Abstract

A pneumatically operated hand-held wire stripping tool having a first housing for supporting operating elements of the tool and a second housing for substantially containing pneumatic elements of the tool is constructed such that the first housing is rotatably coupled to the second housing for rotation into either a left hand or right hand operating position. The operating elements of the tool include a first pair of opposed clamping jaws and a second pair of opposed cutting blades. The jaws and blades are coupled such that initial actuation of the tool closes the jaws and blades and continued actuation displaces the jaws with respect to the blades. The pneumatic elements comprise a pneumatic valve and a diaphragm supported on a stem with the stem extending through the diaphragm and into engagement with one of the operating elements of the tool. An aperture extends coaxially with and substantially through the stem and terminates adjacent the operating element. A viaduct extends from the valve and into the aperture for providing air communication between the valve and aperture. An opening in the stem passes through the aperture for communicating air to one side of the diaphragm.
