The sprinkler includes a nozzle body and a valve sleeve that helically engage each other to define an arcuate slot that may be adjusted at the top of the sprinkler to a desired arcuate span. The sprinkler may include a flow rate adjustment device that may be adjusted by actuation or rotation of an outer wall portion of the sprinkler. Rotation of the outer wall portion may cause a throttle control member to move axially to or away from an inlet, or may cause one or more restrictor elements to open or close, to control the flow rate of the sprinkler.Type: ApplicationFiled: November 21, 2011Publication date: March 15, 2012Applicant: RAIN BIRD CORPORATIONInventors: Steven Brian Hunnicutt, Samuel C.

Patent number: 8028932Abstract: A rotary, nutating sprinkler head includes a housing supporting a nozzle; a starter tube axially adjacent the nozzle and extending in a downstream direction, concentric with a vertical center axis of the sprinkler head. A spool assembly is loosely supported on the starter tube, the spool assembly including a double-flanged spool and a water-deflection plate carried by the spool, the water-deflection plate formed with one or more grooves shaped to cause the spool assembly to rotate when impinged upon by a stream emitted from the nozzle. Either the starter tube or the spool is provided with at least one tilting lug located to keep the spool assembly in a tilted or angularly offset orientation relative to the vertical center axis, thereby facilitating a wobbling action of the spool assembly during rotation.Type: GrantFiled: April 1, 2009Date of Patent: October 4, 2011Assignee: Nelson Irrigation CorporationInventors: George L. Sesser, Craig B. Nelson

Patent number: 8006919Abstract: In a preferred embodiment of the present invention a sprinkler is provided, having a first shaft coupled to a drive mechanism and a grooved deflector. A second shaft is disposed within the first shaft, coupled to a water flow adjustment mechanism and an adjustment region on the top of the deflector. The first shaft transfers rotational movement from the drive mechanism to a grooved deflector on the top of the sprinkler. The second shaft rotates with the first shaft during normal operation due to a friction clutch within the sprinkler. When the user desires to adjust the water flow (i.e., the radius of the water), the friction of the clutch can be overcome by rotating the second shaft, increasing openings of flow passages within the sprinkler body. In this respect, flow adjustments can be made from the top of the sprinkler while the deflector rotates.Type: GrantFiled: September 12, 2008Date of Patent: August 30, 2011Assignee: The Toro CompanyInventors: Steven C. Renquist, Peter Janku, Richard C. McClure, Saroj Manandhar

Patent number: 7954731Abstract: A rotary impact sprinkler is disclosed having a nozzle connected to a housing and a discharge deflector member connected to a rotatable shaft assembly without a dynamic seal between the nozzle and the deflector. The sprinkler may be provided with different nozzles and discharge deflectors that are easily removed and replaced for providing desired water flow and discharge characteristics. The shaft assembly and housing may have contacting braking surfaces outside of the water flow. The braking surfaces may provide a frictional braking force dependent on both water flow rate and water flow pressure. The sprinkler has a rotatable impact assembly supported by the shaft assembly and including a deflection member for rotating the impact assembly relative to the shaft assembly. The shaft assembly may have a pin for supporting the impact assembly at a position above the deflection member.Type: GrantFiled: June 4, 2004Date of Patent: June 7, 2011Assignee: Rain Bird CorporationInventors: Thomas A. Antonucci, Brian W. Lees, Valery A. Monge, Kelly F. Olischefski, Michael F. Turk, Keith E. Turner, Richard J. Russell, II

Publication number: 20110121097Abstract: A variable arc sprinkler head or nozzle may be set to numerous positions to adjust the arcuate span of the sprinkler. The sprinkler head includes an arc adjustment valve having two portions that helically engage each other to define an opening that may be adjusted at the top of the sprinkler to a desired arcuate length. The arcuate length may be adjusted by pressing down and rotating a deflector to directly actuate the valve. The sprinkler head may include a lock-out feature to prevent adjustment. A method of irrigation is also provided involving moving the deflector between an arc adjustment position and an operational, irrigation position. The sprinkler head may also include a flow rate adjustment valve that may be adjusted by actuation of an outer wall of the sprinkler. Rotation of the outer wall causes a flow control member to move axially to or away from an inlet.Type: ApplicationFiled: November 23, 2010Publication date: May 26, 2011Inventors: Samuel C. Walker, Steven Brian Hunnicutt

Publication number: 20110031325Abstract: A rotary sprinkler includes a housing supporting a nozzle and a nozzle tube, the nozzle tube located axially adjacent an orifice of the nozzle with an axial gap therebetween. A water-deflection plate assembly is carried by the nozzle tube for rotation relative to the nozzle tube. The housing is formed with an exterior substantially annular funnel surrounding the nozzle and forming a collection trough for collection of excess water, and the housing formed with one or more apertures directing excess water in the collection trough to an internal area surrounding the orifice to be aspirated through the gap into a stream of water emitted from the nozzle orifice and through the nozzle tube such that the excess water is distributed by the water-deflection plate along with water emitted from the nozzle orifice.Type: ApplicationFiled: August 7, 2009Publication date: February 10, 2011Applicant: Nelson Irrigation CorporationInventors: Lee A.
