A clip for holding a pair of nozzle inserts for use with an irrigation sprinkler includes at least two flexible attachment arms, each attachment arm provided with an elongated slot and a retention shoulder on an inside surface thereof, adjacent the elongated slot. Each attachment arm is adapted to be received in an opening in a respective nozzle insert and retained therein by the retention shoulder. A related tool includes a pair of gripper arms and a respective pair of jaws extending from the gripper arms, pivotally secured to one another. One jaw is formed with a pair of parallel prongs, and the other jaw is formed with a flat head projecting toward the pair of prongs. The jaws are adapted to engage the nozzle insert and disengage the retention shoulder to permit removal of the nozzle insert from the clip.

Sprinkler with multi-functional, side-load nozzle with nozzle storage clip and related tool

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.

Sprinkler with multi-functional, side-load nozzle

A sprinkler and side-loading nozzle insert assembly includes a sprinkler body provided with a flow passage and a nozzle insert seated in a complementary recess in said sprinkler body. The nozzle insert is rotatable to plural operating positions and it includes an elongated, substantially cylindrical insert body having an insert axis about which the nozzle insert rotates. A nozzle bore extends through the insert body on an axis transverse to the insert axis and alignable with the flow passage in one of the plural operating positions. A forward end face is provided with a turning knob and plural index tabs extending radially from the insert body at circumferentially-spaced locations proximate the forward end face. The index tabs are adapted to engage respective index notches in the sprinkler body as the insert body is rotated to the plural operating positions.

The present invention relates to a rotary pop-up type sprinkler device which includes a stationary nozzle for issuing a stream of water which engages a rotary distributor. The device includes a first outer housing designed for in-ground installation, and a second inner housing telescopically mounted within the outer housing. Upon commencement of flow of water under pressure into the sprinkler device, the second inner housing is extended to an above ground or operative position. The second inner housing is normally spring biased to the below ground inoperative position so that, upon cessation of the supply of water under pressure, the second inner housing returns automatically to its below ground inoperative position within the first outer housing. The second inner housing is also provided with a nozzle disk including at least one discharge orifice for discharging the stream of water under pressure. The second inner housing also mounts a speed reducing assembly for slowing the rotational speed of the distributor. The speed reducing assembly includes a shaft which supports the rotary distributor at one end thereof downstream of the discharge orifice. The other end of the shaft is received within a speed reducing assembly housing located upstream of the discharge orifice. A flow path is established which isolates both the shaft and substantially all of the brake assembly housing from contact with water under pressure upstream of the discharge orifice.
