Year: 1880

page_text: LETTERS PATENT to Henry Thornton and Francis Edward Walmsley, both of
Bowling Green Lane, Farringdon Road, London, in the County of Middlesex,
Bookbinders' Cloth Manufacturers, for an Invention of "IMPROVEMENTS IN
THE MANUFACTURE OF BOOKBINDERS' CLOTH."
PROVISIONAL SPECIFICATION left by the said Henry Thornton and Francis
Edward Walmsley at the Office of the Commissioners of Patents on the 26th
January 1880.
HENRY THORNTON and FRANCIS EDWARD WALMSLEY, both of Bowling Green
Lane, Farringdon Road, London, in the County of Middlesex, Bookbinders'
Cloth Manufacturers. "IMPROVEMENTS IN THE MANUFACTURE OF BOOKBINDERS'
CLOTH."
The manufacture of bookbinders' cloth as at present carried out is by printing or
dyeing the cloth, then stiffening or filling with paste, then calendering to close up
and finish the cloth, after which it may be embossed.
We propose to take the cloth when dyed or printed, and instead of filling or
stiffening the same with paste in the ordinary manner, to back the cloth with
paper, fixed thereon by a solution of gum or other suitable adhesive substance,
which we apply in any convenient manner. We then propose to fix the paper
securely upon the cloth by passing the two materials thus combined between
rollers, or otherwise pressing them closely together, and we finally. callender or
emboss the cloth thus prepared.
This mode of manufacture will afford (amongst others) the following advantages:-
The cloth will be found to be much stronger, it will approach more nearly the
substance of leather, thereby facilitating the blocking, the glue used by the book-
binder cannot possibly come through on to the face, and the colors will not in any
case be injured.

Patent Office on the 24th July 1880.
HENRY THORNTON and FRANCIS EDWARD WALMSLEY, both of Bowling Green
Lane, Farringdon Road, London, in the County of Middlesex, Bookbinders'
Cloth Manufacturers. "IMPROVEMENTS IN THE MANUFACTURE OF BOOKBINDERS'
CLOTH."
The manufacture of bookbinders' cloth as at present carried out is by printing
or dyeing the cloth, then stiffening or filling with paste, then calendering to close
up and finish the cloth, after which it may be embossed.
Our Invention relates to the production of a new article of manufacture for book-
binders' use, which we term lined cloth, and which we make as follows:-We take
the cloth when dyed or printed, or we take it in the white or bleached state, as we
may prefer, and instead of filling, stiffening the same with paste, and calendering
to close up in the ordinary manner, we back the cloth with paper, fixed thereon by
a solution of gum or other suitable adhesive substance, which we apply in any
convenient manner. We then fix the paper securely upon the cloth by passing the
two materials thus combined between rollers, or otherwise pressing them closely
together, and we finally callender or emboss the cloth thus prepared.
This mode of manufacture affords (amongst others) the following advantages:-
The cloth is found to be much stronger, it approaches more nearly the substance of
leather, thereby facilitating the blocking, the glue used by the bookbinder cannot
possibly come through on to the face, and the colours will not in any case be
injured.
Having now described and ascertained the nature of our said Invention, and in
what manner the same is or may be performed, we desire it to be understood that
we may use any suitable means or machinery for the purpose of combining
the materials forming our improved lined cloth for bookbinders' use, and that
what-
We claim as secured to us by the hereinbefore in part recited Letters Patent
is,-
The use of bookbinders' cloth formed of a combination of cloth and paper,
substantially as and for the purposes herein before described.
In witness whereof, we, the said Henry Thornton and Francis Edward
Walmsley, have hereunto set our hands and seals, this Twenty second
day of July, in the year of our Lord One thousand eight hundred and
eighty.
