E.{Mr Elliott - Chief Engineer} A.{Mr Adams} C. AGREED BRAKING SYSTEM. X.9940. Herewith we send N.sch.1786., shewing some suggested modifications to the braking system fitted to the above car with the object of removing some of the very evident faults that it possessed when we tried it the other day. We suggest that both lengths of lever should be tried because though the 4" one will give the more effective braking, it may be decided that the loss of wearing allowance is too great. As you will see these levers can be easily and immediately got on to the existing gear by simply reverting to the old jaw piece for the gear lever radius rod and lifting it up sufficiently high to miss the rod. On this drawing we have made some notes of the points on the whole of this braking system which are going to be improved. Referring to the R.M. system which is now being tried we understand that you are going to add the long levers already instructed to the pressure screws as soon as possible. We should like to point out that if you apply the RRM scheme to the agreed scheme as shewn on N.sch.1774 you can use 3" and 4" levers on the pressure screws. We suggest therefore that if this scheme is assembled this is an experiment that should be tried. DA.{Bernard Day - Chassis Design} | ||
