Year: 1884

page_text: We, WILLIAM SCOTT MORTON, of Albert Works, Tynecastle, Edinburgh, in the
County of Mid Lothian, North Britain, Decorative Architect, and JOHN MORTON,
of the same place, Engineer do hereby declare the nature of our Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF EMBOSSED CANVAS FOR DECORATING.
WALLS OR OTHER SURFACES, AND IN APPARATUS THEREFOR" to be as follows:-
:-
Our said Invention relates to the process of manufacturing embossed canvas for
decorating walls and other surfaces wherein a cylinder or roller is used for the
embossing operation the surface of such cylinder being made a counterpart of the
intended embossed work, and it consists in preparing and applying the paper
backing in an improved manner.
In carrying out the Invention a special long table is provided on which the
paper backing is laid to have the paste applied to it by means of brushes. The
paper, having been first moistened by steeping in or drawing through hot water,
is laid on a sheet or piece of waterproof fabric which is attached by one end to a
frame fitted to slide along guides at the side of the table, the other end of the
sheet being fixed to a roller at one end of the table. When the paste has been
applied the roller is turned to wind up the waterproof sheet and the paper, no
strain being applied to the latter, whilst the sliding frame prevents uneven winding.
The waterproof sheet prevents the paste from touching the back of the paper and
when rolled up keeps the paper and paste in a proper moist condition until applied
to the embossed canvas.
The roller with the pasted paper and waterproof sheet on it, is placed in
connection with the embossing machine, and another roller is also provided on
which the waterproof sheet is wound as it unwinds along with the paper whilst
the latter is being led into the machine and applied to the back of the embossed
canvas. To avoid straining the paper a suitable band which is wound upon a pulley
on the shaft of the roller is drawn by means of the embossing cylinder and a pulley
pressing the band against the cylinder, and this band turns the roller on which the
paper is wound exactly as if the roller were turned by drawing off the paper.
Dated this 18th day of November 1884.

page_text: Improvements in the Manufacture of Embossed Canvas for
Decorating Walls or other Surfaces, and in Apparatus
therefor.
We, WILLIAM SCOTT MORTON, of Albert Works, Tynecastle, Edinburgb, in the
County of Mid Lothian, North Britain, Decorative Architect, and JOHN MORTON,
of the same place, Engineer, do hereby declare the nature of our said invention
for "IMPROVEMENTS IN THE MANUFACTURE OF EMBOSSED 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:—
Our said Invention relates to the process of manufacturing embossed canvas for
decorating walls and other surfaces, wherein a cylinder or roller is used for the
embossing operation, the surface of such cylinder being made a counterpart of the
intended embossed work, and it consists in preparing and applying the paper
backing in an improved manner.
A sheet of explanatory drawings is hereunto appended to be hercinafter referred
to in describing our improved process and apparatus. Figure, 1, of the drawings
is a plan of a long table used in carrying out our Invention; figure, 2, is a vertical
section of a trough used for moistening the backing paper; figure, 3, is a side
.elevation (partly broken away) of the table shown in figure, 1, figure, 4, being a
corresponding end elevation; figures, 5, and 6, are end and side elevations showing
apparatus used in applying the prepared backing paper in a machine worked by
power; and figure, 7, shows a modification suitable for a machine worked by hand.
In these drawings the same reference numerals are used to mark the same or like
parts wherever they are repeated.
In carrying out our Invention a special long table, 11, figures, 1, 3, and 4, is
provided on which the backing paper is laid to have the paste applied to it by
means of brushes. The paper is first moistened by steeping in hot water, or by
drawing it through hot water by apparatus such as is shown in figure, 2, this
apparatus comprising a trough, 12, for the hot water and fitted with bearings for
two rollers, 13, 14, and the paper being wound off one roller and upon the other.
The moistened paper is laid on a sheet or piece, 15, of waterproof fabric which is
attached by one end to a frame, 16, fitted to slide along guides at the sides of the
table, 11, the other end of the sheet, 15, being fixed to a roller, 17, at one end of
the table. When the paste has been applied the roller, 17, is turned to wind up
the waterproof sheet, 15, and the paper, no strain being applied to the latter,
whilst the sliding frame, 16, prevents uneven winding. The waterproof sheet, 15,
prevents the paste from touching the back of the paper, and when rolled up keeps
the paper and paste in a proper moist condition until applied to the embossed
canvas.
The roller, 17, with the pasted paper and waterproof sheet, 15, wound upon it
is placed in connection with the embossing machine in the manner indicated in

page_text: figures, 5, and 0, and another roller, 18, is also provided upon which the waterproof
sheet, 15, is wound as it unwinds from the roller, 17, along with the paper whilst
the latter is being led into the machine and applied to the back of the embossed
canvas. The rollers, 17, 18, are placed with their journals or end spindles in
grooves in a pair of brackets, 19, (one bracket being supposed to be removed in
figure, 5,) and these brackets can be fixed in different positions on horizontal
bars, 20, forming part of the framing of the machine, to suit the size of the
embossing cylinder, 21, which varies in different cases. The upper roller, 18, rests
upon the lower roller, 17, and when the paper in being drawn by the embossing
machine unwinds from the lower roller, 17, this roller in turning acts frictionally
so as turn the upper roller, 18, and thereby makes the latter wind up the water-.
proof sheet, 15. The backing paper ordinarily used is found to be strong enough
to stand the strain of drawing it off the roller, 17, as described; but if it is in any
case found desirable to avoid straining the paper, a suitable band may be wound
on a pulley on the shaft or spindle of the roller, 17, and may be drawn by means
of the embossing cylinder, 21, and a pulley pressing the band against the cylinder;
and such band would turn the roller, 17, on which the paper is wound exactly as if
the roller were turned by drawing off the paper.
In the power-driven machine the roller, 17, 18, have to be placed to one side as
shown in figure, 5, because the stamps or brushes which press the canvas into the
hollows of the embossing cylinder, 21, act vertically down upon the top of the
cylinder. In a hand-worked machine however (of the kind having an embossing
cylinder, 21,) the rollers, 17, 18, can be placed directly over the cylinder, 21, as
shown in figure, 7. The journals or end spindles of the rollers, 17, 18, are retained
in slots formed in a pair of blocks, 22, (of which one is supposed to be removed in
figure, 7,) and these blocks, 22, can be adjusted vertically between.guides, 23, to
suit cylinders, 21, of different sizes. A pin, 24, entered through one of a number
of holes formed in each pair of guides, 23, serves for supporting each block, 22, in
the required positions.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
1. The improvements in the manufacture of embossed canvas consisting in
applying the paper backing by unwinding it from a roller upon which it has been
wound after being prepared with paste along with a waterproof sheet substantially
in the manner hereinbefore described.
2.-The combination of apparatus for preparing the paper backing with paste,
for winding it on a roller along with a waterproof sheet, and for unwinding it and
at the same time rewinding the waterproof sheet, all substantially as hereinbefore
described.
