For attention of Mr. E.{Mr Elliott - Chief Engineer} Fowler Clark. Messrs. Rolls-Royce Ltd., Nightingale Road, Derby. Dear Sirs, X.604. Mr. Royce's Battery. X 3317 We beg to acknowledge receipt of your letter, ref: EFC1/T, of the 7th inst., and greatly regret to learn therefrom that some trouble has been experienced with the battery of 3 EXE 5 cells supplied for Mr. Royce's "Buick" Car in August last year. As soon as the first case of failure arising from the cause described in report E2/G22.7.20., accompanying your letter, was brought to our notice, we took immediate steps to prevent a recurrence. We subsequently decided to make further modification which would in no way affect the dimensions or external appearance of the cells, but would introduce into the EXE cell a design which has already given great satisfaction with our other standard type of starter battery - the XC. In this the plates are equipped with feet and the boxes have four bridges or insulated bars instead of two. The positives sit on two of the bridges and the negatives on the other two. This entirely precludes leakage through sediment accumulating on the top of the bridges, and the separators rest on the bridges and consequently extend below the plate to a distance corresponding to the height of the feet. Although this method is in actual operation in our XC batteries, we have not yet been able to complete the change-over in the EXE type, but propose to do so with the least possible delay. We are very gratified to learn that Mr. Royce comments so favourably upon the construction and method of assembling and sealing the battery. While the bolted connections assist in simplifying any necessary repairs Contd. | ||
