ABSTRACT:
An adjustable socket has a number of selectable socket size openings available. It includes a drive member, an indexing collar positioned within the drive member, and an axially moveable drive core positioned within the drive member that is manually rotatable to different positions corresponding to the selected socket size openings. There are a series of teeth on the drive core and the drive core has a cam surface with guide elements. Jaw members mounted to the drive member to move laterally between fixed lateral positions upon rotation of the drive core, each fixed lateral position corresponding to a selected socket size opening. Each jaw member has a cam that engages one of the guide elements in the cam surface, so that with the drive core in a first axial position it is enabled to be rotated, thereby causing the jaw members to move laterally to a selected socket size, and in a second axial position the teeth of the drive core and the teeth of the indexing collar interlocked to be maintained the selected socket size.
