My invention. relates to .reflector for .auto and other vehicle head lamps, unil 'the prima object thereof is to provide a. device of the shore-character by means of which the beam oflight from the -lurnp is-so reflected ns to eliminate all glare", while at the same time providing the lnfiiixiiniim road illumination,-

-thus providing. a. Safe driving 1i lit which while producing the greatest roa illumina; tion will not in any way interfere with the view lloin-the driver of an oncoming vehicle.

Another ob`ect isto provide a'- `reflector of the above c arxicter :which is interchange able with the reflector already in the light .and which can be easily and quickly positioned for u'se without'- in any way alterin the head lamp with Awhich it iS to be use Other `objects and advantages ywill appear hereinafter and, while I have shown an will discrihe the rferredorm of my invention,V 4

I wish it un erstood that, I Ado notliinit myself tosuch preferred form-but tlit `rai-louis: changes-and adaptations may be made theref i in without departing from the spirit of my ferrin' invention'.

In lthe 4drawings accompanying .and forminapnrthereo: "ig'. 1 is .a iront,l elevation of my reflector.

Fig. 2 is a side `elevation of Fig. 1.

F ig. 3 is n central horizontaljseetion of Fig: 1.. v 1

g. 4 Ais a section on the line .lr-4 of .Fi 1L i i consists o a-body '5- of n substantially parabolic configuration sirn'ilnr to .the pres'- ent type of reflector, provided centrally withV a eleeie 6 through which the usual lain Socket (not shown)l projects, and provides around its open end .with iin' anular rim If inwhich are cut notches 8 theV urpose of which will be obvious. The bo y portion of' my reflector, while hei-ng s uhstiint-iiill' ax-abolie in Shape, is' speciicall forme 'in a plurality of parallel, vertical y extending panels which are slightly curved in trarigirerse cross section, 'the center panel 9 end 10 of which ext-endV the full len th from the top to the bottomof body 5' we -oute-red'ges of the oixtei'mostpanels'lland 12 extend vertically fron-i the lower edge 0fhodyA to a.A short distance above the center to the. drawingmy rededor.

being so ifrsinged that the light will so reflected as topass out beyond the reflector onto the road-way for :t m-:ixim'urnrdfistance ahead of. thevehi'clennd at'the .proper height" to avoid inter-ference with. the riew'of an approaching driver inst-eed of being ditfiised into the atmosphere in all directions as with the present type of reflector".

Having described my invention, what I claim is:

fio'

1. In a lit-mp .a ribbed reflector, the ribs Y thereof beingcur'ved outwardly in transverse cross section and cls .tei-idi-ng perpendiculiirly -to a horizontal plane pnssingfthr'oughthe re- {lect-or the clior s ofsaid curves being at an oblique en le to: the :ax-is of said reflector,l

the two a jacent: center ribs-extending the reflector and theremain-mg ribs having their entire distance from top to vliottomof said upper ends tapering 'downwardly 'away from mid-center. ribs, the. outermost ribs' ybein-g wider than the other 'ribs and `spaced from the side wall of said redentor;

2. A reflector for vehicle headlanips .comprising va .l substantially parabolic shaped 'cesinform'ed in its medial portion into a pliiraity of iircuii'te relatively shui-low ndiciil'ar to panels extendin; inplzines a said a horizontal p ne 'passingti'rouh casing, the 'center panels extending zi-4 entire Wall of. said Casin bottoni, the panels iiteach' si e of said center panels tapering at their upper ends-down,-

n'ardly away from sii-id center p z'i'nels, the" (interi-nest panels lic-ing wider than the other' pzinelsend being spacededistance from the ong thefrom top to side wall of saidczising and the chordi'of l ciifrvatiire'of sai-d panelc'lie'ing tziigential to the curvetureoisaid casing.
