IMPROVEMENTS IN AND CONNECTED WITH THE MANUFACTURE OF TILES, QUARRIES, SLABS, PLATES, AND THE LIKE
Year: 1880

page_text: LETTERS PATENT to Isaac Broad Shaw, Printer, of Tunstall, in the Parish
of Walstanton, in the County of Stafford, for an Invention of "IMPROVEMENTS
IN AND CONNECTED WITH THE MANUFACTURE OF TILES, QUARRIES, SLABS,
PLATES, AND THE LIKE."
PROVISIONAL SPECIFICATION left by the said Isaac Broad Shaw at the
Office of the Commissioners of Patents on the 17th February 1880.
ISAAC BROAD SHAW, Printer, of Tunstall, in the Parish of Wolstanton, in the
County of Stafford. "IMPROVEMENTS IN AND CONNECTED WITH THE MANUFACTURE
OF TILES, QUARRIES, SLABS, PLATES, AND THE LIKE."
This Invention relates to improvements in and connected with the manufacture
of tiles, quarries, slabs, plates, and the like.
"
Hitherto the decoration of tiles, quarries, slabs, plates, and the like, has been.
effected by the processes known as "stencilling," "transferring," or "hand-painting; "
now by my Invention this operation is effected by machinery, whereby rapidity
and economy in production are obtained, and one or more tiles may be decorated
at one and the same time.
In carrying out my Invention I employ an ordinary printing machine, and the
design is printed upon the tiles, quarries, slabs, plates, and the like direct,
whether in one or more colours, by means of elastic printing surfaces, which may be
prepared as follows:-
For example, if it is desired to produce a design in four colours upon a tile or
plate, I take wood cuts or other blocks of the design to be printed on the tile,
and from this block or plate I take casts in any suitable elastic composition, such
as vulcanized india rubber, and then mount the said cuts on wood or the like in
different sections, that is to say, a separate section or block for cach colour, and
they are then ready for the printing press or machine. I then prepare the colour
duct of the machine for the colour (suitably prepared as hereinafter described) to
be first printed on the tile, and then fix the first colour of the design in its proper
place on the printing machine, and having made ready or adjusted the guides of
the platen on which the tiles are placed, all is ready to proceed with the working-
off of the first colour of the design. The first colour being printed on as many

page_text: of the tiles as are required, I clean up the colour duct and rollers for the second
colour, and then fix the second colour of the elastic design in place of the first,
and in this manner proceed until the whole design in the various colours is
completed, and by this means I obtain accuracy of register for each particular
colour necessary to the completion of the design to be printed on the tiles.
I have found it advantageous to prepare the colours for use by grinding them
up to a thick consistency with the best varnish used by letter press printers for
machine work with a slight addition thereto of balsam copaiva.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Isaac Broad Shaw in the Great Seal Patent Office on the 16th
August 1880.
ISAAC BROAD SHAW, Printer, of Tunstall, in the Parish of Walstanton, in the
County of Stafford. "IMPROVEMENTS IN AND CONNECTED WITH THE MANUFACTURE
OF TILES, QUARRIES, SLABS, PLATES, AND THE LIKE.”
This Invention relates to improvements in and connected with the manufacture
of tiles, quarries, slabs, plates, and the like.
Hitherto the decoration of tiles, quarries, slabs, plates, and the like, has been
effected by the processes known as "stencilling," "transferring," or "hand-painting;"
now by my Invention this operation is effected by machinery, whereby rapidity
and economy in production are obtained, and one or more tiles may be decorated
at one and the same time.
In carrying out my Invention I employ an ordinary printing machine, and the
design is printed upon the tiles, quarries, slabs, plates, and the like direct, whether
in one or more colours, by means of elastic printing surfaces, which may be prepared
as follows:-
For example, if it is desired to produce a design in four colours upon a tile or
plate, I take wood cuts or other blocks of the design to be printed on the tile, and
from this block or plate I take casts in any suitable elastic composition, such as
vulcanized india rubber, and then mount the said cuts on wood or the like in
different sections, that is to say, a separate section or block for each colour, and
they are then ready for the printing press or machine; or the elastic design may
be fixed on the bed or carriage of the press or machine or on the tympan, according
to the size or extent of the design. I then prepare the color duct of the machine
for the colour (suitably prepared as hereinafter described) to be first printed on the
tile, and then fix the elastic section or block for the first color of the design in its
proper place on the printing machine, and having made ready or adjusted the
guides of the platen on which tho tiles are placed, all is ready to proceed with the
working off of the first color of the design. The first color having been printed
on as many of the tiles as are required, I clean up the color duct and rollers for
the second color, and then fix the section or block of the elastic design for the

page_text: second color in place of the first color block, and in this manner proceed until the
whole design in the various colors is completed, and by this means I obtain
accuracy of register for each particular color necessary to the completion of the
design to be printed on the tiles. By these means I can also print or decorate
the intaglio or sunk parts of the designs in embossed tiles and the like.
I have found it advantageous to prepare the colors for use by grinding them up
to a thick consistency with the best varnish used by letter press printers for
machine work with a slight addition thereto of balsam copaiva.
Having thus described the nature of my said Invention, and the best means
with which I am acquainted for carrying the same into effect, I would have it
understood that I do not confine myself to the precise details herein laid down,
as the same may be varied without departing from the peculiar character of my
Invention, but what I claim is,—
Firstly. Printing decorativo designs direct upon tiles, quarries, slabs, plates, and
the like, in the manner substantially as herein described.
Secondly. The use for printing decorative designs direct upon tiles, quarries,
slabs, plates, and the like, of clastic printing blocks or sections, as hereinbeforo
described.
In witness whereof, I, the said Isaac Broad Shaw, have hereto set my hand
and seal, this Sixteenth day of August, in the year of our Lord One
thousand eight hundred and eighty.
ISAAC BROAD SHAW. (L.S.)
