Abstract
Abstract A programmable water valve is provided wherein a twenty-four hour electric time controls the operation of a solenoid actuated valve. An interval of time is selectable in each day for actuation of the valve. In order to provide operation of the valve on alternate days a dividing circuit is used and a selector is provided to select either daily or alternate day operation. An indicator light is provided to indicate when the valve is actuated.

Claim 1
Independent Claim
272 words
A timed water valve responsive to a source of electric power comprising: a water inlet; a water outlet; a solenoid actuated valve means for controlling fluid communication between said inlet and said outlet; elctrical timer means having a 24 hour periodic cycle, said timer means including first and second associated switch means which are respectively closed at sequential predetermined first and second times driving each said cycle, said first time being prior to second time in each cycle; a third normally-open switch means; means for connecting said third switch means in a series circuit with said solenoid actuated valve means and said source of electrical power for controlling the turning on of said valve means; means coupled to said first and second switch means and responsive to the closure of said first and second switch means for closing said third switch means for a first time period beginning at said first time and ending at said second time for enabling said valve to be turned on for said first time period in each cycle; a fourth switch means; divide-by-two means coupled to said first switch means and responsive to the closure of said first switch means for closing and opening said fourth switch means on alternate second time periods of 24 hour length beginning at said first time in one said cycle and ending at said first time in the next said cycle; a fifth manually actuatable switch means for selectively placing said fourth switch means in said series circuit, whereby said valve may be selectively turned on for said first time period only in alternate ones of said 24 hour cycles.
