Abstract:
An irrigation sprinkler includes a riser and a nozzle turret rotatably mounted at an upper end of the riser. A drive assembly is mounted in the riser and is coupled to the nozzle turret for rotating the nozzle turret. The drive assembly includes a reversing mechanism having a pair of arc tabs. A position of one of the arc tabs is adjustable through an adjustable arc setting mechanism to change a size of an angle through which the nozzle turret oscillates to thereby pre-set an arc of coverage of the sprinkler. The adjustable arc setting mechanism includes a first portion that is manually movable to effectuate a coarse adjustment of the position of the adjustable arc tab and a second portion that is manually movable to effectuate a fine adjustment of the position of the adjustable arc tab.
Abstract:
In order to protect the operation of and insure the life of a sprinkler system, this device will be placed in the ground and will provide a protective cover for an individual sprinkler mechanism. The device will prevent the entry of debris into the sprinkler mechanism but also not interfere with the normal operation of the sprinkler. Additionally this will also allow the performance of routine maintenance on the sprinkler heads without the necessity of removing the entire sprinkler assembly.
Abstract:
A cone valve assembly including an upper valve member with a conical top portion and a stepped and spiraled top surface and a lower valve member including a central opening with a stepped and spiraled valve surface surrounding the central opening. The upper valve member is mounted in the lower valve member such that the lower valve member is rotatable and axially movable relative to the upper valve member. Rotation of the lower valve member allows for the adjustment of an arcuate slot opening that provides a conically shaped discharge stream of water from the cone valve nozzle assembly directly onto the rotating distributor to provide the desired arc of sprinkler coverage.
Abstract:
An irrigation sprinkler is provided having a nozzle and a turret for the distribution of irrigation water that includes a latching portion so that the nozzle may be detachably inserted into a nozzle socket of the turret. The nozzle may include radially flexible extensions with radial protrusions that interengage with corresponding lock seats of the nozzle socket to form a latching connection therewith. The latching connection restricts the nozzle from becoming unintentionally discharged from the nozzle socket. The nozzle may further be configured so that increased water pressure acting on the nozzle causes the radial protrusions to more tightly engage the nozzle socket to prevent unintentional discharge of the nozzle.
Abstract:
The present invention includes an improved sprinkler design having a magnetic sensing system for determining the position of the riser nozzle, a waterproofed motor housing and related cables, configurable sprinkler body compartments, and a pilot valve with a check valve assembly, both of which are located within the sprinkler body.

Abstract:
An irrigation sprinkler has a riser assembly that includes a rotatably mounted nozzle turret, a secondary nozzle holder removably mounted on the nozzle turret, and a turbine. A drive assembly is mounted in the riser assembly and couples the turbine and the nozzle turret so that pressurized water entering a lower end of the riser assembly will cause the nozzle turret to rotate. The nozzle turret has a primary nozzle and the secondary nozzle holder has at least one secondary nozzle.
Abstract:
Disclosed is a valve for use in in-floor pool cleaning systems. The valve has a housing with an inlet port, an internal cavity and multiple outlet ports. A drive source, which can be an impeller positioned in the cavity and in fluid communication with the inlet port, is directly or indirectly (such as by a gear assembly) connected to a fluid control plate that has one or more apertures. As fluid enters the cavity through the inlet port the drive rotates the fluid control plate. As the plate rotates the aperture(s) rotate to allow the fluid to pass through the aperture(s) and into the respective outlet ports.
Abstract:
An in-ground shrouded sprinkler assembly is provided, including: a sprinkler assembly which includes an upright riser on which a sprinkler head is mounted; a shroud which includes one or more wads with an opening at the top thereof, wherein the wall(s) substantially surround a sprinkler assembly, but wherein the wall(s) do not surround the sprinkler head in a manner which will, in use, interfere with delivery of liquid via the sprinkler head; and wherein the shroud is configured to include: an above ground portion; and a below ground engaging portion; wherein the shroud also includes an animal guard which covers the opening and protects the sprinkler assembly.
Abstract:
A sprinkler support for the in-ground sprinkler heads includes a base at the lower position, a sidewall extending vertically ascending from the base, a clamping structure disposed at the sidewall of the sprinkler support to secure the sprinkler head, a cushioning structure capable to absorb physical stresses, and anchoring structures holding the sprinkler support with respect to the soil. The sprinkler support accommodates a variety of different size of sprinkler heads by having an adapter, by cantilever fingers extended from the sidewall upwardly or by constructing with two halves, wherein each half comprises the base and sidewall.
