Actually, some little time ago I went for a short run in this car, and although this run did not provide a very strenuous test the springing did seem to be satisfactory. I am wondering whether it may be of any interest to you and for this purpose I am enclosing herewith a blue print which Mr. Sartoris has sent me, and also the following extracts from his letter:- "I enclose a blue print of this new design. You will see that the coil spring now acts directly on the stub axle forging: the other end of this spring is connected to the axle beam through a tension rod. The links are, therefore, only normally called upon to carry the loads set up by the couple arising from this overhang of the wheel in relation to the Spring centres: they still, of course, have to take - one - | ||
