head plate. Relative movement may be imparted to this mass and the headplate in any suitable manner. In the particular form shown a pulley D is driven from a convenient source and through the engagement of a gear E, rotated thereby, with a rack F, secured to or carried by a flange projecting from or connected to the chamber or holder, said chamber or holder is rotated, the cap or head plate being held stationary. To reduce friction, the chamber or holder may be supported upon antifriction-rollers G, as shown. It is obvious that other forms of gearing and construction for securing relative movement of the chamber or holder and the cap or head plate might readily be substituted for that shown and above described, so far as the present invention is concerned and equally Well answer the purpose in view, or the chamber or holder may be held stationary while the head-plate is rotated, or they might both be rotated, but in different directions or at different speeds.

Reference-sign N designates a suitable feedhopper into which the material to be ginned is placed. A brace O may serve to steady (ygg and support this hopper. Within hopper N is arranged a conical deflector N, having the base thereof extending to a point adjacentto or beyond the outer end of the slots in the head-plate. By this arrangement the material to be ginned when placed in the hopper will be deflected toward the perimeter of the cap or head plate. In order to accomplish this result, bridges N in the form of doubleinclined sheds are provided and arranged to extend from the apex of the conical deflector toward the base thereof and are of increasing width to the point where they join the deflector at the lower edge of the latter.

It is obvious that, if desired, the feed-hopper may be omitted and other forms of devices employed for properly presenting the material to the slots in the head-plate. In Figs. 9, 10, and 11 I have shown the feedhopper omitted.

It will be understood that the mass of material in the chamber or holder exerts a pressure or expansive force against the inner surface of the head, and by reason of such pressure or expansive tendency such material will tend to bulge or expand upwardly into the slot, as most clearly indicated in Fig. 11. It will also be seen that the surface of this bulge or expanded portion cooperates with the lip of the slot in the head-plate to form a contracting throat between the surface of said lip and the mass of compressed material in the chamber or holder. Now by imparting a relative movement to the mass of material and the surface or abutment against which it exerts a pressure then the surface of such material, which bulges or expands into the slot by reason of the wave-like or rolling motion thereof during such relative movement, cooperates with the surface of the lip of the slot in the head-plate to exert a gripping action on the fibers of fresh material presented adjacent to the slot and the outer surface of the head-plate, thereby drawing such additional fiber into the chamber, and hence adding to the body of the mass of material contained therein, and by preventing or restraining the seeds of the seed-cotton from following the fiber or from being drawn into the chamher or holder with the fiber such fiber will be stripped from such seeds. The seeds may be prevented or restrained from following the fiber or from being drawn into the chamber or holder in many different ways. One form of means for accomplishing this result is the peculiar shape of the lip bounding one edge of the feed-slot. In the form shown the inclined or beveled under surface of such lip meets the inclined or beveled upper surface of such lip at a point below the medial line of such lip, and the resulting contracting throat formed by the cooperation of the surface of the lip of the slot in the head-plate and the surface of the compressed material which bulges or expands into the slot, as clearly indicated in Fig. 11,

excludes from passage through the slot any object of the size of a seed, while permitting the entangling of the fibers of the seed-cotton with such compressed material and the drawing into the chamber of such fibers as the compressed material moves. Of course it is understood that the seeds are oval and comparatively hard, and when stripped of the fibers or lint and rolling upon the compressed material, which latter is very dense, they are excluded by reason of lack of space from passing into the chamber. If the compressed material were not up to proper density or the shape of the slot at its edge adjacent to the contact of the seed was quite flaring, so as to provide a space for the entrance of the seed, the exclusion of such seed could not be as certainly effected; but with the construction shown in Figs. 10 and 11 and described and proper density of cotton there is no trouble on this score, as in practice such construction has achieved the resultdesired. Asimilar resultthat is, the exclusion of the seed-may be obtained by other means than that just described, one example of which is illustrated in Fig. 3 and consists in making the slot too narrow to permit a seed to pass therethrough.

In the construction shown as illustrative of operative embodiments of the invention the pressure employed to exclude the seeds is secured by the expansion of the compressed material. I do not desire, however, to limit or restrict my invention in this respect. I wish it to be understood that this is one mode of accomplishing the end desired and the preferable mode so far as my practical experience has demonstrated.

