    Abstract: A sprinkler head includes a sprinkler body, a nozzle positioned within the sprinkler body, a fixed gear coupled with the sprinkler body, a wobbler cage supported on the sprinkler body, and a water deflector plate coupled with the wobbler cage and disposed downstream of the nozzle. A brake assembly is coupled with the water deflector plate for slowing a rotating and wobbling motion of the wobbler cage and the water deflector plate. The brake assembly includes a shaft extending through the water deflector plate and a brake gear disposed at an end of the shaft, where the brake gear is engageable with the fixed gear. Among other advantages, the design eliminates the use of large fixed strut framework that creates dry shadows in the water pattern.

    Abstract: A rigid mount orbiter sprinkler assembly incorporates a deflector plate configuration that is configured for both spinning/rotating motion as well as orbital or wobbling motion around the center of a spool assembly. The sprinkler incorporates structure to reduce drool that may fall in a concentrated area below the sprinkler and to prevent debris from sandy water or the like from accelerating sprinkler component wear. With reduced vibration, the assembly may be rigidly mounted on a center pivot or other supporting structure while achieving the advantages associated with wobbling and rotating sprinkler assemblies.

    Abstract: A sprinkler assembly includes a sprinkler body with a water flow passage connected to a water source. The sprinkler body includes a recess. A nozzle insert is received in the recess and is positionable in the recess in multiple positions. The nozzle insert includes a nozzle bore extending therethrough and alignable with the water flow passage in at least one of the multiple positions. The nozzle insert may also include a handle with an opening therein. A nozzle clip has a proximal end securable in the handle opening, and in one embodiment, a spare nozzle is secured to a distal end of the nozzle clip. In some versions, a spring insert supports a spring in the recess.

    Abstract: A sprinkler and side-loading nozzle insert assembly includes, in a preferred arrangement, a sprinkler body provided with a flow passage along a sprinkler body axis and a nozzle insert spring-loaded received in a complementary recess formed in the sprinkler body. The nozzle insert has an axis of rotation transverse to the sprinkler body axis and is rotatable from an insertion position to plural operating positions. The nozzle insert is provided with an elongated, substantially cylindrical insert body including a nozzle bore extending through the insert body on an axis transverse to the axis of rotation and alignable with the flow passage in at least two of the plural operating positions. Plural index tabs extend radially from the insert body at circumferentially-spaced locations, and are adapted to engage respective plural index notches in the sprinkler body as the insert body is rotated to the plural operating positions.

    Abstract: A rotational speed control device includes a housing containing a viscous fluid, a shaft disposed in the housing and rotatable relative to the housing, a hub assembly secured to the shaft for rotation with the shaft, and a rotor coupled with the shaft by a frictional engagement with the hub assembly. A spring is disposed in the housing and acts on the rotor to bias the rotor axially on the shaft in a low torque direction. A braking torque between the rotor and the housing is varied according to an axial position of the rotor on the shaft.

    Abstract: An automatic reversible arc assembly for a sprinkler includes a pair of primary stop members circumferentially spaced from each other by a first amount, and a pair of secondary stop members circumferentially spaced from each other by a second amount, different from the first amount. The primary stop members and the secondary stop members are coupled together and define a pivot assembly pivotable between a first position and a second position. A timer module cooperable with the pivot assembly is configured to hold the pivot assembly in the first position for a selectable period of time, after which the timer module enables the pivot assembly to pivot to the second position. The primary stop members are active in the first position, and the secondary stop members are active in the second position.
