PEA-HULLER.

Specification of Letters Patent.

ratenteasept. 7, i909.

Application filed May 15, 1909. Serial No. 496,120.

To all whom it may concern:

Be it known that I, WILLIAM LAFAYETTE HAY, a citizen of the United States, and a resident of Franklin, in the county of Williamson and State of Tennessee, have made certain new and useful Improvements in Iea-Hullers, of which the following is a specification.

My invention relates to improvements in devices for hulling dried peas or similar articles, and it consists in the constructions, combinations and arrangements herein described and claimed.

An object of my invention is to provide a device of comparatively simple construction in which the hulling of picked peas or of peas on the vines may be accomplished by merely shifting the concave and feeding the peas through the device in the direction most suitable for their proper treatment.

A further object of my invention is to provide a concave made up of sections which can be readily taken apart to repair or inspect the teeth on the main cylinder.

Other objects and advantages will appear in the following speciication and the novel features of the device will be particularly pointed out'in the appended claims.

My invention is illustrated in the accompanying drawings in which similar reference characters indicate like parts in the several views and in which- Figure 1 is a side view of a pea huller constructed in accordance with my invention; Fig. 2 is a transverse sectional view of the device; Fig. 3 is a longitudinal section along the line 3-3 of Fig. 2; Fig. 4 is a side view of a portion of the device showing the fastening means for the concave in its shifted position; Fig. 5 is a section of a portion of the device similar to that shown in Fig. 2, showing the concave in its shifted position; Fig. 6 is a detail view showing the means by which the upper and lower parts of the concave are secured together; Fig. 7 is a side view of the cylinder, showing the arrangement of teeth thereon; and Fig. 8 is a sectional view of the parts of the concave.

In carrying out my invention I provide a main frame A consisting of side pieces a, end pieces a', the bottom member a2 and a top a3. Supported on the top is a hopper B of the shape clearly shown in Fig. 2, the bottom of the hopper communicating with an opening at in the top a3. On the side of the frame is another hopper or rather a chute C which is adapted to communicate with the concave as will be explained later.

Disposed longitudinally of the device on suitable bearings X and X is a central shaft S bearing a driving pulley P at one end. Secured to the shaft is a cylinder E which may be either solid or hollow. The cylinder is provided with teeth e set on its periphery in rows, each row being curved in the manner shown in Fig. 7.

The concave F is preferably made up in four sections. These sections are shown in Fig. 8. Each section is provided with rows of teeth f which are arranged to enter between theteeth e on the cylinder E as the latter is rotated on the shaft S. Two of the sections f and f2 are joined together by means of a semi-circular plate g at each end thereof while the other two sections f3 and f4 are joined together by a similar plate z, at each end. The plates g and It at each end are in turn connected by means of the extensions g on the plate g and the screws g2 which pass through these extensions and into the plate 71,. It will thus be seen that with this construction the removal of the screws g2 will permit the sections f and f2 which constitute half of the concave to be separated from the sections f3 and f* which constitute the other half of the concave.

In Fig. 3 are shown two end plates R and R, both of the plates having curved slots V and V respectively and the plate R being cut away at its lower edge to permit the entrance of a slide K as shown in Fig. 3. The upper slide L is of segmental shape and vis adapted to enter the slot V. It will be seen from the drawings that the opposed edges of the sections f and f2 are grooved at f6 while the opposed edges of the sections f3 and f are grooved at f7 to permit the entrance of the tongues Z and l: as shown in Fig. 2. The slides L and K may be pushed inwardly or drawn outwardly and constitute virtually a portion of the concave whenever they are in the groove. The screws M are arranged to enterl the curved slots V and V int-o threaded openings in the ends g of the parts of the concave. These screws are provided with wings m, and the thumb screws thus formed serve to lock the concave in its shifted positions.

From the foregoing description of the various parts of the device the operation thereof may be readily understood. In hulling picked peas the latter 'are placed in the hopper B. The upper slide L is then drawn outwardly in the manner shown in Fig. 3 thereby leaving an opening b through which the peas are fed. The rotation of the shaft S causes the Vpeas to travel from one end of the cylinder E to the other and since the Vteeth e on the cylinder E are set at such a distance from the teeth on the concave F as to permit the passage of the peas but toengage the hulls, the latter are torn from the peas. AAs the peas are hulled they pass out through the opening b2 left by pulling the slide K outwardly. If the peas are thoroughly dried, the slide K is pulled out to allow the peas to drop outv of the concave sooner than they otherwise would if the slide were pushed in to leave a smaller opening. If the peas are damp, the'slide K can be pushed in so as to cause the peas to travel farther but they are finally ejected from the machine` Y Now if the peas have been gathered without Y' being picked from the vines, a different mode of procedure must be adopted since feeding the vines into the vertical hopper would of course clog the machine up and stop its operation. yBoth the slides L and K are removed entirely from the device. The thumb screws M at each end of the machine are vloosened and the concave is rotated on the while the opening b2 is now brought on the opposite side of the machine. Now if the vines withtheir peas are fed into the chute C therotation of the cylinder E will cause the vines land the peas to be carried through the semi-circular bottom of the concave and they will passout through the opening b2. The peas will be not only stripped from the vines but will be hulled in passing through the machine.

It will be seen at once that the device can be easily converted by the simple operations described above in which the concave is rotated less than 90O from its original position. In actual practice it has been found that the peas may be hulled at a lower rate of speed of the cylinder than that required in the ordinary pea huller. Moreover only a small per cent. of the peas hulled are crushed in this form of device.

I claim: 1. In a pea huller, a frame, a plurality of feed receptacles carried thereby, a concave, a cylinder arranged therein, and means for shifting said concave to receive a charge from any of said feed receptacles.

2. In a pea huller, a frame, a hopper at therein, a slotted end plate secured to said frame at each end of said concave and a locking screw arranged to extend through said slots, said concave being adapted to rotate to receive a charge from the hopper or the side chuteand to be locked by said locking screws.

4l. In a pea huller, a concave consisting of hemispherical sections removably secured together and provided with teeth on Vtheir iny ner surface, each of said sections being provided with removable slides extending 'longitudinally of said concave and forming a portion of the wall of said concave, anda cylinder disposed within said concave and provided with teeth adapted to enter between the teeth on the inner surface of the concave.

5. In a pea huller, a frame, slotted end plates secured to said frame, a cylinder mounted for rotation on said frame and provided with teeth on its periphery, a concave disposed about said cylinder and provided with teeth arranged to enter between the teeth of the cylinder, said concave being provided withV longitudinal slots on its opposite sides, adjustable slides arranged to enter said slots, each of said slides constituting part of the surface of the slides, a hopper carried by the top rof the frame, a chute at the side of the frame and locking screws disposed in the end of said Yconcave and arranged to project through the slots inV said end plates thereby permitting the shifting of the concave to receive a charge either from said hopper or said chute and to lock the concave in its shifted position. 6. In a pea huller, a frame, a plurality of feed receptacles carried thereby, a concave, a cylinder arranged therein, and means for rotating said concave, to receive a charge from any of said feed receptacles. Y

7. In a pea huller, a frame, a hopper at the top of said frame, a'chute at the Yside of said frame, a concave, a cylinder arranged therein, and means for rotating said concave to receive a charge from said hopper or said chute.
