Application August 19, 1936, Serial No. 96,832

4 Claims.

An object of the invention is to provide an improved securing means.

Another object is to provide an improved securing means which will be simple in construction and application.

Another object is to provide an improved securing means which will be economical to manufacture.

Another object is to provide an improved securing means which will effectively hold parts together.

Another object is to provide an improved means of deflecting light which will be simple and effective.

Another object is to provide an improved means of deflecting light which may be readily adjusted.

Other objects will hereinafter appear.

The invention will be better understood from the description of one practical embodiment thereof, illustrated in the accompanying drawing, in which;

Figure 1 is a perspective view of a lamp shade or reflector having a light deflecting extension secured to it, the extension and securing means constituting one embodiment of the invention; and

Figure 2 is a fragmentary sectional view of the parts illustrated in Figure 1, showing the manner in which the deflector is applied and secured.

A more or less conventional lamp socket is illustrated at I, it being provided with an incan descent electric light bulb 2. Carried by the socket is a shade consisting of a neck 3 and an outwardly flaring portion 4 which terminates in a peripheral annular bead 5. This reflector may be of any desired material, as glass, porcelain, metal, or metal coated with enamel, such as the shades or reflectors in more or less common use at the present time.

Ordinarily, such reflectors are of insufilcient depth to completely conceal the incandescent bulb, but while they reflect considerable light emanating from the upper portion of the bulb, they permit rays to emanate directly from the filament thereof past the shade, illuminating a zone substantially greater than a hemisphere.

Thus, when a shade is arranged with its margin in horizontal position at eye level, or even somewhat below this level, rays passing directly from the bulb reach the eye. When the shade and bulb are arranged over an article to be illuminated, light coming from the bulb directly to the eye of the observer subjects his eye to a considerable strain.

If rays reach his eye only after being reflected by the object which it is desired shall be illuminated, not only is this strain reduced, but the object can more clearly be perceived.

To obtain this advantage, I have provided a screen or deflector which may be applied to a portion of the periphery of the shade and which will prevent any direct rays from the incandescent light source within the shade reaching the eye of an observer.

This screen or shield is shown as an arcuate cylindrical plate 6, having a beaded upper edge 1 capable of overlying the peripheral bead 5 of the shade.

Through the plate are provided a series of perforations 8 adjacent this upper edge, and for each perforation is supplied a clip conveniently made of resilient material such as metal wire, having an offset upper end as indicated at 9 terminating in a hook Ill, an intermediate substantially straight shank H, and a lower end or detent l2.

The clip is inserted in the position indicated in dotted lines in Figure 2, and then is swung downwardly into the position shown in full lines in this figure, where its lower end I2 is snapped under the lower edge of the deflector. Due to the resiliency of the wire, it maintains pressure upon the lower edge of the plate and also upon the inside of the bead of the shade, effectively se curing the deflector plate thereto.

Obviously, several of the clips may be used on each deflector plate, two or three generally being sufiicient to securely hold the plate in place.

While I have described the illustrated embodiment of my invention in some particularity, obviously others will readily occur to those skilled in this art, and I do not therefore limit myself to the precise details shown and described, but claim as my invention all embodiments, variations and modifications coming within the scope of the appended claims.

I claim:

1. A light shield comprising an arcuate metal plate adapted to be secured to the margin of a shade, the plate having a curved channel-shaped edge shaped to embrace the edge of said shade, and means engaging opposite surfaces of the edge of said shade holding said edges in contact.

2. A light shield comprising an arcuate metal plate adapted to be secured to the margin of a shade, the plate having a curved channel-shaped edge shaped to embrace the edge of said shade,

and a plurality of clips detachably engaging said plate and arranged to contact the opposite side of the marginal portion of said shade in alignment with said edge.

3. An arcuate cylindrical plate having a channel-shaped recessed edge, a plurality of holes through said plate adjacent said edge, a clip extending through each of said holes, each clip comprising a resilient member having a hookshaped end projecting into the open side of said channel-shaped edge, a straight intermediate part lying closely adjacent the surface of said plate, and a detent engaging the edge of said plate remote from said first mentioned edge.

4. In combination, a lamp shape having a channel-shaped edge, a shield having a channelshaped edge overlying the edge of the shade, the shield being provided with a plurality of apertures closely adjacent said edge, a clip extending through each aperture and having a hook-shaped end bearing upon the interior of the channelshaped edge of the shade, the clip extending downwardly below the remote edge of the plate,

and resiliently engaging this last mentioned edge 10 of the plate.

RAY BROWN.
