May 27th.1915. Re Leaky Radiators. With reference to leaky radiators, it would be as well to go through a series of experiments to find out what are the stresses which are the chief cause of a leakage. For instance, I have suggested that we couple an upper tank to a lower tank rigidly, so as to take the weight of the upper tank directly from the base, and not through the crinkled tubes. Should this scheme not prove a success, I would like to try a pair of diagonals front and back of the radiator, as shewn in the sketch herewith. It is not meant to be a practical scheme, but to demonstrate whether it is vertical pressure or horizontal pressure which is the chief source of trouble. When we realise that the radiator has to carry one end of the bonnet in the old design, the vertical pressure passing over the bumps might be quite a serious amount. In the universal bonnet, the side plates of the bonnet are carried direct from the frame, and therefore should impose less vertical stress on the radiator. I send a sketch to show what I mean by vertical and diagonal bracing of a radiator, which could be done in such a way that it could be removed part at a time perhaps. That is to say, if it proved satisfactory with | ||
