ahead, and permits the vehicle to be safelyv driven at a high speed. When the vehicle enters avillage or city where lower speeds are the rule, the driver should close the switch 13 and open switch 12 for extinguishing the lamp 6 and for lighting the lamp 8'. As the lamp 6 is disposed in the lowermost or deepest compartmententirely beneath the partition 7, the broad horizontal apron 7,
restricts the direct rays ofthe lamp 6- to the level of the axis of said lamp, which is rarely ever more than three feet from the level of the roadway. The light from the lamp 6 is thus projected a shorter distance than that of lamp 6, and the drooping apron 7' tends to deflect the greater portion of the bright rays of lamp 6' downwardly, so that drivers of other vehicles, as well, as pedestrians cannot see any glare. By this dise position and arrangement of the lamp 6, the whole breadth of the roadway is brightly lighted for a safe distance, and the approach and course of the vehicle may be readily observed withont its headlights producing the usual dazzling efiect.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is-
1. Ann-glare head-light, including a conical reflector having a closed end arranged in vertical plane and provided with a reflecting surface, said reflector being formed with interior oi the a plurality of wedge-shaped plane surfaces which taper from its open end to its plane end, a pair of electric lamps supported by said plane end, and a partition dividing the reflector horizontally and separating said lamps, the free end of said partition declining forwardly for restricting the rays of the lowermost lamp to the level of the horizontal axis of said lamp, and the top and bottom surfaces of said partition being polished for reflecting the rays rem the corresponding lamps.
2. In a nolare head-light, the combination of a re ector comprising a frustum whose reduced end is closed and arranged in vertical plane, a pair of lamps disposed one above the other in said reflector and supported by its reduced end, a light reflectin partition joined to said plane end and subdividing the reflector into upper and lower compartments, 'a portion of said reflector comprising a forwardly declining apron whose free edge is disposed in a horizontal plane on a level with the axis of the lowermost lamp, and means for alternately lighting said lamps.
3. The combination of a bell-shaped reflector, the reduced end thereof being closed and disposed in vertical plane, a pair of electric lamps disposed one above the other and supported by "said closed end, a partition separating said lamps and dividing said reflectors substantially on the line of its horizontal axis, the forward end of said partition disposed at an angle which positions its free edge in line horizontally with the axis of the lowermost lamp for restricting the rays of said lamp for the full breadth. of the reflector to the height of said line. Y i
In testimony whereof I affix my signature.
