ANTIGLARE ATTACHMENT FOR HEADLEGH'IS.

Application led February 5, 1925.

To all whom t may conca/Mt:

Be it known that l, ROBERT A; OsUnN, a citizen of the United, States of America, residing` at Birmingham, in the county of Jefferson and State of Alabama, have invented certain new and useful lmprovements in Antiglare Attachments-.for Headlights7 of which the following is a specifieation.

My invention relates to an anti-glare attachment for the headlights Vof automobiles, and consists essentially in a novel means of arranging a small mirror in line with the axis of the reflector and at such an angle as to cause the central or focal Zone of light to be deflected upwardly and thence downwardly so that the more direct or glare producing rays of light will not tend to blind Lil) an appro-aching driver.

More particularly myr present invention is concerned with the provision of a bracket for mounting the reflector on the headlight frame within the headlight, as l show in my pending application, Serial No. 38,371, other means for mounting the reflector on the inner surface of the lens, therefore l have elected to confine the subject matter and the claims of this application to a bracket attached to the headlight frame.

A further object of my invention is to simplify and perfect a means for mounting this light-intercepting and deflecting mirror so that it will not be unattractive in appearance; can be mounted in place without trouble or expense; will not become misplaced in service; and will enable the antiglare attachment to be produced at a relative small expense.

My invention comprises the novel details of construction and arrangement of parts, which in their preferred embodiment only are illustrated in the accompanying drawings which form a part of this specification, and in which z- Fig. 1 is a detail perspective view from the front of my anti-glare attachment.

Fig. 2 is a crosssectional view showing the mirror and .its supports in side elevation and the marginal mounting ring with` its felt pad in cross-section.

Fig. 3 is a reduced vertical cross-sectional view of a typical headlight equipped with my invention.

Fig.4 4 is a detail plan view of the blank from which the mirror bracket is formed.

Serial No. 7,163.

Fig. 5 is a. cross-sectional view on the line 5-5 of Fig. 1.

Similar reference numerals refer to similar parts throughout the drawings.

l show my invention associated with a typical headlight lamp 1, comprising a rellector 2, an electric lamp 3, and a retaining ring l for the lens 5. All of these parts are of standard construction. My device is intended to be applied to such a headlight without requiring any mechanical change in the latter and to this end I provide a mounting ring 6 adapted to fit into the headlight frame between the lamp 3 and the lens and having its marginal edges appropriately cut away at the points 7 so that it will conform to and t in the correspondingly shaped open end of the lamp frame andl be held against rotation by the engagement of the lamp frame with such portions 7. This ring 6 preferably receives a felt lining 8 to prevent rattling, this lining, as shown, being folded so as to lie on both sides of the ring which will thus hold it in position on the ring.

The ring is provided with an internally projecting lug 9 at its top and with two similar lugs 10 and 11 at its bottom. The bracket for supporting the mirror 12 is illustrated in Fig. l, the full lines showing the blank and the dotted lines showing the shaped bracket. krlhe bracket comprises a center plate 13 which conforms to the shape of the mirror, which, as shown, is circular, but the particular shape of the mirror may be changed as desired. This plate 13 is provided with side crimping flanges 14 and a bottom flange 15, which flanges are crimped over the mirror frame or the mirror itself, as may be desired, so as to hold the same in position on the center plate 13 as a backing. The bracket blank has an upper' leg 1G and two different bottoni legs 17 and 18, the several bracket `legs being formed by narrow strips of the sheet metal which are bent down into U-shape, as shown in cross section, Fig. 5, except at their ends 19 which are left flat so that they can be secured by rivets or grommets 20 to the ring projections 9, 10 and 11, thereby mounting the bracket rigidly with the three point sup port on the ring. The lower legs 17 and 18 are bent in a plane inclined outwardly and downwardly at an angle to the upper leg 16 and center plate 13 which results in setting the mirror at an inclination, as shown in Fig. 2. rllhe bracket sets the mirror with its center appropriately in line with the axis ot the reflector and in the path ot the direct rays from the lamp 3 so that the central zone ot' light, in which occurs the brightest light rays, has the opaque mirror set therein so that all such rays are deflected thereby upwardly against the upper zone ot the reflector and thence downwardly towai'ds the ground, 'lhc light rays passing oli marginally about the mirror are not of such character as to produce an objectionable glare and yet at the saine time they enable the full lighting el'i'ect *from the lamp to be obtained with a minimum of light obstruction irom the bracket due to the small size oi the inclined mirror and the thin bracket legs 16, l? and 18. The mirror itseliu does not, in eilect, reduce the lighting eliciency but merely detlects the rays ot light. l thus provide an anti-glare attachment which can be verv cheaply manufactured; which can be installed without requiring tools or skilled labor; which will positively hold its position; and which will not noticeably atleet the lighting eliiciency ot the headlights but will merely intercept and del'lect downwardly such part ot the light rays as now produce the objectionable glare.

Though l have described with great particularit-y the details ol" the embodiment oic the invention herein shown, it is notr to be construed that l am limited thereto, as changes in arrangement and substitution ot equivalents may be made by those skilled in the art without departing from the invention as delined in the appended claims.

Having thus described my invention, what l claim as new and desire to secure by lietters Patent, is

i. in anti-glare attachment for headlights, comprising a bracket having a plurality oi narrow radially disposed supporting legs, marginal means to mount the bracket in the lamp by means of said legs, and means to mount a small mirror on the bracket with an upward inclination and in position to intercept the central Zone or" direct rays from the headlight.

2, An anti-glare attachment for headlights, according to claim l, in which the marginal mounting means lor the bracket comprises a ring adapted to be received in the headlight trame.

3. An anti-glare attachment for headlights, according to claim l, in which the marginal mounting means for the bracket comprises a ring adapted to be received .in and concealed by the headlight frame.

4. An anti-glare attachment for headlights, according -to claim l, in which the mounting means Vtor the b 1acket comprises a ring adapted to be received in the headlight l'rame and having portions thercot adapted to interlock vith the headlight trame to prevent rotation ot' the ring.

5. rlhe combination with a headlight having a reflector, a lens, and a lens retaining ring, ot' a bracket mounting ring adapted to be inserted in the headlight on the inside ci the lens, and having elements adapted to engage the headlight to prevent rotation oi the ring, a bracket having radial narrow divergent legs connected to the ringand adapted to provide a central mirror support near the transverse center ot' the headlight, and means to mount a mirror at an upward inclination on said support.

t3. i headlight according to claim 5, in which the bracket is i'ormed in an integral structure comprising the legs and the central mirror support.

7. ln an anti-glare attachment for headlights, comprising a marginal ring having elements adapted by engagement with the headlight trame to prevent its rotation thereon, a mirror, a mounting bracket tor the mirror having radial narrow legs, and means to connect said legs to said ring.

8. A. headlightattaclnnent accordingl to claim ,7, in which the legs are toi-med by bending narrow strips or' metal integral with the bracket to a U-shape except at their ends where they are adapted to be jointed to the ring.

9. A headlight attachment according to claim 7, in which the ring has internal projections adapted to be overlapped by tlattened ends ot the bracket legs` and means to rigidly rivet said ends of the bracket legs to said projections on the ring.

ln testimony whereof l affix my signature ROBERT A. OSBURN.
