A pplication filed February is, 1905. Serial No. 245,345.
To all whom it may concern:
Be it known that I, ADOLF HERZ, a sub ject of the Empire of Austria-Hungary, and resident of Vienna, Austria-Hungary, have invented a new and useful Ma eto Alternating-Current Generator, of which the following is a specification.
My invention relates to a magneto electric current generator with the object in view of producing a current of high tension and consequent effective sparking under a low s eed of rotation and to prevent, to a marke degree, the demagnetization of the permanent magnet employed.
With these ends in view, my invention consists in putting the primary current furnished by the motor'in short circuit and breaking this short circuit at or near the maximum of its strength at each half period and further in forming a closed circuit around difierent arms or sets of arms of the magnet. This short circuit and the breaking of it may produce the high tension for sparking either in the secondary coil of a transformer. or such secondary coil may form a part of and be intimately related to the primary coil.
In the accompanying drawings, Figure 1 is a view in end elevation partly in section of the generator and interrupter as set u for use, and Fig. 2 is a longitudinal centra section through the same.
' The a paratus may be set up for use in a practice way by providing acylindrical casing 26 with bearings in its ends for the reception of a shaft 27, the said shaft 27 being provided with a permanent magnet fixed thereon, 1preferably in the form of a series of disks 28 aving their peripheries sub-divided to form arms 29, the said arms being arranged in alinement throughout the series of disks and one series being separated from another b means of rods 30 located at the inner ends the spaces between two successive series of arms and connecting plates 31 and 32 at the opposite ends of the magnet, the plates 31,
- 32, and the tie rods being formed of suitable conducting material, copper, for example, to set up aninduced current of electricity around the arms of the magnet and thus revent toa very considerable degree,
the emagnetization of the magnet in use. These circuits, through the rods 30 and plates '31, 32, are induced by the magnetic assing from one series of arms to another. Within the casing, the armature is provided with a series of coils 33 which may be made up of primary and secondary coils,
or, in the event a transformer is used exterior to the casing, the coils 33 maybe primary coils alone.
On the shaft 27, exterior to the casing, a brush 34 is attached and insulated from the shaft, the said brush being constructed to travel along on the interior face of a ring composed of sections 35 of brass or other suitable conducting material, the said brass sections 35 being insulated from one another by means of thin insulating matter 36 so that the width of the brush will bridge momentarilythe insulation and connect twoadjacentsections during the travel of the brush by the rotation of the shaft 27. These sections 35 are alternately connected with the opposite poles of the armature,'and the short I circuiting resulting therefrom,
during the slow rotary movement of the shaft 27, will serve to produce the spark as the tension of the current will be increased during the passage of the brush along the face of a section and the spark will promptly be produced the moment the brush ceases to bridge the insulation. 7,
It is obvious that the making andbreaking of the circuit can be effected in mimeous ways.
The brush 34 has no other function than to electrically connect two a consecutive 'lates of opposite polarity at the moment w en it bridges the insulation between them; In the matter of preventing the demagnetization of the permanent magnet when a variation is produced in the lines of force crossing the magnet arms, an induced =current begins to flow through the conductors against this variation and consequently against the demagnetization of the magnet.
What I claim is: The combination with an alternating our- I surrounding the arms and this current reacts ioo rent generator provided with a. multipolar resenee of two witneses, this 11th day of rotary permanent magnet, of a, closed circuit ebruary 1905.
around the arms of the magnet for receiving t an induced current to prevent the demag- AD HERZ 5 netization of the ma et. Witnesses:
In testimony, that claim the foregoing as FREDK. HAYNES,
my invention, I have signed my name in S. SUNDGmrrv.
