Letters Patent No. 108,896, dated November 1,1870.

IMPROVEMENT IN COTTON-SEED HULLERS.

The Schedule referred to in these Letters Patent and making part of the same.

To whom it may'cmwern:

Be it known that I, WILLIAM R. FFE, of Cincinnati, Hamilton county, and State of Ohio, have invented a new and useful Improvement in Machines forHulling Cotton-Seed; and thefollowing is a full and exact description thereof, reference being had to the accompanying drawing and th letters marked thereon.

My invention relates to. that class of hullers which employ a horizontal cylinder and concave.

In the accompanying drawing- Figure l is a general view ot' my improved hnller, partly in section,

Figure 2 is a view of `the end frame.

Figure 3- i s a cross-section of my machine, showing the relative position ot' the cylinder and concave.

Figures 4 and 5 are cross-sections of cylinders, differing in their construction.

peculiar construction of the edge.

Figure 7 shows my'lcnife with its accompanying clamp.

Figure S, also a knife, showing the slots for its adjustment.

My invention consists- First, of the housing or end pieces, with peculiar shoulders to receive the segments of the concave; and

Second, of grooves, either 1n the knife or cylinder, orin the sectionof` the cylinder or the clamps for holding the knives, for preventing the necessity for diminishing the size of the cylinder as the machine wears, from the seed rolling against' the knives and thereby being cut.

My machine is so constructed that the housings or end pieces which support the axle or shaftyof the hori- -zontal cylinder also support the sections of the concave, and thus the two serve in part also as a frame.

These end pieces or housings are seen at A, and they are providedwith shoulders, A', for receiving the sections B, fig. 1', of thc concave, which sections also have .strong shoulders, B', for fitting the'housings.

These sections B are securely fastened tot-he housings by means of screws b, fig. 3.

By this construction the base-plate C and two sideboards, D, complete the frame ot' the machine.

Betweenv the sections or segments B of the concave are placed adj ustable knives, G, iig. 3, which are held in place by small screws, g, and also clamped-between the segment.

It will be observed that the concave only extends to the bottom of the cylinder, in order to give a freedischarge below, while the cotton-seed is fed in above.

My cylinder, as practically used, is of very peculiar construction, the same being partially hollow, and having clamps or sections for holding the knives in different positions, as may be desired.

It may be made thus:

Suitable disks or rings, F, made of wrought-iron, may be shrunk on the shaft M, tigs. Lt'and 5, for holding the knives G'.

A clamp, I, is placed under the knife, andv another clamp, I', on the outside of theknife.

Both ot' these clamps, and also thc knife, are fastened to the disks or rings F by means of .screws i.

The adjustable clamp under the knifehas a groove,

j, at ,its outer edge to receive the seeds and liold them for eutti n g 01 scalpin g off the seed. The rounded bottoms ofthese grooves keep clear,ot` matter thatwould pack in narrow angles and thus clog the machine. Similar grooves may be made in the edge of the knife, as seen at j, iig. (3.

rlhe knives are made adjustable by means of slots, g', iig. S, for inserting the screws, and the clamps areadjustablc in a similar `manner.

Ihe front edge ofthe clamp under the knives takes 'the principal wear, and as this edge wears off the clamp may be moved forward, and thus prevent the necessity of reducing the size otl the cylinder by turning it dow n in a lathe.

Instead of disks, z tbove-deseribed, a tubular core may be used, exftending the whole length of thejcylinder.

Having thus described my invention.

I claim-f f ll. Ihe'housing or end piece A, provided with shoulders A', substantially as set forth.

2. The segments B, in combination with the shoulders A of the housing, substantially as set fortl- 3. The knife G', when provided with the grooves j, as herein shown and described.

4. lhc knife G', in' combination with the adjoining grooved and adjustable cylinder' section or clamp, when said parts are arranged as herein shown and set forth.
