| Mr Wormald. N4/B28212 [STAMP] 23 FEB 1912 L eCanadel, 23rd February 191 Members of the Technical Committee. Re Fan Belts. Please rig up some tackle to test, say, three watta-watta and three link whittle belts. They should all be run on the same size pulleys and driven off the line shaft. The apparatus should be run until all or a number of the belts break, and a careful record of the performances of the various belts should be kept. Care should be taken that the tension on all the belts is equal at the commencement of the experiment. [WATERMARK] DICKINSON BOND Thos, Nadin. x196 | ||
