Patent 383279 Tesla

[gyulasun]

Does anyone have a copy of patent # 283279
  It is the one for the concept of placing a close coil on a rotor pole mentioned in the last page of three

  Thanks for taking the time to help locate it if you do so.

Hi Doug,

I think the problem is a misprint in the patent number where Tesla referenced his earlier patent # 383279 of May 1, 1888 in the link above you showed (in the 3rd gif file).

I based on my search on the date of May 1, 1888.  It turned out he had been granted actually 7 patents on that day!  They were given as follows, source is from here:
http://en.wikipedia.org/wiki/List_of_Tesla_patents

U.S. Patent 381,968  - Electro magnetic motor - 1888 May 1 - Mode and plan of operating electric motors by progressive shifting; Field Magnet; Armature; Electrical conversion; Economical; Transmission of energy; Simple construction; Easier construction; Rotating magnetic field principles.
U.S. Patent 381,969  - Electro Magnetic Motor - 1888 May 1 - Novel form and operating mode; Coils forming independent energizing circuits; Connected to an alternating current generator; Synchronous motor.
U.S. Patent 381,970  - System of Electrical Distribution - 1888 May 1 - Current from a single source of supply in the main or transmitting circuit induce by induction apparatus; Independent circuit(s); Electric distributor.
U.S. Patent 382,279  - Electro Magnetic Motor - 1888 May 1 - Rotation is produced and maintained by direct attraction; Utilizes shifting poles; Induction magnetic motor.
U.S. Patent 382,280  - Electrical Transmission of Power - 1888 May 1 - New method or mode of transmission; Dynamo motor conversion with two independent circuits for long distance transmission; Alternating current transmission; Includes a disclaimer; Economic; Efficient.
U.S. Patent 382,281  - Electrical Transmission of Power - 1888 May 1 - Improvements in electromagnetic motors and their mode or methods of their operations; Motor is wound with coils forming independent circuits on the armature; Armature is mounted to rotate between two different poles; Armature will eventually synchronize with that of the generator; Windcoils or coils on the field magnets; Expose to continuous current to maintain a permanent field.
U.S. Patent 382,282  - Method of Converting and Distributing Electric Currents - 1888 May 1 - Related to electric distribution systems; Current is from a single main source or suitable transmitting circuit; Induction into an independent circuit; Divide the current from a single source; Transformations; Discovery of method to avoid prior liable and dangerous methods; True Dynamic induction.

So the most probable patent #   is 382,279 (and not 383,279).  Now you may study this (I have not done so) to find it out from the texts.

 Thanks Gyula I got it to work now. Lot of dang patents ,when did he sleep? Guess if you have no wife or kids you can get a lot more done.
