Abstract
Abstract A hydrotherapeutic unit to be permanently installed with a bathtub or tank. The unit includes a manifold mounted on the end wall of the tub and the manifold defines a water supply chamber and a return chamber. A pair of conduits extend through the end wall of the tub on opposite sides of the waste valve operating mechanism and one conduit establishes communication between the supply chamber and the discharge side of a pump located outside of the tub, while the second conduit establishes communication between the return chamber and the suction side of the pump. A nozzle assembly is located within the tub and is connected to the supply chamber so that water discharged by the pump is delivered to the supply chamber and then ejected under high pressure from the nozzle assembly within the body of water in the tub. The water is recirculated from the tub through the return chamber to the pump.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
258 words
A hydrotherapeutic unit, comprising a tub to contain water and having a drain opening in the bottom surface thereof and having a waste valve control opening in the end wall of the tub in alignment with the longitudinal centerline of the tub, a drainline connected to the drain opening, waste valve means located in the drainline for opening and closing the drainline, control means connected to the waste valve means and disposed in alignment with the longitudinal centerline of the tub, said control means including an operating member extending within said waste valve control opening, a manifold mounted on the inner surface of the end wall of the tub and defining a supply chamber and a return chamber, a nozzle assembly disposed within the tub and connected to the supply chamber whereby water from the supply chamber is delivered to the nozzle assembly and is ejected from the nozzle assembly within the tub, first conduit means providing communication between the tub and the return chamber, pumping means located on the exterior of the tub, second conduit means extending through the end wall of the tub and providing communication between the supply chamber and the discharge side of said pumping means, and third conduit means extending through an opening in the end wall of the tub and providing communication between the return chamber and the suction side of the pumping means, said second and third conduit means being offset from a vertical plane passing through the longitudinal centerline of the tub and being located laterally of said control means.
Claim 2
Dependent Claim
258 words
A hydrotherapeutic unit, comprising a tub to contain water and having a drain opening in the bottom surface thereof and having a waste valve control opening in the end wall of the tub in alignment with the longitudinal centerline of the tub, a drainline connected to the drain opening, waste valve means located in the drainline for opening and closing the drainline, control means connected to the waste valve means and disposed in alignment with the longitudinal centerline of the tub, said control means including an operating member extending within said waste valve control opening, a manifold mounted on the inner surface of the end wall of the tub and defining a supply chamber and a return chamber, a nozzle assembly disposed within the tub and connected to the supply chamber whereby water from the supply chamber is delivered to the nozzle assembly and is ejected from the nozzle assembly within the tub, first conduit means providing communication between the tub and the return chamber, pumping means located on the exterior of the tub, second conduit means extending through the end wall of the tub and providing communication between the supply chamber and the discharge side of said pumping means, and third conduit means extending through an opening in the end wall of the tub and providing communication between the return chamber and the suction side of the pumping means, said second and third conduit means being offset from a vertical plane passing through the longitudinal centerline of the tub and being located laterally of said control means.
Claim 3
Dependent Claim
20 words
The unit of claim 1, wherein said second and third conduit means are located on opposite sides of said plane.
Claim 4
Dependent Claim
37 words
The unit of claim 1, wherein said chambers are located at different vertical levels, and said unit includes air vent means connected to the upper portion of the chamber which is located at the highest vertical level.
Claim 5
Dependent Claim
37 words
The unit of claim 1, wherein said supply chamber is located at a level above said return chamber and said unit includes air vent means connected to the supply chamber for selectively releasing air from said chamber.
Claim 6
Dependent Claim
58 words
The unit of claim 4, wherein said air vent means comprises fourth conduit means providing communication between said supply chamber and the atmosphere, valve means for opening and closing said fourth conduit means, and an operating member located on the exterior of the manifold and operably connected to said valve means for opening and closing said valve means.
Claim 7
Dependent Claim
48 words
The unit of claim 4, wherein the upper portion of the supply chamber extends to a level above the pump and above said second and third conduit means, said air vent means being located in said upper portion of the supply chamber above the level of said pump.
Claim 8
Dependent Claim
42 words
The unit of claim 1, wherein said manifold includes a hollow casing and is provided with a generally horizontal wall which extends across the interior of the casing and divides the casing into an upper supply chamber and a lower return chamber.
Claim 9
Dependent Claim
39 words
The unit of claim 1, wherein said supply chamber is located above the level of the return chamber and both the supply chamber and the return chamber extend laterally in both directions from the longitudinal centerline of the tub.
Claim 10
Dependent Claim
33 words
The unit of claim 1, wherein said supply chamber is located at a level above said return chamber and said first conduit means is located at the lower end of said return chamber.
