| 108th Meeting Jan. 4. 12. Mr. Johnson asked the Committee if our engine gears did not become noisy in use. He stated that he had observed a number of Rolls-Royce cars on the road with noisy engine gears. Mr. Platford stated that he had no difficulty in quietening a noisy engine gear, but he agreed that there was some risk of the gears becoming noisy with use. Mr. Johnson was informed that we were still running paper gears, but that we had some Amborine gears (the material used by the Packard Co.) on test, but they had not been yet proved to be satisfactory. We were also running tests with cast iron gears, which up to the present had proved to be fairly satisfactory. [Handwritten note on right margin: 1411] | ||
