VILLIAM R. HILL, OF LITTLE ROCK, ARKANSAS.

PEA-THRESHER.

SPECIFICATION forming part of Letters Patent No. 635,482, dated October 24, 1899.

Application filed February 16, 1899. Serial No. 705,613. (No model.)

To ctZZ whom it may concern.-

Be it known that I, WILLIAM R- HILL, a citizen of the United States, residing at Little Rock, in the county of Pulaski and State of Arkansas, have invented certain new and usef ul Improvements in Pea-Threshers, of which the following is a specification.

My invention is a pea-thresher; and it consists in the novel construction and arrangement of its parts hereinafter set out in the annexed specification and claims thereunto attached.

In the accompanying drawings, Figure 1 is a longitudinal vertical sectional view of my invention. Fig. 2 is avertical cross-sectional View on the line at looking to the left. Fig. 3 is a front end view. Fig. etis a perspective Fig. is a face view of one of the screens.

My invention is described as follows:

1 is the framework.

2 is the hopper, which is provided with a bottom 3, which bottom extends about fourfifths longitudinally across the hopper, leaving an opening 4 for the peas to be passed down onto the cylinder 5. Secured to the under side of the bottom 3 and extending the full length thereof is a beam 6, provided with downwardly-extending pins '7.

8 are the side walls of the cylinder-house, and in this cylinder-house is secured a sheet of metal 9, provided with numerous perforations 10. This sheet of metal 9 forms a bottom for said cylinder 5 and its arms 5 and extends from the right-hand side of the frame nearly to the left-hand side, leaving, however, a space 11, through which the threshed peas may fall on the incline floor 12. This incline floor 12 inclines in two directionsto the front and to the leftand is so constructed as to empty the peas and hulls into the upper end 13 of the chute 13. The hopper 2 is hinged at 2, so that it may be thrown back when desired. The side walls 8 of the cylinder-house are each provided with a row of pins 8. The pins 5 of the cylinder 5 pass between the pins 7 and 8 as the cylinder is rotated, and thus the pea-hulls are broken into fine bits and the peas are shucked. The finer particles pass through the perforations 10 and down the inclines of the bottom 12, while the larger particles and the peas pass through the opento pass through.

ing 11 and all fall into the open end of the chute 13 and slide down in the direction of the fan-trough let. The chute 13 is provided with two wire screens 15 and 16. Each one of these screens is set in a heavy wire frame 17. The screen 15 is set immediately across the chute 13 and grooves 18 in the side walls and a groove 18 in the bottom. The meshes of this screen are large enough to allow the peas The purpose of this screen is to keep the hulls and trash from making their way down in the direction of the fan, particularly when the fan is not in motion.

The chute 13 is provided with an opening 19, through which the peas are intended to fall after they have been sufficiently winnowed. The side walls of said chute 13 are provided with two other grooves and 21. The groove 20 is below the opening 19, and the groove 21 is considerably above it in the opposite wall. In these two grooves rest the opposite ends of the gauze-frame 17. This sets the gauze 16 at a considerable angle across the chute 13 and guides the peas to the opening 19. The meshes in the screen 16 are so close that the peas may not pass through. The grooves 18 18 and 20 and 21 and the frames 1'7 are not absolutely necessary, as two strips of wire-gauze may be tacked in in proper position instead of being fitted in the groovesl The cylinder 5 is driven by a crankhandle or other means secured on one end of the axle 22, while on the other end of the axle is aband-wheel 23, which operates the fan 24:. The fan 24 is driven in such a direction as throws the chaff out of the front end of the chute, as indicated by the arrow 25.

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

1. The combination of the frame 1; hopper 2, having a bottom 3, four-fifths of its length, a beam 6 the entire length of the hopper and secured to its bottom; downwardly-extending -pins 7 secured in the beam 6; walls 8, each provided with a row of'pins 8; cylinder 5, journaled in said frame; pins 5', secured in said cylinder and adapted to pass between pins '7 and 8; perforated sheet 9, extending four-fifths the length of the hopper and leaving a passage 11; double-inclined bottom 12; chute 13, situated under said bottom and provided with a side opening 10; a screen 15, situated across the chute and a screen 16, having one end below the opening and the other above; a fan 24,-, operated in fan-trough '14, and adapted to drive the pea-hulls and trash oif through the front end of the chute, substantially as shown and described and for the purposes set forth.

2. The combination of the frame 1; hopper 2, having a bottom 3, four-fifths of its length, a beam 6 the entire length of the hopper and secured to its bottom, downwardly-extending pins 7 secured in the beam (3; walls 8, each provided with a row of pins 8; cylinder 5, journaled in said frame; pins 5, secured in said cylinder and adapted to pass between pins 7 and S; perforated sheet 9, extending fourfifths the length of the hopper and leaving a passage 11; double-inclined bottom 12; chute 13, situated under said bottom and provided with a side opening 19; grooves 18, 18, 20 and 2i; screens 15 and 16, situated across the chute and provided with wire frames 17 screen 16, situated in grooves 20 and 21; screen 15, situated in grooves 18 and 18; band-Wheel 23; and fan 24, operated by said band-Wheel and adapted to drive the pea-hulls and trash off through the front end of the chute, substantially as shown and described and for the purposes set forth.

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