Abstract: A wrench having a floating pawl in a non-circular opening in the head of the wrench. The pawl has alternate positions for forward and reverse movement of the wrench. A reversing lever selectively moves an actuator to alternately engage one or the other leg of a spring within the wrench. Movement of the selected leg resiliently engages the pawl to move the pawl into the forward or reverse position. The pawl translates and rocks within the pawl opening when the wrench is ratcheted to minimize back swing arc.

Abstract: A one or two sided or headed ratcheting driving wrench. Each side or head has a rotatable tool carrier constrained to rotate in only one direction by interengaging teeth formed in the tool carrier and in its housing. Both sets of teeth may be pointed or rounded. In one direction, torque locks the tool carrier to the housing, and thus drives a tool such as a screw driver blade or a socket. In the other direction, torque causes the tool carrier to disengage from the housing. Thus, intermittent one way rotation is assured. The chamber is slightly elongated, having two rows of teeth, each row separated from the other by stretches of chamber wall lacking teeth. Should the tool carrier back out of contact with one row of teeth, it will shortly engage the second row of teeth, thereby maintaining driven relationship with the working head. The wrench has a bent lever or handle to allow for working in tight quarters. The tool carrier has a square hole formed therein, for receiving a driven tool.

Abstract: A tool display pack includes a board and a security device. The board has an engaging hole with a shoulder section. The security device includes an end pivotally connected to the boar. A resilient locking member projects from an inner side of the security device that faces a front side of the board. The resilient locking member includes a hook formed on a distal end thereof and a protrusion formed adjacent to the hook. The security device includes a through-hole through which a tool to be displayed is extended. The locking member is extendible through the engaging hole of the boar such that the protrusion and the hook of the resilient locking member are located on a rear side of the board. The protrusion is releasably engaged, with the shoulder section of the board, and the hook prevents pivotal movement of the security device relative to the board when the hook is moved to bear against the shoulder section of the board, thereby locking the tool in place.
