Abstract

The launching appts. is fixed to a column along which it is adjustable by a counterweighted pulley device. It consists of a hopper into which are fed the balls. Impetus of launch is given by a series of vanes driven by an integral variable speed motor through a flywheel. The mass of the flywheel allows energy to be stored sufficient to give rapid launching of the balls. Control is through a push button station connected to the appts. by a cable allowing remote operation. Orientation and azimuth are adjustable by suitable servo motors or rams etc.
