Today in 1953, US Patent 2628009 A was issued, an invention of Edward D. Idzi, for his “Tap Box.” There’s no Abstract, but in the description it states the following:

My invention consists in a new and useful improvement in tap boxes and is designed to provide improved apparatus for chilling and dispensing draught beer tapped from kegs. The particularly novel and useful features of my improved device are the non-metallic composition beer conduits composed of a suitable plastic, such as Lucite, with suitable coupling means of the same composition for connecting the conduits to the kegs and by which the beer is conducted from the keg to the dispensing faucet entirely free of any contact with metal; the novel refrigeration system by means of which the temperature of the beer is reduced to the desired degree by being subjected to the effect of a refrigerant throughout the entire course of flow from the keg to the faucet; novel chilling units through which the beer flows immediately prior to reaching the faucets; novel mounting means by which the chilling units, beer conduits and faucets are disposed in the tap box; a freeze box for making ice, associated with the chilling units; and a beer glass trackway associated with the freeze box and having a blower for chilling the glasses passed there along.
