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.

A safety shower head, comprising, in combination, a hollow main body, a thermostat secured in said hollow main body, for expanding when the water temperature is too high, to close an orifice in a piston of a shut-off valve, to prevent hot water flow on a bather immediately, and a relief valve secured in an off-set portion of said main body, for releasing the hot water away from the thermostat, after the inlet source of hot water is shut off, so as to enable normal use of said safety shower head again; the outer periphery of an end of said thermostat being fixedly secured to the inner periphery of said hollow main body, and a plurality of radially spaced-apart openings in a skirt of said piston normally receive water when said safety shower head is in use, the water normally passing through a central opening in an inner wall fixedly secured, at its outer periphery, to the inner periphery of said hollow main body, and said skirt of said piston is fixedly secured to a piston rod, and the opposite end of said piston rod threadingly receives an adjustment screw for adjusting the tension of a coil spring received on said piston rod, and one end of said coil spring urges against a disc fixedly secured to said piston rod, and the opposite end of said coil spring urges against the rear of the face of said hollow main body, and said adjustment screw is freely received in an opening in said face of said hollow main body.
