PEA-THRESHER.

SPECIFICATION forming part of Letters Patent No. 600,794, dated March 15, 1898. A li ti fl d August 31,1397. Serial ITO-650,096. (N model.)

To aZZ whom it may concern:

Be it known that we,FREDERIoK W. MILLER and WARREN O.WILLrs, citizens ofthe United States, residing at De Witt, in the county of Arkansas and State of Arkansas, have invented certain new and useful Improvements in Pea-Threshers; and we do hereby 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.

Our invention is a pea-thresher; and the novel and advantageous features of the same are set out in the following specification and claim thereto attached.

In the accompanying drawings, Figure 1 is a side elevation of our invention. Fig. 2 is a top plan view. Fig. 3 is a longitudinal sectional view. Fig. 4 is a top plan view of the machine after the hopper has been removed. Fig. 5 is a detail view of the fan-blades.

Our invention is described as follows:

1 is the frame.

2 is a body.

3 is the drive-wheel.

4 is the pulley on the shaft 1 of the fan A.

5 is a bearing for the shaft of the fan, there being another bearing exactly similar on the opposite side of the body.

6 is the band.

7 is a dust-opening, there being a similar opening on the opposite side of the body.

8 are cleats between which the hopper 9 fits.

10 is the front incline, inclining backward and downward, throwing the peas upon the cylinder 11'. 12 is another incline extending backward and downward, throwing the peas upon the bottom 13, from which they are drawn by the hand or small rake into the opening between the two inclines, whence The cylinder cry with teeth 14, which pass between corresponding teeth 15 in the concave base 16. Attached to the front end of concave base 16 is a concave perforated plate 17. Said concave base has attached to its lower end and rear side a wing 18, and said base 16 is pivoted in place by means of screws 19, which pass through the body of the frame and into the perforations 20 of said base.

Under the cylinder 11 and at the front end of the machine is an incline 21, which leads down to an opening 22, and just beyond said opening is another incline 23, which leads down to the bottom of the body.

The object of having the base 16 pivoted, as described, by means of the screws 19 is to adjust the base so as to accommodate the machine to large or small pea-pods, as they do not always grow the same size, being larger some years than others and growing larger on some soils than on other soils the same year. I

When the lower part of the base is thrown forward, the space between its. upper end and the periphery of the cylinder 11 is greater and allows a larger pea-pod to enter, and when so adjusted the rear end of the wing 18 is thrown a little down and gives greater force to the current of air produced by the fan, and at the same time the forward edge of the perforated plate 17 is thrown a little up and diminishes the space between its inner upper periphery and the periphery of the cylinder, and thus, though the current is a little stronger to blow out the hull, this position of the plate induces the pea with more certainty to pass through the perforations of the plate.

Immediately under theopening 22 is the spout 24, which discharges the cleanpeas at the side of the machine.

The construction of our fan we believe to be entirely new. It consists of. the shaft 1, the pulley, and the two sheets of

metal

25 and 26. 25 has

recesses

27, and 26 an opening 28. Sheet25 is bent at the dotted line 29 at right angles, and sheet 26 is bent at rightangles on the line 30. Then the part or'neck 31 is passed through the opening 28, and then the shaft 4 is passed in between the neck 31 and necks 32, and thus the fan is complete without the use of a nail or a screw to put the wings on the shaft. The shaft may be either square or round.

The operation of the pea-huller is apparent.

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

The combination of the frame 1, body 2, hopper 9, band-wheel 3, cylinder 11, having teeth 14; adjustable concave base 16, having IOO teeth 15; wing 18, secured to the lower end and front face of the base 16; perforated concave plate 17, secured to the lower end and rear face of concave adjustable base 16; hand 6, pulley 4, fan-wheel A, and discharge-spout 24, substantially as shown and described and for the purposes set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
