doorle'ss headlamp of simple -construction so that the lens may be readily removed. whenever desired but nevertheless one so well constructed that the parts are at alltimes held tightly-together'and well sealed, preventing the entrance of fdust or water. r

The invention is characterizedby the'iact that the lens is secured-y di'rectly to the lamp'housing, beingprovide'd at one edge withfa projectionor notch interlocking with" the housing and at the opposite edge .with suitable fastening means which serves to draw the lens into'engag'ement withthe' open end 'ofthe housingf To maintain the parts in engagement, springpr'esjsure is so applied as to urge the lens outwardly 'and thisspring pressure is likewise preferably utilized to yieldingly urge a sealing gasket ag'ainst,the-lens. j y

I In the'form shownin Figures 1 to 4 the head lamplhousing. it] is provided on its upper portion with inturned flange l2 preferably crescent shaped when viewed from the front. ,Within the housing ispflx'ed an angledring. wi l adapted to support the flange it of the usual reflector i8. The reflector is preferably located with respect to the housing by means of pin Zii secured to the edge of thereflector' and passing through a slot in'the vertical flange oi the ring i4. Bowed leaf springs such as tained; 4- v In; the formshown in Figures 6 and 7, the lensis Qprovided with-an arcuate projectioniw, which, a combination with the adjacent portion of the shownv at .21. are provided between, the flange .of therefiector andthe ring M, the springs having theirfr'ee endsinzengagement with the flange and theirintermediate portions engaging the back of thereflector flange; Three springs are provided,

I equally spaced about the circumference.v of the. flang'em .The springs urge the'reflector toward the opening in the housing. The edge of the reflector 18 is preferably'channelled as shown to receive the sealing gasket. 22. .The lens Mismounted in the headlamp by inserting its upper edge portion,

the reflector rearwardly against the resistance of springsvzlhv The bottom ofthe lens isprovided with a socket 28 adapted to receivea clip 38,, shown in detail in Figure 3. The clip is clampedto the housing by means ofstamping tzjclamped'to (bracket 34 secured to the housing, by. screw bolt 3.6. If desired the clip-3d; and stamping32 may be'made in one pieceas shown atSB'in Figure 4. Lug 39 holds the'clip to the lens.

'With this construction theusual lens ring is "omitted, its function being performed by the flange on thelhousing. and the clip til-32 ores. At the same time the. 1 appearance of the lamp is improved; and all of this is accomplished with a considerable reduction in cost.

pressedoutof the metal .of the. ring Mt: With this construction the flange I2 is, unnecessary so thatthe appearance of the lamp is furtherenhanc'ed since the usual circular .lens opening is re lens, forms a slot 9| in which is received the inturned flange of the lamp housing. In this modi- "WhichJmay' take the formbf a flangefifi, behind I the, flange 12, this being accomplished by pressing fication there isfixedly secured within the headlamp a split'ringiill L-shap'ed injcross section;

Therefiec'tor 94 is'pro'vided with the usual gasket "receiving groove 96. The reflector is secured to the split ring 92 by fastening means'in the form of, pins 95 projecting through apertures in the base of the groove 96 and through alinedapertures.

aresecured-enlargements 93"00 prevent their Withdrawal. Springs I09 encircle the pins W5 and of the ring 92. a

in the split ring 92; To the ends or the pins As shown in Figure '7 I prefer to provide three or" the pin assemblies, one at the top and one at each'side of the lamp, while the lamp is held at the bottom by means of a clip I04 engaging socket I05 in the lens as in the precedingv figures. The securing means for clip I04 consists of screw bolt I06 passing 'through an aperture in the clip and threaded at It! in stamping I08 secured to the lamp housing as by riveting over an outturned annular flange I 10 formed'out of the metal of the stamping. Coil spring II2 engages collar II 4.0n the bolt I06 and yieldingly" resists outward movement of the bolt. It will be apparent that by rotating bolt I06 in a direc tion to compress spring H2, clip I04 is released; so that itmay be disengaged from socket I05} lock between lens and housing. It is clear of course thatthe lens holding devices need not be at the top and bottom of the lamp but may be at opposite sides. .More than one lens retaining 'clampmay be used if desired.

' Obviously in place of the rings shown at I4 in Figure 2 and at 92 in Figure. 6; a plurality of circumferentially spaced clips may be employed, these clips being suitably welded or soldered to the body- This really amountszto no more than making the rings discontinuous. 1
