UNITED STATES CECIL PULESTON WOODS, OF BANG-OR, IRELAND.

REPRODUCTION OF DESIGNS, DRAWINGS, AND THE LIKE.

Application filed May 3, 1924, Serial No. 710,938, and in Great Britain May 4, 1923.

This invention relates to the reproduction or designs, drawings,letters, or characters etc, on paper, or other material so as to facilitate the production of designs for weaving, for example, or for the purpose of reproducing or transmitting .designs, pictures, lettters, or characters, or the like, by telegraphy.

Under my invention, the drawing, picture, design, letter or character, is reproduced by a device which consists of a plurality of rectangular or other shaped boxes adjoining one another, after the manner of a honeycomb, the top of the device being covered by a sheet having a corresponding number of holes and so arranged that the holes coincide with the boxes, and the other side of the device has a sheet of suitable material placed against it. The drawing, or design, or the like, is placed on the top of the sheet having the holes therein, the drawing, or design, being on transparent or semi-transparent paper, or other material, so that, when the drawing, or design, is placed over the holes then the holes covered by the design will not be acted on by light, which, acting through the uncovered holes, causes the squares or other shapes corresponding to the exposed holes to be acted on by the light and so reproduces, on the unexposed portions the picture, or design, after the manner of the artist or designer when drawing or painting on squared paper.

A sensitized squared sheet, such as photographic paper, placed against the other side of the device from the side having the sheet with the holes therein will reproduce the picture or design over the required number of squares on the paper.

The sensitized sheet may be such as could be used in known manner to electrically reproduce from the squares or other marks thereon an exactly similar picture or de sign, by producing, on the exposed portions, 2. surface whereon electrical contact is possible whilst the unexposed portions forming the design are given a non-conducting surface, or vice versa.

Drawings, pictures, or designs, could be reproduced to an enlarged or reduced scale on the sensitized paper at the back of the device by projecting same, by suitable known means, on the perforated paper, or equivalent, at the front of the device.

The artist, or designer, in preparing his drawing, or picture, or design, could draw on semi-transparent paper secured on a surface having dots upon it, corresponding to the holes in the sheet on the top of the device and the artist could draw his picture or design, so as to avoid or cover the dots and then fill in the drawing or design with opaque pigment.

By the use of suitably marked sheets, the artist or designer, could, when preparing his drawing, or design, have before him the positions of the squares for particular types of twilling in connection with designs used for weaving. Jacquard card cutters could read the cards directly off the projected reroductions of the design as shown on the suitably held up in front of him. '1he invention will be described with reference to the accompanying drawings which are diagrammatic and not to scale.

Fig. 1 is an isometric view of a portion of the device with design in position for reproduction on the squared glass plate, or

mper.

Fig. 2 shows a small portion of the device with the plate or paper thereon having small holes or perforations.

Fig. 3 shows a small portion of theunderside or the device and the effect produced on. some of the squares when the correspond ing holes on the top are covered by the design.

Fig. 4: shows the efi'ect produced when the design of leaf shown at Fig. 1 is reproduced through the squares on the squared sensitized paper.

Referring to the drawings The drawing, picture, or design 1 is reproduced by a device which consists of a plurality of rectangular, or other shaped boxes 2 adjoining one another, after the manner of a honeycomb, the top of the device being Covered by a sheet 3 having a corresponding number of holes 4, so arranged that the holes 4- coincide with the centres of the boxes 2. The other side of the device has a sheet 5 of suitable material placed against it. The drawing, or design, or the like, 1 is made on a transparent sheet or semitransparent sheet 1 placed on the top of the sheet 3 having the holes therein, so that, the holes 1 covered by the design 1 will not be acted on by light, which, acting through the uncovered holes et Fig. 1 causes the squares 2 corresponding to the exposed holes to be acted on by the light and so reproduce, on the unexposed t at the back of the squares, the sheet portions, the picture or design 6 as shown in Fig. 4-, after the manner of the artist or designer when drawing and painting on squared paper.

The sheet 5 may be a sensitized squared sheet such as photographic paper, placed against the underside of the device so as to reproduce the picture or design over the required number of squares on the paper. The number of squares to the inch would, for weaving purposes, vary with the counts or shots of the material to be woven in the loom.

The sensitized sheet 5 may be such as could be used, in known manner, to electrically reproduce from the squares, or other marks thereon, an exactly similar picture or design, by producing on the exposed portions a surface whereon electrical contact is possible whilst the unexposed portions give a non-conducting surface or vice versa.

Drawings, pictures, or designs, could be reproduced to an enlarged, or reduced, scale on the sensitized paper, or on the screen, or glass sheet, at the back of the device by projecting same by suitable known means on the perforated paper, or equivalent, at the front of the device.

The artist or designer in preparing his drawing, or picture, or design, could draw same on semi-transparent paper secured on a surface having dots upon it, corresponding to the holes in the sheet on the top or the device and the artist could draw his pictures, or design, so as to avoid or cover the dots and then fill in the drawing or design with opaque pigment.

By the use of suitably marked sheets, the artist or designer could, when preparing his drawing, or design for weaving, have before him the positions of the squares for par ticular types of twilling in connection with designs used for weaving. Jacquard card cutters could read the cards directly off the pro ected reproductions of the design as shown on the glass sheet or other suitable screen at the back of the squares, the sheet being suitably held up in front of him.

Having now fully described my invention what I claim and desire to secure by Letters Patent is l. A, device for reproducing drawings, pictures, designs, letters, characters or the like, consisting of a plurality of boxes arranged to form a cellular or honey-comb structure, a perforated sheet adapted to cover one side of the device so that said per forations will coincide with the boxes, a sheet of transparent material having a design thereon adapted to be laid on said perferated sheet, and a sheet of sensitized material adapted to be placed againstthe other side of the device.

A device for reproducing drawings, pictures, designs, letters, characters or the like, consisting of a plurality of rectangular boxes arranged to form a cellular or honeycomb structure, a perforated sheet arranged to cover one side of the device so that said perforations will coincide with the boxes, a sheet of transparent material having a design thereon adapted to be laid on said perforated sheet, and a sheet of sensitized material adapted to be placed against the other side of the device.

3. A device for reproducing drawings, pictures, designs, letters, characters or the like, consisting of a plurality of rectangular boxes arranged to form a cellular or honeycomb structure, a perforated sheet arranged to cover the top of the device so that said perforations will coincide with the boxes, a sheet of transparent material Having a degn thereon adapted to be laid on said perforated sheet, and a sheet of sensitized material adapted to be placed against the bottom of the device.

In testimony whereof I aflix my signature.
