ADJUSTABLE ELECTRIC-LIGHT SHADE AND REFLECTOR. l

Specication of Letters Patent. Patented Dec. 19, 1916.

Application led August 17, 1916. Serial No. 115,426.

I To all whom t may concern.'

Be itknown that I, RUSH F VAss, a citi- Zen of the United States, resident of Vilmington, in the county of New Hanover and State of North Carolina, have made a cerytain new and useful Invention in Adjustable .Electric-Light Shades and Reflectors; and I jopposite part-spherical reflectors 10, each declare the following to be a full, clear, and

exact description of the same, 'such as willl enable others skilled in the art to which it appertains to make and use the invent1on,

reference ybeing had to the accompanyingv drawings, and to letters or figures of reference marked thereon, which form a partof this specification.

Figure 1 is a central vertical section of the reflector, as applied, upon line 1-1, Fig. 3.

Fig. 2 is a side view of the same, showing the relectorsreversed, Fig. 3 is a similar view Itaken from another side,.showing the reflectors adjusted to shade both sides of the lamp. Fig. 4 is a similar view showing the lreflectors adjusted to shade 'one side only.

Fig. 5 is a detail perspective view of the upper ring. Fig. 6 is a similarl view of the lower ring, showing the depending arms partly broken away. Fig. 7 is a section on the line 7 7, Fig. 4.

The invention has relation to electric light shades and reflectors, having for its object to provide an improved adjustable shade and'rellector, designed to shade the light upon any side and reflect the light in any direction desired, and it consists in the novel construction` and combinations of parts, as hereinafterset forth.

In the accompanying drawings, illustrating the invention, the numeral 2 designates an upper interiorly threaded annulus or ring, having anexterior milled or knurled portion 3, and4 is a. lower or split ring, having an exterior thread 5, engaged by the interior thread of the upper ring, the lower ring having an internal groove 6, designed to be snapped into engagement with the bead 7 of the electric light socket 8.

ACarried by the lower, or split ring are two diametrically opposite downwardly and outwardly extendingv arcuate arms 9, two

of the form of one-quarter of a hollow sphere, being at opposite portions of'their lower edges pivotally connected to the lower ends of said arms, by bolts 11 having thumb nuts y12.

Each reflector has at its top an arcuate recess 13, adapted to engage .neatly the outer surface of the split ring, to form normally1 a Ycomplete semi-spherical reflector, extending downwardly from the lamp socket in the usual way.

When it is desired to reverse the reflector so that it will cover and obscure the lower portion yof the lamp bulb, the reflector sections are moved through an arc ofninety degrees, upon the bolts 11 as centers, until their normally horizontal arcuate edges meet in a vertical plane, each .reflector having both arcuate edges4 thereof provided with strengthening ribs or flanges 14, 14', the flange of one reflector engaging a groove 142 of the flange of the other reflector, to form a perfect seam or light-tight jointl in all meetmg positions of the reflectors. And if it should be desired to have the reflector located entirely at one side or the other of each reflector is swung pivotally through an are of forty-five degrees, the thumb nut belng loosened before the adjustment is made and tightened to fix the adjustment in all cases.

In assembling the` parts, the upper collar or ring is first engaged with the electric light socket,'the lower split collar or ring being next engaged with said socket or snapped over the bead or ridge of the socket, the upper collar being then engaged with the lower collar to prevent the lower collar from becoming disengaged with said bead. The reflectors are next adjusted to position and the thumb nuts tightened to fiX the adjustment.

The various parts may be made of brass or other suitable material, pressed or otherwise formed, and the threads of the collars may be formed in the same way as standard socket threads. The arms 9 may be of any suitable size or length, and are usually provided with slots llf engaged by the bolts .11 to permit a bodily ladjustment vertically of the reflectors.

The attachment is of simple nature and capable of. being attached to the standard light sockets by an unskilled person. The lower ring 4 isadjustable horizoneov , of the room.` a Iclaim:

1. In combination with an electric light socket having an exterior bead, an adjustable shade and reflector, comprising a carrying member provided with an interior groove land having detachable engagement with said bead and depending arms, and two quarterspherical hollow reflectors normally meet-4 ing in a vertical plane, pivoted at their lower inner corners to each other and to said arms l and each adjustable vertically.

2. In combination with an electric light socket having an exteriorbead, an adjustable shade and reflector, comprising a lower split ring having detachable engagement with said bead and depending arms, an up- -oted at their lower inner corners to each other and to said arms and each adjustable vertically.

3. Iny an adjustable electric light shade and reflector, a lampl socket, a carrying niemberI having horizontally adjustable engagement with said lam-p socket, and two normally meeting hollow part-spherical reectors. pivoted to said carrying member and to each other and each adjustable pivotally in a vertical direction, said reflectors
