ANTIGLABE AND LIGHT-DISTRIBUTING MEANS FOR, VEHICLE HEAD LAMPS.

Application filed April 8,

My invention relates to an antiglare and light distributing means for vehicle headlamps, and the objects of my invention are:

First, to provide such a means whereby the luminous filament of the bulb of the headlamp, which causes a disagreeable and dangerous glare, is substantially concealed from the front of the headlamp. Second, to provide a ineans'of this class whereby the direct rays and also the reflected rays, from\ the vehicle reflector, directed to the sides thereof, are intercepted and modified by my antiglare and 'light distributing means.

Third, to provide a means. of this class whereby the direct and reflected rays of light directed against my headlamp means appear to be substantially uniformly distributed over the' whole front. opening of the head lamp, thus modifying the force of the light. Fourth, to provide a means of this class which may be easily and quickly positioned in headlamps now in use. Fifth,.to provide a novelly constructed antiglare and light distributing means for vehicle headlamps, and sixth, to provide ameans of this class which is very simple and economical of construction, durable, eflicient, and which will not the frame and the lens part1 readily deteriorate or get out of order.

With these and other objects in view, as will appear hereinafter, my invention consists of certain novel features of construction combination and arrangementof parts and portions, as will-be hereinafter described in detail and particularly set forth in the appended cla1ms,' reference being had to the accompan ing drawings and to the characters of reerence thereon, which form a part of this application, in which:

Figurel is a lon itudinal sectional view of a conventional ve icle headlamp with my means positioned therein with the section taken through 1-1 of Fig. 2, also showing certain parts and portions in elevation to facilitate the illustration. Fig. 2 is a front elevational view thereof with a portion of broken away and in section to facilitate t e illustration. Fig. 3 is an enlarged, fragmentary sectional view of a slightly modified form of construction of the means for supporting the device within the headlamp. Fig. 4 is a longitudinal sectional view of a conventional vehicle headlamp witha slightly modified form of certain parts and portions in elevation to fa- 1925. Serial No. 21,525.

cilitate the illustration, the section being taken through 4=--4= of Fig. 5 and Fig. 5, is a front elevational view thereof with a portion of the frame and lens of the headlamp broken away and in sectionto facilitate the illustration,

' Like characters of reference refer to similar parts and portions throughout the several views of the drawings. y

The headlamp housing 1, reflector 2, bulb 3, central shield 4, bands 5, supporting members 6, and the lens 7 constitute the principal parts and portions of my antiglare and light distributing means in one form of construction.

My antiglare and light distributing means is preferably loosely positioned within the parabolic reflector 2, positioned within the headlamp housing 1 and against the lens 7 of the headlamp. Said means, in the preferred form of construction as shown in Fi s. l and 2 of the drawings, is-provided at t e middle portion with a'parabolically shaped supports 6 are "bent backwardly and curved,

to conform substantially with the outer portion of the reflecting surface of the reflector- 2. Positioned around the shield 4 and spaced therefrom and from each other are a plurality of concentric reflecting bands 5, which are secured to the supports 6 preferably by solder. The outer concentric bands 5 are respectively positioned forwardl from theinner ones so that no part of the ulb can be seen from the outside of the headlamp. Said bands are preferably coated with a white paint or enamel so as to modify the light issuing therefrom. The lens 7 of the headlamp is also preferably frosted so as to still further modify the intensity of direct reflected rays and tomore uniformly distribute the li t.

In the modified form of construction of the supporting means, as shown in Fig. 3 of the drawings, the supports 6, supporting the concentric bands 5 and the shield 4, extend to the outer periphery of the lens 7 and the same, substantially as shown in are bent backwardly over the outer ed e 0g 1g. of the drawings, so that the device does not produce unnecessary wear on the reflector of the headlamp and also so that the same may be removed when removing the lens for replacin bulbs of the headlamp.

In t e modified form of construction of my antiglare and light distributin means, as illustrated in Figs. 4 and 5 of t e drawings, the shield 4, similarly positioned within the headlamp housing in front of the bulb 3, as in the preferred construction, is provided with a convex reflecting surface 4', which convex reflecting surface faces the bulb, positioned within the headlamp, and

.reflects the direct rays toward the main reflector 2. Said shield is preferably secured at its edges to the inner portion of the inner light distributing band 5. The bands 5 in the modified form of construction are also positioned in concentric order but are of greater width and positioned in substantialy the same vertical plane. The inner edges of the bands are secured to the supports 6 which are positioned against the lens with their outer ends extending over the edge thereof.

It is obvious from this construction, as illustrated in the drawings and disclosed in the foregoing specification, that there is provieded a means for modifying the lare 3.111,. uniformly distributin the rays 0 light of vehicle headlamps, an though I have shown and described a particular construction, combination and arrangement of parts and portions and certain modifications thereof, I do not wish to be limited to this particular construction, combination and arrangement nor to the modifications but desire to include in the scope of my invention the construction, combination and arrangement "substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is: v

1. In a device of the class described, the combination with a conventional headlamp and reflector, of supports positioned near one end of said reflector, a solid curved shield positioned in axial. alinement with said reflector and supported by said supports and a plurality of bandspositioned around said shield and spaced therefrom and sup ported by said supports.

2. In a device of the class described, the combination with a reflector of a headlamp and a bulb positioned therein, of a shield positioned within said reflector in front of said bulb, a plurality of angular supports radiating outwardly from said shield towards the open edge of said reflector, and a plurality of bands s aced from eachother and supported by sai an ular supports.

3. In a device of t e cla'ss described, the combination with a reflector of a headlamp and a bulb positioned therein, of a shield positioned within said reflector in front of said bulb, a plurality of angular supports radiating outwardly from said shield towards the open edge of said reflector, and a plurality of concentric annular bands spaced from each other and from said shield and supported at their front edges on said supports. 1

4. In a device of the class described, the combination with a conventional headlamp, of a shield positioned in front of and spaced from the bulb positioned therein and a plurality of supporting members secured at one end to said shield and radiating angularly therefrom, their other ends being positioned contiguous to the openin of said reflector.

5. In a device of the c ass described, the combination with a conventional reflector of of a headlamp and a bulb positioned therein, of a shield positioned within said reflector in front of said bulb, supports extending outwardly from said shield toward outwardly beyond the headlamp directly from the reflector.

6. In a device of the class described, the combination with a conventional reflector of a head lamp and a bulb positioned therein of supports positioned near one end of said reflector and extending inwardly and backwardly on an angle therefrom and a plurality of concentric annular bands spaced from each other and in front of said bulb and secured to said supports at their front edges.

7. In a device of the class described, the combination with a reflector and lens of; a conventional headlamp, of radiating sup ports loosely positioned at their extended ends at the outer end of said reflector and in engagement with the lens, and a solid curved shield positioned in axial alignment with said reflector and supported by said supports at their central portion.

In testimon whereof, I have hereunto se my hand at 25th day of March, 1925.
