Abstract

A multiple outlet water timer having an inlet and a plurality of outlets each having its respective control valve. The timer is operated by a clockwork mechanism with a cam on the clockwork mechanism case, a cam follower for each valve and each cam follower is individually adjustable so that the flow of water through each outlet is adjustable independently of the other outlets.

Claims

1. A multiple outlet water timer having a circumferential body, an inlet to the body and a plurality of outlets circumferentially arranged around the body, the flow to each of the outlets being controlled by its own respective valve, a case containing a clockwork timer mechanism having a shaft non-rotatably mounted in the body the clockwork timer being drivingly connected to said case which thus rotates about the said shaft, said case having a circumferential wall and a base, a cam on the base of the case co-operating with a cam follower for each respective valve, characterized in that each cam follower is adjustable radially of the clockwork mechanism case so that the duration of opening of its associated valve is individually adjustable, the valves being opened in sequence as the cam on the case of the clockwork mechanism actuates the valves.

2. A multiple outlet water timer as defined in claim 1 wherein the inlet opens to a circumferential chamber, each valve controlling the flow from the circumferential chamber, each valve has associated therewith a push rod which is adapted to be actuated by said cam follower, and each valve is opened by water pressure after the push rod is actuated by the cam follower.

3. A multiple outlet water timer as defined in claim 1 characterized in that each cam follower is adjusted by a slider slidable circumferentially on the surface of the body of the water timer.
