PATENT GEFICE.
l JOI-IN DU BOIS, OFV GREENSBROUGH, ALABAMA.
,IMPROVEMENT IN COTTON-cms.
Specification forming part of Letters Patent No. 6,998, dated .Itnuary 8, 1850.
.To @ZZ whom it may concern,.- e
Be it known that I, JOHN DU Bois, `of
Greensborough, in the county-of Greene and State o' Alabama, have invented a new and useful Improvement on the CottonGin; and I hereby de declare that4 the following is a full, clear, and exact description, reference beinghadtotheaccompanying drawings,forn1 ing a part of this specification, in which- Figure lis a vertical sect-ion showing the inside of thel machine. Figure .2 is a perspective view showing the saws projecting Athrough the spaces between'the 'back ribs.
Fig. 3.is a front perspective view of the saws andthe ribs.
.The same letters of reference indicate like parts on all-the gures.
The nature of my invention consists in providing an auxiliary set of ribs,between-which the saws passtwice after passing through the `ribs in the roll-box, to separate metes, &e.,
from the' cotton in a separate chamber from thatin which the seeds are separated from the cotton. x
' Io enable others skilled in the art to make and use my invention, I will proceed te describe its construction and operation.
l The machine is nearly built in all respects like the commen cotton-gin, with the exception of the auxiliary set of ribs to remove the metes, and a separate chamber to receive them, from which they are removed bya revolving brush.
A is the frame, built in any of the known ways. i
B is the hopper er roll box, into which'the uncleaned cotton is fed te the saws. .The quantity ef cotton is regulated by the swinging board C.
D are the saws. They are set and revolve in the usual way.
E E are a series of iron ribs. They are se- 'cured in any'suitable way at the lower end to a transverse beam, 4a; they extend upward with outer projections, b b, which are braced nearly against the back beard, d, of the rollbox, and then they extend back into the mote-chamber G. I will term the ribs from the projections b the back ribs, although they are formed in one piece with the front ribs, E. The back ribs, F, are formed each .with a horn, h, behind which they curve downward and are secured by screws or otherwise to the bed-plate f of the mote-chamber. The
outside ribs, E, are convex in the roll-box, andthe back ribs are concavein the motecham ber behind the horn h. By the form ofthe back ribs, F, the saws pass between them twice during every revolution, oncebetween them at the hornv h, and again when passing down at S. The spaces through which the saws pass between the ribs E are a little larger than the spaces between the back ribs. The saws in passing between theribs E drag in the cotton from the roll-box, and by this action (as is well known, separate' theseed from the cet-l ton, when the seeds fall down te the outside through the'channel Ag. After the seeds are thus removed, a quantity of .metes and other matter still adheres to the cotton, and for the purpose of removing such impuritiesv I employthe back ribs, F, placed in a separate chamber, divided bythe projections?) from the roll-box. The saws in passing through theback ribs at the horn removes a quantity of metes, Ste., and the cotton'is still further cleaned from such impurities in passing again between the ribs at S," after which it is taken from the saws by the brush J, and pushed out i'nto the cotton-loom through the'speut K'. The brush H removes the metes backward,and thus prevents them from accumulating and falling down between the ribs.
By the employment of the auxiliary ribs F l in the manner described a mostbeautiful and clean staple of cotton is produced.
lCommon cottongins that are new in use may easily and at little expense be furnished with my improvement, which is of great benet on that account.
Having thus described my invention, I claim N The back ribs, F, in combination with the front ribs, E, they (the back ribs) beingcon strncted with a horn or projection, h,each, bei
hind which they curve downward,`to allow the saws to pass twice betweenthe ribs to remove the metes and other impurities, in the manner substantially as described.
JOHN -DU Bois.
