5 Claims.

This invention relates to coloring implements g d aw wh ill s a preferred and the like and more particularly to paintingsticks, for coloring photographs, printed pictures and drawings, lantern slides, positive transpargencies-and the like. One of the primary objects of the invention is the provision of a stick or cartridge in various colors and of being impregnatedwith various .aniline dyes so that when dipped in wateror 10 moistened and applied to photographs or simi-.

lar articles it will leave a permanent impression The conventional method heretofore used for:

20 coloring photographs particularlythose having a glossy surface, usually requires a moistened brush. This brush is dipped in the color and then the photograph or similar article is painted in the usual manner.

.25 In view of the nonabsorbent quality of the bristles of the brush, however, it is exceedingly dlflicult to apply the coloring uniformly to the object in question, particularly .where glossy surfaces are concerned because of the tendency of 30 the water or moisture to form small pin-head drops onthe surface. On dull surfaces the moisture is inclined to flow or run and thus spoil the object to be colored. For this reason it has been necessary heretofore to use a sizing or 35 subject the object to be colored to a preparatory ghemical wash before application of color by the rush.

This difflculty has now been removed by the instant invention, which in terms of broad in- 40 clusion consists of a stick or similar object of fibrous material capable of absorbing moisture, impregnated with an aniline. dye which is soluble in water. Thus, the colorlngprocess may be eifectuated simply by dipping the stick inwater 5 and the release of moisture will be controlled by the degree of pressure applied on the color stick. Furthermore, the fibrous stick will absorb all the superfluous moisture released on the surface of the object to be colored. It is furthermore, the

5 object of this instant invention to impregnate the color stick with such a dye that it will penetrate a glossy surface and leave a permanent impression of color on the photograph.

The invention will be more readily understood as when taken in conjunction with the accompanyboiiiment of the inventive concept together with possible modifications thereof. In the drawing: Figure 1 is a front elevation of a crayon made of fibrous material according to the invention. Figure 2 is a section along the line 2--2 of Figure l.

Flgure 3 is a perspective view of a portion of the crayon made of rolled absorbent paper.

Figure 4 is a front elevation partly in section of a modification and Figure 5 is a view showing how the color is applied to the object. w

Now referring in more detail to the drawing, the stick generally indicated at l0 may be made of porous wood, paper, felt, pressed cotton, wool or any other fibrous material. The opposing halves I I and I! may be impregnated with differently colored dye so that they will produce a different color when moistened and applied to the object to be painted. This stick should preferably be provided with points l3 and H but may be provided as a square or rectangular tip.

A separating band or ribbon- 5 may be applied itself to the production of the implement according to the invention as shown in Figure 3. When porous or absorbent paper is used, it is preferably. rolled to form an elongated round stick.

The coloring implement may also be produced in the nature of a cartridge It as shown in Figure 4 of the drawing and inserted into a handle I! which may be provided with a reservoir It for the dye or water.

The aniline solution with which the improved color stick is impregnated is made by adding acetic to boiling water and then combine it with a suitable binder such as arabic gum, or dextrine.

In making the basic solution a gallon of water is first brought to a. boil and then about a tablespoon of acetic acid and one tablespoon binder,

such as arabic gum, is added. About one pint of this solution is then mixed with about one quarter pound of dye-of the desired color to produce the mixture, ,when the dye is dissolved in the one pint of the solution it is then poured back into the remainder of the original solution making about one gallon of the color needed. The

' fibrous sticks are then dipped into the solution.

until they are thoroughly and uniformly impregnated with the dye. It is perferable to impregnate the sticks while the mixture is still hot. After the solution is cooled it may be filtered and stored for future use. Formaldehyde can be added as a preservative.

The coloring implement thus produced will have a porous structure giving a very large absorbing surface for the dye which as stated is preferably an acetic solution of aniline dye of desired color.

The improved crayon may be used to apply coloring to photographs or similar articles simply by moistening it in water and then rubbing it gently over the surface. The acetic solution of aniline dye will penetrate the gelatin surface of the photograph and leave a permanent impression of color thereon. It will be observed that no portion of the stick is abraded during the rubbing operation upon the object to be colored and thus uniform blending can be assured. In the crayons heretofore used, which generally comprise powdered chalk, portions thereof wil be abraded on the surface which will leave spots of more intense color upon the surface of the object to be colored. The use of the improved absorbent crayon furthermore obviates the necessity of using a sizing compound and thus considerably facilitates and expediates the coloring process.

It will be understood that various changes, substitutions and modifications in the arrangement may be resorted to without departing from the spirit and scope of the invention.

What is claimed is:

1. A non-abrasive coloring implement for use in coloring photographs and the like, particularly those having a glossy surface, comprising a selfsustaining stick of fibrous material capable of absorbing moisture, said stick being impregnated with an aniline dye in absorbed condition soluble in water and capable of penetrating the glossy surface of the object to be colored, whereby said stick may be used in the manner of a painting brush simply by dipping it in water.

2..A non-abrasive coloring implement for use in coloring photographs and the like, particularly those having a glossy surface, comprising a self-sustaining stick of fibrous material capable of absorbing moisture, said stick being impregnated with a dye in absorbed condition soluble in water and capable of penetrating the glossy surface of the object to be colored, whereby said stick may be used in the manner of a painting brush simply by dipping it in water, said stick also being substantially resilient whereby the release of moisture and dye may be controlled by the degree of pressure applied thereto and whereby excessive moisture and dye may be absorbed.

3. A non-abrasive coloring implement for use in coloring photographs and the like, particularly those having a glossy surface, comprising a selfsustaining stick of fibrous material capable of absorbing moisture, said stick being impregnated with a dye in absorbed condition soluble in'water and capable of penetrating the glossy surface of the object to be colored, whereby said stick may be used in the manner of a painting brush simply by dipping it in water, and moisture-proof means capable of serving as ahandle partly enveloping said stick for maintaining said stick in a moistened condition whereby the same will be ready for immediate use without preliminary moistening.

4. A non-abrasive coloring implement for use in coloring photographs and the like, particularly those having a glossy surface, comprising a cylindrical applicator of unsized absorbent paper wound to form a self-sustaining substantially resilient stick capable of absorbing moisture, said stick being impregnated with a dye in absorbed condition soluble in water and capable of penetrating the glossy surface, whereby said stick may be used in the manner of a painting brush simply by dipping it in water and whereby the release of moisture may be controlled by the degree 01' pressure applied to said resilient stick.

5. A non-abrasive coloring implement for use in coloring photographs and the like, particularly those having a glossy surface, comprising a stick of fibrous material capable of absorbing moisture, said stick being impregnated with a dye in absorbed condition soluble in water and capable of penetrating the glossy surface of the object to be colored, whereby said stick may be used in the manner of a painting brush simply by dipping it in water.
