Exclamation Simple or Compound Helices - That Is The Question

For the most part, right I believe you are.

However, I believe that a possible interpretation of the wording of the patent could include the meaning of the use of compound or simple helices arrangements in some form or another:

The mode of producing or starting the action in the helices consists in the use of a steel or electro-magnet, or a helix, around one of the helices, and
causing a secondary current in the enclosed helix by means of a battery current in the outer one; the action then in either the simple or compound helices increases in quantity to the maximum capacity of the wires to conduct with the existing tension of the current.
Though, I agree that it's probably as you say.
