SHADE-SUPPORT.

SPECIFICATION forming part Of Letters Patent NO. 620,685, dated March 7, 1899.

Application filed June 9, 1898. Serial No. 682,998- (No model.)

To all whom it may concern.-

Be it known that I, THOMAS IVALSH, a citizen of the United States, residing at New York city, borough of Manhattan, New York, have invented certain new and useful Improvements in Shade-Supports, of which the following is a full, clear, and exact description.

My invention relates to shade-supports; and my object is to provide a cheap, easilyassembled, and yet effective-fastening.

In the preferred embodiment of my invention shown in the accompanying drawings, Figure 1 is a vertical sectional view through my improved shade-holder on the line X X of Fig. 2 and through a shade as applied to the socket of an incandescentrelectric-light bulb. Fig. 2 is a plan view from underneath of the holder detached, shown in its locked position, and in its unlocked position in dotted lines.

In this embodiment of my invention the holder is supported by a split spring socketholder E, stamped out from the metal in the center of the ring 0 and bent up perpendicular to said base-ring O, as shown in Fig. 1. D is a bridge to connect one part of the socketholder with the base-ring. F F are bridges preferably formed integral with said ring and sides of said socket-holder, and through these bridges is passed a screw G, preferably having a collar G thereon to abut against one of these bridges and which screw engages a screw-threaded hole in the other bridge. The metal of which this socket-holder is made is thin and preferably resilient, and the screw is used to draw together or force apart the bridges, and therefore decrease or increase the size of the socket-holder E. This form of my shade-holder consists of a ring A, preferably formed of a base-ring (J and the rim B perpendicular thereto. passed up inside of this rim, and the locking members are slipped under the flange to hold it. The locking means in this embodiment consists, preferably, of one piece of wire bent roughly into a circle and having at intervals therein a double bend L L to form a locking means. H H are guides for this clamp, preferably formed, as shown, of lips from the rim B, spun over it and inclosing the ends of the clamps at the sides of said bend. A handle M may also be provided. When the handle is moved upward in Fig. 2 into the The flanged shade is position shown in dotted lines, the elbows L are moved outward to allow the shade to be inserted, and at the same time the elbows L move out-ward through slots H in the rim and project outside of the same, as shown in dotted lines. The shade is then inserted and the clamp moved back, when the elbows L willbe projected inward and pass under the flange to lock the shade. In this way it will be observed I have provided a cheap and easily-assembled holder which may be quickly operated and which provides a secure locking means. If a shade greater in its internal diameter than the external diameter of the ring A and having an inwardly instead of an outwardly projecting flange were placed over said ring, it would be locked and supported by the elbows L and the handle M, which when provided forms one of the external elbows, when the clamp is in the position shown in dotted lines; but as this would not involve any material change in the construction shown I have not illustrated the same in the drawings. It will be obvious that very many variations may be made in these constructions without departing from the spirit of my invention.

What I claim is 1. In combination a'ring, a curved flexible clamp having therein a double bend, and a guide for each end of said clamp at the sides of the bend, in which guides said clamp is 1011- gitudinally movable, the elbows of said double bend beingat different distances from the center of the ring.

2. In combination a support, a ring, a

curved flexible clamp having therein a double bend, a guide on said ring on either side of said bend and adapted to hold the ends of said clamp at the sides of said bend, said ring having a slot between said guides for the passage of said bend.

8. In combination, a support, a ring, a curved flexible clamp having therein a double bend, a guide on said ring on either side of said bend and adapted to hold the ends of said clamp at the sides of said bend, the elbows of said double bend being at different distances from the center of said ring.
