ABSTRACT:
A sheet metal working tool particularly adapted for vehicle body repair comprising a slide hammer assembly attached to a suction cup from which air is drawn through the assembly. The tool incorporates a compressed air-operated vacuum ejector functioning on the venturi principle into a stop on the end of the slide hammer assembly opposite the suction cup. The exhaust stream is effectively muffled and diffused through a collar of hard, rugged, porous material that fits within a channel in the surface of the vacuum ejector/stop and that completely covers the port through which the exhaust exists the vacuum ejector/stop. The suction cup is reinforced by an internally located stiffener, and shock loads that may damage the threaded connections among components of the tool are damped by a shock absorbing hose connected to the vacuum ejector/stop.
