AUTOMOBILELAMP.

Application filed January 10, 1921. Iseria1 no; 436;10s.

To all whomit may cancer n1 'Be it known that LiOLA E. ALLEN, a citizen of-the United Statearesidinglat Cleveland, in the county of Cuyahoga and State of Ohio, have invented acertain new and useful Improvement inri Automobile Lamps, of which the following isa full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates generally to lamps, and more particularlyto; one iintendedfor use upon motor vehicles; and'the object of the invention is to provide 1 certain novel means for securing the reflector andglass in thelamp body so as to avoid'rattling.

Anotherobjeot of the invention iss'to provide means for connecting these'parts, independently, vthat is, means for connecting the reflector to the lamp ibody,*zseparate means for connecting the glass to the reflector; and-still further independentmeans for securing all within the lamp-body: I p v A still further object is to provide certain improvements in these parts whereby they may be quickly and easily arranged wvithin, or removed from, the. lamp body; and a still further object is to provide anovel construction of ring fasteningameans so that access to the lamp for the purpose ofc'leaning the same, or replenishingthein'candescent bulbs can be quicklyiandeasily accom- Plished. 1

- With these various objects in view, theinvention consists in certain novel' features of construction and also in the manner of combining or arranging s'aidflparts', all of which will be fully described hereinafter and pointed'out in the claims. 1' 1T In the drawings forming a partofzthis specification Fig. 1 is a face view partly inv section of a lamp embodying my invention;

2-2 of Fig. 1; Fig. 3 is a detail view showing a portion of the lamp body; Fig. 4 is a similar view of a portion of the reflector;

Fig. 5 is a section on theline 55 of Fig. 1. j-

thereby efi'ecting' the connection of the reflector through the' lampqbody. 'Thegbow" I e axially extending circumferential :flange '11.

This sheet metal'body portionmay. be provided with any suitable form of attaching bracket; and is also provided with socket connections for the main and the auxiliary or d mmer" ncandescentlights; I

The clrcumferential flange is provided with radial inwardly projecting lugs 12 preferably at equidistant v points, said lugs' being formed by punching the: metal in- 'wardly, and :the circumferential flange is also formed, preferably atequidistant points Inetalinwardly, and'in addition to theseries ing in the fOIIIl Of an inwardly extending receiving :the; auxiliary or dimmer light. 2

"with inwardly extendin ears 13 which are I also preferably-formecfby punching 'the bow having the ends 15 thereof turnedfto enter the inwardly projecting ears-13. f 1 :The reflector l6fis preferably ofparabolic type and has a central opening, to ,7 receive the socket of the main light; and is also4pr'ovided at the proper placewith arsocketfor At: the outer edge of theparabo1oid,-t'he reflector is formed with a circumferential, beadl? which is substantiallyrectangular in cross section :andprojecting outwardly from this head is, the radiallyv extending ,cir-

cumferential flange 18 and the flangawith reflector isofv such size asto fit snugly within the circumferential axial edge or :flange portion'll :of; the lampv body, and the circumferential flange 1810f the reflector contacts with and bears upon the springs 15 carried by the lamp body 10. i

T Atxdefiniteupoints, the reflector, flange'eis provided with notches 19 throughgwhich the l I inwardly projecting lugs 12 of-the lamp body are adapted, to pass,.and'thenby giv- I in'g thereflector a slight circumferential fmovement, the flange thereof can. be moved beneath the inwardly. projecting lugs 12 springs 15 carried byythe body being subjected to tension andacting as they deconstantly upon the flange of the reflector hold 5 the reflector and body in locked relation andprevent rattling. In practice I prefer to upset the flange 18 at one point 20 adjacent one of the notches 19 in order to limit the circumferential movement of the reflector flange beneath the radially inwardly pro- .ojectinglugs.

