Abstract: A modular pedestal distribution hub includes a pedestal and a cover attaching to and covering a portion of the pedestal. The pedestal includes a first pedestal section and a second pedestal section. Each of the first pedestal section and the second pedestal section are configured to be attached to form the pedestal. The cover includes a front cover and a back panel. The front cover and the back panel are configured to be attached to form the cover.

Abstract: An antifriction force transmission, especially useful in torque wrenches comprises a freely rotatable cylindrical roller, opposed interface reaction surfaces in cooperative relation with the roller, and the roller and the reaction surfaces cooperating for effecting relative separating movement of the reaction surfaces when at least one of the reaction surfaces is caused to move transversely relative to the other of the reaction surfaces.

Abstract: A plunger has a perimeter for spaced cooperation with a guide bore along a reciprocation axis. For alleviating lateral thrust friction between the plunger perimeter and guide bore, antifriction roller structure has an axle with journals engaged in radius bearings on axis transverse to the reciprocation axis of the plunger. Mounting of the antifriction roller structure is such that annular wheel surfaces on the roller effect rolling engagement with the guide bore.

Abstract: A torque control mechanism for wrenches and the like in which a pivot block has one end rockably engaging a force tranmsission member, an axially movable plunger has one end rockably opposing a second end of the pivot block, a ball screw carried by the plunger has a control ball element engaging the second end of the pivot block, a balance cam carried by the plunger provides seat for a coiled compression spring having its opposite end engaged by an antifriction device permitting the spring to turn for adjustment purposes, a rotatably adjustable transfer screw engages the antifriction device and is threaded through a stop adjusting nut mounted in the distal end portion of tubular housing for the mechanism.

Abstract: An ajustable torque controlling mechanism has a drive shaft for driving connection with a member to be driven and a torque releasable clutch connected with the shaft and including a wear resistant torque sensitive ball detent release device and a compression spring rate adjusting arangement including radial arms on the clutch co-acting with generally ellipsoidal control edges carried by the housing surrounding the shaft.