If desired and in order to properly present the seed-cotton or other material to the slot so that the fiber thereof may become entangled or engaged with the fiber of the mass of material which is exerting an expansive force or pressure against the inner surface of such head-plate or so as to be eflficiently gripped between the surface of that portion thereof which bulges or expands into the slot and the adjacent surface of the lip of the slot, a movement of the fresh material or seed-cotton along and lengthwise of the slot may be effected. Many specifically different constructions may be devised and adopted for effecting this movement or travel of the seed material. In Figs. 1, 2, 6, and 8 of the accompanying drawings, H designates one form of conveyer adapted for this purpose. In Figs. 4 and 5 an endlesschain conveyer H is shown. The conveyer H is in the form of a spiral plate or blade carried by a shaft which is journaled in a bearing I and carries at its outer end a pinion 1, arranged to mesh with a double annular rack B, which is also engaged by a pinion I", carried by a shaft 1', suitably journaled in the framework A and driven by a belt passing over pulleys l I from the main shaft. The double rack B may be supported in any suitable manner, as by means of rollers G upon a track carried by the main frame.

In the form of conveyer shown in Figs. 4: and 5 the endless chain H is provided with projections or teeth, and said chain is mounted above and in proximity to the slot and extends lengthwise thereof. This chain is carried over sprockets H one of which may be driven by a bevel-gear H engaging a pinion H upon the inner end of the shaft which carries the pinion I In Figs. 1, 2, 3, 4, 5, 6, and 8 I have shown means for feeding the seed material lengthwise of the slots in the head-plate.

In Figs. 9, 10, and 11 I have shown a construction in which positive feeding mechanism is omitted.

It will be understood that special feeding mechanism is in some cases desirable and is used as an auxiliary part of the invention; but it may not be necessary in all cases.

By the arrangement and operation above set forth a longitudinal central opening through the mass of material P is produced, and by progressively moving the seed and seed material along or lengthwise of the slots not only is the fiber efficiently and thoroughly stripped from the seeds, but the seeds are finally delivered into the central opening through the mass of material and may be delivered therefrom through a delivery opening or pipe L or otherwise. The progressive movement of the material along or lengthwise of the slot should be so regulated and timed that when the length of the slot has been traversed the fiber will be entirely and thoroughly stripped from the seeds.

The desired pressure of the mass of material against the inner surface of the cap or head plate in order to enable such material to exert an expansive force against such surface may be secured in any desirable or suitable manner-as, for instance. by means of a plunger M of a hydraulic jack upon which is carried a base or support K, which engages the mass of material P, or, if desired, by making the chamber or holder slightly conical or tapered.

Instead of having the seeds drop through the central opening through the mass of material they may be removed in other ways as, for instance, by means of a suction-blast. One form of means for accomplishing this result is shown in Fig. 8 and which comprises a blower S and pipe R, through which the seeds may be drawn. In Figs. 9, 10, and 11 is shown an arrangement of suction-blast wherein is provided an exhaust or suction flue R over each slot in the head-plate, each flue extending lengthwise and being slotted the length of the slot in such manner that the seed-cotton may approach the opening or slot in the head-plate and the seeds after they have been stripped of their lint or fiber may pass or be drawn into the fine and be discharged or delivered, by means of the blower or fan S, to any suitable point. All the fines R are arranged to communicate with and to deliver into a common flue or passage R with which the fan or blower S communicates.

It is obvious that one or more slots may be employed in the head-plate, and the greater the number of slots the greater rapidity of action is secured. It is also obvious that the mass of material drawn into the chamber or holder or which is added to the moving mass, as above explained and set forth, may at the same time be built up and compressed into a column of high densityby the action described and from which column portions of the desired length to form commercial bales may be detached.

From the foregoing description it will be observed that I employ relatively moving surfaces, one of such surfaces being slotted and the seed material being presented to such slot, so as to permit the fibers thereof to be engaged or gripped between such relatively movable surfaces and stripped or drawn from the seeds, the adhesion of the lint to the seeds being overcome in the manner above described, whereby the seeds may be removed independently. This is the broad principle of my invention, and while I have disclosed such broad principle as applied to a type of machine wherein the fiber when stripped from the seeds is at the same time built up into a compressed mass such a type of machine is not essential in carrying out my invention, and the baling feature may be dispensed with, the generic idea being based on the utilization of relatively movable surfaces, between which the fiber is gripped or engaged, and at the same time to restrain the seeds, whereby the fiber is drawn or stripped from the seeds.

Many other modifications, variations, and changes in the details of construction and arrangement will readily suggest themselves to persons skilled in the art and still fall within the spirit and scope of my invention. I do not desire, therefore, to be limited or restricted to the exact details shown and described; but now, having set forth the object and nature of my invention and various constructions embodying the principles thereof and having set forth and described such constructions and the purpose, function, and mode of operation thereof,
