PATENT OFFICE.
WILLIAM N. CLARK, OF CHESTER, CONNECTICUT.
IMPROVEMENT IN MAKING PAPER-PULP FROM IVORY.
Specification forming part of Letters Patent No. 18,190, dated September 15, 1857. i
To all whom it may concern:
Be it known that I, WILLIAM N. CLARK, of
1 Chester, county of Middlesex, and State of Connecticut, have discovered a new Material for Making Paper; and I do declare that the fol, lowing is a full and exact description.
The nature of my invention and discovery consists in the use of ivory as stock to make pulp for the manufacture of paper, either separately or byeompounding it with other known materials, and also that by the use of ivory for pulpvpaper can be made without the use of bleaching-chemicals.
To enable others skilled in the art of making paper to use my discovery, I will proceed to describe my invention and discovery.
I take ivory and first reduce it by sawing, shaving, or'dry grinding, and then pass it to the heating or paper engine, where it isrduced to pulp may be used separately to make paper,vo r may be, mixed and beat with pulp made from other known materials.
Pulp made of ivory will make paper more substantial and durable-for. records than any' othermaterial known,asnochemicalsarenecessary to bleach the pulp. Consequently no acids exist in the paper after it is made to destroy the life of the ink or impair the strength and durability of the paper, as is the case when chemicals are used.
What [claim as my invention and discovery, and desire to secure by Letters Patent, is.-
The using of ivory as stock to make pulp for the manufacture of paper.-
WILLIAM N. CLARK". [L. s.] Witnesses:
ALLEN A. SMITH, WILsoN H.'GLARK.
