Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale}5/MH.{M. Huckerby}23.4.38. BENTLEY III BIJUR FEED FRONT SUSPENSION. At present a bijur feed is taken along the torque arm and to allow for movement of same a coil of pipe is provided near the ball joint. The coil is placed above and in front of the ball joint. Owing to the geometry error thus introduced the pipe fails. The best place for the coil is mounted on the ball joint casting, as this gives perfect geometry. We are going to rig this up but for a final scheme a boss is necessary on the casting to receive the stud holding the coil of pipe. Will you please amend the drawings. The pipe coils in the bijur feed to the rear springs are placed in an extraordinary position and fail regularly. However, as threaded shackles are being introduced on this car the feed to rear springs can, we understand, be taken through them and no change in the position of the pipe coils is necessary.
