摘要： 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. A nozzle assembly includes a pivotal nozzle that carries a radius adjustment screw with the head of the screw received on top a flexible portion of a top cover, which top cover has laser etched indicia relating to various adjustments of the sprinkler. A flow shut off valve includes stream straightening vanes and a collar may be used to support the sprinkler on a stake or post for above ground installation.

摘要： A planetary gear drive assembly for a rotary sprinkler includes a drive housing in which a planetary gear train is enclosed. A turbine located beneath one end of the drive housing rotates the gear train through a turbine shaft that extends into the drive housing. An output shaft extends out of the other end of the drive housing for rotating the nozzle assembly of the rotary sprinkler. The drive assembly includes an alignment means for causing the planetary gears in each stage of the gear train to self align the planetary gears relative to an internal ring gear on the drive housing as each stage is slid into the drive housing during assembly. The alignment means comprises a stepped extension on a forward edge of the ring gear that extends around only a portion of the circumference of the ring gear.

摘要： An improved sprinkler comprises a nozzle body having a nozzle received in a recessed seat provided in a peripheral wall of the nozzle body. The nozzle body has a rotatable upper cover. A cam surface is formed on the cover and extends down into engagement with the nozzle. The cam surface is shaped to push the nozzle at least partially out of its seat during rotation of the cover to allow the user to be able to grip the nozzle and complete its removal by pulling outwardly on the nozzle. The cover also includes a locking rib which can be brought to bear against the nozzle when the nozzle is fully received in its seat to help retain the nozzle in place. Desirably, the cover also includes a radius adjustment screw which is located in front of and spaced away from the front end of the nozzle such that the screw does not in any way engage or bear against the nozzle to prevent damage to the nozzle from the screw.

摘要： An improved sprinkler nozzle comprises a nozzle body having a nozzle received in a recessed seat provided in a peripheral wall of the nozzle body. The nozzle is formed with a plurality of nozzle ports formed by the radially outer ends of a plurality of vertically flexible nozzle tubes. The flow volume of the water stream being thrown by the sprinkler nozzle is adjusted by selectively operating a flow volume adjustment member carried on the nozzle body to selectively open or close various of the nozzle tubes in various possible combinations. The flow volume of the nozzle will comprise the combined or aggregate flow volumes of the water sub-streams being thrown by those nozzle tubes that are left open. The trajectory of the water stream being thrown by the sprinkler nozzle is adjusted by selectively operating a trajectory adjustment member carried on the nozzle body to bend the flexible nozzle tubes about their vertically fixed, radial inner ends to raise and lower the radial outer ends of the nozzle tubes.

摘要： A fixed spray sprinkler nozzle has adjustable arc coverage. The nozzle has a nozzle body with sideward facing water discharge slots including a bottom slot and a top slot. Flow blocking skirts control the open length of each of the slots. The bottom slot is fixed on the nozzle body, but the top slot is rotatable on the nozzle body, in concert with the opening or unblocking of the bottom slot's length, from a position overlying the bottom slot to a position directed in an opposite direction from the bottom slot. When the bottom slot is fully open, the top slot may then be progressively opened over its entire length. Thus, the arc coverage can be infinitely adjusted over the combined circumferential length of both the bottom and top slots together. The slots have a grooved bottom wall to provide smooth water flow and good pattern definition at each side of the selected arc.

摘要： A gear drive assembly for a rotary sprinkler includes a drive housing in which a reduction gear train is enclosed. A turbine located beneath one end of the drive housing rotates the gear train through a turbine shaft that extends into the drive housing. An output shaft extends out of the other end of the drive housing for rotating the nozzle assembly of the rotary sprinkler. The drive assembly includes a relatively large water entry port which is screened by a filter screen having relatively small openings. The water entry port allow enough water to enter the drive housing upon initial pressurization of the sprinkler such that sand particles suspended in the water do not jam the output shaft or the turbine shaft. The openings in the filter screen prevent the entry of particles into the drive housing that would tend to jam or foul the reduction gear train.
