JAMES MADISON KING, OF ROCHESTER, MINNESOTA.

WILD PEA AND OAT SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 325,093, dated August 25, 1885.

Application filed January 5,1885. (No model.)

1'' 0 all whom it may concern.-

Be it known that I, JAMES M. KING, a citizen of the United States, residing at Rochester, in the county of Olmstead and State of Minnesota, haveinvented certain new and useful Improvements in Wild Pea and Oat Separators and I do 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, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a vertical sectional view of my device. Fig. 2 is a side view of the same. Fig. 3 is a transverse sectional view of the main frame, taken through the bearings of a pair of opposite rollers. Fig. 4 is a top view of the machine.

The object of this invention is to provide mechanical means for taking wild peas out of all kinds of small grain and rice, and for taking oats and wild oats out of wheat.

The invention consists in the construction and novel arrangement of devices, as hereinafter set forth, and pointed outiu the appended claim.

In the accompanyingdrawings, the letter A designates an upright frame-work having at the top the hopper B, which feeds at one side of the frame upon the inclined board or guide 0. The mixed grain falls from this guide 0 upon the first inclined endless apron, D, which is operated by the rollers E and F, the journals of which are seated in suitable bearings in the frame. The inclination of this apron is low, being about fifteen or twenty degrees, or such that while the more elongated grains are carried upward by the apron the less elongated grains or wild peas will roll down the inclination and be discharged at the lower end of the apron. The grain carried upward over the head of the apron is discharged upon the guide 0, which is inclined at a higher angle than that of the apron,andfeeds the grain, with such wild peas or oats as may still be therein, uponfthe second endless apron, D,

which has an inclination similar to that of thefirst apron. The separation is effected by this apron in a similar manner to that hereinbefore described, the round or more spherical grains rolling down the inclination and being discharged at the lower end of the apron, while the more elongated grains are carried upward over the head of the apron. This endless apron is operated by the rollers E and F, which have their journals seated in bearings of the frame. Below the head of this apron is a third guide, 0, which has sufficient angular inclination to feed the grain to the next apron, D, which is provided with rollers E and F, and is also similar in its degree of inclination to the aprons D and D, and acts in a like manner. Thejournals of the rollers E, E, and E are provided with sprocket wheels or gearing, and are operated by belt Ito cause them to turn in the same direction and at the same rate of speed.

H indicates a pressurebar, which is pivoted at or near one end to the main frame, and is designed to bear against the belt I at its opposite end to insure engagement of the latter with the gearing of the roller-journals. Usuall. the guides G, G, and G are formed with upper shelves or ledges, K, which approximate a level, and hold the grain a little as it is discharged from the hopper and over the heads of the endless aprons, so that it will be fed upon the aprons in an easy and gradual manner. These guides are important, and are designed to give the mixture a slight impetus in the opposite direction from which the apron moves on receipt of grain. Each apron is provided with a rope, roll, or belt of cloth-such as a--attached to each edge. Each roller-has a groovesuch as b-around it near each end. Said rope, roll, or belt of cloth is made to run in these grooves for the purpose of guiding the apron and preventing any substance from rolling off sidewise. This is also important. Each apron is provided with a scraper against the bottom to detach any substance that may adhere thereto.

1 am aware that it is not new to provide a machine for separating peas with inclined endless carriers and guides adapted to receive the peas from the said inclined carriers and discharge them to the adjacent ones, and therefore do not claim such devices only in the specific construction hereinafter pointed out.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s

The improved pea and oat separator herein described, comprising the frame A, having at its upper end the hopper B, the upper guide beneath the same, the rollers arranged in two vertical rows at the opposite sides of the frame and formed with grooves near their ends, inclined endless aprons passing over the said rollers and having projections working in said grooves, the guides arranged over the upper ends of the inclined aprons and having their inclined portions extending between the said aprons and their ledges K approximately level, and suitable driving mechanism for said rollers and aprons, substantially as specified.

In testimony where'ofI affix my signature in presence of two witnesses.

JAMES MADISON KING. Witnesses H. A. EoKHoLD'r, G. A. FRIZZELL.
