The

In the drawings: covering is secured in said position by cords 28 50 Fig. 1 is a perspective view, partly in section, of and 30 which pass through aligned apertures in a lamp shade embodying one form of the present the pleats of the covering in the customary maninvention, part of the covering material being ner and hold said covering against the upper omitted for the sake of clearness and illustration; and lower inner rings I2 and It Since the Figs. 2, 3 and are fragmentary. perspective frame members, that is, the upper and lower outer rings I4 and I8 overlie the opposite edges of the covering, axial displacement of the covering in relation to the frame is prevented. Hence, it is unnecessary to wind the attaching cord 30 about the lower frame ring, as heretofore, although this can be done if so desired. It will be noticed that the location of the frame members I 4 and I8 outwardly beyond the adjacent edges of the frame covering and substantially in alignment therewith not only serves to prevent relative axial displacement of frame and cover, but what is even more important, serves to protect said edges of the cover against tearing, bending or other damage.

In the form of the invention illustrated in Fig, 2, the frame of the lamp shade 32 comprises upper and lower annular frame members 34 and 36 connected by rods 38. Said frame members 34 and 35 are of angular formation in cross section, and each comprises a substantially horizontal flange and a substantially vertical flange, frame member 34 having horizontal and vertical flanges 40 and 42, respectively, and frame member 36 having horizontal and vertical flanges 44 and 46, respectively. It will be observed that the pleated shade cover 48 has its inner folded portions positioned against said vertical flanges and that the horizontal flanges 40 and 44 of the frame members extend outwardly over the opposite edges of said cover. Cords 49 and 50 passing through aligned apertures in the pleated cover 48 serve to hold the latter in position on the frame, said horizontal flanges 40 and 44 preventing axial displacement of said cover in relation to the frame.

In Fig. 3 the frame of the lamp shade 52 may be constructed in the same way as the frame of the lamp shade I0 illustrated in Fig. 1 but as here shown the cover 54 is composed of flat unpleated sheet material. Said cover is held in position by the engagement of the side edges thereof between the pairs of rings 56 and 58. The material of the cover is sufiiciently stiff and flexible for this purpose. Said cover may be held in position on the frame by securing the opposite ends of the cover in overlapping relation with the cover positioned snugly against the frame rings 56 and 58, the outer rings and 57 preventing axial displacement of the cover. Alternatively, said cover may be adhesively secured to the outer peripheral portions of rings 55 and 58, especially when the latter are made of or are coated with non-metallic material which would facilitate the adhesive bonding of said cover to the rings. Thus, for example, the rings 50 and 58 may be made of wood, Celluloid, phenol condensation products, etc., to which the cover 54 may be readily adhered by means of an appropriate adhesive.

The lamp shade 62 illustrated in Fig. 4 is similar to the shade illustrated in Fig. 2, but as in the case of the lamp shade 52, shown in Fig. 3, cover 64 is composed of unpleated or flat sheet material. The upper and lower annular frame members 56 and 68 are flanged vertically and horizontally and thus may be combined with the cover 84 in the same manner as the flanged frame members are associate-d with the cover 48 of lamp shade 32. However, as here shown, the attaching cords are dispensed with and instead the cover 64 may be secured in any suitable way, such as those described in connection with the description of shade 52. Like, the latter, shade 62 may comprise non-metallic frame members 66 and 68, and more particularly, said frame members may be made of such materials as wood, Celluloid, phenol condensation products, etc.

In Fig. 5 there is illustrated a lamp shade I0, the frame of which is similar to the frame of lamp shade 32, and as here shown, comprises an upper flanged ring I2, a lower flanged ring I4, and connecting rods I6. The pleated cover 18 is secured in position about the frame by a plurality of metal clips or staples 80 passing through the coverlapping end portion of the cover. It will be understood, of course, that the cover 18 need not be pleated, but may be made of flat material like the cover 54 of the lamp shade 52. The frame members 12 and may be made from strips of drawn wire of angular form as shown, a suitable length of such wire being bent into circular formation and their ends soldered together as indicated by the reference numerals and 84 for the rings and I4, respectively. A conventional lamp fixture 86 of any suitable form may be secured to a vertical flange of the upper ring I2. It will be noticed that the horizontal flanged members of the frame members extend outwardly beyond the edges of the cover I 8 and thus protect the latter against damage and also hold the cover in proper relation axially of the frame without additional attaching means.

