Claim 6

Apparatus according to claim 1 wherein said coupler head includes an externally threaded portion, a collar threadedly engaging said threaded coupler head portion and having an inwardly directed annular flange defining a central opening, said moving means including a tube receivable through said openIng and carrying a flange inwardly of said collar engageable against the flange on said collar, said biasing means normally maintaining the flange carried by said tube in engagement against the flange carried by said collar.

Claim 7

Apparatus according to claim 1 wherein said gas passage means includes a bore through said coupler head offset from the central axis thereof, said biasing means including a spring engaging between said sleeve and said coupler head.

Claim 8

A liquid dispensing apparatus for use with a keg or like container having top, bottom and side walls with an opening in at least one of said walls comprising: a keg adapter having a generally cylindrical body adapted to be secured within the keg wall opening and having gas and liquid passageways extending therethrough for the respective transfer of gas into the keg and of liquid out of the keg, normally closed valve means in said gas and liquid passageways, said valve means including a valve body rotatable in a plane extending substantially normal to the axis of said body between a first position sealing said passageways and a second position opening said passageways, a dispensing coupler unit including a coupler head having gas and liquid passageways therethrough, means for releasably securing said coupler head to said keg adapter, means carried by said coupler head for rotating said valve body into said second position and locating the respective gas and liquid passageways in said coupler and said adapter in communication one with the other, a member movably carried by said coupler head, means carried by said coupler head for biasing said member for movement into a first position, a normally closed valve carried by said coupler head in its liquid passageway, and means extending exterior of said coupler head for selectively moving said member against said bias into a second position to open the normally closed valve carried by said coupler when said coupler head is secured to said adapter, said moving means including inner and outer concentric tubular means with said inner means forming a continuation of said liquid passage in said coupler head, said coupler head having a shoulder, means securing said moving means to said coupler head including a projection carried by said outer tubular means and engageable against said shoulder, said biasing means normally maintaining said projection in engagement against said shoulder.
