Definitions

• This invention relates generally to the manufacture of lamp-fixtures and light-flttinga more particularly to those parts thereof which are used for modifying the light of the lampand/or for decorating the fixture, and has in view to provide a new method of producing such lampflxtures and light-fittings, as lustres, shades,
• a layer of flexible material thus obtaining novel decorative effects, especially when the lamp is lighted.
• Such shades also possess the advantage that their form may easily be changed or altered or modified at any time desired, and may also be stretched, rolled or folded for convenient packing or transport.
• Articles made according to this. invention possess also the advantage that in case any part thereof is damaged, this part mayeasily be replaced by another part without affecting the article as such and Without causing any detriment to its value.
• the invention consists in a method of preparing and producing translucent light modifiers of any desired shape, such as, lustres,'shades, globes, pendants, ceiling, wall or foot light flttings and the like and plates or parts for such articles, which comprises pasting or otherwise securing a layer of transparent material, such as glass, Celluloid or the like, onto both surfaces, respectively, of a layer of flexible material, such aspaper, fabric or the like, of any color or design, thus forming a sheet or strip of compound layer material, segmenting said compound material into a plurality of pieces of any desired a design, forming a number of such pieces to the desired shape of the article and retaining them in said shape in such a manner that they may readily be de-formed for convenient packing or transport of the finished articles and may easily be re-formed when desired.
• a layer of transparent material such as glass, Celluloid or the like
• the pieces of the compound layer material may be either separate from one another and associated with each other in a suitable frame or ring to hold them to the form of the article required, or a number of such pieces may be interconnected by portions of the flexible material lying between the said pieces of compound material, thus forming flexible hinge lines between them and the properties of flexibility at such lines and of substantial rigidity between such lines may be utilized in forming the articles to the desired shape.
• the formation of the pieces to the desired shape according to the present invention is preferably performed after the transparent material has already been secured upon the flexible material, as the division of a complete plate into a plurality of small pieces is easy and convenient, but articles or parts of them as listed above may also be produced of a plurality of individual pieces of transparent material being prepared in advance to the desired shape and afterwards pasted or otherwise secured on to a sheet or ribbon of flexible material, and when the latter method is employed, broken pieces of glass or the like goingto waste up to present may successfully be utilized.

• varare substantially as follows:
• the first manner is to paste one layer of transparent material onto one surface of the flexible material and to secure a second layer of transparent material onto the other surface of the flexible material after forming the article to the desired shape.
• the second manner is to paste the transparent as to enable the formation of the article.
• the third manner is to place the flexible material between two layers of strips or pieces of transparent material, and to secure all three layers to each other by means of a frame, screws or clips, without pasting while forming the article to the desired shape.
• the end of all the three manners is one, viz., to produce lamp-fixtures, light-fittings, shades or various other parts thereof or for same, in which the color or pattern of the flexible material be translucently and uninterruptedly visible through the transparent material, and which can be folded or stretched or taken to pieces, when desired.
• variously shaped lamp-fixtures, light-fittings, shades and the like articles may be formed from plates prepared according to my invention. Such articles may also be directly made of transparent material A combined with flexible material B,
• the second layer A" of strips or pieces of transparent material is then added and secured onto the other surface of the flexible material.
• Vaulted or conically shaped shades or the like articles may also be produced by the following manner: A sheet of flexible material B is to be prepared in the shape of a not complete circle, as shown in of the drawings, and onto such a sheet, strips or variously shaped pieces of transparent material A are pasted in an order suitable to form the desired shape of the shade.
• the formation of theshade is then effected by joining or pasting the ends Z Z of the flexible material B to each other.
• the strips or pieces of transparent material A are pasted onto the inner surface A" of the sheet of flexible material B, the strips or pieces have to be pasted at a certain distance one from the other, i. e., the strips for the inner surface A" must be smaller than the strips pasted on the outside surface A, thus enabling the formation of the articles in the desired shape.
• Strips or pieces may also be prepared so that the edges thereof are ground in a slanting position see A" of Fig. 5, and when such pieces are used for the inner surface A of an article, they may be pasted onto the sheet of the flexible material B matching piece by piece, so that when the article is formed in a round or otherwise vaulted shape, the slanted edge of one piece interfits With the slanted edge of the adjoining piece one supporting the other, thus holding the article in the predetermined shape (see Fig. 6). Wood or metal bars or the like'may also-be inserted or fitted between the strips A of the transparent material.
