MEANS FOR `REPRODUCING DIAGRAMS DESIGNS AND THE LIKE 2 Sheets-Sheet 2 Filed July 15, 1943 Patented Apr. 12, 1949 MEANS FOR REPRODUCIN G DIAGRAMS, DESIGNS, ANDTHE LIKE William Swartz, Chicago, Ill., assignor to Embosograf Company of Illinois, a partnership Application July 15, 1943, Serial No. 494,882

The invention relates to the art of reproducing diagrams, designs and the like and is particularly concerned with a novel method of, and means for reproduction of designs, diagrams and in general any representation of ornamental or educational nature.

In the graphic arts the reproduction of designs or diagrams was hitherto carried out by producing a drawing of such design and thereafter a single die was produced which formed a replica of the desired design. In this method it is necessary to produce an individual die for each and every design entaillng a high cost and considerable time for producing such dies.

The present invention deals With the reproduction of designs and the like obviating the necessity of producing drawings to serve as patterns and obviating the necessity of making up unit dies especially of complicated and large diagrams.

It is one of the principal objects of the invention to provide a plurality of die sections or elements which can be assembled to form a single die dening the desired design or diagram and which segments can be re-arranged in many Ways to produce varieties of designs.

It is a further object of the invention to secure the die segments in assembled relation so as to obtain the same reproduction as if a unit die had been used.

Another object constitutes the provision of die segments which when assembled and brought to bear on the printing or engraving material under pressure leave an imprint of a continuous and uninterrupted nature the same as if a unitary die had been used.

It is also an object to provide certain features of lconstruction and assembly tending to enhance the utility and eliiciency of the invention.

With these and other objects in View which Will become apparent from a perusal of the invention, the latter comprises certain steps in a novel method and means for carrying out such method as described in the following specifications, particularly pointed out in the claims forming a part thereof, and illustrated in the drawings, in which:

Fig. 1 is a topplan view of a die segment constructed in accordance with my invention.

Fig. 11 shows a portion of the diagram in an enlarged scale.

Fig. 12 is an enlarged section on the line I2--I2 of Fig. 10. y

Fig. 13 is a fragmentary perspective view to illustrate a step in carrying out my process.

Fig. 14 is a perspective view of a special paper employed in the method, and

Fig. 15 is an enlarged section on the line I5-I5 of Fig. 13.

The invention is illustrated in connection with the reproduction of diagrams which is of course only indicative of the principle involved and may be applied to thereproduction of any representation where speed and inexpensiveness is of importance. The principle referred to involves the provision of die-elements or sections of various shapes or forms which may be assembled in any desired manner to assume a desired design and such assembled elements may be used as a unit for obtaining impressions to provide replica of such desired design.

The Word design is used to indicate any representation either of an ornamental, technical or educational nature.

Referring to the various views in the drawing. I0 designates a die-element which comprises a base II of rectangular cross section Which is integral with a synclined top or head I2 of less width at the base than the base II so as to de- Iine shoulders I3 and I4. The top face of the head I2 is grooved with angular side Walls to dene cutting edges I5 and I6.

Attention is called to the fact that in each element the head and the cutting edge are of the same length as the base so that when two die elements are placed endwise in abutting relation as shown in Fig. 10 at I'I, then the cutting edges are in contact, so that an impression made with these cutting edges is continuous and no break appears eventhough the die is not unitary but made up of elements.

Where elements are placed at right angles-to each other it is also necessary to have the cutting edge in contacting relation. To this end the dieelement I0 is cut away as at I8 and I9- so that the inner wall of the cut out portion or recess (Fig. 3) is in vertical registry respectively with the cutting edges I5 and I6. The die element 2| having cutting-edges 22 when arranged to lit with one end in the recess of element l0 provides for a contacting relation of its cutting edges 22 with the edge I6 of element IU. Thus again an impression made .withthese elements will show no break between the lilines Vproduced by'edges 2v2 and 16 Yand thus gives rise to the impression that a unitary die was used.

The angular element 23 has cutting edges "24 which extend the entire lengthof theelement.

The circular die element 25 is provided Jwith circular cutting edges 26, which are ush with the sides of the element.

The die-element 21 representing letter A shown in Fig. 9 has likewise cutting A'edges 28 ico-rterminous with the base of the element.

No attempt has been made to show all of the 4varieties of elements to be used and only a few *instanceshave been illustrated.

In.Fig. 10 anumber of elements are assembled to ,produce a diagram such as used to -denote `a radio circuit.

As indicated in Fig. 12 a lplatform 30 is placed on lthe `lower part of1apress l311 Vand a sheet of lchart paper 3l superposedby a layer 32 `of 'translucent waxis arranged on said platform.

On such layer 'of wax the elements are ar- .ranged to form thediagram shown in Fig. 1'0rand are "held in assembled relation by the wax the .squares of the chart paper aiding in arranging 'the elementsin proper position.

On-the assembled 'elementsis placed azsheet vof paper '33 `which on the .upper side is covered with a thermoplastic pressure-sensitive kadhesive s35.

The other side of the paper maybe covered ywith la y'layer -36 zinc 'sulphide 'or vrstrontium sulphide ywhich has luminescent properties. Over thepaper is 'arrangeda cardboard A3l. V'When the lowerpartf'34 of the press yis brought up'then the cutting edges of the die element will out out from vthe paper 33 strips forming a replica of the diagram shown in Fig. 10. The surplus paper -not used in lproducing the ydiagram is then re- `moved.

Thereupon the strips 'as shown in Fig. 13 are 'subjected to 'the influence of `an iron I38 whereby the adhesive is heated and cements vthe rstrips to the 'cardboard 31. y

'The paper 33 may be vof 'any desired Vcolor Yor design or many colors and where 'portions ofthe diagram uare `to 'have diierent colors, 'then additional `sheets or 'strips of paper 39 'may Vbe used in some portions ofthe diagram or design, as shown in Fig. 15. Theemployment Aof different colors vior portions of the design 4meets a long felt need since it enables the reproduction Yof Vcolor codes.

It is, of course, understood 'that the 4cutting edges of the-die elements are vin lthe `same'horizontal place so thateven cutting is ensured.

The invention has been s'hownto illustrate the principle underlying thesame.

Numerous changes and modifications may be made wit-houtdeparting from the spirit of the zinvention. I, therefore, do not limit vmyself to the sequence of steps enumerated 'in themethod,

nor to the particular construction of elementsv shown, but 'claim my invention as broadly as the :state ofthe zart ipermits,

I claim:

A1. .Adevice for reproducing designsand y:thelike `fromastripsfof -imaterial .comprising 'an rvassortment y of die elements of various shapes capable of being selectively assembled to simulate a desired design, each die element having spaced parallel forming edges capable of intimate contacts with the forming edges of an adjacent element, said elements being assembled end to end some of said elements being constructed to permit the *forming edge of an tangularly vdisposed element in abutting intimate relation to the forming edge .of the adjacent element and at angles to each other in conformity with a desired design, and

'means'.forautomatically holding said elements in lassembled relation during the stamping operation resulting in impression having Ia continuity of lines as produced by unitary dies.
