LINEN SPINNING Mill test.
Engines - Victor Coates, Belfast in 1902. Compound Vertical. Cylinders 12" and 2" diameter, 24" stroke. Steam Pressure 140 lbs. 101 R.P.M. Developing about 100 H.P.
Machinery Operated- Dressing, Cropping, Spinning, Winding, Warping and Looms, as usual for manufacture of high grade Linen goods.
Complete Tests - 4 days. 4 indicators. 920 indicator cards. 4 operators.
The special features of this test are the very extensive observations made upon the temperature conditions of 731 individual shaft bearings, the observations covering a period of eight days under each class of lubrication. At the time of making the observations of the bearing, temperature readings were also taken of the temperature of the room, so that the rise or actual temperature due to friction could be secured.
As more Looms were in operation during the second test than on the first a special sub-divisional test was made in order to secure the power for correction so that both tests could be placed upon a comparative basis. The Machine Stoppages and extra Looms- the H.P. value being secured by the means stated represent the following:
