Abstract: A combined nozzle set and lift tool is provided for use with a pop-up sprinkler, wherein the lift tool comprises a tool body in the form of an injection molded runner formed integrally with a plurality of individual nozzle inserts. An elongated tool stem projects outwardly from the tool body and has protruding tabs at a tip end thereof for reception into an undercut recess formed in a pop-up sprinkler spray head to permit lifting of the spray head from a normal position spring-retracted substantially within a sprinkler housing or case, to an elevated position for facilitated access to the spray head. A selected one of the plurality of nozzle inserts can be separated from the lift tool as by snap-off detachment, whereupon the selected nozzle insert can be mounted on the elevated spray head to individually tailor the characteristics of a water stream projected therefrom during normal sprinkler operation. The lift tool further includes latch teeth for snap-fit engagement with the spray head to permit storage of the combined nozzle set and lift tool on the spray head, to provide a convenient commercial unit which can be transported to an installation site with little or no risk of components becoming lost or misplaced.

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. In a preferred construction, the drive assembly includes a rotatable turbine driven by water inflow to the sprinkler and further includes drive balls for rotating the spray head in a stepwise manner. The turbine is also designed for improved operational reliability particularly when used with water having a significant amount of grit particles therein.

Abstract: A variable arc sprinkler may be set to numerous positions along a continuum to adjust the arcuate span of the sprinkler. The sprinkler includes a nozzle body and a valve sleeve that helically engage each other to define an arcuate slot that may be adjusted at the top of the sprinkler to a desired arcuate span. The sprinkler may include a flow rate adjustment device that may be adjusted by actuation or rotation of an outer wall portion of the sprinkler. Rotation of the outer wall portion may cause a throttle control member to move axially to or away from an inlet, or may cause one or more restrictor elements to open or close, to control the flow rate of the sprinkler.

Abstract: A specialty nozzle is provided having a pattern adjustment valve that may be adjusted to irrigate a substantially rectangular irrigation area. The nozzle may be further adjusted to irrigate two different substantially rectangular irrigation areas. The nozzle functions as a three-in-one left strip nozzle, right strip nozzle, and side strip nozzle. The arcuate length may be adjusted by pressing down and rotating a deflector to directly actuate the valve. The nozzle may also include a radius adjustment valve that may be adjusted by actuation of an outer wall of the nozzle. Rotation of the outer wall causes a flow control member to move axially to or away from an inlet.

Abstract: A down flow spray nozzle is provided in which water is directed downwardly against one or more deflector surfaces for improved water distribution to terrain near to and distant from the nozzle. The nozzle is mounted to a water source and may include a nozzle base and a nozzle body having flow passages. Water flows upwardly into the flow passages of the nozzle base, upwardly through flow passages in the nozzle body into a chamber, and is redirected downwardly through other flow passages in the nozzle body. The water is directed downwardly against concave deflector surfaces in the nozzle base and outwardly to surrounding terrain.

Abstract: An improved rotating stream sprinkler of the type having a rotatable spray head with an offset nozzle port through which a water stream is projected outwardly, resulting in a reaction force for rotatably driving the spray head to sweep the water stream over a surrounding terrain area. The spray head is rotatably mounted on a body adapted for connection to a pressurized water supply, with interengaging bearing components providing predetermined friction brake torque resisting spray head rotation. By appropriately designing the nozzle port area and offset geometry, drive torque and brake torque is maintained at a substantially constant ratio for relatively slow and substantially constant spray head rotational speed over a range of normal water supply operating pressures. A downthrust spring retains the bearing components in engagement when the water supply is turned off, but does not contribute to friction brake torque when the water supply is turned on.
