, UNITED sA'rEs PATENT OFFICE;

EDMUND G. GEORGE, OF SPRINGFIELD, ILLINOIS.

naivrr srmnn.

Beit known that I, EDMUND G.'Gnoncn,

I a citizen of'the United States, and residing at Springfield, in the county of Sangamon and State of Illinois, have invented a certain'new and useful Improvement in Lamp- Shade's, of which the following is a Specificati'on.

jThisinvention relates to shades, dc fsignedespecially for use with incandescent lamps. and of the type having transparent or translucent sections or panels for softening the light and producing ornamental efi fects.

Prior devices of this classhave contemplated the use of glass panels or sections,

j k these being objectionable, however, not only because of'the cost incident to their use, but "also because ofthe fact that because of this cost they become a permanent fixturetunadaptable forready changing in instances where different colored light efiects are desirable, as in the instance of certain social functions. The use of glass panels is also objectionable for the. reason that they necessitate the use of heavy andexpensive frhmes 1 for holding them, and because the extreme weight of the resultant shade necessitates l the provision of special clamping devices for properly attaching them in position onthe lamp.

. "Thisinvention has for its objects to overi come the objcctionslnoted, by the production ofa simple, inexpensive shade of minimum weight, which may be readily applied inpofully hereinafter described.

In the accompanyingdrawin s; Figure 1 1s aside elevation of an electric amp fixture equipped with a shade embodying the invention; Fig.2 is a top plan view, partly in section, the section being taken on the line 2-2, Fig, 1; Fig, 3 is a vertical section taken on the line 3-3, Fig. 1, of the shade, showing the same applied to the lamp. fixture; and,

, Specification of Letters Patent.

Application filed July 12, 1915. SerialNo. 39,509.

Patented May 23, 1916.

Fig. 4 is a detail perspective view of the clamping means for holding theshade in place on the fixture.

Referring to the drawing, 1 designates an electric lamp socket provided, adjacent its lower end, with a peripheral flange 2, and fittedwith anincandescent lamp globe 3, these parts, which are foreign to the inven tion, being of the usual construction and material.

The lamp shade forming the subject matter of the invention consists of a cap 4:, a

skeleton body frame 5, and transparent or translucent sections or panels, 6, the latter being composed of heavy oiled paper, and

removably held in the frame 5 by means of downturned engaging portions or fingers 7 at the upper end of the frame, and upturned flanges 8 at the lower edge of the frame.

Thecap portion 4, which is formed from a. single piece or blank of thin sheet metal, and in a single operation, is provided with a central fixture receiving opening 9, a downturnedmarginal flange 10, and a plurality ofapertures 11 arranged at diametrically opposite points, and at a suitable spaced. distance inward from the margin of the cap,

there being provided at suitable points around the opening 9 and in the operation of forming the cap, radial tongues orfingers 12, having their ends bent upwardly and. backwardly upon themselves, thus to form springclamping fingers for engagement with thelamp socket 1 above the rib 2, as seen more clearly in Fig. 3.

The body 5, which is formed from a single blank of thin sheet metal having portions cut out to formsidev openings 13 through which the paper 6 is exposed, these openings being separated bysuitable webs 14, 15, 16 i and 17, of which thewebs 16 form the vertically disposed corners of the frame when the blank is folded in completed rectangular form, as indicated by dotted lines in Fig. 2, it being noted that when thus folded the meeting ends of the blank are united at one corner of the frame by means oftongues 18 formed on one of theWebs 16, and engaging throughslotted apertures 19 formed in the adjacent Web, While formed on the upper edge of the blank aretongues 20 corresponding in numberto, and properly positioned for engagement through, theperforations 11, for attaching the body frame to thecap 4. In the stamping operation incident to formation of the body blank, the latter is in cised atappnopriate intervals along its upper and lower'edge s, to provide for formation of the fingers"? and flanges 8, the metal which is to form these pests being folded inward 'ward respectively upon the webs and it ror engagement with the ad- 7 jacent edges of the sheets 6, as seen more clearly in Fig. 3, it being noted that coincident with the formation of the fingers 'i' there are provided at the upper edge of the body suitable ventiiating openings 21.

In practice, in orderfto apply the shade to the lamp fixture, the globe is removed andthe loWer e'nd of thelamp socket 3, positioned in the'opening 9, whereupon, by up? ward pressure on the shade, the-fingers will spring over the rib 2 and into clamping engagement with thesocket at a point above said rib, it being :Htoted, in this connection,

- that, owing to the extrteine lightness of the shade as a whole, the fingers 17. Win

quately serve for properly securing the shade in position on the lamp, the

shade is in position, the transparent or,

translucent panels 6 will appropriately soften or color the light radiated from the lamp, and when it is desircd'to change the panels to accord with a particular color scheme, or to vary the monotony 'incident to the continuous use of shade ofa certain color, "the paper sheets. or panels may be tible o In fact, it is the purpose in marketing the readily removed and replaced by others ofa (lifi erent color, the range of such changes being practically indeterminate and Suscep- 'being'made with very slight expense,

device, to provide a number of sets of panels 6 of difi'erentcolors, to be interchanged at will. It is evident thatthe several component parts ofthe shade are ofextreme simplicityin construction, and are so formed that they may-bereadily set up in completed form for use, and further, that they are all produced from light Weight material;

sme

whereby il Slevice as a Whole maybe inexpeusively predated 2 nd maybe applied to the lamp and prop rly supported thereon hf means of the Simplified form or g fips herein shown.

It is obvious that various changes ma be made in th dot-ails of construction Witheut ,departi ng {hm the spirit of this invem therci'bre, to be understood that ties if i thisjin-vention not to be limited to the specific GQHwtd'llQil-QQ shel Y!) sad described- Having thus described the inyention, what is claimed is: 7

1. A lamp shade comprising frame and a cap, each of said part brainstormed fr'rom a single sheet of materialplsaiil cap having an opening and a plurality of radial spring fingers projecting into said opening, and means for attaching the cap to the body. 2. A lamp shade comprising a body frame and a cap, each formed from a single sheet of material and having integral intrengaging portions for attaching the cap to the body, said cap having an opening and a mate o ed spring fingers p j n i to said r pe n a 3. A lamp sheds QOmprising a body frame and a cap,said body frame being formed from a single sheet of material and having enlarged panel openings, paper panels arranged in the body frame to cover said openings, and means on said body frame for holding the panels in place. v

4:. A lamp shade comprising a body frame and a cap, said body frame being formed from a single sheet of material and having enlarged panel openings, inturned engaging lips formed integral with said body frame at opposed sides thereof, and paper panels arra ged in the ody ame in engagement with said lips and to never said; openings.

In testimony whereof I atlia; signature this 28th day of May, 1915. I
