PENDLETON 481 6 LINES LONDON OFFICE, 57, VICTORIA STREET, S.W. CLIFTON JUNCTION. NR MANCHESTER OUR REFERENCE EGM/LB. 16th June, 1921. Messrs. Rolls-Royce Ltd., Nightingale Road, Derby. Dear Sirs, X.4288 Our Present Standard 6 BXE.5 Batteries. We beg to acknowledge receipt of your letter, Ref.MFC8/T., of the 15th inst. We are sorry to hear that you have had any trouble at all with the lead washers. We fully anticipated that these would be quite satisfactory with the modified design in which the lead pillar is brought well above the lid {A. J. Lidsey} and an antimonial lead sealing nut screwed down over it holds the lid {A. J. Lidsey} in position. There is consequently no risk of creepage. Any corrosion of the brass washer has presumably been caused through spraying on charge. It could be avoided by keeping the terminals well coated with vaseline. The advantage of the brass washer is that it secures good electrical contact between the terminal stud and the take-off. If lead washers are substituted then it is necessary to depend upon the under face of the lower lock nut for this contact. If you feel that you prefer to forego the advantage of the best possible electrical contact in order to secure the immunity of trouble from corrosion, we agree that the brass washers should be changed for antimonial lead washers, and if you will let us know the number of batteries to be dealt X.4288 RECEIVED STAMP: FC JUN 17 1921 RECEIVED | ||
