| X4237 BY.{R.W. Bailey - Chief Engineer} from Hs.{Lord Ernest Hives - Chair} Hs{Lord Ernest Hives - Chair}4/LG2.5.23. RE. FAN BELT We are returning to you herewith, special endless Fan Belt supplied by Messrs. Ormerod & Co. which you sent to us recently with your BY2/P6.4.23. This belt ran for 650 miles on a 20 HP. car and behaved very well. After that time the car was put on the dynamometer and when the engine was running at 3000 r.p.m., the belt snapped. After it had broken, the belt felt very hot, and it will be seen by the condition, that in places it has become very hard as though it had been burnt. Hs.{Lord Ernest Hives - Chair} | ||
