ABSTRACT:
A novel device is disclosed for driving nail-like fasteners with associated washers into a workpiece. The device comprises a pneumatic driver apparatus, preferably one substantially the same as the tool disclosed in U.S. Pat. No. 4,040,554, in association with a washer dispenser apparatus capable of semiautomatically deploying washers from a washer magazine so that the washers are fixed to the workpiece by the heads of the fasteners. The pneumatic driver and washer dispenser are attached together as a discrete assembly which is mounted on a hanger assembly so as to appear substantially weightless to a tool operator, and the driver and dispenser are adapted to be activated by a remotely positioned trigger device.
