Shower head and liquid agent dispensing attachment

Claim 2

Apparatus for selectively mixing and proportioning liquid agent with pressurized liquid, comprising in combination: a hollow enclosure having first and second openings at oppoSite sides thereof and a smaller diameter orifice extending through said body generally transversely of the axis of the first and second openings; a valving member rotatably received within said body and including a first channel extending through said valving member generally parallel to the axis of said body openings and a second channel opening having a restricted portion extending parallel to said first channel opening; lever arm means connected to said valving member for rotating the same; wall means within said body member having an elongated opening therein so located that said second channel opening has an end in communication with said elongated opening throughout the full range of valving member rotation and one end of the first channel interconnects with the elongated opening only throughout a restricted range of rotation of the valving member; a source of supply of the liquid agent connected to the body member over one of the orifices outer ends for communicating with the supply of liquid agent; said valving member including an orifice extending transversely therethrough and passing through said second channel such that at one position of valving member rotative adjustment a through communication is achieved from the liquid agent, orifices, the second channel and the external air whereby at this position of adjustment pressurized liquid flowing through the second channel in aerated and liquid agent is admixed therewith.

Claim 3

Soaping-rinse apparatus, comprising in combination: a spray head; a supply of liquid soap; a supply of pressurized water; and selectively adjustable valving means interconnected with said pressurized water supply, said liquid soap supply and said spray head, said means being adjustable to provide selectively, an aerated liquid soap-water mixture or water over a variable range of emitted pressure.

Claim 4

Soaping-rinse apparatus, comprising in combination: a spray head; a supply of liquid soap; a supply of pressurized water; and selectively adjustable valving means interconnected with said pressurized water supply, said liquid soap supply and said spray head, said means being adjustable to provide selectively, an aerated liquid soap-water mixture or water over a variable range of emitted pressure.

Claim 5

Soaping-rinse apparatus as in claim 1, in which a single lever arm extending externally of said valving means is manipulable to provide full adjustment of said valving means.

Claim 6

Apparatus for selectively mixing and proportioning a first liquid with a pressurized second liquid, comprising: wall means defining a hollow enclosure having first and second openings in said wall means opposite sides thereof for connection to receive the pressurized liquid and to serve as an outlet, respectively; a fitting on said wall means for connection to a supply of said first liquid; said wall means including an internal wall surface with an opening therein communicating with said second opening in said wall means, a first orifice in said wall means having one end terminating in the air and the other end terminating in said internal wall surface, and a second orifice in said wall means having its two ends terminating in the fitting and internal wall surface, respectively; a valving plate received within the hollow enclosure and having a surface in flush contacting relation with the internal wall surface of said wall means; said valving plate including a first channel therethrough from the surface contacting the internal wall surface to the opposite, a second channel larger than said first channel and also extending from the surface contacting the internal wall surface to the side opposite, and a pair of orifices extending from said surface contacting the internal wall surface to the first channel and disposed from one another on said surface contacting the internal surface at the same spacing as the orifices in said wall means; and means connected to said valving plate for moving said plate in the plane of contact with said internal wall surface throughout a range in which the plate orifices are aligned with the wall means orifices at one position and said second channel communicating with said wall surface opening for a portion of said range and said first channel being in continuous communication over said full range.

Claim 7

Apparatus for selectively mixing and proportioning a first liquid with a pressurized second liquid, comprising: wall means defining a hollow enclosure having first and second openings in said wall means opposite sides thereof for connection to receive the pressurized liquid and to serve as an outlet, respectively; a fitting on said wall means for connection to a supply of said first liquid; said wall means including an internal wall surface with an opening therein communicating with said second opening in said wall means, a first orifice in said wall means having one end terminating in the air and the other end terminating in said internal wall surface, and a second orifice in said wall means having its two ends terminating in the fitting and internal wall surface, respectively; a valving plate received within the hollow enclosure and having a surface in flush contacting relation with the internal wall surface of said wall means; said valving plate including a first channel therethrough from the surface contacting the internal wall surface to the opposite, a second channel larger than said first channel and also extending from the surface contacting the internal wall surface to the side opposite, and a pair of orifices extending from said surface contacting the internal wall surface to the first channel and disposed from one another on said surface contacting the internal surface at the same spacing as the orifices in said wall means; and means connected to said valving plate for moving said plate in the plane of contact with said internal wall surface throughout a range in which the plate orifices are aligned with the wall means orifices at one position and said second channel communicating with said wall surface opening for a portion of said range and said first channel being in continuous communication over said full range.

Claim 8

Apparatus as in claim 4, in which the enclosure first opening incluDes a collar removably retaining said valving plate within said enclosure.
