SPECIFICATION forming part of Letters Patent No. 538,552, dated February 5, 1895. Application filed April 28, 1894. Serial No. 509,405. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY D. PERKY, a citizen of the United States, and a resident of Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Roll-Machines for Reducing Cereals for Food; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a front elevation of a machine embodying my invention.

Fig. 2 is a side View of same. Fig. 3 is a sectional view on the line m0c Fig. 2. Fig. 4 is a detail view of thereciprocating frame, and Fig. 5 is a detail view of one of the grooverolls and scraper or comb.

The object of this invention is to provide an upright reciprocating or wall machine for the reduction of food, and especially for the reduction of grain to shredded or threadlike form without detracting from the nutritive qualities and virtues thereof.

The machine consists of a frame A of elongated form, havinga back plate 13, and in connection therewith a reciprocating shredder slide 0, having a grooved roll and hopper and devices for operating the same.

The frame A with its elongated back plate is designed to be secured to a wall or upright in vertical position by means of suitable bolts or fastenings indicated at D. At the upper end of the frame are provided the pulleys E each carrying a rope F, one end of which is attached to the slide 0, while to its other end is connected the weight G. This weight is sufficiently heavy to balance the slide and to assist the working movement of the latter in the upward direction.

The slide 0, is provided with a frame consisting of side plates H, connected by transverse bolts indicated at (E, which form bearings for the anti-friction rollers b, which engage the rear surface of the back plate B. The side plates extend forward at the sides of the back plate, projecting sufficiently to provide bearings for the journals K of the eccentric levers L, said journals forming bearings for the shaft of the grooved roll or cylinder R, as indicated at 0. These bearings are eccentrically placed in the lever journals K, so that when said levers are turned downward by depressing the operatinglevers Z, which are connected thereto by links d, the grooved roll or cylinder R is moved away from the back plate B.

The cylinderR is formed with circu mferential grooves preferably of V-form, as indicated in the drawings. Upon it is supported the hopper N, the rear wall of which is made short at its lower end between the side walls to provide a feed way for the contents of the hopper allowing it to pass down along the rear upper surface of the grooved cylinder between the same and the back-plate B.

When the cylinder slide is drawn upward by means of its levers Z, or a treadle connected thereto, the eccentric levers L bring the cylinder B into engagement with the backplate, so that by its rotation thereon, the grain or other contents of the hopper is reduced to shredded or thread-like form. In the reverse or downward movement of the slide the feeding ceases, and the cylinder is moved away from the back-plate by the action of the cocentric levers. The amount of upward movement of the levers Z, is adjusted and controlled by means of the set screws e, on the side plates H, said side plates also carrying stop lugsf, which limit the downward movement of the main operating levers Z.

P indicates a removable pan or receiver which is connected to the side plates of the slide by means of its lateral arms p, which engage lugs q, of said slide or carrier.

V indicates the discharging comb the operating edge 1; of which is shaped to conform to the contour of the cylinder surface across which it extends in front, its small teeth eutering the grooves of the cylinder and cansing the threads of material brought around in said grooves to fall upon the receiver in shredded or thread-like form.

Having described this invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination of the circumferentially grooved cylinder and a sliding carrier therefor, of the vertical back-plate behind said cylinder, the disoh arging comb engaging said cylinder, the hopper arranged to discharge between said cylinder and back plate, and devices for operating said carrier and cylinder, substantially as specified.

2. The combination with the vertical back plate, of the reciprocating, adj nstable grooved cylinder arranged to move in contact With said back plate, the carrier slide, in which said cylinder is journaled, a discharging comb engaging said cylinder, levers for actuating said slide, and stops for controlling the movements of said levers, substantially as specified.

3. The combination with the carrier walls and the grooved cylinder of the eccentric le- HENRY D. PERKY.
