UNITED STATES WILLIAM P. ARNOLD, OF NEW YORK, N. Y.
IMPROVEMENT IN THE MANUFACTURE QF PAPER STOCK.
Specification forming part of Letters Patent No. 130,462, dated August 13, 1872.
Be it known that I, WILLIAM F. ARNOLD, of the city of New York, in the State of New York, have invented a certain new and useful Process for the Manufacture of Paper Stock from the Reed-(Jane and other fibrous vegetable substances, disintegrated by the explosive force of steam, of which the following is a specification The reed-cane and other vegetable fibrous substances disintegrated by the process for which a patent was granted by the United States to A. S. Lyman August 3, 1858, is available as paper-stock; but in consequence of the great degree of heat to which the reedcane or other vegetable fibrous substance is subjected in that process of disintegration, it is dry, and somewhat harsh and brittle.
I have discovered a new, efficient, and economical remedy for the defects peculiar to this fiber, which consists in boiling it with saponaceous matter. Such boiling may be for a short time only, even less than an hour, and it may be in an ordinary boiling-tub withoutsteampressure. By this process the acid, resinous,
gummy, and coloring matters are liberated, and the fiber is cleansed and softened. Heretofore the said fiber has been boiled with lime and soda-ash or caustic alkali to break down and cleanse the fiber and make it available as paper stock. When lime is used it hardens the fiber and fixes the color in it. The sodaash and caustic alkali are costly, and it is necessary to thoroughly wash the same out when the paper to be made is to be sized,
which washing occasions a considerable loss quantity of saponaceous matter may be used, and a longer or shorter time of boiling, either in an open vessel or in a closed vessel, under pressure, may be given 5 but the effect is improved by increasing the quantity of saponaceous matter and lengthening the time of the boiling. The fiber thus prepared, being sufficiently purged of acid, resinous, gummy, and coloring matter, is ready for many usesfor example, to mix with straw, old papers, and other fibrous materials, to make binders-boards, box-board, and papeni'eltv It is also in a proper condition to be subjected to the action of caustic alkali in close boilers, to make pulp for the higher grades of paper. The abovementioned treatment of the said fiber is not available with or for any other materials-for example, it would be useless to subject straw to an hours boiling with a weak solution of soap in an open vessel.
The principal object of my invention and improvement is to avoid the necessity of washing the said fiber after the boiling thereof, which washing is necessary when sized sheathing felt or paper is to be made from the said fiber, and the said fiber has been boiled with lime or caustic alkali, which, if left in the pulp, would destroy the size, but which washing is unnecessary when the said fiber has been treated by the method or process above described. By thus avoiding the washing of the fiber there is a saving of from ten to twenty per cent. of the fiber, which saving is very important if not absolutely essential in the last-mentioned manufacture. Moreover, the fiber works up better, and time is saved by avoiding the washing.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. The abovedescribed process for the manufacture of paper stock from the reedcane and other fibrous vegetable substances disintegrated by the explosive force of steam, as aforesaid, by boiling the same with saponaceous matter, substantially as above described.
2. The. improved article of manufacture, consisting of the paper stock made by the process herein described.
