RADIATORS FOR CHASSIS. Mr. Royce was very emphatic that we should be very certain that the radiators we fitted on future cars were going to be satisfactory He considers the radiators were one of the worst features on our pre-war cars. He agrees that if it cannot be improved upon, we should use the Marston round tube radiator, similar to the ones we tested previous to the war. He would like, however, to know the construction of the Marston Radiator, for instance, the tubes are parallel which makes it appear that they have ferrules. He would also like to know the thickness of the side plates, Mr. Royce suggested that these should be stiff enough so as to act as a bonding. In considering a new radiator, Mr. Royce would prefer the 10 mm. diameter tube 120 mm. long i.e., the standard type of tube which we have had submitted to us by Mr. Foy and other people. Mr. Royce is not very keen on the expanding hexagon ends, he thinks that there is a big risk of them being partially split when they are expanding. Mr. Royce has an idea that we might use round tubes with square ends and so be able to insert some bonding wires. Mr. Elliott is going to send a drawing of this. Mr. Royce is in agreement to having a radiator made by Mr. Foy with a pressed tank so that the corners would have a small radius. This radiator should be fitted on to a car and submitted to the Sales Dept. for approval. He considers the tank should be | ||
