Claims
- 1. A readily serviceable apparatus for solvent cleaning spray guns, 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, 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 direct 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.
- 2. An apparatus as defined in claim 1 wherein said cabinet includes a transversely extending interior shelf for positioning said receptacle for ready removal.
- 3. An apparatus as defined in claim 1, wherein said cabinet includes at least one door which, when open, provides ready service access to said solvent receptacles, and when closed, prevents access to said receptacles.
- 4. An apparatus as defined in claim 1 wherein said second solvent receptacle dip tube has its lower end spaced substantially apart from the lower wall of said second solvent receptacle to limit the amount of solvent able to be withdrawn from said second container.
- 5. An apparatus as defined in claim 1, said apparatus further including a cover unit hingedly mounted to said cabinet or said sink for pivotal movement between open and closed positions, with said first and second conduits being flexible conduits having portions thereof secured to said cover unit, whereby movement of said cover unit will not damage said conduits.
- 6. An apparatus as defined in claim 1, wherein said actuating means for said first and second pumps comprise, respectively, first and second, pedal-operated pump controls.
- 7. An apparatus as defined in claim 6, wherein each of said pump controls is adapted for incrementally varying the rate at which said pumps operate, whereby said flow rates of solvent circulation may be controlled.
- 8. An apparatus as defined in claim 1, wherein said first and second pump comprise air operated pumps.
- 9. An apparatus as defined in claim 8, said apparatus further including means for directing compressed air from a source of compressed air to each of said pumps.
