Results. Full Mill Load. MILL OILS. Average of June 14, 15, 16, 1905, (add Machine Correc tion of 5.81 P.S.). NEW OILS.- Average of September 6, 7, 8, 1905, (add Machine Correction of 13.36 P.S.) I.P.S. 263.41 239.35 24.06 The full load on this Cotton Mill was reduced by The load on the Engine, Transmission and Ring 24.06 P.S. or 9.1 per cent. 16.92 P.S. or 14.8 per cent. 7.84 P.S. or 5.2 per cent. 3.6 per cent. 0.3 per cent. 1.55 R.P.M. or 1.3 per cent. This would represent an increase in production, as the production of a mill is largely dependent upon its speed. Both the Relative Humidity and Temperature are against a Reduction in Power. Test No. 10. Test made at Elberfeld, Germany. POWER TEST OF A WORSTED SPINNING AND WEAVING MILL. Engine-Made by Gebruder Selzer, Winterthur, Switzerland, 1890. Tandem Compound Condensing. Cylinders 475 m/m and 570 m/m. Hub (Stroke) 1,050 m/m. Steam Pressure 8 to 9 atmospheres. Temperature at Cylinder 260-270 °C., 70 R. P. M., developing about 320.0 P.S. Machinery Operated Preparing, roving, washing, weaving and finishing machinery for preparing and manufacturing woolen and worsted goods. Complete Test -9 days. 4 indicators. 1,764 indicator cards. 3 operators. The first test was made upon the basis of very cheap American and Russian Oils. The engine was overloaded and more machinery was to be put in the mill. It was a question whether to buy a 30 P.S. electric motor, or buy better lubricating oil. The following test was made to show the effect of changing the oil. As the second test was made in the summer, and the temperature in and outside were so greatly in favor of the reductions shown by the second test, it was decided to run a third test to secure data in regard to the effect of the temperature and humidity. An attempt will be made to show this effect, though it must be remembered that the effect has been on this one mill, and it is not claimed to represent what will follow in every mill.
