Claim of US Patent No. 10,322,422

1. An irrigation sprinkler comprising:a turbine;
a nozzle;
a gear drive;
a reversing mechanism operatively connected to the gear drive and rotatably coupling the turbine and the nozzle, the reversing mechanism including a shift arm and a first adjustment gear having an axis of rotation;
a first stop tab connected to the first adjustment gear;
a second adjustment gear configured to selectively mesh with and unmesh from the first adjustment gear;
a user interface cap configured to interface with a tool or with a hand of a user, the user interface cap having:
a cam wall extending between a top cam wall end and a bottom cam wall end; and
a driving wall connected to the cam wall; and
an adjustment shaft connected to the second adjustment gear and positioned at least partially within the user interface cap, the adjustment shaft having:
a longitudinal axis; and
at least one protrusion extending from the adjustment shaft in a direction perpendicular to the longitudinal axis;
the cam wall is configured to drive the at least one protrusion in a direction parallel to the longitudinal axis of the adjustment shaft when the user interface cap is rotated; and
the user interface cap is configured to transition the second adjustment gear between a meshed position and an unmeshed position with respect to the first adjustment gear without requiring application of force onto or movement of the user interface cap in a direction parallel to the longitudinal axis of the adjustment shaft.
