ABSTRACT:
This shower head serves to replace existing shower heads, and when the water becomes too hot for safety, it is so designed, that it will stop the hot water flow from striking the bather. It consists primarily of a fixed thermostat, which, when expanded, will cause a disc attached to a piston to be, by water pressure, urged against an opening, to cut off the water flow on the bather, and the hot water is then shut off at its source by the bather. The head further includes a lower passageway leading to a depressible relief valve, for releasing the hot water from the thermostat area, so as to enable the thermostat to reset.
