LAMP SHADE.

applmmon and .imaary 21, 1925. serial no. 3,755.

This invention relates to lamp shades and more particularly to shades constructed of silk, parchment or the like, stretched u on a wire'frame to give the same leasing form and dimensions. Shades of is character are usually round or oval and oftentimes tapered from the' top toward the bottom.

It is the object of this invention to provide suitable means for associating photographic transparencies with these sha-des which will at the same time maintain the transparency in a vcurve corresponding to the curve of that portion of the lamp shade.

A further obiect of the invention is to provide a translucent light diffusing member which is e ual in size to the transparency and is placed eneath said transparency and the source of light over which the shade is adapted to `be placed.

With these broad general objects in view, the invention will now be described by reference to the accompanying drawing in which,

Figure 1 is a perspective view of a lamp shade embodying this invention.

Fig. 2 is a vertical-cross section of a portion of the lamp shade and taken through the photographic transparency online II-II of Figure 1.

Fi 3 is a modified form of the way in whic the photographic transparency may be applied to a lamp shade.

Fig. 4 is a stretch-out perspective view of the several parts of this invention and showing the lamp shade in a fragmentary way.

Fig. 5 shows a modied form of a transparency which may be applied to the lamp shade. p

Fig. 6 is an enlarged detailed section of ythe frame inter-clamping means.

Fig. 7 is a face view of the same showing the way the spur shaped clamps ma be prssed from one of same frame mem rs, an

y Fig. 8 is a horizontal section of the plotogra hic transparenc taken on line II II of Fig. 5 and7 showing in particular the way all members conform to the general curvature of the lamp shade.` With reference at this time to the drawings in detail wherein similar reference characters refer to like parts throughout the several views/and wherein 9 is the ordinary lamp equipped with the well known shade which 1s constructed by utilizing a wire frame 10 which is covered with any desired lwill present a completely black su material lsuch as parchment, silk or other cloth 11.

This shade need not be especially conj structed .for use with the photographic transparencies forming al part of this invention, ut may be stretched with any degree of curvature over frame 10. These photographic transparencies are preferably made upon a pliable material 12 which is slightly larger in size than the opening 13, out into material 1,1 when the transparencies are being applied to the shade. A translucent pliable sheet 14 is preferably, though not necessarily, placed in juxtaposition with trans- `parency 12 and between said transparency and the illuminating means of the light not here shown,

Numerous ways of securing transparencles 12 and sheet 14 may be devised'for securing the same over opening 13. These transparencies and openings may also be made .in any desired4 shape and the same placed in any position or location over the surface of the lamp shade walls. For the purpose of illustration, the preferable Way o mounting transparencies 12 and sheet 14 is shown to be a frame of metal or some other suitable material made up of a front fra-me 15 and a rear frame 16. The openings in frames 15 and 16 are slightly smaller'than the opening 13 in shade'11 and slightly larger than the outside dimension of transparency 12 and sheet 14. Rear frame 16 may or may not be ofi-set as shown in the drawings, and the method of securing the two together may be varied. This method is shown here to be a series of s urs 18 stamped out of front frame 15 and) adapted to pass rearwardly through materiall 11 and thence through openings 19 registering therewith and formed in rear frame 16. This structure binds material 11 around the edges of opening 13 and precludes any fraying, tearing or running' of the fabric. As shown in Fig. 3, the transparency and translucent sheet 14 may be glued directly together with fabric 11 between the same. To remove the unfinished appearance when this method is em loyed, any suitable binding such as a metal ic frame or metallic lace 20, may besecured around the outer edges of transpar-,

ency 12 as shown.

It is a recognized fact that tralparencies ace when no light is laced ehnd them.l If this feature 1s un esirable, the shade may be constructed with a covering of voile 21 stretched over the transparency and frame only, or may be bound to the frame as is the material 11 to form a complete outer covering over the entire shade which conceals toga lar e extent the transparencies when the light 1s not lit.

As is shown in Fig. 8, the Jframes are formed to conform to the curvature of that particular portion of the shade to which the transparency is to bey applied. The transparency being pliable, will be held securely with its tace conforming to the curvature of said shade.

It is understood that lnany changes and modifications may be made in this invention, and it is desired not to be limited in its construction except as deiined in the appended claims.

What I claim is:

l. In a lamp shade of the class described,

having walls oi cloth or the like. said walls having'openings cut therein, photographic v transparencies positioned over said openings,

a translucent sheet of a size equal to said transparencies in juxtaposition thereto and common means for holding said transparencies and translucent sheets over said openings and conforming the same to the general contour of said shade cpinprising a front and a rear .frame adapted to interlock and engage said cloth walls therebetween.

2. In a lamp shade oi3 the class described, having a frame, cloth or the like stretched vover said frame to iorm walls, said walls being provided with openings, said openings each having a photographic transparency thereover, a translucent sheet behind said transparency, and an inner and an outer frame conforming to the shape of said vopening adapted to retain said transparency and said translucent sheet therebetween in position and in a position conforming to the general contour of said shade.

3. In a lamp shade of the class described,

, .having a frame, cloth or the like stretched over said frame to form walls. said walls being provided with openings, said openings having a photographic transparency registering therewith, and an inner and an outer frame for retaining said transparency in the registered position, both of said frames being curved to correspond to the general curvature of said shade at said opening whereby the said transparency is held in a curved position corresponding 'to said shade.

4. In a lamp shade of the class described, having a frame, cloth or the like stretched over said frame to form walls, said Walls being provided with openings, a pliable photographic transparency registering with each of said openings, and means for retaining said transparency in the registered position comprising a pair of frames, means integral with one of said frames for piercing said cloth and engaging the other of said frames, wherebyA said transparency is given a curvature correspondingto said shade, and said cloth or the like is retained in its normal .position around said transparency.

5. In a lamp shade of the class described, having a frame, cloth or the like stretched over said frame to form walls, said walls being provided with openings, a pliable photographic transparency registering with each of said openings, and means including a pair of registering metallic frames for holding said transparency in place, said fra-mes having a curvature corresponding to the curvature of said shade at said opening for maintaining the transparency in the same degree of curvature as said shade.

6. In a lamp shade of the class described, having a frame, cloth or the like stretched over said trame to form walls, said walls being provided with openings, a pliable photographic transparency registering with each of said openings, and means 'for securing said transparency to said walls, said means being adapted to protect the material in said walls from iraying or running at the edges formed by the cutting of said opening.

7. In a lamp shade ofthe class described, having a frame, cloth or the like stretched over said frame to form walls, said walls being provided with openings, a pliable photographic transparency registering with each of said openings, a frame supporting said transparency and gripping said walls at the edge of said opening and an outer covering forming a part of said lamp shade stretched over said transparencies whereby the same are concealed when said lamp shade is not illuminated from the inner side.

In .testimony whereof I h'ereunto at'ix my signature this 17th daqy of January, 1925.
