NEW ERSEY, SSGNOR TO AMERECIAN GASACCUMULATOR COMPANY, F ELIZABETH, NEW JERSEY, A CGRPORATUN 0F NEW JERSEY UUMBINAT-IGN LAMP AND REFLEGTOFJ .application filed September 10, 1929. Serial No; 391,586..

My invention relates to combination lamp and redector. devices which are adapted for use upon automobiles and other like veh1cular traflic and are of especial advantage when embodied in a structure comprising a reilector of the type known as self-focusing7 reflectors. f

rlhe general object of the invention is to provide means of novel construction and of "i0 convenient character for supporting an electric light in co-operative relation to the rev tlecting surface of the reflector.

To the foregoing and other ends my invention comprehends the construction as hereinafter described in detail, particularly 3 invention, the said View being taken in a plane co-incident or parallel with the central axis of the reflector;

Fig. 2 is a view in front elevation; Fig. 3 is a view in rear elevation of th lamp structure with the inclosing rear casing shown in Fig. l removed;

Fig. 4 is a view in horizontal section taken on the line 4-4 of Fig. 1;

Fig. 5 is a view in front elevation of the reflector with the electric light mounted therein, other portions of the structure shown in lpreceding figures or' the drawings being removed; and

Fig. 6 is a sectional view showing the means by which the electric light holder or socket is supported.

ln the drawings l designates a reflector which in the construction shown is of central triple type comprising three reecting surfaces arranged in right angular or approximately right angular relation to each other. l desire to note, however, that my invention is not limited necessarily to a constructionv of reector ot the particular type mentioned. rlfhe sides of the reflector terminate at their outer edges in edges 2, oi arcuate shape which are integral with and merge into the circular outer portion 3 of the reflector structure. By reason of the fact that the outer edges of the reflectors are curved, as indicated at 2, spaces such as indicated at 5 in Figs. l, 2 and l are provided between the outer edges of adjoining sides of the reflector. The spaces 5, as will be apparent from Fig. 4, are of general triangular shape and in one of them an opening l0 is provided within -which is located a holder or socket member ll having a bayonet slot l2 for engaging and holding an electric light 13. rllhe holder or socket member 1l is supported by the fingers lll.. The holder or socket member l1 entends into the interior of the reflector -and its outer end is located between the lingers lll and is connected thereto by soldering or otherwise as may be preferred. rlhese fingers la are integral with and project from the opposite ends of a base portion 15 which is secured by welding or otherwise to the laterally and outwardly extending flange 16 provided Iat the front or outer edge of the reflector.

A plate or" glass or other suitable equivalent material 20 is mounted upon the Tdange 16 of the reflector, being seated against a washer 21 of suitable material which serves not only as a cushioning means but also asa means for concealing the joint between the plate 2O and the lange 16. The plate 20 may or may not have means specially provided for edecting di'usion of the light rays which emerge from the device. The rays which emerge from the device are those which may radiate from the electric light 13 and also those which may radiate from a distant source and which may impinge upon the reflecting surface of' the redector and be reflected back through the said plate.

Any convenient and suitable means may be provided for retaining the plate 20 in position upon the ange 16. rlhe means employed bv me for that purpose comprises an annular sheet metal member 25 the outer edge portion of which is curvilinear in cross section and the inner edge of which portion extends inwardly as indicated at 26 Iand. contacts with the outer side of the plate 20 in adjoining relation to the outer edge there` of. The outer side of the member 25 extends rearwardly outside of and beyond the outer edge of the plate 20 and its inner edge is bent inwardly, as indicated, to form a shoulder 27. A rearcover and protecting casing 30 is provided which may be described broadly as of cone shape. Its front edge portion is bent inwardly, -as indicated at 31, to provide an annular shoulder 32 a ainst which the rear edge of the rearward y extending outer portion of the member 25 may contact. A bent narrow metal strip member 35 is provided intermediate the protecting casing 30 and the reflector 1 and has at its opposite ends outwardly and rearwardly bent portions 36 the Arear ends of which contact with the shoulder 27 as indicated at 37.

For the purpose offastening the protecting casing 30 in position to protect the rear side` of the reflector 1 I have provided a fastening bolt 38 which extends through 'an opening provided in the central part of the rear end of the casing 30, the inner end of which bolt is screw-threaded and has screwthreaded connection with an opening .inthe metal strip member 35 as indicated at 39. B screwing the bolt 38 inwardly the front e ge portion of the protecting casing`30 is caused to move toward the front inside rear edge portion of the annular member 25.

