Abstract: 702,535. Delivering measured quantities of liquids. PEERLESS AUTOMATIC DISPENSERS, Ltd. Dec. 17, 1951 [Dec. 15, 1950], No. 30682/50. Class 106(5) A liquid-dispensing device, particularly for use in coin-operated apparatus as described in Specification 702,530, comprises a measuring chamber 1 extending into the lower part of a storage vessel 2 and a valve rod 5 which carries an inlet valve 13 and outlet valve 14 and is normally pressed outwards by a spring 28 so that the outlet valve is closed and the inlet valve is open to allow liquid to fill the chamber through the inlet valve block 9 and passages in the valve 13 and to rise in a narrow-bore air vent 27 to the level of the liquid in the storage vessel. When delivery is required, the valve rod is pressed inwards manually or by mechanical or electro-mechanical means for a set interval of time to open the outlet valve 14 and allow discharge through a nozzle 26, the inlet valve being closed during this time. The time interval may be sufficient for the chamber to empty completely or the valve block 9 may be screwed inwards to limit the amount of opening of the outlet valve so that only a portion of the chamber contents are delivered in the given time. Since the liquid in the chamber 1 is isolated from the storage vessel, the rate of flow from the outlet is not affected by varying head of liquid in the storage vessel.
