SPECIFICATION forming part of Letters Patent No. 471,191, dated March 22, 1892.

Application filed March 27, 1891. Serial No. 886,674. (No model.)

T at whom it may concern.-

Be it known that I, WILLIAM Q. PREWITT, a citizen of the United States, residing at Lexington, county of Fayette, State of Kentucky, have invented a certain new and useful Improvement in a Combination-Crayon;

. and I declare the following to be afull, clear,

and exact description of the invention, such as will enable Others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, which forms a part of this specification.

My invention relates to certain new and useful improvements in a combinationcrayon; and it consists of the article of manufacture hereinafter described and claimed, and illustrated in the accompanying drawing, which is a View in perspective.

For many purposes it is found desirable to have in a single compact article of manufacture a crayon formed of a series of different-colored crayons, strata, or layers to produce a mark of striped appearance, the different colors of the stripe preferably being sharply defined at their adjacent edges to give a better effect. Such an article of manufacture for lettering in advertising-matter,

blackboard-work, and various ornamental uses will obviously have great advantages and desirability, producing a pleasing effect otherwise impossible to secure by separate crayons of different colors. A compound crayon of red, white, and blue colors united in one crayon, for example, could be used to strike off the stripes of our flag with perfect uniformity and effect. To this end, as shown in the drawing, a crayon A is formed with a series of layers a a a a, united at their edges. The stratum a, for example, may be of blue crayon. An additional stratum a, which may be of red crayon, is united to the blue crayon. Another stratum, as a which may be of yellow crayon, is united to the red. Another stratum, as a which may be of green crayon, is united to the yellow, and so on. These strata or layers of different-colored crayons are united permanently on their adjacent lateral faces, as shown, to form one integral crayon. This union of the differentcolored crayons or strata to form the one integral article of manufacture may be accomplished in any suitable manner within the scope of my invention. Thus, for instance, the different-colored strata or crayons of the series may be attached by a suitable adhercut material, as cement; or, instead, an 1ntegral article of manufacture may be formed in the process of manufacture by means of a series of communicating molds, in which a stratum or crayon of one color is first formed 6c in one mold, then when the first is in proper condition adding in the adjacent mold the plastic material of which the crayons are formed of a different color, which in setting will integrally adhere to the first, then repeating the process of filling each successive mold one after another when the previous stratum has sufficiently set or hardened to prevent the commingling of the colors, and so on for the series. In this manner strata of dif- 7o ferent colors may be made each of any desired thickness.

I do not confine myself to any specific form or shape of constructing my improved article of manufacture, nor do I confine myself solely to any particular material or materials from which to form said article of manufacture. Thus, for instance, for certain purposes the crayon may be formed of the materials commonly employed in the manufacture of blackboard-crayons and carpenters chalk, or for other purposes, as for marking on glass,

a soapy construction may be employed.

WVhat I claim as my invention is' 1. As an article of manufacture, a combination-crayon formed of two or more strata or layers of different colors, said strata or layers having their adjacent faces permanently adhered one to the other, substantially as set forth.

2. As an article of manufacture, a combination-crayon formed of two or more strata or layers of dilferent colors, said strata or layers having their adjacent faces permanently adhered the one to the other inthe setting of the plastic materials of which the strata or layers are composed, forming a single integral crayon, substantially as set forth.

In testimony whereof I sign this specification in the presence of two witnesses.

WILLIAM Q. PREWITT.

N. S. WRIGHT, JOHN F. MILLER.
