LAMP-SHADE HOLDER.

QPFCIFZCATIQN forming part of Letters Patent No. 339,708, dated April 13, 1886.

(No model.)

To all whom it may concern.-

Be it known that I, FREDRIOK A. STEARNS, a citizen of the United States, residing at )Valtham, in the county of Middlesex and Commonwealth of Massachusetts, have invented a new and useful Lamp-Shade Holder, of which the following is a specification.

My invention is an improvement in lampshade holders; and the object of my improvement is to provide a convenient and adjustable lamp-shade holder, so constructed thatit will support from the top of the chimney a shade of paper or other material without injury to the shade from the heat of the lamp or gas and without harm to the chimney from the holder. The insertion of the retainingpoints of my holder into the chimney secures the rapid distribution of heat to the great advantage of the chimney, and the method of supporting from the top secured by my holder. is less likely to injure the chimney by the application of a cold metal than when the holder rests upon the bulb or side of the chimney. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 represents one form, and Fig. 2 another form, of my invention.

The holder is thus constructed. A straight piece of any reasonably elastic wire about ten inches in length and of any desired thickness is bent at a point about three-quarters of an inch from the ends, so that the bent portion (a b in both figures) is nearly or quite parallel with the other portion, Fig. 1, or so that it-niakes with the other portion an angle of between forty and fifty degrees, Fig. 2. Then at a point on the longer and still un bent portion of the wire, distant about an inch and a quarter from the point of the former bending, the wire is bent in an opposite direction to the former bending, so as to form with the longer and still unbent portion of the wire an angle of between one hundred and fifty and one hundred and sixty degrees. Then at a point on the still unbent portion of the wire, distant about an inch from the point of the last-mentioned bending, the wire is again bent in an opposite direction to thelastmentioned bending, so as to form with the still unbent portion of the wire an angle of betioned bending, the wire is again bent in an I opposite direction to thelast-mentioned bending, so as to form with the still unbent portion of the wire an angle of between one hundred and fifty-five and one hundred and sixty-five degrees.

A ring of wire like that used for constructing the supports is now taken, and at points equidistant each from each on this ring three or more wires, bent as hereinbefore described and alike each to each, are attached to the ring, by solder or otherwise, at points on the wire designated as d, in Fig. 1, or halfway down the half-inch space, mentioned above, and the wires are attached at such an angle that the second arm (I) c in both figures) is vertical. The ring passes outside or inside the wires, which are so placed that the part corresponding to the starting-point (a in both figures) is toward the center of the ring. In place of the ring mentioned in the first part of this paragraph a band, as shown in Fig. 2, may be substituted. It varies from a third to two-thirds of an inch in width, and is of metal, similar to that used for the wire.

The alternative construction, as shown in Fig. 2 and hereinbel'ore referred to, is used in making wires for shade-holders for flan ing-top or bell-niouth chimneys. It is of course necessary that the wires taken to form with the ring or band a shade-holder should be alike, not some bent for the usual and some for the belln1onth chimneys. A second ring of the same wire may be attached in a similar manner at a point about ouehalf an inch from the lower end of the wires. This second ring is not essential, but is preferred for some forms of shade and maybe used. The distance above given may vary slightly, according to the size of the chimney on which the holder is to be used. Of course, the diameter of the ring varies according to the size of the holder to be made.

\Vhen completed, the shade-holder is used by inserting the upper ends (a a u in both figures) into the top of the chimucyand pushing i v i W i I v K i V a,, w ,4

the holder down until the top of the chimney c, to be inserted in the chimney, and other is up to the point designated asb b b in both bends, c, d, and 6, so as to properly separate the figures. shade from the chimney, with the band or ring I am aware that holdershavebeen made and d d d, to support lamp-shades from the top of I 5 5 used to support the shade by a series of radial the chimney, all substantially as described,and

braces upon the bulb or side of the chimney, for the purposes set forth. and I do not claim any such holder; but

\Vhat I do claim, and desire to secure by FREDRIOK STEARNS Letters Patent, is- Witnesses: 1c The combination, in the form of a truss, of FREDERIo HAYES,
