Improvements in the Manufacture of Paper to Render same
Anti-septic and Germ Proof.
We ROBERT DUFFY SINCLAIR, Physician, and Surgeon, of 149 Waddel Street, and
JAMES GRANDISON BROWN of the firm of Brown, and Company, Pattern Book Makers,
of 81 Virginia Street, both in Glasgow, Lanarkshire do hereby declare the nature of
our invention to be as follows:-
This invention relates to a new chemical compound to be used as an ingredient in
the manufacture of paper, and has for its object to render the prepared paper, whether
used for writing, printing, or for other purposes in the various arts in which it may
be applied, more durable and lasting, and antiseptic against the attack of insects, and
germs of decay; while it does not deleteriously affect the usefulness of the paper for
printing or writing, and other purposes, or the colours in which the paper is
manufactured.
And the nature and novelty of this invention essentially consist in incorporating or
impregnating as a mechanical mixture with the constituents of paper, the chemical
compound Resorcin, which belongs to the organic series having the composition C, H
(OH),, and is preferably prepared by fusing galbanum resin with potassic hydrate, or
from the fractional distillation of coal tar.
In carrying this invention into practice, we incorporate the Resorcin, preferably in
the proportion by weight of one in two thousand, with rags, jute, straw, or other
materials used in the manufacture of paper, preferably at the mashing and cutting
stage which precedes the pulp stage, for being thoroughly mixed, or if more convenient
the Resorcin can be added, and mixed with the constituents of the paper at the pulp
stage. And to render the prepared paper nicely flavoured or perfumed, we saturate
with, or add to the water used at the pulp making stage, the oil of the Eucalyptus
Globulous tree, or which is sometimes termed the Blue gum tree, or Fever tree of
Australia.

We ROBERT DUFFY SINCLAIR, Physician, and Surgeon, of 192 Waddell Street, and
JAMES GRANDISON BROWN, of the firm of Brown and Company, Pattern Book Makers,
of 81 Virginia Street, both in Glasgow Lanarkshire do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to a chemical compound to be used as an ingredient in the
manufacture of paper, and has for its object to render the prepared paper, whether
used for writing, printing, ornamental or for other purposes in the various arts in
which it may be applied, more durable and lasting, and antiseptic against the attack of
insects and germs of decay, fungi and disease; while it does not deleteriously affect the
usefulness of the paper for printing or writing, ornamental and other purposes or the
colours in which the paper is manufactured.
And the nature and novelty of this invention essentially consist in incorporating or
impregnating as a mechanical mixture with the constituents of paper the chemical
compound Resorcin, which belongs to the organic series having the composition
CH (OH), and is preferably prepared by fusing galbanum resin with potassic
hydrate, or from the fractional distillation of coal tar.
In carrying this invention into practice, we incorporato the Resorcin preferably in
the proportion by weight of one in two thousand, with the pulp, after the process of
washing the pulp has been completed, the pulp of the paper to be saturated in the said
proportion.
And to render the said paper nicely flavoured or perfumed, we saturate with or add
to the pulp or the paper, a solution of the oil of the Eucalyptus Globulus tree, watery,
spirituous, or otherwise as may be found desirable.
Having now particularly described and ascertained the nature of our said Invention,
and in what manner the same is to be performed, we declare that what we claim is:
1. That the chemical compound Resorcin, either alone or in conjunction with the
oil of Eucalyptus Globulus, has not hitherto been used as an ingredient in the
manufacture of paper, or used to render the same antiseptic and germ-proof.
2. That Resorcin in the proportion stated, and Resorcin with the oil of Eucalyptus
Globulus in the proportion stated, are effective for rendering paper antiseptic and
germ-proof.
3. That they do not injuriously affect the materials of the paper, or the usefulness
thereof, for whatever purpose used, or the colours in which the paper is manufactured.
