COMBINED ELECTRIC-LIGHT SYSTEM.
Specification of Letters Patent.
Patented lEeb. 2d, 1914.
Application filed June 9, 1913. Serial No. 772,557.
To all whom it may concern:
Be it known that I, Janus I-IAnvY BURCHAM, citizen of the United States, residing at Danville, in the county of Vermilion and State of Illinois, have invented new and useful Improvements in Combined Electric-Light Systems, of which the fol lowing is a specification.
My invention pertains to electric light systems; and it contemplates the provision of a combined system designed more particularly for use on locomotives and so arranged that an are light and a series of incandescent lamps may be synchronously maintained in a lighted state, and the current may be expeditiously and easily cut oil from the are light while the incandescent lamps are still caused to glow by current passing through the shunt or fine winding of the field coils of the generator, this being advantageous because it obviates the objectionable pumping of the arc lamp which is an objectionable feature of the operation of headlights and incandescent lamps comprised in a system with a shunt-wound dynamo or generator.
The present and best practical embodiment of my invention that I have as yet dovised will be fully understood from the following description and claims when the same are read in connection with the drawing, accompanying and forming part of this specification, in which the figure is a diagrammatic view illustrative of my novel and advantageous system.
Referring by letter to the said drawing: A is an arc lamp, designed to serve specifically in the headlight of a locomotive.
B is a series of incandescent lamps, arranged in circuit and designed to be located in the cab of the locomotive.
C is a switch which may be of any appropriate description, and D is a dynamo or generator.
The apparatus is susceptible for use as a shunt or series machine as occasion re quires. F or instance when the switch C is thrown toward the right to electrically connect the terminals as and b the current will leave the positive brush of the generator and will pass through the series winding 0 of the field coils and the wire (Z to the carbon 6 of the arc lamp, across the arc, the carbon f, the Wire 9, the terminal 2'), the terminal a, and the wire it back to the negative brush of the generator. During this maintenance of the arc lamp in a lighted state, the incandescent lamps B are connected across the brush holders.
It is often necessary or desirable to cause the lamps B to glow after tl e are lamp A is extinguished. To accomplish this the switch C is thrown toward the left to make electric connection between the terminal a and the terminal. 77. IWith this done the current will pass from the positive brush of the generator through the shunt or fine winding j of the field coils, the wire 70, the terminal 2', the switch C, the terminal a, and the wire it back to the generator, the lamps B glowing as before.
It will be manifest from the foregoing that the lamps B are caused to glow when the switch C is in each of the positions stated, and the glowing of the incandescent lamps B is not attended by the objectionable pumping hereinbefore alluded to when the arc lamp A is in operation.
Having described my invention, what I claim and desire to secure by LettersPat ent, is:
1. In a system of electric lighting, the combination of an arc lamp; an incandescent lamp; a generator; a switch; a circuit in which the arc lamp, switch and the serieswinding of the field coils of the generator are included; and a second circuit in which the incandescent lamp, switch and the shuntwinding of the field coils oi the generator are included.
2. In a system of electric lighting, the combination of an arc lamp; an incandescent lamp; a generator; a switch; a circuit including the arc-lamp, switch and the series winding of the field coils of the generator; and a circuit including the incandescent lamp, switch and the shunt-winding oi the field coils of the generator, the latter circuit comprising an electrical connection that extends irom an electrical connection inter- 100 mediate the switch and the negative brush of the generator.
In testimony whereof I have hereunto set my hand in presence of two subscribing witncsses.
JAMES HARVY BUROHAM.
