Abstract
Abstract A cleaning apparatus for filters of the cylindrical type used with carburetors of internal combustion engines comprising a tank for receiving cleaning fluid and a plurality of spray means for discharging cleaning fluid therein extending axially into the tank, a turntable adapted to support the filters rotatable about an axis concentric with one of the spray means and the turntable having axially extending means terminating adjacent the upper end of the tank, a cover adapted to close the upper end of the tank with a drive motor mounted thereon and a drive shaft extending into the upper end of the tank with means associated therewith for engaging the axially extending means of the turntable to effect rotation of the turntable.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
156 words
A cleaning apparatus for filters which comprises: a tank for receiving cleaning liquid and provided with transversely spaced cleaning liquid spray means with said cleaning liquid spray means extending axially within said tank, a rotatable support means for said filters disposed concentrically with one of said spray means having secured thereto spaced arm members extending longitudinally upwardly within said tank and terminated adjacent the upper end of said tank, a cover member adapted to close the upper end of said tank, drive means supported by said cover member which extend into the interior of said tank for engaging said spaced arm members and rotating said support means, means associated with said support means for exerting an axial compression force on said filters and restraining said filters against axial movement relative to said support means, and means associated with said tank for continuously supplying cleaning liquid to said spray means and withdrawing cleaning liquid from said tank.
Claim 2
Dependent Claim
156 words
A cleaning apparatus for filters which comprises: a tank for receiving cleaning liquid and provided with transversely spaced cleaning liquid spray means with said cleaning liquid spray means extending axially within said tank, a rotatable support means for said filters disposed concentrically with one of said spray means having secured thereto spaced arm members extending longitudinally upwardly within said tank and terminated adjacent the upper end of said tank, a cover member adapted to close the upper end of said tank, drive means supported by said cover member which extend into the interior of said tank for engaging said spaced arm members and rotating said support means, means associated with said support means for exerting an axial compression force on said filters and restraining said filters against axial movement relative to said support means, and means associated with said tank for continuously supplying cleaning liquid to said spray means and withdrawing cleaning liquid from said tank.
Claim 3
Dependent Claim
75 words
A cleaning apparatus as in claim 1, wherein said rotatable support means comprises a turntable for supporting said filters concentrically with said liquid spray means within said tank, and said means associated with said turntable for restraining axial movement of said filter comprising at least one tie rod member extending longitudinally upwardly from said turntable and having a compression bar associated therewith for exerting a clamping engagement with a said filter mounted on said turntable.
Claim 4
Dependent Claim
50 words
A cleaning apparatus as in claim 2, wherein said turntable has two diametrically oppositely disposed tie rod members which extend upwardly therefrom within said tank with each of said members having a said compression bar associated therewith for exerting a clamping engagement on a said filter supported on said turntable.
Claim 5
Dependent Claim
23 words
A cleaning apparatus as in claim 2, wherein said compression bar has a quick detachable connector means engageable with said tie rod member.
Claim 6
Dependent Claim
84 words
A cleaning apparatus as in claim 4, wherein said quick detAchable connector means associated with said compression bar has a transverse passage therethrough adapted to freely receive said tie rod member, a lever arm pivotally supported on a surface of said compression bar at a point spaced from said passage, said arm having the forward end thereof adapted to form a secure engagement with said tie rod member, and said forward end of said arm normally urged into engagement with said tie rod member.
