I, SAMUEL MIDDLETON, of 15, Whitefriars Street, in the City of London;
Mechanic, do hereby declare the nature of the Invention for "IMPROVEMENTS
IN COMBINING AND PREPARING SURFACES OF PAPER AND OTHER MATERIALS FOR THE
PURPOSE OF PREVENTING FORGERY OR FRAUD IN THE MANUFACTURE OF BANK NOTES,
CHEQUES, BILLS OF EXCHANGE, OR OTHER VALUABLE DOCUMENTS," to be as
follows:-
Many attempts have been made to manufacture bank notes, cheques, bills
of exchange, or other valuable documents, which cannot be split, photographed,
or otherwise imitated for the purpose of forgery or fraud, and I am aware
that devices have been printed in different colors, and that materials have
been introduced into the substance of the paper for this purpose, but hitherto
such plans have failed in affording sufficient security against forgery and fraud;
and my Invention consists in combining and preparing the surfaces of paper
and other materials used in the manufacture of bank notes, cheques, bills of
exchange, or other valuable documents, that they cannot be split, photographed,
or imitated by other means without being readily detected.
For this purpose in place of printing the whole of the writing or device in
one or more colors upon the front surface of the paper intended for a bank
note or cheque, I prepare or print one portion of the writing or device upon

page_text: one piece of thin paper, and the other portion of the writing or device upon
another piece of thin paper, and I cement or unite these two separate portions
of the device together by gutta percha, india-rubber, or other suitable cement,
or I place a very thin sheet of gutta percha or india-rubber, or their compound,
between the two pieces of paper with one portion of the writing or device on
the interior surface, and by the application of heat and pressure I firmly unite
them together, and that portion of the writing or device on the inner surface
will shew through, and by correctly registering with the printing on the
external surface will make up the entire device; or the external portion of the
writing or device may be printed or written after the separate parts are com-
bined together.
The device on the inner and outer surfaces may be in différent colors, and
such as cannot be readily copied by the aid of photography, and the material
introduced between the two surfaces of paper thus prepared and combined
may be a perforated design, or the paper upon which each portion of the
writing or device is printed may be perforated, the perforations on one surface
being covered by the other surface when combined as before described; or in
place of cementing two surfaces of paper, each having part of the device
written or printed thereon, I write or print one part of the device on one side,
and the other part on the other side of the same piece of paper, and then
cement anotlier piece of paper (plain or otherwise) on one side, so that part of
the device would be enclosed between the two surfaces.
And my Invention also consists in covering part of the device with paper in
a state of pulp, in place of cementing as before described.
