ABSTRACT:
Timing apparatus comprising a housing having a fluid-containing conduit and a body movable in the conduit under the influence of gravity includes a valve for controlling circulation of fluid in the conduit and thereby controlling the time elapsed during movement of the body between preselected locations. The housing supports a magnet for sliding movement when the body descends to its lowermost location and a member responsive to such magnet movement initiates audible output indication.
