This invention relates to lamp shadesland more particularly to that class of shades especially adapted for use with and mounted on the electric lamp of. the ordinary form.

The object of this invention. is to provide an electric light shade for advertising or decorativepurposes of such construction that the same may be made in quantity in the flat and folded to form when so desired. A coin structionof this nature will allow the shades to be packed in a comparatively small space for shipping and storing and eliminatethe likelihood of breakage in both shipping and store display. p a

With these and other objects in view this invention resides inthe combination and arrangement of parts more particularly do shade with the form of cap illustrated'in scribed in the following specification and'illustrated in the accompanying drawi11gs, in which Figure 1 is a view in plan of a blank from which the shade is constructed;

' Figure 2 is a sectional elevation showing the shade on an electric lamp;

Figure 3 is a top plan. of the shade;

Figure a .is a View in'plan of a modified form of cap used with this shade;

Figure 5 is a sectional elevation showing a Figure 4 on an electric lamp; and;

F igurefi is a view in plan of another modilied form of cap used with this shade.

Referring to the parts by reference characters, 1O designates'a strip of material having a plurality of'downwardly proyectmg tabs 11 on one end thereof and a series of slits 12 formed adjacent the opposite end for the reception of the tabs 11 when the strip is folded to form, as illustrated inFigure 2. A cap or top piece 13 of metal has a table extending therefrom the same being permanently secured approximately midway the length of the strip 10 adjacent one of the 1011- gitudinal edges thereof. A series of bendable tongues 15 extend from the cap 13 and are inserted through slits 16 formed in the strip 10 when the shade is folded to form. The cap 13 has an opening 17 therein of such dimensions to receive thesocketend of an electric lamp and thus support the shade on the lamp. I I

In Figures 4; and 5 a modified form of'supporting cap ortop piece is illustrated. The top piece previously described supports the shade from the socket end of the lamp while in this form the same may be supported by thesocket end or the opposite end of the lamp. This is" accomplished by providing a pair of semi-circular spring lamp-engaging arms 19 that are cut from the cap 13 along the margin of the lamp receiving opening 17 If it is desired to support the shade from the socket end of a lamp the spring arms 19 are placed in the position as shown in F igure l, that is parallel with the cap 15 and thereby provides a'somewhat restricted lamp re ceivin onenin and when adaptin the same a 1. c l c to support the shade from the opposite or large end of a lamp the spring arms 19 are bent awayfrom the cap 13, as shownin F 1gure 5, and thus provide a somewhat enlarged lamp receivingopening. It will be noted when the semi-circular arms 19 are in the latter position they are engaged with the lamp on opposite sides thereof to securely retain the shade in position and reduce the tilting tendencies thereof'to a minimum.

A still further modification of this invention is illustrated in Figure 6 wherein the cap 13 is provided in the center thereof with an indention 20 adapted to receive the teat 21 found on the ordinary electricbulb. Radial fins or blades 22am struck up from the cap 13 so that a shade provided with this form ofcap will be rotated about the lamp blades 22.

by the heat of the lamp and the deflecting lamp shade of, substantially cylindrical form has beenprovided, the supporting cap pref-H erably formed of metal while the stripof material forming the side wall of the shade may be paper, parchment; fabric, metal or other suitable material. This material may be to some degree transparent and ornamental or advertising matter could be printed thereon. Shades made in accordance with this invention could beshipped and marketed in a complete unit in fiat form and be folded into op erative form with theminimum effort withoutthe aid of additional fastening elements. 7 It will be appreciated that my invention is not limited to lamp shades of cylindrical form, as shown in the drawings, andthat-any other desirable shapes may be employed Without departing from the spirit and scope of my invention. 7

g: I f l; A lamp shade including a foldable side Wall a cap fixedly secured to said-side Wall and about which said side Wall adapted to be folded, means adjacent the ends of said sidewall for holding the ends thereof to gether when said Wall is folded, and a plurality of bendable tongues on said cap enga eable with said side wallwhen said Wall is timed "about said cap.

In testimony whereof Iaifi x my signature.
