ABSTRACT:
A tool capable of applying clamping forces or, alternatively, spreading forces to the surfaces of spaced apart articles. The tool includes an elongate tubular base at one end of which is removably mounted a tail stop which serves to impart both clamping and spreading forces to associated articles. Mounted at the opposite end of the tubular base is a boss which is internally threaded to receive the screw shaft of a traveler assembly. The traveler assembly includes oppositely disposed, force imparting members which coact with the tail stop in clamping and spreading operations. Movement is imparted to the traveler assembly by a ratchet wrench on the screw shaft. The traveler assembly may be additionally supported by a telescopic member in slidable engagement with the tubular base of the tool.
