ABSTRACT:
A liquid dispenser for dispensing liquid from an inverted bottle into a tank at times when water in the tank drops below a buoying level. A hollow annular stationary member closes off the bottle's neck and has an annular diaphragm leading to a tube with seats at its upper and lower ends. A movable member has two portions that are slidable in the said tube and are joined by a measuring portion. It seats against one seat in its upper position with the measuring portion then wholly above the tube and against the other in its lower position, with the measuring portion then wholly below the tube, and it is moved between them by the change of water level in the tank. This movement is aided with a buoying skirt having an annular chamber that is normally filled with water and drains only after falling; the same chamber helps to dispose the measured charge of the other liquid.
