HEADLIGHT CONSTRUCTION.

Application filed December 5, v1921.

To all whom it may concern:

Be it known that I. rimmer Myrrnonr, a

citizen of the United States, and a resident of Connersville, county of Fayette, and State of Indiana, have invented a certain new and useful Headlight Construction; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

This invention relates to a lamp construc tion, and more particularly to the means for clamping the lamp door and reflector to the casing, whereby they will be maintained in position under spring tension and be readily removable therefrom.

The particular feature of the invention lies in a single spring construction for yield: ingly securing the lamp door and reflector in position, and causing the lens to be clamped against the reflector or casing under spring tension in such a manner, that by a rotary movement, the spring will become disengaged and the lamp door and reflector may be removed.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims.

In the drawings, Fig. 1 is a front elevation of a lamp with a portion thereof cut away to show one of the clamping springs mountedon the inside thereof. Fig. 2 is a section of the lamp showing a rear elevation with the back portion of the lamp removed for disclosing the clamping means. Fig. 3 is a section taken on the line 33 of Fig. 2. Fig. 4 is a side elevation of a portion of the lamp with the door rim removed.

In the drawings there is shown a lamp construction having a casing 10, reflector 11, door or lens rim 12 and lens 13. The casing has an inwardly and radially ex tending flange 14 about its outer edge, and the reflector 11 is provided with a radially and outwardly extending flange 15, said flanges being arranged so as to be clamped together as hereinafter set forth. Between the flange 15 and the reflecting surface of said reflector, there is an outwardly projecting portion having a groove extending about the surface thereof to provide a seat for the cord 17 against which the lens 13 is pressed for sealing the reflector and pre- Serial No. 519,952.

venting dust and moisture from entering therein.

Secured on the inner surface of the flange 14, there is a spring clamping member 18 comprising a strip of spring metal having an end 16 reduced at 19 adapted to pass through a suitable opening in the flange 14 and extend therethrough to yieldingly engage and clamp the flange 15 of the reflector by the extended lip or end 16. The other end of said spring is secured by extending it through a suitable slot in said flange which forms a permanent seat therefor. The ends of said spring are, therefore, secured to said flange in such a manner as to cause the intermediate portion thereof to bow outwardly from said flange, as shown in Fig. 8. Said spring is formed with a saddle 21 comprising a comparatively small recessed portion included between adjacent shoulders for forming a locking seat.

Rigidly secured upon the door or lens'rim 12, there is a'projecting member 22 having one end 23 thereof bent so as to loosely hold the lens 13 in position while the door is being mounted or dismounted, and the other end 24 being arranged to extend radially and inwardly from said rim so as to engage the spring 18 and slip into the saddle 21 for removably locking said door rim in 'posi tion on said casing. In mounting the door rim and reflector upon the casing, the reflector is placed in position so that thefianges 14 and 1-3 lie adjacent each other, the reflector is then turned so as to cause the pro- ]ecting lip 16 to extend through an opening therein and yieldingly engage said flange, thereby clamping it in fixed position under spring tension. The lens 13.is placed in said rim so as to be maintained therein by the ends 23 of the member 22. The rim is then mounted about the outer edge of the casing and rotated thereabout until the in wardly extending end 2d of the member 22 passes through a slot 25 in the periphery of the casing, engaging the upper surface of the spring 18, away from the door rim, and sliding thereover, causing it to be pressed downwardly against the spring tension thereof until said end falls into the saddle 21 between the adjacent shoulders. Further movement of said member 22 is then arrested by the end of the slot 26 being reached and its abutment against one of said 0g :1 spring ternictliute portion of Within said casesure extending in 1d closi relativel v tn sting of 21 ie flange of spring ex- (l extenilin e0 am the Width of the i'crsely to the {DES of the earsrounding the (1 within the g; flange adjacent i-r en Slid spring memng said rlcsure to i infurneil sub- 65 e sur ineuni: an outturnml annular e inturned flange 0% the ng, and means 70 g, retle-tur 2n ction coi'nprising; an inning 11 fl i positi ans cons extenii her said cusi iugg its oil he in g houexl inwardly from snul said ill engage an eel;
