4 Claims.

This invention relates to pea viners for separating peas from harvested pea vines.

Such machines ordinarily include an elongated, slowly rotating, substantially horizontal drum and an included rotary beater by which the peas are removed from the pea laden vines during passage thereof lengthwise through the drum. In the main, such machines are quite satisfactory in that the peers are removed, without damage, from the vines, but they are not thorough in their action and frequently require repassage of the vines therethrough in order to recover all of the peas. An object of the present invention is to im prove such machines by the addition ofmeans efi'ective to insure complete removal and recovery of substantially all of the peas in one passage The pea viner selected for illustration includes a conventional elongated drum Ill having end rings, one of which is shown at H, supported on the usual rollers l2, and slowly rotated clockwise (Fig. 2) in a well known manner by conventional mechanism not shown. The drum shown also includes the usual relatively wide longitudinal bars l3 rigidly connecting the end rings II and constituting supports for the conventional peripheral screens l4 through which the removed peas escape into an appropriate receiver ordinarily arranged beneath the drum.

Included within the drum I is a conventional beater comprising a hexagonal rotor I5, which extends axially through the drum, and which is supported and rotated in a Well known manner through appropriate end trunnions, one of which is shown at l6 journalled in an appropriate support H. The rotor I carries a series of conventional paddles or beaters l3 which project from the faces thereof and which are slightly inclined, as usual, with respect to the longitudinal axis of the rotor.

In machines of this type the rotor i5 is ordinarily driven in the same direction but much faster than the drum Ill, the vines being lifted by the shelf-like bars I 3, as the drum rotates, and permitted to fall by gravity toward the rotor, and during their fall they are beaten or batted about by the heaters ill in a manner to remove the peas therefrom. This process continues as the vines pass slowly through the drum, the ad- Vance thereof through the drum being brought about by the above noted inclination of the heaters l8 with respect to the axis of the drum. The removed peas escape through the screens l4, and the vines ultimately emerge from the drum through the end ring II.

The structure and function of the parts thus far described are old and well known in the art. As above noted, the present invention makes provision for the effective removal of any peas which may not have been removed by the ordinary beating process during passage of the vines through the drum. In the machine shown, this is accomplished by means preferably such as will now be described.

The means shown for this purpose includes a series of auxiliary bars l9 fixed to the inner periphery of the end ring II and extending outwardly beyond the same. The auxiliary bars l9 are preferably so arranged as to form extensions of the bars l3 although their function is quite different from that of the latter. The projecting ends of the bars H! are encircled by a cylindrical screen 20 of a diameter substantially less than that of the drum, the screen being attached to the bars.

In the device shown, the end series of paddles [8' have been extended through the end ring. ll so as to render them substantially coextensive with the bars 19, and they coact with the bars to loosen and tear apart the mass of vines passing therebetween and to separate the remaining peas therefrom. To enhance this action, each extended paddle I8 is preferably provided along its outer edge with a series of outwardly projecting prongs or teeth 2| which pass rather close to the several bars l9 during rotation of the rotor [5 with respect to the drum.

A series of ribs 22 are also preferably provided on the inner periphery of the end ring ll, these ribs being inclined with respect to the axis of the drum in such manner as to shed from the ring any peas that might otherwise find lodgement thereon.

Various changes may be made in the embodiment of the invention hereinabove specifically described without departing from or sacrificing the advantages of the invention as defined in the appended claims.

I claim:

1. In a pea viner the combination of a rotating drum having a discharge outlet at one end thereof, means carried by said drum for lifting and dropping pea laden vines during passage thereof through said drum, a rotor disposed axially of said drum, beaters carried by said rotor for removing peas by impact from the falling vines within said drum, a circular series of bars extending lengthwise through said outlet at the inner periphery thereof, and members rotatable with said rotor and radially extended to provide a relatively narrow working clearance between said members and bars, said clearance being of an order to effect removal of peas from said vines by a stripping action.

2. In a pea viner the combination of a rotating drum having a discharge outlet at one end thereof, means carried by said drum for lifting and dropping pea laden vines during passage thereof through said drum, a rotor disposed axially of said drum, beaters carried by said rotor for removing peas by impact from the falling vines within said drum, a circular series of bars extending lengthwise through and beyond said outlet at the inner periphery thereof, and members on said rotor extending through and beyond said outlet, said members being arranged to provide a relatively narrow working clearance between said members and bars throughout the length of the latter, said clearance being of an order to effect removal of peas from the vines by a stripping action.

3. In a pea viner the combination of a rotating drum, a ring forming a discharge outlet at one end of said drum, means carried by said drum for lifting and dropping pea laden vines during passage thereof through said drum, a rotor disposed axially of said drum, beaters carried by said rotor for removing peas by impact from the falling vines within said drum, a circular series of bars extending lengthwise through and beyond said ring at the inner periphery thereof, a screen encircling the projecting portions of said bars, and members on said rotor coacting with the projecting portions of said bars to remove peas from said vines after passage of the latter through said outlet, said members and bars being relatively positioned to provide a relatively narrow working clearance therebetween of an order to efiect removal of the peas by a stripping action.

4. In a pea viner the combination of a rotating drum, having a discharge outlet at one end, means carried by said drum for lifting and dropping pea laden vines during passage thereof through said drum, a rotor disposed axially of said drum, beaters on said rotor for removing peas by impact from the falling vines within said drum, a circular series of bars projecting lengthwise through and beyond said outlet adjacent the inner periphery thereof, a screen encircling the projecting portions of said bars, members on said rotor coacting with said bars throughout the length thereof to remove peas from said vines after passage of the latter through said drum, and longitudinal rows of radially projecting fingers on said members disposed to provide a relatively narrow working clearance between said fingers and bars of an order to effect removal of the peas by a stripping action.
