PATENT arms BEATRICE P. SCOTT, OF MARBLEHEAD, MASSACHUSETTS REPRODUCING PROCESS Application filed August. 28, 1928. Serial No. 302,573.

This invention relates to a process for producing upon one surface, characters corresponding tolike characters upon another surface.

An object of this novel process coristitut ing the subj'ect'matter of thisinvention is primarily to afford amusement and entertainment for young and old.

AI further .object'is to provide means for.

-10 cheaply and rapidly transferring printed matter from paperto show windows, metal and other surfaces, so astoprovide ameans of advertising display which will neither damage the original nor the surface to which the copy is applied.

. A still further object is to provide means for transferring printed matter to other surfaces whereby the condition of the copy will be such that it may be readily erased or' made permanent at will, as desired.

. Other objects and advantages will be readily understood from the following description andthe accompanying drawing.

The drawing illustrates the apparatus of successive steps in the use thereof.

Fig. 1 is an exploded view of the apparatus-used in carrying out the invention and showing the first step in the process. 3 Fig. 2. shows the partscombined ready for the copying operation. I

' Fig. 3. illustrates thetransferring operation, while picture.

Referring in detail to the drawing, the apparatus used for practising the invention and shown in Figure '1 consists of a textile screen-like member 1, such as a piece of bolting cloth, muslin or the like. For con; venience in-use it is secured upon one side of a frame 2 preferabl rectangular in shape and made of wood. he bolting cloth'when 'attached makes, as it were, a hollow box, the wooden frame constituting the sides and ends, and the cloth the bottom of the box. Another frame 3 may be provided,which, however serves merely as a guiding or'limiting frame for retaining the-printed matter to be copied. This frame is not absolutely the invention'with the fingers showing the Fig. 4 shows the completed, transferred necessary but is a convenient means for preventing s'hifting of frame 1 during use. A piece of printed matter to' be'copied is in-- dicated by 4 and shown as a newspaper car- A toon or advertisement which it is desired to transfer to another surface. The printed matter may be cut to fit snugly within frame 3, or else the frame 3 may simply be set overthe newspaper or thelike so as to encompass desired portionsthereof. '1 '60 The first step in the process of reproduc-. 7 ing the character designated as 5 on the piece of newspaper 4 is to reproduce the. character on the bolting cloth. This step is carried out by placing the frame 2, bolting cloth. side down upon the newspaper, using the guide-frame 3 if desired, as illustrated in Fig. 2, and with a powder uif or piece of flannel represented as 6 ru hing a .lr powder over the upper surface of the clot within the box'. The powder may be cornstarch, talcum powder, or flour, for example.

The powder may be first dusted over the muslin or bolting cloth or it may be placed u'ponthe owder puff and then rubbed over the said c 0th.

In this rubbing, it has been found that the, .p ow der tends to adhere to that portion of the paper beneath the bolting cloth-which is defined by the printed char acter, but that no adherence occurs in the B0 unprinted parts. ltihas been found best to supplement the first rubbing with a' powder puff with a subsequent rubbing with a piece of chamois. This Very effectively rubs the powder into the interstices of the cloth Where it remains in those regions of the cloth above the unprinted part of the paper; but in the part of the cloth overlying the printed charactor, the powder has passed throughthe intersticesand adhered to the underlying print'ed character.

The frame 2 is then raised from the paper and when viewed by looking through the cloth it is found to contain a perfect reproduction of the printed character, the bolting cloth being rendered opaqueby the powder in'the meshes everywhere but in the region corresponding to the printed character. It will have the appearance indicated in Fig. 3. It

has been found that the powder is very effecwill also black or colored glazed paper, orthe f like. i

The image-bearing cloth is then placed 1 down upon this surface and while firmly held the ima e is reproduced upon the receiving surface by pulling a squeegee 15, a piece of rubber or card board over the cloth holding the design. The result can also be obtained by placing a piece of plain paper over thedesign and rubbing the paper.

This pulling or rubbing loosens and forces the powder from the bolting cloth upon the receiving surface, covering the surface except 5 for a region corresponding to the transparent part of the cloth and, of course, corresponding to the original printed character. Upon the removal of the cloth, the powder, which has been rubbed through, gives an outline defining a true representation of the original printed character. Y

The reproduction may be precisely like the original, if the original be black and white, by using a black glossy paper as suggested by 7 in Figures 3 and 4, or if on glass by painting with black paint the underneath surface of the glass. Various beautiful results may be had by using colored powders.

A squeegee hasv been mentioned as an impolished surface. It is not intended to limit the invention to any particular implement. It has been-found that the transference may be effected by merely drawing the end of the finger over the cloth. The squeegee is a con venient implement and is considered at present perhaps the best. The picture thus reproduced might be supposed to adhere so feebly that the glass or paper bearing the re production could not be handled except with great care. The adherence, however,-is so perfect, that the reproduction can be carelessly handled without danger of injury.

The imagemay be instantly removed by wiping the-surface with the hand or cloth, and the surface. is then ready for another transference.

The image may be made spraying with a thin coat of shellac and alco- -.hol or a suitable water soluble size.

The dry powder is of course chemically inert and no injur results even if the reproductions are ma e upon window lass or polished surfaces as of furniture by c ildren.

In addition to affording amusement when -may be selected such plement for reproducing the figures upon the permanentby used as described, the transfer device has a 1 value for advertising purposes. With such a process it will be seen that attractive advertisements, cartoons, or the like, may be readily reproduced by store-keepers or salesmen upon store windows or show-cases.

It will of course be. understood that f the charactersreproduced may bepictures, fig-, ures, letters or any printed matter. I have found that the best results are obtained by 75 working with u'nglazed newsprint paper,

rom any one printed portion of which a number of reproductions may be easily-made. This invention is not limited to the transference ofcharacters printedon newspaper. an Any material printed in printers ink may be copied. Image-carriers may be made by first printing the desired design on paper and then preparing the stencil as already described. This opens the way for originally producing R5 and thereafter reproducing a design.

Should it be desired to make such an imagebearing cloth permanent a suitable powder that when the imagepowder may .be hardenedby the use of a suitable liquid applied to the cloth. From such a permanent carrier many reproductions may be made.

\ A permanent image-carrier as described above will be particularly useful for advers tising purposes. It can be made more economically than similar carriers made by other methods. The reproductions may thenbe made in indefinite numbers with a-dry powder. Such reproductions can be easily rem0 moved by wiping the powder from the surface as hereinbefore described.

I claim: I

1. A process for reproducing characters formed of printers ink consisting in placing a screen over the characters to be reproduced, rubbing a dry powder into said screen to form in the interstices thereof a copy of the orig inal in powder-image form and thereafter carrier is formed the 00 placing said image-carrying screen upon a "from printers ink consisting in placing a. fine I mesh textile screen upon said characters,'rub- I25- bing'a fine powder over said screen and above the printed and unprinted region, again rubbing the powder into said screen with a chamois or the like, removing the screen from the printed surface and placing it over a receiving surface, and rubbing the powder remain ing in the screen with a squeegee or the like through the screen and upon the second surface.

4. A process of conditioning an image carrier adapted for transferring printers ink charactel's from one surface to another consistingin placing a fine mesh cloth over a surface containing said printers ink character and rubbing a dry powder over said cloth into the interstices of the cloth and throughout the region over the unprinted parts and through the cloth and upon the printed character in the region over the printed part.

5. A process for reproducing a character of printers ink consisting in placing a screen ,over the character, filling the interstices of the screenaround the outline of the character with a dry powder, placing the screen over a receiving surface and forcing the powder from the screen to that surface.
