THEODORE A. PERRY, OF PLYMOUTH, NORTH CAROLINA.

COTTON-SEED CRUSHER.

SPEGIFICAI'IQN forming part of Letters Patent No. 320,682, dated June 23, 1885.

Application filed September 5, 1884. (No model.)

To all whom, it may concern.-

Be it known that I, THEODORE A. PERRY, a citizen of the United States, residing at Plymouth, in the county of Washington and State of North Carolina, have invented certain new and useful Improvements in Cotton-Seed Crushers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being'had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a side elevation of my invention,showing it attached to a cotton-gin. Fig. 2 is a cross-section of my i11- Vention on an enlarged scale; Fig. 3, a top plan View thereof with the hopper removed. Fig. 4 is a detail View in perspective of one of the supporting-brackets; Fig. 5, a similar view of one of the adjustable boxes, and Fig. 6 a detail view in perspective of one of the scrapers.

The present invention has relation to certain new and useful improvements in that class of devices for cotton-gins wherein is employed a pair of revolving rollers between which the seed passes as it comes from the gin and is crushed.

The object of the invention is to improve the construction of the device whereby it is adapted for attachment to any of the cottongins in common use, or may be used independent thereof, as found desirable.

The invention therefore consists in the details of construction substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanying drawings, A represents the hopper, arranged above the crushingrollers 13 C, said rollers having their hearings in boxes connected to end-supporting brackets D. The roller 0 is made adjustable, so as to increase or diminish the space between it and the roller B, which I attain by the employment of boxes consisting each of the two sections E F, having slotted extensions a, through which pass suitable screw-bolts, I), thus enabling the boxes of roller 0 to be set at the required distance from the boxes of the opposite roller. This adjustment of the roller is considered of importance in the class of de vices to which my invention relates, as not only regulating the pressure on the cottonseed to crush either fine or coarsefor different grades of fertilizer, which is frequently re- 5 quired, but the space between the rollers may be increased to such extent as to allow the seed to pass between them without being crushed, thereby obtaining the seed whole and uninjured when required for use in planting. The adjustment of the roller also enables the wearon the boxes and journals to be taken up.

It is evident that other means than those shown may be employed to render the roller adjustable without departing from the principle of my invention,the means described,however, being considered the most simple and practical.

Gear-wheels c d are connected to one end of the rollers B C, said wheels being of different diameters, with a different number of teeth, the wheel 0 being smaller than the wheel 61, so that the rollers will revolve at different velocities. This has a tendency to more perfectly and effectually crush the seed than were the rollers revolving at equal rates of speed, as, instead of simply flattening the seed, they are torn to pieces as they pass between the rollers.

The brackets D, which support the boxes and rollers, are cast with flange-plates e f upon their inner sides, as shown more clearly in Fig. 4, which are arranged at an acute angle to each other and have perforations g, for securing thereto, by suitable rivets or bolts, boards G, which form the chutes for the discharge of the crushed seed.

The brackets D at their upper edges are each cast with semicircular bearings h, for the journals of the roller B, and seats i, for the sections F of the boxes for supporting the journals of the roller 0.

The inner vertical edges of the brackets D are cast with outwardly-projecting clampingplates k, by which means the complete crushing attachment can be connected to the cottongin by suitable clamps, Z.

The scrapers consist of springs H,connected at their lower ends to the boards G, and at their upper ends have secured thereto longitudinal strips of wood m,faced on their upper edges with metal, as shown at n.

The wooden strips m, as will be seen by ref ence to Fig. 2, bear against the peripheries of the rollers B O, and as they will wear away much faster than the metal faeingsn, they will. always leave sharp edges to the facings, which will effectually remove from the surface of the rollers any particles of seed adhering thereto. The strips of wood prevent the unequal wear of the metal facing,as they bear at all times and with uniform pressure against the peripheries of the rollers, the springs allowing the scrapers to yield in order to prevent too rapid wear; and the pressure on the rollers of the scrapers may be increased or diminished by suit-able setscrews, p.

The rollers B C may be removed from their bearings and reversed to adapt the attachment to a right or left hand gin.

One of the rollers may be provided with a suitable pulley for connecting with the driving-belt of the gin, by which means the rollers are revolved; or when the device does not form an attachment to the gin, but is used separately and independently thereof, any well-known means may employed for imparting to the rollers the required motion.

It will be seen that the device is complete in itself, and can be used either as an attachment to the gin or separately and independen'tly thereof.

The brackets D, which are cast with the plates 6 f k, are ready for attaching the boards G thereto, and are readily secured to the gin by suitable clamps, these brackets being one of the essential features of the invention, and can be manufactured at a small cost.

Having now fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. In a cotton-seed crusher, two revolving rollers, a discharge-chute, and a suitable hopper, in combination with suitable supporting brackets for said rollers, which are cast with flanges upon their inner sides, arranged, as shown, for attaching thereto the eh ate-boards, and at their vertical'edges with outwardly projecting clamping-plates, for connecting the crusher to the cotton-gin, substantially as and for the purpose set forth.

2. In a cotton-seed crusher constructed substantially as described, the combination, with the rollers and scrapers, consisting of flat springs provided at their upper ends with wooden strips having their edges metal-faced, of suitable set-screws for regulating the pressure of the scrapers, substantially as and for the purpose described.

3. A cotton-seed crusher comprising a suitable hopper, two rollers, means for revolving them at different rates of speed, means for ad justing one of said rollers, brackets cast with fiangeplates and clamping-plates, the boards forming the chute, the clamps for the gin,and adjustable scrapers having at their upper ends wooden strips metal-faced at their edges, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
