IMPROVEMEN'T IN SHADE-GLDERS. -4 o The 'Schedule referred to in these Letters Patent and making part of die rms.

To all whom 'it ma/y conce/rn:

Be it known that we, GEORGE H. DIMOND, GEORGE DOOLITTLE, and THOMAS B. DOOLITTLE, of Bridgeport, Fairfield county, in the State of Connecticut,

have invented a certain new and useful Improved- Shade-Holdem and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this application. f 4

Previous to our invention, it had been customary, in the use of porcelain and glass (or other analogous material) shades for lamps and gas-fixtures, to support the slage upon bearings at thelower edge or base of the s a e. l

There are obj ections to thus holding the shade, among which maybe mentioned, the obstruction by the supporting-arms of the light, the necessary weight tothe lamp or fixture` of 'sucharms, and their cost; and lighter shades, of paper, &c., have been made, with spring-devices at their tops, to claspto the chimney,

4 and thus avoid the objections to the base-supports and their necessary appendages; but, previous to our invention, no means had been devised lor suggested for connecting heavier shades, such as porcelain and glass, to the chimney ofthe lamp or argand gas-burner.

vQur invention has for its objects to provide a simple, economic, and efficient means (which maybe applied to all ordinary porcelain and glass shades now manufactured) of supporting such shades, from the top edge, on the chimney of a lamp or gas-,fixture and to this end,

Our invention consists in a metallic annular clasp, adapted to be sprung or clasped on to the top edge or anch of a shade, and provided with a suitable spring, or other means, for clamping it to the chimney of a lamp or gas-fixture, as will be hereinafter more fully explained.

To enable those skilled Yin the art to make and use our invention, we will proceed to describe it more particularly, referring by letters to the accompanying drawing, in which- Figure l is an elevation of a gas-fixture, chimney, and ordinary glass shade, with our invention attached.

Figure 2 is a top .view of the holder, (or device for supporting or holding the shade on the chimney.)

Figure 3 is a partial vertical section through the holder and shade, at x x, iig. 1.

In the diiierent gures the same parts are designated by the same letters of reference.

A illustrates a gas-fixture, provided with an argand burner, having the usual cylindrical chimney, B, on ,which is supported, by means ofour invention, a glass or.' porcelain shade, C, of the-usual shape.

e is an annillar metallic' collar, of the shape, in crosssectionseen at g. 3, which is adapted to fit loosely over the top edge, or tlanch,.ofthe shade C, as seen at to collapse or spring back to its normal condition and natural diameter.

When the device, (seen at fig. 2,) thus composed of the ring e and springs f, g, is placed or forced over the flanch, or top edge of a shade, C, the spring g. :fits into the concavity, near or under the flanch, or top lid of the shade, as shown at figs. l andy 3, and securely clasps itself to said shade, and the shade, with this device applied to it, may then applied to the chimney, B, of a lamp or gas-fixture, as seen at g. l, by distending or stretching over said chimney the ,spring-roll f.

It will be understood that the spring f will yield and adapt itself to any imperfection in the contour of the chimney, and to diametxical differences in different chimneys of nearly the same size.

And. the same characteristic feature, it will be observed, exists inthe means of attaching the device to the shade, so that the spring-clamp and holder, e f" g may be readily,- and with suicient security, attache v to different shades of nearly (though not exactly) the same size, and of imperfect shapes at the top edge.

It will be seen that, although the holder-device is attached with a suliicient degree of permanency, for all practical purposes, to the shade, the top of the latter is free to expand and contract within the coil-spring g, surrounding its topedge. Of course, by means of our improved spring-shade holder, the advantage is gained of the capacity to adjust the rigid shade to different heights on the chimney, as circumstances .reqmre.

The springs f and g might either or both be made in sections, in lieu of continuous, Without departing from the spirit of our invention, but we have shown the apparatus or holder made as We have successllly used it, and as we deem it bestto be made.

Instead of the angular (in cross-section) collar e, a

metallic band of different shape might be employed, or

the springs f and g might have interposed some other medium of connection, which would still permit each to perform its function, (one, that of clasping the top of the shade, and the other, that of clamping on to the' chimney,) as described, and, in lieu of using the spring j, as shown, some other means of Securing the collar e at ,the desired place` around the chimney might be devised.

We do not wish to be understood as limiting our claim of invention to the employment together of all the devices shown and described; but having fully described our invention, so that those skilled in the art or porcelain shade, of a holder, composed of a collar, e,

can make and use it, i provided with a spring, g, and a suitable means for What we claim as new, and desire to secure by Letclamping the collar around a chimney.
