Universal suction attachment for pneumatic power tools

Abstract

A universal suction attachment for pneumatic power tools includes a housing having a tool coupling portion, a duct portion, and a focused outflow portion. The tool coupling portion is capable of connection to an exhaust port of the pneumatic power tool such that exhaust air from the tool is captured therewithin. The focused outflow portion is capable of connection to a vacuum conduit and to a collection tube. A duct is provided throughout the duct portion, providing flow between the tool coupling portion and the focused outflow portion. In use, exhaust air from the power tool that is captured within the tool coupling portion is ducted through the duct portion and into the focused outflow portion. A resulting flow of the exhaust air creates a vacuum in the vacuum conduit to transport debris to the collection tube.

What is claimed is:  
     
         1 . A universal suction attachment for pneumatic power tools, comprising: 
 a housing, said housing including (i) a tool coupling portion capable of connection to an exhaust port of the pneumatic power tool such that exhaust air from the tool is captured therewithin, (ii) a duct portion, and (iii) a focused outflow portion, said focused outflow portion being capable of connection to a vacuum conduit and to a collection tube; and    a duct provided throughout said duct portion, said duct providing flow between said tool coupling portion and said focused outflow portion,    wherein in use, exhaust air from the power tool captured within said tool coupling portion is ducted through said duct and into said focused outflow portion, such that a resulting flow of exhaust air creates a vacuum in the vacuum conduit to transport debris resulting from operation of the tool, to the collection tube.    
     
     
         2 . The universal suction attachment for pneumatic power tools of  claim 1 , wherein said tool coupling portion further includes a telescoping seal cap and a seal spring provided there within, such that a substantially airtight connection may be provided between said housing and various pneumatic power tools.
