LAMP.
Application filed October 24, 1918. Serial No. 259,461.
To all whom it may concern:
Be it known that JOHN W. BROWN a citizen of the United States, residing at otion uponthe lamp body.
lumbus, inthe county of Franklin and State of Ohio, has invented certain new and useful Improvements in Lamps, of which thetollowing is a specification.
This invention relates to lamps and is designed particularly for use in connection with automobile lamps where it is frequently necessary to remove the cover or lens ring. The structure is designed w th a two-fold purpose in view, these being to guard against the accidental dislodgment of the lens ring and secondly, to always maintain the reflector in its proper focal relation with the lamp body no matter how many times it is necessary to remove the lens ring. These objects I attain by the employment of a shelf structure upon the lamp body which cooperates with a complemental shelf structure on the reflector together with means for drawing the lens ring into its applied posi- This latter operation is usually accompanied by a partial rotation of the lens ring upon the lamp body and to positively guard against accidental removal of the ring, and supplemental latch structure is provided whereby, when the lens ring and lamp body have reached their proper relative positions of association, the
latch becomes effective to permanently hold the parts in their assembled relation.
The preferred embodiment of my invention is shown in the accompanying sheet of drawings in which similar characters of reference designate corresponding parts and in which,
Figure 1 is a view partially in side elevation and partially in central section illustrating my improved structure in connection with an automobile head light,
Fig. 2 is a fragmentary perspective look ing from the inside of the lens ring, and
Fig. 3 is a fragmentary perspective of a portion of the lamp body showing one of the shelves upon which the reflector flange rests and the spring means for drawing the lens ring into proper position with the remaining lamp parts.
In these drawings, thelamp body is designated by the reference numeral 1 and is illustrateeiwith particular clearness in Fig. 3, a plurality of angular shelf elements 2 are applied at proper intervals. This latter structure comprises an upper fiat main shelf 3 and a depending tongue'portlon 1 which forms a means tor properly attaching the shelf itself to the lamp body as'shown for,
instance at 5. This means of attachment may take any desired form. It will also be noted by reference to Fig. '3 that the shelf proper 3 is located slightly beneath the upper edge Got the lamp body and. it is upon these shelves that the cooperating flange or shelf 7 carried by the retiector 8 are designed to rest. By the provision of this structure, the reflector can not vary from its properly applied position with respect to the lamp bulb although the body itself may be adjusted to alter its focal. arrangement by means of the structure illustrated diagrammatically at 9. The lamp body and reflector are closed by meansot the lens 10 suitably mounted within the lens ring 11. This lens ring is provided with a plurality of slots 12 located in the flat portion or complemental shelf portion '13 which is designed to rest upon the flange '7 of the reflector as shown in Fig. 1. The surfaces defining and immediately surrounding these-slots are perfectly fiat as is illustrated and it is through these slots that the spring hooks 142 are designed to pass. It will be noted by reference to Figs. 1 and 3 that these spring hooks are each formed of a single piece of \wire provided with reverse bends 15 and 16, the latter projecting through the shelf 3 as shown at 17 and carrying an engaging portion 18 at its extreme end. Each of these wire hooks is secured at its opposite end to the shelf 3 by any suitable means as, for instance. the bolt and nut structures shown at 18. The reflector flange suitably out out to accommodate or to permit the passage therethrongh of wire hooks 14 and these hooks then engage the lens ring by passage through the slots 12 and a partial rotation of the lens ring in its applied position upon the lamp. The hooks 1-1 are preferably made of spring wire in order to at all times exert a tension upon. the lens ring urging it into firm holding relation with the remaining lamp parts to avoid. rattle.
In order to prevent the accidental dislodgment of the lens ring after it has been properly applied, I have provided an auxiliary latch which takes the part of a spring wire 19 suitably secured at one end as shown at 20 to the lamp body and having a substantially right angular bend 21 at its opposite end. The lamp body is provided at this .point with an aperture or slot 22 and the Ilene ring is itself provided with a slot 23,
these slots being designed to aline when the parts are in their properly associated position to permit the end 21 of the auxiliary latch to assume the position shown in Fig. 1Q It will thus be apparent that the parts are firmly locked against accidental ,be desired to remove the lens ring, all. that is,
necessary is to force the auxiliary latch inwardly by pressure on the button 2-2: and then partially rotating the lens ring. Similarly, this auxiliary latch must be slightly retracted when the lens ring is applied.
v il hat I claim is:
l. in a headlight, {113.1111} body, a reflector therein, a laterally projecting shell struc ture carried by said reflector, a plurality of coiiperatiiig shelves of angular form secured to said body and formed of an upper fiat portion arranged circuinlie entially within said body and beneath its top edge said fiat portion terminating in a'depending tongue, a spring wire secured at one end to'the underside oi the fiat portion of each shelf and wires projecting through their shelves for flange formed circumferentially upon said I reflector and arranged for seating cooperation with said element flanges, a lens carrying ring removably fitted upon the open end of said lamp body, said ring including a slotted reflector engaging shelf portion, and a plurality of resilient'hook members of spring wire formation secured to the inner sides of said shelf elements, each member including a pair of reverse bends, the intermediate portions of which being arranged to project through registering openings formed in the flanges of said shelf elements, the slots of said reflector flange and the slots of the. shelf portion of said lens ring,'whereby.the bends formed upon the free ends of said hook members will be brought into engagement with the shelf portion of saidlens ring to drhw the latter inwardly into clamped relationship with said reflector and bod provided with a pair of reverse bends, said In testimony whereof IaiiiX my signature.
JOHN W. BROWN.
