Thefigures for heat loss were reduced to pounds of water condensedper square foot of bare pipe per hour and a smooth curve drawnto represent the average of the results. Some of the co-ordinatesof the curve are as follows; Temperature, degrees 212 259 294 .324 338 365 38SSteam pressure per gage, lb o 100 150 203Steam condensed per , per hour, lb In preparing the table no account was taken of the fact that. G. COOPER ENGINE, CLEVELAND CITY KV. is bolted to the side of the engine bed and carries two rockershafts to arms on which the eccentric rod and reach rod areattached. There are two governors used, the one on the lowpressure engine controlling the trip mechanism of both cylindersand that on the high pressure engine operating a safety stopmechanism. The safety governor holds one end of a horizontallever carrying a weight and connected to the stem of the auxiliarythrottle valve, which is located immediately above the main throt-tle. When the engine speed exceeds that for which the governoris set the horizontal lever is released and the weight acts to closethe auxiliary throttle. The cylinders are lubricated on the forced feed system byImproved Rochester automatic lubricators made by Greene,Tweed & Co.; the lubricators receive motion from one of thewrist plates. The bearings have oil cups to which oil is delivere 1by pipes under a pressure of about 30 lb. pe
