He also mentioned the fact thatbrakeshoe cost had been reduced approximately 30 percent for the first years operation with metered Thompson brought out the interesting point that Poor Operation 600 <$400 E< w 20 50 30 40Seconds |\ CHICAGO ELEVATED RAILROADS CHARTS OF GOOD AND POOR OPERATION OF CARS, USED IN INSTRUCTING MOTORMEN. 40Seconds■ 68-Sec. Run of 1856Ft. - marked savings in energy consumption. Mr. Lanphierthen said that the coasting clock was introduced inAmerica in 1908 and meters in 1910. He was of theopinion that either instrument was just as effective inbringing about energy savings if equal intelligence wasapplied to the data they produced. Mr. Lanphier then described the plan employed ingrading men when meters were used, and he believedthat the average of all the men in the various classesof service was a fair measure of their efficiency. Hesaid that -the ampere-hour meter was so constructedthat it recorded the total ampere-hours consumed re-gardless of the voltage. The same general constructionhad also been applied to the watt-hour meter, and in itthe error had been reduced to a very low point. Inservice the Economy meters had effected savings whichpaid for them in a relatively short time. In closing stated that his interests were in common withthe railways, namely, that of produc
