7 Claims.

My invention relates to a method for shaping the wires used in the construction of articles of various kinds as for lamps of different sorts, wire novelties and the like, and an object of my invention, among others,.is the provision of a process whereby such articles may be made in a rapid and efficient manner and more especially a method whereby they will have an extreme degree of accuracy in the shapes and forms finally produced. A process for accomplishing my purpose and in the practice of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings in which Figure 1 is a view of a piece of wire adapted 15 to be formed to shape to constitute a portion of a frame for a lamp shade.

Figure 2 is a view illustrating the operation of securing the ends of the wire together, this constituting one of the initial steps in the process 2-9 of forming a frame.

Figures 3 and 4 illustrate the formation of the wire in a succeeding step in the process.

Figures 5 and 6 illustrate further succeeding steps in the process, and

25 Figure '7 illustrates the .final step of forming this last mentioned frame.

Figures 8 and 9 illustrate one of the initial and the final steps in the process of forming a frame which is generally round in shape.

3Q Figures 10 and 11 illustrate steps in the formation of a wire to constitute a frame of still adifferent shape.

Figures 12 and 13 illustrate a step to form the frame shown in Fig. 11 into still another shape.

Figs. 14 and 15 illustrate steps to form the frame of Fig. 13 into a frame of still another shape.

Figs. 16 and 17 illustrate the manner of forming a frame to a shape different from that illus- 40 trated in the preceding figures, Fig. 18 illustrating the finishing step in the operation of slightly changing the shape of the angular parts of this frame.

Figs. 19 and 20 illustrate the manner or forming the frame shown in Fig. 16 into still another shape.

In the manufacture of shades for electric lamps which are supported on standards for table use or which are placed on the floor, such shades 50 commonly consist of wires, one at the top and the other at the bottom, to form stiffening members for the fabric or paper or similar material constituting the body of the shade, these twomembers of the frame being commonly of the {P3 same shape but of different sizes; or they may be for both of the same size. In the construction of these frames it has been common practice to shape a length of wire into the form required and then to join the ends by welding or otherwise. In this manner of forming the wires it has been diffi- 5 cult to obtain a. frame with the different portions or' sides thereof of exactly the same shape throughout with a result that such frames are more or less unsymmetrical, and this difficulty is emphasized when an attempt is made to shape 10 a piece of fabric or paper comprising the body of the shade to fit the frame. As the difference in shape of each of the two frames on different sides and the difference in shape of the two frames which do not exactly match causes the 15 sides of the body of the shade to be unsymmetrical.

By the practice of my improved method I am enabled to obtain frames which are substantially of the same shape on all sides and also to obtain 20 the top and bottom frame members to very closely match one another and therefore the sides of the body of the shade are quite symmetrical, thereby producing a shade of very symmetrical and pleasing appearance.

In the formation of wire frames it is a comparatively simple matter to produce the round or simpler geometrical forms, as square, hexagonal, octagonal, and the like, but a difliculty arises when attempts are made to impart more complicated shapes to such forms, and it is in the production of these more complicated forms that my improved process finds its adaptability, such invention residing in the joining together of the ends of a wire after the simple forms above referred to have been obtained, and then imparting more complicated shapes to such forms.

In the accompanying drawings the numeral 20 (Fig. 1) denotes a piece of wire cut to the desired length and having its ends 2i adapted to be joined for the purpose of welding or otherwise securing such ends. This wire is then formed into a simple geometrical shape or round form and the ends are then secured together as by means 4 of welding devices 22, as shown in Fig. 2. As 5 shown in Figs. 3 to 7 this simple square form has a bend 23 formed in each of its four sides as by means of dies 24 and 25, the frame, in the formation of the bends in different sides, being placed between holders 26 that properly position the frame so that the bend 23 will be located in the center of the side in which it is formed. The bends are successively formed, preferably in numerical progression, around the four sides of the frame with a result that the frame is symmetrical as to its four sides and the bends formed therein.

The matching frame is formed in the same manner, and if of a different size, the holders 26 are placed a distance apart equal to the length of each of the four sides of the frame, and the two frames will so closely match each other that any difference in shape cannot be detected by the naked eye, and when the body of the shade is folded to the shape of the frame such folds will be very symmetrical.

In the frame shown in Figs. 8 and 9 a round form 2'! is first made with its ends joined, and

bends 28 are formed on diametrically opposite sides as by means of dies 29 and 3G, a guide 3! being employed as a means for properly positioning the wires relatively to the forming dies, the resulting shape of the frame being shown in Fig. 9.

The frame illustrated in FigsglO and 11 is square as in the frame first herein described, and dies 32 and 33 are employed to create offset bends 34 on each of the four sides in the centers thereof, the holder 26 being employed to properly posltion the frame in the bending operation.

This same frame may be further shaped, if desired, by creating a second offset bend 35, as by means of dies 36 and 31, extending across that first made, the holders 25 being used'to properly position the frame for operation of the guide. The resulting shape of the frame is shown in Fig. 13.

The frame shown in Fig. 11, or that shown in Fig. 13, may be shaped into still another form by tion the frame on the dies.

rounding the corners of the original square figure, as by means of dies 38 and 39, the resulting shape of the frame, as to the form of Fig. 13, being shown in Fig. 15.

The original simple form of the frame shown in Figs. 16 and 1'7 is hexagonal, the ends being joined, and by means of dies 48 and 4| the wire is formed to the preliminary shape shown in Fig. 17, holders 42 being employed to properly posi- To slightly change this shape the angular indentation 46 maybe made more acute by the dies 41 and 48, as shown in Fig. 18.

In Figures 19 and 20 the frame is shown produced from an original octagonal form 49 as by means of dies 43 and 44, the resulting shape of the frame being shown in Figure 20. In the formation of this frame guides 45 are employed as in the operation of making other forms hereinbefore described.

While the invention is illustrated and described herein in connection with certain round and geometrical forms it will be understood that the invention may be equally applied to geometrical forms of various shapes other than those described herein, and the invention may therefore be considered as equally applying to such other forms within the scope of the appended claims.

I claim:

2. The method of forming a wire frame that consists in joining the ends of the wires to comprise the frame, and then successively imparting shape to the different sides of the frame.

3. The method of forming a wire frame that consists in producing an initial form with the ends joined together, and then imparting further shape successively to the different sides of the frame.

4. The method of forming a wire frame that consists in producing an initial form with the different sides of suitable shapes, then joining the ends of the Wire comprising such frame, and then imparting additional shape successively to each of the several sides of said frame.

5. The method of forming a frame for a lamp shade that consists in producing an initial form with all of the sides of the same shapes, then joining the ends of the wire together, and then in numerical progression imparting different forms successively to the several sides of said frame.

6. The method of making a wire frame that consists in forming a length of wire into geometrical shape and permanently joining the ends thereof and then changing the shape to another geometrical form by bending the wire at different points at different times to complete the shape.
