- App1ication'fi1ed June 11,

The present invention relates to hull or burr extractors and'cleaners, one 'objectof' the invention being the provision of apparatus in which there is amaster unitto which 5 maybe added'auxiliary or additional-units for operating upon the different types of picked or roughly gathered'cotton, that'is to say, since cottonis not uniformly gathered due to labor,--climatic or other conditions,

this invention iselastic in design so-thatit may beinstalled as'complete, or additional units added as desired.

A further object of the present invention is the provision of apparatus of'this type which contains'many of the essential elements of my three patents granted April 16, 1929,being numbered 1,709,663, 1,709,714 and 1,709,715 respectively, the present structure, however, being so modified as to provide for increased facilities by making provision for two or morecompartments for extracting hulls or' burrs from "cotton and enlarging the area for cleaningit. I v

With the foregoing and other objects in view, which will appear as the description proceeds, the, invention resides in the com-; bination and arrangement of parts and in the details ofconst'ruction hereinafter described and claimed, it being understood that changes in the precise embodiment ofthe'invention herein disclosed can bemade within the'scope of what is claimed without departing from the spirit of the invention. In the accompanying drawings,

main apgin stand, the latter being shown diagrammatically; g n s Figure2 is a similar view of the structure LE shown in Figure 1 with an additional set of cleaning apparatusfor acting upon the cot-- ton;

Figure 3 is aviewsimilar to Figure 1 of an apparatus having addltiona-l hull or burr separating mechanism mounted therein' wit h a similar number of cleaning elements as shown in Figure 2.

Referring to the v pecially to Figure 1 thereof, the lint flue L v and gin flueF are disposed in the usual manperfor na dual office, in that conveyor15 de; 9

ner, thepresent mechanism being associated therew'ithand above the gin stand G. I

The niain'casing {l which carries the present mechanism is provided with inlet 5, which has'disposed therein the two feed rolls 6 directly above the star roller 7, there being provided in cooperative relation withthe star rolleragrooved plate or valve 8 which is -ad-' justable to or away from the star roller 7 and which is similar in construction to that shown no in my issued Patent No. 1,7 09,7 15, but in which the starroller 7 is preferably operated n a reverse directionyin fact the'structure so far described is similar to that shown in said patentg-Disposed within the casings so as to direct the cotton to betreated-inone of two directions is a valve 9, whichwhen wide open permits the cotton toenter the passagewayor duct 10 and there to be acted upon by cleaning rollers 11, 23 and 22, the cotton being delivered on top of 'roller 11, to bein turndeliveredto'rollers 23 and 22, tO be returned in reverse order over screens-L2 1, 25 and a and directed through'the apron or chute 12 tothe rol'lbox of gin (not shown) or othertplace of deposit, it'being'understood that the application and operation of the invention is not confined to a gin stand. -This portion of the mechanism is employed when the cotton is burdened only with light field trash and hulls in suchlimited quantitythat the .usual huller gin will idischarge them lnyorder to act upon cotton which" is excessivelylhully, or what is known as snaps or bollys, and thus remove them from the cotton, first having been acted upon by proper adjustment of the va'lveor plate 8 to theistar roller 7, the valve .9 is placed to :as-

jsuine the position shown in Figure. 1 -so' that I the material isjdireotedto the left: and is acted upon by the hull extracting -mech'a nism which includes the saw cylinder 14,41 spikedor' fluted stripper 16-, the-brush 1 9 "and" thespikedspiralconveyors 15 and 17,"which Car livers the'cotton' to the saw cylinder 14 trans-Y versely :of the machine and longitudinally of a the saw cylinder from each end to center; and conveying hulls, and remnant cotton by the Ioweror bottomside through conveyor box to its opening as in my former patent Where the remnant cotton and hulls are deposited on spiked spiral conveyor 17, which in like manner acts upon the residue of cotton and hulls from center to each end, so that when the hulls or burrs are finally delivered the loss of cotton is negligible. In this operation,a ,considerable portion of the shale,

leaf and field trash is separated from the cotton, and goes out with thehulls into chamber C Where same is passed-from the housing 4 by the conveyor 20. or other suitable .ole vice. Thisparticular hull separating mechanism is somewhat similar to that-shown in my issued patents referred 'to and is here posi tionedso that'the cotton, after being removed from the saw cylinder 14: by the brush 19,

will deliver it into the curvedfchute 21 and to V the cleaning rollers 22,23 and 11, and from whence shale, leaf ,or' other-field trash is re-. moved. and delivered through respective screens 24, 25 and a, into'the compartment 26 to be removed byr the conveyor 27 -or other suitable device. The clean cottonisthus carried upwardly by the cleaningrollers 22,

; and 11 to: delivery apron orchute 12.

. As before stated, Figure 1 is the main apparatus, but to provide an additional cleaning action' tothe cotton, the structureas illustrated in Fig. 2 is desirable, the refers ence' letters primed indicatingv similar ele- V ments described'forFig; 1, and in addition thereto achute or passageway 28, instead of being curved, is inclined, and directs the treated cotton to cleaning roller 29 by which it is'delivered to the respectiverollers '30 and 31 and thence through the chamber26 to the V cleaning rollers 22, 23 andll and out of the apron or chute 12.-v Disposed in cooperation witl' jccleaning rollers 29, 30 and 31 are screens 32, 33'and 3 1. Thetreatment of cotton, when diverted through channel-10?, is the same. in Fig, 2'as in Fig. 1, except that the cotton is carried on the topof rollers 11, 23',

22', 31- and30to ,roller 29 to be returned and cleaned over the screens '32, 885, 3st, 24f,

cooperating with brush 41, stripper 38, spiked spiral conveyors 37 over box or trough 37 and spiked spiral conveyor 39 over screen box or trough 40, to screen the cotton before hulls V or burrs are finally delivered into compartment C. The action of these parts is similar tothat inFigures 1 and 22 7 .What I claim is: j'

1 1'. A cotton cleaning apparatus comprising a casinghaving an inlet portion adapted to receivecott'on direetly from a distributor, feeder and breaker rolls in said inlet portion, a compartment'i'n said casing having inclined upperand lower walls, screen means in the "bottom of said compartment, a series of cleanthe valve is closed, and hull extracting mechanism. in the path of travel of the materlal from the inlet portion byway ofsaid passageway, and discharge means from the compartment substantiallyat thetop. thereof.

2; A cotton cleaning apparatuscomprising a casing having an inletportion adapted to receive cotton directly from a distributor, feeder and breaker rolls in said inlet portion, a compartment in said casing, screen means in the bottom of said compartment, a series of cleaning rolls in, said compartment over the-screen means arranged at'diiferent elevations with their axes-in an inclined plane to insure maximum sifting action, a duct below the inlet, portion communicating with the top ofthe compartment for passageof the cotton to the uppermost cleaningroll, a valve operable to'ope'n or close said duct, meansbelow the: inletportion providing a passageway leading to the lower end of the compartment whereby the cotton will pass to the lowermost cleaning. roll when the valve is; closed, and hull extracting mechanism in the path of travel-of the-cotton from the inlet portion by way of said passageway. In testimony whereof my hand.
