A recirculating type cleaner for paint spray guns. The apparatus includes a cabinet supporting a sink and a pair of solvent receptacles each containing a pump and motor for circulating solvent from the receptacles through outlet nozzles and into the sink. In use, the gun is given one or more initial rinses with solvent, from one receptacle, after which a final cleaning rinse is made with new solvent from another receptacle. The sink drain is arranged so that all of the solvent is returned to a single container. Clean solvent passes in use from the clean solvent receptacle to the used or dirty solvent receptacle, leaving fresh solvent uncontaminated, while the contaminated solvent is used repeatedly. The sink includes a fire safety cover secured over the sink opening by a fusible link, and the solvent receptacles are positioned for ready removal to facilitate periodic servicing.

A readily serviceable apparatus for solvent cleaning spray guns or the like, said apparatus comprising, in combination, a cabinet adapted to support a sink unit, a sink unit which includes a bottom wall with a drain opening therein, said sink unit being supported by a portion of said cabinet and further including a fire safety cover with a portion thereof being pivotally affixed to an adjacent margin of said sink unit, and wherein said cabinet includes a rigid cover support unit extending upwardly therefrom, with connecting means including a fusible link extending between a portion of said cover support and a portion of said fire safety cover, whereby said cover will fall to a position covering said sink upon melting of said fusible link, first and second solvent receptacles positioned within said cabinet for ready removal by a service person, with said first solvent receptacle having an inlet opening in an upper portion thereof, a single drain conduit having one of its ends communicating with said drain opening in said sink bottom wall and its other end being arranged so as to communicate in use with the interior of said first receptacle through said inlet opening without impeding the ready removability of said first receptacle, means for withdrawing solvent from said first receptacle and for directing said solvent to the interior of said sink, said first withdrawing and directing means including a first solvent receptacle dip tube, a first pump, a first conduit extending between said first pump and said sink interior, a first discharge nozzle forming the end of said first conduit and being directed to said sink interior, and means adapted to actuate said first pump in response to the command of an operator, means for withdrawing solvent from said second container and for directing said solvent to the interior of said sink, said second withdrawing and directing means including a second solvent receptacle dip tube, a second pump and a second conduit extending between said second pump and said sink interior, a second discharge nozzle forming the end of said second conduit and being directed to said sink interior, and means adapted to actuate said second pump in response to the command of an operator, whereby actuation of said first pump acts to circulate solvent directly from said first receptacle to said sink and back to said first receptacle, whereby actuation of said second pump serves to direct solvent from said second container to said sink interior and then directly to said first solvent receptacle only, whereby all solvent from both receptacles is collected only by said first receptacle, regardless of whether said operator actuates said first or second pumps.
