Abstract: A novel system for visually coding tools as to their size comprises a maximum of two sets of differently colored bands which are placed on the surface of the tool. Each band of each color represents a portion of the size of the tool. Thus, when the number of bands of each color is counted, the size of the tool is indicated. Different colors are used to indicate metric tools versus English tools. Different color schemes may be used to represent the ownership of the tools.

Abstract: An electrical T-fastener pliers has jaws (1, 3) with grip bays (8, 9, 39, 40) that are positioned on T-joint fastener jaws (15, 16, 17, 18) to be clamped onto targeted wires (19) by hand-squeezing handles (2, 4) of the electrical pliers. Jaws of the T-joint fasteners (12) are pressured against jaws of the pliers by outward pressure of outwardly sprung T-joint fasteners against designedly opened pliers jaws or optionally by inward pressure of the pliers jaws against jaws of unsprung T-joint fasteners (13). This provides a spring-pressured containment of a T-joint fastener while the pliers are being positioned in T-joining relationship to targeted electrical wiring. The handles can be extended at angles from the jaws to position a bottom handle designedly removed from a working surface in order to provide finger space between a working surface and in order to facilitate positioning the jaws under wires in close proximity to surfaces.

Abstract: A ratchet wrench comprises an output drive member (13,17) rotatable about a first axis, a drive housing (15) containing the output drive member, and a handle (14) on the drive housing for rotating the drive housing about the first axis. A rotary member (24) within the handle is rotatable about a second axis and a drive ring (21) extends around the output drive member. A coupling means (25) couples the rotary member to the drive ring so that rotation of the rotary member about the second axis causes rotation of the drive ring about the output drive member. The wrench also includes primary ratchet means (17, 42) for selectively unidirectionally coupling the output drive member to the housing, and secondary ratchet means (23, 43) for selectively unidirectionally coupling the output drive member to the rotary member through the drive ring whereby the output drive member (13, 37) can be rotated in a selected direction either by rotation of the handle 14 or by rotation of the rotary member (24).

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.
