(sheet 2) are held open normally and have to be closed for the starter to operate, while in the second scheme the points are normally in contact when the engine is not running, but are held open when the dynamo voltage begins to build up, the holding out current constituting a wastage. Both schemes have been demonstrated practically, and Rm{William Robotham - Chief Engineer}/Wst. favours the first one, but wishes to make a further experiment with the second scheme to enable us to arrive at a definite decision. (3) Starter Production Setting. It has been arranged temporarily on production to increase the dimension governing the closing point for the main switch so as to cover existing production requirements, but it is agreed that this should not be regarded as a permanent departure from the standard laid down. (4) Shape of Engaging ends of teeth. As an alternative to the existing rounded engaging ends which have to be done largely by hand, it is agreed that a model shall be prepared of a pinion and flywheel ring with machined chamfered ends, and that these shall be tested on an engine after inspection.
