A TTORNE Y cutting the coverings Patented Jan. 17, 1933 ALFRED BURKE, OF NEW YORK,

OF NEW YORK, N. Y., A. CORPORATION OF NEW YORK LAM]? SHADE Application filed .iui 'ao,

- This invention relates to lampshades and more particularly to shades having coverings of parchment paper or the like. Among the objects of the invention is to provide a shade of attractive appearance which may be inexpensively manufactured and assembled in large quantities at a very low cost in both labor and material. The paper coverings of shades of this character are generally made wider or of larger diameter at the bottom thanv at the top. As at present manufactured, considerable waste material is produced in from'sheets of stock. My invention contemplates the provision of a covering of such form and construction that it may be cut from a strip or sheet of paper without any material waste.

Furthermore, in the ordinary lamp shade of this type the covering is usually supported on a wire frame and is held thereon by lacing the covering with a cord around the frame or by fastening it to the frame with strips of gummed paper. According to this invention I provide a lamp shade construction wherein the customary frame is dispensed with, and in which the covering is 'provided with locking means whereby it may be readily and securely fastened to a supporting ring. Other objects and-advantages of the invention will appear from the following description thereof, reference bein had to the accompanying drawing, in whic Figure. 1 is a perspective view of one form of lamp shade embodying my invention;

' Fig. 2 is a fragmentary sectional view thereof on an enlarged scale;

Fig. 3 is a perspective view showing the covering in part attached to the supporting ring;

Fig. 4 is a detailed plan view showing the meeting edges of the covering attached together; and

Referring to the drawing, 10 indicates the covering member of the shade, which covering member is made of a fiat strip of parchment paper or like material having parallel upper and lower edges 11 and 1-2 and of such of the lamp shade form that a plurality of. the covering may 1532.

be successively cut from a sheet or strip of paper of suitable width without any material waste. As usually made, the coverings of shades of this character have curved upper and lower edges'of difierent curvature, the lower edge being considerably longer than the upper edge. The form of the coverings heretofore used is wasteful of material in cutting and does not permit of as many coverings being but from a strip or sheet of a given size as do my improved coveringsr To provide coverings which in their. completed shape will be smaller in diameter at the top than at the bottom, I form the paper strip 10 with a series of scorings disposed at intervals'along its length as shown in Fig. 5. Each scoring preferably consists of a central vertical score 13 and a pair of downwardly converging scores 14. The paper strip thus scored is subsequently bent to form a series of inwardly extending upright folds 15 which folds are deeper at their tops -than at their bottoms, thus forming a shade which in its completed form is wider or of greater diameter at the bottom than at the top.

It will be observed that the paper strip 10, in between each pair of scores 14 and adjacent its upper edge, is provided with a pair of oppositely disposed holes 16-16 which holes are connected together by means of a pair of downwardly converging slits 17 said slits meeting at the central vertical score 13 and afi'ording entrance to the holes for the purpose hereafter described.

18 is a wire 'ringupon which the covering issupported. The ring is provided'with spi- N. Y., ASSIGNOR TO THE PARCHLITE CORPORATION, I

der arms 19 which carry a suitable fixture for attaching the shade to a lamp. In the present:

instance this fixture comprises a pair of spring clips or loops 20 adapted to clam overthe bulb or globe of an electric lamp. n fastening the covering 10 to the ring 18, as illustrated in Fig. 3 of the drawing, the slits 17 of each fold 15 are in turn hooked over the 'ring so that the ring engages in and'passes through each pair of holes 16. This provides a very rapid and easy method of attaching the covering to the ringwithoutthe necessity of lacing or otherwise fastening the covering in place. After the covering has been placed on the ring, the meeting marginal edges 21 and 22 of the covering are fastened together by means of rivets or eyelets 23, as shown in Fig. 4, or in any other desired manner.

The slits 17 formdownwardly extending hook-like portions 24 in the body of the covering 10. When the covering is placed on the ring these portions 24 hook over the ring and prevent any accidental displacement of the covering laterally of the ring, it being understood that when the covering is applied to the ring the edges of the slits 17 spring together and thus these slits, together with the hook-like portions 24, constitute means for effectually locking the covering in place onthe ring.

It is to be noted that my improved lamp shade has only a single supporting ring at its top and does not embody a complete frame as is usual in lamp shades of this character.

Various modifications in the details of the construction herein shown and described may be made without departing from the spirit or scope of my invention.

What I claim is 1. A lamp shade comprising a supporting ring, a paper covering having substantially parallel upper and lower edges, said covering having inwardly extending folds at intervals around its periphery, said folds being deeper at their tops than at their bottoms and tapering lengthwise, oppositely disposed holes in the walls of the folds near their tops through which holes the supporting ring passes, slits converging from the holes and meeting at the inner edges of the folds to permit of inserting the ring into the holes, said slits forming hook-like port-ions in the body of the covering strip which hook-like portions extend inwardly over the supporting ring and lock the covering on the ring against lateral displacement.

2. A lamp shade comprising a supporting ring. a paper covering having inwardly extending folds at intervals around its periphery, said folds being deeper at their tops than at their bottoms and tapering lengthwise, oppositely disposed holes in the walls of the folds near their tops through which .holes the supporting ring passes, slits c0n-' verging from the holes and meeting at the inner edges of the folds to permit of inserting the ring into the holes, said'slits forming hook-like portions in the body of the covering strip which hook-like portions extend inwardly over the supporting ring and lock the covering on the ring against lateral displacement.

3. A lamp shade comprising a supporting ring, a paper covering having inwardly extending folds at intervals around its periphery, said folds being deeper at their tops than at their bottoms, oppositely disposed holes in the walls of the folds near their tops, through which holes the supporting ring passes, and slits converging downwardly from the holes and meeting at the inner edges of the folds to permit of inserting the ring into the holes.

4. A lamp shade comprising a supporting ring, a paper covering having inwardly extending folds at intervals around its periphery, oppositely disposedholes in the walls of the folds near their tops, through which holes the supporting ring passes, and slits converging downwardly from the holes and meeting at the inner edges of the folds to permit of inserting the ring into the holes.

5. A lamp shade comprising a supporting ring, a paper covering having inwardly extending folds at intervals around its periphery, oppositely disposed holes in the walls of the folds near their tops through which holes the supporting ring passes, and slits connecting said holes to permit of inserting the ring into the holes.

Signed at New York city in the county of New York and State of New York this 29th day of July, A. D. 1932.
