Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed November 4,1905. Serial No. 285,935.

T0 (LZZ whom it may concern:

Be it known that I, ELLIs B. ANDERSON, a citizen of the United States, residing at Demopolis, in the county of Marengo and State of Alabama, have invented new and useful Improvements in Combined Feeding, Cleaning, and Elevating Apparatus, of which the following is a specification.

This invention relates to a combined feeding, cleaning, and elevating apparatus.

The device can be used with advantage in many different connectionsfor example, in handling seed-cotton from wagons to gins. It may be employed, however, in a cottonniill for handling lint-cotton and in an oil mill for separating the meats from the hulls. of seed.

An apparatus involving my invention is simple in construction and effective in operation, it serving to rapidly and uniformly supply clean cotton to a gin.

In the drawings accompanying and forming a part of this specification, I illustrate a simple form of embodiment of the invention which, to enable those skilled in the art to practice said invention, I will set forth in. detail in the following description, while the novelty of said inventionwill be included in the claims succeeding said description.

In the drawings, Figure 1 is an elevation of a feeding and elevating apparatus including the invention. Fig. 2 is a side elevation of a feeder, and Fig. 3 is a vertical sectional elevation of the same. Fig. 4 is a perspective view of feeding and cleaning mechanism and certain adjunctive devices, hereinafter more fully described. Fig. 5 is a sectional clevation, with parts removed, of a feed device,

hereinafter more particularly described.

Like reference numerals indicate corresponding parts throughout the several views.

In Fig. 1 I have shown a combined feeding and elevating apparatus in full and a battery of gins in connection with said apparatus. The battery is three in number, each of the gins being denoted by 2. Over each gin is arranged a feeder, and I will denote each feeder in a general Way by 3. In Figs. 2 and 3 I have shown in detail one of the feeders.

A pneumatic elevating conduit is shown at 4, the lower end of said conduit being adapted to dip into a wagon-box to draw the cotton from said wagon-box upwardly and to supply it to a conduit 5, shown as horizontally disposed and constituting really a continuation or part of the elevator. The conduit 5 is supported upon the tops of the easings 6 of the several feeders, as indicated clearly in Figs. 1, 2, and 8, said tops having openings, as 7. Extending across the rear lower sides of the feed cr-casings 6 is a suctionconduit, as 8, communicating with the interiors of the several casings by means of openings, as 9, .in said casings. (See Figs. 2 and 3.) In practice a suction fan or blower, as 10, (see Fig. 1,) is connected with one end of the conduit 8 for drawing air therethrough through the feeder-casings 6, conduit 5, and elevating-conduit A, so that when the lower end of said conduit 1 is contiguous to asuppl y of cotton such cotton will be drawn into the conduit 4 upward thercthrough and along the conduit 5, from which it can drop through the openings into the casings 6 onto cleaningcylinders, as 11. When one feeder 3 receives its full supply of cotton, the next adjacent feeder is supplied with cotton, and so on. The suction is continuous, so as to maintain a constant supply of cotton. The cleaningcylinders 11 are located practically directly under the respective supply-openings 7, so that the cotton can fall directly from the conduit 5 to said cylinders. Each cylinder 11 consists of complemental end spiders 12, fastened in some suitable way to a shaft, as 13. The rims of the spiders are connected by narrow strips, as 1 1, surrounded by the circular reticulated portions 15, which extend from one spider to the other. The. spiders are located adjacent to the side Walls of the respective casings 6, by reason of which each reticulated cylindrical cleaner extends entirely across the interior of its casing. The several cleaners 11 are in the path of the aircurrents traveling from the respective openings 7 to the respective openings 9. It therefore follows that when the cotton falls onto the cleaners air-currents are drawn through the mass of cotton through the cleaners, openings 9, and into the exhaust or dust conduit 8. The cleaners 11 are rotated positively in the present case, by reason of which fresh portions of their peripheries are brought into the path of the falling cotton. Air-currents enter each cleaner 11 at or near the top thereof and leave the same at substantially diametrically opposite points, thereby removing any fiber from the surface of said cleaner or cylinder that may have caught on the same at the top or at the place where the cotton falls thereupon. As the surfaces of the cleanersare at all times kept gear 30 upon the main shaft 31.

thoroughly clean, it is evident that less power will be required to elevate cotton from a wagon than if the said surfaces were not clean.

A valve is shown at 16 in each casing 6, by closing which the feeder having the same is thrown out of action. The valves when shut close against inclined boards, as 17, in the respective casings in proximity to the openings 9. The valves 16 are mounted for swinging motion, and one of each of their pivots extends through its casing 6 and is provided with a crank, as 18, connected to a suitably mounted andguided bar 19. By the manipulation of the bars 19 valves may be opened or closed. On reference to Figs. 3 and 2, it will be seen that there is located in the casing 6 a flat valve 20, pivoted to one side of the opening. In both of said figures the valve 20 is shown as being open, the valve 20 at this time standing vertically and hanging downward. To close the opening 7, the valve 20 will be swung upward until it covers said opening. To a pivot of the valve 20 is fastened a crank-arm 21, to which is joined one end of a bar, as 22, suitably mounted and guided upon the casing 6. By moving this bar endwise the valve to which it is connected may be opened or closed to throw into action or out of actionthe feeder with which said valve is directly associated.

