Abstract
Abstract A spring projector assembly is connected on a turntable mounted at one end of the playing surface of a pocket billiard table, the turntable being rotatable about a vertical axis and the spring projector mounted inclined toward the playing surface and rotatable about its longitudinal axis relative to the turntable. The spring projector includes a hollow tubular body with a spring-loaded piston therein, the piston head having a plurality of annular grooves on its surface selectively engaging with a trigger release mechanism for selective loading of the piston spring. The piston rod protrudes from the end of the hollow tubular body adjacent the playing surface and the protruding end portion is offset from the axis of the piston rod and terminates in a cue ball engaging tip rearwardly of a ball holding impression disposed within a slot in the turntable. The portion of the tubular body in which the piston head is disposed comprises a compression chamber having plural holes through the sidewall thereof, the selective covering of which impedes the forward thrust of the piston rod ball projector upon release of the spring-loaded piston by the trigger.
