Hold-Up Tool For Pop-Up Sprinkler Risers

US Patent:
D502986, Mar 15, 2005
Filed:
Dec 12, 2003
Appl. No.:
29/195645
Inventors:
Ravi K. Bandlamuri - Tucson AZ, US
Derek M. Nations - Tucson AZ, US
Assignee:
Rain Bird Corporation - Glendora CA
International Classification:
2301
US Classification:
D23214, D23217, D23218

Gear Drive Sprinkler

US Patent:
20020092924, Jul 18, 2002
Filed:
Jan 15, 2002
Appl. No.:
10/053532
Inventors:
John Ingham - Tucson AZ, US
Jerry Lawyer - Benson AZ, US
Charles Lemme - Tucson AZ, US
Michael McAfee - Tucson AZ, US
Derek Nations - Tucson AZ, US
Matthew Prucinsky - Irvine CA, US
David Steimle - Tucson AZ, US
International Classification:
B05B003/04
US Classification:
239/205000, 239/240000
Abstract:
An improved gear drive sprinkler has a pop-up spray head adapted for adjustable part-circle or full circle operation to deliver irrigation water over a selected terrain area. The sprinkler includes a pop-up riser having a rotatable spray head mounted at an upper end thereof. A gear drive transmission mounted within the riser includes a water-driven turbine for rotatably driving a speed reduction gear train which in turn rotatably drives the spray head. A reverse assembly includes an upper trip unit defining an individually adjustable pair of end trip stops, and a lower shift mechanism including a shiftable director plate having first and second sets of angularly oriented jet nozzles for respective alignment with turbine jet ports for respectively driving the water-driven turbine and the gear train in a forward-drive or a reverse-drive direction. The upper trip unit is coupled to the director plate by an elongated trip rod which shifts the director plate between forward-drive and reverse-drive positions in response to spray head rotation to a position corresponding with one of the end trip stops. An adjustment cam can be manipulated to disable at least one of the end trip stops to permit spray head rotation through continuous full circle revolutions. The upper trip unit additionally includes a spring-loaded clutch adapted to disengage in response to attempted forced rotation of the spray head, to prevent vandalism damage to reverse assembly components.

Rotary Irrigation Sprinkler With A Turret Mounted Drive System

US Patent:
20110017842, Jan 27, 2011
Filed:
Jun 30, 2010
Appl. No.:

Kenneth John Skripkar - Tucson AZ, US
Steve Craig Haeske - Allendale MI, US
International Classification:
B05B 3/06
US Classification:
239251
Abstract:
Disclosed are rotary sprinklers having a turret mounted drive system. In one aspect, the complete drive mechanism, including all components thereof, is positioned in the rotary turret portion of the rotary sprinkler. In another aspect, the turret mounted drive system includes a main drive element, such as a turbine, paddle wheel, or the like, positioned adjacent a flow passage or nozzle outlet and oriented to be driven from a fluid flow projected from the sprinkler. In yet another aspect, the turret mounted drive system also has associated gearing assemblies, which may include appropriate gear reduction modules, also mounted within the turret, but outside of the fluid flow path.
