PROVISIONAL SPECIFICATION.
Improvements in Copying Inks, Copying Books, and Appliances.
HARVEY BEALES of No. 1 Park Street Avenue Bristol, Stationer, do hereby
declare the nature of this invention to be as follows:-
My invention consists of copying inks that are effective without water, brush or
press, by being used with a specially prepared paper or book which is perfectly dry
and does not require any moisture to produce a perfectly legible copy but its
advantages are further developed by use of a pad or appliance which I will hereafter
describe
The ink I make with the following materials:-Softened water, logwood
sulphate of iron, nut galls, glycerine and vegetable black. I also make another
equally effective ink for copying but having the advantage that if any document
written with same should, after copying be saturated with water the ink will not
run or blurr but remain distinct. The ingredients are:-
Softened water, sulphate of iron logwood, pearlash, glycerine and vegetable
black.
The paper or books to be used for copying letters or documents written with
these inks I prepare in manner following. I saturate the sheets of tissue paper
before or after biuding with a solution made with the following materials water,
glycerine loafsugar and nitrate of silver.
The pad used in copying I prepare in following manner.
India rubber cloth stretched on cardboard or millboard this pad placed under
the letter or document to be copied and the sheet of copying paper being placed
over it a copy is produced by simply drawing the hand across it without moisture,
press or any other appliance.

COMPLETE SPECIFICATION.
Improvements in Copying Inks, Copying Books, and Appliances.
I, HARVEY BEALES, of 1 Park Street Avenue, in the City and County of
Bristol, Stationer, 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 consists in a copying ink of special composition whereby copies of
letters and other documents written with the said ink are obtained without the use
of water and the usual copying press. The invention extends also to a pad designed
to facilitate the operation of copying
The ink comprised in this invention is prepared by first mixing together, in
approximately the proportions stated, bruised nut galls 14 oz.; logwood chips, 8 oz. ;
and soft water 1 gallon. The mixture is subjected to the action of heat, that is to
say, it is allowed to simmer gently for a period of about 12 hours. At the end of
this period the compound is strained while still hot, loss of water due to evaporation
being afterwards made up to the gallon with soft water. To the compound is then
added pure sulphate of iron, 6 oz.; gum arabic, 2 oz., and cloves, 1 oz.
At frequent intervals during a period of about 14 days the compound is
stirred and at the expiration of the said period it is strained, and to the strained
compound a further addition is made of vegetable black ground in conjunction
with pure glycerine, the addition being made while the mixture of vegetable
TDA71

page_text: black and glycerine is in a hot state. The approximate proportions of pure
glycerine and black are 3 lbs. of the former to oz. of the latter. The ink so
compounded and prepared is of a deep black hue.
The paper for taking copies of documents written with the ink prepared as
above described is a tissue paper such as is usually employed in letter books
and otherwise for obtaining press copies. It should, however, be thin and of fine
quality.
In the Provisional Specification left with my application for Letters Patent to
this invention it is set forth that the paper is saturated with a solution composed of
sugar, nitrate of silver, water and glycerine.
I find, however, that such preparation of the paper is not necessary to the рго-
duction of copies of documents written with the specially prepared ink which
constitutes a part of this invention, and that, as above stated, copies of letters and
other documents may be taken on ordinary press-copy tissue paper. The copies
are taken by laying the tissue paper over and upon the writing which is reproduced
on the tissue paper by merely laying the hand on the tissue paper superposed on
the writing and drawing the hand over the same. The tissue paper does not
require to be moistened and the employment of a copying press is dispensed with.
For the purpose of keeping letters and other sheets steady when laid for copying
according to my process a specially prepared pad constituting part of this invention
is employed. This consists of a sheet of india-rubber stretched on card-board or
mill-board as a backing. The document to be copied is laid on the india-rubber
face of the pad prior to superposing on the face of the document the sheet of
copying paper on which the copy is to be produced.
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 copying ink for producing copies on tissue paper of letters and other
documents without involving damping of the sheets on which the copies are taken
and without the use of a copying press, the said ink being compound and prepared
substantially as hereinbefore described, the copies being obtained by laying the
hand on and drawing it over the tissue paper below which the writing to be copied
is placed.
2. A pad for preventing letters and other documents from shifting while being
copied, as hereinbefore described, the said pad consisting of a sheet of india-rubber
stretched on card-board, mill-board or other suitable substance, as set forth.
Dated this 20th day of August 1891.
