C/QJT'TON-HANDLING APPARATUS.

To all 207L015, it may concern.-

' Be it kn; wn that I, ALBERT F. TIDWELL, a citizen 971 the United States, residing at Celina, in the county of Collin and State of Texas, have invented new and useful Imprcivements in Cotton-Handling Apparatus, of" which the following is a specification.

This invention relates to certain new and useful improvements in cotton-handling apparatus, which apparatus involves means for elevating, separating, distributing, and feeding cotton and disposing of the seed from the cotton.

The main object of the invention resides in the construction and arrangement of parts whereby I provide for a continuous circuit of the cotton from the place of elevation through the various parts of the apparatus and back to the point of elevation, this arrangement providing for readily disposing of the overflow when the compartments leading to the gin-feeders have been filled.

Further objects of the invention relate to the novel construction of the seed-dropping mechanism and to details of construction involved in the various parts composing the apparatus, all as hereinafter described, and particularly pointed out in the claims followin the specification.

ln order that the invention may be clearly understood, I have illustrated the same in the accompanying drawings, in which Figure 1 is a view in end elevation of apparatus constructed and arranged according to my invention. Fig. 2 is a view in front elevation of a portion of the a paratus shown by Fig. 1. Fig. 3 is a detail View showing the lower end portions of the suction and overflow pipes. Fig. 4 is a sectional view, on an enlarged scale, showing the seed-dropping mechanism. Fig. 5 is a view, partly in section and partly in elevation, of the separator. Fig. 6 is a top plan view of the seeddropper, the upper part of the inclosing casin being removed. Fig. 7 is a view in sectional elevation of one of the compartments leading to a gin-feeder; Fig. 8, a section on the line 8 8 of Fig. 7; and Fig. 9 is a view in elevation of part of the device, illustrating a modification.

Referring now to the drawings, 1 indicates a suction-pipe, and 2 an overflow-pipe,which pipes are preferably connected together and are provided at a suitable point in their length with flexible joints 3 to enable them to be moved to different parts of a wagon 4, containing the cotton to be elevated. The

Specification of Letters Patent.

Patented. Dec. 19, 1905.

suction-pipe 1 is connected to a main conveyer or conduit 5, which leads to a separator 6. This separator may be of any preferred construction but preferably I employ the construction embodied in an application for patent filed by me April 4, 1905, Serial No. 253,886, except that I omit the lowerpart or chute described in said application. In lieu of this chute the lowerpart or chamber 7 of the separator into which the cotton falls after being cleaned communicates with a conduit 8, leading from a fan 9, whichforces air through said conduit, thereby creating suction in the chamber 7, causing the cotton to fall into and be conveyed along the conduit 8. Said conduit 8 leads to and forms the cotton-inlet into the first of a series of compartments 1O, 11, 12, and 13 for receiving the cotton, each of said com artments being connected at its lower en to the upper end of a ginfeeder 14, of any preferred construction and each of which compartments communicates with the compartment next to it in the same manner that the first compartment communicates with the conduit 8. In other words, the construction may be described as that of a series of compartments interposed in the length of the conduit 8, there being direct communication in a straight line through all of said compartments for the passage of air. Each of said compartments where it communi cates with the conduit 8 on the side facing the separator 6 is provided with an enlarged throat 14, and an inclined screen 15 projects from the opposite side of the compartment into this throat about midway the height thereof, so that a passage for the air and cotton is afforded both below and above the screen, as shown.

Each of the compartments 10 to 13 is provided, toward its lower end, with a dropvalve 16, controlled by an adjustable weight 17, mounted on an arm 18, fixedly secured to said valve. The valve 16 normally closes the outlet from the compartments 10 to 13, the weight being adjusted to hold said valve closed against the pressure of the air and also to cause said valve to withstand a certain weight of cotton. As soon as each of said compartments fills with cotton the valve 16 will drop and allow the cotton to fall into the feeder 14, and the valve may then remain open during all the time the cotton is being elevated, as it is only necessary that the valve should be closed when first starting the operation. Said valve, however, may be arran ed to automatically close after dropping t e weight of cotton, if desiredthat is to say, the weight may cause the valve to close after the cotton drops instead of the valve being held open after first-dropping the contents of the compartment.

