Abstract
One end of a throwing arm that is pivotally mounted on a frame and is equipped at one end with a football holder. Two propulsion springs are attached to the other end of the throwing arm and extend to a cocking arm that is also pivotally mounted on the frame. The common pivot axis for the two arms is located adjacent to one end of the cocking arm and between the ends of the throwing arm adjacent the springs. In operation, the throwing arm is latched in a "ready-to-throw" position generally parallel to the intended direction of flight of the football. The cocking arm is pivoted into and latched in a position in which the springs are extended so as to exert a biasing force on the throwing arm. The throwing arm is released and the springs pivot the throwing arm and the ball holder forwardly in an arc. The football is propelled from the ball holder by the centrifugal and tangential forces imparted by the pivotal motion of the holder, without any impact that arrests movement of the holder.
