ABSTRACT:
The specification discloses a fast-acting ratchet wrench (10) which operates in a fast-acting mode of operation and a normal mode of operation. Wrench (10) includes a grip (16) rotatably mounted on one end of a handle (12) with a wrench head (14) disposed on the other end thereof. A rod (74) is attached to the grip (16) and extends through the handle (12) and into the wrench head (14). A drive gear (50) is mounted on the rod (74) within the wrench head (14), and constantly engages teeth (130) on a drive wheel (26). A drive stud (18) is mounted on the wheel (26). A pin (76) is fixedly mounted extending through the rod (74) at a position proximate to the drive gear (50). The wrench (10) is placed in the fast-acting mode of operation by pulling the grip (16) and rod (74) in a direction away from the wrench head (14) to move the pin (76) into slots (66 and 70) or (68 and 72) in the gear (50). To place the wrench (10) in the normal mode of operation, grip (16) is moved towards the wrench head (14) to insert the pin (76) into slots (84 and 88) or (86 and 90) in the wrench head (14).
