Patent number: 7261247Abstract: A slip-clutch assembly including a slip gear and clutch for a sprinkler motor of a sprinkler is disclosed for reducing damage to movable portions of the sprinkler is disclosed. The slip-clutch assembly allows at least a portion of a motor assembly or a sprinkler head to rotate at a rate lower than under normal operating conditions. The slip-clutch assembly includes a first component or portion with deformable portions received under normal operating conditions within recesses or cooperating structure of a second component or portion. The deformable portions are able to release or slip from the cooperating structure when the rotation of a portion of the sprinkler is impeded by a force exceeding a predetermined level.

Patent number: 7090146Abstract: An above-ground sprinkler may have a head that rotates about an angle determined by the relative angles between a pair of arc adjustment rings. Rotation of the head may be driven by a drive mechanism with a rotor rotationally driven by fluid flowing to the head. The drive mechanism may have a valve disposable in two positions to control flow to the rotor to determine the direction in which the rotor rotates. A reduction gear drive may transmit torque from the rotor to the head to cause the head to rotate. The head may have a cover with an outlet aperture and a flow control member that rotates within the cover to dispose any of a plurality of nozzles in alignment with the outlet aperture. A deflection screw or a slider with a plurality of deflectors may be used to provide variable deflection of water sprayed from the outlet aperture.Type: GrantFiled: March 23, 2004Date of Patent: August 15, 2006Assignee: Orbit Irrigation Products, Inc.Inventors: Kent C. Ericksen, Alan John Smith

Publication number: 20040261438Abstract: Method for making snow wherein snow is made within a closed environment by discharging water droplets into a body of air maintained by air conditioning means at a temperature and humidity such as to turn the water droplets into snow, falling on to a surface including coolant pipes which are covered with a layer of snow, the coolant being at a lower temperature than the air temperature such that there is a temperature gradient in the snow layer of the order of 0.1 degrees centigrade per centimetre depth, whereby during the initial part of the process a small quantity of small droplets is discharged to provide nucleating particles, and thereafter a larger quantity of droplets is discharged and whereby incoming air to be discharged into the body of air is drawn over cold surfaces.Type: ApplicationFiled: June 4, 2004Publication date: December 30, 2004Inventors: Malcolm George Clulow, David Winnett

Patent number: 6705548Abstract: A nozzle for spraying surfaces is equipped with a piston rod centrally arranged in a feeding duct. The piston rod has an impact plate which is held by a spring in a position aligned with the surface to be sprayed. As a result of liquid pressure, the impact plate arrives in a second end position at a distance from the surface to be sprayed in which. As a result of a ring gap on an input side around the piston rod, the impact plate becomes a deflecting part for the spraying liquid exiting in a ring shape, which, in a circular spraying cone directed at a flat angle with respect to the surface to be sprayed, is then emitted onto the surface to be sprayed.Type: GrantFiled: July 9, 2001Date of Patent: March 16, 2004Assignee: Lechler GmbH & Co. KGInventors: Lothar Bendig, Hermann Lange

Patent number: 6629648Abstract: An adjustable riser for adjusting the elevational position of an irrigation sprinkler with respect to the surrounding ground level and/or with respect to the height of surrounding vegetation to be irrigated. The riser includes a movable cartridge within an internal bore of a housing having a plurality of catches outwardly projecting from the exterior wall of the cartridge and adapted to resiliently snap into or out of notches carried on the inner wall surface of the bore movably supporting the cartridge. The sprinkler is carried on a tube for discharging water while the opposite end of the tube includes an impact plate against which water pressure from the supply impinges. Upon impact, the tube with the sprinkler is forced upward within a housing against expansion of a spring, which normally urges the tube and sprinkler into a storage position within the housing.Type: GrantFiled: February 14, 2003Date of Patent: October 7, 2003Inventor: Steven Jones

Patent number: 6135362Abstract: A riser assembly for an irrigation system, including a first riser segment attached to a supply line and a second riser segment attached to the first riser segment at a first end and to a sprinkler at the second end. The riser assembly also includes a control valve which may be inserted between the second riser segment and a sprinkler gun. The various segments and the control valve and sprinkler are all coupled employing mechanical couplings which permit a degree of flexion at the coupling or joint. The first riser segment is formed of a section of PVC pipe and the second riser section is formed of a segment of copper alloy pipe.Type: GrantFiled: October 27, 1999Date of Patent: October 24, 2000Inventor: Nicholas R.

Patent number: 6082638Abstract: The present invention provides a machine that applies chemical anti-icing agents to any surface to be protected from snow and ice, i.e., driveways, walkways, rooftops, etc. More specifically, the device is affixed to stationary surfaces and permits adjustment to spray nozzles. Thus liquid chemical anti-icing agents are applied to the target surfaces by spraying the liquid in a manner intended to prevent snow and ice from forming a bond with the target surface. The device permits the permanent installation of spray nozzles on, in or near the surface intended to be protected by anti-icing agents. The device is easily maintained and left in a state of preparedness for use in the event of icing conditions. The invention provides a durable, adjustable and permanent point of attachment for spray nozzles for anti-icing purposes. The device may be surface mounted or embedded in an existing structure. Use of the device greatly increases the margin of safety for users of the driveways, sidewalks, etc.Type: GrantFiled: June 3, 1998Date of Patent: July 4, 2000Assignee: Odin Systems International, Inc.Inventors: Bernard J.
