WVILLIAM WORTH JACKSON, OF BETHANY, LOUISIANA.

HULLER, CLEANER, AND SEPARATOR.

SPECIFICATION forming part of Letters Paterit No. 293,029, dated February 5 1884. Application filed June 16, 1883. (Nomodel) which the following is a full, clear, and exact description.

The object of my invention is to provide a simple, durable, and effective machine for stripping or clearing the hulls or pods from peas, beans, and the like.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sideelevation of my improved machine. Fig. 2 is acentrallongitudinal sectional elevation of the same, and Fig. 3 is an elevation of the reverse side of the machine to that shown in Fig. 1. Fig. 4 is an end elevation, showing the relative position of the outlets for the pods or refuse and for the peas or beans.

On or in any suitable main casing, a, supported on legs a or otherwise, I fix the case b for the thrashing or hulling cylinder 0, which is journaled suit-ably in case b to revolve there if desired, and armed with spikes or teeth a,

which revolve past or between the spikes or teeth I) of the stationary divided case b, the lower half of which latter case is in this example of my invention fixed to the main casing a, and the upper half being arranged to lift off with the hopper c for access to the cylinder c and the hulling'teeth b '0 when necessary to clean, adjust, or repair the parts; The

may be adjusted .to open or close its throat g, for feeding the peas, beans, &c., to the hullingcylinder and case as fast as desired, and as the cylinder 0 revolves in the direction of the arrow the peas from the hopper are carried quite around by the cylinder, which strips the hulls offand discharges most of them clear' of the machine through the opening it, made for the purpose in the side of case b, while the hulled peas or beans fall between the teeth I) c and through suitable openings, 1' at the bottom of case b, upon a sloping shaker or shoe, 71;, which is pivoted suitably to casing to at Z, and is alternately raised and let fall by an angular-or cranked shaft, m,journaled in a'casing, a, and while the peas roll down shoe k they receive the air-blast from a fan-blower, n,journaled by its shaft a in any approved case, 0, having suction-openings 0 at one or both ends for inlet of air to the fan, the airoutlet therefrom being arranged to direct the blast upon the shaker k, to drive off any hulls or light trash which may fall thereoufrom the case I), while permitting. the liulled and cleaned peas or beans to descend to a dischargespout, p, for delivery into any suitable receptacle.

It will be perceived by the arrow in Fig. 1 of the drawings that the peas orbeans are carried down to the bottom around to the hole 2', where the heaviest and finest matters-that is, the peas or beans with the broken pieces of the pods+are discharged, and the haulm or vine with the larger pieces of pods are then carried up to the opening It, where they are for the most part discharged beyondthe upper edge of the sieve. Any haulm or pods which pass the hole It will be again carried around, become more thoroughly broken up, and ultimately pass out at one of the openings h t. The peas or beans falling on the wire-screen shaker-shoe 7a are shaken, so that the dirt, dust, or other adhering fiiatter may be detached and caused to pass through the screen, and as they roll down the inclined shoe they are met by a blast, which carriesto and over the rear of shoe any pieces of pod or haulm which mayhavc passed through the opening 6 with the peas or beans. In this example I apply the driving-power by a hand-crank, q, on the shaft of cylinder 0, which has a beltpulley, 1-,

over which a belt, 8, travels to the pulley t on the shaft on to work the shaker 7G, and .at. the other side of the machine the large pulley a on the cylinder-shaft runs the belt 1;, which drives the small pulley w on the shaft 02-, for

imparting the necessary speed to the fanblower a.

If desired, the shaker k may be awire screen of suitable mesh to permit small heavy waste matters and dust or sand to pass free] y through ICO I 5 i may be built of any size or capacity desired.

it, to insure abet-tor separation and cleaning of the product. a

Instead of discharging the cleaned peas or beans from shaker 70 into spout p at the end of case a, I may extend the lower wall, 0, of the air-passage farther toward the case b and shortenshakerhand passitslower endthrough an opening in the bottom of the case a, near shaft m, for discharging directly from the shaker into any suitable vessel below it.

Thusconstructedandarranged,myimpro ved machine may be cheaply built, is well calculated for durability in use, and will effect a large saving in time and labor in preparing peas and beans for market, and the machine I am aware that it is not new to make the teeth of the rotary cylinders of thrashers to interlap with teeth on the concave; also, that the stationary case has been made in two parts, so that the upper may liftoff withthe hopper; also, that a slide-valve has been used in hoppers to regulate the feed; but

What I do claim as new and of my invention is In a pea or bean huller, the combination of the fan, the inclined sieve, the rotary toothed hulling-cylinder, and the stationary toothed case, the latter provided with an opening near the bottom-to intercept the smaller matters and discharge them on the sieve, and an opening at the side for discharging the vines beyond the end of the sieve, substantially as shown and described.
