| 9 CAM GEARS LTD. CONTINUATION SHEET. Messrs. Rolls Royce Ltd. 22nd November, 1932. We note that you will fit your own controls and we will arrange the bottom of the steering gear box to have an oval flange, similar to that shown on your drawing FB 58276, and the hole through our standard steering tube has a diameter of .80". We are having a test made of the efficiency of the Bishop gear in the castoring direction with a cam giving a ratio of 11 to 1, and we will at the same time send you curves showing the efficiency of a similar gear having our standard cam which is generated with a slightly slower helix. Yours faithfully, For CAM GEARS LIMITED, Hmk. Reutonf. Director as. | ||
