ABSTRACT:
A coin-operated purified water dispensing machine. A pair of vertically stacked transparent fill tubes are mounted in a cabinet in visually exposed relation to a consumer operating the machine. A water dispensing nozzle is associated with each fill tube and is protected by a shroud that is specifically configured to engage the upper portion of a container to aid the consumer in properly positioning the container to be filled. The consumer activates the machine by placing the required coins in a coin chute. Acceptance of the coins effects rotation of a rotatably mounted cam that is fixedly secured to and in axial alignment with a four-way valve that in turn controls the flow of water into and out of the machine. The fill tubes are capped by end plug members having specific sealing and a piston is slidably mounted for reciprocating movement within each fill tube to effect vending of a precise volume of purified water.
