ABSTRACT:
A combination of cylinder bars used with a backing plate for mounting on different lengths of threshing cylinders. The cylinders used with different models of combines for the threshing of grain, chaff and straw. The combination of cylinder bars includes a forward cylinder bar, a reverse cylinder bar and a center cylinder bar. The center cylinder bar is characterized by having both a forward and a reverse tooth configuration. Also, the center cylinder bar may be of various lengths depending on the length of the cylinder. Opposite side portions of the backing plate are bent to match the threshing cylinder radius. The backing plate includes bolt holes to match bolt holes on cylinder flanges on the threshing cylinder. Bolts are used to secure the backing plate to the cylinder. The three cylinder bars are mounted on a top portion of the backing plate. The top portion of the backing plate includes bolt holes to match the configuration of the bolt holes in the forward, reverse and center cylinder bar. Bolts are used for securing the cylinder bars to the backing plate. The combination of using one length of the forward cylinder bar, one length of the reverse cylinder bar and a center cylinder bar of different lengths eliminates the need of having a large inventory of various lengths of one piece.
