1 Claim.

This invention relates to improvements in headlights.

The principal object of this invention is to produce a headlight whereby the glare would be eliminated.

A further object is to produce a device of this character which may be employed with the ordinary motor vehicle without altering its construction A further object .is to produce a device of this character which is neat in appearance, economical to manufacture and one which will comply with the ordinary State requirements.

Other objects and advantages will be apparent during the muse of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a front elevation of my headlight; and

Fig. 22 is a cross sectional view taken on the line 22 of Fig. 1.

Automobiles in approaching each other at night often employ headlights which are blinding to the driver of the other car. This blinding of the driver very often causes serious accidents. It is to avoid this difficulty that I have devised my headlight.

In the accompanying drawing wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 desi nates a shell which may be circular in cross section when viewed from the front, or may be the shape shown in Fig. 1, that ,is the side walls of the front portion of the shell are of greater height than the width of the top and bottom walls thereof, and as shown in Fig. 2 the rear portion 6 has a reflector I therein.

The reflector 1 includes upper and lower concaved elements and the upper element is directed rearwardly and downwardly from the top'and side walls, while the lower element is reversely curved rearwardly and upwardly from adjacent the bottom and side walls and meets the rear end of the upper element slightly above the bottom wall. The forward portion of the lower reflecting element is curved upwardly and rearwardly and has its upper edge terminating above the juncture of the rear ends of the upper and lower elements, to provide a light well 8 which entirely faces the upper element, as clearly shown in Fig. 2.

Mounted in the Well 8 is a light bulb 9 that extends rearwardly at an acute angle to the longithe bulb will be reflected by the upper element,

parallel with the walls of the front portion, as

indicated by the dot and dash-lines in Fig. 2.

The interior of the front portionhas its surface H polished to provide a reflecting surface, and mounted in the front portion is an element l2 that has a nonreflecting upper surface and which may be painted black for that purpose. The eleinate the upward beam which would be otherwise objectionable.

By virtue of the black coated surface, all glare of the headlight, to the approaching motorist, is eliminated.

In other words, as a motorist or pedestrian 'draws near to my improved light, all danger of a confusing blinding ray is in reality reduced to a minimum.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material,

size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention I claim:

A headlight comprising a shell including a front portion having side walls of a greater height than the width of the top and bottom walls, a reflector in the rear portion of the shell and including upper and lower reflecting concaved elements, said'upper element being directed rearwardly and downwardly from said top and side walls, said lower element being reversely curved rearwardly and upwardly from adjacent said bottom and side walls and meeting the rear end of said upper element slightly above the bottom wall, said lower reflecting element having its forward portion curved upwardly and rearwardly and having its upper edge disposed above the juncture of the rear ends of said upper and lower elements to provide a light well entirely facing said upper element, a light bulb in said well and extending rearwardly at an acute angle to the longitudinal axis of the shell, whereby light rays from the bulb will be reflected by the upperelement parallel with said walls, and a non-reflecting element curved downwardly and forwardly from the upper edge of the well and disposed along said bottom wall and lower portions of said side walls to the forward end of the shell.
