ABSTRACT:
A telescoping pool cue or similar ball-striking device wherein a continuously variable amount of energy is stored. A main spring within an elongated handle is held in compression by a ratchet and pawl which provides an audible or visible signal of the amount of stored energy. A telescoping member may be marked with vernier indicia to visibly indicate the amount of stored energy or an electronic display provided. The main spring urges an outer plunger forwardly, but an actuator spring urges an inner plunger rearwardly. Upon release, the inner plunger moves rearward to release the pawl and ratchet after which both plungers move forwardly. This reciprocal action allows the cue to begin and end a stroke near the desired point of impact.
