IMPROVEMENT 11v THE MANUFACTURE-bewar The Schedule referred to in these Letters Patent and making partof the same.

To all whom. it may concern Be it known that I, HENRY A; PnAsn, of -Hartford, county of Hartford, and State of Connecticut, have invented a new and useful Improvement in the Manufacture of Soap; and Ideclare the-ibllo'wing to be a full and exact description thereof.

My improvement relates to the manufacture of hard soap, as contradistinguished from soft orliquid soap.

The process is asfollows:

Take, say, seventy-five (7 5) pounds of tallow, stearine, or lard-oil, pour it into a kettle, and heat to about one hundred (100) degrees centigrade; a variation of a degree or two will do no hurt; 'Add one (1) pound of borax, skim ed the scum which soon rises, and allow to cool. When cooled to about ninety (90) degrees, (Centigrade always,) having providedone hundred and thirty-five (135) pounds of caustic soda-lye, of twenty-one (21) degrees strength, add the lye slow- 1y, till the mixture thickens. Care must be taken to have the lye cold, and of the right strength. When the lye is all in, stir rapidly till all the constituents are thoroughly mingled. When this is done, having provided tweuty-five (25) pounds of cocoa or other heavy vegetable oil, add the cocoa or other oil, which will tend to neutralize the lye. When the mixtute becomes free from a sharp bite, when applied to the tongue, then heat until the wholeis transparent, glossy, and Without spots. Now put it, expeditiously, into moulds or forms, and allow to harden.

Having proceeded thus far, I have produced a soap which is perfect, in its way, and which is vendible; but as I still further refine the soap, and produce a stillfiner article, I will, for convenience sake, desighate the process already described, as'the preliminary process, and the soap already produced, as the preliminary product.

g I will now describe how I further refine my soap.. Take the preliminary product, when it is cold and hard, and reduce it to powder. Put the powder into a kettle and heat slowly. For every pound of pow- .der, provide one (1) pint of gin, or other spirituous liquor, (preferably gin,) and commence puttiug'into the kettle, after the powder is-in, beating up the mixture as you pour, for it will froth. As soon as the powder melts. or liquefies, it will at once become solid. Add the gin or other li uor gradually, with care, for the mixture will rise in the kettle. The mixture will soon gloss over on the surface. Continue to f 7 add the liquor till all in. Themheat till the. whole forms a beautiful, transparent, jelly like mass N ow, add to every twenty (20) pounds of soap, seven (7) ounces of some peifumiugessence, or its equivalent of essential oil, for perfumery, and stir till thoroughly mixed. Then put into form expeditiously, stir till it begins to harden, and then cover up. v

The product, designated herein as p the final product, produced-by this last process, called herein the final process, is an excellent article for the toilet or medical uses. v

I claim, as my invention 1. The combination of ingredients described, forming the composition" designated herein as the pre liminary product,? thesame being compounded together by the process described herein as the preliminary process.

2. As an article of manufacture, the compounddesignated herein as the preliminary product.

3. The combination of ingredients, described herein, forming the compound designated herein as the final product, the same being compounded together by the process described herein as the final process.

4. As an article of manufacture, the compound described herein as the final product.

Dated May'2l, 1869.
