Publication number: 20100038444Abstract: Many areas watered by prior art oscillating sprinklers are substantially rectangular. However, prior art oscillating sprinklers typically produce generally or substantially elliptical water distribution patterns. This geometric incompatibility causes problems and inefficiencies. Embodiments of the current invention include an oscillating sprinkler that automatically produces a substantially rectangular water distribution pattern. The substantially rectangular water distribution pattern may be produced by automatically controlling the distance from the sprinkler that streams of water travel before impacting the ground. This is accomplished by automatically and sequentially opening and closing and/or restricting flow to select nozzles at select points and within select portions of the oscillation cycle. A current invention oscillating sprinkler may reduce waste water, may reduce run-off waste water, and may automatically provide water to the corner areas of typical substantially rectangular areas to be watered.Type: ApplicationFiled: August 15, 2008Publication date: February 18, 2010Inventor: Eldon Coppersmith

Patent number: 7621464Abstract: A sprinkler having a water-driven drive mechanism or motor for rotating a sprinkler head is disclosed where the drive mechanism converts a constant input rate into a variable rate to reduce tailing from overly-rapid rotation and to promote full develop of water stream discharge profile. The drive mechanism includes continuously engaged members including one or more planet gears each having an offset or eccentrically positioned engagement portion for driving a second gear member. As the planet gear rotates, the movement of the engagement portion has a radial component relative to the second gear, and the rotational velocity of the second gear is related to the radial position of the engagement portion.Type: GrantFiled: December 14, 2006Date of Patent: November 24, 2009Assignee: Rain Bird CorporationInventors: Flynt Leroy Smith, Bandar Hussain Alumran, Mary Margaret Boice, Marianne Goble, Daniel S. Gabrys, Suzanne Lee Singer

Patent number: 7584906Abstract: An assembly for converting a fluid flow includes a housing having an inlet end for receiving the fluid flow and an outlet end for issuing a converted and output fluid flow. One or more rotatable components are supported within the housing, in a path contacting the inlet fluid flow. A selected component exhibits a plurality of arcuate and flow conducting surfaces, such as which are arranged about a circumference of the rotating component. A fluid dampening element is operatively connected to the rotating component and restricts a rotational speed associated with the rotatable component, in response to rotational forces imparted by the inlet fluid flow, and in order to modify at least one of a flow and pulse rate of the fluid.Type: GrantFiled: December 7, 2005Date of Patent: September 8, 2009Inventor: Mordechai Lev

Patent number: 7568635Abstract: A system and method is provided for atomizing a liquid without the use of air to atomize the liquid. The system comprises a turbo spray nozzle that has a rotatable shaft. The rotatable shaft has a center bore with an opening at one end to enable a liquid to flow into the center bore of the rotatable shaft. The rotatable shaft also has a plurality of orifices that extend from the center bore to an outer surface of the rotatable shaft at the end opposite the opening. The rotatable shaft is rotated by pressurized air. The rotation of the shaft causes the liquid flowing into the center bore to be induced into a helical flow path that causes the liquid to disassociate. The system may comprise a spray gun coupled to the turbo spray nozzle. The system may also comprise an air compressor to provide the pressurized air to rotate the rotatable shaft. The system may also comprise a container for the liquid hat may be pressurized to provide a motive force to the liquid.Type: GrantFiled: September 28, 2004Date of Patent: August 4, 2009Assignee: Illinois Tool Works Inc.Inventor: Paul R. Micheli

Patent number: 7566012Abstract: A multi-functional sprinkling apparatus structure comprises an outlet mount with support lugs to fix on top of a water motor, and a water-guiding member transversely mounted to assembly holes of the support lugs. The assembly holes have water ducts fluidly connected to water-inlet passages of the water-guiding member. A rotary member with a channel and a water shield with actuation holes are pivotally mounted to the middle section of the water-guiding member. The channel of the rotary member has multiple outlets with spray nozzles attached thereto to generate various sprays, and recesses to engage with a movable elastic element mounted to the water-guiding member. The rotary member can be switched to change the outlet matching to a water-discharge orifice of the water-guiding member for a certain spray. The water shield can be bent to one side to adjust the angle of the water-guiding member and the rotary member for sprinkling.Type: GrantFiled: March 8, 2007Date of Patent: July 28, 2009Assignee: Yuan Mei Corp.Inventors: King Yuan Wang, Shun Nan Lo

Patent number: 7484674Abstract: The present invention provides an improved water flow switching mechanism of a gear-type sprinkler, which addresses problems of typical gear-type sprinklers, such as invalid water switching and poor stability. The gear-type sprinkler includes a water inlet portion, a water outlet portion and accommodating space. A convex framework is additionally placed onto the accommodating space opposite the separate water outlets. Two lateral grooves are defined in the convex framework, each corresponding to a water outlet. So the pivotal portion of the rotary switching seat is assembled centrally into the convex framework. The rotary switching seat is provided with two opposite extension flanges. The extension flange may block the lateral groove of the convex framework in line with the swinging direction of the rotary switching seat. The water-stop area of rotary switching seat is greatly increased, thus ensuring the stability of the water flow switching state and improving performance of the sprinkler.Type: GrantFiled: September 18, 2007Date of Patent: February 3, 2009Inventor: Hsin-Fa Wang
