DEFINITION

Classification: 141/383

(under subclass 311) Apparatus including a receiver or receiver coacting means having a readily separable means for fixedly coupling the receiver and supply means together.

(1) Note. For classification in this group the securing means for joining receiver and supply must be set forth by

more than name only, i.e., the specific end configuration must be set out, not a mere statement that it is a coupling. Screw threaded or friction held couplings are not considered sufficient for classification in this class in the absence of a claimed receiver-dispenser combination.

(2) Note. Most of the patents in this and the indented subclasses relate to hand held and supported supply means of the grease gun type. The receiver and supply securing means is not intended to be a coupling means whereby the supply means after coupling is supported by the receiver but rather a pressure retaining connecting means.

311, for special receiver-dispenser coacting means as for example, critical angles, sharp edges, and other such special configurations.

363+, for filling arrangements wherein the filling supply is supported by the receiver as by suspension means for example. 382, for supply means having flexible hoselike conduit means provided with receiver engaging means.

392, for filling heads, per se.
