YOUR REFERENCE RM{William Robotham - Chief Engineer}/RC{R. Childs} H.E.West, Esq., Messrs.Rolls-Royce, Ltd., DERBY. 28th September, 1937. Dear Mr.West, At present your Company takes from us for fitment on 4¼-litre Bentley cars, our Exide type 6-MXR9L. The design differs from that of the various batteries supplied for the 40/50-HP Rolls-Royce, the 25/30-HP Rolls-Royce, and the Bentley 3½-litre, as regards the method of sealing round the terminal posts. In the 6-MXR9L type battery we employ what we call the lead insert design, that is to say, a lead fitting is moulded in the lid{A. J. Lidsey} which constitutes the terminal posts above the lid{A. J. Lidsey}, and the groups are burned to projections from these fittings on the underside of the lid.{A. J. Lidsey} In the rest of the batteries (these include 6-XGMR13-1MR, 6-XMR11-1ML, 6-XGMR11-1RL, 6-XMR9-1RL and 6-XMR9-1ML) the terminal posts are integral with the group bars, the lids drop on to collars on the posts, and a seal is made by means of rubber rings and antimonial lead lock nuts. As a result of very careful and extensive surveys of the results in service, we are strongly in favour of the lead insert design, and I am writing to ask if you have any views on the matter before we approach your Company officially for approval to supply all the batteries with the lead insert design. Yours sincerely, | ||
