UNITED STATES WILLIAM SGARLETT, or AURORA, ILLINOIS.

. IMPROVEMENT m SHADE-HOLDERS FOR LAMes.

Specification forming part of Letters Patent No. 173,186, dated February 8,1876; applicationfiled July 20, 1875.

To all whom it may concern Be it known that I, WILLIAM SCARLETT, of Aurora, Kane county lllinois, have invented certain new and useful Improvements relating to Shade-Holders for Lamps, of which The accompanying drawings form a part of this specification, and represent my improvement as applied to a kerosene-burner with a flat wick-tube. The shade may be of any ordinary or suitable construction.

Figure 1 is a vertical section, and Fig. 2 a plan View.

Similar letters of reference indicate like parts in both the figures.

A is the ordinary spun-brass collar, by which the burner is supported upon the lamp. On the extremity of an 'arm, A, therefrom is connected, by a hinged joint, 0, a perforated lid, B, having the ordinary dome formed in one therewith, or soldered or otherwise fixed thereon. Theouter edge of the lid Bis turned upward and finished as usual, two of the scallops, nearly opposite to the chimney-fastening screw D, being bent inward to engage with the rim of the chimney. All these parts, as also the ordinary spring-catch (not represented) for fastening down the lid, may be of the ordinary and long-approved construction. Another scallop, b, on the turned-up edge of the lidB,'is deflected outward, for a purpose which will appear hereafter. v

My shade-holder may be connected and disconnected at will. It is composed of a ring formed 'of two thicknesses of sheet metal, with their ends peculiarly joined, and of three wires, forming branches to support the shade, soldered in sockets formed by the rings. I have in my experimentsmade the inner part of the ring of tinned iron, and the outer part of brass, and will so describe them, though both parts may be formed of the same material, and of equal thickness, if preferred. The

-iron ring G is formed with one end plain, and

with'also one end "plain, and the other end formed hook-wise; and the hook it turned inward to engage with the iron hook. At three equidistant points in the circuit are formed socketsK by bending one or both of the rings. I prefer that the inner ring shall be continuous and smooth, or but very little deflected inward at the sockets. In other words, the whole or nearly all. the socket shall be formed by the bending of the outer ring H. The

sockets thus formed are of a size adapted to receive the turned-down inner ends of the branch wires or shade-supporting arms I,which are soldered firmly therein at their inner ends, and are formed, at or near their outer ends, with return bends I, to receive and firmly confine thelower edge bf the shade m.

The rings G and H may be soldered together continuously along their entire length, or they may be left unsoldered, except at the junctions with the arms*I,'or they maybe slightly soldered or sweated along their entire length.

I believe it practicable to unite them addilower edge of the inner ring, or by various other means; but I prefer the form represented, in which the rings are continuously soldered. Ahole, e, is made through both thicknesses G and H to receive the boss D for the screw D. Opposite to thisis the turned-out scallop b, before referred to. It engages in a hole, f, produced to receive it in' the inner ring H. This hole f is directly adjacent to one of the arms I, and the turned-out portion of the seallop b is of sufficient length to pass not only through the inner ring H, but also a little distance into the thickness of the vertical portion of the arm I, which is notched to receive it. To remove my shade-holder after taking off the shade, it is only necessary to apply the thumb and finger of each hand, taking hold with the right on one side of the hooked connectiong h, and with the left hand on the I other side of the said hooked connection, press one of the ends upward, while the other is held firmly in place. After displacing them to an extent equal to the width of the ring the hooks will be necessarily disengaged from each other. The'compound ring may then be slightly uncoiled or straighteneda form which it will usually assume naturally by its elasticityand it then readily disconnects itthe holder may be partially opened by disengaging the hooks g h, to allow the introduction or removal of the shade.

My shade-holder is held firmly and reliably in its place, and does not interfere with openin g and shutting the hinge, or putting on or ofl the chimney. It is connected or detached with little labor or skill. It requires no alteration of the sun hinged burner, except the simple one of bending outward the scallop b.

It may be applied to all lamps. The bottom of the collar A may be serrated to form a supply, or to increase the supply of air to the burner.

I propose usually to form two of the holes f, one each side of the root of the arm I which comes opposite to the hole e, and to turn out two scallops, b, to engage therein.

I claim as my invention-- 1. A duplex ring formed of two thicknesses of sheet metal, G H, with pockets K between, and provided with engaging books 9 h, in combination with arms I I, the whole being adapted to support a shade, and be supported upon a lamp-burner, as herein specified.

2. The combination of the shade-supporting arms, adapted to engage with the lower edge of the shade, a sheet-metal ring with hooks g h, for engaging and disengaging, ahole adapted to receive the boss or nut of the chimney-screw, and one or more holes on the opposite side, adapted to receive a turned-out scallop, b, on a lamp-burner, as herein specified.

In testimony whereof I have hereunto set my hand this 15th day of July, 1875, in the presence of two subscribing witnesses.

WILLIAM SGARLETT. Witnesses:

G. H. ADAMS, E. G. WHEATON.
