6 Claims. (Cl. 299144) This invention relates to an improved shampoo head.
It is an object of this invention to provide a self-closing shampoo head.
It is still a further object of this invention to provide a shampoo head which may be manipulated by one hand of the user and opened and closed at will.
It is still a further object of this invention to provide a shampoo head of a self-closing type wherein a minimum of parts are required reducing cost'and increasing longevity.
It is still a further object of this invention to provide a shampoo head wherein a single element function to shut oil flow through said head while also preventing leakage therefrom.
Other objects and advantages will be readily apparent from the following description:
In the drawings:
Figure 1 is a diagrammatic view of the component elements of the shampoo head.
Figure 2 is a sectional view of the head in the closed position. a I
Figure} is a view similar to Figure 2 of the head in the open position. 7 p
The shampoo head generally designated 10 is supplied water through flexible tube 12. Water is supplied to tube 12 from any suitable source such as a wash basin or the like or for example in place of spray nozzle in Bletcher et al. Patent No. 2,608,412 permitting regulation of the temperature of the water While discharging through the spout outlet and then diversion of flow through the shampoo head by opening same.
The tube 12 has a nipple 14 at its extremity which limits movement of collar 16 towards the extremity of the tube. The collar 16 has a threaded end 18 which screws into the rearmost extremity of housing 20 wherein the valve means is housed. The foremost extremity of housing 20 is provided with external threads 22 to receive the internally threaded cap 24.
The housing 20 has a chamber 26 formed therein adjacent the foremost extremity which forms a valve chamber. A resilient valve seat 28 has its outer periphery clamped between cap 24 and housing 20 forming a gasket. This valve seat is preferably formed of rubber or similar flexible water resistant material and has a plu rality of apertures 30 therethrough. For each aperture 30 there is provided on the foremost side of the valve seat a hollow projection 32. In this embodiment the foremost extremity of the projections 32 has three minute outlets 34 communicating with the hollow interior of the projections to more finely divide a stream of water flowing therethrough. These projections pass through suitable apertures 35 in cap 24.
An actuating member 36 is provided outside cap 24 having a plurality of apertures 38 one for each projection 32. The actuating member has a central post 40 which projects through opening 42 in cap 24 and through United States Paten 2,862,766 Patented Dec. 2, 1958 central aperture 44 in valve seat 28. The aperture 44 forms a snug fit with post 40 preventing leakage around the post.
The post 40 at its inner extremity receives valve member 46 which is held thereon by engagement with shoulder 48 and nut 50 which screws onto the threaded reduced extremity of post 40.
The valve member 46 has a plurality of apertures 52 which apertures arenot in alignment with the apertures 30 in valve seat 28. When the valve member 46 is held against the valve seat 28 it covers apertures 30 preventing flow therethrough. Likewise valve seat 28 blocks apertures 52 preventing flow therethrough.
A coiled spring 54 has one extremity bearing against valve member 46 and the other against shoulder 56 in chamber 26 which urges the valve member into contact with the valve seat.
The housing 20 has a plurality of ribs 58 inside chamber 26 which guide the spring 54.
In operation water flows through tube 12 into chamber 26. When spring 54 is urging valve member 46 into contact with valve seat 28, flow from chamber 26 is shut oif. When the operator holds housing 20 in his hand and depresses actuating member 36 by one or more fingers the device takes the position seen in Figure 3. The valve member 46 is moved relative to the valve seat 28 permitting flow through apertures 52 between the a valve member and valve seat through apertures 3t? into the hollow projections 32 and outlets 34 in the extremity thereof in a multitude of small streams suitable for shampooing.
While what hereinbeforehas been described is thepreferred embodiment of this invention, it is readily apparent that alterations and modifications may be resorted to without departing from the scope of this invention and such alterations and modifications are intended to be included within the scope of the appended claims.
