Rick Rice, owner and operator of Phoenix Energy in Oilmont, points to a wooden bushing on the arm of the 'dummy,' a 3000 pound block of concrete. The dummy is used to balance his rod line system that powers three oil well pumps from a single power source. Technically called iron rod jerk lines, the systems came to the Oilmont area, north of Shelby, in the 1920's and were widely used in the Kevin-Sunburst Oil Field. Rice owns three operable rod line powered fields, some of the few still standing.
