NONGLABE ATTACHMENT FOR HEADLIGHT LAMPS.
Application led May 23, 1924. Serial No. 715,407.
The object of this invention is to provide an electric bulb filament lamp with a simple detachable non-glare shield of such structure that it may be attachedto the standard sizes of this type of lamp, as more fully hereinafter set forth.
In the' drawing- Fi l is a rear end View of a lamp bulb provided with one form of our attachment;
Fig. 2 is a side elevation of Fig..1;
Figs-3 and 4 are views similar to Figs. l and 2, respectively, showing our attachment adapted to a lamp bulb that is supported in ahorizontal position in a headlight.
In Figs. 1 and 2 we show a form ot' device which is adapted to support the non-glare shield 5 at'one side of the bulb. This is for, use in headlights in Vwhich the bulb is supported in a vertical position, to thereby present one Vside of the lamp to the lfront open side of the headlight. The supportfoi.
thelshield is so constructed that it will sup-.-
port the shield at the front side of the lamp, in such position that it will be practical y impossiblefor a person standing in front of the headlight to get a direct View of the lilament. In this way, an observer in front of the headlight will be prevented from being blinded from the rays of light from the filament. The shield is translucent so that very little of the illuminating power of the lz'mp is lost.
The shield 5 may be made of any translu` cent material. Tinted or etched glass will answer, and even a fine wire mesh screen,
known as a mosaic screen, will serve our purpose. In the illustrated example of our invention, the screen is shown as circular Vand is fastened to a circular wire ring 6.. the ends of the ring being turned laterally to form arms 6 which are twisted together at 7 to thereby enable the two free ends of `the wire to be formed into a pair of curved clamping arms 8 which are shaped to hug the cylindrical base or neckv of the lamp.
The arms 8 are springy so as to be snapped on or oft' the neck of the lamp, thereby ren-' dering't-he device attachable to and detachable from the standard headlight lamp.
In Figs.' 3 and 4, the shield-support is constructed so as tosupport the shield in front of the tip of the bulb. This form of device is adapted for use with those lamps which are supportedin a. horizontal position in the headlight, with their tips point. ing forwardly. Toadapt the wire support for this type of lamp, it will be simply necessary to use longer wire arms 6 and curve them so that the clamp-arms ,8 will hug. the neck of the lamp at the junction thereof with the bulb.
that we claim as new is:
A non-glare attachment for electric lamp? bulbs embodying'a non-glare glass disk and -a wire'support for detachably attaching the same tothe lamp coiixsisting of a single Wire bent midway its length to form an encircling frame for'permanently clamping thc rim of said non-glare shield, the two parts of the wire extendedl away rom'said disk and then brought together andtwisted upon each other at a point distant lfrom `their extremities, said two free extremities being spread apart to form a two-arm -springzlasp for engagement with the neck of the amp. Y
In `testimony whereof we hereunto alix our signatures this 22nd day of May 1924.
