The Rain Bird horizontal action impact drive sprinkler head was invented in 1933 by Orton Englehardt, a citrus grower and native of Glendora. The design offered slow rotation and uniform watering, benefits long sought by local irrigators. Clement M. LaFetra, a friend of Englehardt, urged early patent application. A patent was awarded on December 18, 1933. Englehardt, with no entrepreneurial aspirations, assigned all rights to LaFetra and his wife Mary Elizabeth. Production began in the LaFetra family barn on October 13, 1935.
