HEADLIGHT.

Specification of Letters Patent.

Patented Mar. i0, 1918.

Application filed July 13, 1916. Serial No. 109,015.

.cially adapted for. automobiles and other vehicles, and'has for its object to provide a simple and eiiicient means for keeping in vproper adjustment, light bulbs which either have two lam'ents whichshould beset verticallyl or which have a'single diametrically extended filament that should be .set verti-.` cally, or for that "matter, in any cer'tainposition, in respect to a vertical, necessary in order to get the best or desired results.

The feature of the resent invention'consists in combining a light bulb of the above character with a reflector that is capable 'of rotary or oscillatory adjustments with the light bulb', to set its filament either vertically or in predetermined positions, in respect to a vertical. v

In the accompanying drawings which illustratethe invention, like characters indicate-like parts throughout the several views.

Referring tothe drawings:

Figure 1 is a front elevation showing the improved reiector; and

Fig. 2 is av vertical section takenon the line w2-2 of Fig. 1, the clamping rim of the headlight-'being removed.

The case 3 of the headlight has a 'rigidly .secured angular facing rim 4. The clamping rim 5 which holds the lens or glass plate 6, may be of the usual or any suitable construction detachably secured to the rim of the casing, by the customary joints or other suitable devices. The reiiector 7, which, as stated, is mounted for rotary adjustments within the casing, is formed with a rim portion 8 held between the rims 4 and 5.

Springs 9, .as shown,.threein number, are interposed between therims 4 and 8 and yieldingly press the latter forward. These sprin as shown, are I nade from piecesof bowe spring wire having their ends 1nserted through perforations in the rim 4.

The rim 8 is provided with segmental slots 10, as shown, three in number, and adjacent to the edges of these slots, said rim is formed with serrated surfaces 11. These serrated surfaces 1 1 are engaged by the V-shaped edges of the angular heads 12 of studs 13 that are riveted, soldered, or otherwise rigidly secured to the rim 4 and 'are extended throughthe cooperating slots 10. At one extremity, the slots 10'are provided with ltransversely enlarged passages 10a through which the heads12 may be freely passed,

when alinedtherewith by extreme rotationl of the reflector in one direction.

Under the tension of the. springs 9, the ser.

rated surfaces 11v willbe held engaged with the angular heads 12 with suiiicient 'force to prevent accidental rotation ofthe reflector, but nevertheless, the said 'reflector may be easily rotated 'when it is' pressed lslightly rearward and then given a turning force'by the use ofv a persons hands.

The electric light bulb 14, as shown, is ofA thetwo-ilament type, being provided with an axial filament a and an offset filament b, and t-is provided on its shank with the customary metallic contact sleeve' 15' having idiametrically projected lock lugs 16 -Thesleeve'l is insertible into and closely lits a sleeve-like socket 17 that is secured in the lrearwardly projected sleeve-like axial hub 18 of thereector 7. The lock lugs 16 are adapted to be engaged with bayonet slots 19 formed inthe socket 17 and to be held l interlocked therewith by the tension of a coiled spring 20v compressed between the shank of the bulb and an insulating plug 21 secured inthe rear end ofthe socket 17 and serves to support certain of the electrical connectionsto the light bulb. These .electrieal connections need not here be considere It is evident that when the bulbis applied to the socket, and hence, is secured in respect 4to the reflector, its filament orlaments may not always stand in a vertical plane, but that they may be accurately set in a vertical plane by rotary adjustments of the reiiector within lthe casin What claim is:

1. In a headli ht, the combination with a reiector mounted for rotary adjustments, of an electric light bulb mounted therein and partaking of a common rotary adjustment therewith, and means for holding said re- Hector against accidental rotation, comprising a serrated surface onone of said parts, and a coperating head onthe other of said vparts,4 the said head and serrations being spring-held in contact.

2. n a headlight, the combination With a casing, of a reliector rotatably mounted 5 therein and provided with a marginal rim having segmental slots and serrations adjacentto said slots, studs applied to said casing and Working through said slots and provided with heads engaging said Serrations,

10 and springs interposed between said casing and the rim of said reector for yieldingly holding said serrations and coperatlng heads in contact.

In testimony whereof I affix my signature in presence of two witnesses.
