| X719 N5409 Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}1/LG. 15th. Feb. 1924. Messrs. Ferodo Ltd., Sovereign Mills, Chapel-en-le-Frith, England. Dear Sirs, We are sending an order through for some friction discs we require making from Ferodo Fibre whose co-efficient of friction was given to us on your diagram No.35. These discs are working under light unit pressures and low speeds. If the fibre therefore will stand working to these limits and also can be held by rivets in the same way as Ferodo, it will be suitable for our purpose. We should be glad if you will let us know if you find, for any reason, you cannot make what we require. Yours faithfully, | ||
