Abstract
A device for manually rotating a shaft in a substantially continuous manner, the device having a coiled spring-like body having at least one and a half coils, a pair arms extending laterally from the ends of the body, each arm integral with one of the coils, and an extension handle coupled to the end of each arm. The extension handles can be telescopically adjustable if desired. Further, the wrench can be permanently mounted on the outer surface of a shaft to enable convenient rotation of the shaft without additional tools. Additionally, the shaft and wrench assembly can form a component of an electrical pressure switch or like apparatus.

A device for manually rotating a shaft in a substantially continuous manner, the device comprising:
- a coiled spring-like body having at least one and a half coils, said coils adapted to fit around a rotatable shaft;
- and
- a pair of arms extending laterally from the ends of the body in the same general direction, each arm integral with one of the coils, whereby a force applied in a forward and backward direction to one of said arms enables the device to rotate said shaft in a substantially continuous manner.
A rotatable shaft assembly comprising;
- a rotatable shaft having a cylindrical outer surface;
- a ratcheting spring wrench device mounted on the outer surface of the shaft, for manually rotating the shaft in a substantially continuous manner, the device having a coiled spring-like body with at least one and a half coils, said coils adapted to fit around said shaft;
- and
- a pair of arms extending laterally from the ends of the body in the same general direction, each arm integral with one of the coils, whereby a force applied in a backward and forward direction to one of said arms enables the device to rotate said shaft in a substantially continuous manner.
