HEADLIGHT EUR. AUTOMOBILES.

Application med November 25, 191e.- serial No.

A"To at@ w/Lom it may concern Be it known that I, vALBERT Mounier, a

Three Oaks, in the countyof Berrien and State of Michigan, have invented a. certain new and useful Improvement in Headlights for Automobiles, of which the following is a specification.

'.My 'inventionrelates to headlights for automobiles and has for its object-to providev convenient. means wherebyy a single headlight may be .'utilized'togive alter nately as required a strong forward vbeam of lighta'nd' a strong 'lateral beam to illuminate the side of the road'when, for any rea?- son, .it is desirable to discontinue theuse of the forward reflecting light. -Of course both of the lights could be simultaneously operated.

'This general object is 'accomplished by -incorporating in vone Land the 'same lamp or two 'or more lamps, the

as lectprs being at an angle to each other.

reflector systemtwo ormore, reflectors and focal lightof the re- I `nave shown my invention somewhat diazically, although-.the structure here ted is in fact taken' from ya Working lampi I have shown the lamp 'arranged with though there Amight 'be grammatic. i So far as thefinvention is illustrated that -illustration is/found in the accompanying ldrawings, wherein Y @Figure l is a diagrammatic view of two lamps supposed to he lplaced in position on opposite sides of the automobile; Y

lFig. 2. is an. enlarged front view o1 Aone of the lam-ps; I i'. "3 is an enlarged rear View of one ofthe lamps;.

A is a reflector adapted to direct the lightforwardly. v L

B is a reflector adapted to throw the light to one side. The reflector A is provided with a centrally disposed lamp C with a suitable base C1, and inleading wire C.

are as follows D is a lamp properly disposed in the re iiector B and'p'rovided with a base D1 and inlefading wires D2. i

PatternedNov.19,1918.A

The reflectorl B is in part placed-in the rear of the reflector A vand-hence to avoid projecting the associate parts too tar toward the rear, it is desirable to place the lamp I) in an inclined position as indicated in F ig. 4, though ofcourse it' can be placed 'as indicated in Fig.' 5. 'In -any eventthis .lamp is'in the rear offthel main' reflector A and in rear of the lamp U ofthat reflector. *i I am not showing in any detailed manner the arrangement of the several parte, nor do I wish to be limitedl to the size, forni,

proportion and arrangement of the parts illustrated, as of course great vari-ations in these could be made. It4 is my purpose to stamp or draw a single reflector into a suitable shape or form and this shape of course' may greatly vary from that shown.

The use and operation o't' my invention Lamps of the character suggested may be mounted each 'on the forward end and at one side ofthe automohile. The main reiiector and lamp are'of such size, shape and characteras to give a beam of light ofrelatively 'great power, and this beam oflight is directed forwardly along the road. Ein

perience shows that a strong beam of lights' is undesirable,where automobilesl are ap'- -proaching each other .from outside directions. If, however, the strong light commonly lused 4be cut oil at the moment when the automobile is about to pass another, e. new danger occurs particularly where traveling on a narrow country road. The dri wishes to drive as nearly as possible on, the edge of the road, or as far from the ap preaching car as possible, and for this purpose the side of the road ought to be illumi- 11a-ted. the arrangement shown, this result can be' accornplished-- The operator canof course, if he desires it, have both lamps, or if there he morethan two Ireflectors and lamps in. a single construction, then all of l his lamps energias at the same time. In

any event when he approaches 'another car he will switch out the main or .forwardly directed lamp or lamps so as to diminish the The secondary" hrilliancy of his headlights. lamp with 'its relectoris energized,A if not, already in action, and its rear iight vice is directed in accordance with its predetermined position. If such secondary reflectorv is toward the inside of the car and at one s'ide of the main reflector and slightly above it, the effect, will be of course to illuminate the edge of the road at the danger line.

The focal lines or axes of thetw'o or more reflectors are for this reason inclined to each other as indicated.

In order that the main reflector 'may not be materially illuminated after its light has been cut off, the secondary reflector is placed back of the main reflector, and its light back of the main reflector, so that no considerable, or at least a 4very much 'reduced reflection proceeds from the main reflector. For `the purpose of utting the headlight ,in the smallest possi lecompass, it is desirable that the lbase and associateparts of the lamp -of the secondary reflector should be placed substantially at right angles and in close proximity to the corresponding parts of the main reflector lamp. Thus the entire headlight 'can be placed in yand supported .by the ordinary casings.

I claim: y i 4v1. A headlight reflector With a secondary reflector situated in its margin and lying entirely w'ithin its periphery, an independent lighting means located Within the secondary reflector andl adapted to operate alone and independently of the'main operating means, said lighting means situated in rear ,of the 4 35 hghtin axes o the -main and secondary reflectors being at an angle one to another, the secondary reflector so situated that when its li ht-.

ing means is loperating alone Ithere wil be' means of the lmain reflector, the

no reflection of that lighting means from the main reflector.

2. A headlight for vehicles and the like comprising a main parabolic reflector', a source of light at the focus thereof, 'an auxiliary parabolic reflector integralfwith the main reflector' having its reflecting-surA face partially at oneside of and :partially at the rear ol the main reflector, the light source at the focus of the auxiliary reflector, the axes of the two reflectors being' inclined one to another, the reflectors being so positioned that light from the source in the aux iliary reflector cannot be reflected from the main reflector and light from the` main source cannot be reflected directly from'the auxiliary reflector;

3. A headlight containing a main reflector and an auxiliary reflector' inset Within its side and integral with it, an independent.

source of light in each reflector, the two reflectors being so-positioned that the auxf iliary source of light cannot be reflected from the main reflector.l

4. In a headlight a main reflector a4 source of light therefor an auxiliary reflector inset Within the side of the main reflector, said auxiliary reflectorso positioned that li ht from the main source of' light cannot e reflected.l from it.

In testimony whereof I alix mysignature, in the presence of two Witnesses, this 17th day of November, 1916.
