Abstract
Abstract Beer tapping attachments comprising a permanent keg unit including two normally closed spring-biased one-way valves to which unit is detachably secured a valve body which also includes two registering spring biased one-way valves, one connected to a source of air under pressure and the other to a beer spigot. All four valves are yieldably opened when the valve body is connected to the keg unit. There is also provide an adapter, also including two-spring biased, registering one-way valves and bores leading thereto to accomodate the tubular prongs of a commonly used attachment, whereby when the adapter is unplugged, the valves thereof will close and prevent escape of air or beer.

Claim 1
Independent Claim
178 words
In combination with a beer keg having a keg unit mounted axially at one end, said unit including two spring-biased valves in ports of said unit through which compressed air and beer flow respectively; and a valve body attachment including two correspondingly positioned spring-biased one way valves, the corresponding valves mutually actuating each other within ports leading to a source of air under pressure and to a beer spigot, respectively, whereby when the valve body attachment is detachably fastened to said keg unit, it will effect opening of all four of the spring pressed valves of the attachment and keg unit to permit the flow of air under pressure and beer, said valve body attachment being in the form of an adapter having two vertically extending parallel bores and a plug-in tap unit having air and beer connections to a source of air under pressure and to a beer spigot, which plug-in unit comprises a pair of tubular prongs with tapered ends which are detachably and snugly fitted to said parallel bores of said adapter above said valves.
