DEFINITION

Classification: 239/67

(under the class definition) Apparatus having control means to start or to terminate discharge of material from such apparatus or part thereof with which such apparatus or part is interconnected and which is responsive to volume, rate of flow, time or other condition which may be selectively preset or determined prior to the initiation of the flow or at some time during the flow.

(1) Note. For classification herein there must be claimed as control means something more than the mere limits defined by traversing guide, track or tethering means or the paying out or ultimate drag of a hose connected to supply means, i.e., there must be something in addition to the necessary spraying organization which is selectively-variably imposed on the system to control the flow.

(2) Note. The apparatus must go through a complete cycle of operation (i.e., start, stop, start) in accordance with the setting of the control means.
