ELECTRIC LAMP GUARD Filed Aug. 16, 1935 INVENTOR Robri' L. Gr t Attor y Patented Apr. 23, 1935 "UNITED STATES ELECTRIC LAMP GUARD Robert Lee Grant, Jr., Texarkana, Ark., assignor to Bessie Scott Grant, Texarkana, Ark.

Application August 16, 1933, Serial No. 685,470 In Canada April 12,1933

1 Claim.

This invention relates to an electric light bulb guard and more particularly to a combined guard and light shade for electric light bulbs which is an improvement over my prior Patent Number 1,893,409.

The primary object of the invention is the provision of a device of this character wherein on the mounting thereof upon an electric light socket having a light bulb therein the same will serve to protect the bulb and also will function as a shade for the light issued by the bulb, the device being adjustable to vary the shading of the light at the option of the user of such device.

Another object of the invention is the provision of a device of this character, wherein a shading shutter is movably supported in a novel manner Within the guard of a semi-bulbous reflector so that on adjustment of the shutter the light rays from a bulb of the electric type can be shut off or diminished accordingly to the requirement of the user of the light, the device in its entirety being of novel form.

A further object of the invention is the provision of a device of this character which constitutes an attachment or appliance for use with an electric light bulb socket so that an electric bulb when fitted therein or carried thereby will be protected or shielded and the light therefrom controlled or regulated for shading purposes, the parts of the device being assembled in a unique and novel manner.

A further object of the invention is the provision of a. device of this character which is simple in construction, thoroughly reliable and efiicient in its purposes, neat in appearance, readily and easily mounted upon and removed from an electric bulb socket, strong, durable, easy of adjustment and fully protective for a bulb and also inexpensive to manufacture.

With these and other objects in View, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawing, which disclosesthe preferred embodiment of the invention, and pointed out in the claim hereunto appended.

In the accompanying drawing:-

Figure 1 is a side elevation of an electric light bulb socket showing the device constructed in accordance with the invention applied thereto.

Figure 2 is a View similar to Figure 1 showing the device removed from the socket and the same in shifted position.

Figure 3 is a top plan view thereof.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates generally an electric light bulb socket of any standard construction and B the light bulb fitted therein, this bulb being of the usual type. Adapted to be mounted upon and carried by the socket A is the guard constituting the present invention and hereinafter fully described.

The guard comprises a semi-bulbous shaped reflector or body member 5 having an open side 6 through which issues the light from the bulb B. This reflector or body member 5 at its smaller end has a semi-circular band 1 bridging the open side 6 and this band with the companion portion of the member 5 constitutes a circular or annular track 8 for guide rollers 9 upon a semi-bulbous shaped shutter or closure 10 for the open side 6 of said reflector or member 5, the latter being rotatably pivoted at l l to the said reflector or member 5 while the rollers are'pivoted to the said shutter to project laterally onto the track and travel upon the same on adjustment of the shutter. Superposed or spaced with relation to the track 8 is an annular or circular retaining ring or band l2 which holds the rollers engaged with the track 8. Uniting the ring or band l2 with the track 8 is a series of straps Band II respectively, these being joined with said track 8 in any suitable manner. v

The straps M are extended upwardly beyond the ring or band 12 and are joined with a split ring-like clamp l6 which is adapted to embrace the socket A and is made firm or fast thereon by a nut carrying bolt or fastener I! so that the guard will be mounted upon the socket A in proper position to permit the inclosing of the bulb B and thus guard and protect the same.

In the use of the device when it is desired to shade the light issuing from the bulb B the shutter I I! is manually turned, thus reducing the size of the open side 6 and in this fashion regulating the light from the bulb as should be clearly obvious. When the shutter I0 is completely closed it will obliterate the light rays from the bulb B and thus shut off the light therefrom. v

The shutter I0 is fitted within the reflector or member 5 and its axis of movement is upon the pivot I i for the opening and closing action thereof, while the rollers 9 guide such shutter when traveling upon the track 8 as will be obvious.

What is claimed is:

An electric lamp guard comprising a pair of semi-bulbous shaped members, one swingingly movable into the other and the other constituting a stationary reflector, a band on the stationary reflector, the upper edge of the band constituting a track, a roller carried by the swinging member adapted to travel upon the track, a second band disposed vertically above said first mentioned band adapted to retain said roller on the track, straps connecting said bands together,

disposed in the path of said roller to limit the movement thereof, a pivot connecting said members remote from the bands and a clamp integrally formed with the upper ends of said straps adapted to embrace the electric lamp socket for securing the reflector thereon.
