Speccation of Letters Patent No. 33,040, dated August 13, 1861.

To all whom it may concern:

Be it known that C. B. HoRroN, of Elmira, Chemung county, State of New York, have invented a new and useful mprovenient in Machines for Hulling and Polishing Buckwheat for Market; and I do hereby declare the following to be a correct description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The same letter refers to the same part wherever it occurs.

,This application is a modification of an application on which a patent issued to me on the 28th day of August 1860, for new improved mechanism for hulling, pearling and polishing rice. rIhe accompanying drawing is in most respects similar to the one presented with that application. rlhe Figs. G, 7, 13,14, 15 and 16, being more particularly applicable to this case will be hereinafter particularlydescribed; but the others having been fully described in the case alluded to will not require to be again described in this application.

The nature of my invention consists in the improved device hereinafter described, for hulling buckwheat, to prepare it for market.

Referring to the accompanying drawing, A, marks theframe of the machine; B, the cylinder; C, driving pulley on same shaft with cylinder B; D, another pulley on the opposite end of the shaft, to drive fan F, by means of a band working over pulleys D,

and E U, the upper flexible concave of flexible corrugated steel plate; lV, lower concave of cast iron, with stone concave K fitted thereto. Both these concave pieces are concentric with the cylinder B.

To enable others to make and use my iniproved huller, l will proceed to describe more fully its construction and operation.

The cylinder is constructed of flint and stone;7 and is revolved on its axis by means ef any suitable power applied to pulley C. The ends of this cylinder, (see Fig. 16,) extend a short distance through cheeks a which nearly touch the outer surface of the cylinder; these cheeks allow free rotation. of the cylinder, and at the saine time prevent the escape and loss of grain. j rlhere are two concave rubbers U, and X, that are hung or supported by bolts or arms sliding in slots or grooves, for the purpose of rendering them self adjusting. The uppei concave rubber is held in a position concentric with the cylinder B, by springs pressing against its back, and is adjusted by screws, or other suitable devices, such as are represented at la, 7c. .It is made ilexible, so as to be self adjusting t0 suit any inequalities in feeding in the grain to be hulled. The lower concave rubber X, is of stone fitted in an iron plate WV, which is held in a position concentric with cylinder B, by means of an adjust-- ing screw I.

The grain is fed into the opening or hopper b, and before passing between the rubbing surfaces, is lifted and revolved in the direction of the doubled arrow, by the revolving cylinder B, upon which it falls, and is then carried around and between its surface, and the surfaces of the upper and lower concaves-receiving in its passage, the pressure of the elastic surface of U, which bears the grain against the surface of the stone cylinder B, whose rough exterior abrades the surface of the grains of buckwheat in its passage around, and so tends to hull and polish it for market. The grain is further acted upon by its passage between the stone concave X, and the surface of t-he revolving cylinder B, which subjects it to a still more severe polishing operation.

Having thus fully described my invention, 3. The combination of cylinder B, with 'LO What I claim and desire to secure by Letters the cheeks a, in the manner and for the purplate W, as and for the purpose specied. pose specified. l
