He had with him Segrave's Phantom II and also 1-WJ- the London Trials Car- and I discussed many point of interest which are at the moment under consideration. With regard to the 'jellying' trouble, there appears to be no doubt whatever that the scheme "comparatively simple", which has now been devised for dealing with cases where this occurs, is entirely effective for preventing any undue oscillating movement of the radiator. 1-WJ, which was an extremely bad case of this and most stubborn to deal with, is now entirely free from the trouble, also Sir Henry Segrave's Phantom is now also free from this trouble. In both cases the device referred to has been fitted. This is based upon the fact that if the radiator is supported only at its centre by the bottom in such a way as to be able to pivot and its proper vertical position is maintained by the provision of a spring supporting each lower corner in front of the radiator, all tendency to oscillate can be removed. The parts necessary for this are not at all obvious in fact, they would have to be hunted for. Consequently I accepted 1-WJ for our Trials Work and in the case of Segrave's car - 80-WJ - no reference was made to these details whatever. Segrave was not interested in any method we may have employed to improve his car, but only in the fact that he was extremely pleased with the general improvement. He considered the steering perfect, and the car, plus his special shock absorbers now fitted, held the road in a way which he did not wish to criticise at all. PN.{Mr Northey} | ||
