I HEADLIGHT.

To all whom it may concern Be it known that I,,RoBnRr H. KAISER, a

citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Headlights; and I do hereby declare the following to a full, clear, and exact description of the 1nvent1on, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to automobile headlights.

The object of the invention 1s to provide a headlight for automobiles whlch, whlle diffusing a bright light over a large area, avoids any glare which will blind thedrivers of approaching cars. The 1nvent1on 1s based upon the principle of indirect llghting, but utilizes practically the same amount of reflecting or radiating surface as is at present customary in automobile headlights.

A further object of the invention is to provide such a structure which 1s not only capable of inexpensive embodiment into a new headlight, but can also be manufactured as an attachment for headlights already in use.

With the above objects in view, and such others relating to the details of construction, as may hereinafter appear, my 1nvent1on WillIlOW' be full set forth and described, reference being ad to the accompanying drawings.

In the drawin s:- Figure l is a rent elevation of a lamp, Fig. 2 is a longitudinal section therethrough,

, Fig. 3 is a rear elevation of a lamp sup- P Fig. 4 is an enlarged transverse section therethrough,

Fig. 5 is a perspective view of an annular 10b6, i g Fig. 6 is a detail fragmentary elevation showing the manner in which the lamp support and lamp casing are connected,

Fig. 7 is a section through a modlfied form of the invention, and

Fig. 8 is a fragmentary detailview thereof. I

Referring more particularly to the drawings, 1 represents ashell casing formed in accordance with the accepted forms of automobile headlights, said casing having the side brackets 2 into which the standards of device is constructed as Speciflcation of Letters Patent; Patented May 13, 1919. Application filed November 27, 1917. Serial No. 204,208.

a lamp support may be inserted. Also, the

position. The flanged ring 3 also provides a stop for an annular base 6 which carries n plurality of lam sockets 7 within which the lamps 8 are inserted. The annulus or base 6 is preferably ahollow metal structure into one of whose faces the sockets 7 are recessed, so that the lamps 8 project beyond the face of the annulus only to the extent of the bulb portions thereof. The several sockets 7, wh1ch are arranged in number according to the power of the searchlight to be constructed, are wired together at the rear of the annulus, the connecting wires being then collected into a cord" 9 which may be incased in the conduit 3. The annulus 6 is hinged to the rim of the casing 1, preferably at the lower side of the latterso that the annulus may be swung downwardly and outits closed position.

8, the latter are covered with a circular globe 11 whose edges conform to the innerand outer edges of the annulus 6, and is held thereonby means of clips 12 carried by the annulus. The globe 11 isalso made of translucent material, such as milk white glass. The annulus or base 6 is covered, in its closed position, by means of a closure plate 13 of suitable design, the closure 13 having a lens inserted into an aperture 14 therein and being hinged to the shell 1 and being mounted upon the shell in hinged relation after the manner of the usual an automobile headlight.

In the form shown in Figs. 7 and 8, the an. attachment for In its essential headlights already in use.

base or annulus particulars relatingto the lens frame of" provides a means for locking properly diffuse ,the light 6, the structure is the same as that described .inthe first form, but the shell is in the form of a comparatively wide collar which ma be slipped over the body or shell of .an ordinary headlight, from the rear thereof, the

I flector, an annular lamp edge and of a suitable distance the annulus or base 6 gvith its lamps and globe, is inserted into the front end of the collar until it rests against the ring 5, after which the.

cover or closure 13 is placed in position. The lights, when lighted, throw their rays against the reflector ofthe headlight, from whence they are transmitted in diffused relation on the roadway.

It will be apparent from the foregoing description that the headlight which I have devised constitutes a very simple and inexpensive construction which will throw a -highly diffused light upon a roadway with no glare or other dangerous or in]urious characteristics. Furthermore, the device is capable of instalment upon automobile lamps already in use, as well as in new lamps, the essential feature of the structure consisting'in the proper arrangement of the annulus 6 with its plurality of lamps, within the shell so that the light will be transmitted first to the rear in diffused relation, and then reflected forwardly onto the road.

What I claim as m invention is 1. An electric hea light comprising a casing having an annular mouth, an attaching ring in the mouth of the casing having its peripheral portion engaged within the periphery of said casing, the inner portion of the ring being inwardly offset, aboWl-shaped reflector having its mouth portion disposed,

about and secured on the inwardly offset portion of the rings, an annular lamp base seated in the outer portion of the ring and lamps carried by the inner side of said base.

2.. Anelectric headlight comprisin a rebase mem er secured at the mouth portion of the reflector and having its inner diameter substantially less than the diameter of said mouth portion 1,aos,saa

member shields the lamps from view at the front of the headlight, and a translucent shield for said lamps comprising an annular body of channeled cross-section and having its edge portions secured at the edge portions of the inner face of the lamp base.

4-. An electric headlight comprising a bowl-shaped shell, a bowl-shaped reflector of translucent light diifusing material disposed within the shell and spaced from the walls thereof, a plurality of lamps disposed within the mouth portion of the shell, means for shielding the lamps from view at the front of the shell and translucent light'diffusin coverin for said lamps.

. 5. n electric headlight comprising a shell havin an annular mouth portion, a bowl-shape reflector in said mouth portion, an annular light base and shield member hingedly connected with the shell and movable to lie within the mouth portion thereof, and a series of lamps mounted on the inner face of said member.

6. In a lamp of the class described, the combination of an outer-shell, a reflector contained therein, an annular channeled frame piecesecured to the forward end of the shell, and an annular series of electric lamps positioned Within said channeled frame piece, the latter serving to prevent the rays from said lamps from passing directly through the front of the lamp casing.

In testimony whereof, I aflix my signature in the presence of two witnesses.
