Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
164 words
A portable apparatus for cleaning the interior of a vessel comprising: support means fOr resting upon the flange of an opening of a vessel and for attachment to the flange of the vessel; at least a pair of elongated support members supported by said support means for positioning into the interior of the vessel; power means interconnecting (operatively connected to) said support members for extending and retracting one of said elongated support members relative to the other of said elongated support members to (facilitate) collapse said members into a compact unit for removal and insertion of said portable cleaning apparatus into the vessel; spray nozzle means mounted on one said support members for rotation thereon; conduit means on said portable apparatus connected to said spray nozzle for delivering high-pressure cleaning fluid to said spray nozzle means; and motive drive means mounted on said one member and connected to said spray nozzle means for rotating said spray nozzle means through a changing pattern of movement.
Claim 2
Dependent Claim
164 words
A portable apparatus for cleaning the interior of a vessel comprising: support means fOr resting upon the flange of an opening of a vessel and for attachment to the flange of the vessel; at least a pair of elongated support members supported by said support means for positioning into the interior of the vessel; power means interconnecting (operatively connected to) said support members for extending and retracting one of said elongated support members relative to the other of said elongated support members to (facilitate) collapse said members into a compact unit for removal and insertion of said portable cleaning apparatus into the vessel; spray nozzle means mounted on one said support members for rotation thereon; conduit means on said portable apparatus connected to said spray nozzle for delivering high-pressure cleaning fluid to said spray nozzle means; and motive drive means mounted on said one member and connected to said spray nozzle means for rotating said spray nozzle means through a changing pattern of movement.
Claim 3
Dependent Claim
34 words
A portable apparatus for cleaning the interior of a vessel as set forth in claim 1 wherein said spray nozzle means is rotatable about a pair of axes that are perpendicular to each other.
Claim 4
Dependent Claim
71 words
A portable apparatus for cleaning the interior of a vessel as set forth in claim 1 wherein said spray nozzle means and said motive drive means include spray nozzles mounted on a first bevel gear rotatable about a first axis and driven by a second bevel gear rotatable about a second axis; and wherein said second bevel gear has a plurality of teeth differing in number than said first bevel gear.
Claim 5
Dependent Claim
36 words
A portable apparatus for cleaning the interior of a vessel as set forth in claim 3 including pump means operatively attached to said conduit means for supplying fluid thereto at pressures of greater than 3000 p.s.i.
Claim 6
Dependent Claim
69 words
A portable apparatus for cleaning the interior of a vessel as set forth in claim 4 wherein said other support member comprises a pair of longitudinally extending hollow tubes that are interconnected by a universal joint to facilitate the placement of said portable apparatus into said vessel and each of said hollow tubes includes a bracket that cooperates with a locking bar to maintain said tubes in fixed relationship.
Claim 7
Dependent Claim
53 words
A portable apparatus for cleaning the interior of a vessel as set forth in claim 1 wherein said power means includes a hydraulic cylinder means mounted on one of said pairs of support members and is operative to extend and retract said one support member relative to the other of said support members.
Claim 8
Dependent Claim
38 words
A portable apparatus for cleaning the interior of a vessel as set forth in claim 1 wherein pump means is operatively connected to said conduit means for supplying fluid thereto at pressures between 3000 p.s.i. and 6000 p.s.i.
Claim 9
Dependent Claim
152 words
A portable apparatus for cleaning the interior of a vessel comprising: support means for attachment to the vessel; a first support member mounted on said support means; a second support member pivotally connected to said first support member; a third hollow support member pivotally connected by crossmembers to said second support member; power means operatively connected to said support members for extending and retracting said third support members relative to said second support members to facilitate the removal and insertion of said portable cleaning apparatus into the vessel; locking means securing said first and second support members together; spray nozzle means mounted on said third support members for rotation thereon; conduit means on said portable apparatus connected to said spray nozzle for delivering high-pressure cleaning fluid to said spray nozzle means; and motive drive means connected to said spray nozzle means about a pair of axes that are perpendicular to each other.
Claim 10
Dependent Claim
152 words
A portable apparatus for cleaning the interior of a vessel comprising: support means for attachment to the vessel; a first support member mounted on said support means; a second support member pivotally connected to said first support member; a third hollow support member pivotally connected by crossmembers to said second support member; power means operatively connected to said support members for extending and retracting said third support members relative to said second support members to facilitate the removal and insertion of said portable cleaning apparatus into the vessel; locking means securing said first and second support members together; spray nozzle means mounted on said third support members for rotation thereon; conduit means on said portable apparatus connected to said spray nozzle for delivering high-pressure cleaning fluid to said spray nozzle means; and motive drive means connected to said spray nozzle means about a pair of axes that are perpendicular to each other.
Claim 11
Dependent Claim
120 words
A portable cleaning apparatus for cleaning the interior of a vessel as set forth in claim 8 wherein said spray nozzle means includes a pair of spaced nozzle assemblies mounted on said third support member; each of said nozzle assemblies having a first bevel gear journaled fOr rotation thereon and a second bevel gear meshing with said first bevel gear; a pair of spray nozzles mounted on said second bevel gear; rotary union means interconnecting said spray nozzles with said conduit means for delivery of high-pressure cleaning fluid to said spray nozzle means; said second bevel gear having a less number of teeth than said first bevel gear; and said motive drive means being connected to said first bevel gear.
