Description

Feb. 16, 1932. A ALLIS ANTIGLARE SHIELD Filed Sept. 11, 1929 Patented Feb. 16, 1932 UNITED STATES mm. ALLIS, or MILWAUKEE, Wisconsin ANTIGLABE SHIELD Application filed September 11, 1929. Serial No. 391,968.

My invention refers to anti-glare shields, particularly designed for automobile or motor-boat lights, but obviously they may be used for lights in connection with various types of vehicles, other than those mentioned.

The particular obg'ect of my invention is to provide a spider orm of hood of the radial type, adapted to encase a lamp whereby the rays are diifused and will thus prevent blindness or glare to the eyes of parties coming in the direct field of the lamp.

l/Vith the above and other objects in view, which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claim, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.

In the drawings, Figure 1 represents a standard form of automobile headlight, with arts broken awa and in section, the same 2t eing equipped with a shield embodying the features of my invention;

Figure 2 is a face view of the same; and

Figure 3 is a side elevation of a lamp showing the application of another form of my invention thereto.

Referring by characters to the drawlngs,

1 represents the outer hood of a lamp, and 2 the concave metallic reflector having mounted centrally thereof a lamp bulb 3. i

The periphery of the hood is formed with a threaded band for the reception of a correspondingly threaded base band 4: of antiglare shield embodying the features of my invention. The band in this instance is integral with a plurality of radial spokes 5,

which are of sufficient width to constitute deflectors, their inner surfaces being preferably of reflective material.

As noted in Figure 1 of the drawings, the spokes are convex in form and positioned a proper distance in advance of theabulb, whereby the rays of light from said bulb will strike the inner surfaces of the spokes and thus break up ra s which will be indirectly reflected through the apertures formed between the spokes and also through a central circular hub aperture 5. t

Figure 3 of the drawings illustrates another form of my invention, to be used in connection with the standard light or hood 1. In this form, which is more cheaply constructed, the band 4 of the shield has extending rearwardly therefrom a plurality of spring clips 6, the ends of which are bent to conform to the surface of the lobe 3. Thus, it will be seen that the shield can simply be snapped into position with relation to the bulb and is held in such position by the yielding grip of the clips 6.

It will be noted that the spokes of the shield in either form of my invention are preferably of the Maltese cross type, but obviously I may vary the form without departing from the spirit of my invention, the essential elements of which are the arrangement of the radial spokes of predetermined Width to form reflectors havlng a circular apertured hub through which the light may be difi'used in conjunction with the light that is diffused between the spokes. By this arrangement in practice, the light is so broken up that a party coming in the direction of the lamp will not be blinded by rays, but the light will be diffused softly so that it can be readily looked into and at the same time the rays from the lamp are not unnecessarily dimmed.

While I have shown two methods of applying the anti-glare shield to lamp hoods of standard design, it is obvious that I may vary the means of attachment without departing from the spirit of my invention.

I claim:

As a new article of manufacture, an antiglare shield for headlights comprising a body formed from a single sheet of material having an annular rearwardly directed supporting flange, forwardly and inwardly extending arcuate arms connected with the flange and merging together at the axial center of the body, said merged portion of the arms being provided with an enlarged axially arranged opening.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin.

AMBER ALLIS.
