AUTOMOBILE HEADLIGHT.

Application filed February This invention relates to automobile head lights and particularly pertains to a socket holder therefor.

It is the principal object of my present invention to generally improve the construction of automobile headlights by providing them with improved socket holding mechanism permitting the socket and bulb to be easily and quickly removed from the headlight for replacements or repairs without the necessity of removing the lens from the headlight. v

In carrying out this object into practice I form an aperture centrally at the rear of the headlight casing and in the reflector. Projecting within these apertures is a socket holder which is ren'iovably held in place by a retaining means located cxteriorly of the headlight casing so that the socket holder may be inserted. or removed from the headlight as desired.

One form which the invention may assume is exemplified in the following description and illustrated by way of example in the accompanying drawings in which:

Fig. 1 is a fragmentary view in Side elevation 01 a headlight embodying the preferred form of my invention with certain of the parts shown in section to more fully disclose certain details of construction.

Fig. 2 is a plan section of my improved device disclosing its construction and the manner in which it is applied to a headlight.

Referring more particularly to the accompanying drawings 1 show a headlight 10 of the parabolic or drum type having an outer shell 11 and an interiorly located reflector 12. At the rear of the headlight and centrally thereof, the shell 11 and the reflector 12 are each formed with a circular aperture 14-. Arranged within the aperture is of the shell and projecting outwardly therefrom is a retaining sleeve 1.5 which is formed with a circumscribing flange 16 which overlaps the marginal edge of the aperture 14. This flange 16 is located interiorly of the shell. 11 and abuts against its interior surface as shown in Fig. 2. A series of rivets 17 firmly connect the sleeve 16 to the shell 11 with the.

sleeve disposed concentric in respectto the axis of the shell. The sleeve 15 projects outwardly through the aperture 14 as shown in the drawings and is exteriorly threaded to receive a retaining nut 18.

For cooperation with the sleeve 15 I provide a socket holder 19 which is adapted to headlights may be constructed in an inexi, 1926. Serial No. 85,839.-

project inwardly through the sleeve 15 and the apertures 1 1 in the shell and reflector. The outer end of this socket holder 19 is formed with a concentric flange 20 which is shouldered as shown in Fig. 2, so that it will nest within the outer end of the sleeve 15 and abut thereagainst. The retaining nut 18 acts to clamp the flange 20 against the end of the sleeve 15, thus holding the socket holder firmly in concentric relation to the sleeve 15 and consequently the headlight shell 11 and its reflector 12.

The socket holder 19 is formed with a longitudinal slot 21 through which a radial projection 22 of the socket 23 may project. This projection 22 is adapted to threadedly receive an adjusting screw 21 which extends through an opening 25 in the flange 20. By adjusting this screw 24; the socket may be longitudinally adjusted within the socket holder 19. The socket 23 is adapted to receive a light bulb 26.

To insure that the socket holder 19 will always be returned to its proper position relative to the sleeve and headlight, it is fitted with a dowel pin 27 which engages a notch on the interior surface of the sleeve 15.

To remove the socket and bulb for replacements or repairs it is only necessary to remove the retaining nut 18 from the sleeve 15. The socket holder 19 together with the socket and bulb may then be withdrawn through the apertures 14. in theshell and reflector and through the sleeve 15. The replacements or repairs may then be made and the socket holder again projected through the sleeve 15 and the apertures 14, after which the retaining nut is re-engaged with the sleeve 15 and tightened thereon to clamp the flange 20 firmly against the outer end of the sleeve 15.

It is obvious that by my present invention,

pensive manner permitting the socket and bulb to be easily and quickly removed for replacements or repairs, without the necessity of removing the headlight lens.

I desire to point out that headlights now in use may be equipped with devices embodying my invention by simply cutting the apertures 14: in the shell and reflector and riveting the sleeve 15 to the shell in proper concentric relation to the headlight. The socket holder 19 and nut 18 may then be applied as described.

WV'hile I have shown the preferred for-mot my invention, it is to be understood. that various changes in its construction may be made Without departing from the spirit of the invention, as defined in the appended claim.

Having thus described my invention, What I claim and desire to secure by Letters Patent is:

In combination, a headlight having an aperture formed through its rear Wall, a sleeve-like member projecting outwardly through said aperture, a flange surrounding the inner end of said member and secured to the headlight about the perimeter of said aperture, the outer end of said sleeve being exteriorly threaded, a socket receiving member dispo3ed concentric with relation to the sleeve-like member and projecting inwardly therethrough toward the interior of the headlight, a flange formed about the outer end of said socket receiving member, said flange being of a diameter substantially agreeing with the outer diameter of the sleeve, at its inner end the outer periphery of said flange being reduced so that it Will nest Within the outer end of the sleeve and its enlarged portion abut against the outer end thereof, a clamping nut formed with an enlarged aperture in alignment With the aperture in the sleeve, said clamping nut threadedl engaging the sleeve and abutting against t e flange 0n the socket receiving member to clamp the latter to the sleeve, a socket reciprocably mounted in the inner end of said socket receiving member, at one side said socket receiving member being formed with a longitudinal slot, a radial projection on said socket projecting outwardly through said slot, an adjusting screw inserted through the flange in the socket receiving member eX- teriorly and parallel to the socket receiving a portion of said member and threadedly engaging said radial pro ection on the socket,

spring interposed between said radial pro-- jection and socket and the inner face of the flange on the socket receiving member Whereby rotating movement of the screw will advance or retract the socket toward and away from the flange. GEORGE RODRIGUES.
