Control valve for a mandrel collection system

Claim 1

A power operated blind rivet tool adapted to automatically pull the mandrel of a blind rivet to upset the rivet body in a workpiece comprising: a. an upper housing containing a rivet setting mechanism; b. a lower housing secured to said upper housing and having a pressure vessel with a piston operably connected to said rivet setting mechanism; c. said lower housing having a downwardly extending circumferential flange having a planar surface adapted to rest on a worksurface to permit the tool to be positioned upright on the worksurface; d. a primary air supply line passing through said flange and a central support means, with said primary air supply line being operably connected through a valve to supply air to said piston, said central support means extending to said planar surface of said flange to provide additional support area for supporting the tool upright on a worksurface; e. a mandrel collection system on said rivet setting mechanism to retrieve the pulled mandrels; f. a secondary air line connected to said primary air line within the confines of said flange and passing to said mandrel collection system to operate said mandrel collection system; g. said secondary air line being positioned within the physical confines of the tool; and h. a control valve positioned between said flange and said central support means and located within said planar surface and being operably connected in said secondary air line, i. said control valve being accessible from the underside of said pressure vessel to control air supplied to said mandrel collection system.
