INTERRUPTER.
Specification of Letters Patent.
Patented Nov. 10, 1908.
Application filed July 10, 1907. SerialNo. 883,010.
citizen of the United States, residing at Lansing, county of Ingham, Stateof Michigan, have invented a certain new and useful Improvement in Interrupters, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanyin drawings, which form a part of this speci cation.
My invention relates to "an interrupter,
especially to interrupters to be used with sparking coils for gas engines. In the accompanying drawing :-Figure 1, 1s a diagrammatic view of an apparatus embodying my invention, in connection with a two cylinder gas engine and the ignition apparatus therefor. Fig. 2,'is an'elevation, partly in section, of the mterrupter. Fig. 3, 1s a plan view of the same.
The reference letter A designates the interrupter as a whole.
B 15 the battery, C and C the circuits, in
which circuits are sparking coils D and D the primaries of said coils being interposed in the circuits.
E, E indicate thetwo cylinders of a gas engine, and F and F the sparking plugs therefor. v
f, 7, indicates the secondary circuit from the sparking coils D and D .5 v
G is a cam of conducting material adapted to be rotated by the engine. 1
I, I, are brushes in the circuits C, and C respectively. The cam G is adapted to conleg 2, and 3 is acylindrical extension-from the leg 2, forming a pole iece of opposite polarity to that of the po e'piece 5 within and concentric with the pole piece 5. By this arrangement a strong, permanent magnetic field is produced between the annular pole piece 5 and the inclosed cylindrical pole piece 3. p
4. is a piece of non-magnetic material, as brass, sleeved over the pole piece 3, and passing within the pole piece 5, to secure a definite and fixed relative position of said pole pieces. I 6 is a plate of insulating material supported upon the pole piece 5.-
7 is a binding post upon one end of the plate 6, and 8 is a binding post upon the other end of said plate.
9 is a goose neck secured in position upon the plate 6, and connected with the binding post 10 is a thumb screw having a contact point at its lower end adapted to be adjusted longitudinally in its support in the goose neck 9 by screwing it up or down.
12 is a tongue or plate of resilient material secured to the plate 6 and in connection electrically with the binding post 8.
11 is-a small resilient plate of metal secured upon or near the free end of the plate or tongue 12, parallel thereto and insulated therefrom. The plate 11 is secured to the plate 12 at its left hand end, as shown in Fig. 2, and is free at its other end, at
which end it is adapted to be contacted by the lower end of the thumb screw 10.
13 is a light coil or solenoid of insulated conducting wire. One terminal of said solenoid is connected, as indicated at 14 with the plate 11; the other end of, the conductor of said solenoid is connected electrically with the plate 12. The solenoid 13 is supported by the plate 12, so as to extend between the pole pieces 3 and 5.
The operation of the above described device is as follows :The thumb screw 10,
being in contact with the plate 11, a circuit In the above described apparatus, I avoid.
the use of a heavy armature and the necessity of creating a magnetic field at eachbreak of the circuit, the inductance is also negligible, and therefore does not interfere with theaction of the coil, or the flow of the current thereto, and the action of the vibrator or interrupter is not dependent upon the degree, or fact, of the magnetization of the core of the coil.
What I claim is 1. In a make-and-break apparatus, th combination of means for creating a permanent magnetic field, a contact point, a tongue adapted to make connection with said contact point, a conductor secured to said tongue and located in the magnetic field,
and means for passing a current through rent is passin through it.
comet said conductor, said conductor being so arranged that it shall act to" draw said tongue away from said contact point when the our- 2. In a ma eand-break combination ofmeans for creating a permanent magnetic field, a contact point, a tongue having a contact plate secured thereto at one end and adapted to make-contact with said contact point at the otherend and insulated from said tongue, a conductor secured to said tongue and connected at one end to said plate and at the other end to said tongue,
and means for sending a current throu h said tongue, conductor, and. plate, for t e' purpose described.

In testimony whereof, I sign this specification in the presence of two witnesses. CARL E. PEARSON. Witnesses G. W. NICHOLS, Barman PRATT NICHOLS.
