Bailey - Chief Engineer} Copy to HS{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} MARTINDALE File Bentley III - Independent Suspension Front Brakes. We send herewith N.Sch.4886 which shows the front wheels, hub, pivot, yoke piece and its bearings, front brakes and drums. We have shown the standard Bentley wheel with 18" x 3 1/2" rim and also the proposed 17" x 4" rim which we believe is being tested on the present Bentley. The hub and spoking is the same for both wheels as at present used. The design of the brakes and brake drums follows that which we have issued to you recently for the Wraith II and Bentley. The brake drum diameter is 12" and this is the smallest possible drum we can use consistent with the design of pivot and brake operation. The cam radius for the front brakes is .365" but we may subsequently increase this when dealing with the overall brake ratios. The pivot follows the standard R.R. practice as used on Wraith II and our front axle cars. Complete particulars are given of the yoke piece, and the top and bottom triangle bearings, but the triangle end will form the subject of a separate scheme.
