tons on hour...570 feet per minute... at l^iumbus and Southern Ohio Electric Co. plant problem was to draw coal overland from {Eoe area .6.759 feet from the plant me of its IjtostbA' station. The road distance for truck or rail ^olage.wfcj much longer. ^'Careful studies Indicated belt haulage by the [33t!route would be most economical. Jeffrey en^joeen were given the job of designing and installing fwhst 'i* believed to .be the longest belt conveying ^tectt in the country using a 24" belt Co*l for the Poston power plant now feeds in Jewired and weighed quantities from the mine supply/by tTiearu of a Jeffrey Waytrol onro a 3,448 foot 'incline belt with a lift of 172 feet. This takes it to feeftranifer point where it starts a 3,291 foot decline to the plant. Both belts, 24" wide, carry 300 tons of coal an hour at 370 feet per minute over Jeffrey Re liance idlers. At the discharge end a 36" Jeffrey Boom Stor age Conveyor feeds the hopper. Two Jeffrey-Traylor Vibrating Feeders at the bottom of the hopper feed 300 tons an hour onto a 36" belt conveyor-that rises to the crusher house. A 36" belt under the crusher carries the same 300 tons an hour into the plant to keep the big Poston bunkers continuously fed. That's Jeffrey engineering . . . for the long haul, accurate weighing, the correct feed, and the proper size. FOR THE LONG HAUL Jeffrey Crvther tor reducing ovortlie cool lo the detlred itokor clca.
