E.A.C.II. 45" SPRINGS. --------------------- I am not quite certain whether we ever gave Messrs Firths permission to deal with the 45" spring on the same basis they dealt with the 43 1/4" un-equal-ended type. My impression is that nothing was done. I think we should write to Messrs Firths, and assuming we have not previously given them authority, should authorise them to produce designs for the 45" springs, taking the mean loads in our lists, given, as the springs to work on, and ask them to give us three pairs of springs produced to their designs, the poundage of which should be 1100 and 1150. The drawing of the old spring is numbered F.71924. If you refer to this number and ask Messrs Firths to produce three pairs of springs, and earmark them in a special way so that when they are delivered you will know of it, and I can in turn hand them over to Hs.{Lord Ernest Hives - Chair} it will then put this whole question on a sound footing. It occurs to me that the best way of earmarking the spring would be that when they give us particulars, we will give them a new piece number. BY.{R.W. Bailey - Chief Engineer} | ||
