When rod y21 moves up, it strikes lever lfto 'An inverted cup 30 is Vvfixed to the upperk'end Integral 'with' bracket 2-5 is 'a bracket A4V|l`which1 pivotally mounts at -4I, a latch in the form of av bellcrank 42'having a cro'sspin 43 which cooperates with the upper and lower cams w44 and 4'5 of a plate 46 fixed to the lower end of link 20'to provide a; latch for thisl link; The bell` crank 42 constantly tends to rock counter-clockwise n its pivot 4I and functions to delay the movementof link 20 by engaging either of the cams 44,45 of plate 46 on link 20. l

`3- (ci. 1er-rss) If water is admitted to a level above cup 2 l, that cup will lose thegreater portion of its effective weight; being completely submerged, and will no "f longeryoppose the-counterweight. However, nothing will happen until the water level becomes high enough to raise the vupper cup 30 to overcome the weight of bellcrank 4.2 and release the latch at i 43-45, whereupon thecounterweightv 21 drops yneedle valve |13 pivotally lconnected at its lower end I4 to a.V countcrweight` lever l5 .pivotally v3() open the valve', andwhenv rod 21 moves down, it frees lever l5'to close the valve.

Ifvenough water be drawn off so that the water level drops belowthe upper edge'of cup 2|, suiiilcientto give that-cup weight well in excess of counterweight 21 [and the retaining force produced by the latch acting at 43-44, then the valve will be opened with a snap action because cup 2l will drop, after a time delay, since by this time it has suiiicient weight, whereupon the linkage will move and the valve will open fully.
Not untillower cup 2| has l attained a considerable weight willit release the latch at 43-44 to open the valve, and not until the buoyant force on cup., 30 is consider-able in amount, will the latch at'43-45 be yreleased to permit the valve to-close.
