Abstract
Abstract A keg tapping assembly comprising a tavern unit having two prongs which are sleeve-like with tapered ends to unseat the two spring closed valves of a permanently attached keg unit detachably connected to the top central hole of a keg, upon insertion into the keg unit. The invention embodies an attachment having two bores through which said prongs are detachably fitted, each bore including a one-way valve. One bore is directly connected to a tap rod insertable in the top center opening,- and the other bore is connected to a valved outlet connection at the bottom of a keg. By simply unplugging the tavern unit from the keg unit and plugging it into said attachment it is selectively usable on either a conventional single connection tap or on the older double connection tap. A one-way valve is also provided in the air connection of the tavern unit.

Claim 1
Independent Claim
216 words
An assembly for tapping a keg having liquid contents under pressure, comprising a tavern unit including a valve body having air inlet and liquid outlet connections leading into a pair of parallel sleeves having prong-like pointed ends and having an internally threaded, ring closure element; in combination with an attachment having a pair of parallel bores into which said prongs are closely and detachably fitted, one of said bores having a one-way valve which is normally kept open by one of said prongs to permit liquid to freely flow upwardly therethrough and to automatically close upon withdrawal of said one of said prongs, said attachment having external threads of said ring closure element may be screwed to form an air-tight seal, and a pair of terminal connections at the other end of said attachment, a tap unit detachably connected to the top central opening of the keg along its longitudinal axis, which unit includes a one-way valv for introducing air under pressure into said keg, and an outlet connection and valve at the bottom side opening of said keg for drawing the pressurized liquid contents out of the keg, one of said terminal connections of said attachment being connected to said tavern unit, and the other of said terminal connections being connected to said outlet connection.

Claim 3
Dependent Claim
90 words
An assembly as recited in claim 1 wherein the other of said bores of said attachment is detachably connected to a pipe for forming one of said termInal connections, the extremity of said pipe including said one-way valve for introducing air under pressure into said keg, said lastmentioned one-way valve being in the form of a sleeve of elastic material terminating in a diametrically extending flattened portion having a slit which is open by air under pressure from an external source and closed by air under pressure from said keg.
Claim 4
Dependent Claim
34 words
An assembly as recited in claim 1 wherein said air inlet connection of said tavern unit includes a one-way valve for allowing introduction of air under pressure to one of said prong-like pointed ends.