' Thereflector flange is provided with a plurality, (preferably three) hooks or retaining members 21 each one comprising a portion which extends axially outwardly, and a portion which extends radially inwardly, and the lass can be inserted from one side and brought into engagement with said hooks or retaining members, and the periphery or edge of the glass will contactwith v the axially extending portions, while the radially extending "portions overlap the edges of said glass and prevent any movement-thereof. In practice,-I prefer to arrange a cushion ring'22'of anysuitable materiallupon the outer face of the head of the reflector and against which'the inner face of the glass will contact.

Inorderlto hold the glass inrplace upon the reflector, and also to eflectively close the -.outer or front edge of the lamp body, I pro- 1 vide a sheet metal ring 23 whichis flanged or channel shaped-in cross section, the inwardly projecting edge thereof being adapted to contact with the outer face of theglass,

'and the outwardly projecting edgethereof being adapted to pass around and envelop 1 the outer or forward edge of the body; and

in placing thisring upon the body it is first inserted over the outwardly projecting lugs 24 and then brought over the opposite side of the "lamp body, and in order to secure the locking ring in engagement with the lamp body,

and the outwardly projecting lugs-in par- ]ticular, -I employ a latch25 within thelamp body and having its outer curved or hooked end 25 working through an opening 26 prolatch contacts with a bow spring 28 held in place bythe additional pair of'inwardlyprojec'ting ears 1% and, as the screw is tightened to project the outer curved or hooked'end of the latch outwardly, the central portion of the spring is-p'ressed inwardly and exerts a constant pressureupon the latch, so that when the screw is loosened, the outer end of "the said latch will beimmediately forced inwardly inside the'lamp body so that the ad jacent portion of the ring 23 can be lifted "clear of the edge bf the'lampbody, and after that side of the ring has been cleared, a

slight movement of the ring will carry the opposite side away from, and out of engagement with, the outwardly projecting lugs 24,. andthe ring will be then entirely clear of the lamp body. v

The glass, however will remain in its proper position upon the front of the reflector, being held thereby the hooks or'reta'ining membersQL' a By removing the ring and glass, access can be had to the lamp for the purpose of cleaning thereflector or; replenishing the lights, and in case it is desired to remove the reflector itself, it is only-necessary to first remove the main incandescent llght, and then give the reflectora slight'rotary movement, so as to bring the notched edges thereof;19-op tween the body and reflector and therebyeliminate rattle at this point, and the ring securely holds the glass, in place'upon the Y cushion ring of thereflector and consequently all rattle at: these points is eliminated.

carried by the lamp posite the inwardly projecting lugsxl2;-and

The various features of constructionherein set forth lend themselves readily to reduce the cost of production in providing a highly eflicient and easily manipulated headlight lamp for motor vehicles.v

Instead of employing be provided, or any other suitable bolt or latch actuating device mayt be employed;

an ordinary screw,' to operate the latch, I may provide said screw w1tha milled head; orv a wing nut may and it will also be understood that: certain changes or modifications imay bev made with reference tothe other details of construction within the scope of .the' ap ended claims; I

Having thus describe my r invention,

' lamp body for limiting the inwardmovean axial circumment of the reflector, and'springsuattached to the axial edge of the lamp body and adapted to engage the flange of the reflector, a glass held in contact with said reflector, a

ring, engaging the outer face of the glass and I the exterior of the lamp body, and a latch I arranged uponthe interior of the lamp body .at one side, and a screw working through the lamp body and adapted to'actuate said latch to-holdthe ringiinplace.

' 2. In a lamp, thecombination with a body I having outwardly extending portions ad jac'ent the forward edge at onesidethereof, said body also. having inwardly projecting lugs, of springs carried by said body, and

a latch also carried by said body having its r outer end workiirgthroughi an opening in said body adjacent the forward edge thereof, a reflector arranged within the body, and resting upon the springs carried by, said body, the outer edge of said reflectorengag ing the inwardly projecting lugs, a glass arranged upon the frontof said reflector, means carried by said reflector to hold said glass in position and a ring adapted to envelop the outeredge of the lamp body and the outwardly pro ecting portions together with means for actuating said latch to en-y gage said o ring.
