Improvements in Blotting Paper.
Year: 1898

page_text: Date of Application, 14th Feb., 1898
Complete Specification Left, 30th Sept., 1898-Accepted, 5th Nov., 1898
FREDERICK ARTHUR ROUSE, 4, Montpelier Road, Kentish Town, London, N.W.,
Clerk, do hereby declare the nature of this invention to be as follows:--
A number of perforations or indentations are made in the blotting paper from
both sides, causing a series of projections on both surfaces of the sheets of paper,
so that the ink from the written matter blotted is absorbed more quickly and
irregular, instead of taking a fac-simile of the written matter on the blotting paper
as at present.
The perforations indentations and the like, may be made during the manufacture
of the paper or afterwards, as may be found desirable.
The designs of the perforations indentations and the like may be varied.
A non-perforated margin may be left on each sheet of blotting paper.
As modifications, small holes and the like, may be taken out of the blotting
paper or a number of small dots, curves, or circles, impressed or printed thereon.
The holes dots and the like, may be made on one side of the blotting paper,
or both.

Improvements in Blotting Paper.
FREDERICK ARTHUR ROUSE, 4, Montpelier Road, Kentish Town, London, N.W.,
Clerk, 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:-
-
My invention relates to an improved blotting paper" and has for its object the
production of a blotting paper that will not take a fac-simile of the written matter
blotted on its surface in such a manner that it can be deciphered or easily read on
an examination of the blotting paper being made.
It is well known that much valuable information has been surreptitiously
acquired through the examination of a sheet of used blotting paper.
The present invention is particularly designed to overcome this difficulty.
In order that my invention may be clearly rendered, I now proceed to describe
it more fully.
+
I take a sheet or number of sheets of ordinary commercial blotting paper and
pass them under a plate studded with needle points and on pressure being applied

page_text: as for example in an ordinary copying press the needle points cause the paper to
be perforated or indented thus leaving a number of projections on its surface, with
the result that the ink from any written matter blotted would be absorbed in a
more irregular manner than hitherto.
I do not confine myself to this one method of carrying out my invention as it
is obvious it may be done other ways, for instance, rollers studded with needle
points may be used, or an ordinary perforating machine may be made use of, so long
as perforations or indentations are made in the paper, but to come within the scope
of my invention it is necessary that the paper be pierced or cut through.
The perforations and the like may be made on or from one or both sides of the
paper.
To better illustrate what I mean I give the following example.
Blotting paper for use in a blotting pad would only require to be treated from
one side and the surface of the paper with the raised projections would be placed
uppermost for the written matter to be blotted on, whereas, blotting paper to be
used in single sheets would preferably be perforated or indented from both sides
causing the projections or throwing out to appear on both surfaces of the paper.
By the use of needle perforation practicaly none of the paper is wasted during
the process but as a modification a number of holes may be punched out of the
paper by a punching machine or the like.
In order that the blotting paper may be more firmly held together I leave a
plain untreated margin on each sheet of paper.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A blotting paper perforated, cut, or indented, upon one or both of its surfaces
substantially as and for the purpose herein described.
2. A blotting paper perforated, cut, or indented, substantially as herein described
but having a plain untreated margin left in order that the paper may be more
firmly held together.
Dated this 28th day of September 1898.
