Combination parts jet washer and sink washer with parts washer with minimum grip sprocket drive system

A portable multi-function parts washer for removing contaminants from parts either by hand or automatically using an aqueous cleaning fluid, the parts washer comprising:

• a base cabinet having sides and an open top defining a compartment having an upper jet cleaning section and a lower section;
• a rotating cleaning basket mounted in the jet cleaning section for receiving parts to be washed by jet cleaning, attached to a vertical drive shaft, the vertical drive shaft being driven by at least one minimum grip drive sprocket coupled to the vertical drive shaft;
• a spray manifold in the jet cleaning section having at least one spray nozzle oriented to direct a cleaning spray toward the rotating cleaning basket;
• a fluid pump having an outlet and an inlet;
• a sink mounted on the cabinet open top overlying the jet cleaning section having a closed position closing the cabinet open top and an open position providing access to the jet cleaning section to load and remove parts therefrom;
• a hand washer for manually cleaning parts in the sink;
• a drain in the sink;
• a fluid reservoir in the lower section receiving the fluid discharged from the sink through the drain, and receiving the fluid discharged from the jet cleaning section;
• and
• the fluid pump inlet in fluid communication with the reservoir and having the fluid pump outlet in fluid communication with the manifold and the sink washer to supply pressurized cleaning fluid to the hand washer and the spray manifold exclusively from the reservoir independent of any external fluid supply.

A portable multi-function parts washer for removing contaminants from parts either by hand or automatically using an aqueous cleaning fluid, the parts washer comprising:

• a base cabinet having sides and an open top defining a compartment having an upper jet cleaning section and a lower section;
