PRINTED S HEETS AND SPATULA FOR REPRODUCING DRAWINGS June 21, 1966 2 Sheets-Sheet 2 Filed July 21. 1965 #vvmvmm AFOAWEXY g 2 0 m 0 m4 JZ m United States Patent 1 Claim. (or. 35-26) This invention relates to a method and apparatus for producing an image, design or picture upon the surface of paper, fabric or the like. i

The principal object of the present invention is a method of transferring an image, design, picture or outline from a transparent sheet onto the surface of paper, fabric or the like by rubbing the back of the transparent sheet.

It is another object of the invention to provide a book having a supply of transparent sheets with images, designs, pictures and outlines thereon and a tool associated with the sheets for rubbing the images, designs, pictures and outlines oif of the transparent sheets onto the surface of paper, fabric or the like.

Another object of the invention is to provide a method of transferring an image, such as a line drawing onto a surface such as paper, fabric or the like by laying a transfer sheet of transparent material having the whole or part of the image printed in reverse on the underside thereof, ontothe' surface of paper, fabric or the like and then tracing over the obverse image visible through the printed sheet to transfer the image from the printed sheet onto the surface of the paper, fabric or the like.

Another object of the invention is to provide a method of transferring an image, such as a line drawing by laying a series of transfer sheets in turn onto the surface of paper, fabric or the like, each printed sheet having a separate part of the complete image printed in reverse on its respective printed sheet in a different color to the remaining parts of the image so that when the images are transferred in turn to the sheet of paper, fabric or the like, a complete multi-colored image is produced.

It is also an object of the invention to provide a method for transferring images, designs, pictures, outlines and the like from a transparent sheet onto the surface of paper, fabric or the like that is time saving, simple and easy to execute.

Still another object of the invention is to provide a method of transferring images, designs, pictures, outlines and the like from a transparent sheet onto the surface of paper, fabric or the like that is educational, instructive and interesting.

For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings and to the appended claim in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIGURE 1 is a top plan view of a loose leaf book, with transparent sheets having images thereon, the image on one sheet being shown right side up and the image on the other sheet being shown in reverse, made in accordance with the present invention, showing a tool in supported condition,

FIG. 2 is a top plan view of a fragment of a sheet with the tool shown in a position for using a flat end for rubbing purposes,

FIG. 3 is a similar View showing the tool disposed at a different angle to the sheet for using a knob formed on one long edge for rubbing purposes,

7 3,256,618 Patented June 21, 1966 FIG. 4 is a similar view showing the tool disposed at a slightly different angle from FIG. 3 so that the knob and one end corner may be used for rubbing purposes,

FIG. 5 is a similar view but showing the tool disposed to permit use of one of the round end corners for rubbing purposes,

FIG. 6 is a top plan view of one of the sheets of the book shown in FIG. 1, the image being displayed in reverse form, identifying indicia being shown associated with the image.

FIG. 7 is a perspective view of the same sheet in rightup condition with a sheet thereunder, showing the step of tracing with a spatula, the parts of the carbon impression'thereby transferring it to the surface as a stereotyped reproduction,

FIG. 8 is a similar view but showing the corner of the tracing sheet lifted to show the impression produced by the use of the spatula, and

FIG. 9 shows the tracing sheet completely removed and the outline of the impression on the surface of the blank sheet being traced over manually with a pencil.

Referring in detail to the drawings, in FIG. 1 a loose leaf sheet book is shown and designated generally by the reference number 10. The book 10 comprises a plurality of leaves or sheets 12 superimposed on each other and loosely joined to each other by the convolutions of a coil wire spring 14 extending loosely through holes 16 formed in the inner edges of the leaves or sheets. The leaves are adapted to be turned over very readily.

Each leaf 12 is formed of transparent sheet material such as tracing paper 13. The sheet must be sufficiently translucent to receive outlines on the surfaces permitting the outline which has already been applied to be seen, so

that the impressions carried by the sheet may coincide by superimposition.

Originally the paper or the drawing forming the sheet 18 has two identical faces 18A and 18B; face 18A being the view side, while face 18B is the reverse.

Starting from an original drawing or inscription, a stereotype effect results which may be regarded as a positive, that is to say that the words and figures are written in such a way that they may be read directly on the image of the photoengraving.

With this stereotype effect and by using a copying ink, face 18B of transparent sheet 18 is imprinted so that this sheet is converted into a printed sheet serving as a means for reproducing on any surface, for example, on a piece 20 which may be made of paper, cloth or any other suitable material, in fact, when this printed sheet showing a negative reverse image is transferred by tracing to another surface, the drawing copy is obtained as a positive.

The impression made with copying ink on the transfer or printed sheet as indicated in FIG. 7 may be one of one color only, or in a combination of several inks, by using stereotype positives of various colors.

The traces 22 are thin lines, as made by a pen, so that the negative imprinted image with copying ink, is destined to be integrally copied.

Thus, after applying the printed sheet 18 with its face 18B against a sheet of paper 20, employing, for example, a tool such as a spatula 26 with a central knob handle 29 (FIG. 7), the sheet is rubbed on the surface of face 18A, obtaining the transfer of the whole image which, with traces 28 is copied on the sheet 18B as shown in FIGS. 8 and 9.

The design impressed on paper 183 results in relatively feeble lines 28, therefore, it must be retouched with a pencil or pen 30 as shown in FIG. 9 reinforcing the traces with a purer line 32 so as to obtain a greater clearness in the image. Furthermore, this serves as a test for a student for example, in order to educate his hand in the art of drawing. Said reinforcement can be made with ink in black or in contrasting color.

As the carbon ink of the negative impression 22 maintains a certain load on the face 18B, the printing sheet 18 serves to copy several drawings, that is to say, the reverse side contains enough ink so as to execute the work of six or eight copies on sheets of paper 18B.

By copying ink is meant an ink which may be copied or transferred by the above described method.

In FIGS. 2 to 5, inclusive, various ways of using the spatula 26 to facilitate the rubbing operation are illustrated. In FIG. 2, the spatula is shown rubbing off the image with one of its straight ends; in FIG. 3 by means of the knob 29 that serves as a handle; in FIG. 4 by a two-point rubbing contact, the knob 29 and the angled corner at one end; and in FIG. 5 by one of the curved corners at one end of the body of the spatula.

The spatula is normally held between the convolutions of spring 14 and can readily be released by simply turning the body thereof to permit the knob 29 to slip through adjacent loops.

While we have illustrated and described the preferred embodiments of our invention, it is to be understood that we do not limit ourselves to the precise construction herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claim.

What is claimed is:

A device of the character described comprising an elongated helically coiled spring, a plurality of flexible transparent sheets each of which is provided with a row of equally spaced apertures along one edge thereof through which the convolutions of said spring extend to secure said plurality of sheets together into a loose leaf book, a pictorial design printed in reverse in copying ink on the under surface of each of said sheets with the obverse design being visible through the upper surface of each of said sheets, a tool for rubbing the upper surface of a printed sheet to thereby transfer the design printed on the under surface thereof onto a blank sheet disposed in contact with the under surface of a printed sheet, said tool being dey tachably secured to said spring when not in use; said tool comprising a spatula having a thin flat body defined by a pair of spaced parallel side edges and a pair of end edges by which adajcent ends of said side edges are connected together, at least one of said side edges and at least one of said end edges converging at an acute angle, with the connecting corners of said side edges and said end edges being curved, and a knob which is connected to one of said side edges by a short narrow neck section, said knob being adapted to be disposed within the convolutions of said spring with said neck section extending outwardly therefrom between two adjacent convolutions of said spring.
