A ma-ill 3), W35 G. A. RICE ANTIGLARE HEADLIGHT ATTACHMENT Filed March 27, 1954 1 vehicles or the like.

Patented Apr. 30, 1935 isirsasriires was ori ice This invention relates to an attachment for headlights and more particularly to-a means in the form of an attachment to prevent glare from the headlight.

An object of this invention is to provide a shield which can be mounted on any conventional headlig bulb and which embodies a construction whereby the upwardly directed light rays from the reflector and the direct light rays from the source of light will be prevented from causing glare to oncoming vehicles.

Another object of this invention is to provide an anti-glare attachment of this type which can be constructed out of sheet metal which may be suitably formed as by stamping or the like so that it will snugly engage about a portion of the light bulb and which includes a means whereby the shield may be yieldably held on the bulb so that in the event the light bulb burns out, the attachment can be removed and placed on a new bulb.

The above and various other objects and advantages of this invention will'in part be described and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing wherein:--

Figure l is a detail side elevation of a light bulb having a device constructed according to the preferred embodiment of this invention, mounted thereon, the device being shown in longitudinal section. I

Figure 2 is a plan View of the device in blank form.

Figure 3 is a detail front elevation of the device.

Figure 4 is a sectional view taken on the line 6-4 of Figure 1.

Figure 5 is a sectional view taken on the line $45 of Figure l.

Figure 6 is a sectional view taken on the line Ei-t of Figure 3.

Referring to the drawing wherein like numerals of reference designate corresponding parts throughout the several views, the numeral It! designates generally a light bulb which is provided with a base I I adapted to engage in a conventional light bulb socket, as is used in motor This light bulb i0 is provided with opposed outstanding pins I3 for engagement in the usual bayonet slot provided in the socket.

In order to provide a means whereby the upwardly directed and horizontally directed light rays from the headlight associated with the light bulb It may be deflected so that they will not cause glare in the eyes of approaching drivers,

I have provided a shield structure comprising a concave plate l2 having a shank i l and a base structure i 5 which is adapted to be secured to the light bulb about the base I i by means of a spring or yieldable member 56.

The concave plate !2, in the present instance, is made outof metal of a suitable thickness such that itinay be readily made initially in template form and then or otherwise formed, as shown in the drawing. The upper end of the shield portion E2 is cut out, as at ll, so that the shield l2 will engage about a considerable portion of the light bulb it at the forward end thereof so as to prevent thehorizontal or direct light rays from being projected forwardly of the vehicle while at the same time permitting downwardly directed reflected light rays to freely pass forwardly of the vehicle.

The shank M has an elongated detent it! which acts as a bracing or strengthening means so that relatively light weight metal may be used which, on account of the strengthening member is, will snugly engage about the lower portion and the front portion of the light bulb iii. The base 55 comprises a pair of curved returned arms is which are connected together at their lower portions by means of a forwardly extending plate 26 secured at its forward portion as by solder 2i to the lower side of the rear ofthe shank M. The spring 56 engages the arms is at their uppermost portion, being looped or otherwise secured thereabout.

As will be shown from Figure 2, the shield or body portion i2 is constructed integral with the shank M.- and with the arms is as well as the plate or connecting member 29. The arms ii! are formed in blank form by punching out a circular opening in the rear portion of the plate, which rear portion is preferably wider than the width of the shank is so that these curved arms Y will form an open socket to receive the base portion ll of the light bulb. The attachment is placed on the lower side of the light bulb Hi and by reason of the spring it, the attachment can be suitably adjusted after the bulb it is engaged with the usual socket within the reflector of the head light. Preferably, the inner surface of the shield I2 is areflecting surface which may be formed by either polishing or plating the surface and the outer surface of the shield l2 may be opaque so that it will not reflect any light rays from the lower portion of the reflector.

As will be noted from Figures 3 and 6, the shield l 2 is provided on its front and lower surfaces with flat reflecting faces 22 so that the light rays reflected by the inner surface of the shield will be directed toward the upper portion of the reflector from which point the light rays will be projected in a forward and downward direction rather than upward direction. 'The shield herein disclosed will, therefore, not only prevent the upwardly directed rays from reaching the eyes of oncoming drivers but will concentrate the rays in the upper portion of the reflector, from which point they will be directed forwardly and downwardly, thereby increasing the lighting of the road ahead of the vehicle.

What is claimed is: I

1. A device as set forth, comprising a concav plate having an arcuate upper edge portion, a reduced shank carried by the rear of said plate, bracing means integral with said shank, a pair of V-shaped supporting arms having curved inner edge portions carried by said shank, said arms.

engaging about the base of the light bulb, bracing 4 means integral with said shank and each arm, and a spring secured to the converging portions of said arms and engaging about the base of the jshank, said arms engaging about the base of the light-bulb, a bracing means integral with said shank and each arm and extending forwardly of said arms, and a spring secured to the converging portions of said arms and engaging about the base of the light bulb.
