11 Claims. (Cl. 41-24) This invention relates generally to ornamentation, and has particular reference to pictures and designs formed in relief on deformable, initially flat, sheets of transparent, colored and opaque plastic or similar material, and to a method for making such pictures and designs to achieve a three-dimensional effect.

One of the objects of the invention is to provide a simple and effective method for making pictures and designs having three-dimensional characteristics, that does, not require special training or tools and whereby attractive and interesting results are readily attainable by the hobbyist or amateur.

Another object of the invention is a method of making pictures in relief on sheet material such as plastic and the like by the deformation of the sheet along curved and straight linear paths to provide depressed'and elevated areas of generally V-shaped section which produce a pronounced three-dimensional appearance.

Still another object of the invention is to provide a new and improved method of making decorative three-dimensional pictures and designs of distortable sheet material,

that may be displayed not only alone but advantageously in combination with materials of complementary or contrasting color tones to produce a wide variety of ornamental elfects.

Still another object of the invention is a method for producing pictures and designs in sheet material such as transparent, translucent, frosted and opaque plastic and the like, wherein the required materials for its execution are well-adapted to be arranged in kit form for amateurs,

hobbyists and children as well as for specially skilled individuals.

The above and other objects and advantages of the invention will become more apparent from the following description and accompanying drawings forming part of this application.

In the drawings:

Figure 1 is a perspective of an article of ornamentation made in accordance with the invention;

Figure 2 is a perspective view of the material on which a design is to be formed and the patterns used in forming Figure 3 is a perspective view showing one step in making the design shown in Figure l; and

Figures 4, 5 and 6 show alternate structures for mounting the design of Figure 1 in accordance with the invention.

The fabrication of three-dimensional pictures and 'de-- signs in accordance with the invention involves the distortion of a permanently deformable sheet material such as plastic and the like along predetermined paths and in such a manner as to cause the completed design to have substantial depth through the formation of alternate areas of elevation and depression of V-shaped section. The invention also includes means for mounting these threedimensional pictures and designs to accentuate the effect of depth and provide harmonious and contrasting color effects.

, 2,711,039 Patented June 21, 1955 Figure 1 illustrates a completed item that may be formed of a sheet of plastic material 10 such as cellulose acetate, cellulose nitrate, Bakelite, Vinylite or other similar material having readily deformable characteristics and form-retaining qualities. The alternate V-shaped effect obtainable with this invention can be observed along the edge 11 of the material 10 which shows alternate raised and depressed portions. For instance, the line 12 of the design is formed by the application of pressure along a path on the reverse side of the material while the adjacent line 13 is formed by the application of pressure on the front side of the material. This results in increasing the depth between the lines 12 and 13, and this may be further emphasized by displaying the finished product on a rigid backing or support, as will be described. Furthermore the design as shown in the figure may be formed on transparent, translucent, opaque, opalescent, or frosted material to produce any desired artistic effect.

' In making a product as illustrated in Figure 1, a line drawing of the design to be reproduced is first prepared on paper or similar material. This drawing may be Wholly original or copied from a photograph, print, painting or other artistic work. The lines are then divided into two groups, namely those to be in a raised position in the finished product and those to be in a depressed position. Each group of lines may then be transferred to a separate sheet of material such as paper or the like to form two separate but complementary patterns. These patterns are denoted by the letters B and C in Figure 2. The sheet of deformable material is denoted by the letter A in this figure.

By way of example, let it be assumed that the material A of Figure 2 is a transparent plastic so that the patterns B and C can be observed through the material. In this case the patterns B and C may be made on any type of paper orpaper-like material with the group of lines of one pattern being reversed relative to the group of lines on the other pattern. For example, consider the lines 12 and 13 of Figure 1. The line 12' on pattern C corresponds to line 12 of Figure l and appears at the righthand side of this pattern while the line 13" corresponds to line 13 of Figure 1 and appears on the left-hand side of pattern B. While the patterns B and C are shown on separate sheets of material it is quite apparent that they can be formed on opposite sides of a single sheet of opaque material or of a transparent or partially trans- A is placed over the pattern.

lines from the other. For instance, the groups of lines could be of different colors or one group formed in solid lines and the other in dotted lines.

