HTTOR/VEK Patented May 13, 1952 2,596,626 LAMP SHADE AND MOUNTING THEREFOR I William E. Vogel, Los Angeles, Calif., assignor to Lighting Specialties, Inc., Los Angeles, Calif., a corporation of California Application September 18, 1948, Serial No. 49,909

3 Claims. 1

This invention relates to a lamp shade and mounting therefor. Popularity of the little standing lamps, used mainly on dressing tables has created a heavy demand for sturdy, attractive and relatively inexpensive shades for use therewith.

It is an object of this invention to provide a lamp shade and mounting therefor which is attractive and sturdy but which can be inexpensively produced.

Shades of the type to which this invention relates must be mounted directly on the electric lamp bulb. The most general means used for this purpose has been a pair of circular wire loops engaging opposite sides of the bulb. These loops have been employed in many different ways either as an integral part of the wire frame of the shade or as an adapter connecting with screw collars on the shade provided primarily for screwing onto a socket.

Heretofore, when shanks formed on circular globe engaging loops were held together by a ring encircling the necks of the loops, the opposite ends of these shanks were welded to a wire ring embodied with the shade in order to anchor these shanks against the torque imposed thereon by the spring action of the loops in gripping a globe.

It is a further object of the invention to provide a shade and mounting therefor, the latter including bulb gripping loops as aforesaid, in which the shade is made entirely of plastic material, and therefore contains no wire ring to serve as a torque anchor for said shanks.

The invention is illustrated by way of example in the accompanying drawing in which:

Figure 1 is a view in top elevation showing the mounting as applied to the lamp shade.

Fig. 2 is a view in central vertical section taken on the line 2-2 of Fig. 1.

Fig. 3 is an enlarged fragmentary detailed sectional view taken on the line 33 of Fig. 2 and showing the details of construction of the lamp shade mounting.

Fig. 4 is a diagrammatic end elevational view of the mounting of the invention showing the bulb engaging loops thereof in full lines as relaxed and in broken lines as when these are sprung apart to admit an electric bulb therebetween for mounting the invention on said bulb. This illustrates the function of the torque anchors provided on the ends of the wire shanks which are held by saddle clips against rotation about the axes of such shanks to retain springiness in said bulb gripping loops.

Fig. 5 is an enlarged edge elevational view of 2 one of the saddle clips of the invention this being taken in the direction of the arrow 5 in Fig. 4.

Fig. 6 is an enlarged vertical sectional detailed view taken on the line 6 6 of Fig. 1.

Referring more particularly to the drawing, It! indicates a frustoconical lamp shade which is preferably made of translucent material such as plastics. It is provided with a skirt II and a circular rib I2. This rib I2 at diametrically opposite sides is formed with a boss I2. The skirt II may be embellished in any desired way to provide ornamentation and is designed to be mounted detachably on an incandescent light bulb. The mounting for the shade upon the bulb is designated at I3 and comprises two complementary loops I4 and I5 which are made of wire and are threaded through a ring I6. This ring is preferably made of flat stock so that it wil1 be rigid. The opposite ends of the loops I4 and I5 terminate in shanks I1 and I8. These shanks lie parallel to each other and are formed with outturned torque anchors I9 and 20, respectively, which are bent at right angles to the shanks I1 and I8 and are engaged by tangs H and 22, respectively, of a saddle clip 23. The body portion of the saddle clip 23 is formed with tangs 24 and 25, respectively, which may wrap around the shanks I1 and I8 and secure the shanks in position while holding the torque anchors I9 and 20 so that they project in opposite directions from each other and lie flat against the body of the saddle clip 23. The tangs 2I and 22 are formed integral with the body of the clip 23 and are folded upon said body, as shown in Fig. 4, so that the tangs will lie in a fixed spaced relation horizontally. Attention is also directed to the fact that the body portion of the saddle clip 23 and the tangs 2| and 22 are spaced vertically from each other to provide a recess 26 which may receive rib I2 and the diametrically spaced bosses I12 carried thereon.

In operation of the present invention the structure is formed as shown in the drawing and the mounting I3 is assembled as indicated particularly in Figs. 1, 3 and 4. When the mounting structure I3 is assembled as shown in the drawing the loops I4 and I5 may be flexed together in the ring I6. With the device thus compressed, one of the saddle clips 23 is brought to register with the annular rib I2 so that the top of the saddle rests upon the rib and the tangs 2| and 22 extend beneath the rib. The device is now allowed to expand to shift the other saddle clip 23 into a similar gripping relation with a diametrically opposite portion of the rib l2. The

mounting as a whole relative to the shade on the axes of the shanks l1l8 and (2) anchor these shanks against their individually turning in response to the torque imposed. thereon by the spring action of the loops l4 and [.5 when spread tointroduce a light bulb therebetween.

tive plastic lamp shade having 'no metal therein,

yet which is equipped with a mountingcof the.

double Wire loop type fulfilling all the requirements ofuspringaotionand stability and which may bebu-ilt andassembled at a, relatively low cost.

While I havelshown thepreferredform ofmy invention.as,now ,known to me, it will be understood that various, changesimay be made in combination, construction and arrangement of 1 parts by thoseskilled: in the art, without departing from thespirit oithe invention asclaimed.

Having thus described my invention, what I claim and desire tosecure by Letters Patent is:

1. Ina lamp. shadeadapted. to be mounted directly upon an. electric bulb, the combination of a plasticlamp shade having a rib formed integral therewith to extend inwardly therefrom; a pair of spring wire bulb engaging loops; a ring uniting said loops by the terminal sections of the latter extending through said ring and being bent to form pairs of shanks extending from said ring to diametric opposite portions of said rib, the shanks of each' pair lying side by side; torque anchors embodyingend portions of said shanks bent therefrom in opposite directions; saddle clips, the body of each of which'overlies a pair of said torque anchors and a portion of the adjacent pair of shanks; tangs bent from the body of each such clip to embrace the adjacent pair of shanks; and tangs bent from the body of each clip and passing around and under adjacent torque anchors and the adjacent portion. of said rib whereby said tangs cooperate with said clip bodies in uniting saidshade with the balance of said combination 4 V V and preventing substantial rotation of said anchors about the axes of said shanks.
