APPARATUS FOR HANDLING COTTON.

SPECIFICATION formingvpart of LettersrPatent N o. 362.041, dated April 26, 1887.

Application tiled September 23, 188e. Serial No. 214,379. (No model.) I

To all whom it nmy'lconcern:

Be it knownthani, Divin A. simon, a cui! zen of the United States, residing at Little Rock, 1n the Acounty of -Pulaski and State of Arkansas, have invented certain new and use- ,ful Improvements in Apparatus for Handling Qotton, of which the following is a specifica-I tion, reference being had therein to the accompanyiug drawings.

Thisinvention relates to improvements in elevators and cleaners, more particularly to those designed for handling seed-cotton; and .1t has for lts objects to convey the cotton from I ton foreign matter, such as dirt, dust, or other impurities.

71th these objeetsin view the invention consists of a pneumatic elevator-.provided with an I automatic valve'for receivingand discharging thecleaned material, and a cr1t-off,which may .also be automatic, for controlling thesaid val ve. .The invention also consists in connecting wlth the 'elevator two or more valves, with means for -controlling the quantity of cleaned material delivered to each valve, or entirely cutting oti the said supply from anyone or more of the said valves'without affecting the /other valves.

One means for carrying out myinvention that I have found advantageous I have illustrated in the annexed drawings, in which- Figure l is a vertical section of an elevator embodying my invention. Fig., 2 is a similar v1ew showing one means I employ to provide several points of deposit. Fig. 3 is a plan of a portion of Fig. 1 with the top removed. f

The pneumatic elevator-tube is designated by A; the exhausting apparatus, which iu 4o the instance shown is a fan, by the letter B.

Abox, C, which I call the cotton-box, for receiving the cleaned cotton, is located at some point-in the elevator-tube, preferably as shown,

and communicates at its upper end'with the said tube, `Which is enlarged on each Side of the said box to form a separating-chamber, D

that is, `the chamber is wider and extends above the tube over the said box C. An inclined deliector, E, projects into the chamber D from to the rearv of the box C, and

a source of supply to one Or more points of dg, posit, at thesame time separating rom e cotisso constructed as to be adjusted to close or leave partiallyopen, or wholly open, the rear cnd of the screen F, whichl forms a continuation of the tube A into the chamber D, and is located over the box G.

' From t-he lower end of.` the box C depends the valve G, which may consist of flexible material-such as cauvas-stiti'ened on two of its opposite sides in any suitable manner-foriuvstance, by boards H. At some point between 6o the box C and the vfan B, I locate the eut-off, which may consist of a slide, I, adjustable across the tubeA. The fan exhausts the air ,from the tube A, thereby causing the cotton to pass into the said tube from the source of supply, which may, if desired, be a wagon.

- However, before the cotton 'passes into the tube the force of the exhaust causes the stiff- `cned lSides of the valve to approach, as shown in dotted lines in Fig. 1 ofthe drawings, thus 7o closing the lower end of the eotton-box, the said 'valve being held in the said closed posi tion by the exhaust, the flexible portions ofthe valve sealing it against the admission of air from Without. The exhaust being in operation and the valve closed, as described, the cotton is carried through the tube until it reaches the screen and detlector, when the dirt 1 and the like will pass through the screen and to any convenient point of exit from the liuc, 8o while the cleaned cotton will fall into the receiving-box and upon the valve and be there retained.

. When it is desired to discharge the cleaned cotton, the cut-off is operated to close the passage through the tube, and thus stop the action of the exhaust without stopping the fan. When the draft is out oil, the air in the iue approaching the receiver rushes forward and out through the dischargingvalves G, so as to 99 blow or force out the cotton, which, if allowed to fall of its own`weight, would require the cut-ofi to stand closed for a longer period than is desirable. Cotton being light requires this assistance in falling, time. 'Then,whiletl1eairinthetubeapproacl1- ing the separator is losing its momentumrby escaping through the receiver, the air in the tube between the receiver and the cut-oft `,havi `Y ing no means of escape and h a'ving attained a 100 in order to economize ,high rate of speed by the action of the exhaust mechanism, will necessarily momentarily condense itself at the'cutoff, and will again immediately react before coming to a rest, as is evident. 4This momentarily reverses the draft through the .wire-cloth in such a manner as to blow off any lint and d ust that may have lodged against the Wire-cloth and eiiectually cleans it, and at the same time makes asecond puff of air through the valves, and thereby 21S- sists in the discharge of the cotton. At this point the tine is opened and thevacuum created, ai before.

It will be evident from the foregoing that the cut-off in the tube between the receiver and the exhaust mechanism is a very essential element of my invention, as upon it depends the immediate 'discharge of the cotton in the receiver and the effectual cleaning ot' the separating-cloth.

Without limiting myself to the exact construction and arrangement of parts shown, I claim;

1. In an apparatus forelevatng cotton, the combination of a pneumatic tube or flue, an exhaust apparatus, a valved receiver connected to the tube between its mouth and the exhaust apparatus, a deiector in the tube over the receiver for directing the material into the same, an automatically opening and closing valve attached to the said receiver, and a cut-off in the tube entirely closing the same between the exhaust apparatusI and the valved receiver, whereby the action of the exhaust apparatus upon the tube may be suddenly stopped and .a reacting puii of air created in front of the eut-oii' to accelerate the movement of the discharging cotton, substantially as described.

2. The combination of a pneumatic tube or fine, an exhaust apparatus connected to the tube, a valved receiver communicating with the said tube between its mouth and the said ,exhaust apparatus, a screen and deflector adjacent to the said receiver, and aeutofl in the ving therewith, a iiexible tube between the. exhaust apparatus and the receiver, whereby the action of the exhaust apparatus in the tube may be suddenly stopped and a reacting -puff `of air created in the tube in front of,the"cutoff to accelerate the discharge of the material in the receiver and clean. the screen over the same, substantially as described. u,

3. In an apparatus for elevating cotton and other materials, the combination of the pneumatic tube or flue, areceiver connected therewith, a valve attached tothe said receiver and constructed of flexible material, and stiffening devices for the said valve, substantially as and for the purposes described.

4. In an apparatus for elevating cotton and other matcrialsfthe combination of a pneumatic elevating tube or iiue, a receiver connected to the said tube, and a valve attached to the said receiver, constructed of iexible material, and 5 having stitiened sides and iieXible sides, substantially as herein shown and described.

5. In an apparatus foi' elevating cotton and other materials, the combination of the pneu,- rnatic tube or flue, a receiver connected to the said flue, a defieetor adjacent to the said receiver, a screen adjacent to the deflect'or, and

a iiexible valve having suitablestiff'ening dedischarge-opening to the receiver, allombined as and for the purpose specilied.

In testimony whereof I aiiix my si gnature i n presence of two witnesses.
