ABSTRACT:
A football is projected with rotation on its longitudinal axis, in the manner of a forward pass, when it is fed into the space between, and thereby gripped frictionally by, the laterally spaced, confronting surfaces of a pair of driven wheels which confronting surfaces move in a forward, football throwing direction but in planes which extend forward angularly to opposite sides of the line on which the football is projected, the planes forming an included acute angle with each other. The speed and direction of football rotation may be varied by adjusting said angular relationship, and the speed of forward projection of the football may be varied by adjusting the rotational speed of the wheels. By adjusting said confronting surfaces to a common plane and feeding a football into the space therebetween such that said surfaces grip the football below its longitudinal centerline, the football is projected therefrom with rotation on its transverse axis, in the manner of an end-over-end kick-off.
