| Expt. Report (Contd) -4- Hs{Lord Ernest Hives - Chair}/HmL/T26.5.26. at the ball end over the worst of the bumps on the record. We attach a print of a shock damper arrange- ment that we are trying out on the rear. We have employed a steel sleeve - (a) To facilitate alterations to the free movement and slightly damped movement by changing the sleeve. (b) To strengthen the case. In the sketch 3" free movement is shown. This was to ensure that there would be some unrestrained motion no matter what the variable load. Actually if the centre of the free movement was arranged for two passengers in the back, 1" free movement either side of the loaded position would appear to be adequate. If there are no passengers in the back extra damping should not matter very much. All our tests so far indicate that with 8" spring deflection we get the best results with a good deal of damping and require a certain amount on compression to keep the car off the buffers.
