Coverley - Production Engineer} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} 3/KT. 8.9.32. BRAKE EQUALISERS. File. We have been measuring the over-all efficiency of the Peregrine brake system. The main point we have discovered is that the equalisers are very inefficient. We do not know whether they will be inevitably inefficient because of their size, but we do know that the one we pulled down had exceedingly bad bediing of the mitre wheels. We should like to try a Peregrine rear brake equaliser shaft on the fitting of which special care had been expended in order that we may know whether to blame the design for this inefficiency. Will you please let us have one to test. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
