Abstract
An adjustable tool including at least two tool parts, each having a work engaging surface, the parts being interconnected such that the work engaging surfaces are relatively movable, an elongated rotary and reciprocal, threaded actuator operatively associated with a part such that upon rotation or reciprocation of the actuator, relative movement between the parts will occur, a tool base mounting the parts in the actuator and a clutch on the base and receiving the actuator for selectively engaging or disengaging the threads on the actuator, the actuator being substantially freely reciprocal within the base when the threads are disengaged to allow rapid relative movement between the work engaging surfaces to occur to effect rapid adjustment of the relative position of the surfaces, the actuator being rotatable when the threads are engaged to effect fine adjustment and/or the application of clamping force by the work engaging surfaces. Also disclosed is an improved clutch construction.
