Abstract
An adjustable socket wrench having a socket head at one end with a recess adapted to receive a socket handle at the other end. The socket head is formed with a plurality of arcuately spaced openings which extend entirely through said socket head, and a plurality of gripping jaws fit relatively closely within and extend through the openings. Means are provided to operatively connect the wrench housing and the jaws for moving the jaws either toward or away from each other thereby to accommodate and tightly engage varying size objects to be rotated by the wrench.

An adjustable socket wrench comprising:
- (a) a socket housing having a socket head at one end thereof with a recess adapted to receive a socket handle at the other end thereof, and including a threaded shank,
- (b) said socket head being formed with a plurality of arcuately spaced openings which extend entirely through said socket head,
- (c) a plurality of gripping jaws fitting relatively closely within and extending through said openings adapted to engage the exterior surface of a nut member,
- (d) means operatively connected between said housing and said jaws for moving said jaws either toward or away from each other thereby to accommodate and tightly engage varying size nut members to be rotated by said wrench, said means operatively connected between said housing and said jaws for moving said jaws comprising a plurality of actuator arms corresponding in number to said gripping jaws, with the leading ends of said actuator arms being pivotally connected to said gripping jaws whereby said axial movement of said actuator arms results in pivotally radially inward movement of said gripping jaws.
