Abstract
A drive sprocket wheel of the type having drive chain link receiving pockets formed between the sprocket teeth and a circumferential groove dividing each tooth into a pair of tooth sections with the outer tips at the flanks or sides thereof being cupped for the reception of the horizontal chain links, is improved by sloping the cupped outer tips toward the running direction of the chain. In the sloping direction, the outer portions of the flanks may be flat and are followed by concave surfaces. The sloping flanks of each pair of toothed sections establish theoretical points of contact with the rounded horizontal chain links during the drive operation, such points lying about midway between opposite sides of the sloping flanks.
