W. J. STEVENSON. DEVICE FOR SHELLING PEAS.

N0. 19,800. Patented Mar. 30,1858.

UNITED STATES PATENT OFFICE.

WM. J. STEVENSON, OF NEW' YORK, N. Y.

MACHINE FOR SHELLING- PEAS.

Specification of Letters Patent No. 19,800, dated March 30, 1858.

To all whom it may concern:

Be it known that I, IVILLIAM J. STEVEN- SON, of the city, county, and State of New York, have invented a new and useful Machine fo-r Shelling Peas; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1, is a side sectional elevation of my improvement. Fig. 2, is a plan or top view of ditto. Fig. 3, is anenlarged transverse section of the rollers and a portion of one of the endless cords showing clearly the operation of the above parts.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in the employment or use of rollers in connection with a series of endless cords, arranged substantially as hereinafter shown whereby the peas may be shelled and separated from their pods with the greatest facility.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents a rectangular ,box in the lower part of which a drawer B, is placed transversely, and C, D, are two rollers which are placed transversely at one end of the upper part of the box. At the opposite end of the box a roller E, is placed. The rollers D, E, are placed in the same horizontal plane and endless cords F, pass around them. These cords extend the whole width of the box and are placed at equal and suitable distances apart, see Fig. 2. The cords may be constructed of silk, hemp or any suitable material and the front roller D, may be grooved circumferentially to keep the cords in proper position and also to serve as a protection to the same. The rollers D, E, have their journals fitted in bearings which are capable of being adjusted horizontally by set screws (a). The roller C, is placed over the roller D, but the two rollers are in an inclined plane that is to say, the roller C, is placed a little farther inward or toward the roller E, than the roller D. The ournals of the roller C, are fitted in bea'rings which are rendered capable of verticaladjustment and whichmay be secured at any desired point by set screws (1)).

On each end of the roller E, a cam G, is placed, and on-these cams the inner end of a hopper H, rests. The hopper H, is placed in a slightly inclined position and is pivoted near its outer end to horizontal arms or projections (0), (c), at the upper part of the box A.

The operation is as follows: The peas to be shelled, shown in red are placed in the hopper H, and the roller D, is rotated in the direction indicated by the arrow by any proper means. The hopper is vibrated vertically by means of the cams G, G, and the peas are fed thereby from the hopper on the endless cords F, which convey the peas to the rollers C, D. The pods as they pass underneath the roller C, are depressed or forced down, the cords F, yielding and the pods will be split by the pressure and will be caught in the bite of the rollersand as the pods are drawn between the two rollers C, D, the peas will be stripped from their pods and owing to the position of the roller C, relatively with the roller D, the peas will be forced downward between the cords F, into the drawer B. The operation of the rollers C, D, is clearly shown in Fig. 2. It will be seen that the peas are stripped from the pods and repelled by the rollers in consequence of the obtuse angle formed by the bite, and as the pods are split they are compressed so that they will be caught in the bite of the rollers, while the peas, for the reason above stated will be repelled from them and forced down between the cords into the drawer B.

This machine has been practically tested and operates well. It will prove highly valuable where peas are raised in large quantities, and form a staple crop.

I would'remark that it is perfectly immaterial as regards the way the pods are presented to the rollers C. D. Those pods that are presented sidewise are split and have the whole number of peas they contain forced from them at once, whereas those that are presented endwise will have their peas forced from them consecutively as the.

pods are drawn between the rollers C. D. The implement will shell either green or dried peas.

I do not claim separately and broadly the employment or use of rollers, as separators for they have been previously used for such purposes, as for instance in the roller cotton gin, where the seed is stripped from the cotton by the same process as herein described. Neither do I claim broadly the employment of the rollers with an endless belt or carrier irrespective of the construc and endless cords F, arranged to operate tion of the same, and its arrangement with substantially as and for the purpose herein 10 the rollers, whereby the apron serves as a set forth. carrier for the pods and allows the shelled 5 peas to pass through it. STEVENSON What I claim therefore as new and desire Vitnesses: I to secure by Letters Patent is, v W. TUsoH,

The combination of the rollers C, D, E, W. HAUFF. a