Having prepared the patterns such as those shown at B and C in Figure 2, a resilient work surface is prepared as shown in Figure 3 on which the deformable sheet A is distorted to produce the three-dimensional effect. In the figure the work table such as a table top or the like is denoted by the numeral 14.. The resilient work surface 15 is placed on the table top 14 and is of course preferably slightly larger than the deformable material A on which the design is to be formed. This resilient layer may be of any suitable material such as felt, rubber, many layers of newspaper or cloth or any other yieldable material that is easily compressible under pressure. The pattern B is then placed on top of the resilient material and the transparent material As illustrated, the pattern B includes the group of lines that will ultimately form depressions in the finished article. Before proceeding with the actual deformation of the material A it is important to guard against any relative movement of the pattern and material. For this purpose guides or clamps may be used.

Deformation of the material may be accomplished by any suitable instrument or tool having an appropriately shaped end that will not cut or damage the material A. Such an instrument is illustrated in Figure 3 and includes a tapered. shank 16 of metal or the likev having a rounded endpart 17 that bears directly on the material A. and a suitable handle 18. As the lines of pattern B show through the material A, the tool- 16 can be guided over the material in paths corresponding to the lines of the pattern. At the same time sufiicientpressure is exerted on the tool to permanently deform the material along these paths. In Figure 3 the material is shown as having been deformed along line 19 while the line 2%) has been deformed part way. These two. adjoining lines. of depression form a gently rounded area 21 between them. These lines are also shown on pattern B of Figure 2 and the corresponding lines are denoted as 19 and in Figure 1 When all of the lines of pattern B are impressed in the material A, the material A and pattern B are removed and pattern C is placed in position on the resilient material 15. The material A is then turned over and placed on the pattern so that the depressions such as

lines

19 and 20 extend upwardly. formed in material A is properly aligned with the pattern C and the material is then deformed along, the lines of the second pattern. For example, the line. 22' of pattern C corresponds to the line 22 of Figure 1 and lies between lines 19' and 20' of pattern B- When this line is impressed in the material- A, the gently rounded part 21 of Figure 3 will be further elevated and thus emphasize the three-dimensional effect, as clearly shown in the completed article of Figure I.

Various effects can be secured on the deformable material A by producing the linear deformations with different types of tools 16. The illustrated tool has. a'

rather sharply rounded end 17 that produces a relatively sharp line on the material. More gently roundeddeformations can be secured with tools formed with end parts 17 of a larger radius. 7

The foregoing description of the formation of the article in Figure 1 relates to the use of :1V transparent. or frosted material A. In certain cases it maybe desirable to use opaque materials in which case the patterns B and C may be formed directly on each side thereof or transferred to the plastic just before the tooling operation. It is apparent that other methods of accomplishing the objects of this. invention may be used without departing from its scope.

The finished item is preferably mounted on a rigid The design part frame or backing to emphasize the three-dimensional attributes of the invention, and may also be provided with colored mats and backings. By way of example, Figure 4 shows the finished article 10 of' Figure l mounted on a still or rigid backing 23 by means. of staples or other fastening means 24. In the alternative the article 10 can be supported by a rigid frame and a semi-rigid backing. With the mounting shown in Fig; ure 4; all of the depressed parts of the design will lie in a plane with the periphery of the picture and thereby emphasize the depth efiects. For decorative purposes, particularly when the article 10 is formed of" a transparent or translucent material, the backing 23 may be of a colored material or painted or covered. with a colored paper.

Figure 5 illustrates the use of a peripheral border or' mat 25 overlying the finished design 10. The mat'm'ay of course be cut to conform to the outline of the design itself and may be of a rigid or semi rigid material or it may bepainted on the surface in any conventional manner. As an alternative the mat or painted border 25 may be placed on the underside of the design 10 as denoted by the numeral 25' of Figure 6.

With this invention a wide variety of artistic effects can be achieved by the proper'sele'ction of material's and the method of distorting the deformable material. For instance, the areas between adjacent lines of depression may be gently rounded or sharply pointed, substantial areas may be raised while other areas are depressed, or alternate lines may be raised while the ina V termediate lines are depressed. The versatility of the procedure, coupled with variations in the mounting means, and the wide selection of available materials, enable the production of many interesting designs and effects even by relatively untrained persons such as amateurs, hobbyists and children; and the required materials for effecting these results are particularly suitable for arrangement and sale kit form.

While only certain embodiments and modifications of this invention have been illustrated and described it is apparent that other changes and modifications can be made Without departing from the true scope and spirit thereof.
