Abstract
Abstract The innovation disclosed lends itself to bathroom use, more particularly, on the usual shower head wall. It is characterized by a partitioned manifold mounted in place of the customary shower head and is connected to the hot and cold water supply pipe by a vacuum breaker mechanism for blocking siphoning back of water into the plumbing system. The bottom of the manifold suspends a battery of individual containers for cleansing lotions, shampoos, rinses, oils and the like, each having a finger-tip control knob controlling a coordinated metering valve. These valves are selectively usable. When closed, plain shower water is sent through a depending discharge neck and, via a flexible hose, to an adjustable and detachable shower head connected to said hose. Any one of the valves can be opened in a manner to bypass water through a selected container in a manner to proportionally mix the contents with the outgoing bath water for shower cleanliness and added luxury.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
212 words
Apparatus for mixing and dispensing a selected conditioning agent in a shower bath spray comprising: a housing; a manifold positioned in said housing and having an inlet and an outlet; outlet means for coupling said manifold outlet to a shower spray head; inlet means for coupling a water inlet pipe to said manifold comprising an anti-siphon valve, said anti-siphon valve having an air inlet passageway for preventing water in said manifold from flowing back into said water inlet pipe when the pressure in said water inlet pipe falls below the water pressure in said manifold, and a flexible diaphragm movable between a first position blocking said air inlet passageway when said inlet water pressure is greater than said manifold pressure and a second position enabling air to flow toward said inlet pipe and prevent reverse flow of water from said manifold when said manifold water pressure exceeds said water inlet pressure, said anti-siphon valve further including a deflector having a closed central conical portion and at least one radially-spaced opening, said diaphragm having a central opening adjacent said deflector central conical portion, said deflector opening and said diaphragm central opening defining a water flow path directing the diaphragm to said first position when the water inlet pressure exceeds the manifold water pressure.
Claim 2
Dependent Claim
212 words
Apparatus for mixing and dispensing a selected conditioning agent in a shower bath spray comprising: a housing; a manifold positioned in said housing and having an inlet and an outlet; outlet means for coupling said manifold outlet to a shower spray head; inlet means for coupling a water inlet pipe to said manifold comprising an anti-siphon valve, said anti-siphon valve having an air inlet passageway for preventing water in said manifold from flowing back into said water inlet pipe when the pressure in said water inlet pipe falls below the water pressure in said manifold, and a flexible diaphragm movable between a first position blocking said air inlet passageway when said inlet water pressure is greater than said manifold pressure and a second position enabling air to flow toward said inlet pipe and prevent reverse flow of water from said manifold when said manifold water pressure exceeds said water inlet pressure, said anti-siphon valve further including a deflector having a closed central conical portion and at least one radially-spaced opening, said diaphragm having a central opening adjacent said deflector central conical portion, said deflector opening and said diaphragm central opening defining a water flow path directing the diaphragm to said first position when the water inlet pressure exceeds the manifold water pressure.
Claim 3
Dependent Claim
51 words
Apparatus in accordance with claim 1 wherein the anti-siphon valve further includes a fixed housing and a removable insert threadably mounted therein, said insert having means defining the air inlet passageway and a separate water flow passageway downstream of the flexible diaphragm, the water flow passageway communicating with the manifold inlet.
Claim 4
Dependent Claim
64 words
Apparatus in accordance with claim 2 wherein said defining means comprises partition means separating the air inlet passageway and the water flow passageway, the partition means including a central aperture adjacent the central opening of the diaphragm and a sealing surface adjacent the diaphragm and surrounding the central aperture for co-acting with the diaphragm in said first position to seal the air inlet passageway.
Claim 5
Dependent Claim
36 words
Apparatus in accordance with claim 3 further including a plurality of sealing means between the interior of the fixed housing and the removable insert for sealing the air inlet housing and the water flow passageway respectively.
Claim 6
Dependent Claim
89 words
Apparatus in accordance with claim 1 further including a bracket having a ball mounting support pivotably mounted within a mating socket attached to said housing; a shaft extending from said ball and having a mounting ring integrally formed therewith; said shower spray head including a handle; a portion of said handle having means for removably positioning said spray head on said housing mounting ring for enabling said spray head to be fixed relative to said bracket; said bracket being pivotable relative to said housing at said ball and socket.
Claim 7
Dependent Claim
31 words
Apparatus in accordance with claim 5 wherein said mounting ring includes a flat surface which is juxtaposed with a corresponding handle flat surface when said handle is positioned on said bracket.
