JAMES W. LYON, 0E BROOKLYN, NEW YORK'ASSIGNOR TO HIMSELF AND JOHN FELLOWS, 0E SAME PLACE.

Letters Patent No. 102,691, dated May 3, 1870.

IMPROVEMENT IN SHADE-HOLDERS FOR LA MPS.

The Schedule referred to in these Letters Patent and making part of the lame.

To all whom it may concern:

Be it known that I, JAMES W. Lxox, of the. city of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Shade-Holders for Lamps; and I do hereby declare that the following is a full and corsliding arms, which slide on the fixed arms, to adjustthe shade-holder to various sizes of shades. A shadeholder having these general features was patented by Hezekiah Knowles, July 9, 1867.

My invention consists iuthe employment of hard brass or iron wire, or other suitable hard wire, in the construction of the radial fixed arms and the sliding arms, and in attaching them to their central support, substantially as hereinafter shown and described;

Also, in forming the central support with a spring or springs to seize the gas-burnerby cutting a tongue or tongues in the sheet-metal central support.

Figure 1, of the drawings, represents a plan view of my improved shade holder, and

Figure 2, a side elevation thereof.

The other figures represent details of-constrnci-ion which will be hereinafter referred to.

Letter (0 represents the central support, which should be of thin sheet metal, and have a tongue, a, or more than one tongue, out in it,-aud bent inward, so as to form a spring, to seize the burner and hold the shade firmly.

The arms b of theshade-holder 1 construct of wire, bent in the form shown in Figure 3, the ends of the iron coming together and abutting, as at b, fig. 3.

This mode of constructing the fixed radial arms gives a loop, 0, at the end of each arm, to embrace the sliding or extensible part of the arms d, which 1 also make of wire, in the form shown in Figure 4, with a book, 0, to receive the shade, and a recess or shoulder, f, near the opposite end, to receive the slide clasp 9, made of thin sheet metal, of the form shown inFigures 5 and 6.

The sliding arms d are put through the loop at w the end of the fixed arms, and the slide-clasps y then applied, the part h of the clasps fitting the sliding arms, and the part 'i of the clasps being bent over, so as to embrace, the fixed arms, as shown in figs. 1

and 2.

W'hen the shade-holder is designed for an ordinary bat-wing or fish-tail gas-burner, -I make the fixed arms in one piece, bent as before state, in the form shown in fig. 3, and'attacll the arms by the central wire ring thus formed to t-heceut-ral support not thin sheet metal originally formed, asshown in Figure 8, and afterwards cutout so as to admit of closing .around the wire ring, as shown in figs. land 2.

Itwill be seen that the mode of construction above described makes a very strong, and at the sametimc, a cheap shade-hohler. It can be made much lighter and cheaper in nnportion to strength than the construction of the Knowles patent. A

I prefer .to use hard wire, but of course any wire that has stiifness enough to hold npthe shade may be used, hard wire being preferable because st-iiier in proportion to its weight. For making shade-holders for Argand burners or lamp-burners, the same, mode of construction may be followed, enlarging the central support, and making the sheet metal stifi'er, if necessary, by a. head or corrugation around it, or the arms may be made in loops separately, andriveted to a cast-metal central support, crooking the wire of the arms to form a rivet shoulder, as shown in Figure 7.

I claim as my invention and improvement in extensible shade-holders for gas-burners, lamps, &o.

1. The fixed looped radial arms, formed of one piece of wire, in combination with the sliding arms, also of wire, substantially as described.

2. The sheetmetal central support,,i,n combination with the looped radial arms, formed of wire, and the' sliding arms, also of wire, the whole put together substantially as described.

3. The combination with the sliding arms, the

looped radial arms, riveted to a central support, sub- I stantially as described.
