Artist, employed by The New Press Printing Company (Hanley) Limited, Hanley,
Staffordshire, do hereby declare the nature of this invention to be as follows:-
-
A new method of embossing paper, boards, leather, tin, and such like substances,
by means of carving a compound mixed and dried, afterwards taking a metal cast
of such carved compound, and putting such cast into a suitable machine and
obtaining a matrix of the metal cast, and afterwards obtaining embossment by
impressing the paper, boards, leather, tin, or like substance by means of a suitable
machine between the matrix and the cast.

A New Method of Embossing Paper, Boards, Leather, Tin, and like
Substances.
We, THE NEW PRESS PRINTING COMPANY (HANLEY), LIMITED, Hanley, Stafford-
shire, Letterpress Printers, Lithographers, &c., and DAVID PRICE, employed by
the said New Press Printing Company Limited, Hanley, Staffordshire, Litho-
graphic 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 our invention has reference to a new or improved method of embossing
coloured, plain, printed or lithographed sheets of paper, cardboard, leather, tin or
similar suitable materials of any suitable thickness, for improving the shape of
and causing illustrations to more accurately represent the article illustrated, the
object of our said invention being to prolong the life of the blocks or dies used,
and permit such blocks to be laid up or stored away till required for use without
depreciation.
In carrying our said invention into practice we first take plaster of Paris and

page_text: liquid gum in suitable proportions which we thoroughly mix together until semi-
liquid by any suitable means in any suitably shaped wood, metallic or other
suitable framing, box or receptacle, we then level or flatten the top surface of
such mixture or compound by any suitable means and allow such compound to
dry or thoroughly set.
We then draw, trace or transfer on the level or flat hard dried upper surface of
such compound the pattern, picture or design required, and afterwards carve or
engrave in, on or within the lines constituting such pattern, picture or design on
the surface of such compound by any suitable appliances any suitable number of
suitably shaped grooves, hollows, concaves or the like of the same or varying sizes
according to the height, depth and extent of the several embossments or pro-
minences required on paper or other material, we then take a suitable quantity
of molten gun-metal, white-metal, lead, type-metal or other like suitable metal or
metallic alloy which we pour on to such plaster block or mould so as to fill the
several grooves or incisions in such plaster mould, such metallic plate, die or block
when sufficiently cool or set and removed from such plaster mould being of any
suitable thickness according to the metal from which it is cast or made and the
material to be embossed with the several required prominences or projections on
its surface.
When required for use we attach or fasten such metallic dies with the projections
or prominences outward to the cylinder of a cylinder printing machine, to the
platten, of a platten letter press printing machine or in or to an embossing or die
stamping machine, then we make a matrix or counterpart of the said several
prominences of or on such metallic dies in paper, card-board, tin or other suitable
material of suitable thickness attached to the bed of the machine used, or attached
or fixed to a wood or other suitable block fastened or fixed to the bed of such
machine.
It will be readily understood that sheets of coloured, plain, printed or litho-
graphed paper, card-board, leather, tin or other material of suitable thickness
which require to be embossed after being placed in such machines and such
machines set in motion or worked, that such sheets will be embossed as they pass
between such metallic dies and their matrices at the several parts required.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
The method of casting or making metallic plates, dies or blocks with pro-
minences or projections on one of their surfaces for use in any suitable machine
for embossing coloured, plain, printed or lithographed sheets of paper, cardboard,
leather, tin or the like similar suitable materials as herein substantially described
and set forth.
Dated this 29th day of April 1898.
