UNITED STATES ALBERT J. WALKER, OF HAMILTON, ONTARIO, CANADA HEADLIGHT Application filed May 23, 1929. Serial No. 365,328.

This invention relates to improvements in headlights.

One important object of the invention is to provide an attachment for headlights adapted to prevent the glare common in such devices while at the same time giving full road illumination.

A second important object of the invention is to provide a novel attachment for headlights adapted to prevent glare and which may be folded for packing in a flat form or may be readily erected for setting up in the headlight.

With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

In the accompanying drawings like characters of reference indicate like parts in the several views, and:

Figure 1 is a longitudinal median section through a headlight equipped with this invention.

Figure 2 is a front view of such a light.

Figure 3 is a perspective view of the attachment set up in the shape it assumes in the lamp.

Figure 4 is a section just back of the ex treme forward edges of the partitions forming this attachment, the partition being shown folded in shape for storing.

Figure 5 is a detail showing the method of connectin the two partitions used herein.

In the em odiment of the invention here shown there is disclosed an ordinary headlight casing 10 wherein is mounted a reflector 11 having at its front or open end a lens 12 held on the casing by the locking ring 13. At the rear of the reflector 11 there is provided a lamp socket 14 for the reception of a lamp 15 having a shank or neck 16. The usual wiring connections 17 are also provided. The attachment itself consists of two plates 18 and 19, each having a straight front edge and arcuate rear edge portions 20 conforming to the shape of the reflector 11 and separated from each other in each plate by a notch 21 shaped to fit around the lamp 15 and against the shank 16 and socket 14 as clearly shown in Figure 1. One of these plates, as 18, has a slot 22 leading forwardly from its notch 21 while the other plate has a corresponding slot 23 leading rearwardly from its rear edge. In the slot 22 is fitted that portion. of the plate 19 which lies between the slot 23 and notch 21 and correspondingly that portion of the plate 18 which lies between its slot and its front edge is fitted in the slot 23. Now, these plates are made of thin metal such as tin or the like and preferably have somewhat dull surfaces so that they effectually sto the glare caused by improper reflections. oreover, by reason of their being made of thin metal they may be folded into fiat position as shown at Figure 4 for storage or transportation or set up as disclosed in the other figures. Moreover, this folding arrangement makes it easy to apply the attachment to the headlight because the plates may be folded as in Figure 41-, slipped into position in the reflector while the lens is off and easily positioned around the lamp. Then by spreading them at angles to each other and replacing the lens they will be held securely in position. It is to be noted that While these plates have here been shown as arranged at right angles they may, if desired, be positioned for use at any other angles.

There has thus been provided a simple and efficient deviceof the kind described and for the purpose specified.

It is obvious that minor changes may be made in the form and construction of the invention without departing from the material spirit thereof. It is not, therefore, desired to confine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new, is:

1. The combination with a headlight reflector; of a pair of partitions intersecting each other at right angles and fitted in the reflector with the line of intersection coaxial with the reflector, said partitions being connected to fold fiat one on the other throughout their extent.

2. The combination with a headlight reflector; of a pair of partitions intersecting 5 each other at right angles and fitted in the reflector with the line of intersection coaxial with the reflector, said partitions being connected to fold flat one on the other throughout their extent, said partitions bein pro- 10 vided with notches in their meeting e ges to fit around a lamp mounted in said reflector.

3. The combination with a headlight reflector; of a pair of partitions having identical outlines and curved at their rear edges 15 to fit the curve of the reflector, said partitions being pivotally connected on their central lines to fold flat, one upon the other.

4. The combination with a headlight reflector; of a pair of partitions having idengo tical outlines and curved at their rear edges to fit the curve of the reflector, each of said partitions having its rear central portion provided with a notch shaped to fit around a lamp bulb and against opposite sides of a 25 lamp socket, one of the partitions having a slot extending forwardly from said notch and the other partition having a slot extendin rearwardly from its front edge, each of sai slots receiving the part of the other an partition in alinement with its slot whereby said partitions may be positioned at desired angles to each other and one fiat on the other.

In testimony whereof he has aflixed his as signature.

ALBERT J. WALKER.
