DEFINITION

Classification: 137/223

(under the class definition) Apparatus comprising valved inflation stems of the type attached to pneumatic tires and analogous inflatable articles, including filling and/or relief extensions of such stems, valved filling chucks or the type attached to pressure fluid supplying conduits and employed to inflate such articles by means of the inflation stems, and combinations of such inflation stems and filling chucks.

(1) Note. Relief and filling extensions to be attached to inflation stems have means to hold open the valve normally present in such stems.

(2) Note. The claiming of a source of supply of inflating

fluid by name only does not exclude patents otherwise classifiable herein.
