Abstract: A toy workover rig modeling the kind used to service oil and gas wells. The workover rig includes a wheeled truck. An extensible mast is pivotally fastened to the truck. A remotely-controlled pivoting assembly is connected to the truck for selectively moving the mast from a horizontal, traveling position to a vertical, substantially perpendicular operating position. A remotely-controlled telescoping assembly is connected to the truck for selectively extending the mast from a retracted position to an extended position. A remotely-controlled hoisting assembly is connected to the truck for lifted selected objects within the mast.

Abstract: A wrench including an elongated body with a pair of primary socket members attached to the opposed ends thereof. Each of the primary socket members has a driven socket for holding and turning a nut. A sliding sleeve is slidably and rotatably positioned on the body. A retaining arm extends outwardly from the sliding sleeve and carries an extensible backup assembly. The backup assembly has a support bracket releasably secured to the retaining arm and carrier bracket suspended from the support bracket by at least one spring. The carrier bracket has a threaded aperture with which a threaded rod is engaged. A secondary socket member is attached to the threaded rod and has a backup socket for holding a nut in axial alignment with one in the driven socket.
