Abstract: A rotary nozzle sprinkler includes a base assembly with a bearing, a stem mounted rotatably in the bearing, and an elbow coupled at a proximal end to and rotatable with the stem and including an elbow bend. A nozzle is secured to a distal end of the elbow, and a diffuser assembly including a brake mechanism is cooperable with the elbow. By positioning the nozzle downstream of the elbow, the sprinkler can achieve a greater throw radius.

Abstract: A rigid mount orbitor 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 includes a spider ingress opening cooperable with a spider barrier that in combination permit inevitable spider ingress while preventing spider access or contact with certain moving parts of the sprinkler.

Abstract: A rotational speed control device maintains a shaft rotation speed. The device includes a housing containing a viscous fluid and a shaft disposed in the housing and rotatable relative to the housing. A rotor is coupled with the shaft for rotation in the viscous fluid. The rotor is axially displaceable along the shaft between a low-shear position and a high-shear position. A spring mechanism is disposed in the housing and biases the rotor toward the low-shear position. The rotor may be designed to cooperate with the housing or other nonrotating features within the housing to vary a shear gap according to the axial position of the rotor. The rotor, housing and spring mechanism can be designed to cooperate to create large changes in braking torque in response to small changes in shaft rotational speed. This allows the rotation speed to be controlled within a relatively narrow range.

Abstract: A sprinkler head includes a sprinkler body having an inlet bore at one end, and a coupling element at an opposite end adapted to connect the sprinkler body to a water deflector plate. A multi-nozzle shuttle supports at least two nozzles and is attached to the sprinkler body axially between the inlet bore and the coupling element for swinging pivotal movement between two nozzle-installed positions. The multi-nozzle shuttle may also be provided with a shut-off surface portion for shutting off flow through the sprinkler body when the multi-nozzle shuttle is moved to a shut-off position. The shuttle may be moved manually or by a power actuator.

Abstract: A rigid mount orbitor 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 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 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.
