MISHAEL E. NORRIS AND JESSE L. NORRIS, OF TEMPLE, TEXAS.

COTTON-CLEQANERVAND GIN-FEEDER.

To all whom it may concern:

Be it known that-we, MISHAEL E. Nonms and JEssE L. 'NoRRrs,cit izens of the United States, residing at Temple, in the county of Bell and State of Texas, have invented a new and useful Cotton-Cleaner and Gin-Feeder, of which the following is a specification.

This invention relates to gin-feeding devices of that class which include mechanism whereby the impurities, consisting of pebbles, twigs, bits of iron-such as nuts, bolts, nails, or the like-as well as dust and fine impure matter, is separated from the cotton before the latter is fed into the gin; and the objects of the invention are to simplify and improve the construction and operation of this class of devices.

With these and other ends in View, which will readily appear as the nature of the inven within the scope of the invention may be re- I of non, twigs, and the likemay settle.

tion is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims;

In the accompanying drawings has been illustrated a simple and preferred form of the I invention, it being, however, understood that no limitation is necessarily made to the prethat changes, alterations, and modifications sorted to when desired.

In said drawings, Figure l-is a vertical sectional view of a combined cleaner and feeder constructed in accordance with the principles of the invention. Fig.2 is a side elevation of the same. Fig. 3 is a detail View of 'a portion of the adjustable toothed rock-shaft.

Corresponding parts in the several figures are indicated throughout by similar characters of reference. y

The casing 1 of the improved cleaner and feeder is supported for operation upon a ginstand of ordinary construction, thev upper 2 portion of which is shownat 2, said caslng being of any desired width, usually of the same width as that of the gin-stand upon 4 which it is placed for operation.v

The casing is provided in its rear part with i a flue 3, into which the cotton is fed. At the lower end of said flue is supported a roller.4, which is provided with longitudinal corrugations or indentations 5 into which heavy ob'ectionable materialsuch as pebbles, lfilts 1e Specification of Letters Patent.

Application filed August 14, 1905. Serial No. 274,131,

Patented March 5,1907;

1 rear wall of the flue 3, which forms a part of the casing, is bulged forwardly beneath the roller 4, concentrically with the latter, and is; then extended downwardly, so as to form 1 the back wall 4 of a chute 5, havingan inclined front wall 6, which likewise constitutes l a part of the casing. The casing further inl cludes a front wall 7, which is bulged to form suitable compartments for a pair of- rollers 8 and 9, the former of which is disposed i above and in front of the corrugated roller 4 and the latter of which is disposed in front of and beneath the plane of the corrugated roller 4 and somewhat in advance of the roller 8. The front wall 7 terminates at its j lower edge in a forwardly-inclined angular l lip 10, overhanging an opening 11 at the upl per edge of the front portion 6 of the casing, said upper edge being reinforced by a rib 12, with which an apron 13 is hingedly connected, i said apron serving to guide the clean cotton into the gin.

Secured transversely in the casing between wall of the casing is a beam 14, at the upper edge of which is hingedly mounted a shield 15, said shield being connected with a shaft or rod 16, one end of which extends through the end of the casing and carries a leverf handle 16, adapted to engage a notched segment 17, whereby the shield 15 may be secured at various adjustments. At the lower front edge of the beam 14 is supported a rock-shaft 18, which likewise extends vided with an adjusting-lever l9, engaging a notched segment 20, whereby it may be secured at various adjustments. The rockshaft carries a plurality of teeth 21, constituting a comb, which, as will be seen, is adjustable with relation to the roller 9. A curved screen 22, concentric with the roller 9, extends between the beam 14 and the reinforcing-strip 12, with both of which the said screen is suitably connected.

Motion may be imparted to the shaft of the roller 8 by means of a belt 23 from the source of power. The shafts of the rollers 8 and 9 are connected by a twisted belt 24, whereby they are rotated in the direction indicated 1 by the arrows in Fig. 1, and the shaft of the corrugated roller 4 has been shown as carryi ing a ratchet-wheel 25, operated by pawls l 26 27, connected with a'lever 28, which is connected by a pitman 29 with a wrist-pin i 30 upon a disk 31, secured upon the shaft of the rollers 4 and 9 and spaced from the back through the end of the casing and is prothe roller 8. It is to be understood, how ever, that other suitablegearing may be emphiyed for driving the several rollers.

n a spiral conveyer 32, the shaft of which carries a band-wheel 33, connected by a belt 34 with a band-pulley 35 upon the shaft of the roller 9, whereby the spiral conveyer is driven at a speed which will be regulated by the relative sizes of the pulleys 33 and 35.

In the operation of this device the seedcotton is fed into the chute 3 and drops on top of the corrugated roller 4, the upper lead of which moves in a forward direction. Heavy and objectionable material will settle in the corrugations or grooves of said roller and as the latter rotates will be discharged behind the shield 15 and be guided through the space or opening between the rear edge of the beam 14 and the rear wall of the cas- 1 ing into the chute 5, where it is disposed of .by the spiral conveyer 2-. The roller 8, 'Wlnch is designated the picker-roller, is provided with radially-extending teeth 36, which carry the cotton in an upward and forward direction, deliverin the same upon the roller 9, which is likewise provided with teeth 37. By the roller 9 the cotton is carried over the screen 22 to the outlet 11, where it is intercepted by the lip 10 and delivered upon the hinged apron 14, whereby it is conveyed to the gin.

In its passage over the screen 22 the cotton is freed from dust and other fine impurities, which pass into the chute 5 and are disposed of by the conveyer 32. The hinged shield 15 serves a twofold purposein forming a guide over which the coarse impurities may slide downwardly in the direction of the chute and also in serving to strip the cotton from the picker-roller in case. it should exhibit a tendency to adhere to said roller and delivering it upon the cleanerroller. The teeth of the latter in pulling the fibers of the cotton between the teeth 21 serve to straighten the fibers and to loosen the adhering dust, which will thus more readily be separated through the screen 22. This cleaning and feeding. device is provided with an automatic feed cut-off attached to the breast of the gin-stand in such a manner that the feed is stopped by lifting the breast of the gin, throwing the ratchet out of gear. to either friction or ratchet gearing.
