My invention relates to a novel improvement in the art of making pictures and has special reference to an illuminated picture and the method' of making same.
The object of my invention is. to produce pictures which will have a pleasing appearance when illuminated by li ht thrown upon the outer surface thereof an will have even a more pleasing appearance when illumlnated from the back so that the pictures are seen by transmitted light.
A further object is to provide a method of producing pictures which will have pleaslng appearances both by reflected and by transmitted light.
The colors which I use in making my plctures are mainly what are known as anline colors, and one important feature of my-lnvention consists in the production of a peculiar base material for receiving the colors or paints in the production of the pictures.
In order to obtain the peculiarly beautiful effect which I desire I have found that it is necessary to prepare a translucent base with what I term a pebbly or Toughened surface presenting many small surfaces arranged at many angles one to another.
I have found that one practical method of producing the desired pebbly or roughened surface is to spray clear varnish upon a cloth of the proper kind. I have found that a fine grade of linen cloth is suitable for a base.
In reparing the `base I apply the clear 86 varnis to both sides or surfaces of the cloth, the cloth having first been stretched and secured to a suitable frame. I apply the clear varnish by means of an air spray and of such a consistence or fiuidity that l0 the exceedingly small drops of the varnish which are deposited upon the cloth retain` to some extent, their globular or rounded shape, particularly upon their outer surfaces, so that when the base is dried after the application of the varnish it presents what I term a/pebbly or roughened surface having many small surfaces which act to reflect light at many angles, and also which act as lenses to refract or turn the light in many direco tions.
After the varnish has been dried and hardened I apply the colors, to produce the plcture, to the varnished surfaces. I preferably apply the colors to the front surface of the base =by means of an air brush, that is, by spraylng the colors upon the surface, and
use aniline colors for this purpose, using the necessar colors and tints to bring out the result esired. I then proceed to develop or bring out the deeper shadows or darker parts of the picture by likewise spraying an' ine colors upon the rear surface of the base.
The aniline colors do not give the contrastl which is necessary to produce a picture for reflected li ht, or what may be termed a daylight picture. For this purpose I apply oil colors to the high light portions of the picture, or to those parts which it is necessary or desirable to cause to stand out more rominently. Having finished the applicatlon of the colors, as described, to produce the picture desired, I next apply a coat of clear varnish to the outer surface of the base over the whole surface thereof, and when this coat of varnish has dried to a sticky or tacky condition I apply to the surface prepared clear glass particles in the form of very small globules, or what are known as beads or dust coverin the surface completely and a layer of t ese glass particles adhere to the tacky varnish.
Having prepared the picture in the manner described, I mount it in a deep frame and arrange an incandescent electric lamp behind the picture in a position to best i1- luminate same from the rear. Certain pictures for this purpose are usually selected because they (present an ap earance particu-4 larly adapte for especial y bright illuminatlon in one part and from which point the whole picture has the appearance of being illuminated, such, for instance, as sunlighted or moonlighted land or water scapes.
In the accompanying drawings I have illustrated the product and the method of producing the product.
Fig. 1, is a front view of a picture made in accordance with my invention;
Fig. 2, is a horizontal section on the line 2-2 of Fi 1;
Fig. 3,;1s an enlarged fragmentary sec x Cil tion of the base or material upon which the icture is produced, showing the first step in the process and taken on the line 33 of Fig. 1;
Fig. 4, is a section similar to Fig. 3 and illustrating the neXt step after the application of the colors; and
Fig. 5, is a similar section after the application of the glass globules or beads.
In said drawings 1 is the linen or cloth base which is stretched upon an open frame 2, which in turn is adapted to be mounted in a relatively deep picture frame 3. Preferably, when finished, the frame 3 is closed at the back by'a closuie board 4..
