ELECTRIC-LIGHTING nrrima'rus.

Specification of Letters Patent. Patented Feb. 19, 1918.

Application filed July 30, 1917. Serial No. 183,608.

To all wh'om it may concern Be it known that 1, WILLIAM HENRY Hoxscnnenn, of the town of Welland, in the county of Welland and Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Electric- Lighting Apparatus; and I hereby declare that the following is a full, clear, and exact description of the same.

In my concurrent application for Letters Patent of the United States, Serial No. 122,913, filed September 29th, 1916, I have shown and described an electric lighting ap paratus for vehicles, comprising a switchcontrolled headlight circuit, a switch-controlled resistor circuit connected with the headlight circuit, an auxiliary light circuit connected with the resistor circuit, and a switch-controlled shunt circuit connected with the auxiliary light circuit, the circuits being so arranged that the closing of the headlight, resistor and shunt circuits will cut out the resistor and auxiliary lights for the brilliant illumination of the headlights, and the opening of the resistor circuit and the closing of the headlight and shunt circuits will place the resistor in series with the headlights for the dimming thereof, without illuminating the auxiliary light, and the opening of the shunt circuit and the closing of the headlight and resistor circuits will cut out the resistor and place the auxiliary light in series with the headlights for the brilliant illumination of the auxiliary light and the dimming of the headlights.

My present invention relates to an electric lighting apparatus for vehicles, in which the circuits may be selectively controlled for the brilliant illumination of the headlights and the non-illumination of the auxiliary light, the dimming of the headlights and the nonillumination of the auxiliary light, and the dimming of the headlights and the brilliant illumination of the auxiliary light; and it consists essentiallyota switch-controlled 'lnain lighting circuit, a shunt resistor circuit connected with the main lighting circuit, and a switch-controlled auxiliary lighting circuit connected with the main lighting circuit, whereby the closing of the main lighting circuit for the brilliant illumination of the main lights will open theauxiliary lighting circuit; and the closing of the auxiliary lighting circuit for the brilliant illumination of the auxiliary light will open the main the contacts h and m, the auxiliary lighting circuit and shunt part of the current through the resistor for the dimming ot the main lights; and the opening of the main and auxiliary lighting circuits will shunt the current through the resistor for the dimming of the main lights and the nonillumination of the auxiliary light.

The'drawing represents a diagrammatic View illustrating the arrangement of circuits. V

(1 represents the source of current, which may consist of a storage or other battery. 6 represents a conductor leading from the source of current a to the contact 0 of the mainswitch 0. (Z represents a conductor leading from the contact 0 ofthe main switch 0 t0 the contact 6 of the control switch 7. 9 represents a conductor leading from the contact h of the control switch f to the lamps i of the headlights j. 70 represents the return conductor from the lamps i to the source of current a. Z represents a conductor leading from the contact my to the lamp 0 of the auxiliary light p. is represents a return conductor leading from the lamp 0 01 the auxiliary light to the return conductor 7c, and 1" represents a resistor in shunt to the conductors d and g.

For the operation of the lighting apparatus, the main switch 0 is closed, so that the currentmay circuit from the source a, conductor 6, switch 0, to the conductor (5. When the switch f is in a neutral position between light p is cut out and the current passe from the conductor 0?, by means of the resistor 1', conductor g, headlight lamps z' and return conductor 7a, to the source of current a, the headlight lamps, during this circuit. being dimmed to the extent of the resistance offered by the resistor r,

When the switch f closes the circuit from the contact e to the contact h, the current passes from the conductor cl, by means of the switch f, conductor g, lamps of the headlights j and return conductor in to the source of current, this being the direct circuit from the source of current a to the lamps of the headlights, and which. when closed, renders the resistor inactive, and cuts out the auxiliary lighting circuit so that the full strength of the currentv may be utilized for the brilliant illumination of the headlight lamps.

When the switch f is moved to close the circuit from the contact: e to the contact m, the current passes from the conductor (Z, by means of the switch 7', contact m and conductor Z, to the lamp 0 of the auxiliary light p, returning from the lamp by means of the conductor is to the return conductor is, this circuit brilliantly illuminating the auxiliary lamp, part of the current finding its way to the headlights and dimly illuminating them.

By means of this apparatus, it is possible: (a) to dim the headlights without illuminating the auxiliary light, when traveling through cities, towns and villages; (b) to brilliantly illuminate the headlights when traveling on dark roadways, without illuminating the auxiliary light; and (a) to dim the headlight when approaching other Vehicles or pedestrians, and illuminate the auxiliary light, which may be directed to the road-side.

While the use of the apparatus; has been described in connection with the headlights, I wish it tobe understood that it may also be used in connection with the side lights, and that therefore, the term .headlights will be construed to mean the main lights of the vehicle.

Having thus fully described the nature of my invention, what I claim as new and desire to secure by Letters Patent; is

An electric lighting apparatus for'vehicles, comprising a three-contact switch, headlights, a conductor from the source of 'current to one contact of the switch, a con- WILLIAM HENRY HON SBERGER.
