ABSTRACT:
Apparatus (10) for launching spherical and disc-shaped objects (O) used in the practice or play of a sport. A launcher assembly (12) includes a constantly rotating arm (14) rotatable about a center pivot (P). An object to be launched is loaded into an inlet end (16) of the arm adjacent the pivot for the object to be drawn outwardly by centrifugal force toward an outer end (18) of the arm from which the object is released. The velocity of the object when it is launched is a function of the length of the arm and the speed at which the arm is rotating. A feed assembly (20) holds a number of homogeneous objects. A feed mechanism (100) of the feed assembly is selectively operable to feed the objects into the inlet end of the arm. A control panel (148) enables a user to remotely control operation of the apparatus, to control individual launches, or to preset an interval at which objects are automatically launched. A drive unit (24) includes a motor (26,26') for constantly rotating the arm. The motor's speed is controllable to rotate the arm over a range of speeds so to control the velocity of the object when it is launched.
