PROVISIONAL SPECIFICATION.,
A New or Improved Method of Preparing Dies or Counterparts and
Matrices therefrom for Embossing or Raising Excresences upon
Plain, Printed or Lithographed Sheets of Paper.
I, WARWICK SAVAGE Wellington House 190 Waterloo Road, Burslem, Stoke-
on-Trent, Staffordshire, Lithographer, Printer & Stationer, do hereby declare the
nature of this invention to be as follows;-
This my Invention has reference to a new or improved method of preparing
dies or counterparts, and matrices therefrom for embossing, or raising excresences
upon plain, printed or lithographed paper sheets, the object of my said Invention
being to economise labour and time, and to more accurately represent on paper the
articles, or objects illustrated.
In carrying my said Invention into practice for embossing Litho' printed sheets
I first take an impression on to card, or similar suitable material from a keystone
of the design, pattern, picture or lettering, then I take a semi-liquid paste made of
or from liquid gum and illuminator's raising paste in suitable proportions, which
semi-liquid paste by means of a brush, pencil or like appliance I apply layer upon
layer within or about the lines of the said design, pattern or picture upon the said
card until the desired height or heights of the several prominences are attained,
which excresences I allow to dry or become hard, after which such excresences
may be waterproofed by means of a covering of white spirit varnish or the like
laid or painted over same by using a brush or other suitable means. Such cards
with the excresences thereon I then attach or secure to the cylinder of litho'
printing machines by means of gum, glue, or a mixture of Plaster of Paris and
glue, so that the excresences on such card shall be outward.
Then I prepare a blanket of any suitable shape, size and thickness of any suitable
number of sheets of brown paper, blotting paper or the like suitable material which
have been caused to adhere together by glue, or other suitable adhesive, such
blanket I lay upon and cause to adhere to a wood-block, stone-block or metallic-
block of suitable size which has been fixed or secured on, or to the bed of a suitable
litho' machine by means of a compound or mixture of Plaster of Paris, liquid
glue and size in suitable proportions, and before such compound or mixture has
set or become hard I operate or work the cylinder to which the card is attacked,
and the block to which the blanket is secured, so as to form a matrix of the said
prominences on the card in the blanket on the wood, stone or metallic block in
the bed of such machine. After such matrix in the blanket has set or become
hard a plain, printed or lithographen sheet may be fed into such cylinder printing
machines in the usual way for having prominences formed on their face, or
illustrated side.
In letter-press printing machines the card, thin gelatine, thin cloth, thin leather,
card-board or the like suitable material having excresences formed thereon is
attached to the platen or cylinder of a suitable printing machine. A blanket of
suitable shape, size and thickness being made of any suitable number of sheets

page_text: of brown paper, blotting-paper or the like suitable material secured together by
size, one side of such blanket I cover with a mixture of Plaster of Paris and liquid
glue in suitable proportions so as to cause such blanket to adhere to a wood, stone
or metallic block fixed on, or to the bed of such machines.
In the case of platen printing machines such platen is closed or shut down,
and the machine operated, so that the protuberances or prominences on the
card, or like material affixed to such platen will be impressed into the blanket
on the metal, wood or stone block in the bed of the machine before the size between
the paper sheets forming the blanket has set, or become hard, and so formi a matrix
of such prominences in such blanket.
After such matrix has set or become hard, plain, printed or lithographed sheets
may be placed in such machines in the ordinary way for having excresences or
prominences formed on the front or face side of such sheets.

A New or Improved Method of Preparing Dies or Counterparts and
Matrices therefrom for Embossing or Raising Excresences upon
Plain, Printed or Lithographed Sheets of Paper.
I, WARWICK SAVAGE Wellington House 190 Waterloo Road, Burslem, Stoke-
on-Trent, Staffordshire Lithographer, Printer and Stationer, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
This my Invention has reference to a new or improved method of preparing
dies or counterparts and matrices therefrom for use in embossing or raising
excresences upon plain, printed or lithographed sheets of paper, the object of my
said Invention being to economise labour and time, and cause illustrations on
paper to more accurately represent the articles or objects intended.
In carrying my said Invention into practice for embossing litho' printed sheets
of paper I first take on to card, zinc or like similar suitable material an impression
of the selected design from a keystone of such design, in the case of letter press
printing I take such impression from a type or block of the design, then I take
a semi-liquid paste made of or from liquid gum and illuminators' raising paste.
in suitable proportions, for example one part of liquid gum and two parts of
illuminators' raising paste, which ingredients after being thoroughly mixed together
to form such paste I by means of a camel-hair brush, pencil or like suitable
appliance paint layer upon layer within or about the lines of the impression of
such selected design, pattern or picture upon the said sheet or piece of card, zinc.
or like suitable material until the desired height or heights of the several pro-
minences are attained so as to form a model of such design, after allowing the said
paste excresences to thoroughly dry or become hard I reproduce the said model in
the same manner as an electrotype is made as is well known to the trade, which
electrotype I firmly attach or secure by glue or other suitable means to the platen,
of a platen printing machine.
I then take a blanket of any suitable thickness made of or from a suitable
number of sheets of brown paper, blotting paper or like suitable material which
have been caused to adhere together by gum, glue, paste, plaster of Paris or like
suitable adhesive and secure or fasten such blanket by glue or like suitable

