SPECIFICATION forming part of Letters Patent No. 328,799, dated October 20, 1885. Application filed August 14, 1885. Serial No. 174,384. (No model.)

.To @ZZ whom, it may concern:

Be it known that we, J osErH A. McMULLEN and AUGUSTUS B. BLooDwoRTH, citizens of the United States, residing at Stephens Pottery, in the county of Baldwin and State of Georgia, have invented a new and useful Improvement in Machines for Thrashing Peas, of which the following is a specification, reference being had to the accompanying drawings.

Our invention relates to an improvement in pea-thrashers adapted to be run by handpower; and it consists in the peculiar construction and combination of devices that will be fully set forth hereinafter, and particularly pointed out in the claim.

In the accompanying drawings, Figure lis a side elevation of a pea-thrasher embodying our invention. Fig. 2 is a similar view of the opposite side. Fig. 3 is a vertical longitudinal sectional view.

A represents the frame, which is rectangular in shape, as here shown, and is boarded up at its sides and at one end to form a casing, B. On the upper side of the frame is a platform, C, having sides D. The rear side, D, is inclined, as shown, to form a feed-board for directing the peas into the opening E, where they are fed into a revolving toothed shaft F, the teeth of which pass between vertical depending teeth G, directly above said shaft and the horizontal bars H in a thrashing-chamber I at the upper rear end of the casing. There is thus formed a small receiving-chamber with grated bottom and sides. The horizontal grate H extends clear across the thrashing-chamber, and the material is combed first through the vertical teeth and then through the grate H, which also serves to doff or clear the teeth of shaft F on their upward course.

The shaft F is journaled in blocks K, secured to the frame, and is provided at one end with a pulley, L, and at the opposite end with a pulley, M. The bottom of the thrashing-chamber is formed by a forwardly and downwardly inclined board, N.

Just below the lower end of the board N is pivoted the inner end of a screen, O, which is inclined downwardly, and extends out beyond the front end of the easing, where it is suspended by a bail, P, that is supported on the outer end of a lever, R,which is fulcrumed in the front end of the casing, as at a. This lever has an inwardly-extending arm R.

S represents the driving-shaft, which is journaled in blocks S near the front end of the casing. To the center of this shaft is secured a tappet-wheel, T, the arms of which engage successively with the arm B ofl lever R as the shaft S is rotated, to vibrate the lower outer end of the screen.

On the outer end of the shaft S is secured a large driving-wheel, U, having a handerank, V, by means of which it may be rotated by hand-power. An endless belt, W, connects the wheel U with the pulley L of the toothed shaft.

Below the inclined board N,in blocks X, secured to the frame, is journaled a transverse fan-shaft, Y, having fanning blades or paddles Y. A pulley, Y2, is secured on the projecting end of the fan-shaft, and is connected by a crossed endless belt, b, with the pulley M on the toothed shaft.

A downwardly and forwardlyinclined board, Z, is located below the fan, and below the screen is located a downwardly and rearwardly inclined board, A, that extends to near the rear end of the casing, a space, d, being left between the boards A and Z. In the sides-of the casing are openings B', through which air passes to the fan.

The operation of our invention is as follows: The drivin g-shaft is rotated, which vibrates the screen and rotates the toothed shaft and the fan. The peas to be thrashed are fed into the thrashing-chamber, where they are operated upon by the revolving toothed shaft and the teeth and bars in the thrashing-chamber, and the peas are taken from the shells thereby and fall onto the board N, which directs the peas and shells onto the vibrating screen. The peas fall through this screen onto the board A and roll down said board to the rear end of the easing, while the shells fall off the lower end of the screen in front of the casing. The rotating fan produces a draft of air out through 2 I y 328.799 l l the casing between the screen and the board A', which Winnowsthe peas and blows allthe dust, parts of shells, and other foreign 'substances out below the lower end of the screen.

5 Handles D permit the machine to be readily transported from place to place.

Having thus describedour invention, fwe..

claim- The combination of the casing, the thrash- 1o ing-chamber, the depending vertical teeth,

the horizontal bars, and the toothed shaft a1*-`
