Claim 2

A bathing fixture comprising a housing having a water supply inlet communicating with a chamber therein, a valve seat providing an outlet opening for said chamber, a discharge nozzle connected to said housing and in communication with the outlet opening formed by said valve seat, temperature responsive power means located in said chamber, a valve member connected to said power means for movement thereby upon an increase in temperature of the water flowing through said chamber above a given operating temperature, and means in said chamber supporting said power means to enable the latter to move said valve member toward said valve seat to close the opening therethrough when the temperature of the water in said chamber reaches said given operating temperature, one end of said housing being provided with a nipple for connecting a water supply pipe to said housing and forming said water supply inlet, said nipple and said valve seat having a common central axis, and said supporting means supporting said power means between said nipple and said valve seat with one end of said power means fixed in said chamber at a place adjacent to the discharge end of said nipple, said valve member being connected to the other end of said power means and movable along said common central axis toward said valve seat.

Claim 3

A bathing fixture as defined in claim 1, including an adapter connected to said housing outwardly of said valve seat and in communication with the outlet opening formed by said valve seat to provide a liquid passage between said valve seat and said discharge nozzle, said valve seat being constituted of a separate annular element secured between said adapter and said housing, said supporting means comprising a bracket secured at its outer end to said valve seat and extending longitudinally in said chamber to a point short of the inner end of said nipple, and said power means being mounted on the inner end of said bracket, whereby said valve seat, bracket and power unit is supported as a removable unit by said housing and adapter.

Claim 4

A water supply safety device adapted to be connected between a water supply pipe and a discharge nozzle, said device comprising a hollow housing having an entry end connectible to the water supply pipe to permit the flow of water therethrough, a valve seat provided in said housing in spaced relation to the entry end thereof, temperature responsive power means located in said housing between the entry end thereof and said valve seat, means fixedly securing one end of said power means adjacent to the entry end of said housing, and a valve member connected to the other end of said power means for movement thereby in the direction of flow of the water through said housing upon an increase in temperature of the water flowing through said housing above a given operating temperature, said power means being constructed and arranged to move said valve member toward said valve seat to close the same when the temperature of the water in said housing reaches said given operating temperature, the entry end of said housing comprising a nipple for connecting a water supply pipe to said housing, an inturned flange provided on the inner end of said nipple and defining an entry opening having a diameter less than that in the discharge end of the water supply pipe and such as to reduce the pressure of the water supplied through such entry opening into said hollow housing.

Claim 5

A water supply safety device adapted to be connected between a water supply pipe and a discharge nozzle, said device comprising a hollow housing having an entry end connectible to the water supply pipe to permit the flow of water therethrough, a valve seat provided in said housing in spaced relation to the entry end thereof, temperature responsive power means located in said housing between the entry end thereof and said valve seat, means fixedly securing one end of said power means adjacent to the entry end of said housing, and a valve member connected to the other end of said power means for movement thereby in the direction of flow of the water through said housing upon an increase in temperature of the water flowing through said housing above a given operating temperature, said power means being constructed and arranged to move said valve member toward said valve seat to close the same when the temperature of the water in said housing reaches said given operating temperature, the entry end of said housing comprising a nipple for connecting a water supply pipe to said housing, an inturned flange provided on the inner end of said nipple and defining an entry opening having a diameter less than that in the discharge end of the water supply pipe and such as to reduce the pressure of the water supplied through such entry opening into said hollow housing.

Claim 6

A safety device as defined in claim 3, in which said nipple is internally threaded up to said inturned flange, the length of said thread being less than the length of the screw thread provided on the discharge end of the water supply pipe.
