UNITED STATES ATENT FFICE.
HENRY SAWVYER, OF CHELSEA, MASSACHUSETTS.
GRANULATED LAUNDRY-BLUING.
SPECIFICATION forming part of Letters Patent No. 236,634, dated January 11, 1881.
Application filed October 3, 1878.
To all whom it may concern.-
Be it known that I, HENRY SAWYER, of Chelsea, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Laundry-Bluing, of which the following is a specification.
The invention relates to an improvement in laundry-bluing; and it consists in reducing the bluing or indigo to a granulated form, instead of pulverizing it, as heretofore, the object being to furnish an article which can be readily poured from a bottle or box of small size, and which will not deface, when dry, objects with which it may come in contact.
Heretofore it has been customary to grind the bluing or indigo until it was reduced to averyfine powder, and then place itin boxes or packages for the market. In this state the nature of the particles of the powder is such that they hold together in the box and cannot be readily poured out. Besides this, the powdered material attaches itself to any article with which it may come in contact, thereby very often causing injury and inconvenience. These two defects are overcome by the present invention, which consists in simply reducing the bluing or indigo to a granulated form, the grains or particles being made about the size of the grains of ordinary rifle-powder. This is the size which I prefer; but I do not limit myself to any particular size.
The reduction of the bluing may be accomplished in any convenient manner, but will probably be efiected by grinding more readily than in any other way. In the present instance I take the crude lumps of indigo or bluing, and pass them between rollers which are adjusted with relation to the size of the grains to be produced. The proper adjustment of the rollers can readily be accomplished by preliminary experiments. The bluing, after it has been crushed by passing through the rollers, is sifted, the meshes of the sieve being of such size that they will only permit the escape of such particles as have been reduced to a powdered form, all larger or granulated particles being retained within the sieve.
It is obvious that by a proper graduation of the size of the meshes of the sieve and of the adjustment of the rollers the bluing may be reduced to grains of any size desired. The lumps of indigo or bluing will all, at least, be reduced to a granulated form by ihe action of the rollers, and the sifting process is to remove all the finer or powdered particles, while such as are of the proper size will remain in the sieve, and are then ready for the market.
What I claim as my invention, and desire to secure by Letters Patent, is-- The improved laundry-bluing herein described, which consists of bluing or indigo reduced to a granulated form, substantially as set forth.
In testimony that I claim the foregoing improvement in laundry-bluing, as above described,Ihave hereunto set my hand this 30th day of September, 1878.
HENRY SAWYER.
