Specification of Letters Patent.

Patented Jan. 9, 1917.

Application filed March 16,1916. Serial No. 84,563.

To all whom it may concern:

Be it known that I, WILLIAM 0. PAUL, a

'citizen ofthe United States, residing in the city of Newark, in the county of Essex and State of New Jersey, have invented certain.

in cost, comprising a minimum number ofparts, the lamp giving forth a powerful shaft of light, the top of which is level with the top of the opemng in the front of the casing, and which from that elevation extends forward and downward to the road, spreading laterally to the desired degree, and being of a length that is entirely adequate for urposes of safety and convenience, said shafi: of light having in it no upwardly directed rays capable of being cast into the eyes of persons approaching from the opposite direction. a

With this end sists in certain novelties of construction and arrangements of parts, as hereinafter set forth and pointed out in the claims. While the preferred forms of my invention are illustrated in the accompanying drawings, yet it is to be understood thatv minor detail changes may be made without departing from the scope thereof.

In the accompanying drawings, Figure 1 represents a front elevation of a lamp embodying my invention; and Fig. 2 represents a vertical central section taken on line a2-a2 of Fig. 1. d

Similar numerals of reference refer to like parts throughout the specification and draw- In the drawings, the lamp casing is illustrated as consisting essentially of two parts,

namely, the base 1 and the hood 2 secured thereto along the line 3, in any desired or convenient manner. Secured to the front of in view, my invention cont the hood in any suitable manner is a bezel 4 of any desired or convenient shape.

The illuminating means of the lamp is located in the base 1 of the lamp, and comprises an incandescent globe 5, a filament 6 and the socket 7. The filament 6 may be connected to any suitable source of electricity, such as for instance, the batteries usually carried by an automobile.

The construction of the base as clearly indicated in the drawings is in the form of a parabola, the interior surface of which is preferably highly polished, and the axis of the parabolic base is inclined rearwardly from the perpendicular, in order that the rays cast-by the incandescent lamp will be cast upon a preferably polished interior surface of the hood 2, and be projected by said surface of the hood 2 forward and downward, so as not to be cast into the eyes of persons facing the lamp. The hood 2 in its preferred form, consists essentially of an elbow, with a flattened portion as indicated at 8, said flattened portion having a reflecting surface, prefera 1y highly polished, in order to receive and reflect the rays cast by the light upon the parabolic surface,

of the base 1.

As illustrated in Fig. 2 of the drawings, the hood 2 may consist of an unbroken curved surface, as indicated in dotted lines, in which case, the flattened portion 8 of the hood 2' may be' dispensed with, and the curved surface being polished and utilized to receive the reflected light from the parabolic base. 1, and in turn be cast by said surface downward and outward upon the roadway.

The present invention provides I a very eflicient and exceedingly simple lamp, the

' and combinations of parts as herein shown and described, as obvious modifications will suggest themselves to those skilled in the art.

I aving thus described my invention, what I desire to secure by Letters Patent is 1. A non-glaring lamp for vehicles comprising a casing having a light outlet opening, a reflector behind said opening inclined rearwardly and downwardly from adjacent the top of said opening to substantially the bottom of" the opening, and a concave reflector mounted below said opening and adapted to project light upwardly and rear- \varclly upon the inclined reflector.

wardly and extending from the top to substantially the bottom of said opening, and a paraboloidal reflector mounted wholly below'said opening and adapted to project light rearwardly and upwardly upon the inclined reflector.

4. A non-glaring lamp for vehicles com; prising a reflector casing having a circular light-emitting aperture, said reflector casing behind said aperture being inclined from a point adjacent and on one side of said aperture rearwardly across the axial line of said aperture and formed into a substantially flat reflecting surface, said reflector casing being formed on the opposite side of said aperture into a paraboloidal reflector mounted wholly on one side of the aperture and with its axis inclined rearwardly from the perpendicular to the axial line of said aperture.

This specification signed and witnessed this 14th day of March, 1916.

WILLIAM C. PAUL.
