PAPER AFFORDING PROTECTION AGAINST ERASURE OR OTHER ALTERATION
My improvements in the preparation of Safety paper consists in filming a part
of the paper to be protected with a soluble film or films of such a nature that it
will receive a print but will prevent the absolute adhesion of a lightly printed
protective design to the paper itself at such parts as the film covers and I then
print lightly a protective design upon the filmed and unfilmed portions of the
paper so as that if the paper be washed with any solvent of the substance of the
film the superimposed printed design will be removed and part of the design will
remain on the unfilmed portion of the paper. A less perfect protection may be
afforded by the uniform filming of the whole of the paper and the printing thereon
of a protective design and my invention may be combined with any of the other
well known methods of producing safety paper such as the introduction of
Chemicals into the paper itself or in the substance of the protective design or both
or by what is called water-colour printing
One of the principal objects of my invention is to guard against the use for
fraudulent purposes of spurious inks which possess no mordant or dyeing property
and which may be washed off with great facility, and to guard against the filming
of postage and other stamps with such material as would prevent contact of the
obliterating ink with the stamp itself so that in the removal of the film the
obliterating ink would be also removed.
A convenient film for the purpose may be made from a solution of starch and
gum or starch and dextrine and I prefer to apply it either from a fabric such as
tarletan, tulle or net damped with the solution and pressed upon the paper while
passing through rolls or to apply it in the form of fine spray through the interstices
in a grating placed near to the paper but not actually in contact and which grating
if a continuous web be filmed may move with the paper, but there are many other
way of producing the film.

PAPER
My improvements in the preparation of safety paper consist in filming a part of
the paper to be protected with a very soluble film of such a nature as that it will
receive a print but will prevent the absolute adhesion of a lightly printed
protective design to the paper itself at such parts as the film covers; and I then
print lightly a protective design upon the filmed and unfilmed portions of the
paper so as that if the paper be washed with any solvent of the substance of the
film the superimposed printed design will be removed, but the design will remain
on the unfilmed portion of the paper. And my invention may be combined with
any of the other well known means of producing safety paper such as the
introduction of Chemicals in the paper itself or in the substance of any protective
design or both or by what is called water color printing.-The object of my
Invention is to guard against the use for fraudulent purposes of spurious inks
'which possess no mordant or dyeing character and which may be washed off with
great facility and to guard against the filming of postage and other stamps with
such material as would prevent contact of the obliterating ink with the
stamp itself so as that on the removal of the film the obliterating ink would
be also removed.-A convenient film for the purpose may be made from a
solution of starch and gum or starch and dextrine and I prefer to apply it
either from a fabric such as tarlatan, tulle, or net damped with the solution
and pressed upon the paper while passing through rolls or to apply it in the
form of fine spray through interstices of a grating placed near to it but not in
actual contact and which grating if a continuous web be filmed may move with
the paper. Having thus described the nature of my invention I will proceed
more particularly to describe the manner in which the same is to be operated that
is to say-In addition to any precautions already in common use, such as the
introduction of Chemicals in paper as provided in the invention of Barclay
No 1390 or stain of ink to give an uniform tint to paper or the printing of designs
in fugitive colors or chemicals or as a means of superceding such precautions and in
lieu of methods of protecting paper and stamps described by me in Specification of
Patents No 2715 and 271967, and 356 and 102368 (which were in some respects too
complicated) or in combination with any parts of my said inventions, I use a
'soluble film in the form of a pattern or design so as to coat a part but not the
whole of the paper to be protected or more than one such pattern or design and I
combine with it a print superimposed so as in part to be adherent to the fabric of
the
paper and in part to be adherent only to the soluble film and I combine with
this protection the use of such chemicals as is well understood, in the paper, the
film, or the printed designs or in more than one of them as shall produce disfigure-
ment from any attempt to fix or render insoluble the film and I may combine with
these precautions the application of a dry soluble color (such as aniline blue in 'the
form of powder) so that when wetted it will produce a stain from the solution of
the coloring matter which would extend beyond the limits of the application of the
dry color and be difficult to afterwards remove.-I may also combine the use of.
my precautions with the use of water mark in paper such as it would be both
expensive and difficult to imitate, the use of such water mark being confined
exclusively in so far as it could be so arranged t paper protected by my invention.
The film I prefer to use I make of starch and gum or starch and dextrine or any

page_text: convenient materials of similar character, the starch being intended to take off the
glaze which would be given by the use of gum alone, but any material of a similar
character may be used.-I prefer to print the film design on to the paper either as
a paper stainer applies his colors to the continuous web of paper or by means of a
fabric of net impregnated with the solution and in a moist state applied by the
pressure of a roller to the band of paper, but it may be applied in any other
convenient way. The superimposed design I apply either in a similar manner to
that already described for applying the film design or by printing in any description
of printing machine adapted to the purpose or from engraved rollers, plates or
lithographic stones, and for Cheques or Bills of Exchange or such documents, the
protective print may be made to form part or the whole of the ordinary printing of
the cheque. The film (in the form of a design or otherwise) may also be used for
the protection of postage stamps so as that if a postage stamp be filmed all over for
fraudulent purposes as may be done at present, the wetting required to remove the
obliteration will also effect the removal of part of the designs of the stamp and so
disfigure it.
Having now described the nature of my invention and the manner in which the
same is to be performed I would have it understood what I claim as my invention
is, 1st The use of soluble film in the form of design on paper to be protected against
erasures or alterations in combination with a superimposed print in part adherent
to the paper and in part carried upon the soluble film with or without other
precautions substantially as described. 2nd The use of soluble film substantially as
described for security of postage stamps against frauds now possible.
In Witness whereof I the said John Jameson have hereunto set my band and
seal this twenty third day of June in the year of our Lord one thousand eight
hundred and eighty four.