page_text: adhesive to a flat block of any suitable wood, or like suitable substance in the bed
of such platen printing machine.
Before the adhesive between the several sheets of paper or like suitable material
of which the aforesaid blanket is composed has become dry or set I close the platen
of the machine to which the electrotype is attached or secured so as to cause the
excresences on such electrotype to indent or penetrate the outer surface of the said
blanket and form impressions or moulds of such excresences in such blanket.
After the said adhesive between the several sheets forming such blanket has
thoroughly set I feed sheets of thin paper, thin leather, thin celluloid, or thin curl-
ward of suitable size which require embossing into such machines in the ordinary
way.
The above process can be applied to cylinder letter press or lithographic machines
by fixing or securing the electro' formed by any suitable means to a block of wood
or like suitable material of suitable height or thickness and lacking or securing
such block in the bedof the cylinder letter press or litho' printing machine in the
usual way, a paper or similar blanket of suitable size made as before described
is then attached by any suitable means to the cylinder of the machine to be used,
and such cylinder revolved before the adhesive between the sheets of such blanket
has set or become dry so as to form a mould or female die of the several excresences
on the face of the electrotype in such blanket.
The sheets requiring to be embossed are fed face downwards into litho' printing
machines, and face upwards into letter press printing machines.
An alternative method of making the mould or female die for platen letter press
printing machines is by taking a flat piece or table of any suitable wood or like
suitable material of suitable shape, size and thickness, around the sides or edges
of which table I fasten or secure by nails or like suitable means pieces or strips of
wood or like suitable material of suitable width and thickness so as to extend an
equal height above and around the surface of such table and form a trough of
suitable depth, which trough I fill with a mixture of Plaster of Paris and alum
water in suitable proportions so as to form a plastic compound or paste with a
level upper surface, upon the surface of such plastic compound within such trough
I place a sheet of common white or coloured paper of any suitable thickness which
paper will adhere to the top surface of such plastic compound.
Such table or trough containing such plastic compound with the paper on its
upper surface whilst the said mixture or compound is in a plastic condition I fix
or secure in the ordinary way, or by other suitable means to the bed of a platen
printing machine and close the platen of such machine so as to cause the several
prominences on the face of the electrotype which has been previously secured or
fastened to the platen of such machine to indent or form depressions in such sheet
of paper and the plastic compound beneath such paper and so form a mould or
female die, which mould when set may be used at any length of interval for em-
hossing paper, thin leather, thin celluloid or thin cardboard sheets without being
renewed or replaced as the paper upon the surface of such compound tends to
lengthen the life of such mould or female die by preventing the chipping of the
compound of or from which such die or mould is composed or made the electrotype
when once made undergoing little or no deterioration in use.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is;-
1st. The improved method of preparing dies or electrotypes and matrices er
female dies therefrom for use in platen or cylinder printing machines for em-
bossing plain, printed or lithographed sheets of thin paper, thin cardboard, thin
leather or thin celluloid by first taking an impression of the selected design, pattern
or picture on to card, zinc or like suitable material from a keystone block or type
of such selected design, pattern or picture, then painting layer upon layer by
using a brush, pencil or like suitable appliance a semi-liquid paste composed of

page_text: liquid gum and illuminators' raising paste in suitable proportions within or about
the lines of the impression of such design, pattern or picture until the desired height
or heights of the several required prominences are attained, and when the said
several prominences are thoroughly set or dry reproducing the model in the same
manner as electrotypes are made, which electrotype when set is firmly secured to
the platen of a platen printing machine or to the bed of a cylinder letter press
or litho' printing machine and a mould or female die formed in the paper or other
blanket of such machines as herein substantially described and set forth.
2nd. The method of constructing moulds or female dies from electrotypes made
as described in Claim 1 and for use in connection with such electrotypes by first
pouring a plastic or semi-liquid mixture of Plaster of Paris and alum water into
a trough of suitable size and depth, afterwards placing or spreading a sheet of
common white or coloured paper of suitable thickness on the surface of such com-
pound while plastic so that such paper will adhere to such compound, then securing
such trough containing such plastic compound to the bed of a platen printing
machine, and whilst such compound is in a plastic condition forming a mould or
female die in such compound from the several prominences on the electrotype
attached to the platen of such machine in the manner as herein substantially
described and set forth.
