Abstract: An adjustable socket wrench has only two components, namely, a collet driver with movable jaws and a circumscribing adjustable sleeve. Positive detent positioning of the fastener engaging jaws is obtained by rotation of the adjusting sleeve which radially moves the jaws inwardly or outwardly without axial movement of any parts.

Abstract: A variable nut driver includes a multi-fingered collet with individual jaw faces at the free ends of the fingers and a ring connecting together all of the fingers at their other ends. The collet is contained within a tubular member secured to a handle. A flat thread follower within the collet has projections which extend between the fingers and through opposing elongated slots in the tubular member. The projections engage the inner thread of a rotatable sleeve surrounding the tubular member and collet at axially displaced positions. Rotation of the sleeve moves the thread follower and collet axially forward or back. As the collet is moved back the jaw faces extending past the open end of the tubular member are cammed toward each other. Conversely, as the collet is moved forward, the jaw faces move away from each other. Rearward movement of the sleeve is restricted by the position of the handle relative to the tubular member. This prevents the sleeve from becoming disengaged from the thread follower.

Abstract: An adjustable wrench has a drive shaft adapted to be turned by a conventional ratchet wrench. A housing is mounted on the output end of the shaft and three equidistantly spaced jaws are mounted between the shaft and surrounding housing. Cam surfaces are on the jaws and inside of the housing so that housing rotation in one direction will open the jaws and in the other direction will close them. A ratchet mechanism connects the shaft to the housing.

Abstract: The adjustable socket comprises a plurality of fingers pivoted by one end thereof to a socket body and enclosed within a partially rotatable shell covering the socket body. A spiral slot in the shell is engaged by a pin or the like extending from the body so that when the shell is partially rotated, the shell extends or retracts axially relative to the body portion thus opening or closing the distal ends of the fingers due to the engagement of the outer surfaces of the distal ends of the fingers with the curved inturned end of the shell. This shell and fingers can be detachably locked in the desired position. This enables the fingers to adjust in order to grasp or grip a nut or bolt within the size range governed by design parameters. A spring reacts between the shell and the body portion normally retracting the shell so that the fingers are in the widest position.
