Abstract
Abstract A replaceable rotatable therapy head is disclosed wherein the operating mechanism including an impeller and a gear train between the impeller and a ring gear on the housing is supported by a ring which is integral with the emitting nozzle and the supporting ring is held to the body of the structure by means of the flange ring also bonded to the body of the therapy head. The gear train is at the downstream end of the housing and the impeller blades are at the upstream end of the housing spaced from the gear train. A water diversion means is disposed between the gear train and the impeller blades. A friction reducing ring or the like is disposed between the support ring and the housing. The system utilizing the heads, which may be at a selected acute angle, includes aerators in the supply lines for mixing the water with air.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
118 words
A hydrotherapeutic system including in combination: a container for fluid having a size sufficient to permit at least partial submersion of a person therein; a plurality of hydrotherapy heads in said container located beneath the normal fluid level thereof for supplying streams of fluid under pressure at an acute angle to the surface of the container at the location of each of said heads; and rotating means comprising an impeller and gear train mechanism rotated by the fluid flowing through each of said heads for rotating each head independently of the others to thereby automatically, simultaneously and continuously rotate the streams of fluid issuing from said heads to create a varying pattern of fluid movement in said container.
Claim 2
Dependent Claim
118 words
A hydrotherapeutic system including in combination: a container for fluid having a size sufficient to permit at least partial submersion of a person therein; a plurality of hydrotherapy heads in said container located beneath the normal fluid level thereof for supplying streams of fluid under pressure at an acute angle to the surface of the container at the location of each of said heads; and rotating means comprising an impeller and gear train mechanism rotated by the fluid flowing through each of said heads for rotating each head independently of the others to thereby automatically, simultaneously and continuously rotate the streams of fluid issuing from said heads to create a varying pattern of fluid movement in said container.
Claim 3
Dependent Claim
108 words
A hydrotherapeutic system including in combination: a container for fluid having a sufficient size to permit at least partial submersion of a person therein; at least one hydrotherapy head in said container located beneath the normal fluid level thereof for supplying a stream of fluid under pressure at an acute angle to the surface of the container at the location of said at least one hydrotheraphy head; and means located within said head and responsive to said stream of fluid passing through said head for automatically and continuously rotating the stream of fluid issuing from said head to create a varying pattern of fluid movement in said container.
Claim 4
Dependent Claim
108 words
A hydrotherapeutic system including in combination: a container for fluid having a sufficient size to permit at least partial submersion of a person therein; at least one hydrotherapy head in said container located beneath the normal fluid level thereof for supplying a stream of fluid under pressure at an acute angle to the surface of the container at the location of said at least one hydrotheraphy head; and means located within said head and responsive to said stream of fluid passing through said head for automatically and continuously rotating the stream of fluid issuing from said head to create a varying pattern of fluid movement in said container.
Claim 5
Dependent Claim
98 words
A hydrotherapeutic system including in combination: a container for fluid having a size sufficient to permit at least partial submersion of a person therein; a plurality of hydrotherapy heads in said container located beneath the normal fluid level thereof for supplying streams of fluid under pressure at an acute angle to the surface of the container at the location of each of said heads; and means for independently rotating each of said heads for automatically, simultaneously and continuously rotating the streams of fluid issuing from said heads to create a varying pattern of fluid movement in said container.
Claim 6
Dependent Claim
98 words
A hydrotherapeutic system including in combination: a container for fluid having a size sufficient to permit at least partial submersion of a person therein; a plurality of hydrotherapy heads in said container located beneath the normal fluid level thereof for supplying streams of fluid under pressure at an acute angle to the surface of the container at the location of each of said heads; and means for independently rotating each of said heads for automatically, simultaneously and continuously rotating the streams of fluid issuing from said heads to create a varying pattern of fluid movement in said container.
Claim 7
Dependent Claim
33 words
The combination according to claim 3 wherein said rotating means comprises an impeller and gear train mechanism rotated by the fluid flowing through said head for rotating each head independently of the others.
Claim 8
Dependent Claim
48 words
The combination according to claim 4 wherein each of said plurality of hydrotherapy heads supplies a mixture of water and air under pressure, and streams of water and air issue from each of said heads to create said varying pattern of water and air movement in said container.
Claim 9
Dependent Claim
113 words
A hydrotherapeutic system including in combination: a container for fluid having a size sufficient to permit at lease partial submersion of a person therein; a plurality of hydrotherapy heads in said contianer located beneath the normal fluid level thereof for supplying streams of fluid under pressure at an acute angle to the surface of the container at the location of each of said heads, each of said plurality of hydrotherapy heads supplying a mixture of water and air under pressure; and means for automatically simultaneously and continuously rotating the streams of water and air issuing from each of said heads to create a varying pattern of water and air movement in said container.
Claim 10
Dependent Claim
113 words
A hydrotherapeutic system including in combination: a container for fluid having a size sufficient to permit at lease partial submersion of a person therein; a plurality of hydrotherapy heads in said contianer located beneath the normal fluid level thereof for supplying streams of fluid under pressure at an acute angle to the surface of the container at the location of each of said heads, each of said plurality of hydrotherapy heads supplying a mixture of water and air under pressure; and means for automatically simultaneously and continuously rotating the streams of water and air issuing from each of said heads to create a varying pattern of water and air movement in said container.
