Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
128 words
In tank-washing apparatus having a turret rotatable about a first axis, at least one nozzle carried by the turret and swingable about a second axis at an angle to the first, and a turbine driven by the wash water and coupled to drive the turret and nozzle, the improvement comprising: a first part of said apparatus constructed for sealed mounting in the wall of a tank, said first part holding said turret in a position to be located within the tank and said turbine in a position outside the tank, a second part of said apparatus removably attachable to said first part outside the tank, and transmission gear mounted in said second part for cooperation with said first part to transmit drive from the turbine to the nozzle.
Claim 2
Dependent Claim
128 words
In tank-washing apparatus having a turret rotatable about a first axis, at least one nozzle carried by the turret and swingable about a second axis at an angle to the first, and a turbine driven by the wash water and coupled to drive the turret and nozzle, the improvement comprising: a first part of said apparatus constructed for sealed mounting in the wall of a tank, said first part holding said turret in a position to be located within the tank and said turbine in a position outside the tank, a second part of said apparatus removably attachable to said first part outside the tank, and transmission gear mounted in said second part for cooperation with said first part to transmit drive from the turbine to the nozzle.
Claim 3
Dependent Claim
43 words
Apparatus as claimed in claim 1 including a reciprocating rod mounted in said first part and coupled to said nozzle to effect swinging movement thereof, said transmission gear comprising means for converting rotary motion of said turbine into reciprocating motion of said rod.
Claim 4
Dependent Claim
57 words
Apparatus as claimed in claim 2 in which said converting means comprise a threaded member, a captive nut member cooperating with said threaded member to effect longitudinal movement thereof, a reversing clutch coupling said captive nut member to said turbine and means for reversing said reversing clutch at the limits of longitudinal movement of the threaded member.
Claim 5
Dependent Claim
34 words
Apparatus as claimed in claim 2 comprising a rack on said reciprocating rod and a toothed gear member coupled to said nozzle and engaging the rack for the transmission of drive to the nozzle.
Claim 6
Dependent Claim
37 words
Apparatus as claimed in claim 2, comprising a tube surrounding the reciprocating rod, said turret being attached to said tube at one end thereof and the other end thereof being coupled to the turbine for rotation thereby.
Claim 7
Dependent Claim
22 words
Apparatus as claimed in claim 1 wherein said second part comprises further transmission Gear for rotation of the turret by the turbine.
Claim 8
Dependent Claim
56 words
Apparatus as claimed in claim 1 wherein said first part comprises a fixed casing, said turret being rotatably mounted on the inner end of said casing, a passage within said casing for the flow of wash water from the turbine to the nozzle, and drive means for said turret and said nozzle passing through said casing.
Claim 9
Dependent Claim
30 words
Apparatus as claimed in claim 7 including hydrostatic pad bearing means rotatably supporting said turret on said casing and means for feeding wash water under pressure to said bearing means.
Claim 10
Dependent Claim
70 words
Apparatus as claimed in claim 7 wherein said drive means comprise a tube extending through said passage, the turret being attached to the inner end of the tube, and a reciprocating rod within said tube, said rod carrying a rack and said nozzle having a toothed gear element engaging said rack, and wherein said transmission gear comprises a reversible clutch and screw means coupling said turbine to said reciprocating rod.
