UNITED STATES PATENT OFFIoE.
CORNELIUS T. TOMKINS, or NEWARK, NEW JERSEY.
K lMPROV EMEN-T lN PROCESSES OF MANUFACTURING PAPER.
Specification forming part 'of Letters Patent No. 222,430, dated December 9, 1879; application filed b May 15, 1879. v
To all whom it may concern:
Be it known that I, CORNELIUS T. TOMKINS,
of Newark, in the county of Essex and State of New Jersey, have invented a certain new and useful Improvement inthe Processes of Manufacturing Paper; and I dohereby declare the following to be a description thereof in such full, clear, and exact terms as to enable any one skilled in the arts to which it appertains or with which it is most nearly connected to practice the same. 4
The object of my invention is to improve the .1 quality and cheapen the production of paper. i 1 The invention is confined to the preparation of the pulp of which thepaper is to be made;
and it consists of combining with it or adding to it acicular crystallized sulphate of lime, possessing the quality of felting or matting with the fiber of the pulp in the manufacture of the paper;
improved method of treating gypsum, dated July 15,1879,No. 8,803, to which reference is made for a more perfect understanding of the method of preparing or making the acicular crystallized sulphate of lime.
The practice of this invention. is accomplished by merely adding to, or combining with, the fibrous paper-pulp, in any convenient and efiectual way, the acicular crystallized sulphate of lime, which can be readily obtained by the treatment of dehydrated gypsum, substantially as described'in the patents aforesaid, or by treating artificially-made sulphate of lime substantially in the same way.
Having thus described my improvement in the process of manufacturing paper, I claim and desire to secure by Letters Patent-'- Combining acicular crystallized sulphate of .lime, possessing a felting property, with the fibrous pulp of which the paper is to be made.
CORNELIUS T. TOMKINS. Witnesses:
AMos BROADNAX, H. (l. Henson.
