Abstract
Abstract:
A conservation showerhead that reduces the flow of water.
The conservation is achieved initially by the water flowing through a reduced diameter hole entering a mixing chamber and further flow restricted as water continues its flow through a spreader disc providing a fine but forceful spray.
A conservation showerhead that reduces the flow of water.
The conservation is achieved initially by the water flowing through a reduced diameter hole entering a mixing chamber and further flow restricted as water continues its flow through a spreader disc providing a fine but forceful spray.
Description
Specification:
This invention relates to using less water flow without appreciable loss of showering comfort.
It is possible to use a comnon showerhead in a conservative rnanner by adjusting both the hot and cold water valves creating less wa-ter flow resulting in a irratic spray that contains hot and cold spots and generally has insuft`icient water flow to adequately shower and further hindered by a narrow spray at foo-t level.
This invention has the object of providing a shower head that not only reduces water flow but does it consistently within varying pressures and provides a full twenty-two (22) inch spray pattern at foot level (approximately at the seven (7) foot height from the shower head) an~ free from hot and cold s~ots.
Anotner obj~c L iS to provide a novel shower head that not only conserves water but also provides a different but pleasing shower.
A further object is to provide a very simple construction -that is economical to rnanufacture and allows simple cleaning and main-tenance of parts.
Other objects are shown in the following detailed drawings in which:
FIG. 1 is a cross sectional view of the shower head parts and a sub-assembly of the swival ball and nut.
FIG. 2 is a cross sectional view of a completely assembled shower head attached to a common shower arm or water supply line.
In reference to FIG. 2, a water supply line 11 is shown connected to nut 2. Said nut 2 has an internal pipe thread that mates with said water supply line ll. Said nut 2 is connec-ted to a swival ball 4 and held together as one assembly by retaining ring 3. A seal 1 placed over the top of said swival ball 4 held firm between the said water supply line 11 and the said swival ball 4. This said seal 1 has a sufficient large hole to allow water to run freely through said seal 1 from said supply line 11. Said swival ball 4 has a primary reduction passage having a diameter of .165 inches and passing through the center of the entire length of the said swival ball 4. At the opposite end of the said swival ball 4 closest to the nozzle 7 there is a recessed mixing chamber ~ having a volume of .0719 cubic inches. This chamber has an important function in that it mixes evenly, hot and cold wa-ter thus eliminating hot and cold spots during showering. On the outer diameter oF the said mixing chamber ~ is a threaded and undercut portion of the said nozzle 7. The bottom oF the thread o-F the said nozzle 7 is flat to allow for the placement of the spreader disc 6 -&?'87 that has a number of orfices equally spaced and having a total area of .Ol91 square inches through which the water flows. Over the said spreader disc 6 is a flat washer 5 which seals the said spreader disc 6 in place after the said swival ball 4 is tightly screwed to the said nozzle 7. The furthermost output end of the nozzle 7 has a counterbore 10 which serves as an aerator and drip eliminator.
The angled inside nozzle wall 12 is angled at 7 degress 7-1/2 minutes and serves as a guide for creating a spray pattern for the liquid.
Unlike other shower heads that may reduce water flow, the important embodiment is that this invention provides a consistent reduction in water flow even with varying pressure and also be free of hot and cold spots as controlled by the mixing chamber and also provides a full spray pattern.

Claims (2)
1. A reduced flow shower head with an inlet end adapted to connect to a source of liquid under pressure having a bore at the inlet end of .165 inches diameter with an area of .0214 square inches entering a chamber located at the end of the said bore, having a predetermined volume of .0719 cubic inches and a spreader disc located after the said chamber which has a predetermined plurality of orifices totalling .0191 square inches of area which is a smaller total area than that of the area of the said bore resulting in a reduced volume flow.
2. The shower head of claim 1 further characterized in that the liquid flow through said plurality of orfices whose individual streams of liquid is guided outwardly along a predetermined angle of 7 degrees 7 1/2 minutes on the inside wall of the nozzle located after the said spreader disc, produces a twenty-two (22) inch base spray at a seven foot distance from the outlet end of the shower head.
