| 262? Experimental Dept. Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell}12/MH.{M. Huckerby} 15th. June 1938. The Parsons Engineering Co. Ltd., Town Quay Works, SOUTHAMPTON. Dear Sirs, We are in receipt of your letter of the 14th. and proposal for the coupling of your reverse gears to the Rolls-Royce 30 H.P. unit in Mr. Hall's boat. This arrangement as shown on your drawing Y.65 is quite satisfactory so far as the unit end of the drive is concerned, with the exception that we think it would increase the safety factor to have an extra and opposite keyway to the single one you have shown. The lubrication of the ball race by oil and not grease is satisfactory. Yours faithfully, for ROLLS-ROYCE LTD. | ||
