NONGLARE SHIELD FOR HEADLIGHTS Filed D60. 31, 1927 w, l///////// g/ a K 1 i i i Patented Dec. 17, 1929 UNITED STATES PATENT OFFICE NONGLARE SHIELD FOR HEADLIGHTS Application filed December 31, 1927. Serial No. 243,883.

This invention relates to those devices which are adapted to be applied to the headlight of an automobile, to the rear of the lens and in the lower part thereof, for the purpose of obstructing, or so deflecting, the rays of light from the lower part of the reflector that glare will be prevented.

The object of the invention is to provide a simple, inexpensive, light and durable nonglare shield of this general character which will embody improvements whereby it may be secured in position by the headlight bulb alone, or, if the type so requires, be secured by the electric bulb and the rim of the headlight, without necessitating the use of screws,

bolts, or other fastening devices.

The present non-glare shield is made from a single piece of sheet material, either of cloth, paper, fiber, composition, or metal.

Preferably, aluminum will be used because of its strength and lightness but I do not limit the invention in that respect.

The shield may be imperforate, except at its ends where it is provided with holes for its attachment, or it may have a considerable number of perforations, serving to allow some of the rays of light to pass through and to prevent overheating.

In the following description, and in the drawings, disclosure is made of the two forms the shield may assume, according to the type of lamp on which it is used but the blank from which the shield is made is the same in both instances, the different shapes resulting from bending the blank so that it will be solely held by the lamp, or, on the other hand, be arranged with its ends in engagement with the lamp and with the rim of the headlight.

In the accompanying drawings:

Figure 1, is a vertical section through an automobile headlight, showing one way in which the shield may be arranged;

Fig. 2, is a similar view showing another manner of arranging the shield;

Fig. 3, is a front elevation, the shield being arranged as shown in Fig. 1;

Fig. 4, is a face view of the blank, dotted lines showing the crease where the blank may be folded or bent to assume either of the.

forms shown in Figs. 1 or .2; and

Fig. 5, is a similar view illustrating the use of perforations in the shield.

The blank from which the shield is made, whether of cloth, paper, fiber, composition, or metal, is originally of the shape shown in Fig. 4, being provided with a body 1 of more or less sector-shape and a neck or stem 2. The neck and the end of the body 1 are provided with holes 3, 4, respectively, said holes being of a size adapting them to receive the neck of the usual headlight electric bulb 5 so that when the bulb is secured in its socket 6, one, or both ends of the shield may be anchored, according to the type of lamp 7, 8, Figs. 1 and 2, on which the shield is used.

The body 1 maybe imperforate, as shown in Figs. 1 to 4 or it may be provided with a considerable number of perforations 9 as shown in Fig. 5.

According to the type of lamp, and, more particularly, the shape of the reflector 10, 11, thereof, the shield will be secured by the bulb 5 at one end and by the lens ring 12 at its lower end as shown in Figs. 1, 3, or, both ends of the shield will be secured by the lamp as shown in Fig. 2. l/Vith that end in view, the shield is provided with a transverse crease 13 extending across the body 1 so that a well defined angle or horizontal ridge 14 will appear just back of the lens 15 when the shield is arranged as shown in Fig. 1 or as in Fig. 2.

In each instance the shield is in more or less folded condition, the fold being defined by the crease 13 and ridge 14.

lVhether the shell be used as shown in Fig. 1 or in Fig. 2, there is provided a horizontally disposed part 16 below the bulb 5 which cuts off those rays of light which cause a headlight to exhibit glare to a driver or person in front of the headlight.

According to the type of headlight, the shield may be arranged in either of the two ways illustrated in Figs. 1 and 2. When it is arranged as shown in Fig. 2, the neck of the bulb 5 will pass through both of the holes 3, 4. WVhen the shield is arranged as in Fig. 1, the neck of the bulb 5 will only pass. through hole 4, the neck 2 having the hole 3,-th.en being bent as shown at 17 and clamped between the shell of the headlight and the rim 12.

The material of which the shield will be made, will have such stiffness, although of inherent flexibility, that it will retain itself in position without requiring fastenings of any character.

I am aware that the invention is susceptible of modification; therefore, I do not limit myself to the specific embodiments disclosed, except as stated in the'elaimsv l What I claim is: I

1. An attachable and detachable non gl-are V shield for automobile headlights, comprising a single strip of flat material bent or folded intermediate its ends to provide'an upper part which is concaved on its-upper, face so that said facewill throwtherays oflight upwardly against the upper part of the headlight reflector when the shield is in position on the. headlight, and a lower part joined to the front edge of the upper partfalong. the

line on which the strip is bent, or fo1ded ,"the opposite. ends of said shield being formed for engagement by the headlight itself with;

out requiring special fastening means, when the-shield is in position inia headlight, v

2. The combination with the reflector and lamp of a headlight, of an attachable and de tacha'ble non-glare shield comprising a single strip of flat material bent or folded intermediate its ends toprovide an upper. part;

' which is arranged in general lateral position below the lampand adapted ttithrow the rays of light upwardly against the upper part of. the headlight reflector, and a lower part joined toithe front edge ofthe upperpart along the line on which the strip is bent or folded, both ends of said shield being formed so that the shield is engaged and held by the headlight itself withoiltrequiring special fastening means.

In testimony whereof I aflix my signature.
