To all whom it may concern:

Be it known that I, LnonR J. CAsToNsUAY, a citizen of the United States of America, residing in the city of Bridgeport, in the county of Fairfield, in the State of Connecticut, have invented certain new and useful Improvements in Shade-Holders, of which the following is a s ecification.

My invention re ates to shade holders for incandescent electric lamps, more particu-. larly shade holders fada ted for use with tungsten or other high eflicienc metallic filament lamps. Such shade hol ers generally comprise a conical shell secured at its smaller end to the lamp socket and having suitable means by which the flanged neck of the shade may be secured in or detached from the larger open end of the shell. Y

The object of my invention is to construct such a shade holder that the shade may be readilyapplied or removed but will. be securely held while it is in place.

In the accompanying drawings Figure 1 is a side elevation of my improved shade holder; Fig. 2 is a sectional plan on the line 2-2, Fig. 1; Fig. 3 is a like sectional view but with the spring clips in position to engage and hold the shade.

In Fig. 1, the conical shell A of the shade holder is shown as secured at its upper smaller end to the lamp socket B between the two ribs 1) on the socket'shell. At its larger lower end, the shell is formed with a flanged mouth 0 of a' size to receive freely within it the flanged neck of the shade. Within this flanged mouth, I provide two spring clips D, D, each secured at one end, as by riveting, to the shell, and havin itsmain body part lying within the mout of the shell, while the free end of each spring clip is bent and passes more or less radially outward through a horizontal slot e in the shell. Adjacent to the point where each spring clip D is secured to the shell, the wire shade.

innerends, such that the clips when pressed toward each other may be engaged in these catches, and held thereby in the positions shown in Fig. 3. When not so held, the spring clips are pressed by their elasticit outward a ainst the inner walls of the shel and then t e flanged neck of a shade may be introduced into the shell over the bends in. It then the projecting handles 03 be pressed together and the spring clips latched into the notches e, the clips will have engaged. and will securely hold the flanged neck of the shade S, until the clips are released again.

I claim as my invention A shade holder, comprising a shell adapted to be secured to a socket and having two slots with notches, near its month where it receives the flanged neck of the shade, in combination with two sprin clips each secured at one end to the shel and adapted when free to lie against the inner wall of the latter and having adjacent to itssecured end an i' ward bend a: and its free end projecting through one of said slots, said spring clips adapted when their free ends are pressed toward each other to be engaged in said notches and to engage and hold the In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
