WILLIAM F. PERSONS, OF LAKEWOOD, OHIO, ASSIGNOR TO THE GUIDE MOTOR LAMP MANUFACTURING COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

AUTOMOBILE-LAMP.

To all whom it may concern Beit known that I, VJLLIAM l Prnsoxs, a citizen of the United States, rosidin at Lakewood, in the county of Cuyahoga and State of Ohio, have invented a (:ertainnew and useful Improvement in luatoinohilw Lamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

19 This invention relates generally to vehiole lamps, and more particularly to one intended for use upon automobiles \vehieles.

One object of the invention is; to provide anexeeedingly simple and highly eilieient means for retaining the glass front or lens in the body oi the lamp and another object is to provide a simple and eilieient means for shifting the focus of the light whereby the intensity thereof can be regulated as desired. I

\Vith these objects and certain others "whieh' will become apparent as the description proeeeds, the inventioneoneists in the novel features of construction, COIXll'JlImtlOll and arrangement, all of which will be fully described, hereinafter and set forth in the appended claims.

Inthe drawing forming a. part of this spee'ifictition Figure 1 is a. vertical sectional view of an automobile lamp constructed in accordancewith and embodying my inven-- tion; Fig. .2 is a detail view ofthe light shifting menus; Fig. 3 isa detail perspee :satjveviewof 'the'split or divided retaining nag; and .Fig. 4 a detail seetional elevation illustrating the overlapped ends of said .ring when inoperative or looking position.

In the practieal embodiment of my inveni 40 tion, .I employ alam'p body 10, preferably of :sheet metal, and represented. as of a torpe'do shape, ,butit will be understood that helamp body 'can he made in any preferred iitable design.

' v. fllllarthe frontthe body is given a slight inwardoilrve as indicated at ll and then shouldered gasshown at 1 2,1 and the 'extf-"QmQ outer end is rolled over asshoWn at -.1 his rol led over portion being substanequal to one half a oirele in'order that 'th'ef extremeforwa'ml edge thereof may extend sufficiently inwardly to provide a firm, "2. :senton-bearing, for the inwardly extending l-port'ion Ofmtll reta-inii'ig ring hereafter some inlly described, v I

Specification of Letters Patent.

and motor Patented Feb. 6, 1917.

The reflector '1 -41 iits Within the-body oi? the lamp and is made upon a paraiholie eurve in order to secure the best results as a rellm-ting niodiuin. and this reflector PEUYlllQ-ll. with an outwardly eixteinling rim .15 Wllllll rests upon the interior shoulder. 11. and. thereby positions the reflector within the body of the lamp. said, reflector having a central opening for the sol'ihet of the lamp ill; and when needed, the rellm'tor can hare an additional openingfor the Siouket ol the supplemental lamp l7.

li desired, a slight head 18 may be pro duced at the juncture oi the irel'lector and its l'lai'igge or rim. but this is not essential. The glass front or lens 11 inserted in the lamp body and rests upon or oontarts with the front oi. the reflector, there being pref-- erably an interposed cushioning ring 20, of liher or similarmaterial. hetween'the flange of the reflector and the edge of the J glass or lens.

For the nn-pose of firmly holding the glass or lens in its place within the lamp body, I euniloy a split or divided ring 21 which is oonstriuited ol sheet metal having sullieient rigidity and elasticity to permit the o1urrations11nd perform the functions hereafter mentioned. This ring 21 is shaped with a eonsidmalde channel roll curve or groove and along its outer edge is flanged as shown at 3:2, this flange 22 being at a slight angle to the adjuoent ourred or rolled portion, and this flanged portion 22 is adapted to fit beneath the inner edge of the rolled portion 13 of the lamp liody, and when the flange 22 is so positioned between the rolled edge 13, the inner edge 23 of the ring wvill he held firmly against the outer faee'of the glass front or lens and hold the same rigid within the lamp body.

The ring 21' is slightly more than a ma plete circle so that when the ring; is posi tioned in the front of the lamp body, the ends thereof will overlap, as most clearly shown in Fig.4, and the overlapping end is;

slightly upset as shown at 24 in order to till end of the retaining ring has its flanged portion Q2 inserted. beneath the inwardly pro-- jecting edge of the rolled portion 18, end by proper manipulation. the entire flanged portion of the retaining ring is orced into engagement with the rolled portion 13 and the upset end of the retaining ring will. overlap the opposite end of said ring as most clearly shown, and by virtue of the fact that the ring has considerable transverse curvature or is rolled throughout its entire length, the inner edge of said ring will be held firmly against the glass and the overlapping ends freed, the entire ring can be quickly and easily disconnected.

I 'lheincendescent lamp 16 is connected to a. socket member which moves longitudinally in a sleeve 31 fastened to the lamp body at the central rear point and extending toward the reflector. Upon the outer endof I this socket member 30' is a knob 32 by means of which the socket carrying the lemp can be 'In'oved back and forth for the purpose of changing the'ifocus of the light, as it is well lnnownythat with the li ht. properly posi- 'tioned in a. parabolic re motor, the rays of light ere thrown directly forward. 'llliis produces a. glare, and In order to avoid-this concentrating glare, t is necessary to'slnft the position of the light, and this is ecco1n- ISO plished by moving the socket member 30=longitudinally in the sleeve 31, and for thepnrpose of maintaining the lamp in the desired adjustment, 1. pro-- vide a series of serrations are engaged by email spring 34 held within an opening in thesleeve 31 lay-means of a, clip or housing .35 secured to the sleeve 31, enveloping or extending over the coil spring 34 and holding the same properly positioned with reference to the s eeve; this-spring permits the socket meinberto be nshedin or out, but at the same time-has sn cient stren h to hold the socket member locked-att e desired point of adjustment. The sleeve 31 and socket member 30'are'cut away, to permit the introduction ofthezproper terminals.

Fr0m1the-forego1ng description taken in I connection with the i it will be seen that, I provide a simple. and

accompany ng drawing easily assembled means for securing the fore with the quick and easy arrangement of of'the lam body, the ends of said ring overthe socketmembenand, dep'iing, t

serrations 33in the" socket member 30, which retaining ring having an. outwztrdlybx tendret'aining ring hzfving an o'ut'vverdlv: g ing flange adapted to-engegc the rqlled'front r of the lamp body,'the ends of'saidring liver the ofi'set portion being devoid of sa-i flangp, e

- springrshe'etinetal curved trensversely" and having a revcrsely projecting flange extend l l' glass front or lens in the front of the lamp body and also that a simple and highly eflii cient means for changing the focus of the light is provided, and'ivvhich does not interthe reflector and parts dependent thereon.

Having thus dcsl'zribed my invention, whet Iclaimis:-. H