I will now describe in detail a convenient means for operating each cleaner 11, and in this connection reference may be had particularly to Figs. 2, 3, and 4. One end of the cleaning-shaft 13 extends beyond the casing 6 and rigidly carries a ratchet-wheel, as 23, with which two pawls, each denoted by 24, are cooperative, the pawls being pivoted to slides, each designated by 25. The slides are carried by and longitudinally adjustable on a rocker, as 26, fulcrum'ed upon one side of the casing 6. The slides are located at opposite sides of the center of motion of the rocker, and by adjusting them the stroke of the pawls can be regulated, by reason of which I can govern the speed of the cleaner 11. The slides will be maintained in their adjusted positions by means of set-screws, as 27, carried thereby and adapted to engage the rocker. I have shown as connected with the upper endof the rocker a rod 27, the opposite end of said rod being connected to the wrist-pin 28 upon the gear 29, driven by the When, therefore, the main shaft is in operation, the gear 30 will be operated, so as to through the intermediate mechanism oscillate the rocker 26 and cause through the pawl-and-ratchet mechanism hereinbefore described the positive motion of the cleaner 11.

Upon one end of the shaft 31 I have shown a driven member, such as a pulley 32, operated by a belt 33 from the ginning mechanism. The shaft 31 extends entirely across the casing 6 and rotatively carries a feeder, as that denoted in a general Way by 34. The feeder 34 rotates in contact with the cleaner 11 and also in contact with a concaved strip, as 35, fastened to the casing adjacent the said feeder at a point opposite the cleaner 11. Located above the concaved strip 35 is an inclined board 36, which prevents the accumulation of cotton on the top of said concaved strip. This inclined board directs cotton onto the feeder. The concaved strip 35, as will be understood, has an air-tight fit against the feeder. The feeder has a longitudinally-corrugated core, as 37, to the cor rugations of which are fastened strips, as 38, constituting blades, of some suitable flexible material. The strips or blades 38 extend between the heads 39 of the feeder, the core, heads, and strips being connected together in any desirable way. The feeder, as will be understood, is carried upon the main shaft 31 and has a continuous movement, the spaces between its blades presenting pockets in which cotton can fall. When the pockets are inverted, the cotton in them will gravitate into a spout, as 40, extending from the casing 6 and to the ginning mechanism. Said feeder 34 is shown as rotative in eontiguity to the cleaning-cylinder 1 1, by virtue of which said feed device or feeder 34 aids in cleaning the cotton, in that it carries the cotton in scrubbing contact with the cleaning-cylinder.

At a point above the board'l7 and upon that wall of the casing to which said board is attached I fasten an inclined board, as 41, which prevents cotton passing between the cleaner 11 and the'said wall.

In connection with each cleaner 11 I pro vide means for loosening the cotton up while on said feeder, whereby air can pass freely through the cotton and remove effectually and thoroughly all moisture and dirt from the cotton. In addition to this, said means turns the cotton up in a continuous roll and in a direction opposite to that in which said cleaner is turning and at the same time distributes the cotton evenly the Whole length of the cooperating feeder 34. I will now set forth the means illustrated for securing these novel functions.

IVithin the casing 6 is a hollow rotative drum 45, having journals or gudgeons, as 46, at its opposite ends supported by bearings in or upon the side walls of the casing. Suported by the gudgeons 46 is a non-rotative shaft, as 47. The drum'45 is rotated by sprocket-gearing denoted in a general Way by 48 and connected with the shaft 31. The offset portion of the shaft 47 is provided with a multiplicity of radial arms, as 49, adapted to work through perforations in the body of the drum 45, said arms being loosely connected with said offset portion. That part of the shaft 47 or the offset portion thereof which carries the arms 49 is, as will be understood, eccentric to the drum 45. By reason of the relative mounting of the shaft and drum the arms will be drawn into and projected from the drum as the latter is turned. The parts are so related that the arms will project their maximum from the drum at a point directly opposite the cleaning device 11. l/Vhen this point is passed, the direction of rotation of the drum being indicated. in Fig. 3, the arms or spikes will be drawn back into the drum, the outer ends of the arms or spikes being substantially flush with the pe riphery of the drum when said arms assume a vertical position. Beyond this position the spikes or arms are gradually projected outward. One end of the offset shaft 47 maybe squared to fit a correspondingly-shaped opening in the fram ework to prevent rotation of said shaft. As the spikes or arms are drawn into the drum it will be obvious that cotton cannot be carried around with the drum, the spikes being cleaned free of cotton as they are drawn into the drum.

In proximity to the top of the drum, as shown clearly in Figs. 2 and 3, there is a flexible vertically-disposed scraper or cleaner, as 50, which acts against the periphery of the drum 45 to clean the same, any dirt that may be detached therefrom falling against the cleaning device 11 and being drawn through the same by suction produced in the conduit 8. In the casing 6 and complemental to the concaved strip 35 is a c'oncaved strip 51. The two packing-strips 35 and 51 separate in an air-tight manner the spout 40 from the interior of the casing 6, so that when cotton enters the spout it cannot be drawn therefrom by suction within the casing.

In Fig. 1 I have shown the apparatus involving three feeders. This is not essential, for one feeder only might be employed, or I can use more than three, the number of them being of minor importance. The cleaners 11 are within the feeder-casing 6, and they eonstitute part of the feeding device and part of the elevating device.
