2 Claims. (Cl. 240-138) This invention relates to lamp shades and more particularly to providing improved means for securing various types of lamp shades to electric light bulbs.

Lamp shade holders, that is, lamp shade holders comprising a clamping device consisting of two or more open or loop-shaped clamping members which are adapted to be received by an enlarged end of an electric light bulb in such a way as to support the shade in a desired manner, have been constructed in a great number of forms. All of the forms of construction, however, have one or more limiting factors which either contributes to an increased cost of the shade assembly or to its complexity. Our invention overcomes most, if not all, of these limiting factors and provides amore useable and saleable form of lamp shade holder.

Briefly, our improved lamp shade holder is so constructed as to readily receive individual clamping members in slots provided in the holder. The complementary clamping members are so constructed and arranged to permit the members to be spread apart to resiliently clamp a light bulb. For purposes of packaging, shipping and storing, the clamping members can be easily disengaged from the holder and compactly nestled together. We have also provided a novel construction for securing the lamp shade holders to the lamp shade.

A general object of our invention, therefore, is to provide an exceedingly simple, efficient and economically constructed lamp shade holder and assembly.

Another object of our invention is the provision of an improved lamp shade holder which is so constructed and arranged as to be readily assembled and disassembled for purposes of packaging, shipping and storing.

Yet another object of our invention is to provide a lamp shade holder which is adaptable to support a great variety of lamp shades with various sizes of openings and centers.

These and other objects and advantages of this invention will hereinafter appear and for purposes of illustration, but not or" limitation, preferred embodiments of the invention are shown in the accompanying drawings in which:

Figure l is a perspective view showing our new lamp shade holder;

Figure 2 is a side elevational view, partially in section, of our new lamp shade holder;

Figure 3 is a top plan view of our new lamp shade holder;

Figure 4 is a perspective view showing the parts compn'sing our new lamp shade holder and assembly;

Figure 5 is a sectional view taken on line 55 of Figure 3; and

Figure 6 is a modified form of lamp shade holder applicable to our invention.

Referring to the drawings, and more particularly to Figures 1 and 2, there is illustrated a lamp shade S which may be of any suitable character and configuration. In the example shown, shade S is frusto-conical in shape and, at the smaller end thereof carries an attaching or ice supporting member or holder H. The holder H is disposed substantially centrally of the smaller end of the shade S and comprises a ring 10, generally made of a light gauge metal. Said ring 10 has a plurality of outwardly disposed ears 12 generally of circular shape, the purpose of which will be pointed out hereinafter.

The ring 1.0 can be of any desired form, such as a flat piece of metal or with a downwardly extending flange 14 as shown in the drawings. A pair of complementary slots 16 and 18 are provided on the interior side of the ring 19 and extend substantially midway into the ring 10. The pair of slots 16 and 18 are disposed opposite each other so that they are in approximately the same plane. Preferably the slots 16 and 18 are disposed at an angle inclined towards the center of the ring 10.

The slots 16 and 18 are adapted to receive resilient clamping members 20 and 22, which clamping members are preferably made of a relatively light spring wire and are of open or loop form, so that they may readily adapt themselves to the larger ends of electric light bulbs. The clamping members 26 and 22 are of identical construction and at both ends of the holders are formed loops 20a and 2211 which are bent back upon themselves and in the same plane as the clamping members 20 and 22. The loops Zita and 22a of the clamping members 20 and 22 terminate in short lugs 20b and 22b which are bent at substantially right angles to the clamping members 20 and 22.

When the clamping members 2:? and 22 are formed, we prefer that the open ends be somewhat larger than the diameter of the ring 10 in order that the ends thereof will be urged outwardly so that they will be firmly held by the ring it) when they are in engagement With the slots 16 and 18 thereof.

The clamping members 20 and 22 are inserted into the ring 11) by compressing the holders, placing the compressed ends of the holders within the inner portion of the ring 10 until each of the loops of the respective holders is engaged in the slots 16 and 13 of the ring 10 as shown in Figures 2 and 3 of the drawings. Because the clamping members are made of relatively light spring wire and the open ends of the holders are larger than the diameter of the ring 16, the clamping members will be resiliently held within the slots 16 and 18 of the ring it To disengage the holders 2% and 22 from the ring 10, the procedure is reversed.