The lamp shade 90 illustrated in Fig. 6 is similar to the lamp shade 62 with the exception that the cross rods of the frame are eliminated and the cover 98 is secured to the flanged rings 52 and 94 by means of rivets or eyelets 96. It will be understood that such cover is made of material such as stiffened cloth or parchmentized paper which is self-sustaining and stiff enough to hold the rings 92 and 94 in spaced relation. It will be understood also that a suitable lamp fixture, such as the lamp fixture 86, will be connected to the vertical flanges of the upper ring 92 in the manner illustrated in Fig. 5 in connection with lamp shade Fig. '7 illustrates a lamp shade frame which may be used in accordance with the present invention, for example, for the frame of lamp shades, 32, 62 and As here shown, the frame comprises an upper ring I00 and a lower ring I02, each made of sections of sheet metal strips. The upper ring member I 00 has a curved beaded edge I04, while the lower ring member I 02 has a flattened beaded edge I 06. Said rings are connected by metal strips I 08 which are provided with tongue portions I I0, tongue portions of three of the strips passing through circumferentially spaced slots I I2 in both rings in the manner illustrated in Fig. 9. As illustrated in Figs. 8 and 10, the ends of the rings I00 and I02 overlap each other and are provided with aligned slots I I4 and I I 6 respectively, through which the tongue portions I I 0 of one of the strips I 08 extend for holding the ends of said rings together and also for connecting this particular strip to the rings. The frame thus constructed may be produced at low cost and may be used in the same way as the frames illustrated in Figs. 2, 4 and 5, the frame cover (not shown) being mounted so that the inner surface portions thereof bear against the vertical flanges of the rings I00 and I02, and the horizontal flanges I04 and I 06 of said rings pro jecting outwardly beyond opposite side edges of the cover to protect said edges and to hold the cover in proper position on the frame. It will be understood that a conventional lamp fixture may be connected to the ring I00 in any suitable Way preferably by soldering the ends of the fixture to the inner surface of the ring I 00. However, when the frame member is non-metallic, or if for some other reason a soldered connection is not desired, the lamp fixture may be connected at its ends to the frame member in some other manner, as for example, that illustrated in Fig. 13. As here shown, the wires 83 of the lamp fixture 86 are provided with offset ends which are received in non-circular slots 81 in the vertical flange, at diametrically opposite points. As illustrated in Fig. when the lamp fixture comprises a single wire 89, the offset end portions 9| thereof are flattened to thereby hold said wire against rotation when the wire is circular.

In accordance with another form of the present invention, the lamp shade I 20 (Fig. 11) comprises a pleated cover I 22 having a plurality of aligned apertures, here shown as elongated slots I24 adjacent the opposite edges of the cover. A band I passes through the slots adjacent the upper edge of the cover, and a band I28 passes through the slots adjacent the lower edge of said cover. Said bands may be made of metal or of non-metallic material, such as Celluloid, fishbone, wood, or any other suitable material which may be bent into circular configuration. It will be understood that in making a shade of this type, a suitable length of the pleated material is provided with slots I24, and that the bands I 26 and I28 are passed therethrough and bent into proper form and then connected at their ends in any suitable way. After the covering material is 'assembled on the bands a lamp fixture I 30 may be secured to the upper band in any suitable way, as for example, that shown in Fig. 12, according to which the ends I32 of the fixture wire are bent around said band.

While I have shown several embodiments of the invention, it will be understood that the latter is capable of other specific embodiments and that certain variations in the constructions herein shown may be made without departing from the scope of the present invention as defined by the appended claims.

What I claim and desire to secure by Letters Patent is:
