Today in 1917, US Patent 1246803 A was issued, an invention of Giuseppi Doti, for his “Beer-Pipe Cleaner.” There’s no Abstract, although in the description it includes this summary:

This invention relates to a beer pipe cleaner, and the primary object of the invention is to provide a device, by means of which any one or a number of beer pipes or coils may be cleaned, by being first subjected to warm water, after which the beer pipes are flushed or rinsed by cold water.

A further object of this invention is to provide a frame work, which is constructed of a plurality of pipes having branches, and to connect the frame work of pipe structures to a city water supply pipe, and also to an ordinary barrel or keg tap, so that warm water may be forced upwardly out of a barrel into the pipes of the frame work, and outwardly therethrough into and through the beer pipes, for cleansing the beer pipes, after which the flow of hot water is cut oil, and valves for controlling the cold water are opened which permit cold water to flow through the pipe frame work and through the beer pipes.
