New Method of Embossing Lithographed Illustrated Sheets.
I, DAVID PRICE 115 Bucknall New Road, Hanley, Staffordshire, Lithographic
Artist, 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 embossing any
desired portion of plain, printed or lithographed illustrated sheets, the object of my
said invention being to improve the appearance and shape of such illustrations, and
cause same to more accurately resemble the object illustrated.
In carrying my said invention into practice I take three parts of carbonated lime,
two parts of liquid gum, and one part of raw white part of egg (of ordinary
egg-laying fowls) which ingredients while of normal temperature I thoroughly
incorporate or mix together on a marble, or slate slab, or in any suitable receptacle
to form a semi-fluid paste, which paste I paint layer upon layer by a brush, pencil
or other suitable means in suitable positions within or about the lines indicating
the selected pattern, picture or design which has been drawn upon a lithographic
stone or zinc plate, until the desired height or heights of the excresences or
prominences have been obtained, and when such raised surfaces are sufficiently dry
and hard, I brush or coat same with white spirit varnish, so as to render such
raised surfaces or prominences waterproof.
I also take any suitable number of suitably sized sheets of brown paper, blotting
paper or the like suitable material, which sheets I lay one on the other, and secure
same together by glue or the like suitable means to form a suitable blanket, such
blanket I lay upon a flat table or like suitable surface, and brush over, or coat one
side or surface of such paper blanket with a suitable paste or compound of suitable
thickness, such paste being composed of three parts of plaster of Paris, which have
been thoroughly mixed or incorporated with one part of ordinary glue which has
been heated to a semi-liquid state, such blanket is then wrapped or placed around,
and caused to adhere to the periphery of the cylinder of a suitable printing machine
by the said compound.
After the said litho' stone or zinc plate having water-proofed raised prominences
upon its surface has been attached or secured to the bed of such cylinder
printing machines, I form a matrix in the aforesaid blanket surrounding such

page_text: cylinder from such litho' stone or zinc plate, before the paste or compound which
causes such paper blanket to adhere to the periphery of such cylinder has set or
become hard, so that the indentations formed in the outer surface of the said
blanket will be in register with the prominences or raised portions on the said
litho' stone or zinc plate.
The matrix thus formed in such blanket being reverse to the old method, in
which the prominences are upon the covering around the cylinder, and the
indentations or matrix of same are cut or incised, or eaten by a suitable acid or
acids into the litho' stone or zinc plate.
After such covering around the cylinder in which the matrix is formed by my
improved method has become set and sufficiently hard, illustrated sheets which it is
desired to emboss are one a a time run around such matrix upon such cylinder in
the ordinary way of printing in such cylinder printing machines, so that the back of
each sheet to be indented will as such machines are operated come into contact
with the prominences
or raised portions on the surface of such litho' stone or zinc
plate, and be forced or depressed by such raised portions on the litho' stone or zinc
plate into the indentations of the matrix formed in the covering around such
cylinders, so that prominences or raised portions of suitable shape, and height or
heights will be made in desired positions on the illustrated side of such sheets, or
on one side of plain or blank sheets.
I would have it understood that I do not confine myself to the proportions of the
ingredients herein mentioned of which the pastes or compounds used are composed,
as such proportional quantities may be varied without deviating from the essence of
my invention.
Embossing by means of litho' stones, or zinc plates, and matrices fornied
therefrom in the manner herein described being less costly and more effective, than
by litho' stones, and matrices formed in the ordinary way.
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 ;-
1. The method of modelling in relief upon, or raising prominences upon litho'
stones or zinc plates by first delineating a pattern, picture or design by any ordinary
method of drawing upon such stones or plates, then painting by brush, pencil or
other suitable means in suitable positions, and layer upon layer on the surface of
such litho' stone or zinc plate within or about the lines indicating the pattern,
picture or design, a semi-fluid compound or paste (consisting of three parts of
carbonated lime, two parts of liquid gum, and one part of raw white-part of egg)
until the desired height or heights of the several excresences or prominences have
been attained, and when such raised surfaces are sufficiently dry and hard,
brushing over or coating same with white spirit varnish to render such raised
portions waterproof.
Such prepared litbo' stones or zinc plates after being attached or secured to the
bed of a suitable printing machine being operated or used to form a matrix of such
prominences in the outer surface of a paper or other suitable blanket which is
caused to adhere to the periphery of the cylinder of such printing machines by a
compound or paste (consisting of three parts of plaster of Paris mixed with one
part of glue which has been heated till liquid) and whilst such compound is in a
plastic condition.
Litho' stones or zinc plates, and the matrices formed from such stones or plates
in the manner described being used for embossing plain, printed, and lithographed
illustrated sheets in the manner substantially herein set forth.
2. The method of modelling in relief upon, or raising prominences in
any suitable
position, and of suitable height or heights upon lithographic stones, and zinc plates,
by first delineating a pattern, picture or design upon a suitable litho' stone or zinc
plate, then laying or painting by brush, pencil or other suitable means on the
surface of such stone or zinc plate layer upon layer of a semi-fluid compound or

page_text: paste (consisting of carbonated lime, liquid gum, and raw white of egg in suitable
proportions) in suitable positions within or about the lines indicating the pattern,
picture or design until the desired height or heights of the several excresences or
prominences have been attained, and when such raised surfaces are suffiently dry
and hard, brushing over or coating same with white varnish, or other suitable
varnish to render such raised portions waterproof.
Such prepared litho' stones or zinc plates after being attached or secured to the
bed of a suitable printing machine being operated or used to form a matrix of such
prominences in the outer surface of a paper blanket, or the like suitable covering
which is caused to adhere to the periphery of the cylinder of such printing
machines by a paste or compound, (consisting of plaster of Paris and liquid glue)
such matrix being formed in such blanket or covering whilst such paste or compound
is in a plastic condition.
Litho' stones or zinc plates, and the matrices formed from such stones or plates
in the manner described, being used for embossing plain, printed and lithographed
illustrated sheets as herein substantially described and set forth.
3. The method of modelling in relief upon, or raising prominences of suitable
height or heights upon litho' stones, and zinc plates by means of any suitable paste
or compound, and forming matrices therefrom in the outer surface of a paper
blanket, or the like suitable covering, which covering is caused to adhere to the
periphery of the cylinder of such printing machines by means of any suitable
compound or paste, such litho' stones, or zinc plates, and the matrices formed
therefrom being used in such printing machines for embossing plain, printed and
lithographed illustrated sheets in the manner, and for the purpose as herein
substantially described and set forth.
