Abstract: In a pliers-type tool having a stationary first handle and a second handle pivotally movable relative to the first handle, a slidable jaw carrier is movable along a rectilinear guiding track in a body member due to the pivotal movement of the second handle. The first handle is fixed to the body member. The second handle is in engagement with a toggle mechanism including a driver arm which, in turn, is pivotally attached at a stationary location to the body member. When the second handle is pivoted, the driver arm contacts, in a gliding manner, the jaw carrier and moves it rectilinearly in the guiding track. The driver arm extends transversely of the rectilinear guiding direction of the guiding track. Forces acting through the driver arm in the direction transversely of the rectilinear direction of the guiding track are prevented from affecting the movement of the jaw carrier. The second handle can be connected to the first handle by a connecting link.

Abstract: A thumb adjustable, parallel jaw end wrench, that uses a worm gear and a movable jaw with a rack, is provided with a locking feature. The worm gear is so mounted in the fixed jaw portion of the wrench that it has play in its axial direction. A first hole ("cam follower hole") that extends perpendicularly away from the head end of the gear is intersected by a second hole ("cam pin hole") running perpendicular to the cam follower hole. Biasing means urge the worm gear toward the cam pin hole. A cylindrical pin having a cam surface with high and low positions that extends radially around a central segment of the pin is rotatably mounted in the cam pin hole. Cam follower means slidably mounted in the cam follower hole ride on the cam surface and extend to the head end of the worm gear. To lock the wrench's grip on an object, the pin is turned to its high cam position, causing the follower means to push the gear, and therefore the rack and movable jaw as well, toward the fixed jaw.
