HEADLIGHT.

Application filed September 30, 1925'. Serial No. 59,616.

To whom t may concern.'

Be it -known that I, ANTON F. Kimni'cnii, a citizen of the United States, residing lat Baltimore, in the county of Baltimore City 5 and State of Maryland, have invented a new and useful Headlight, of which the following is a specification.

By way of explanation, it may be stated that most automobile lam s, as at present constructed, are so made t at they tend tok cast a glare into the eyes of approaching pedestrians, and into the eyes of drivers of approaching vehicles. n s The foregoing being understood, .it is the object of the invention to provide a reiiector for an automobile lamp, so construct- 'ed that the rays of light will be thrown downwardly and forwardly upon the gound, thereby avoiding any objectionable g are. The glare proceeds, for the most part, rorn the lower portion ofthereflector of the headlight, and this invention aims to. vso construct the lowerpart of the reflector, that the same will cast theV rays backwardly yand upwardly upon the upper half of the reflector, the rays being thence reflected downwardly andV forwardly upon the ground, in such a way that there will be no undesirable glare. It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which thev invention appertains.

With the foregoing and other objects in view which will appear as the description proceeds, ,the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood thaty changes inthe precise embodiment of the invention herein disclosed, may beinade within the scope of what is claimed, withoutl departing from the spirit of the invention.

In the drawings Figure shows in y Ul ' vice constructed in accordance with the;in-'Y ventioii; and Figure 2 is a section m verticallyaboiit on the line 2--2 of by :the reference letter'A. is the top of the front elevation, a de-f ure l; Y e ,ively,

That parat of the reflector which is marked reflector, and the reflector must be placed accordingly, in order to operate properly.

The reflector forming the subject matter of this application comprises av cup-shaped.

body provided with upper and lower circumferential ribs, the inner` surface 2 of the foremost lower rib 3 having a backward and -outward slant, theinner surface 4 of the rearmost lower rib 5 having a forward and outward slant, land the inner surfaces 6 of the intermediatelower ribs 7 varying.

progressively, from Athe front of the body l toward theback thereof, kfroin a backward and outward slant, to a forward and outward slant, all of said surfaces being so located as to reect yupwardly upon the innersurfaces V8 of the'upper ribs 9, the said inner surfacesl 8 of the upper ribs 9 being rearwardly and inwardly inclined, to reflect downwardly and forwardly the rays received from the inner surfaces 2'and 6 of the lower ribs. Y

The device is so constructed that the rays :proceeding from the source 1l of light. will be thrown downwardly and forwardly, the

source 11 ybeing an electric lamp, or any other kind of a lamp, disposed axially with respect to the body 1.

The reflector is further characterized by the fact that the forward surfaces 10 of the lower ribs slant backwardly and outwardly beneath thelower ribs, so that those surfaces will not throw the rays proceeding from the source 11 of light, into the eyes of those approaching the device, and, furthermore, the said surfaces 10 are so disposed with respect to the surfaces 8 of the upper ribs, that the surfaces 10 will not receive and reflect forwardly, rays derived from the said surfaces 8. v

What is claimed is c 1. A reflector comprising a cup-shaped body provided with upper and lower circumferential ribs, the inner surface of the foremost lower rib havingabackward andV outward slant, the inner surface ofthe rear-1 most lower rib having a forward and outward slant, and the -innersurfaces ofv theY intermediate lower ribs varying progressfrom the front of the body toward the back thereof, from a backward and outward slant to a forward and outward. Slant, all

of said surfaces being,I so located as to refleet upwardly upon the inner surfaces of the upper ribs, the Said inner surfaces of Jche upper ribs being rearwardly and inwardly inclined, to reflect downwardly and forwardly the rays received from the inner surfaces of the lower ribs.

2. A reector constructed as set forth in claim l, and further characterized by the fact that the forward surfaces of the lower 10 ribs slant backwardly and outwardly beneath the lower ribs.

In testimony that I claim the foregoing as my own, I have hereto aixed my signature.

ANTON KRALICEK.
