ABSTRACT:
An anti-scald apparatus for a tub and shower single control faucet which incorporates a novel cam and cam follower arrangement on the hot and cold water valve means which permits substantially more than 180 degrees of rotation of the control handle. Adjustable temperature stops provide both a comfort stop for normal use and a safety stop which can be reached only by activation of a release button carried by the faucet handle by means of which the comfort stop may be overridden by continuing the rotation of the handle.
