GQW. BALDWIN. LAMP SUSPENDING DEVICE.

Patented Apr. 5, 1892.

I UNITED STATES PATENT OFFICE.

GEORGE WV. BALDWIN, OF MERIDEN, CONNECTICUT, ASSIGNOR TO THE EDWARD MILLER & COMPANY, OF SAME PLACE.

LAMP-SUSPEN DING DEVICE.

SPECIFICATION forming part of Letters Patent No. 472,468, dated April 5, 1892.

Application filed April 16, 1891.

To aZZ whom it may concern.-

Be it known that I, GEORGE W. BALDWIN, a citizen of the United States, residing at Meriden, Connecticut, have invented a new and useful Improvement in Lamp-Suspending Devices, of which the following is a specification.

My invention relates to that class of lampsuspending devices in which a shade or globe is supported by chains or cords from above. It is intended to simplify and cheapen the construction of such lamps.

In the accompanying drawings, Figure 1 represents in elevation what is known as a hall lamp embodying my device, partly broken away to show the interior mechanism. Fig. 2 is a vertical section through a lampshade provided with my device. Figs. 3 and 4 are top plan views of a portion of my device showing modifications.

The same letters refer to like parts in the several views. 1

A designates a lamp shade or globe; a, an internal stop or groove in the shade A; B, a band or ring; I), a fastening on the band B; b, a loop or hook on the band B; C, a chain or cord; D, a lamp-basket; E, a lamp; F, a canopy or ceiling-piece; f, a pulley in the canopy F.

The example of my invention, illustrated in Fig. 1 of the drawings, is of that class of lamps in which the weight of the lamp is balanced against that of the globe or shade. The chains 0, basket D, lamp E, canopy F, and pulleys f may be of any desired form and ornamentation. The shade or globe A is formed with a hollow exterior bead near its upper edge. Into theinterior annular groove 0., thus formed, issprung the band B, to which are secured the chains C. The chainsC (here shown as three in number) pass upward over the pulleys fin the canopy F and down to the basket D. It is obvious that the lowering of the lamp-basket D and lamp E will cause a corresponding elevation of the globe A, and that if the weight of the globe A is greater than that of the lamp and basket the position shown in the drawings will be one of stable equilibrium.

In Fig. 2 of the drawings 1 have shown the band B (here shown as circular in cross-sec- Serial No. 389,254. (No model.)

tion) in connection with a lamp-shade of the ordinary dome form. It is plain that the chains C may be attached to any convenient support, (not shown,) either stationary or movable. I have here shown in dotted lines that the stop a in the shade A need not be a groove, but may be only an internal bead or shoulder. I, however, prefer the grooved form first described.

The band B, as shown in Fig. 3, is secured at its ends by a tubular clip or fastening b. This clip I) may be slipped over one end of the band B before the band is placed in the groove in the shade. The clip I) may then be moved so as to cover both ends of the band B and secured in this position by crimping. As here shown, the band B is formed with a plurality of internally-projecting integral bends or loops 1), to which the chains 0 may be conveniently attached.

In Fig. at of the drawings the overlapping ends of the band B are secured together at b by a screw or bolt. Separate hooks b are here used instead of theintegral bends shown in Fig. 3.

It will be understood that by the termchain in the claims I include other like connection.

hat I claim as my invention, and desire to secure by Letters Patent of the United States, is as follows:

1. In combination, a lamp-shade, an internal annular shoulder in said shade, a band within said shade with its ends connected together, said band being of an exterior diameter corresponding substantially to the interior diameter of said shade immediately below said shoulder and a supporting-chain, substantially as described.

2. In combination, a lamp-shade, an internal annular groove in said shade, a band within said groove with its ends connected together, said band being of an exteriordiameter corresponding substantially to the interior diameter of said groove and greater than the interior diameter of said shade immediately above said groove and a supportingchain attached to said band, substantially as described.

3. In combination, a lamp-shade, an internal annular shoulder in said shade, a band a cord or corresponding substantially to the interior diameter of said groove, means for securing together the ends of said band after it; has been placed in said groove, and a supportingchain attached to said band, substantially as described.
