- Editor's Notes
- [drawings precede] "Seeley-- Want to get all the claims possible on this method of working from high to low currents be careful in drawing patent not to call this a tension reducer-- It is amotor system driving a Dynamo mechanically make this distinction broad-- As they cannot recite Ayrton & Perry old suggestion of Motors driving dynamos as a current reducer-- The pith of the invention is 1st-- a motor worked by high electromotive force driving by direction connection a Dyanmo giving out low volts. 2nd Insulating joints in shaft or means so that the high line is absolutely insulated from the low line & arranged so that no cross can occur The earth intervening would in case the wire on one armature came in contact with the base prevent any EMF from entering the 2nd ckt in fact the circuits could be miles apart as far a crossing is concerned (see?) 3rd Placing all the motors in Multiple arc-- strong claim-- or on 3 wire system which is practically the same thing-- 4th-- Arranging one motor to drive two machines as well as one-- This gives a 3 wire unit-- 5= Energizing the fields from the dynamos and Motor from the low current. 6-- also Energizing the Motor field from its own ckt. Dick will tell you what I want to put this patent in for-- E"
