LAM P-SHADE.

SPECIFICATION forming part of Letters Patent No. 450,729, dated April 21, 1891.

Application filed December 31, 1890- Serial No. 376,422. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES F. MONROE, of Meriden, in the county of New Haven and State of Connecticut, have invented new and useful Improvements in Lamp-Ehades; and I do hereby declare the following to be a full, clear, and exact description of said invention, reference being had to the accoinpanyingdrawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in lamp-shades of the kind shown in my patent, No. 433,017, dated July 29, 1890, in which a sliding curtain is supported by a circular frame, which also supports a glass or other shade. In the construction shown in the drawings of said patent the edge of the vitreous shade rests directly on the upper ring of the curtain-frame, and therefore interferes with the sliding of the curtain and has a tendency to wear the curtain where it is passed over said ring. If the curtain is hung from the said frame-ring by means of small rings these latter, in sliding, make a disagreeable noise and leave marks around the edge of the shade, and of course the weight of the shade makes it necessary to use considerable force in sliding the curtain.

The object of my present invention is to produce a construction by which the abovementioned objections are avoided; and to this end my invention consists in the combination, with a shade, of a frame, a sliding curtain supported by the frame, and means for holding said shade separated from the frame.

In the accompanying drawings, Figure 1 is a side View of one form of my lampshade and holder. Fig. 2 is a perspective View of a modified form in which my invention maybe embodied, and Fig. 3 is a similar view of a double-ring curtain-frame and shade-support.

In Fig. 1 the tripod or shade-holder A is shown as having a collar to fit over the burner or neck of alamp and a plurality of upwardlyprojecting arms a, the upper ends a of which. extend slightly above the ringor curtain-frame B, which is preferably permanently secured to said arms in about the position shown. The edge of the shade will rest on the projections or lugs a, and will thus be held separated from the frame B in order that the rings 0 of the curtain C may slide freely on said frame. Of course the lugs a might project inwardly instead of upwardly, or they might be out-side instead of inside the ring.

In Fig. 2 the frame B is shown separate from the arms of the tripod or holder A, which are bent to directly engage the edge of the shade D. In this figure the frame B has inwardly-projecting lugs b to keep it separated from the shade on which it rests, the curtain being omitted from this figure.

In Fig. 3 I illustrate a frame B, consisting of two rings connected by a plurality of posts I), which are permanently secured to the inside of the rings, whereby the upper ends of the posts form the lugs on which the shade may rest and be held separated from the u pper ring on which the curtain slides. As indicated in said Fig. 3, the upper ends of the posts I) are flush with the upper surface of the upper ring, and, owing to the posts being inside of the ring, will properly support a shade which has an inclined shoulder; but in actual practice the posts should project slightly above the upper ring, in order that a shade having a substantiallyhorizontal shoulder may be properly spaced from the ring.

Having now described my invention, what I claim, and desire to secure by Letters Patent, 1s-

l. The combination, with a lamp-shade, of a frame, a sliding curtain carried by said frame, and means for holding the shade separated from the frame, substantially as described.

2. The combination, with a lamp-shade, of a circular frame, a sliding curtain carried by said frame, and supports for holding the shade and frame separated from each other, substantially as described.

3. The combination, with a circular frame, of a sliding curtain carried thereby, said frame having lugs projecting therefrom whereby a lampshade may be supported out of contact with the curtain, substantially as described.

In testimony whereof I aflix mysignature in presence of two subscribing witnesses.

CHARLES F. MONROE.
