Claims13
A rotary sprinkler comprising:
- a sprinkler housing adapted for connection to a supply of irrigation water;
- a spray head for outward projection of an irrigation water stream and supported for rotation relative to said housing;
- a rotary drive assembly for rotatably driving said spray head;
- a reversing mechanism for reversing the direction of said spray head rotation;
- and
- a disengagement mechanism for disengaging said reversing mechanism, said disengagement mechanism comprising a biased member shaped and sized to engage a trip shaft of said reversing mechanism and disengage said trip shaft when depressed;
- wherein said biased member includes:
- a locking groove shaped to secure said trip shaft for rotation;
- and a biasing spring positioned to bias said locking groove against said trip shaft.

A rotary drive sprinkler comprising:
- a sprinkler housing adapted for connection to a supply of water;
- a spray head for outward projection of an irrigation water stream and supported for rotation relative to said housing;
- a water driven gear drive transmission for rotatably driving said spray head to sweep said irrigation water over surrounding terrain;
- and
- a reverse assembly including a shift mechanism movable between forward and reverse drive positions for respectively shifting said gear drive transmission between forward and reverse drive rotation directions for correspondingly reversing the direction of rotatable driving of said spray head, said reverse mechanism being operable by way of a trip shaft;
- and
- a disengagement mechanism for disengaging said reversing mechanism, said disengagement mechanism comprising a biased member shaped and sized to disengage said trip shaft of said reversing mechanism when said biased member is depressed;
- wherein said biased member includes:
- a locking groove shaped to secure said trip shaft for rotation;
- and a biasing spring positioned to bias said locking groove against said trip shaft.
