While considering this alteration to the frame, wemight consider the advisability of putting the cantilever springs out of centre. They are now I believe 54" long, and I think it would be ppreferable to shorten them rather than make them out of centre. With the spiral spring arrangement of which I send an experimental drawing, the increased friction due to shortening of leaves could be compensated for by the use of this spiral spring. The whole idea is that the cantilever end of the frame behind the spring pin( which cannot be trussed) is to be made as short and stiff as possible. F.H.R. encl. exp. drg. | ||
