Summary. Reduction on the total load of the mill due to better lubrication : Shaft Speed of Mill and Engine No. I increases 0.3 per cent. while there was no increase on Shaft Speed of Mill and Engine No. 2. Test No. 3. Tests Made in Massachusetts, U. S. A. A Speed and Power Test Upon a Cotton Mill Run by Water Wheels. A complete record of speeds was taken for each of the three days of each test, combined with careful observations of the Gate Opening. Wheel Speed, Water in the Wheel Pit, Head, from which was estimated the cubic feet per second, the Mill Power and the Horse Power according to well established rules. The result of this test is that the reduced friction caused by the use of the New Oils allowed the mill to operate at less gate opening on wheels; owing to this less opening and less water required, the water in the Wheel Pit was less. The Penstock Gage shows. higher during the last test Amount of water used was reduced Mill Power which is figured on the basis of cubic feet of water per second is reduced... The Horse Power (figured by the speed and opening of gate and head and Penstock openings) is reduced . . 3.56 66 Yet with the reduced amount of water used the speed of the different sections of the mill increased from 1.21 to 2.81 By using the New Oils the Mill is able to produce from 2 New Oils. 1904. Test No. 4. Test Made at Warrington, England, COTTON SPINNING MILL TEST. Engines -Two Tandem Compound side by side (Double Tandem Corliss Compound), 46.5 R. P. M. Steam Pressure 120 lbs. superheated to 420 degrees Fahr. at stop valve. Developing over 1,400 I. H. P. Machinery Operated - Ring and Self-actor (mules), Spinning and all preparatory machines. Complete Test -8 days. 8 indicators. 2,848 indicator cards. 7 operators. This test covered a period of two years, so a brief summary of the machine corrections will be given in order to show how the test was worked to a comparative basis. The Mill Management wished to see the result of the application of the New Oil upon each separate class of machinery which made this very extensive but exceedingly interesting test necessary. The full report covers 46 pages. Difference of Averages 2.9 H.P. or 0.2 per cent. on Average of Test. Number of Cards. Difference of Averages 13.9 H.P. or I per cent. on Average of Test.
