ABSTRACT:
A multiple selectable timer of the flowing medium type includes a housing including a medium reservoir and a catch chamber with a timing orifice for controlling the flow of the medium from the medium reservoir to the catch chamber and a metering passage for communicating between the catch chamber and the timing reservoir with the passage adapted to selectively meter predetermined portions of the flowing medium to define selected time intervals. The timer is arranged such that selective rotation of the housing in one direction loads the timing reservoir with selected intervals of timing medium and rotation of the housing in the opposite direction selectively removes predetermined portions of the timing medium.
