With reference to Mr. Olley's note attached, it would be advisable for both direct current motors to be driven by the same source of electricity, say a battery, so that the speed fluctuations due to the electrical supply would vary together. Mr. Olley should visit the M.L. Works at Coventry on his way to Derby, when next going to the Works. R.{Sir Henry Royce} 2918 | ||