In the rocess liereinbefore described varnish is rst sprayed upon both surfaces of the cloth. The varnish is indicated at 5 and has a pebbly or roiighened outer surface,
The next step is the application of tlie colors which is indicated at 6 on the front and 7 on the back. That on the back being for the purpose of accentuating the shadows or dee er parts of the' picture. These colors are a-niline colors. Then the high lights are brought out by the application of oil colors by hand to the parts necessary, as for instance, the red tile roofs, etc., and indicated at 8, Fig. 4. After the colors have been applied a coat of clear varnish 9 is applied to the front of the picture and when it has dried to a tacky or sticky condition small clear glass lobules, or glass dust, is applied to the varnish and a layer of these fine glass particles adheres to the varnish completely covering same, as shown at 10.
After the picture is competed it is mounted in the frame 3 and an electric lamp 11 is arranged behind the picture in the place which-will best bring out the picture, as for instance, behind the representation of the sun, as shown at 12, in Fig. 1.
As many modifications of iiiy invention will readily suggest themselves to one skilled in the art, I do not limit or confine my invention to the specific steps or order of steps, or to the specific product herein described and illustrated.
1. The method of making pictures which consists of spraying varnish upon a cloth base to produce a pebbly or roughened surface, applying translucent colors to said prepared surface to produce the picture desired, applying varnish over the colors, allowing the varnish to dry until it becomes tacky and applying fine sand-like particles of glass to the varnish, while in tacky condition, whereby the picture is given a permanent coatin of sai particles.
2. 'lille method of making pictures which consists in applying varnish to a cloth base in such a manner as to provide a pebbly surface, a plying aniline colors to the varnish to pro uce the picture desired, applying oil paints to the high lights of the picture, coating the picture with varnish and allowing it to dry until it becomes tacky, and while it is tacky applying transparent particles, such as glass, to provide a coating of such particles.
3. The method of making pictures which consists in applying clear varnish to bolli surfaces of a base consisting of a sheet of cloth, such as fine linen, applying translucent colors to one side of the base which is to be exposed to view to produce the general effect of the picture desired, applying similar colors to the opposite side to assist in producing the shadows or deeper parts of the picture, applying a coating of varnish to the exposed surface and permitting it to dry to a tacky condition and at such time applying a coating of relatively small transparent particles to the tacky varnish to provide a permanent coating of such particles.
4. The method of making pictures adapted to be illuminated either from the front or from the rear and which comprises, the application of a clear varnish to each surface of a base consisting of fine woven cloth. the application of translucent colors to the front surface to portray the picture desired, the application of similar colors to the rear surface to deepen the shadows of the picture, the application of oil colors to the front surface to heighten the high lights of the picture, coating the front surface with clear varnish, and when the varnish has dried suiiicient to be tacky the application thereto of a coating of fine clear glass particles.
5. The article of manufacture herein described, comprising a picture painted with translucent paint upon a base which has first been coated with varnish in such a man ner as to present a pebbly surface, and the exposed surface covered by a layer of fine glass particles secured by a coating of varnish applied over the paint.
6. The step in the herein described process of making translucent pictures, which consists in applying a clear varnish, to the surface of a picture foundation of fine woven cloth, in such a manner as to produce a pebbly surface when the varnish has dried.
'7. The method of' making pictures which consists in applying varnish to a cloth base in such a manner as to reduce a pebbly surface thereon and applying paint to said pebbly surface to produce the picture desired.
8. The method of making pictures which consists in applying varnish to a cloth base in such a manner as to produce a ebbly surface, a plying paints to said pebbly surface to pro uce the picture desired. and covering the paint coating with a coating of varnish.
9. A picture adapted to be illuminated from the rear and also to present a pleasing appearance when illuminated wholly from the front and comprising, a line woven cloth base coated front and back with varnish with clear varnish over the paints, and a which presents a pebbly o1' rough outer surlayer of small clear glass particles covering l0 face, a picture portrayed on the exposed surthe exposed surface and secured by the last face by aniline colors, the deeper arts or mentioned coat of varnish.
5 shadows brought out by aniline co ors ap- In testimony whereof, I have hereunto set plied to the back, the high lights brought my hand, this 7th day of October, 1925. out by the application of o1l colors to the exposed surface, the exposed surface coated JOHN CHITRLA.
