| BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} Copy to - BJ. HS.{Lord Ernest Hives - Chair} ORIGINAL. DA{Bernard Day - Chassis Design}1/M14.9.28. "SS{S. Smith}" EXHAUST SYSTEM. X7230 Herewith we send the following drawings dealing with parts of the exhaust system: (1) N. sch. 2703. - Front end of Exhaust Pipe. (2) N. sch. 2704. - Forward Stay. (3) N. sch. 2705. - Silencer. (4) N. sch. 2706. - Swan neck and fish-tail. There is a general arrangement, and also a design of the heat shield, to follow. It will be seen that the general idea is two fixed points, one at the forward pipe, and the other at the silencer, with a sliding joint in between. We have endeavoured that the joint shall slide by giving it very long bearing control. The fixed point at the front permits of downward expansion of the pipe, but no horizontal movement. As regards the silencer we have discarded the present pot ends, substituting shallow pressed ends, and we believe that this will cheapen the production. On N. sch. 2706. there is a new type of flange piece for the swan neck, reducing the number of brazed joints. We believe that as shewn it is a comparatively simple forging, but we should like to have any remarks you may have to make. DA.{Bernard Day - Chassis Design} | ||
