United States of America, Gentleman.]
1, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co. Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature of
the said invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
The invention relates to the method of preparing and using blue which comprises
the application of a blueing solution to strips or sheets of paper of any desired size,
which sheets act to hold the blue for transportation, and also as a means by which
the blue is introduced into the water or washing solution.
Heretofore these sheets have been prepared for use by coating both surfaces of the
sheet with blueing composition, and by saturating the sheet with a blueing com-
position, so that the entire sheet is covered upon both sides, or filled with the blueing
composition. And these sheets have been loosely packed in envelopes for trans-
portation or for the market. When the blueing sheets or strips are thus prepared it
is necessary in using them to submerge the entire sheet or strip in water or other
liquid to which the blueing is applied, and as this is done by hand it follows that this
cannot be done without wetting and blueing the fingers to a greater or less extent;
and as the sheets are packed together in an envelope it is practically impossible after
one sheet has been taken from the envelope to take another sheet therefrom without
wetting some of the sheets in the envelope which may spoil them to some extent.
My invention is designed to obviate the objections which arise from this manner of
preparing the blueing for use. And it comprises, first, a blued sheet or strip, which
consists of a sheet or strip of paper saturated or coated with a blueing solution upon
a portion of one or both surfaces, leaving a portion of the sheet uncoated or
unsaturated with the blueing.composition, which acts as a tab whereby the sheet
may be held by the thumb and fingers while the portion of the strip or sheet

page_text: which carries the blueing is introduced into the water or other liquid. The invention
further relates to the assembling of these sheets or pages thus prepared in the
form of a book, with the uncovered sections or tabs at the outer ends of the
blued sheets or strips which make the leaves of the book. The inner ends of
the sheets or strips being secured to each other in any desired way, and preferably
within covers or paper, or any other suitable material. The sheets are preferably
perforated or weakened close to the seam uniting them together, so that they may
be readily detached or removed from the book.
In the accompanying drawing.
Figure 1 represents a perspective view of the leaves or sheets incorporated in
a book, the same being represented open.
Figure 2 is a section through the book when closed.
A represents the sheets or strips carrying the blue, a represents the portions of the
sheets, strips or leaves covered or saturated with the blueing composition and a¹ the
tab ends thereof which are free from blue.
In preparing these sheets or strips for use I take paper of any suitable quality,
preferably manilla paper, and cut it to the form of the sheet or strip desired. I then
prepare a composition of blueing, which may be made in any desirable way, but
which I prefer to make substantially as follows;
One solution which is desirable for this purpose I make by taking soluble
prussian blue, or a suitable aniline blue, and dissolve the same in water, so as to
obtain a solution as concentrated as possible. In case aniline blue is used there
should be added some acetic acid to the water in order to develop the color
thoroughly. There may be added to the solution dextrine, starch, or other suitable
thickener. I would say, however, that there are other ways of making a solution
suitable for application to paper in the manner specified, and that I do not confine
myself in practising my invention to the one herein specified.
Into this solution the sheets or strips are dipped by their tab ends, and so that
about from two-thirds to three-quarters of each strip or sheet shall be emersed in
the solution, and they are allowed to remain therein sufficiently long to properly
receive the blue. If the paper is of a porous character its substance is more or
less saturated with the solution; if it is not porous then the blueing covers the
surfaces thereof, submerged in the composition as a coating or layer. The sheets
thus prepared when dried are brought together, and so that their tab ends shall
be upon the same line and they are then united at their opposite or blued ends
by any desirable means. I have represented them in the drawings as secured
together by thread, but I would say that I do not confine myself to this means
of attaching them, as they may be secured together in any desirable way.
I prefer as a rule to enclose them within a cover B, of a size sufficient to cover
and protect the blued sheets, and when a cover is used the sheets are assembled
within it, and are united to each other and to the cover by thread or other
fastening passed through the cover and close to its back, the cover generally
being formed from a strip of unblued paper of somewhat more than twice the
length of the blued sheets.
Where thick or tough paper is employed for the blued sheets or leaves I prefer
to perforate or otherwise weaken it close to the line of the fastening securing them
together, in order that the leaves or sheets may be easily detached from the book.
I would say that the book form for holding the blued sheets or leaves can be
employed where the sheets or leaves are entirely covered or saturated with
blueing. I would also say that I do not confine myself to the especial form or
arrangement of the sheets or leaves and cover represented in the drawings, nor to
the special location of the tab in relation to the portions of the sheets or leaves
saturated or covered with blue, nor to the special method of obtaining such tab,
as I consider that my invention involves a blueing sheet or leaf which shall have
a portion of its substance arranged or adapted to carry blue either by saturation
or by coating, or both, and which shall also have either integral therewith or
affixed thereto an unblued tab or section by which the sheet or leaf can be handled

page_text: without soiling or dirtying the fingers. I would say also, that I do not confine
myself to the use of paper as a means for carrying the blue, but may use in lieu
thereof any other suitable material.
It will be observed that by this form of blued sheet or leaf and method of
securing them together, not only can the sheets be used without soiling the
hands or anything else, but that they may be used more economically, as the leaves
are held together as a book until the time of use, and only as many are then removed
from the book as may be needed for properly preparing the water or liquid.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed as communicated to me by my
foreign correspondent I declare that what I claim is :-
First. As a new article of manufacture, a blueing leaf, sheet or strip, comprising
a sheet, strip or leaf of paper or other suitable material coated or saturated with a
blueing composition, and having a tab end free from blue by which it may be handled
in use, as and for the purposes described.
Second. The blueing sheet, strip or leaf of paper or other suitable material, having
the section a saturated or coated with a blueing composition and the section a¹ free
from blue, as, and for the purposes described.
Third. As a new article of manufacture, a blue book consisting of a number of
sheets or leaves of paper or other suitable material, coated or saturated with a blueing
composition connected with each other, and with covers for enclosing the same, as
and for the purposes described.
Fourth. The blue book, comprising a number of sheets leaves or strips of paper or
other material, sections of which are coated or saturated with a blueing composition,
and sections of which are uncoated or unsaturated, and which are used for tabs,
united together and to their holding covers, as and for the purposes described.
Fifth. The blue book, comprising the covers B, the blued sheets or leaves A, having
the blued sections a and the tab ends a¹ united to each other and to the cover, and
having perforations or being weakened close to the line of the attaching seam, as and
for the purposes described.
