Abstract:
A pneumatically operated tool driver has a debris suction apparatus including a dust gathering assembly fastened to the front head of tool driver and surrounding the tool, a venturi element mounted on the tool driver, and an air diverting apparatus that uses pressurized air to establish an airflow through the venturi element to create a suction upstream of the venturi element that draws debris from the dust gathering assembly to a dust collection site. The air diverting apparatus obtains the pressurized air from an exhaust diverter that captures pressurized exhaust air expelled through the tool driver's exhaust port, and from a capillary tube coupled to the tool driver's inlet air port.

Claim (Index 1):
Debris suction apparatus for a tool driver that utilizes supplied pressurized air to impart percussive movement to a tool retained in one end of the tool driver, comprising:\n a dust gathering assembly fastened to said one end of said tool driver and surrounding said tool to capture debris produced when said tool impacts a workpiece; a venturi element mounted on said tool driver, said venturi element having an inlet coupled to said dust gathering assembly, an outlet coupled to a dust collection site, a throat portion coupling said inlet to said outlet, and a series of angled air passages in a body of said venturi element that open into said throat portion; and air diverting apparatus that directs pressurized air into to said series of angled air passages of said venturi element to establish an airflow from said inlet to said outlet, thereby creating a suction upstream of the venturi element's inlet that draws said debris captured by said dust gathering assembly through said venturi element and to said dust collection site.
