DEFINITION

Classification: 137/128

(under subclass 124) Apparatus having a main siphon through which the major portion of the fluid is discharged and an auxiliary siphon which operates to start or stop fluid flow through the main siphon, or, after discharge of the main siphon, restores some or all of the main siphon operating means to a position permitting a subsequent discharge.

(1) Note. In series arrangements of plural tanks and siphons wherein one siphon discharges into a tank which is emptied by a second siphon, the first siphon is not regarded as a starter for the second when discharge of the second siphon results merely upon accumulation of sufficient fluid in the tank to permit such discharge, and patents for this subject matter are not included in this or the indented subclass.

SEE OR SEARCH THIS CLASS, SUBCLASS:

132+, for periodic siphons, or those which discharge as often as a supply sufficient for starting is accumulated.

142+, for other siphon starting means.
