Improvements in and relating to the Embossing of Designs, Letters,
Figures, Prints, or Patterns.
I, THOMAS ELLIOT BAIRD of the firm of Alexander Baird and Son, Artistic
Stationery Manufacturers, of Kelvinbridge, Glasgow, Lanarkshire, do hereby
declare the nature of my invention to be as follows:-
This invention has reference to and comprises a new or improved process or
method and mode and means of embossing plain, lithographed, or printed patterns,
prints, designs or letterings in sheets of any size by the use of stones, plates, or
other blocks in the usual printing or lithographing machines or presses, in contra-
distinction to having as heretofore or hitherto to emboss these with metal
engraved or other plates in separate embossing machines or presses.
Hitherto in the process of lithographic or block printing, in sheets ornamental
prints, patterns, letterings, tickets, cards, and the like, in colors or bronzes, which,
had to be embossed, the printing only, was done with these lithographic or printing
machines and the sheets or cut up individual parts thereof so printed, were and had
to be embossed with engraved dies, plates, or electro copies of these, in screw and
other powerful embossing presses or machines, and by careful individual means of
registering the patterns of each on the dies by points, guides, and other trouble-
some means, taking up much time and causing the embossing to be so expensive as
to be impracticable for the ordinary class of lithographed or printed work.
By my improvements I effect the whole printing and embossing from stones,
plates, or blocks, in the ordinary lithographic or printing machines or presses
embossing and registering the whole sheet or patterns and designs on said sheet in
the same manner and with the same rapidity as an extra printing, only instead of
being colored or printed, by means of an engraved stone, plate, or other block, it is
embossed in passing through the machine all as hereinafter described. I first print
or lithograph the sheet of designs, figures, letters, prints or patterns in all the
different colors or bronzes each from their respective stones in the usual manner
of lithographic or block printing. For the embossing however of the whole or
parts of these sheets, I use a last lithographic stone, plate or block, on which I
take a transfer or impression from the outline keystone or block, or any of the
color stones or blocks I prefer, which may best indicate the designs or other part
or wording to be embossed. I then engrave or cut in intaglio on the surface of
that stone, plate or block, the whole design or other matter so transferred or any
part thereof which has to be embossed, to the desired depth and shape the embossed
parts have to show in relief, when finished. I then place the engraved stone plate
or block in the carriage of the machine or press, in the same manner and registered
in the same way as the usual colored blocks or stones. I then make what is
commonly known and termed in the trade a "force counter part or "overlay
for the designs so engraved and lay these "forces or counter parts on the stone
plate or block in their proper positions. I then brush or lay over the back of these
counter parts a solution of glue, gum, paste, cement or other adhesive; after this
is done I start the machine or press very slowly and with the usual amount of
pressure, the stone, plate, or block thus passes under the cylinder or platen of the
machine or press and in doing so the counter parts with the adhesive solution on
the back thereof are lifted by the said cylinder or platen from their position on
the said engraved stone or block, thus ensuring a correct and reliable register for the
force
or counter part to the engraved part, and the engraved block plate or
stone being already in register to the printed sheets, these sheets may now be fed
through machine or press in the usual manner and with the same rapidity as if for

page_text: printing, and each sheet will be embossed as it passes through between the engraved
stone plate or block and the force or connection part on the cylinder or platen of
the machine.

This improved process of embossing may also be used for what is known in the
trade as "cameo" stamping or printing, by preparing the stone, plate or block, as
if for lithographing or printing and then engraving in intaglio those parts which
are to be embossed on the same stone or block, as that from which the color is to
be printed, making up a "force or counter part in the manner already described.
The color rollers in passing over the block or stone will color or ink up the part
to be printed only, while the engraved or sunk part of the design will be left free,
thus with one revolution of the machine cylinder, or platen, the sunk part will be
embossed and the flat part printed.
This improved process may also be applied to relief stamping by using brush
rollers in conjunction with the usual color or black rollers, the brush rollers would
color in the sunk parts while the usual color or black rollers would lift or clean off
any of the color or ink which might spurt on to the surface of the stone plate or
block as the brushes were inking the sunk parts, the mode of procedure being all
otherwise as hereinbefore described.

