SPECIFICATION forming part of Letters Patent No. 500,359, dated June 27, 1893.

Application filed February 9, 1893. Serial No. 461,675. (No model.) Patented in Germany February 19, 1891, No. 63,938; in England Jannarylti, 1892, No. 936, and in Belgium March '7, 1892.

Conse' quently the magnetic core of the Gramme like ring is magnetized and the armature s of the receiver caused to assume the position of strongest magnetic effect, which is that corresponding with the position of the transmitting arm *3.

It will be readily appreciable that with the use of sufficiently powerful currents transmitted through the conductors to the armature s of the receiver maybe caused to exert considerable power, thereby rendering it possible to utilize said armature either in the direct application of power to a rudder of a vessel or to the control of mechanism of any nat re desired by the user.

"10 not limit myself to the special form of apparatus herein shown and described as I believe it is broadly new with me to transmit electrical energy through a series of electrical conductors to a receiver which will impart to its moving part a motion always corresponding to the moving part of the transmitterand my claim is generic in this particular.

Having thus describ 1d my invention, what I claim, and desire to secure by Letters Pat ent of the United States, is

The combination of a transmitter containing a circularly arranged series of contact plates and a pair of contact brushes and contact rings adapted to connect the said contact plates in pairs with the poles of a source of electricity, with a receiver containing a circularly arranged series of coils connected with each other and adapted to produce a relative angular motion between itself and a diametrically arranged armature, and a group of conductors equal in numberto the contact plates, each conductor connecting one of the said contact plates of the transmitter with one of the junctions between consecutive coils of the receiver, the whole being adapted to operate substantially as described and for the purposes set forth.

In testimony whereof I have hereunto subscribed my name this 18th day of January, 1893.

AUGUST UTZINGER.
