WALTER DARCY RYAN, OF SCHENECTADY, NEW YORK.
, HEADLIGHT.
Application fll ed July 24, 1922. Serial No. 576,911. 7
To all whom 'it may concern:
.' Be it known that I,-WALTER -DAnor RYAN, a citizen of the United States, residing at Schenectady, in the county of Schenectady and State of New York, have invented a new and useful Improvement in Headlights, of -which the following is a specification. 4 My invention relates to headlights and i 10 has for .its object to provide new and improved means for fusing from a single light source the rays to light the roadway far in advance of the vehicle 'to which it is attached, and also the closely immediate surroundingsc A further'object is to provide means to redirect downwardl' and outwardly' a certain portion of. the ightrays which would otherwise escape outwardly and upwardly from the source, so it can be utilized to illuminate an area close to the vehicle.
By reference to the accompanying draw ing and reading of the following description a person skilled in the'art will readily understand the construction by which' I accomplish the desired objects. Flg. 1 is a cross sectional *Fig. 2 is a front View. 7 a I In the drawing the reference numeral 10 indicates the headlight housing,11 the reflector, 12 thelamp and 13- removable glass containing casingfront. ,The lamp 12 is mounted on an elongated shaft support 14 side elevation.
which causes it tojbe positioned in advance I of the housing, and the glass front 15 is provided with a protruding center portion 16 into which the lamp projects, asshown. The protruding portion 16 is preferably constructed with prisms on its upper half L to project the major portion of the light rays received thereon downwardly and outwardly.
I By this construction the light rays from the lamp which impinge on the reflector 11 are directed forwardly through the glass front, in a long beam to light the roadway far in advance of the machine, and therays which come direct from the lamp through the glass front (except those impinging upon the upper part of the protruding portion 16) illuminate the immediate surrounding to the lamp mounting, while a large portion of those rays that strike the upper part of the protruding portion 16 are redirected downwardly and outwardly immediately in front of the vehicle. The upper part of the protruding portion may, if desired, be sand-blasted, or provided with any diffusing means'in preference to the prisms 16.
The protruding portion into which the lamp projects may be formed by molding 'its central portion protruding outwardly from the plane o'fftheouter surface; the 75 positioning of the light source being such that it extends into the protruding portion of the lens, the upper surface of said protruding portion being provided with refracting means to redirectlight rays impinging thereon, outwardly and downwardly.
In testimony whereof I have signed the foregoing specification.
WALTER DARCY RYAN.
