| To BY. {R.W. Bailey - Chief Engineer} from HS. {Lord Ernest Hives - Chair} c. to Wd. {Mr Wood / Mr Whitehead} c. to EP. {G. Eric Platford - Chief Quality Engineer} OCT 18 1920 X3566 RECEIVED. Hs {Lord Ernest Hives - Chair} 3/LG28.10.20. X.3566. RE. FAN BELTS WITH FIBRE INSERTS. X.3438 We agree with the Test Department that the Whittle type belts with the fibre links should not be used on our cars because of the noise they cause and risk of breakage. In our memo hs {Lord Ernest Hives - Chair} 1/LG19420 addressed to OY. copies to Srn, BN {W.O. Bentley / Mr Barrington} , and Mr. Humpston, we did condemn the belts with fibre links. We condemned them because there was not sufficient elasticity in the fibre. We were under the impression at that time that the belts from Canada with fibre links had been cancelled because of them being too large for our pulleys. The further belts of this type 9/16 instead of 5/8 which were sent in to us, were condemned because of them breaking, - see our memo. Hs {Lord Ernest Hives - Chair} 5/LG11.12.19. addressed to BY, copy to BN. {W.O. Bentley / Mr Barrington} We certainly think that the best thing to do is to get rid of the belts as quickly as possible at the best price we can get for them as we do not think they will ever be suitable for our cars.
