Abstract: A torque-multiplying hand wrench incorporating the features of a standard ratchet wrench along with a lever action torque multiplying feature. A torque multiplying lever arm is attached to a cam element, the eccentric of which acts upon yoke-shaped actuator when the lever arm is rotated. The actuator interacts with a standard ratchet device to apply torque to a threaded fastener. The handle of the wrench acts either as a standard ratchet wrench handle or as a reaction arm in conjunction with use of the torque multiplying lever arm.
