| Cont'd.{John DeLooze - Company Secretary} Minute No. 2. -3- HYl/R.12.6.33. (13) Controls on steering column to be brought up to date. E.{Mr Elliott - Chief Engineer} will submit a model so as to fit to existing car. (14) Engine gear rattles. A scheme is required to eliminate gear rattles. E.{Mr Elliott - Chief Engineer} said a balancing cam and non-metallic gearing are to be tried. Tests are in hand on Bentley to gain information. E.{Mr Elliott - Chief Engineer} said he was of the opinion that an eccentrically mounted dynamo drive would be of advantage in dealing with gear rattles and it was agreed that this should be provided. (15) Timing gear position. The question of the location of the timing gears as to whether they are to be preferred at the back end or the front end was discussed from all points of view and it was unanimously decided that the gears should be at the front end. (16) Automatically adjusted tappets. Hs.{Lord Ernest Hives - Chair} said these are necessary on J.III. engine and E.{Mr Elliott - Chief Engineer} said they would be provided. Exp. Dept. have certain modifications in hand for improvement of this detail. Hs.{Lord Ernest Hives - Chair} said that as we shall have to pay a royalty for the use of this device we may as well get all the information we can from the licensors. By will, therefore, get in touch with Mr. Constantine and obtain all information possible regarding troubles likely to be met with in manufacture and operation. (17) Shock Absorbers and Controls. Hs.{Lord Ernest Hives - Chair} said J.III. car is now running about fitted with hand controlled R.R. dampers using Arens control system and is giving satisfactory results. He recommended that this scheme be adopted until we have something better to take its place. He said they were coming to the conclusion that the fully automatic control will not fulfil all the conditions required. It was agreed that in the first place some form of hand control mechanically operated be used and Design will consult Exp. Dept. to arrange a satisfactory system, and issue designs. (18) Front Axle Control. Hs.{Lord Ernest Hives - Chair} and Rm.{William Robotham - Chief Engineer} expressed the opinion that the present arrangement of front axle control is not really satisfactory with low rating springs. | ||
