Abstract: A sprinkler includes a turbine, a nozzle, a gear train reduction and a reversing mechanism that rotatably couples the gear train reduction and the nozzle. The gear train reduction includes an input stage and a planetary gear drive output stage that includes a first portion of the reversing mechanism. A second portion of the reversing mechanism is located outside of the gear train reduction. The second portion of the reversing mechanism includes a pair of arc tabs. At least one of the arc tabs is adjustable to establish an arc of coverage of the sprinkler when the water flowing past the turbine causes the gear train reduction and the reversing mechanism to oscillate the nozzle back and forth between a pair of arc stops. The arc stops are defined by the locations of the arc tabs. The input stage of the gear train reduction includes a mechanism that allows manual rotation of the nozzle between the arc stops without having to back drive the gears in the input stage.

Abstract: A rotary sprinkler having an adjustable arc segment whose angular extent and absolute direction relative to the ground are represented by an arc indicator, which arc indicator may comprise a band whose visible length represents the angular extent and whose position on the sprinkler points to the direction. The sprinkler may have the arc segment adjusted by a movable arc limit stop that is coupled to a toggle member only at drive reversal, and the sprinkler may be converted to full circle operation by raising the arc limit stop relative to a cooperating trip tab. A buckling spring assembly used to shift the drive comprises a compression spring held between two spaced pivot members, and the drive can be built in continuous and intermittent drive versions by replacing a few normal rotary gears with multilated gears. A friction clutch having asymmetric teeth for smooth operation prevents damage to the drive during forced nozzle rotation.

Abstract: A recessed incrementally rotating nozzle assembly is located in a wall or bottom surface of a swimming pool in fluid communication through a conduit with a source of water under pressure from a valve, which valve periodically releases water into the conduit. Each time water flows, a nozzle housing is raised to eject a stream of water. As the nozzle housing rises, it is incrementally rotated by a pin engaging a saw tooth member of a cam ring. Upon cessation of flow, the nozzle housing is retracted and during retraction the nozzle housing is further incrementally rotated by the pin engaging another saw tooth member of the cam ring. After a predetermined degree of angular rotation, a cam reverser slidably reorients protrusions guiding the pin into and out of the saw tooth members to cause the pin to be guided by the opposite side of the saw tooth members and thereby cause reversal of the direction of rotation of the nozzle housing.

Abstract: A speed limiting mechanisms for turbine-driven fluid distribution apparatus usable with compressible fluid such as compressed air and incompressible fluid such as water. Dynamic viscous damping of the turbine output power train is used to control the rotational speed of the turbine. This prevents overspeeding when the turbine is air driven, and also when the turbine is water driven, under abnormal conditions such as blockage of a bypass area designed to control the turbine speed by limiting flow to the turbine. The same mechanism can be used to impose a lower rotational speed in the turbine during normal operation in conjunction with a turbine optimized for lower speed operation to reduce the required gear reduction in the power train.

Abstract: An improved rotary drive sprinkler is provided for rotatably driving a pop-up spray head in a stepwise manner through a full-circle or reversibly within a selected part-circle path. The sprinkler includes a reversing trip mechanism having a pair of spaced-apart stops rotatable with the spray head and defining preset end limits of a part-circle path, wherein a stationary trip wire is engageable with the stops to switch an internal rotary drive assembly, such as a ball drive assembly, between forward- and reverse-drive operation.

Alternatively, the stops can be set in side-by-side relation with their ramped surfaces oriented for the trip wire to ride resiliently thereover without switching of the rotary drive assembly.

Abstract: A rotating stream sprinkler is provided with an improved spray head for sweeping one or more outwardly projected water streams through a prescribed arcuate spray path, wherein the spray head is adapted for enhanced self-flushing operation to prevent accumulation of grit and the like which could otherwise impair sprinkler performance. In the preferred form, the spray head is mounted at the upper end of a pop-up stem for movement to an elevated spraying position upon supply of water under pressure to the sprinkler. The water flows to the spray head and normally pressure-loads a plurality of valve balls onto a respective plurality of seats to prevent water flow through the seats to associated nozzle passages. A drive assembly rotates the spray head relative to a nonrotating cam positioned to lift one or more of the valve balls from their respective seats to permit outward discharge of one or more water streams through the nozzle passages, within the limits of the prescribed arcuate path.

Abstract: A rotating stream nozzle is provided particularly for use as an irrigation sprinkler, wherein the nozzle provides a plurality of outwardly directed and discrete water streams which are rotated in steps through a prescribed arcuate spray path. The rotating stream nozzle is adapted for mounting onto a water supply conduit and includes a swirl plate through which water under pressure flows with a swirling action into a relatively small drive chamber. The swirling water flow forces a drive ball within the drive chamber to move into repetitious impact engagement with raised anvils formed on the inner diameter surface of a cylindrical rotor lining the drive chamber and mounted for rotation within a nozzle cap. The rotor is displaced through a small rotational step each time the drive ball strikes one of the anvils, and the water is discharged from the nozzle as discrete rotating streams passing through small discharge ports in the rotor.

The nozzle may be interchanged with other nozzles to provide matched precipitation rates for sectors of different sizes. The feature of incremental rotation of the nozzle overcomes the problem of reduced throw distance at high rotational speeds encountered by the prior art assemblies of the same general type.

Abstract: An improved rotary drive sprinkler is provided for rotatably driving a pop-up spray head in a stepwise manner through a full-circle or reversibly within a selected part-circle path. The sprinkler includes a reversing trip mechanism having a pair of spaced-apart stops rotatable with the spray head and defining preset end limits of a part-circle path, wherein a stationary trip wire is engageable with the stops to switch an internal rotary drive assembly, such as a ball drive assembly, between forward- and reverse-drive operation. The trip wire flexes to accommodate forced spray head rotation to a maladjusted position beyond the end limits and, upon subsequent sprinkler operation, rides over ramped surfaces on the stops for automatic return to reversible operation between the reset end limits. Alternatively, the stops can be set in side-by-side relation with their ramped surfaces oriented for the trip wire to ride resiliently thereover without switching of the rotary drive assembly.
