To all whom t may concern: y

Be it known that l, CLAYTON O. 'Wnirn, a citizen of the United States, and resident of the city of Seattle, county of King, and State of Washington, .have invented certain new and useful Improvements in Headlights, of which the following is a specication.

rllhis invention relates to new and useful improvements inheadlights, and more. par- 3-0 ticularly to headlightsof that character especially useful on motor vehicles the principal object of the invention being to provide a combination which embodies features of the usual automobile spot light and antiglare headlight ,whereby a central shaft of light of effective intensity may be projected directly forward of the light, and whereby other rays may be projected in a less intensified beam that will substantially light 23 up a roadway forwardly of a vehicle eguipped with the light but will produce no g aring eiect outside of the spot light beam, and other rays will be reflected laterally to both sides of the roadway.

35 ln accomplishing this and other objects of the invention, l have provided' the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings, wherein-- Figure l is a central sectional view of a headlight constructed according to the present invention.

F igure 2 is a front view of the saine.

Fi ure 3 is a transverse, sectional view on the line 3--3 of Figure l.

Referring more in detail to' the several viewsv of thedrawings, wherein like reference numerals designate like parts--the numeral l designates a reflector body, which 40 may be made in any desirable or suitable size and of any desirable'material suitable to its particular use, and which consists of a short cylindrical portion 2 which, at its forward edge is turned to form a peripheral l5 flange 3 and continues at its opposite end into a truncated, conical portion 4 which terminates in a .sphericall curved end section 5; the center aboutw ich the spherical reflecting surface is formed being in "the axial line of the conical and cylindrical refleeting surface.

Forwardly of the reflecting surface 5 is an electric lamp 6 which ma be mounted and adjutsed in any of the we l known ways now employed, and electrically connected with circuit wires for supplying electricity thereto.

The intermediate, or conical portion 4 of the reflector body has ribs or ridges, 7, formed therein which extend in the general axial direction of the cone at regular distances apart with the body portion-con caved transversely between the ribs,` as isv particularly illustrated in Figure 3, forniing depressions 8 intermedial the ribs which entend the'length of the conical portion.

A housing 9 is formed to 4receive the rewith an inturned flange at its open end against which the flange 3 may seat. Also a ring member l0 is applied to these parts to hold them functionally together and also secure a glass plate or lens l1 at the front of the housing as is ordinarily d one.

ln using a headlight of this character, the lamp 6 is located in, or adjusted to such position, that the best results will be gained from the spot light reiecting surface; that is, so that it will cast a narrow and intense shaft of light directly forward of the re Hector.

It is apparent also that the shaft of light produced or thrown out by the spherical or 'spot lightreflecting surfaceq will be surrounded by a much less intense light reflected from the ribbed conical reecting surface 4, which, being so ribbed, will effectively diffuse all light rays reflected therefrom that no undesirable glaring eifect is produced and a roadway forward of a Vehicle,

flector body, and this preferablyis provided equipped with such a light will be plainly visible.

It is also noted that the cylindrical reflecting surfaces 2 will cause other rays of light to be cast laterally of the direction of light from the other surfaces and will serve to illuminate objects adjacent opposite sides of the roadway. i

It is to be understood that the extent of the spherical and cylindrical reiecting surfaces and conical surface Ilv are subject to modification and I .do not Wish to be limited Having thus: described my invention, what l claim as new and desire to protect by -Letters Patent, is: y

ln a headlight, .in combination, a reilector body comprising a truncated conical redecto the'exact form asillustrated.

tor surface 1n terminating at. the smaer end a Spherlcally eurvedrefecmg suface formed abou; a cener whxch hes 1n the axial -'ine of the eoniea porion, and at s end extended into a cylindrical.

reflecting surface; said eonea bodyI prion having ges extending ongltudnaly thereof nd conceived nntwardlv between said ridges, Wardly of the spherical relecting surface:

and in the axial line of the Cone.

Signed at Seattle, day of May, 1920.
