Abstract
An adjustable closed-end wrench is adapted for rotating a threaded fastener. The wrench has a handle and a wheel housing located at a free end of the handle. An engagement wheel is arranged within the wheel housing, and has an inner periphery and an outer periphery. The inner periphery defines a fastener-receiving opening adapted for receiving the threaded fastener. The engagement wheel is mounted for selective one-way rotational movement relative to the wheel housing such that the fastener is rotatable in a clockwise or counterclockwise direction.
Claims18
An adjustable closed-end wrench adapted for rotating a threaded fastener, said wrench comprising:
- (a) a handle;
- (b) a wheel housing located at a free end of said handle;
- (c) an engagement wheel arranged within said wheel housing and having an inner periphery and an outer periphery, the outer periphery comprising a plurality of circumferentially-spaced gear teeth, and the inner periphery defining a fastener-receiving opening adapted for receiving the threaded fastener, and said engagement wheel being mounted for selective one-way rotational movement relative to said wheel housing such that the fastener is rotatable in a clockwise or counterclockwise direction;
- (d) a wheel-actuating gear assembly operatively engaging the gear teeth of said engagement wheel to actuate said wheel and thereby rotate the fastener;
- and
- (e) means for pivoting said wheel housing relative to said handle.