For holding the reflector, the annular member 25V and the plate 2O in assembled relation I- have provided the springs 40 which are secured by means of rivets 41 to the opposite sides of the member 35. The opposite ends of these springs extend in opposite directions `transversely of the member 35 and are bent forwardly as shown in Fig. e with their opposite ends in contact with four points upon the rear side of the flange 16 of the reflector. It will be apparent, therefore, that the springs 40 which are connected at their central points to the strip member 35 and contact at their outer ends with the flange of the reflector l tend to cause separation of the reflector and the said strip 35; but the opposite ends of the latter are in engagement with the shoulder 37 at the rear edge of the member 25 in consequence of which the said reflector and the member 25 act to yieldingly hold the plate 20 in position between the inner edge 26 of the member 25 and the opposing flange of the reflector l.

Electric current is supplied by means of the conductor 42 tothe filament of the electric light 13 to render the same incandescent and therefore light-emitting.

` It will be. seen that by my invention I have provided means for supporting an electricYA light, which means is located in a portion of the reflector structure which is without utility for light reflecting purposes. The presence of the opening in one of the triangular portions 5, as shown and described, does not operate to remove or reduce any portion of the area of the lreflecting surface of the reflector.

Although, as I have heretofore indicated, my invention may be embodied in a struc- ,ture including a reflector of different construction from. that shown yet a reflector of the characterv shown is particularly well adapted for use in the construction of a device embodying the invention because it provides means whereby the support for the light may be provided without removing any portion of the structure including a light reflecting surface. j

Having thus described my invention, what I claim and desire to )secure by Letters Patent is; v 1. A combination lamp and reflector device comprising a hollow reflector having light reflecting surfaces upon its inner side arranged in right' angular relation to each other, the outer edges of which surfaces are curved, and the said reflector having portions circular in cross section locatedbetween the outer edges of adjoining reflector surfaces, one of the said circular portions having an opening therethrough, a lamp socket located in said opening, and means for supporting said socket in said opening.

2. A combination lamp and reflector device comprising a reflector having reflector surfaces arranged in right angular and convergent relation with respect to each other, the outer edges of the said surfaces being curved, and the said reflector having triangular portions located between the outer edges of adjoining reflecting surfaces, one of the said triangular portions being provided with an opening therethrough, an electric lamp socket member located in said opening, fingers mounted upon a part of the said reflector in spaced relation to each other and being l( cated-on opposite sides of a portion of said socket member, and means for securing said fingers to said socket member.

3. A combination lamp and reflector device comprising a hollow` reflector, the sides of said reflector being in right angular and in convergent relation to each other and the outer edges of said sides being curved and the said reflector comprising at its front end a circular portion into which the outer edges of the said sides merge, the said circular portion including triangular portions located between the outer edges of adjoining sides and one of the said triangular portions having an opening therethrough, a light holding socket member located in said opening and means for supporting the said socket member within said opening.

4. A combination lamp and reflector device comprising a hollow reflector, the sides of which are in right angular and conver ent relation to each other and the outer e ges of said sides being'curved and the said reflector comprising at its front end a circular portion into which the outer edges of the said sides merge, the said circular portion including triangular portions located between the outer edges of adjoining sides and one of the said triangular portions havingan opening therethrough, a light holding socket member located in said opening, means located outside of said reflector in adjoining relation to said openingl for supporting the said socket member, andmeans for securing the said last named means to the said socket member.

5. A combination lamp and reflector device comprising a hollow reflector, the front end of which is open, the sides of said reflector being in right angular and in convergent relation to each other and the outer edges of said sides being curved and the said reflector comprising at its front end a circular portion into which the outer edges of said sides merge, the said circular portion having at its front edge an outwardly extending flange and including triangular portions located between the outer edges of adjoining sides and one of said triangular portions having an opening therethrough, a light holding socket member located in said opening, means for supporting said light holding socket member, said means being secured to the said flange and being located outside of the said reflector in adjoining relation to the said opening, and means for securing the said light holding socket member to the said last mentioned means.

In testimony that I claim the foregoing as my invention, I have hereunto signed my name this 5th day of September, A. D. 1929.`
