s'm'ras RUDOLPH JURGEBTSON, F BOSTON, MASSACHUSETT$ BEFLECTOE- EEADLIGHTS Application filed August 21,

This invention relates to an improvement .in reflectors for automobile and other headlights.

The object of the invention is to provide a reflector which will effectively direct rays of li ht from an automobile or other headlight, a greater portion of said rays of light being reflected forwardly in a horizontal direction; still other rays of light being reflected forwardly and downwardly upon the ground in front of the headlight and a limited number of other rays being reflected forwardly and downwar ly to the sides of the headlight.

The invention consists in a reflector for headlights as set forth in the following specification and particularly as pointed out in the claims thereof.

Referring to the drawings:

Figure 1 represents a front elevation of the reflector embodying my invention.

Fig. 2 is a central vertical section through the reflector taken on the line 22 of Fig. 1.

Fig. 3 is a central horizontal section through the reflector taken on the line 33 of Fig. 1.

Fi 4 is a detail section taken on the line lt of Fig. 1.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 5 represents a reflector which may be formed in any suitable manner from sheet material.- Viewed from the front, the reflector 5 is circular in form and has a flange 6 extending entirely therea round, and said reflector may be held within; any suitable form of headlight casing in any suitable manner.

A greater portion of the area of the reflector 5 comprises a parabolic portion having a reflecting surface 7 from which the rays of light fr an electric light bulb 8 will be thrown forwardly in a horizontal direction pro 'iding the electric light bulb is properly focused. The electric light bulb 8 is mounted in a socket 9 provided therefor and positioned upon the longitudinal median line of the reflector.

Located a suitable ght hull) 8 is a distance above the elecplane reflecting surface Serial No. 301,107.

which extends from the front of the reflector rearwardly and downwardly at a slight angle to the longitudinal median line of the reflector. The plane surface 10, furthermore, tapers at its opposite sides at 11 as it extends rearwar ly. At the rear of the reflector the plane surface merges into a curved surface 12 which continues downwardly to the center of the reflector. The reflecting surfaces 10 and 12 are provided for the purpose of reflecting rays of light forwardly and downwardly upon the ground in front of the headlight.

Located below the longitudinal median line of the reflector and extending down wardly and forwardly from the lower side of the socket 9 is a ridge 13 having flat inclined sides 14 adapted to reflect rays of light forwardly, downwardly and toward the sides of the headlight.

Also extending radially from the center of the reflector are two other ridges 15 which are shorter than the ridge 13, and these ridges 15 have reflecting surfaces 16 upon their lower sides that are adapted to refleet certain of the rays of light forwardly ant dowi'iwardly and toward the sides of the headlight.

As a greater portion of the area of the reflector 5 is constructed to provide a parabolic reflecting surface, a greater portion of the rays of light from the electric light bulb 8 will be reflected forwardly as a solid beam of light, providing the electric light bulb is located at the focal point of the reflector. .Qhe rays of light that strike the plane and. reaiwvardly inclined surface 10 and the curt "l surface 12 will be reflected forwardly and downwardly a short distance in front of the reflector and a relatively small num- I ber of rays of light striking the ridges 11. 3 and will be reflected forwardly, downand toward the sides of the reflector way at the sides thereof.

a ue L \aa. lighting the res I claim:

1. A reflector for a headlight having, in combination, a main parabolic reflecting surface, a plane downwardly and rcarwardly inclined reflecting surface above the axis of reflector and intersecting said parabolic surface, and a plurality of ridges having flat inclined sides projecting outwardly from the parabolic reflecting surface below the axis of the reflector and adjacent to the central portion of the reflector and adapted to reflect rays of light emanating from a source of light at the focal point of the reflector downwardly toward the front and sides.

2. A reflector for a headlight having, in combination, a main parabolic reflecting surface, a plane downwardly and rearwardly inclined reflecting surface above the axis of the reflector and intersectin said parabolic surface, and a plurality 0 inverted V- shaped ridges having flat sides and extending radially from the central portion of the parabolic reflecting surface below the axis of the reflector and adapted to difluse rays of light emanating from a source of light at the focal point of the reflector and direct the same downwardly toward the front and sides.

In testimony whereof I have hereunto set my hand.

RUDOLPH J URGENSON.
