Patented Aug. 24, 1937 UNITED STATES PATENT OFFIQE N Drawing. Application April 20, 1936, Serial No. 75,412

2 Claims.

My invention relates to a method of making drawings and cuts, and has for its principal object to produce a drawing or cut susceptible of varying shades in black or any other color, or

5 combination of colors, made preferably with pen or brush and ink, and in which the shade is made to appear just as the artist desires.

The predominant feature of my invention consists in applying to a surface of any conventional type of drawing paper, or a plate ultimately to form a cut, a film of adhesive coating which, when dry, is to be manipulated in such a way as to produce interstices on the entire surface of said film coating or such portions as may be desired,

and the application of ink to said coated surface with said interstices thereon, whereby said ink may pass through said interstices to the surface of the drawing paper or the plate, and if more ink is desirable to be applied, the further manipulation of said coated film surface to produce larger interstices and the application of more ink thereto, whereby a greater quantity of ink may reach the surface of the drawing paperor plate through said large-r interstices.

Another important feature of my invention is to produce a drawing or out made with ink and simulating a crayon drawing but not possessing any of the disadvantages of a crayon drawing, such as the tendency to smut or smear if 30 the hand be passed over and in contact with said drawing. Crayon also has a tendency to deposit on a toothed drawing paper more crayon on the side of the tooth in the line of advancement of the crayon and less, if any, crayon on 35 the opposite side of the tooth. The result of this is a dimness of outline and a possibility of the disturbance or displacement of the heavier crayon mass on the tooth or point in the paper, and the primary object of the present invention is 40 to produce a drawing or out having the characteristics of a crayon drawing with the tone qualities most desired in the drawing, and one which will reproduce readily from the cut ordinarily made from the drawing on paper.

45 In preparation for the drawing, I prepare a sheet of drawing paper of the conventional type and apply to one surface thereof an adhesive solution containing such a proportion of the adhesive as will leave a relatively thin film coating 50 of said adhesive upon the surface of the paper when the solution has dried. I spread this liquid adhesive solution upon the surface of the drawing paper by using a plate having a line of fine, shallow teeth on the spreading edge thereof. This 55 produces a coating of the solution of uniform thickness upon the paper. I then thoroughly dry the solution, preferably by use of a fan, and this evaporates the solvent in the adhesive substance. After the solution is dry, I securely hold the sheet of drawing paper in position on a flat surface, then I preferably take a straight edge for easy and simple manipulation and draw the same over the adhesive coating while said straight edge is in contact therewith. My experience has demonstrated that any method of disturbing the 0 coated film. surface will produce interstices therein. This manipulation divides the adhesive coating, or rather, breaks up said coating into interstices more or less minute and more or less uniform, and is relatively simple. 15

The above-described operation prepares the drawing surface for the first application of ink thereto. I now apply the ink to the adhesivecoated surface having the interstices therein to produce the desired drawing. I then thoroughly dry the ink. Then, securely holding the sheet of drawing paper in position on a flat surface,

I again manipulate the adhesive-coated surface of said drawing. This second manipulation of the surface of the adhesive film not only increases the size of the interstices, but produces some additional ones, and therefore more ink can be deposited on the surface of the drawing paper through said interstices.

I now again apply ink to the coated surface at the desired points, and as more ink can now be applied to the drawing surface of the paper through the still larger interstices, it will be seen that where ink has been applied after the second manipulation of the coated surface I have produced a deeper color because a larger quantity of ink has been deposited on the drawing surface of the paper through said larger interstices.

If a still deeper color be desired after the second application of ink has been thoroughly dried, I again manipulate the adhesive film coating, thereby again still further enlarging the interstices, after which I apply ink to that portion of the drawing which I wish to appear of still darker hue, and then allow the ink to dry thoroughly.

It will be understood that the ink is applied both to the adhesive coating and to the interstices therein each time that ink is applied to the drawing. If my drawing is now of the desired tone, I proceed to remove the adhesive film. coating by any appropriate eraser means, which removes not only the adhesive coating but the ink appearing on said coating as well, thus leaving only the drawing itself remaining on the surface of the drawing paper. Due to the fact that ink has been applied to the surface of the drawing paper only through the interstices in the adhesive film coating, a drawing is provided admirably suited for reproduction purposes.

While I have spoken of black ink, it is to be understood that I can employ any color of ink desired if the drawing requires color, and such color can be light, medium, or heavy as desired 10 to effect a particular shade or tone to suit the artist, depending on the number of times'the hereinbefore described operation is performed.

It will be understood that this same process" viously described, after which the plate is submitted to the usual acid or other appropriate treatment, the ink serving to protect those portions of the plate not to be affected by the subsequent treatment of said plate.

By my herein described method of producing drawings I can secure a drawing having the spatter effect admirably without any of the disadvantages usually found in producing spatter effect drawings, in that the spot of ink in such spatter effect drawings is sometimes so infinitesimal that it does not afford sufficient protection to the plate during the etching'process. I have found that by my herein described method of producing drawings I can get all of the desired 40 crayon effects without the uncertainty or dimness of outline characteristic of crayon drawings, as by my method a sharpness of outline is always present.

While I have described my invention in detail as above set forth as the best embodiment thereof, it should be understood that the dried adhesive coating can be disturbed so as to produce the desired interstices in many different ways, as, for instance, by passing the fingers over such portions thereof as I want the intersticesto appear on; or I can use any object other than a straightedge for such purpose, such as a stomp or brush, or the like.

I claim:

1. The herein described method of producing drawings and cuts which consists of uniformly applying to one surface thereof a film of adhesive coating, thoroughly drying the same, then disturbing the surface of said film of adhesive coating so as to produce interstices therein, applying ink to said coated surface, then thoroughly drying said ink, again disturbing the surface of said film of coating so as to produce larger interstices therein, again applying ink to said coated surface, then thoroughly drying said ink, and then removing said adhesive coating from said surface. v

2. The herein described method of producing drawings and cuts which consists of uniformly applying to one surface thereof a film of adhesive coating, thoroughly drying the same, then disturbing the surface of said film of adhesive coating so as to produce interstices therein, ap-

plying ink to said coated surface, then thorough- 1
