Claim of US Patent No. 10,029,265

1. An irrigation sprinkler comprising:an outer case having a first end, a second end, and a case interior; and
a riser assembly having:
a riser housing having a first end and a second end, the second end of the riser assembly positioned within the case interior and configured to receive pressurized water from the case interior;
a turbine positioned within the riser housing and configured to rotate in response to water entering the second end of the riser housing;
a gear reduction positioned within the riser housing and operatively connected to the turbine;
a reversing mechanism operatively connected to the gear reduction and configured to transition between a forward configuration and a reverse configuration, the reversing mechanism including an input gear configured to rotate in response to rotation of the turbine, a first output gear configured to selectively mesh with the input gear;
a ring gear configured to mesh with the first output gear; and
a rotatable nozzle positioned on the first end of the riser housing and rotatably connected to the ring gear;
wherein the first output gear is configured to mesh with the input gear and with the ring gear to drive the ring gear in a forward rotation direction when the reversing mechanism is in the forward configuration, and wherein the first output gear is configured to mesh with the ring gear and to move away from the input gear and unmesh from the input gear when a user manually rotates the ring gear in the forward direction when the reversing mechanism is in the forward configuration.
