This invention relates to bulb mounts for headlights and more especially to'headlights employed on automobiles where under the 7 existing laws of most States a non-glaring beapli of light is required when driving at nig t. V

An object of my invention is the provision of an improved bulbmounting that may be employed in the conventional headlight without in any manner modifying the present con V Figure 1 is a front view of a conventional headlight casing with the lens'thereof broken away disclosing our improved bulb mounting 1 arranged therein.

Figure 2 is a rear elevation of same show ing the electrical connections beteween the bulb sockets. V i v Figure 3 is a side elevation in partialsec-' tion showing the construction of one of the socket units.

Figure 4 represents a diagrammaticview showing the parallel connection of the lamp.

In the drawings like numerals designate like parts. A bulb mounting shell A of sub stantially frusto-conical formation is provided with radially extending socket tubes 1. These socket tubes have their outer rim plane in co-planar relation with the annular inclined side walls 2 of the'shell. The front wall 3 of the shell is providedwith a similar socket tube 1 located centrally of the front wall and projecting inwardly therefrom. The socket tube 1 is provided with an elongated plug 7 having depressible contacts 14 and 15 respectively at each end thereof. The

elongated plug is arranged in the socket tube 1 and proje ts a substantial distance bey nd theplane of the rim of the .frusto-con-ical' shell; This. projected portion of. the plug is for insert'ion within'theflbulb' socket of the conventional headlight. The central socket tube isadapted toreceive the usual headlight bulb 'but which may if desirable, be ofa larger design to i assist more icompletely in diffusing the light rays tisjsuingr from the other, bulbs. l. l

The socket: ma [1 me sura le a5 slots v4 with jwhich 'thle. stud on] thelconventional bulb,5- coacts for securing the latter inele'c tric'al contact: with the depressible contact pin'6, An insulating plug Z isfirmlyins'er'ted at the inner end of the socket tube 1 and ,is

provided with-a centrally "located "bore I through whichthe contact "pin 6is slidable. I

This bore communicates with an enlarged recess, which is clearly shown in Figure 3,

and which is. provided with a bushing 8 to V act asa guideway for a coilspring 9. This colledspring is disposed about the contact pin 6 and hasone end thereof bearing against the floor of the enlarged recess, while the opposite end of the spring bears against an enlarged head 10 on the contact pin. If desired, the Washer 11 may be disposed between the spring and the enlarged head to insure against any possibleslipping of the spring over the head. A stop nut 12 is threaded on the opposite end of. the contact pin to limit the inward movement of same.

By referring to Figure 3, it"will be seen that current from the storage battery or generator of the vehicle will pass fromthe usual lamp casing socket through the spring sustained pin 15' to the lamp in the socketl,

5, while the opposite sides of thelamps 5, as well as the lamp in the socket l is grounded tofthe'shell 3;. Should one of the lamps burn out, the other will not be affected thereby.

' It will be seenthat our improved mountingmay besiinply inserted within the socket of a conventional headlight without in any way .weiclaim asnew is a 4 1-; In a bulb-moun i or au om bil'eheact also passing to one side ofeach of the lamps lights,a frusto-conical shaped shell, a plurality of socket members projecting radially from the side Wall thereof, one end of said shell being closed to provide a front Wall, a
