Abstract: 4690. Wright, J. R. Feb. 22. Beer and other beverages, raising and drawing-off. -Counter fountains for aerating and drawing-off beer and other beverages are constructed as shown in side elevation in Fig. 2, and in horizontal section in Fig. 4. The liquid to be aerated flows through the pipe E into the glass container C, wherein it is aÙrated by carbonic-acid gas from the steel tube D, the gas passing first into a cylinder I wherein is a spring valve with a rod projecting from the cylinder, which rod is forced downwards by a projection on the plug tap A<1> when the tap is turned, so that gas passes into the pipe H and thence obliquely into the vessel C so as to both aerate and agitate its contents. When the aeration is complete, the gas in the top of the container is allowed to escape past a spring valve J, by opening either of the valves K<1> or K<2>. In the first case the excess of gas passes to the draw-off nozzle N and further aÙrates the liquid as it is being drawn off, and in the other case the gas passes down the pipe K<3> to the beer cask and forces the beer up through the tube E.
