(under subclass 63) Apparatus in which there is provided an additional means which controls the flow regulating means regardless of the demand of the mechanism responding to the discharged fluid, or lack thereof.
(1) Note. The additional control means may be either manually or automatically operated. In those systems including a timer or clock mechanism, such mechanism is the overriding second control means since it will not permit the flow of fluid to the sprayers until the selected time is reached, or regardless of the demand placed upon the system, or it will positively shut off the fluid when the set time period has elapsed, also regardless of the fact that additional demand is required externally of the system.