Improvements in and relating to the Embossing of Designs, Letters,
Figures, Prints, or Patterns.
1, THOMAS ELLIOT BAIRD, of the firm of Alexander Baird and Son, Artistic
Stationery Manufacturers, of Kelvinbridge, Glasgow, Lanarkshire, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement in writing, that is to say :-
This invention has reference to and comprises a new or improved process or
method and mode and means of embossing plain, lithographed, or printed patterns,
prints, designs, or letterings in sheets of any size by the use of stones, plates,
or other blocks in the usual cylinder printing or lithographing machines in
contradistinction to having as heretofore or hitherto to emboss these with metal
engraved or other plates in separate embossing machines or presses.
Hitherto in the process of lithographic or block printing, in sheets ornamental
prints, patterns, letterings tickets, cards, and the like, in colors, or bronzes which
had to be embossed, the printing only, was done with these lithographic or printing
machines, and the sheets or cut up individual parts thereof so printed, were and
had to be embossed with engraved dies, plates, or electro copies of these, in screw
and other powerful embossing presses or machines, and by careful individual
means of registering the patterns of each on the dies by points, guides, and
other troublesome means, taking up much time and causing the embossing to be
so expensive as to be impracticable for the ordinary class of lithographed or
printed work.

plates, or blocks, in the ordinary cylinder lithographic or printing machines,
embossing and registering the whole sheet or patterns and designs on said sheet in
the same manner and with the same rapidity as an ordinary printing, only instead
of being colored or printed by means of an engraved stone, plate, or other block,
it is embossed in passing through the machine all as hereinafter described.
In carrying my improvements into practice, I first print or lithograph the sheet

printing. For the embossing however of the whole or parts of these sheets, I use
a last lithographic stone, plate, or block, on which I take a transfer or impression
from the outline keystone or block, or any of the color stones or blocks
which may best indicate the designs or other part or wording to be embossed.
then engrave or cut in intaglio on the surface of that stone, plate or block, the
whole design or other matter so transferred or any part thereof which has to be
embossed, to the desired depth and shape the embossed parts have to show in relief
when finished. I then place the engraved stone plate or block in the carriage of
the machine, in the same manner and registered in the same way as the usual
colored blocks or stones, I then make what is commonly known and termed in the
trade a "force
counter part or "overlay" for the designs so engraved and lay
these "forces or counter parts on the stone plate or block in their proper
positions. I then brush or lay over the back of these counter parts a solution of
glue, gum, paste, cement or other adhesive; after this is done I start the machine
very slowly and with the usual amount of pressure, the stone, plate, or block, thus
passes under the cylinder of the machine and in doing so the counter parts with
the adhesive solution on the back thereof are lifted by the said cylinder from their
position on the said engraved stone or block, thus ensuring a correct and reliable
register of all the raised parts for the "force" or counter part to the entaglio or
engraved part, and the engraved block plate or stone being already in register to
the printed sheets, these sheets may now be fed into the machine in the usual
manner and with the same rapidity as if for printing in the colors, and each sheet
will be embossed as it passes through between the engraved stone plate or block
and the "force or counter part on the cylinder or platen of the machine.

This improved process of embossing may also be used for what is known in
the trade as " cameo
stamping or printing, by preparing the stone, plate, or
block, as if for lithographing or printing and then engraving in intaglio those
parts which are to be embossed on the same stone or block, as that from which the
color is to be printed, making up a "force" or counter part on the cylinder in the
manner already described. The color rollers in passing over the block or stone
will color or ink up the flat parts to be printed only, while the engraved or sunk
part of the design will be left free, thus with one revolution of the machine cylinder,
the sunk part will be embossed and the flat part printed.
This improved process may also be applied to relief stamping by using brush
rollers in conjunction with the usual color or black rollers, the brush rollers would
color in the sunk parts while the usual color or black rollers would lift or clean off
any of the color or ink which might spurt on to the surface of the stone plate or
block as the brushes were inking the sunk parts, the mode of procedure being all
otherwise as herein described.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First. The herein described process or method of embossing or relief stamping
designs, letters, figures, prints, and the like, by the use of stones, plates, or blocks,
in cylinder lithographic and printing machines, substantially as and in the manner
set forth.
Second. The embossing or relief stamping of designs, letters, figures, prints, and
the like, by engraving in intaglio the parts desired to be in relief on stones, plates
or blocks, and making up the pressing surface of the cylinder in relief to suit these
and emboss or stamp previously printed lithographs, in cylinder lithographic and
printing machines, substantially as and in the manner set forth.
