Today in 1960, US Patent 2936100 A was issued, an invention of Victor H. Chatten, assigned to Anheuser-Busch, for his “Dispenser For Carbonated Beverages.” There’s no Abstract, although in the description it includes this summary:
This invention relates to apparatus for dispensing a gas-charged liquid from a container and is particularly directed to apparatus for dispensing a carbonated beverage, for example, beer, from a conventional keg.
It is the principal object of this invention to provide an insert member which can be introduced into the interior of the container through an opening therein which member includes a cavity containing liquified gas under pressure and which member also contains a regulator device for introducing gas from the cavity into the container, the action of the regulator being controlled from a member accessible exteriorly of the container. Another object is to provide dispensing apparatus of this type in which the insert member includes a passage for delivery of fluid from the interior of the container. A more detailed object is to provide dispensing apparatus of this type in which means accessible exteriorly of the container are provided to control flow of gas from the cavity to the interior of the container and also to control flow of liquid from the interior of the container.
