| 1116 Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}/MH.{M. Huckerby} 9th. August 1938. Messrs. Metalastik Ltd., Evington Valley Road, LEICESTER. Dear Sirs, As discussed during your recent visit to our works, we send you herewith a drawing of the rubber block dynamo drive we are using on one of our engines. The drawing shows the space available for the necessary flexibility. We have marked on this drawing that we require a torsional flexibility of 0.6° per lb.ft. torque, and that the coupling must transmit a maximum torque of 5 lbs.ft. We should be glad if you would let us know whether you have any couplings that would go in the existing space, or what suggestions you have for making one that would do so. Yours faithfully, for ROLLS-ROYCE LTD. | ||
