Abstract
Abstract Apparatus for the cleaning of mechanical or structural parts by circulation of cleaning solution within a tank having cavitated end walls which house circulating propellers and wherein sludge is entrapped in one or a pair of relatively small volume containers receiving side streams of propeller-displaced cleaning solution, these containers being manually removable from the tank without interruption of the parts cleaning operation. The invention also provides improvements in the tank and propeller housing constructions and benefits resulting from association within the tank of the propeller housing with vertical end walls of the tank.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
85 words
Parts cleaning equipment comprising a relatively large volume cleaning liquid tank for reception of soiled parts, a propeller in the tank and operable to displace the liquid against parts submerged in the liquid, a relatively small volume sludge trap container positioned near the propeller to receive a side stream of tank liquid being displaced thereby and forming a sludge settling chamber from which the side stream returns to the tank liquid, said trap container being separable from the tank for removal of its sludge accumulation.
Claim 2
Dependent Claim
85 words
Parts cleaning equipment comprising a relatively large volume cleaning liquid tank for reception of soiled parts, a propeller in the tank and operable to displace the liquid against parts submerged in the liquid, a relatively small volume sludge trap container positioned near the propeller to receive a side stream of tank liquid being displaced thereby and forming a sludge settling chamber from which the side stream returns to the tank liquid, said trap container being separable from the tank for removal of its sludge accumulation.
Claim 3
Dependent Claim
26 words
Cleaning equipment according to claim 1, in which said chamber is partially submerged in the tank liquid and is removable through the top of the tank.
Claim 4
Dependent Claim
29 words
Cleaning equipment according to claim 1, including a duct through which said side stream is elevated by the propeller above the tank liquid level for delivery into said container.
Claim 5
Dependent Claim
41 words
Cleaning equipment according to claim 1, in which said propeller is contained within a recessed housing projecting into the tank from an end wall thereof and said container receives said side stream through a passage in the wall of said housing.
Claim 6
Dependent Claim
16 words
Cleaning equipment according to claim 4, in which said container is removably supported on said housing.
Claim 7
Dependent Claim
20 words
Cleaning equipment according to claim 5, in which said container includes sludge settling chambers above opposite sides of said housing.
Claim 8
Dependent Claim
24 words
Cleaning equipment according to claim 6, in which said side stream is delivered to the container through a duct extending upwardly between said chambers.
Claim 9
Dependent Claim
18 words
Cleaning equipment according to claim 7, including valve means for variably controlling side stream flow through said duct.
Claim 10
Dependent Claim
25 words
Cleaning equipment according to claim 7, including means for selectively controlling delivery through said duct of separate portions of the side stream to said chambers.
Claim 11
Dependent Claim
23 words
Cleaning equipment according to claim 4, in which said housing is of truncated pyramidal shape having a top side which supports said container.
Claim 12
Dependent Claim
21 words
Cleaning equipment according to claim 10, in which the container bottom has angular conformity with said top side of the housing.
Claim 13
Dependent Claim
39 words
Cleaning equipment according to claim 11, including a duct extending upwardly through said top side and through which said side stream is elevated by the propeller to flow into chambers in the container at opposite sides of said duct.
Claim 14
Dependent Claim
19 words
Cleaning equipment according to claim 12, including also means for variably controlling the side stream flow through said duct.
Claim 15
Dependent Claim
21 words
Cleaning equipment according to claim 12, including also tank liquid heating means in a corner of the tank beyond said housing.
