Cont'd.{John DeLooze - Company Secretary} We are going to reproduce the manufacturing technique we learnt in America on a few more sets of textolite gears and feel convinced that we shall be able to get a more silent front end drive than at present at a considerable reduction in cost. We should therefore likethe necessary designs completing. Bentley Clutch Jaggers. We have observed that as the engine rotates on the Bentley the clutch operation is affected by the geometry of the linkage. We want a design to prevent this. The present Phantom is all right. This will be particularly important when the more flexible rubber mounting is applied to the Bentley engine. Bentley Wing & Lamp Movement. A portion of the Bentley lamp and wing movement is attributable to the torsional flexibility of the frame side forward of the front engine mounting. We have fitted a tubular member between the base of the lamp pillars with beneficial results. As the lamp movement will be accentuated by the P.100 lamps we think this matter should have design consideration. Phantom Suspension. We have demonstrated to you the improved control which we get with the roll rod with the low rating sprung Phantom car. We think we should get outa design for the Phantom and that provision should certainly be made for it on the SpectreCodename for Phantom III. We should also like the design dept. to see whether one cannot be fitted to a Bentley as its application would enable us to fit softer front springs without spoiling the cornering and this should reduce jellying. At present we find it very difficult to put a roll rod on the Bentley experimentally. | ||
