I, WILLIAM SCOTT MORTON, of Albert Works, Tynecastlo, Edinburgh, in the
County of Mid Lothian, North Britain, Decorative Architect, do hereby declare
the nature of my Invention for "IMPROVEMENTS IN EMBOSSING CANVAS FOR
DECORATING WALLS OR OTHER SURFACES, AND IN APPARATUS THEREFOR
to be as
follows:-
My said Invention has for its object to improve and render more expeditious
and economical the process whereby canvas is embossed to serve for decorating
walls and other surfaces.
In carrying out the Invention plates of metal or other suitable material are
formed by casting from patterns or by otherwise shaping them so as to serve as
moulds for producing raised ornamental devices on the canvas. The canvas is first
prepared by boiling or steeping in boiling water and subsequently steeping in hot
size and wringing or squeezing out to a suitable extent. The prepared canvas is
laid on the mould plato the side which is down on the plate being that which is to
form the outer surface, and it is worked into all the cavities and intricacies of the
mould by means of brushes or beaters. The deeper cavities which are to form the
more prominent parts of the finished canvas are packed on the back, which is
uppermost when the canvas is being moulded, with paper pulp, papier maché, or
other suitable substance; after which a paper backing is pasted on and made closo
by beating with brushes or beaters. A thick layer of dry sawdust or similar
material is next laid over the backing and pressure is applied by means of a screw
press or otherwise. The sawdust is then by preference removed, and the mould
plate with the canvas on it is placed on a metal chest or casing which is heated by
steam or in any other convenient way. After the heat has acted for a short time
fresh dry sawdust is laid over the back of the canvas and pressure is again applied
and is continued along with the application of heat until the canvas becomes quite
dry. The canvas is finally removed from the mould plate and the latter is cooled
in any convenient way to prepare it for being used to mould a fresh portion of
canvas.
In some cases the mould may be made in the form of a hollow plate or shallow
box the top surface being the inould surface and it may be heated by passing hot
water or steam through it and cooled by passing cold water through it.

I, WILLIAM SCOTT MORTON, of Albert Works, Tynecastle, Edinburgh, in the
County of Mid Lothian, North Britain, Decorative Architect, do hereby declare
the nature of my said invention for IMPROVEMENTS IN EMBOSSING CANVAS FOR
DECORATING WALLS OR OTHER SURFACES, AND IN APPARATUS THEREFOR," and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, that is to say :-
My said Invention has for its object to improve and render more expeditious and
economical the process whereby canvas is embossed to serve for decorating walls
and other surfaces.
In carrying out the Invention plates of metal or other suitable material arc
formed by casting from patterns or by otherwise shaping them so as to serve as
moulds for producing raised ornamental devices on the canvas. The canvas is first
prepared by boiling or steeping in boiling water and subsequently steeping in hot
size and wringing or squeezing out to a suitable extent. The prepared canvas is
laid on the mould plate the side which is down on the plate being that which is to
form the outer surface, and it is worked into all the cavities and intricacies of the
mould by means of brushes or beaters. The deeper cavities which are to form the
more prominent parts of the finished canvas are packed on the back, which is
uppermost when the canvas is being moulded, with paper pulp, papier maché, or
other suitable substance; after which a papor backing is pasted on and made close
by beating with brushes or beaters. A thick layer of dry sawdust or similar
material is next laid over the backing and pressure is applied by means of a screw
press, or otherwise. The sawdust is then by preference removed, and the mould
plato with the canvas on it is placed on a metal chest or casing which is heated by
steam or in any other convenient way. After the heat has acted for a short time
fresh dry sawdust is laid over the back of the canvas and pressure is again applied
and is continued along with the application of heat until the canvas becomes quite
dry. The canvas is finally removed from tho mould plate and the latter is cooled
in any convenient way to prepare it for being used to mould a fresh portion of
canvas.
In some cases the mould may be made in the form of a hollow plate or shallow
box the top surface being the mould surface and it may be heated by passing hot
water or steam through it and cooled by passing cold water through it.
In practising my Invention I find that in many cases the second application of
pressure hereinbefore described may be dispensed with, and in some cases little or
*no pressure requires to be applied after the canvas has been put in contact with all
parts of the moulding surfaces by means of brushes or beaters.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to bo performed, I declare that what
I claim is
1. The embossing of canvas for decorating walls or other surfaces by means
of plates having suitable moulding surfaces, the canvas in a prepared or sized

page_text: condition, being applied to the moulding surfaces by means of brushes or beaters,
and after backing being heated whilst still in contact with the moulding surfaces,
substantially as herein before described.
2. The combined use of moulding plates and heated metal casings substantially
as and for the purposes herein before described.
3. The making of the mould in the form of a hollow plate or shallow box
capable of being heated by hot water or steam and of being cooled by cold water,
|substantially as and for the purposes hereinbefore described.
