Patent attributes
Various wrenches, wrench systems, and methods of the present invention include inner and outer mouths that provide increased strength and utility. The inner mouth may be configured with an open or a closed end to receive removable open or closed end gears and perform ratcheting action when the gear seated in the inner mouth and engaged and a rotational force is applied to the gear via the wrench. The outer mouth may prevent the gear from disengaging from the inner mouth when the inner mouth is installed in the outer mouth and provide structural strength to the inner mouth when force is applied to the gear via the wrench. Various embodiments include a handle and a head, where the head includes a fixed jaw and a movable jaw, or belt, forming a mouth configured to receive removable open or closed end gears and perform ratcheting action when a fitting is engaged by the gear positioned in the mouth and rotational force is applied to the fitting via the gear and the wrench. The present invention may include two or more stackable sockets to vary the effective length of the socket.
