Abstract
Abstract A fluid jet device for removing foreign matter from a pool of liquid comprising a hollow substantially cylindrical housing including a housing channel formed therein, an elongated rotatably member including a convoluted spiral formed on the outer surface thereof disposed within the housing channel and a coupling device to rotatably mount the elongated rotatably member to permit fluid to pass rapidly through the convoluted spiral to cause a rotation of the elongated member continuously changing the direction of the fluid exiting the fluid jet device.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
120 words
A fluid jet device comprising an outer housing having a centrally disposed housing channel formed therein and an elongated rotatable member operatively disposed within said housing channel in combination with a coupling means to rotatably support said elongated rotatable member, said coupling means comprises a rotating means including a first and second member, said first member being attached to a stationary element and said second member being fixedly attached to said elongated rotatable member, said rotatable member comprises an elongated substantially cylindrical member having at least one convoluted spiral formed the entire length thereof to cooperatively form a fluid channel with the periphery of said housing channel, whereby fluid forced through said convoluted spiral continuously rotates said elongated rotatable member.
Claim 2
Dependent Claim
120 words
A fluid jet device comprising an outer housing having a centrally disposed housing channel formed therein and an elongated rotatable member operatively disposed within said housing channel in combination with a coupling means to rotatably support said elongated rotatable member, said coupling means comprises a rotating means including a first and second member, said first member being attached to a stationary element and said second member being fixedly attached to said elongated rotatable member, said rotatable member comprises an elongated substantially cylindrical member having at least one convoluted spiral formed the entire length thereof to cooperatively form a fluid channel with the periphery of said housing channel, whereby fluid forced through said convoluted spiral continuously rotates said elongated rotatable member.
Claim 3
Dependent Claim
44 words
The fluid jet device of claim 1 wherein said coupling means further includes a mounting means comprising a mounting flange having mounting housing pivotally disposed therein, said coupling means operatively coupled to said mounting means to permit manual pivoting of said fluid jet device.
Claim 4
Dependent Claim
63 words
The fluid jet device of claim 1 wherein said outer housing and said elongated member are affixed relative to one another, said outer housing further including a discharge orifice formed on the outer portion thereof, the axis of said discharge orifice being offset relative to the longitudinal axis of said outer housing to generate a rotating force to rotate said fluid jet device.
