Abstract
Apparatus including a monitor and a portable ground base comprising a liquid-carrying conduit having an inlet end and an outlet end. The inlet end is adapted to receive a liquid (such as water) from a supply, and the outlet end is attached to the intake of the monitor. The conduit of the base includes an intermediate portion that is normally close to the support or ground when the ground base is in the normal operating position. Mounted within the conduit is a valve that is movable between a closed position and an open position. The valve is biased toward the closed position by a mechanism including liquid flow through the conduit and a spring. A trip catch is connected between the valve and the conduit for releasably holding the valve in the open position to permit flow through the conduit. A trip is mounted on the ground base and connected to the trip catch, the trip being operable to sense tilting movement of the ground base and to disengage the catch, thereby enabling the valve to move to the closed position and block liquid flow.
