ABSTRACT:
A multi-color liquid display system comprising a liquid conduit 14 and a display apparatus operatively associated therewith. A fluid circulating system is connected to the liquid conduit 14 for sequentially circulating different colored liquids 22,24 of different specific gravities through the liquid conduit to produce the visual display either as a writing sign 10 wherein a transparent liquid conduit 14 is illuminated by luminous tubing 12 or as a fountain wherein the liquid conduit is fitted with a nozzle and mounted in a fountain basin to produce a fountain spray. The fluid circulating system includes a reservoir tank 20, a pump 36, a metering chamber 30 above the reservoir and a dispensing chamber 28 below the metering chamber, a plurality of ducts 40,42 and 48, for fluidly communicating the different strata of liquids in the reservoir 20 with the metering chamber 30, and a siphon line 52 and an air breather line 50 interconnecting the metering chamber and dispensing chamber. The open ends of the ducts 40,48, the siphon line 52 and the air breather line 50 in the metering chamber 30 are in a vertical arrangement such that the liquids 22,24 are siphoned from the metering chamber for circulation in sequence through the liquid conduit.
