| (sheet 2) The latter appears to be equally good for keeping the drum cool, and provided the efficiency of operation is not spoiled I think a very practical job could be made of a pressed metal fan fixed on to the standard brake drum, and with very little added weight. We are at the moment working on this problem with a view to trying the scheme out. E.{Mr Elliott - Chief Engineer} | ||
