PATENT OFFICE.
LOUIS DUIEK, OF SEATTLE, WASHINGTON.
HEADLIGHT Application Med June 19.
To all whom it may concern:
Be it known that I, LOUIS Durex, a c tizen of the Czechoslovakia Republic, residing at Seattle, in the county of King and State of. Washington, have invented" certain new and useful Improvements in Headh ht Reflectors; and I do hereby declare the ollowin'g to be a full, clear and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same. a
The object of this-invention is the prov sion of a reflector for hea'dli hts which while projecting the rays of lig w ll obviat e glare and the consequent blinding of the'driver of an approachlng vehlcle.
A further object of the invention is to provide a reflector which will modify the light and soften and mellow the rays thereof to obviate the blinding glare which 18 prolific of casualties, annoyances and discomfort.
In accordance with the present invention the surface of the reflector is corrugated and of contrasting. color, the crests of the corrugations and the valleys between the corrugations being of difl'erent colors which blend so as not to leave any line of demarcation.
Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.
While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the in vention.
Referring to the accompanying drawings forming a part of the application:
Figure 1 is a reflector embodying the invention,
Figure 2 is a sectional view thereof on the line 22, and
Figure 3 is a diagrammatic sectional view.
Corresponding and like parts are referred to in the followin descr1ption and designated in the severall views of the drawings by like reference characters.
The reflector illustrated may be of any construction and design such as generally fluted, as indicate REFLECTOR.
1983. Serial No. 646,413.
provided for headlights and in accordance with the present invention, the outer or marginal portion 1 of the reflector is lain as well as the central portion 2. owever, the intermediate dportion is. corrugated or mostclearly in Figure 3, the outline of the corrugations being of any preferred configuration. In the preferred arrangement, the corrugations 3 have a radial disposition and their terminal portions mer e into the plain surfaces 1 and 2. The outline of the corrugations is more pro nounced at a central point and tapers or vanishes towards opposite ends into the plain surfaces 1 and 2. -These corru atio'ns result in difi'usin'g the rays of light, t ereby obviating the blinding glare and the light is further softened and mellowed by having the crests of the corrugations 3 and the valleys' between the corrugations of contrasting color and, in practice, the best results are obtained by having .the portions between the corrugations green and the crests of the corrugations white, and these colors blend or vanish so as not to leave any line of demarcation or distinction.
A reflector constructed in the manner herein indicated will effectively illuminate the roadway ahead of a vehicle without shedding rays of light of a glaring or blinding nature which is objectionable.
What is claimed is:
'1. .A reflector having its surface corrugated and the crests of the corrugations and the valleys therebetween of'contrasting colors adapted to blend in combination with a source of artificial light so as toobscure lines of demarcation between the colors.
2. A headlight reflector having its center and marginal portions plain and the intermediate portion radially corrugated, the corrugations vanishing at opposite ends into the plain surfaces and the crestsof the corrugations and the valleys therebetween be- In testimon whereof I afiix-my signature in presence 0 a witness. v LOUIS DUFEK.
