DEFINITION

Classification: 141/206

(under subclass 198) Filling apparatus including a flow controlling means which is opened by hand for commencement of flow to the receiver and having (1) means responsive to a predetermined quantity of contents material in the receiver and (2) some hand controlled means for terminating the flow to such receiver. The manual means and the level responsive means do not necessarily act to control the same valve.

(1) Note. In this and the indented subclasses are classified for the most part filling station dispensing nozzles which are hand held and/or supported and controlled for at least a portion of the filling period and such subcombinations thereof which include claims to the level or overflow responsive means and which have the readily separable dispenser-receiver disclosure.

(2) Note. With reference to (1) Note above, and subclasses 210+ it should be noted that many of the patents in the fore said group claim only for example, the self-opening and level responsive valve means and make no mention of the manually initiated or controlled valve serially preceding such valve. Stated differently many of the patents in subclasses 210+ disclose the required combination for the group; however, they claim only an attachment for the ordinary manually controlled dispensing nozzle.

199+, appropriate subclasses for funnel type supply means having a manually opened flow controller and level responsive cut-off means.
