WILD-PEA MILL.

Specification of Letters Patent.

Patented Jan, 15, 19181.

Application filed .Tune 27, 1917. Serial No. 177,348.

To all whom it may concern Be it known that I, FRED E. Passnn, a citizen of the United States, residing at Wells, in the county of Faribault and State of lvlinnesota, have invented new and useful Improvements in VVild-Pea Mills, of which the following is a specification.

This invention relates generally to separators, and comprehending particularly improvements in a pea separator primarily de signed for separating wild peas from wheat.

The chief cl'iaracteristio of this invention resides in the provision of a separator of the above stated character wherein use is made of a pair 'of endless belts inclined transversely as regards its direction of movement, consequently, the round wild peas as separated from the wheat will roll by gravity to one side of the belts and in turn be conveyed into a suitable receptacle separate from the receptacle into which the wheat is deposited.

Furthermore, I contemplate, among other features, the provision of spouts for discharging the material from the hopper onto both of said belts, the discharge mouth of the spouts being designed to assist in pulverizing the wheat to an extent, thereby assisting in the separation of the peas from the wheat as the material to be separated is conveyed over the belts.

l Vith the above and other objects in view, the invention consists in the novel features, details of construction and combination of parts which will hereinafter be more fully set forth, illustrated in the accompanying drawing and pointed out in the appended claim.

Figure 1 is a side elevation;

Fig. 2 is a view similar to Fig. 1 showing the opposite side of the machine;

Fig. 3 is a front elevation;

Fig. 4. is a plan view;

Fig. 5 is a longitudinal sectional view;

Fig. 6 is a detail perspective view of the hopper and spouts, the hopper being partly shown in section showing the slide plate therein; and

Fig. 7 is a front view taken on line 7-7 of Fig. 3.

Referring more particularly to the accompanying drawings, in which like characters of reference refer to corresponding parts in the several views, 5 denotes a supporting frame generally comprlsing a base .6 to which is connected a pair of spaced standards 7 and 8 supporting in the upper end thereof a hopper 9. Secured to the inner face of the bottom 10 of the hopper is a metal plate provided with spaced longitudinally alincd openings 11 through which the wheat or the like material contained in the hopper is discharged, and a valve 12 is disposed in. the guides 13 of the plate for a transverse sliding movement, hence, upon the manipi'llation of the valve through the medium of the handle 1d, will control the discharge of the material through the openings 11 by the manipulation of the valve 12 to bring the openings 15 thereof into or out of registration with the openings 11 of the hopper. lvlanifestly, it is necessary that a pair of openings in the plate 10 and valve 12 be provided, for feeding the material through a pair of spouts 16 and 17 respectively.

Arranged between the spaced standards 7 and S in a transverse inclined plane and in superposed relation one to the other is an upper auxiliary table 18 and a lower auxiliary table 19, each of which has one of its de rails terminally provided with a slot 20 to permit of the supporting rollers 21 to be detachably journaled therein. The supporting rollers 21 have trained thereover an up per endless conveyer belt 22 and a lower conveyor belt The forward end of the upper auxiliary table 18 projects forwardly of the forward end of the lower auxiliary table 19 and the lower supporting frame at the rear end of the separator projects be yond the end of the upper frame for a purpose to be hereinafter more fully set forth as the description of the invention is pro ceeded with. The supporting rollers journaled in the rear ends of each of the auxiliary frames are journaled therein for rotary movement, and motion is imparted to these rollers through a sprocket and chain connection indicated by the character 2% and driven by training the chain over the drive gear 25, the latter being rotated by the crank handle 26.

The U-shaped frame 27 is secured exteriorly and to the spaced standards 7 and 8, in parallelism with the upper and lower auxiliary frames and the connecting strip 28 of the U-shaped frame extends beyond the forward end of both of the upper and lower auxiliary frames and supports a wheat discharge spout 29 and a pair of troughs 30 capable of discharging the peas into a separ rate receptacle as the material passes off of the conveyers. In accomplishing this purpose, it is necessary that the troughs be disposed at one end of the connecting strip 28, owing to the fact that as the peas become separated from the wheat they will gravitate to one side of the belt, owing to the inclination of said belt.

As previously stated, the sole object of this machine is to cause the separation of the wild peas from the wheat, and the wheat being of an irregular shape, will not gravitate transversely of the belts during the travel. of the latter, whereas, the peas being round, will necessitate some means for pre venting the latter from becoming displaced sidewise of the belts during the course of travel of the latter, and to this end, 1 provide on the face of each of the conveyers and longitudinally thereof a plurality of flexible strips 31.

One of the chief characteristics of this invention resides in the specific construction of the spouts l6 and 17, whereby upon the manipulation of the valve 12, the material from the hopper, as fed through the spouts 16 and 17, will be deposited simultaneously on both the upper and lower belts. To this end, the respective spouts 16 and 17 are arranged in spaced depending parallel relation one to the other and in a longitudinal plane with the belts 22 and 23, comprising a hollow rectangular housing 32 provided on its discharge end with a short curved leg 33 and a long curved leg 34:, the leg 3-3 accomplishing the feeding action of the material on the upper belt, while the material passing through the leg 3 is deposited on the lower belt. Necessarily, in accomplishing this operation, the long leg 34: extends rearwardly of the belt 22 and deposits the material onto the rear end of the lower belt 33. Provided on the confronting faces and at the discharge end of each of said legs are tangs 35 which serve to pulverize or scatter the material as it leaves the legs, to assist in the separation of the peas from the wheat.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of construction and the method of operation will be readily apparent to those skilled in the art to which lhe invention relates, and while I have described the principles of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device is merely illustrative, and that such changes may be made when desired as are within the scope of the appended claim.

What is claimed as new, is

A device for separating wild peas from wheat embodying a pair of superposed transversely inclined upper and lower belts, the upper belt at its rear end terminating short of the lower belt. and means disposed 7 above the rear end of the belts for simultaneously depositing the materlal to be separated thereon, and means carried by the latter mentioned means for pulverizing the wheat previous to the depositing of the same on said belts, and means carried by each of said belts for preventing any accidental lateral displacement of the peas from said belts.

In testimony whereof I affix my signature.

FRED E. PASSER.
