To all whom it may concern:

Be it known that. I, WILLIAM F. PERSONS, a citizen of the United States, residing at Lakewood, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Automobile- Lamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates generally to automobile lamps and it has for its object to provide certain improvements to the auto-v mobile lamp now in common use whereby the intense glare can be eliminated when desired and a sullicient amount of light-f thrown directly upon the road at the proper distance in advance of the automobile.

Another object of the invention is to provide the improvements in such form, and arranged in such manner as will not interfere with the main or general searchlight functions of the lamp when it is desired-troy employ all of the light rays.

With these objects in view, the invention consists in the arrangement of a supplemental reflector within the confines of the main reflector, preferably adjacent one edge thereof and at a slight 'angle to the axis of the main reflector so that by cutting out the main source of light from the main reflector and cutting in the supplemental source of light within the supplemental reflector a smaller light will be thrown upon Athe road the proper distance in advance of the auto-v54 mobile.

The invention consists also in certain de-` tails of construction and arrangement hereinafter fully described and 'pointed out in the claims.

In the drawings forming apart of this specification Figure 1 is a longitudinal sectional view` of an automobile lamp embodying my invention; `Fig. 2 is a front view of the same; and Fig. 3 is a diagramigitic'- view illustrating the lines of reflection of*Y-` the light rays from both the main and supplemental reflectors.

Inasmuch as my invention can be appliedA to any and all of the well known types of electric automobile lampsIfhave shown the same applied to one in which A indicates the outer shell or body ofthe lamp, and B the reflector arrangedtherein, this reflector being preferablywparabolic and having a Specification of Letters Patent.

Application filed. August 5, 1916. Serial No. 113,217.

central opening in which is arranged the socket for the incandescent light C. This incandescent lamp may be adjustable or stationary as preferred. The lamp is provided with lthe usual glazed front D 4which may be secured `in any suitable 'manner such as a clamping ring E.

' F' indicates a supplemental reflector which -in diameter is slightly less than oneto the main reflector by means of screws or rivets I and it willv be noted that the lower edge of the supplemental reflector is set slightly back from the lower edge of the main1 reflector while the upper edge K is on aline with the outer edge of the main reflector, It will also bev noted that this upper edge K approximates the center of the main reflector and its source of light. Both the inner and the outer surface of the supplemental reflector H are polished to provide reflecting surfaces.

When the lamp is use'd in the city, where the intense glare is objectionable, and often prohibited, the supplemental source of. light 1s employed, the main source being cut out and thevrays of light are reflected downwardlyupon the road directly in advance of. the car, and the reflectors 'being small,

vof the` supp emental reflector can be secured only a sufficient amount of light will be, ro-

jeted to enable the driver to obtain a; c ear vision of the path of travel. Whem how*- 'eventhe car is traveling in .the rural districts or open country and it is desired to use the full power of the lamp the supplemen V tal source of light is cut out andthe main source cut in, and inasmuch as the rear surface of the su plemental reflector is polished to provi e a reflecting surface the lightrays which would otherwise vbe 0bvstrwtecl by said snpplementalreector are.

' most power is needed.

``While I have shown only one'formV of my 4`invention it is obvious that certain changes und modifications cnn be ,mede without departing from the broad principle thereof Within 'the scope and meuningofthe nppended claims.

Having thus describeddiny invention, whetI claim iis1- 'f l. In a lamp, the combination with a main unbroken reflector', of n supplementnl reflector arrengedwithin the confines of the mein reflector and adjacent the edgethereof, Said supplemental reflector being of less diameterthen the main reflector.

Q In a lmnp, the combination with a main unbroken reflector und its source of light, of e supplemental reflector and its source ofrligbt. said supplemental reflector being 'i-renged Within the confines of the main reflector und et :in angle to the axis of saliti main reflector.

3. In e. lmnp, the combination with a main unbroken reflector und its source of light, of e supplemental reflector und its source of light, said supplemental reflector being of considerably less diameter thanthe main relleotor,` arranged within the ,conlines thereof adjacent one edge and at un :ingle to the axis of said mein reflector.

4. In :t lump. the combination with un unbroken reflector und its source of light, of n. supplemental reflector and in independent source of light7 said supplemental reflector being of considerably less diameter than the main reflect-o1' und arranged Within the confines thereof.

In a-lunip, the combination with an unbroken reflector and its sourceof light,.of a supplemental. reflector and its source of light, said supplemental rellector being :Lrranged within the confines of the main reflector adjacent onev edge thereof and .in

advance of the source of light Aofthe mein, reflector, both the inner and outer surfaces of said supplementnlyrellector being reflect-' y ing surfaces.

In testimony whereof, I hereunto atlix my signature. y WILLIAM. F. PERSONS.