In operation as the air forces the cotton fromthe separator 6 through the conduit 8 the air will pass through the screen 15 of the first compartment and so on through all of the compartments, while the cotton will strike on the under side of the screen 15 and drop into the compartment 10. As soon as said compartment fills the cotton will prevent the passage of air through the screen 15, and hence the cotton will follow the course of the air over the screen 15 and pass into the next compartment 11, which will be filled in the same way, and so on with the compart ments 12 and 13. It is necessary, however, to provide for taking care of the overflow of cotton after the compartment 13 has been filled, and to this end I provide a conduit 19, leading from the last compartment 13, which is given suitable return-bends to bring itover the place from which the cotton is to be elevated-say the wagon 4, where said pipe 19 is connected to the overflow-pipe 2. At the point where the overflow-pipe 2 connects with the return-pipe 19 I interpose a screen 20 in the pipe 19, beyond which screen I con tinue the pipe 19 in the form of an exhaustpipe 21, leading to the outer air. As the overflow of cotton passes through the con duit 19 it strikes the screen 20 and falls into the overflow-pipe 2, back into the wagon, while the air passes through the screen 20 and through the exhaust-pipe 21 to the outer air.

22 indicates a fan for creating the suction which elevates the cotton from the wagon 4, the casing of said fan communicating with the casing of the separator 6 by means of an air-shaft 23. The air-shaft 23 is located, of course, on the suction side of the casing of the fan 22. On the forcing side of said casing I connect a conduit 24, in the horizontal length of which I interpose a seed-dropper 25, the conduit 24 being continued beyond the seed-dropper 25 in the form of a seed pipe 26, leading to the seed-house. As shown by Figs. 4 and 6, the seed-dro per comprises a pair of disks 27, connecte by wings 28, each of which has secured to and projecting from its outer end a flexible strip 29, that is adapted to impinge against the inner wall of the housing 30, partly inclosing said fan to form an air-tight connection. The disks 27 are mounted on a shaft 31, rotatably mounted in suitable bearings 32, provided in supports 33, secured on opposite sides of the casing and inclosing the seeddropper. As shown by Fig. 6, the disks 27 rotate in apertures formed in the opposite planesa' the walls of said casing, and in order to make t e air-tight connection the disks 27 are each prox ided with a peripheral recess 34, opening inward, and flexible strips 35 are secured to the edges of theopenings provided in the casing 30, wiri ch strips project into the recesses 34, and thus close the opening be- In operation the seed-dropper will be rotated by the current of air forced through the conduit 24 by the fan 22. Seed being conveyed by the auger to the seed-drop er will be discharged into the path of the air beneath the dropper and be blown by said air through the seed-pipe 26 to the seed-house.

39 indicates a suction-pipe forming a con tinuation of the conveyer-pipe 5, which may lead to the place of storage of cotton if the cotton is to be drawn from such source of supply instead of from a wagon.

By dispensing with the conduit 24 for blowing seed through the seed-pipe 26 it is obvious that I can also dispense withthe fan 9 and by connecting the conduit 8 to the fancasing 011 the fan 22 make a single fan serve for carrying out the operation of my apparatus. Such a construction is indicated in Fig. 9. The operation of the apparatus has been embodied in the above description, and it is only necessary to emphasize the fact that with my apparatus the cotton is continuously elevated, cleaned, and distributed, the overflow returned to the place from which it was elevated, and the seeds delivered to the seed-house.

My improved seed-dropper permits me to employ the same fan which creates the suction for elevating the cotton to blow the seed to the seed-house, as the air-tight construction of the dropper insures the discharge of the seed into the path of the air without impairing the force of the air-current.
