Adjustable socket including apertured sleeve

An adjustable socket comprising:

• a driver adapted to be rotatively driven about an axis of rotation thereof;
• a plurality of jaws each of which has a mounting lug including an enlarged end mounted on the driver for radial movement with respect to the axis of rotation thereof;
• each jaw also having camming and slide surfaces that are oriented in opposite axial directions;
• said camming and slide surfaces having a junction with each other which defines the outer radial extremity of the jaw;
• the driver having a jaw support end that engages the slide surfaces on the jaws;
• spring means for biasing the jaws radially outward;
• a sleeve that receives the driver and the jaws and is axially movable with respect thereto;
• said sleeve having camming surfaces that respectively engage the camming surfaces of the jaws to position the jaws against outward radial movement under the bias of the spring means;
• the sleeve having apertures respectively associated with the camming surfaces thereof;
• said apertures receiving the jaws at the junctions of the camming and slide surfaces thereof upon outward jaw movement under the bias of the spring means;
• and means for axially positioning the sleeve with respect to the driver.
