  • Patent number: 8556193
    Abstract: A nozzle turret for an irrigation sprinkler includes a body having a rotational axis and a nozzle socket extending transverse to the rotational axis. A nozzle is removably received in the socket. A sleeve in the body opens on a top side of the body and defines a bore that communicates with the socket. A nozzle retention screw with a shank having a lower male threaded segment is screwed into the bore of the sleeve from the top side of the body. The shank extends into the socket a sufficient depth to retain the nozzle in the socket. The screw has a head that abuts an upper end of the sleeve when the screw is fully screwed in a downward direction into the sleeve. The screw shank has an upper unthreaded segment with a predetermined longitudinal dimension selected relative to a longitudinal dimension of the bore to enable the screw to be unscrewed in an upward direction from the sleeve despite stripping of a segment of a female threaded portion of the bore.

  • Patent number: 8528836
    Abstract: A leak stopping sprinkler head includes a hollow body that has an upper portion and a lower portion fluidly connected to a valve body. The upper portion has a spraying nozzle and a first internal diameter. The lower portion has a second, larger internal diameter. The valve body includes a valve seat fluidly connected to the lower portion and a water supply. A hollow spheroid is larger than the first diameter, smaller than the second diameter and has perforations for passage of water. A rigid rod connects the spheroid and a sealing disk for the valve seat. The rod is sized to hold the disk away from the valve seat when the hollow body is intact. Destruction of the hollow body permits the spheroid to move out of the hollow body, pulling the rod and the disk upwardly, causing the disk to seal the valve, stopping the flow of water.

  • Patent number: 8474733
    Abstract: A sprinkler includes a turbine, a nozzle, and a reversing planetary gear drive. The reversing planetary gear drive rotatably couples the turbine and the nozzle through an additional reversing mechanism external to the planetary gear drive. The planetary gear drive includes a shift sun gear capable of axially shifting between raised and lowered positions to alternately drive a non-axially shifting first planet gear that in turn drives a first ring gear and a non-axially shifting second planet gear that in turn drives a second ring gear through an idler gear, the first and second ring gears having different gear tooth profiles to thereby change a direction of rotation of the planetary gear drive and rotate the nozzle in clockwise and counter-clockwise directions at a substantially uniform predetermined speed of rotation.

  • Publication number: 20120273593
    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.
