Steadman Esq., Messrs. Rolls-Royce Limited. DERBY. Dear Mr. Steadman, I am enclosing Drawing No. BGA. 3201 showing the suggested arrangement for your Bonnet Louvre Thermostat. The calculations involved are shown on the drawing. I do not think it is necessary to provide any form of linkage between the top of the moving bellows plate and the short arm of the bell crank to compensate for the radial travel of this latter part, as the flexibility of the bellows will, I think, look after this satisfactorily. I shall be glad to have your comments in due course. Yours sincerely, W. Martin-Hurst. ENCL: | ||
