WILLIAM B. BRITTINGHAM, on NEW YORK, Y.
BLEACHlN G COMPOUND.
SPECIFICATICN forming part of Letters Patent No. 480,554, dated August 9', 1892. Application filed April-27, 1892. Serial ITO-430.889. (No specimens.) Patented in Belgium May 11, 1892, No. 76,804.
To all whom it 1m concern.-
Be it known that I, WILLIAM BAYNUM BRIT- TINGHAM, a citizen of the United States, residing in the city, county, and State of New York, have invented and produced a newComposition to wit, a Bleaching Compound, (for which I have obtained Letters Patent in Belgium, hearing date May 11, 1892, and numbered 75,304)0f which the following is a specification.
My invention relates to the employment of tu'ngstate of potassa of soda or the tungstate of any other alkali, together with hypochlorite of lime (bleaching-powder) andwater.
My invention relates, broadly, to the employment and utilization of tungstate of soda,
potassa, or any other alkali adapted to be em-' ployed in the manner hereinafter indicated; but in carrying my invention into effect, although I may employ tungstate of soda or potassa or the tungstate of any other suitable alkali, I prefer tungstate of soda, and,
will speak of tungstate of soda specifically, although I wish it to be understood that I do not limit myself in this respect, but may employ tungstic acid in combination with any other alkali. It is well-known that in the ordinary process of bleaching several steps are necessary in order to render-the fabric'pure and white, so that it can take a color. For example, in order to remove the gummy substances the goods are ordinarily submitted first to 2. liming process, after which they'are boiled under pressure. Then they are subjected to a scouring in order to remove the lime and then washed in water in order to re nove the acid, and finally passed through me hypochlorite solution.
In carrying my invention into effect I take a pint of water and mix therewith half an ounce of tungstate of soda, and in this solution I immerse the fabrics to be treated, having previously washed the goods in a manner similar to the washing employed in other bleaching processes, leavingthe goods in the above solution for five, ten, or fifteen minutes, according tothe nature of the fabrics.\ They can remain in longer, if desired, and while so immersed are agitated. At the proper moment I add to this solution and while the fabrics are still immersed hypochlorite of lime -or hypochlorite of soda.(the ordinary bleachers of commerce) in the following proportion, to wit rhalf a pound to four gallons of water. The whole is then stirred,
and the operation is eom'pleted in a .period of time varying from ten minutes to an hour. Upon the introduction of the hypochlorite the chlorine will be immediately set free in large quantities, and at the end of the time named the fabrics will be entirely bleached. When adding the hypochlorite of lime 0F soda to'the mixture, the resultant solution maybe heated, as the operation is'carried into efiect much better under a high temperature than under a low; but the heat is not absolutely necessary, and the'entire process may be carried on with coldwater. Tung-' stic acid dissolvesbut slightly in water; but
in combination with soda and chlorine the A bleaching compound consisting of the tungstate of an alkali combined with ahypo-- chlorite.
