(under subclass 59) Subject matter including rows or columns of protrusions arranged about the rotor cylinder in a removable or integral formation.
(1) Note. The device may have protrusions in the form of spiketeeth, carried on the transverse bars of the rotor cylinder, which thresh out the grain as they revolve through similar teeth in the concave; the protrusions may be of rasp-bar type which are transverse bars with grooved metal faces, threshing is done by the rasping action between the cylinder bars and the solid concave bars below the cylinder; the protrusions may be of angle-bar type which are spiral bars having rubber facing. They beat out the grain between the revolving cylinder bars and the stationary shelling plate or concave.
