This column is for Name of Person addressed. DATE. opinion that he thought the springing of the car was excellent. I have not been able to test this car myself to specially notice this point but I have just been experimenting with a car which is on test and about which there was a complaint that although the car was loaded up to correct weight the springs were poor. This I found was actually the case but noticed that although the body bounced about considerably the ballast which was resting on some springy floorboards appeared much more steady, on fixing the ballast on to a more steady portion of the body the springing was considerably improved and I demonstrated this more fully by still further tests. This appears rather an important point in the question of springing that is that the whole body should get as dead weight on road springs. It is quite possible therefore that the springing may be influenced by the way the body is fixed and whether the frame has a certain amount of "give". E.P. This sheet must be filed with the correspondence to which it refers. | ||
