This invention relates to a thermostatic water
control for bath tubs, kitchen sinks, wash basins,
showers, etc.
An object of the invention is the provisionfof.
simple and eillc'lent means for blending togetherv
hot and cold water when desired, or when the
operator desires he can easily adjust the mech
anism for discharging only cold water.

hub portion 4 on the inner end of which is the
reduced cylindrical extension 5. Threaded into
valve sleeve 2 is thehot water pipe 8, and thread

A cylindrical rotary valve 8 is mounted within
the valve sleeves 2 and 3.- 'I'his rotary valve has
