| ORIGINAL To AJS. from EFC. EFC1/T1.10.26. c. BJ. BY.{R.W. Bailey - Chief Engineer} BY/D.{John DeLooze - Company Secretary} PHANTOM SEQUENCE STARTER No.2 SCHEME. We have, as requested in your AJS1/M24.9.26 carefully examined LeC.2298 from an electrical point of view. Except for the possibility of switch chattering referred to by yourself, we can see no reason why the apparatus should not function perfectly correctly electrically. In this scheme we have at the same time (1) By making two units into one. (2) Replaced the non-positive electrical link between the two by a positive mechanical link, which renders unnecessary the three-point press button switch. (3) Eliminated the necessity of the heavy series winding. i.e. referring to the top half of the system, comprising the push button switch and the auto unit. It will be observed that this top half could be applied directly to the present bottom half comprising starter motor unit, actuator, and pinion operated switch, and vice versa, viz. the present system of duplex press button switch and duplex unit could be applied to this new system of motor with sliding armature and armature operated switch, though I doubt if an occasion for making either combination will ever arise. In regard to the possibility of chattering when the engine does not start and power reversals take place between the pinion and the flywheel, has it been considered whether the armature operated push switch could be made to work | ||
