SEED-COTTON CLEANER.

Specification of Letters Patent.

Patented Sept. 2, 1 EMS.

Application filed October 16, 1912. Serial No. 726,183.

To all whom it may concern:

Be it known that I, Mionaarr It. DAVIS, a citizen of the United States, residing at Kemp, in the county of Bryan and State of Oklahoma, have invented a new and useful Seed-Cotton Cleaner, of which the following is a specification.

The present invention relates to improvements in seed cotton cleaners, the primary object of the invention being the provision of a novel mechanism adapted to be disposed in connection with the exhaust or pressure fan used in connection with cotton machinery, the same being disposed to sepaate the dirt and trash from the air blast, such air blast being diverted from a strai ht channel into a circuitous passage, so that the heavier particles will be properly separated therefrom before the final exhaust of the air through the channel.

A further object of the present invention is the provision of a novel form of valve mechanism disposed in the air blast tube whereby the air may be diverted from the air blast tube directed through a circuitous passage and redirected into the air blast tube beyond the valve.

\Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a top plan view of the complete mechanism with the top removed. Fig. 2 is a section taken on line 2-2 of Fig. 1. Fig. 3 is a section taken on line 3--8 of Fig. 1. Fig. 1 is a section taken on line i i of Fig. 1 with the top in place. Fig. 5 is a view in elevation of one wall of the device showing the door for controlling the exit of the particles from the same. Fig. 6 is a similar view at the opposite side of the device showing the door to permit the cleaning of the device. Fig. 7 is a detail view of the air blast conduit at the portion adjacent to the valves and operating mechanism.

Referring to the drawings, the numeral 1 designates the base 01' floor of the machine which has mounted thereupon the four walls 2, 3, 4: and 5, which are sealed by means of the cap or lid (3. Disposed within the receptacle thus formed is a partition 7, which extends from the wall 2 to a point beyond theccnter and parallel with the wall 3, at which point a short partition 8 parallels the wall 4t and is connected thereto, and extends to and approximately the same distance from the wall 5 as the partition 7 is from the wall 3, a short partition 9 being disposed at right angles thereto and terminating to provide an inlet passageway between its free end and the inner face of the wall 2. Thus an air blast entering from the top at a point adjacent the wall 3 will follow the direction of the arrows Fig. 1 within the receptacle.

At the inlet end of the circuitous passage way formed by the partitions 7, S, 9 and 10 is an inclined wall 11, which forms a hopper for receiving the heavier particles, such as gravel, sand and the like first entering the chamber and provided in the wall 2 is the outlet aperture 152 controlled by the pivoted door 12, whereby the hopper 11 may be emptied.

In the rear wall l is provided a clean out aperture 13, controlled by a slide door 141-, this aperture being of sullicient size to, in large machines, permit the access thereto of a person for removing the cleaned seed from the machine.

The air blast conduit 15 is mounted as clearly shown in Fig. 4-, in the upper portion of the chamb f at one side thereof, in this instance paralleling the wall 53, the outlet 16 being exterior of the chamber, and the inner wall of the conduit having its inner end provided with the opening 17, the purpose of which will presently appear.

A curved metal plate 18 is (f(')llllt,(',l0tl to the inner end of the conduit 15 and is provided with the downwardly extending aprons 19 whose lower edges are curved so that the inlet conduit 20 connected to the aprons 11$) and curved wall 18 is in a plane at right angles to the conduit 15 and constitutes the inlet end of the air blast. The portion be tween the aprons 19 is normally open and therefore in order to provide a means which will close the same to permit the free access of the air from the conduit 20 between the aprons 19 and wall 18 into and through the conduit 15, a valve mechanism, as clearly shown in detail in Fig. 7, is provided. This.

the upper portion of the aprons 19, the cur vature of the valve 21 being of the same shape its adjacent curved portion of the lower edge of the aprons 19, as clearly shown in dotted lines Fig. 7, and in order to oper ate the valve 21 to move it from the position as shown in full lines to'dotted lines, Fig. 7 and vice versa, a crank 23 is connected to the rod 22. The valve 24: which provides a means for closing the aperture 17 and the remaining portion of the open part of theconduit formed by the aprons 19, has the curved end 25 for coaction with the curved valve 21 to close the opening formed by the aprons 19 while thestraight end 26 is disposed to be in the dotted position Fig. 7, to close the aperture 17, and thus permit the free access of the air blast throughthe inlet.20 between the curved wall 18, the aprons l9 and above the valves 21 and 24- and through the conduit 15. V

lVhen thevalves 21 and 2 1 are moved to the position, as shown in Fig. 1, the straight end26 of the valve 2st is disposed as a cutoff across the inlet end of the conduit 15, while an opening is formed between the ad jacent ends of the valves 25 and 21 to permit the entrance of the air blast though the inlet conduit 20 and downwardly in the direction of the arrow Fig. 4 through the various compartments formed within the chamber following the direction of the arrows as shown in Fig. 1, and finally entering the aperture 17 as indicated by the arrows in Fig. a. The heavier particles as shown in Fig. a will abut the curved end 25 of the valve 24 and will finally fall and enter the hopper 11, while the air with the lighter particles will pass through the chamber and finally through the apertures 17 and through the conduit 15, the seed falling in the casing. In order to impart simultaneous movement to the valves 21 and 21, a lever 27 is connected to the valve 24: and has a link 28 connected therewith and to the crank 23, as clearly shown in Fig. 7, so that as the valve 24 is operated to assume either the full or dotted line position, the valves 21 and 25ewill be moved into either the full or dotted line position. This lever 27 is projected through the top 6 so as to be readily accessible to the operator from'the outsi le of the machine. 7

*rom the foregoing description, taken in connection with the drawings, it is evident that the present device may be connected at the exhaust of fan or other pressure mechanism used in connection with the seed conveying blast from the cotton gin stands, and that. the heavier particles will be properly separated from the air blast by divertmg the same from one portion of the blast and directing it through the chamber as herein shown, and finally back into the conduit.
