MAGNETIC-ELECTRIC GENERATOR.

Speciflcationof Letters Patent.

Patented July 28, 1908.

Application filed April 12, 1905. Serial N0. 255,147.

To all whom it may concern:

city of Paris, Republic of France, electrical engineer, and RAOUL ANDRE PERsIN, of Rue dAval, Villiers-le-Bel, Seine and Oise, Re

public of France, mechanic, have invented mprovements in or Connected with Maglowing is a full, clear, and exact description.

Our invention is an improvement in magneto-electric generators, and consists in con tain novel constructions and combinations of parts hereinafter described and claimed.

The object of the invention is an electro magnetic machine characterized by the combination with the rotating secondary of a vibrator or breaker having a retarded action,

the said breaker being carried by the secondary, and being intercalated in the primary circuit, and breaking said primary circuit when the intensity of magnetism on the core.

of the secondary attains a suitable value.

In the drawings-Figure 1 is a side view of the rotatable secondary, provided with our improvement. Fig. 2 is a section on the line Fig. 3 is an end view of the secondary. Fig. 4 is a section on the line A-A of Fig. 1, and Fig. 5 is a section on the line BB of the same figure.

The bobbin a, is provided with two super posed windings, the primary 1) being formed of coarse wire and traversed by a current which is generated at each turn of the core c'by the magnetic flux.

The ends of the primary winding are connected the one at b to a spring plate m mounted on the end of the core and insulated therefrom, and which carries' the contact piece it and the other to the core 0 at b. The secondary d has one end connected to the core at the point I), and the other end is connected with a contact point 6 arranged in the axis of thecore, and having a rubbing contact with a contact f connected with the wire 9 of the secondary current supply.

The armature I0, is of magnetic material and is mounted parallel with and spaced apart from a diamagnetic plate Z, having upon its upper end a hook 1, between which hook contact h and the circuit is broken.

and the body portion of the diamagnetic plate, the.plate l is arranged. The dianiagnetic plate Z is normally in contact with the contact h of the circuit breaker, which is mounted upon a spring plate m.

. In operation the induction coil being rotated, an induced current is generated and the armature 7c is attracted toward the core of the coil.' In the movement of the arma-.

ture toward the core, the upper end thereof engages the hook'portion Z of the diamagnetic plate 7, and is temporarily retarded in its movement until the induced current attains a sufficient value to overcome the resistance of the diamagnetic plate, when the said plate is moved out of contact with the At the moment when the spring'l is removed from the contact iece h,'the primary current is out off, there y producing an induction current in the secondary winding.

It will be noticed from the description, that both the primary and the secondary winding andthe vibratoror breaker are all mounted on the rotary core of the magnet, the vibrator being operated automatically by the action of the induced current, and requiring no mechanical control.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is The combination of a magneto-generator provided with a revoluble core of magnetic material, a primary winding and a secondary winding carried by said core, a breaker mounted u on said core and revoluble therewith, said reaker'being operated automatically by the attraction of the magnetic flux of said core due to its rotation, and magnets disposed adjacent to said revoluble core for inducing magnetic flux therein.

The foregoing specification of our improvements in or connected with magneto electric generators signed by us this 31st day of March 1905.
