' Application led December 27, 19126. ASerial No. 157,296.

A further object is to provide a headlight in whichV the light is so projected that it -is of a non-glaring quality, thereby making it unnecessary to dim the light when passmg approaching vehicles.

A further obj lt is to provide a headlight in which novel means is employed for adjustin the reflection of .the light to any desire angle. i f* Other objects and advantages will appear inthe following specification, and the novel features of the invention will be particularly pointed out in the 'appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which j ,Y y

Figure 1 is a front elevation of my device,

Figure 2 is a sectional view along the line 2-2 of Figure 1,

Figure 3 is a sectional view along the line 33 of Fi re 2,

Figure 4 1s a sectional view along the line 4--4 of Figure 2,

Figure 5 is a detail view taken along the line 5-5 of Figure 2, and.

Figure 6 is a detall vlew along the line 6-6 of Figure 2.

In carrying out my invention, I make 'use of metal outer casing 1 having a removable cover portion 2, and a slantin front end 2.

The cover portion 2 is secure to the casing 1 by means of suitable spring members 3'. The casing 1 is secured to the frame of the car bymeans of a base 4. Thebase 4, as will be noted from Figure 2, is provided with a convex bottom 5 having a relatively large opening 6 therein. A washer 7 having the same curvature as the bottom 5 is placed underneath the bottom 5 and adjacent the frame of the car. A similar washer 8 is placed upon the top surface of the bottom 5. A bolt 9 whichis secured to the frame of the car extends through the washers 7 and 8. The relatively large opening 6 inthe bottom of the base permits the headlight to be ad .in a certain portion o justed to any desired angle with 4respect to the-car. One side of the base'4 is provided FFECE.' y

with an opening 10 so that a nut 11 on one I end of the bolt 9 can be reached. In tightening the nut 11 the bottom 45 of the casing 4 is firmly retained between the washers 7 and 8.

pair of

reflectors

12 and 13 is mounted withm the casing 1. 'The reector 12 is parabolic in cross section, as shown in Figure 2, and therefore has the property of projecting .light to a relatively long distance .ahead of the vehicle. AAn incandescent electric bulb 14 is mounted in the reflector 12. The reflector 12 is supported within the casing 1 by meansof a crossbar 15 which extends fromv side to side of the casing 1.

'.1he crossbar is provided with a bolt 16 havmg a nut 17 on one end and a ball bearing 18 on the other end. The ball 18 is retained by a socket 19 in one end of a supporting member' 2O which is secured to the reflector 12. It will therefore be seen that the reflector.12 can be adjusted to any required an le.

The re ector 13, as will be seen from Figure 2, is of a relatively shallow type and ispositioned near the front of the casing 1.

-The reflector 13 is -supported by a ball and socket connection of the same construction as that used in supporting the reflector 12,

and therefore requires'no detailed descripi tion. The reflector y13 is also provided with an incandescent electric bulb 21. Both 'of the bulbs 14 and 21 are connected by means of conductor wires 22 to a storage battery,`

not shown, such asis usually carried in motor vehicles.

Looking now at Figure 3 it will be seen thatl two sides of the reflector 13- are vcut away, thereby forming fiat surfaces 23,

whose purpose will be explained later. The' reflector 13 is further provided with an opening 24in the top for the urpose of permitting a lcertain amount o light to pass out and into the interior of. the casing 1..

' An inner metal casin the casing 1. The interior surface of the inner casing is provided l with a coating of material for re- 25 is disposed withe liecting light .suoli as nickel or silver plate.

The innericasing 25 fits snugl within `the outer casing 1 and is secure means of rivets 26, or other suitable fastening means. The rear end. 26 .of the inner casing is provided with an `opening 27 v thereto-by as shownin Figure 6.l The purpose of this corrugated surface is to cause the lightwhich is reflected therefrom to be spread out andV projected in a 4 flat beam below the range of vision of the driver of the oncoming car.

A portion of the inner casing is tapered as shown inFigures 3 and 4. .

Lines

28 and 29 in Figure 2 indicate the extent of this tapered portion. It has been found that a better distribution of light and less glare is obtained yby the use of this tapered port-ion.

A deflcctor 30 is disposed within the casing 25. As shown in Figures 4 and' 5, the ed es of the deflector 30 are bent upwardly anA pivotally secured to the inner casing 25 by means of rivets 31. The deflector is madel from'material such as that used in the inner casing 25 and is. also provided with a coating for reflecting light. The deflectQr is furtlrer .provided with corrugations similar to those in the top portion of the inner casing 5. Dotted lines 32 in Figure 2 indicate the flat beam of light reflected from the deflector 30,

`while dotted lines 33 indicate the flat beam of light reflected'from the corrugated portion o the inner casing. l

Referring now to Figure 2, it will be observed that the deflector 30 is provided with a bent back portion 34. A coil spring 35 is disposed between the portion 34 and the inner casing 25. A bolt 36 is disposed with' in the spring 35 and extends through the in,- ner casing 25. The other end is threaded and screws into a threaded opening in the deflector 30.l The deflector 30 may be adjusted to different angles by means of the -horizontalfflutings as indicated generally at 39. That portion ofthe glass between the vletters z-a is clear so as to offer as little resistance as possible to the light reflected from the deflector 30 and t-he corrugated top portion of the inner casing 25. v

A colored lass 40 isdisposed on.one side of the head-light. The color may be ofa'ny desired shade. This glass is exposed to the reflected light from the reflector 12 and also the lightr assing out through the opening 24 in the re ector 13.v This'side glass provides a convenient means for indicating the direction in which cars are traveling, especially at street intersections, and also gwes some indication of the speed at -which such cars are traveling -the reflector 12 ina conical beam.

noemer From the foregoing description of the va-` r1ous parts of the device, the operation thereof maybe readily understood. My headlight is designed to be used in pairsand is positioncdon the car in the same manner as the ordinary type of light. Switches are vided for 1lluminating the bulbs 14 an 21 separately or simultaneously. While driving Vin the country it is intended that both bulbs shall be illuminated. Light which is projected from the bulb 14 is reflected from As will be seen from Figure 2, the reflector 12 is. disposed at such an angle as to reflect the light upwardly against the deflector 30A and the top portion of the inner casing 25. The

light which strikes the corrugated deflector 30 is reflected forwardly in a flat beam, as indicated by dotted lines 33 in Figure 2, and the light which strikes the` corrugated top portion of the inner casing is reflected in a flat beam as indicated by dotted lines 33 in Fi ure 2. The result is that a flat beam of lig t is projected far in advance of the car, and at the same time projected below the line of vision of the driver of the approaching car. For I`this reason it is unnecessar to dim the light when passing a-pproac ing cars, as there is no danger of the light blinding the driver of the approaching car.

It will be observed that since the reflector 13 is of a shallow type the light reflected therefrom will be projected in a broad beam, thereby illuminating lthe crown and sides of the road near the car. The frosted portion of the glass 38 which isl directely in front loo of the reflector 13 destroys all glare caused tor disposed between the reflector vand said glass front, said reflector being arranged to project light to a. distance relatively near the `headlight, an innercasing disposed within said casing, said inner casing having corrugations and arranged vto reflect light, a reflector disposed near the rear end of said first named casing and partially encased by `said inner casing, said second named reflector having a source of light disposed in front thereof and arranged to project a beam of light against said corrugations, whereby the beam of light is reflected to a distance relatively far from the car.
