April 22nd. 1915. Re Leaky Radiators - R5/IB19415. With reference to the question of reducing the trouble of leaky radiators of the crinkled tube type of which there are a large number on the road, I think that the best way is to change the centres for square tube honeycomb, not bonded. This type stood up well on the bumper with the trunnion type of suspension, of which there are most on the road. As the cost of changing may be high it is advisable to do as you suggest and experiment with various kinds of suspensions. An adaptation of your scheme, which I think we could test with a few rough parts, would be to fix two flanges with central studs to the bottom tank, the flanges being held by screws, the whole being afterwards soldered up. A shoulder on the studs would rest on a cross member which would be fastened to the frame in a convenient manner either rigidly or flexibly. This would be sufficient to make the test to see if the different method of support gave better results. (contd) | ||
