ALBERT A. AszMAN, or RALI-IWAY, NEW JERSEY.'

LIGHT-DIMMER.

Application filed September 6, 1916. Serial No. 118,747.

To all whom it may concern:

Be it known that I, ALBERT A. a citizen of the United States, residln AszMAN, at

. Rahway, in the county of Union and tate of New Jersey, have invented new and useful Improvements in Light-'Dimmers, of

.which the following is a specification.

This invention relates to headlight dimmers, and has for its principal object the provision of a device of this character which may be expeditiously applied to any well known' form of head light such as that used posedin the line of projection of the light rays passing from the burner so as to soften the brilliancy of said light rays and thereby permit the head light to be used upon public highways without the objectionable dazzling eifect of the light upon the eyes of edestrians.

, other object of the invention resides in the provision of a device of this character which will consist of a foraminous body having a portion below its horizontal center provided with a relatively large opening,

the perforations in the body being closely related so as to cause an effective softening of the light rays and yet diffuse the same and eflectually cause the light rays to be scattered in a downward direction toward the mentioned opening where the surface of the highway immediately in advance of the vehicle will be properly illuminated.

With the above and other objects in view which will appearas the nature of the invention is better .understood, the same consists in the improved construction and novel arrangement of parts which will be hereinafter more fully described and particularly pointed out in the claim.

Inthe accompanying drawing, has been illustrated a preferred form of the invenvtion, it being however understood, that no limitation is necessarily made to the precise structural details therein, exhibited, but that changes, alterations and modifications within the scope of the claim may be resorted to i when desired.

Fig. 2, is a'rear elevation of the device removed from the head-light.

Fig. 3, is a similar view showing a slightly modified form of the invention.

Fig. 4:, is a horizontal the line 44 of Fig. 3.

The dimmer consists of a. foraminous body 1, which in the presentinstanceis consection taken on structed of sheet metal having the same uniform thickness throughout. The openings 2, which are formed in'the body are closely related to one another, providing intervening opaque portions of the body between the perforations. In thisimanner the material is rendered translucent and the light rays will be immediately obstructed on their passage from the burner of the 'head light.

The head light shown herein is a well known design and the dimmer is constructed so as to operatively accommodate itself directly at the rear of the lens carried by the usual swinging closure. In order that the lens may be securedin position in the opening of the head light closure lugs A are provided. The foraminous body 1, constituting the dimer is of a size whereby it will nicely accommodate itself to. the lens and completely extend over the same, being substantially translucentand the light rays will be difi'used and the sharp brillian'cy will be considerably moderated so as to eliminate the dazzling glare of light upon the eyes. The marginal edges of the disk like body 1, are provided with notches 3, which are adapted to receive the lugs A upon the closure of the head light. Provision is thereby made for properly accommodating the device to the lens or for uniformly associat ing the same therewith. Below the horizontal center, the body 1,

s provided with a relatively large opening 4, so that the'light as it is diffused by the purpose. The device is strong and'durable, compact and simple of construction and when not in use may be conveniently car ried upon the vehicle without occupying much space. V v

' In the modified form of the invention shown in Figs. 3 and 4 the body 1 is provided with a main perforated portion 2 having an additional element'of foraminous material indicated at 3 and disposed at I one side of the main body. The said member 3 is preferably corrugated vertically and it is found that in so doing and by fication is identical construction with the form described in the preferred embodiment.

What is claimed as new is A light dimmer comprising a disk pro- I vided with. a number of relatively small openings, said disk also having a relatively large opening, and a corrugated perforated sheet of material attached to the side of with the small openings.

In testimony whereof I aflixemy signature in presence of two witnesses.
