COTTON-SEED HULLER.

To all whom it may concern:

Be it known that I, HARDY L. OATHEY, citizen of the United States, residing at Erick, in the county of Greer, Oklahoma, have invented certain new and useful Improvements in Cotton-Seed Hullers, of which the follow ing is a specification.

This invention has for its object a simple durable and efficient construction of cotton hulling machine, designed to prepare the seed cotton to enter the gin free from burs, dirt, sticks and other foreign substance, thereby greatly prolonging the life of the gin proper and producing other advantageous results hereinafter specifically set forth.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a side elevation of my improved cotton hulling machine. Fig. 2 is a top plan view thereof. Fig. 3 is a longitudinal sectional view. Fig. 4 is a detail perspective View of the feed plate.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, the numeral 1 designates the casing of my improved cotton hulling machine, said casing being separated from the breast 2 by means of the inclined slotted board 3 producing a series of ribs 3 Saws 4 are mounted on the shaft 5 in the framework 6 so as to project through the spaces between the several ribs 3" into the 'the top of the breast.

breast.

A feed bed 7 is mounted on a rod 8 in slotted bearings 9 in the breast, so that the said feed bed may be tilted to different inclinations or raised up and down to suit the requirements of feeding.

10 designates an apron which is provided with a series of transverse slats 11 and which is mounted on the transversely extending rollers 12 and 13 journaled in bearings 14 at The apron 10 is inclined, as shown, and extends into close proximity with the inclined board 3 at the upper ends of the ribs 3, with its lower stretch running in a straight line from the ribs for a purpose hereinafter described in connection with the description of the operation of the machine. The roller 13 of the Specification of Letters Patent.

Application filed July 25, 1907.

Patented June 2, 1908.

Serial No. 385,546.

to receive the seed cotton and carry it out to the gin proper, through suitable feeding means (not shown).

The drive shaft 20 of the machine is provided with a belt wheel 21 which extends around an idler 22 and thence over a pulley 23 on the shaft 24 of the shaft cleaning drum 18. Said belt also extends around the pulley 25 on the end of the shaft 5 so as to revolve the saws.

In the practical operation the machine receives the cotton, burs,seed and lint together and separates the seed and lint from the hulls or burs, the latter going out in front of the machine, and the seed and lint being caught by the saws and carried to the ribs and thence disengaged from the ribs and dropped in the suction fine and thence carried to the gin proper. The cotton, in the hulls or burs, just as it comes from the stalks, is fed over the breast against the adjustable feed bed 7, and moves upon the same into contact with the saws, the teeth of which are so formed as to readily take hold of the cotton and free it from the hulls, but in such a manner as to not cut or break the fibers or release the lint from the seed. As soon as the cotton comes in contact with the saws, it is carried to the inclined ribs 3 where it meets the reverse motion of the endless apron 10, which is revolved very rapidly and so agitates the cotton as to form a complete but fiuffy roll without the necessity of forcing a roll by heavy feeding which would increase the density of the roll, this being a very advantageous feature of my machine. Furthermore, it will be noted that the apron 10, by its motion prevents the machine from packing or choking and this is the main separating element of the machine, as all burs, stalks, and other foreign matter, are thrown back over the cottonin the roll and fall out in front, as the front of the breast 2 is entirely open and unobstructed between the apron and feed bed thereby leaving the seed cotton fiuffy and in proper condition to enter the gin proper. The apron 10 keeps the cotton in motion in the breast of the huller until tion with the accompanying drawing, it will be seen that I have provided a cotton hulling machine which is simple in construction and not liable to get out of order and which is an efficient agitator and separator of the burs and dirt, stalks and the like from the seed cotton, preparatory to feeding the seed cotton into the gin.

Having thus described the invention, what is claimed as new is:

1-. A cotton hulling machine, comprising a casing, a breast, a series of ribs separating the casing from the breast, a feed bed mounted in the breast, a series of saws mounted in the casing and projecting through the spaces be tween the ribs into the breast, an inclined endless apron mounted in the breast with its lower stretch running in a straight line away from the ribs, means for imparting a traveling movement to the apron, and means for driving the saws, the entrance opening or front of the breast being unobstructed between the apron and feed bed.

2. A cotton hulling machine, comprising a casing, a breast, a series of ribs separating the casing from the breast, a feed bed mounted in the breast, a series of saws mounted in the casing projecting through the spaces between the ribs into the breast, means for driving said saws, an inclined endless apron mounted in the breast with one roller located in close roXimity to the saws and ribs, and with its ower stretch running in a straight line away from the said ribs and saws, said a ron embodying a series of transverse s its, and

means for imparting movement to'the apron,

the entrance opening or front of the breast being unobstructed between the apron and feed bed.

3. A cotton hulling machine, comprising a casing, a breast, a series of ribs separating the casing from the breast, a series of saws mounted in the casing and projecting through the spaces between the ribs into the breast, means for driving the saws, an inclined endless apron mounted in the breast with its lower stretch running in a straight line away from the ribs, means for imparting a traveling movement to the apron, and afeed bed mounted in the breast and forming with the lower stretch of the apron an entrance opening for the front of the breast which is entirely unobstructed from the saws outwardly between the bed and apron, the apron being outwardly diverging with respect to the bed as a whole.

4. A cotton hulling machine, comprising a casing, a breast, a series of ribs separating the casing from the breast, a series of saws mounted in the casing and projecting through the spaces between the ribs into the breast, means for driving the saws, a feed bed mounted in the breast, an inclined endless apron mounted in the breast above the feed bed and embodying a series of transverse slats, the lower stretch of the apron running in a straight line away from theribs and the apron diverging outwardly from the bed as a whole, the s ace between the bed and apron being entire y unobstructed or unrestricted, and means for imparting a traveling movement to the apron.

In testimony whereof I afliX my signature in presence of two witnesses.
