COMPOSITION FOR DRYING PAINTS AND OILS SPECIFICATION forming part of Reissued Letters Patent No. 10,039, dated February 21 1882 Origirial No. 211,928, dated February 4, 1879. Application for reissue filed November 10, 1880.

To all whom it may concern:

Be it known that I, ALFRED \V. PRATT, of Flushing, in the county of Queens, in the State ot'New York, have invented a certain new and useful Process for the Production of a'Oompositiontobe Used as a Drier for Paints, 0ils,&c., which is fully set forth in'thc following specification.

My invention consists of a process For the production of manganese-lead soap to be used as a drier for oils, paints, 850., as follows: I take caustic soda, dissolve the same in water insuch proportions as to make a strong lye.

Ithen put this lye into a receptacle with as.

much oil as itxvill saponifly and boil them until Then 1 mix a solution of chloride ot'inangancse or other manganese salts with an aqueous solution of some salt or salts of lcadsuch as acetate-and this solution 1 add to theplastic mass produced by the saponification ot the oil by the lye. The plastic mixture acts on the liquid mixture, thereby producing a manganese-lead soap. I then cleanse this resultant plastic mass (manganese-lead soap) with water and dry it, and

when so dried 1 add rosin or other resinous substances, and then heat the mixture in any suitable receptacle until it becomes a homogeneous mass, then remove the composi'ion from the receptacle and allow it to cool.

I obtain the best result by taking ten pounds of caustic soda, seven and a half gallons of oil,(linsecd preferred,) thirty-four pounds of rosin or other resinous substances, fourteen pounds ot'sonie salt of lead or salts of lead, and ten gallons of asolution of chloride of manga nese. I do not, however, confine myself to Y these exact proportions of the ingredients, as they may be varied considerably.

I prefer to use as an ingredient in this com- 40 tic soda, and instcadof chloride of manganese any salt of manganese may be substituted, and the saltsof manganese can be used without dissolving them in water.

A drier will be produced without the addi; tion of rosin or other resinous substances, although a better article is produced with using it. I prefer to use the chloride of manganese left as a residuum after heating black oxide of manganese in contact with muriatic acid, asin the ordinary process of manufacturing free chlorine. This manganeselcad soap may be used just as it is, or thinned or diluted by adding thirty-live gallons of oil, (for which turpentinc and naphtha may be partly or wholly substituted,) when the composition is ready for use as a liquid dricrfor facilitating the drying of paints and oils.

'hat I claim is- 1. The within-described process of produc- 'ing a manganese-lead soap by treating oil with caustic alkali,or its equivalent, and the resulting plastic mass with a mixture of manganese and lead salts, as described.

2. The within-described process of producing a manganese-lead soap by treating oil with caustic alkali or-its equivalent, and the resulting plastic mass with a liquid mixture of manganese chloride and lead salts, and adding thereto rosin or other resinous substances.

ALFRED \V. PRATT.
