To all 'whom it may concern:

Bc it known that I, lluuusu'r lt. PALMER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Lamps, of which the following is a specification.

This invention relates to improvements in ,lamps of the character commonly known as head-lights that, are used on nlotm'-cycles, automobiles, motor-bruits and other vehicles, and wherein electricity is employed as the medium for lighting the way In advance of the vehicle. While the lights of this character are adopted. more or less 'for the convenience of the occupants and drivers ot' the vehicles, there are numerous regulations or ordinances that must be complied with. These ordinances hate particular reference to the lights used on automobilesI and motorcycles thatJ are operated on streets or public high-ways, and the principal object of the present invention is to provide a lamp for thisV purpose that will meet all the requirements. A further object is the provision of an economical construction embodying means for meeting said requirements and enhanein the efficiency of the lamp.

y improvement. provides For the obviating ofthe dazzling brightness or flare wilhout diminishing| the illuminating power of the lamp. It, further provides simple and convenient means for focusing or adjusting the light member relative to other (zo-acting elements of the lamp. lt also provides l'or universal iuljustinent ot the lamp as a wholel relative to its support and to the high-way. The improvement still further provides a secondary light, member Qt comparative Small dimensions and correspondingly low lighting capacity, which is operated indcpendently of the main ilhnninating member for usewhcn the vehicle is at rest t'or tbc urpose of identification or to denote the ocation ofthe vehicle when the main lights are extinguished. l am aware that. small Secondary light. members have been used in connection with lamps for this purpose, but as heretofore constructed and arranged the secondary light member has been so located as t0 obstruct the rays and greatly diminish the illuminating etlieiency of the main light member when said member was active, while my improved construction provides for a secondary l/ight that does not interfere with the illuminating power of the lamp.

With the above and other apparent objects in view the invention consists in the general construction, arrangement and comination of the parts as hereinafter described and pointed out definitely in the claires, reference being had to the accompanying drawings in which similar characters of reference designate similar parts.

In' the drawings Figure 1 is a front view of the improved lamp with a portion of the rim broken and the mounting trunnions not Shown.

Fig. 2 is a central vertical 1 1, Fig. 1.

Fig. 3 is a plan view of the improved lam Fig. 4 is a section on line 4-4, Fig. 3.

Fig. 5 is a horizontal central section of the anti-glare elements assembled and detached from tbe lamp casing, and Fig. 6 is a perspective,view ot one of tbe blades used in the construction as hereinafter described.

ln `order to obtain the best results or the greatest'. efficiency through the co-aeting of thefdifl'erent elel-nents that enter into the general construction of' the improved lamp, an adjustable mounting means is provided; to this end truhuions 1 are riveted, brazed, or welded to the lamp casing 2 on thc same horizontal axis. These trunnions penetrate mounting blocks Il, being adjustable therein and when adjusted as desired they are, made fast by set screws "I. The blocks Il are provided with vertical openings adapted to accommodate the stems 5 of the stationary fork 5 being vertically adjustable therein and made. fast by set. screws t. liy this arrangeuu-.nt the lamp casing is made applicable to forks varying in'the dimensions between stems 5", and is also vertically,` horizoutally and augularly adjustable relative to its stationary support; This universal :nljustability ot the casing in combination with other features is a prominent factor' of ellieiency.

The ililuninatplg member 7 is mounted in a suitable socket Hthat has a stifling bearing in thcJ-ltlector member 9 as shown at 9 Fig. 2, and longitudinal adjustment of said socket and illuminating member is provided t'or by the screw 1() swivelcd in the socket H and threaded inplate 11, which plate is adjustably attached to the casing 2.