Thus it is to be seen that this unique and relatively simple construction and design of the clmping members 20 and 22 permits them to be readily assembled to or disengaged from the ring 16 of the holder H by simply compressing the members 24) and 2?. until the loops 20a and 22a are engaged with or disengaged from the slots of the ring it). This is of great importance since ready assembly and disassembly of the clamping holders 2%) and 22 from the holder H greatly decreases the total cost of the complete lamp shade holder. This results in a saving of space when the complete lamp shade assembly is packaged for shipping or storage which, of course, means a less expensive unit.

The ring 1t) of the holder H is secured to the shade S through the ears 12 which are crimped about short rods 24, the opposite ends of which receive brackets 26 which are also crimped about the rods 24. The brackets 26 comprise ears 26a which are integral with a flat plate 26b which is bent at its terminal end to form a downwardly turned lip 260. The lip 260 of the bracket 26 envelops a portion of the edge of the shade S, which may or may not be reinforced depending upon the type of material out of which the shade S is made. After the lip 26c of the bracket 26 is secured to the shade S, the edge of the shade S is preferably reinforced with a small metal band 28 which can be crimped about the top of the shade which 3 also acts :to secure the lip 26's of the bracket '26 to 'the shade S. As can readily be seen, the manufacture of the rods 24, brackets 26 and band 28 is inexpensive and permits an economical assembly of these parts into a complete Ila-nip shade 1holder assembly We have shown in :Figure 2 and :Figure 5 the position our clamping members .20 and 22 assume when they :are in engagement with anelectricli-gh't bulb B. The terminal ends of the lugsltlb and 22b of theholders, when they are spread apart to-accommodate to the size of the electric bulb, are forced and bear against the top of the ring which, 'ofcourse, retards the movement that the clamping members can make resulting in the formation of a resilient clamp to hold the lampshade to the electric bulb.

One of the many modified forms of lamp shade holder to which our invention is adaptable is :shown in Figure '6. The rnodified form shown in that figure is vfor use with a bridge type tlamp wherein an ornamental top is desired. This form of lampshade holder requires the ring 10 be bridged by a flange 30 having an opening centrally disposed to receive an ornamental top (not shown). The

construction and principle of operation of this modified form of lamp shade holder is in all other respects similar to the lamp shade holder heretofore described.

Thus we have shown a new type of lamp shade holder and assembly which is comprised of relatively few'parts which can be easily manufactured and economically assembled. Each of the .parts, in their combination, permits a new-and different cooperation which makes possible a very inexpensive lamp shade assembly and without reducing the quality 'of the item.

While we have shown and described specific embodiments of our invention, it will, of course, be understood that we do not wish to be limited thereto and that by the appended claims We intend to cover all modifications and alternative constructions falling within the true spirit and scope of'the claims.

We claim:

1. A lamp shade assembly for attachment -to a light bulb comprising, in combination, acentral annular bridge defining an inner rim, attachment means extending from the bridge for attachment to the lamp shade, paired opposing slots in the inner rim of the annular bridge, a pair of separate resilient loop shaped light bulb clamping members having legs at the open ends of the loops, lugs at the end of the loop legs, the lugs extending laterally from the plane of the loop, the loop legs and slots in the annular bridge being proportioned for a mating fit so that the loop legs can be snapped into place in the bridge slots and thereafter the light bulb loops snapped over a light bulb resiliently-locking the :loop lugs and legs within the bridge slots.

2. In a lamp shade assembly having a central bridge with upper and lower faces, removable 'bu'lb olamping means comprising, :in combination, a pair of separate bulb clamping loops, each loop being characterized by its formation from a resilient material and having inwardly turned lugs at its open ends, and two pairs of opposed slots in the bridge proportioned to .receive the loop ends and defining a lug supporting area, the loops enacting with theslots to removably secure the loops in the bridge, the loops extending .from the lower face of the bridge, and

the :lugs cooperating with the upper face of the bridge to anchor the loop open ends thereby enabling the bulb, when inserted between the loops, to impart a locking action to the lugs and loop ends at the slots and lug supporting area.
