To all whom it may concern.-

Be it known that I, MORRIS D. GREENGARD, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Shade- Holders, of which the following is a full,clear, and exact description, reference being had to the accompanying drawings; forming a part hereof.

My invention has relation to improvements in shade-holders for electric incandescent lamps; and it consists in the novel arrangement and combination of parts more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is atop plan view of my improved shade-holder. Fig. 2 is a vertical section on the line mxof Fig. 1. Fig. 3 is a horizontal section on line y y of Fig. 2. Fig. 4 is a perspective view of one ofthe shaderetaining arms. Fig. 5 is an elevation of a portion of the outside or periphery of the shade-ring, showing the openings for mounting the shade-retaining arms. Fig. 6 isa similar view of a modified form of shade-ring, and Fig. 7 is a perspective view of the forked end of one of the levers by which the clampingband of the holder'is controlled.

The object of my invention is to construct a shade-holder for electric lamps which can .be secured to the socket of such lamps and to which the shade can be attached without the use of screws, one in which the mechanism for securing the holder to the lamp-socket is materially simplified and at the same time rendered thoroughly effective, one in which the devices for retaining theshade to the holder are materially reduced in weight, one in which the frame is preferably made of a single piece of metal, and one presenting fur ther and other advantages more apparent from a detailed description of the device; which is as follows:

Referring to the drawings, 1 represents the shade-ring or the ring to which the shade is secured, said ring having formed (preferably) integrally therewith a series of pairs of webs 2, inclined in'wardlyto the general plane of the circle of the shade-ring, one member of each pair of webs being connected at its up per or free yielding end with the nearest member of the next adjacent pair by a clampingband section 3, the several sections forming, collectively, a clamping-band by which the socket of the lamp can be seized or embraced. The shade-ring,'the clamping-band, and the connecting-webs thus form a frame cut or stamped preferably from a single piece of metal.

The members of each pair of webs are provided at a point adjacent to or nearest the free or yielding end thereof with oppositelyextendinglugs 4, from the free ends of which are deflected outwardly and in a plane substantially perpendicular to the plane of the shade-ring the ears 5, each pair of cars being adapted to receive the opposite extensions of the pivotal axis of a controlling or operating lever 6,swinging in a plane disposed in the line of the radius of the circle of the shade-ring and perpendicularto theplanethereof. Theshort arm of said controlling-lever is forked, the members of the said fork being rearwardly or inwardly deflected and normally embracing the outer edges of the webs at a point between the axis of the lever and the clampingband, the embracing-fork members having inclined or outwardly-diverging contacting sides 7, whereby upon the rocking of the lever from the inside of the shade-frame outwardly,- or as indicated by the arrows in Fig. 2, the

- said embracing sides 7 will draw the yielding ends of the webs together, thus contracting the clamping-band (seedotted position of same in Fig. 1) and causing it to firmly embrace the socket of the lamp.

To retain the lever in any position to which it has been tilted and thus prevent the clamping-band from being released from the lampsocket, I provide each lever with an inwardlydirected extension 6, serrated along its outer face, the serrated face being adapted to ride along the shade-ring at the base of the webs, it being rememberedfthat said extension is springy or resilient, so that it always remains in engagement with theshade-ring. To more effectively engage the serrations,- I form. a tongue 8 on the ring. Other equivalent means, however, for retaining the operatinglever in position may be resorted to without departing from the spirit of my invention. Of course upon swinging the operating-lever inwardly the forked end of the short arm thereof will permit the webs to expand to-their normally separated position, thus releasing the shade-holder from the lamp-socket. Itis, of course, within the spirit of my invention to deflect the extension 6 outwardly instead of inwardly, but the form here shown is preferable.

Formed along the shade-ring are a series of pairs of openings 9 10, through the former of which is adapted to be inserted (lengthwise of the opening) the pivotal head 11 of a shade-retaining arm 12, the head 11, when the arm is in place, overlapping the sides of the opening 9 (see Fig. on the outer periphery of the shade-ring, the arm 12 being thus directed toward the inside of the frame. The arm 12 has an outwardly-bent springy or resilient extension 12, serrated along the ontersurface, said extension being inserted from the inside of the shade-ring through the opening 10, permitting the serrations of the extension to ride over the tongue 13, formed along the adjacent side of the said opening 10. The frictional engagement between the serrations of the extension and the tongue 13 is suflicient to retain the arm 12 in any position to which it may be swung, the elbow 14, formed between the arm proper and its extension, serving to engage the shade-rim l5 and hold the shade within the holder. The dotted position in Fig. 3 shows the arm swung outwardly, or in a position either to release the shade or permit its insertion into the shade-ring. The arms 12 are preferably mounted, as here shown, to operate or swing in a plane parallel substantially to the plane of the circle of the shadering.

In case of a narrow shade-ring, where the punching of the metal for the formation of the openings 9 10 might weaken the ring, I may substitute the construction of ring shown in Fig. 6, where the base of the U-shaped cleat 16 serves to retain the pivotal head ll of the arm 12, and where the basal tongue 17 of the cleat 18 serves as a bearing for the serrated extension 12 of the shade-retaining arm.

To one skilled in the art other equivalent details of constructions not here shown might suggest themselves.

It is obvious that the device might be used as a globe-holder for gas-burners.

Having described my invention, what I claim is 1. In a shade-holder, a suitable shade-ring, a series of pairs of webs carried thereby, a series of clamping-band sections connecting respectively the one member of one pair of webs with the nearest member of the next succeeding pair, a controlling-lever in pivotal connection with each pair of webs and swinging normally in a plane at right angles to the plane of the circle of the shade-ring, said lever being adapted to vary the distance between the free or yielding ends of the webs, substantially as set forth.