The reflector member for projecting the light rays is made in a series of connected annular parts of different characteristics as section on line follows :-The portion .9 is parabolic, the portion 9 is also parabolic, while, the interposed part 9 is circular. The functions of this composite reflector will presently he explainc Attached to the front of the casingr i), is an extension harrel member 12- Said memhor 12 provides retaining means for the transparent laee 13 and also has confined therein a grille member which is constructed ftillo\\'a:-An annular shell 14 provided with a flange 14 has segmental longitndinally extending partitions l5 and 1G arranged therein e'aibatantially1 as shown in Fig. 1. These partitions are formed in aeg-v mentn havingr the same radial dimension as the annular shell 14, they are prrn'ided with flanges 15 and 1G and form a central openingV adapted to accommodate or form a frame for a prismatic glass nn'mher 17 of elliptical or eats-eye Shape as shown. 'l`he compartments 18 and lll which anrronnd the elliptical trame memlier are provided with longitndinal partitions or bladey 2t) arranged parallel in horizontal planea. spared apart and supported on each other hv tlm nieinhers; 24) which are preleialil)Y integral with the blades 2t) heilig ent and turned dmrnward lrom the hotly of the blade` as besty shown in Fig. (S. The blades Lft) hear on the Hangin,r 1l` l5 and lll" and heilig snpported on each other 'form a dnrahlr and easily assembled Strnctnre willich is held in the barrel memher 12 hy Snil'ahle meanS. as for example binding spring dorirea 21. lt will he noted that this novel construction provides for the members 'l0 being counter parts. that is;` with the exception ol a vlew that are located near the terminala` of the segments, they are all of the same dimension. they are therefortn with thin exception, interchaagreable. thas greatly facilitating v the asnnnhling of the device.

(lentrally located in front ot' the illnmi Hating member 7. and for Convenience of assemliling. attached to the members l5 and lli. is a yhell 22: aid Shell is circular in cross-Section and has a paralioli(- fare 22, The shell 2:2 is so arranged that the` outer pcripliery 22" iS: in a longitudinal pla nr with the annnla r connection of the retlertor memA hers 9b and fl, and the inner periphery 22 is in the same plano as the connection of re- Hector men'ibers. 9 and 9.

lt will he seen that light rays emanatimglt from the illnlnitntting;r mrmher T will he pro jorted a longitudinal direction it. ai. n. from the reflector il". Rays will he projet-ted in the direction l; from reflector Sl. and raya from the parabolic member 2Q vwill he projected as shown by c. t" while the retlrrtor 9 projects the raya diametrirally through the illuminatingl member to the oppositier parabolic portion 9"; these rays then takt' the direction a, a. This novel arrangement eloae proximity to the front ol` the vehicle.

l am aware that tlnA lnoatl principle of applying a grillo structure to the lront of a head-light for thtl purpose ol' controllinlgr the glare is not new in thc art. hut as far as I ltnow the, economical construction and ar rangement ol' the elementsA that malte np the4 grille strot-ture and the particular combination ol' =aitl fi-ille `tt-netart: with the other lamp elmnentsw eonatrmtetl and arranged als tlefatrilitil is novel.

erontlary light member Ll ot' Small diannter. or anllatantiallv the vanni diameter as the wel-:et H n located in front and in the longitmlinal axial plane of the illnminat in;r memhrr T and the reitet 8. sockel; l ia ronnettrtl with the lgrillo structure h v snitalile mean.` and is adapted to receive theslem ot' the light member 23 providing snitahle elet-Iritconnections therefor. The :toeliet a in a oml pole socket and is connected hy the eondnrtor 25 with a two pole Socket 2G which n .-ntaelad to the casing 2 and provide eonnert ing moana for the two pole plug ijt'. 'lhe meldt 'l is also a one pole socket and is ranno-ted with the socket 2G by the eomlnrtta' 2H, Socket- S and 2l have gronndsl connection thronfgh the casita,r and two roinloetora Lh and 2S eonnett the rolldoctora :.Ii and 2n through the plug 2i' with a snitalile mvitrh not `ahown.

lt will he understood that there may be modilirat'ina4 in the details of construction without atl'eeting' the cooperative arrange ment of the several elements whereby' the desired results: are obtained` and while I have uhown and deacrilrd a lamp embodying a consti-action that provides for the proper combination and arrangement. I am not conlined to thi` speeitic construction only so far as, limited by the scope of the claims.
