Today in 1903, US Patent 718759 A was issued, an invention of John D. Hendrix, for his “Beer-Cooler.” There’s no Abstract, although in the description it includes this summary:
This invention relates to beer-coolers, and has for its object to provide an inexpensive, in durable, and efficient device adapted to contain a given quantity of beer and provide a cooling-receptacle in communication with the keg or source of supply and from which the beer may be drawn by means of a faucet or other convenient discharge.
Another object of the device is to provide means whereby the receptacle may be charged with pressure through the medium of a handpump or from a gas-reservoir.
A still further object is to provide an improved closure for the receptacle, whereby the top may be conveniently attached and detached and when in position withstand the strain to which a device of this character would be subjected owing to excessive pressure caused by the charging thereof.
A further object is to provide a refrigerator for the cooling-receptacle which is adapted to contain the same, so that the outer walls of said receptacle will have the full benefit of the refrigerating material, which in this particular instance will preferably be ice.
