nozzle 102a from pointing toward their positions when the timer 109 times out discharge is actuated as follows latch 110 is released as a notch on a cam wheel becomes aligned with a finger on the latch as previously described for items 68 67 and 66 in fig1 and 2 with the latch released spring 113 forces shaft 111 and plunger 105 upward thereby forcing water upward within cylinder 104 and out through openings 117 clearance between shaft 111 and the opening 118a in the upper end of upper cylinder appendage 118 is designed to be minimal to prevent excessive leakage of water the rotor assembly 102 is rotatably carried on the upper appendage 118 of cylinder 104 having o rings 119 to provide a seal between rotor 102 and appendage 118 above and below openings 117 such that water forced through openings 117 must exit the system through a passage 120 and nozzle 102a of the rotor assembly at any time during discharge of the pump a player may stop the discharge by pressing downward on handle 112 to override the bias of spring 113 thereby stopping or reversing the upward motion of plunger 105 a secondary indexing mechanism best understood with reference to fig5 and 7 provides positive alignment of the nozzle 102a with a player position at the time of discharge this mechanism comprises indexing slots 102d in the opening 102e in the upper end of rotor 102 through which shaft 111 protrudes when plunger 105 is in the lower position indicated in dashed lines by the numeral 114.
