Valentine's patent "relates to improvements in corn-shellers in which upon one shaft are mounted the driving-pulley, shelling-cylinder, a rotary blower, and a crank-disk containing a wrist-pin, whereby reciprocating motion, through suitable connections, is communicated to the sieve underneath, and is provided with a yielding concave hinged over the top of the cylinder, and the required pressure, as it extends down over one side of the cylinder, is attained by weights."
