Abstract: A ratchet wrench is provided comprising a wrench handle with a head. A ratchet member has a plurality of ratchet teeth and is seated in the head for rotation about an axis. A pawl disposed within the head is adapted to pivot relative to the ratchet member. The pawl is provided with first and second pluralities of pawl teeth disposed for movement into and out of engagement with the ratchet teeth. A selector mechanism selectively pivots the pawl to move a selected one of the first and second pluralities of pawl teeth into engagement with the ratchet teeth. In one example, the selector mechanism can selectively permit the ratchet member to perform at least three functions.

Abstract: A powered wrench is provided comprising a head formed with an open end, and defining a rotational axis extending through the head. An engaging member is seated in a recess for rotation about the rotational axis, and comprises an outer surface provided with a plurality of gear teeth. A plurality of drive gears transfers input torque from motive structure to the engaging member for driving rotation of the engaging member about the rotational axis. A plurality of auxiliary idler gears is arranged between the plurality of drive gears and the gear teeth of the engaging member such that at least one auxiliary idler gear is always engaged with the gear teeth of the engaging member.

Abstract: A pulling device for removing gears, bearings, sprockets, etc. from the shafts on which they are mounted is disclosed. The pulling device comprises a housing, a laterally movable shaft received within the housing, and a pressure transmitting member interposed between the laterally movable shaft and the housing. The pressure transmitting member is rotatable by means of handles attached to a torque ring mounted on the end thereof. By rotating the pressure transmitting member, the laterally movable shaft, which does not rotate, moves laterally with respect to the pressure transmitting member within the housing of the pulling device. Jaws are attached at substantially equal angular increments to a collar which surrounds the housing and the ends of the jaws engage the underside of the part or component being removed.

Abstract: A relatively lightweight wrench is disclosed herein which is characterized by a gear mounted at its periphery for rotation within a housing, said gear having a major and a minor gear sections removably secured to each other, a collet disposed within the gear for rotation therewith, said collet having an opening of a geometric shape to accommodate a work piece and an open side for admitting a work piece thereinto and a block cooperating with the minor gear section for closing-off the open side of the collet. The wrench is adapted to be opened by removing or opening the minor gear section and removing the collet block to expose a passage leading into the collet opening. In assembling the wrench, a work piece corresponding in shape to the collet opening is passed through the passage into the collet opening, the collet block is positioned in place to close-off the collet opening, and the minor gear section is again secured to the major gear section.
