April 19th. 1915. Re Leaky Radiators. With reference to leaky radiators of the standard pattern which are on the road, I think you will have to go through a series of experiments to see how these can be altered and suspended so as to make them stand more road shocks. I understood that some time ago we had intended to fix substantial side plates to the top and the bottom, and therefore relieve the crinkled tubes of the water in the top tank. It also might be tested to find out whether we could do with much less water in the top tank, especially with the steam separator top tank and some means of preventing it being over-filled, which would materially alter the weight of the radiator. The third, and most hopeful point, however, would be changes in the suspension. I am not sure whether any benefit was found with the standard type of radiator with the sphere underneath, especially that in which the sphere was carried well underneath, so as to distribute the weight on more of the crinkled tubes than on the very corners. Another way would be to see whether it was worth while having a pressed steel girder right across underneath, and the bottom tank attached to it in various ways, and possibly with spring or rubber connections.
