Abstract
Abstract An apparatus for cleaning vehicle parts includes a reservoir containing a lower layer of water and an upper layer of solvent, a fluid pump for conveying solvent from the solvent layer to the parts to remove dirt and grease therefrom, a solvent collector for feeding the used solvent to a plurality of sequentially arranged settling tanks and a filter for receiving the solvent from the settling tanks and removing suspended particles therefrom. The solvent passes through the filter and the filtered solvent is discharged into the water layer of the reservoir. The lighter-than-water solvent rises to the solvent layer, leaving particulate matter behind in the water layer.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
178 words
A washer for vehicle parts, comprising: a tank containing a layer of water and a layer of lighter-than-water solvent; a fluid pump having an inlet port positioned in said solvent layer for receiving solvent therefrom and an outlet port conveying solvent through a solvent supply conduit to a utilization point; collection means beneath the utilization point for conveying solvent discharged from said solvent supply conduit after said solvent has washed the parts; a plurality of inclined, sequentially arranged settling tanks receiving the solvent from said collection means; a filter positioned adjacent the lower settling tank and receiving the solvent flowing therefrom, said filter tank containing a filter material, a discharge port beneath said filter material and a tube connected to said discharge port opening into said water layer; and a filter barrier dividing said tank into two compartments, a first compartment receiving the contents of said filter tank and a second compartment communicating with said fluid pump inlet port whereby recirculated solvent sequentially flows through said filter barrier, pump, collection means, settling tanks, filter tank and water layer.
Claim 2
Dependent Claim
178 words
A washer for vehicle parts, comprising: a tank containing a layer of water and a layer of lighter-than-water solvent; a fluid pump having an inlet port positioned in said solvent layer for receiving solvent therefrom and an outlet port conveying solvent through a solvent supply conduit to a utilization point; collection means beneath the utilization point for conveying solvent discharged from said solvent supply conduit after said solvent has washed the parts; a plurality of inclined, sequentially arranged settling tanks receiving the solvent from said collection means; a filter positioned adjacent the lower settling tank and receiving the solvent flowing therefrom, said filter tank containing a filter material, a discharge port beneath said filter material and a tube connected to said discharge port opening into said water layer; and a filter barrier dividing said tank into two compartments, a first compartment receiving the contents of said filter tank and a second compartment communicating with said fluid pump inlet port whereby recirculated solvent sequentially flows through said filter barrier, pump, collection means, settling tanks, filter tank and water layer.
Claim 3
Dependent Claim
36 words
The apparatus of claim 1 wherein a settling tray is placed in said first compartment for receiving the discharge from said filter tank whereby particulate matter discharged from said tank is collected in said settling tray.
Claim 4
Dependent Claim
49 words
The apparatus of claim 1 wherein said filter barrier comprises an elongated, U-shaped screen extending from one tank wall to an adjoining tank wall and removable therefrom, said screen having its open side positioned downwardly against the bottom of the tank and its interior filled with a filtering material.
Claim 5
Dependent Claim
93 words
The apparatus of claim 1 further comprising: a basket having a porous bottom and a handle; an agitating tank positioned in said solvent tank for receiving said basket with said porous bottom in said solvent layer, said agitating tank having an opening through the bottom of the tank sidewall beneath said water layer; support means for positioning said basket in said agitating tank with the porous bottom in said solvent; and reciprocating actuator means secured to said support means for repeatedly moving the parts in said basket up and down in said solvent.
