To all whom it may concern:

Be it known that we, JOHN T. Hoes and ROBERT D. SCHULTZ, of Zanesville, in the county of Muskingum and State oi Uhio, have invented certain new and useful improvements in Soap; and we do hereby declare the following to be a full, clear, and exact description of the invention, such will enable others skilled in the art to which it pertains to maize and use it,

Our invention relates to the nianutacturc oi bar-soap, and consists in the addition or compounding of indigo with any soap, preferably, however, with that grade or class of soups known to the trade as family or laundry soaps.

By the addition or compound of indigo, as

abovm nent'ioncd,not only"areiuiparted' to the soap the peculiar virtues of indigo, but also are imparted thereto the iollowing novel and peculiar properties and characteristics: For instance, if indigo be mixed or compounded with yellow-colored soap, the product will be a soap which, after a slight expo sure, will become of a peculiar green color. If cut or fractured, the interior of the cake will be found to be yellowish in color, and this 4 in g of indigo with scope of difi'erenteolors a variety of shades and colors of soaps may be made, possessing the peculiar qualities as described in the case of the green soap above mentioned.

The advantages of our invention are, first, an increased virtue of the soap itself by the addition to its detersive qualities of the peculiar properties of indigo, whereby is obviated the necessity of any separate or inde pendent use of ipdigo for laundry purposes;

"pc1fum'es,or other substances--siich 4 this maybe done withoutdeparting from i second, the peculiar green, blue, or other e I. is imparted to the soap without the additl. of any poisonous, injurious, or destruc" coloring matter; third, the peculiar-color r the soap imparted by the addition of ind cannot be imitated or otherwise obtained w out the addition of deleterious matter; an moreover, this peculiarity of color sci as a brand or distinguishing cbaracteir by which soap made afterthis manner in be recognized in the market from any 9th? fourth, the peculiar property of the soap cutting or fracturing, of changing by 0 tion from a color resembling the soap l the addition of indigo, to a color result, from its compound with indigo.

It is found that by the addition of bane this property of changing colo, above described, may be destroyed, while the same time a uniform color is fixed throughout the entire cake or mass;

Although we consider it desirable destroy this property. oi changing col-or, above described, nevertheless,
