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 this Invention to be as follows, that is to say :-
This Invention has for its object to improve and cheapen the manufacture of
embossed canvas for decorative purposes; and in carrying it out there is provided
a hollow metal cylinder, carried horizontally in bearings in a suitable frame, and
having a hollow shaft to which there is connected through a stuffing box a
stationary pipe for the admission of steam or other hot fluid for heating the
cylinder. The framing is also made with bearings for a roller carrying the canvas
which is to be embossed such canvas having had paper backing applied to it by
preference in. the manner described in the Specification of Patent N° 15162 of 1884.
The hollow cylinder has indented in its surface the ornamental devices which
are to appear raised on the canvas, the surface being formed by casting or in any
other suitable manner and being in the shell of the cylinder itself or in an outer
shell or segments fixed on the cylinder. The backed canvas is drawn off its
carrying roller, and a portion of it being placed on the indented cylinder it is
worked by brushes or pads so as to become closely applied to the indentations
being drawn or gathered into such indentations as are of. extra depth. The heat
of the cylinder causes the canvas to rapidly stiffen and dry so as to retain the
embossed effect; and as the embossing of each portion proceeds the cylinder is
turned round to draw on it more of the canvas, and the embossed portions pass off
from it at the same time. "The brushes or pads may be worked by hand, or by
apparatus of the
he kind described in the Specification of Patent N° 2420 of 1882.

Walls and other Surfaces.
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 this invention 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:-
This Invention has for its object to improve and cheapen the manufacture of
embossed canvas for decorative purposes; and in carrying it out there is provided
a hollow metal cylinder carried horizontally in bearings in a suitable frame, and
having a hollow shaft to which there is connected through a stuffing box a
stationary pipe for the admission of steam or other hot fluid for heating the
cylinder which has the ornamental devices, which are to appear raised on the
canvas, formed in intaglio in the shell of the cylinder itself or in an outer shell or
segments fixed on the cylinder. The framing is also made with bearings for a
roller carrying the canvas which is to be embossed and such canvas has paper
backing applied to it by preference in the manner described in the Specification of
Patent No 15162 of 1884. The canvas is drawn off its carrying roller and passing
over the indented cylinder it is worked by brushes or pads so as to become closely
applied to the indentations, the heat of the cylinder causing the canvas to rapidly
stiffen and dry so as to retain the embossed effect. The brushes or pads may be
worked by hand, or by apparatus of the kind described in the Specification
No 2420 of 1882.
And in order that my said Invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings to
be hereinafter referred to in describing my improved apparatus.
Figure, 1, on the accompanying sheet of drawings is a transverse vertical section
showing the canvas as passing round the embossing cylinder and receiving the
prepared backing paper in a machine worked by power. Figures, 2, and 3, are a
longitudinal section and a side elevation respectively showing the embossing
cylinder and means for heating the same; and figure, 4, is an end elevation similar
to figure, 1, but for a hand machine. In these drawings the same reference
numerals are used to mark the same or like parts wherever they are repeated.
In carrying out my Invention there is provided a hollow metal cylinder, 5,
carried horizontally in bearings, 6, in a frame, 7, and having hollow journals, 8,
through one end of which a stationary pipe, 9, passes, for the admission of steam
or other hot fluid for heating the cylinder, 5, the end of the pipe, 9, being inserted
through a stuffing box and gland, 10. A small pipe, 11, passes through the other
hollow journal, 8, through which pipe, 11, any water due to condensation of the
steam is forced out by the pressure in the cylinder, 5. This hollow cylinder, 5,
has indented in its surface the ornamental devices which are to appear raised on
the canvas, the surface being formed by casting, or in any other suitable manner,
and being in the shell of the cylinder itself or in an outer shell or segments fixed
on the cylinder,

page_text: The framing, 7, is also made with bearings, 12, for a roller, 13, carrying the
canvas to be embossed; and the canvas being drawn off its carrying roller, 13, and
a portion of it being placed on the indented cylinder, 5, it is worked by brushes or
pads so as to become closely applied to the indentations being drawn or gathered
into such indentations as are of extra depth. The heat of the cylinder causes the
canvas to rapidly stiffen and dry whilst being thus operated on so as to retain the
embossed effect. As the embossing of each portion proceeds, the cylinder, 5, is
turned round to draw on it more of the canvas and the embossed portions pass
further round the cylinder, 5, to receive a backing of paper which is applied to it
by preference in the manner described in the Specification of Patent No 15162 of
1884 and as shown in figures, 1, and 4, of the accompanying drawings. The
roller, 14, with the pasted paper and a waterproof sheet on it is placed in connection
with the embossing cylinder, 5, and another roller, 15, is also provided on which
the waterproof sheet is wound as it unwinds along with the paper whilst the paper
is being applied to the back of the embossed canvas. The backed canvas moves
some distance further in contact with the cylinder, 5, so as to be further heated
and dried, and it then leaves the cylinder and passes over a guide roller, 16.
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:-
In apparatus for embossing canvas, the application of a hollow metal embossing
cylinder arranged to be heated by steam or other hot fluid substantially as and for
the purposes hereinbefore described.
