LAWRENCE REID, OF NEW YORK, AND JOHN ROGERS, OF BROOKLYN, N. Y.

IMPROVED SOAP.

Specification forming part of Letters Patent No. 44,457, dated September 27, 1864.

To all whom it may concern:

Be it known that we, LAWRENCE REID, of the city, county, and State of New York, and JOHN-ROGERS, of Brooklyn, King county, and State of New York, have invented a new and useful Composition and Mode of Preparing Soap; and we do hereby declare that the within is a full and exact description of the same.

Though diflerent proportions maybe used to the taste of customers, and to accommodate the manufacturers in the raw materials from which they prepare soaps, we will here state the mode of preparing our compositions and the proportions which we prefer.

Having our soapprepared from good raw materials-as fat, caustic soda lye, a little palmoil, and all well boiled and saponitied in salt and alkaline lyes-it is retained by heat in the fluid form and fit to mold. We then prepare our solution of glue or gelatine, either as weobtain it in making bone-glue or skin-glue or gelatine from any source, or by the solution of glue or gelatine in hot water at the boilingpoint, or very near it-say for every hundred pounds of melted hot soap take six pounds of good glue or a solution of gelatine or glue, as before described, equivalent to that proportion of dry glue, all being in a hot state, near 212 and perfectly fluid. Mix both together and add at the same time three pounds of causticsoda lye of the'strength of twenty-five per cent. by Baums hydrometer, this last also near the boiling temperature. Continue to mix, and immediately mold, or, better, to suit the custom of soap-makers, the mixture may be made in the usual mold, taking the same precautions in regard to a thorough and complete incorporation of the difl'erent materials, and that they be all at the boiling temperature or near it previous to mixing. Though we have named these proportions as making a powerful, elegant, and useful family soap, it \vill'be obvious to soapmakers that they may be much varied, increasing the productand intensifying the quality of soap by the relative quantity of glue or gelatine and caustic soda'employed from twenty-four to cent per cent. In the quantities used, as above described, the increase in weight is twenty-four per cent.

What we claim as our invention, and desire to secure by Letters Patent, is-

lheincorporatingofgelatineorglue as made previous to drying in a fresh state, or a solution from the dry articles in suflicient quantity, as from five to fifteen per cent. of glue, and a proportion of caustic soda by from three to nine per cent. of the specific gravity of 25 by Banms hydrometer, the whole forming a uniform mass, possessing the treble attraction of gelatine, caustic soda, and ordinary soap for dirt, and thus increasing quantity and improving quality, all donein the manner set forth in this specification.
