Today in 1882, US Patent 253683 A was issued, an invention of Peter J. Catterall and Edward Birch, from Manchester, England, for their “Apparatus for Raising Beer.” There’s no Abstract, but the application states their “invention relates to apparatus for raising valves, through one of which the liquid is admitted to the chamber, and through the other the liquid is forced to the bar or delivery-tap” and there “is a section of the three-way tap that admits and discharges the water used to raise the beer or other liquid.”
