Description: |
| "A number of hollow cylinders are made to revolve horizontally upon gudgeons, and parallel to each other. They may be made of wood or metal; and each of them is to be furnished with a door near to one end, to admit the grain, or other article to be hulled. Iron balls, rounded pebbles, or other hard substances, are put into these cylinders, the friction of which against the grain, is to produce the intended effect.
The cylinders are to be placed in a frame near the ceiling of a room; there are to be holes in the floor above, and supply spouts, corresponding with the openings in the cylinders. The frame is hinged so that the ends of the cylinders having the doors in them, may all be lowered, to deliver the grain, &c., the balls, or stones, being prevented from falling out by means of a grating. A band is passed alternately above and below the cylinders, to cause them to revolve. What I claim as new, is, the mode of cleaning or hulling by means of revolving cylinders, in which the operation is performed by hard substances placed within them, as above described." (From the Journal of the Franklin Institute, Oct. 1829, pg. 250.)
