SHADE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 285,964, dated October 2, 1883.

Application filed March 7, 1881. (No model.)

51'0 all whom it may concern:

Be it known that I, J AMES BRANNEN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Shade-Supporters, of which the following is a specification, reference being had to the accompanying drawings, wherein Figure l is a longitudinal section of a shade holder bracket with my improvements applied thereto. Fig. 2 is a broken elevation of the shade in the bracket, the latter being partly in section. Fig. 8 is a detail perspective, and Fig. i is a horizontal section of a modification of my improvements.

The object of my invention is to provide an improved shade-holder for lamps or gaschandeliers or railroad passenger-coaches; and the novelty consists in the combination, with the collar which receives the neck of the shade, of a clasp or clamp having a suitable stem or knob for withdrawing the clamp or clasp from impingement against the neck of the shade, a spring to effect and control said pressure or impingement, and a supplementary clamp to accommodate shades with small necks.

Referring to the accompanying drawings, A d signates a metallic collar, which is adapted to receive the neck of the suspended shade, and which is usually a part of the gas-fixture. B is a box riveted or otherwise suitably attached to the outside of the collar, and having a central opening for the passage of an annular stem, 0, provided at its outer end with a knob, c, and attached at its inner end to the curved plate (I, constituting the clamp or clasp. The box B is formed with a cavity to receive a spiral spring, I), which encircles the stem 0. Said spring bears at-its inner end against a collar, b, on the stem, and is retained in place by a screw-cap, W, on the outer end of the box.

'The neck of the shade is made with two beads about a half-inch or so apart, and the claspingplate (Z is so shaped as to fit between the beads,

back, so as to firmly clasp the neck of the shade, which it will do without injury or danger of injury to the glass. No more force than is inherent in the spring itself is exerted in clamping the neck of the shade, and while this is sutficient for the purpose of firmly holding the shade in place it is not enough to fracture or inj uriously compress it. As the shades for which this holder is intended are of standard size, the holder, with a single clamping-plate, as described, will be generally found sufficient. To provide, however, for exceptional cases, as where shades of a smaller diameter of neck than the standard are used, I suggest the employment of an additional fixture, as shown in Fig. 4. This consists of asupplementary clasping-plate, 0, having an angular stem, 6, which slides in a box, F, and has swiveled to its outer end an adjusting screw, G, working in the threaded cap 9; By turning said screw the plate 6 may be adjusted to fit any diameter of shade, so that when the spring-clasp is brought into requisition the shade will be securely held between and by the two.

What I claim is as follows:

The combination, with collar A and sliding spring clamp or clasp, of a supplementary adjustable clamp or clasp, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set March, 1881.

JAMES BRANNEN.
