To all whom it may concern:

Be it known that I, WmLrAM F. ANKLAM, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of "Michigan, have invented cert'ain new and useful Improvements in Headlights, ofwhich the following is'a specificstion, reference sing had therein to; the accompanyingdrewings.

This invention relates to headlights and refers more particularly to a new and improved construction of headlight adapted for use on automobiles or the like.

Among the objects of the invention are to provide a structure whereby an inverted light efi'ect can be obtained in headlight constructions, thus preventing the blinding glare usually produced by headlights having refiectors; to provide a construction in wine the deflector is located in front of end ccn trelly-positioned with reference to the lamp bulb; to utilize the lamp bulb as a mounting means for the deflector; to provide means wherebythe deflector is adjustebly supported with respect to the bulb and the reflector; to provide means whereby the deflector can i be adjusted toward or from the reflector in dependent of the adjustment of .the bulb with reference to the reflector; to provide a.

construction in which the light can be focused by adjustment of the deflector alone; and in general to provide a new and improved construction of the character above referred to.

In the drawings:

Figure 1 is a vertical sectional. view through an automobile headlight embodying my invention;

Fig. 2 is a detailed view of the adjusting bolt detached;

Fig.1. 3 is an end view oi-the head of the edjusting bolt;

- ably mounted in Fig. 4 IS an end view of the nut carried by the adjusting: bolt;

Fig. 5 is a detail view of the defies-torcarrving shell.

Describing in detail the particular embodiment of my invention shown in the -drawings, designates the reflector of an automobile headlight, B the lens and (l the electric light bulb having one end 1) adjust the seat E provided at the rear end of the casing. A suitable lead wire G is provided for conducting the current to the bulb.

Various attempts have mode in proso arranged that its head K inp: J and the nut L serves in close contact.

give an Inverted light eiiect, while pernnt---' ting; proper focusing of the light.

n detail this arrangement comprises 2t deflector H. edjustabliy mounted upon the end I of the bulb. As 1%. the end 1 shown in Fig.

the glare ifrem the of the bulb extends within e. metal casing J, e

which is aperturcd at J to permit the insertion of the adjusting bolt K the letter being is located with in the metal casing J. As shown in deteil in Figs. 2 end 3, the head K of the adjusting bolt is serrated to provide projections The space within the metal casing J is filled with cement which when set will. pro vent the turning of the adjusting bolt. For more securely mstening the metal casing J to the end I of the bulb, the letter is preferably provided with projections I which interlock into the cement. v

Telescopicclly mounted upon the metal casing J is ashell M which carries the defleetorplcte H. "Within the shell M is positinned a nut L having it screw threaded en gegement with the bolt K, this not L being 'shell and deflector plate toward or from the center of the bulb. A sprrnp P sleeved upon the bolt ill: and acting: against the metal costo hold the parts After the shell M and dc-- been adjusted to proptlector plate have can be locked in erly focus the light they this position by tightening up the cap nut Q.

description it will be ohthe light een be the deflector From the above vions that the focusing of accomplished by adjustment of plate clone, or if adjustment of the bulb is made at the opposite end the deflector plate can be adjusted to compensate for any relative change in position between the source of light and the reflector. I'l hilo l have shown the deflector as formed in the segment oi e circle the invention is not limited to this particular construction, and var ous other located in front of changes in the details of construction end arrangements and combinations of parts can be made within the scope of my invention.

The invention also resides I construction of a bulb having a base on both ends, one end being provided with a lead wire and contact necessary to conduct carry the current to the filament, and the opposite end or base being formed without a contact or lead wire.

What I claim as my invention is:

1. The combination with e headlight including a bulb and e reflector, of e deflector located in front of and carried by the bulb and means for adjusting the deflector to focus the light from the bulb withv reference to the reflector.

2. The combination with e headlight including a bulb and a reflector, of a deflector and carried by the bulb,

Gopies of this potent may be obtained for live'cents each by Weshingtonfl in the novel spring; exerting piBSSEJlXS upon the deflector outwardly from the bulb; and on abutment for said spring" connected to said deflector and adjustable to Very its distance from bulb. w

3. The combination with a, headlight ineluding a bniband e reflector, said bulb how ing' securing members on its opposite ends by one of which it is mounted in said 1 fiectoi telescopic members one of which is secured to the other securing member of the bulb, said members being relatively axially adjustable, a spring within the outer teiescoping member beering'at one end thereupon and at the other upon the inner ofseicl members,end a deflector mounted upon the outer telescoping member.

In testimony whereof I eflix my signature V/liLlfiAM F. ANKlLAl /ZL
