"ELMSTEADHenry Royce's home in West Wittering," WEST WITTERINGHenry Royce's home town, NR. CHICHESTER. Mr. J.C. Bentley. ROYCE LTD. MANCHESTER. Dear Mr. Bentley, A.C. & D.C. BRUSH-HOLDERS. Is it possible that the same design would do for D.C., as well as A.C., if modified to single end, and side by side brushes? [Handwritten annotations on diagram] Cables might damp vibrations. Motor cover. This piece may need a window for end of cap to pass into. The square bar must be rigidly held to motor frame. Drive it into square broached hole in drop forged plate which has two screws or bolts through motor cover. Outer plate and large or slotted holes to place it very near collector rings. Yours faithfully, F.H. Royce | ||
