A. A. AUSTIN. LIGHTING FIXTURE. APPLICATION FILED MAYH. 1917.

Patented Jan. 15, 1918.

INVENTOFI ARTHUR A. AUSTIN, or PITTSBURGH, PENNsYLvANt A.

LIGHTING-FIXTURE.

Application filed May 11, 1917.

To all whom it may concern:

Be it known that I, ARTHUR A. AUs'rIN, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Lighting-Fixtures, of which the following is a specification.

My invention relates broadly to improve ments in lighting fixtures, and particularly to a spot shade designed for deflecting the rays from some specific area.

The primary object of my invention is to provide a spot shade of the type set forth which may be conveniently adjusted and manipulated to divert the rays of light of the lamp to which it is attached from any particular spot desired.

Other objects of my invention are to provide a device of the character described which is simple in its construction and arrangement, strong, durable and eflicient in its use, comparatively light in weight, attractive in appearance, and inexpensive to i'nanufacture.

To the accomplishment of these and such other objects as may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts herein specifically described, and illustrated in the accompanying drawing, wherein is shown an embodiment of the invention.

In the drawing, forming a portion of this specification and wherein like numerals of reference designate corresponding parts throughout the several views:

Figure 1 is a side view of an ordinary electric wall bracket and lamp provided with a spot shade in accordance with my invention.

Fig. 2 is a perspective view of my im proved spot shade and illustrating a rightangular adjustment of the shade in dotted lines.

Fig. 3 is a rear view of the device showing the shade carrying arm positioned at right angles with respect to the arm support.

Referring more in detail to the drawing, the spot shade, preferably constructed from sheet or strip metal, consists of the shade 1, the shade carrying arm 2 and the support 3.

The shade 1 is preferably rectangular in shape, and is provided with the corrugations 4 which extend from the corners of the said shade and converge at the central por- Specification of Letters Patent.

tion thereof, for the purpose of shaping the shade l to conform to the contour of the exterior of a round lamp globe, in connection with which the spot shade is primarily designed to be used. The shade 1. at its central point, is rigidly secured to the arm 2 by means of the rivet 6 or in any other suitable manner.

The arm 2 is connected to the support 3 by the hinge joint 6 in a manner so as to permit the quadrantal curvature of the arm 2 to overlap the support 3, of like curvatiu-e, thus allowing the adjustment of the shade 1 to any desired angle, and the folding up of the device for the purpose of storing same away when not in use, or for packing for shipment.

The support 3 consists of the members 7 and 8. One of the ends of each of the said members is connected in the hinge joint 6 to the arm 2. The other ends of the members 7 and 8 are shaped to form the clamp portion 9, which is formed by twisting each of the said ends a one quarter turn in opposite directions in relation to each other, and bending the said twisted ends to form the rectangular opening 10, as shown in Fig. 3 of the drawing.

The twisted ends, adjacent either side of the rectangular opening 10, are provided with the apertures 11 for the reception of the bolts 12, with which in conjunction of the nuts 13, the support 3 is attached to the lamp bracket or socket 14:, as shown in Fig. 1. The size or diameter of the bracket, pipe, socket, etc., to which it is desired to attach my improved spot shade, may vary considerably, being limited only to the length of the bolts 12. It will be obvious, from the construction of the clamp portion 9 together with the hinge joint 6, that the shade 1 may be positioned. at any angle with respect to the light.

The support members 7 and 8, and the arm 2 are reinforced and stiffened by the corrugations 15 and 16, respectively, which extend longitudinally throughout their whole extent, and permit the use of comparatively light material in their manufacture.

l/Vhile the use of my device is primarily intended for shading a specific spot or area, it will readily be seen that by frosting or polishing the inside surface of the shade 1 it may also conveniently serve as a reflector.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and While describing the principle of operation of the invention together with the device which is nowconsidered to be the best embodiment thereof, it is to be understood that the device shown is merely illustrative and that various changes in the form, proportion and the minor details of construction may be resorted to without departingfrom the principle or sacrificing any of the advantages of the invention as defined in the appended claims.

What I claim as new and desire to secure by Letters Patent is:

1. A spot shade, comprising a corrugated shade member, an arm quadrantal in curvature, attached to the said shade member, a support of like curvature consisting of two members hingedly connected to the said arm at one end and having the other ends thereof twisted a oneqi1arter turn and bent to form a clamp. portlon, substantially as described and for the purpose set forth.

7 2. In combination, a spot shade comprismg a rectangular shade member having cor- 7 said arm and support being further provided with corrugations extending longitudinally throughout their whole extent, substantially as described and for the purpose set forth. In testimony whereof I afliX my signature in the presence of two witnesses.

ARTHUR A. AUSTIN.
