UNITED STATES PATENT OFFICE.
JOSEPH ALLAN SMITH, OF SYRACUSE, NEW YORK, ASSIGNOR T0 NER-A-CAR CORPORA- TION, A CORPOBATION OF NEW YORK.
ELECTRIC-CURRENT GENERATOR.
Application filed July 28, 1922.
'1 '0 all whom it may concern:
Be it known that I, Josnrrr ALLAN SMITH, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Electric- Current Generators, of which the following is a specification.
y invention relates to an electric current generator, and more specifically to an apparatus the rotor of which is adapted to be fixed to a revoluble part, for example, the fly wheel, of the internal combustion engine of an automobile or motor boat for supplying a high tension current for ignition purposes and a current of lower voltage for the lights carried by the vehicle or boat.
. One of the principal objects of the invention is to rovide a generator of this type which wil supply, for the lighting system, a current of relatively high frequency, that is interrupted for only short intervals so that the lamps will be illuminated, in effect, continuously and steadily even when the rotor is revolving slowly, thereby obviating the .winking? of the lights which with most lighting systems supplied with current from fly wheel generators, occurs when the engine is operated at low speeds.
A further object is to simplify and reduce the manufacturing cost of the generator with regard particularly to the winding and assembling of the ignition coil.
Both these objects are obtained by pro-- viding a plurality of lighting COlls arranged in two spaced groups, and, in place of the single high tension-coil heretofore used, employing two such coils arranged between the two groups of lighting coils.
The accon'ipanying drawing illustrates, somewhat diagrammatically, a suitable construction for carrying out the principles of my invention. it will be understood. however, that the invention is, not considered as limited to this particular embodiment.
Referring to the drawing, A designates the fly wheel of an automobile engine to the rim of which is secured the rotor of the generator consisting of a permanent magnet B Qf the usual construction, provided with ole shoes B, B of suitable construction. For generating low tension or lighting current a plurality of coils are provided Serial No. 578,092.
divided into two groups, the coils of one of the groups being designated C, C, the coils of the other group being designated C, C. These coils are arranged on a pair of crew ate core pieces D, D of laminated construction secured to a stationary element designated E. Coils (l, C, C, C are connected in series, the circuit wires being designated 10, and the lights indicated at F. In the drawing I have indicated grounded circuits throughout although that is not essential.
Instead of the usual single high tension coil I provide two such coils which are desig nated G, G, and are arranged between the groups of lighting coils C, C, C, C, on cores H, H which are attached to and bridge the gaps between the ends of ,the.
lighting coil core piece D, D. The high tension coils G, G comprise primary windings ll, 11' of coarse wire and secondary windings 12, 12 of fine wire. J designates one of the spark gaps in the combustion chamber of the motor (spark plug). Kisa condenser and L the usual .,interrupter or breaker which ma be provided. withany of the suitable tinting mechanisms (not shown).
The wiring of the ignition system is as follows: 13 is a wire grounded at 14 and connected at 15, it with the primary coil 11 and secondary coil 12, respectively. 17 is a wire connecting the primary coil ll'with the primary coil 11. l8 is a Wire connecting the secondary coil 12 with the secondary coil 12. 19 is a wire connecting primary coil 11 with the fixed terminal 20 of the circuit breaker L, the movable element QI ot' which is grounded M22. The condenser K is connected to wire 13 and by wire 23 with the stationary terminal 20 of the circuit hrcali'er. :24 isa wire from second ary coil 12 to the spark plug .l which is grounded at 25. the usual safety gap being provided as indicated at 26.
it will be observed that. due to the relatively large number ol lighting coils the lighting current will be one of relatively high frequency. The gaps between the groups of coils (l. and C. are comparatively short so that even when the motor is operating at low speed the interval oi time between the excitation of the end coil oi one group and the adjacent end coilot the other group will be short. As a result there be no current supply arrmlgement eiescribed maniac, in ,1 in this respect in the animation. He etafoz'a Winkmg 0 revoivei, 1 101:
