for an Invention of IMPROVEMENTS IN THE PRODUCTION OF PATTERNS UPON
VELVETS AND OTHER CUT PILE FABRICS
PROVISIONAL SPECIFICATION left by the said Dugald Scott at the Office
of the Commissioners of Patents on the 28th December 1883.
DUGALD SCOTT of Manchester, in the County of Lancaster,
"IMPROVEMENTS
"
IN THE PRODUCTION OF PATTERNS UPON VELVETS AND OTHER CUT PILE FABRICS
This invention is a variation or modification of an invention for which Letters
Patent bearing even date herewith, this invention being however only applicable
to cut pile fabrics.
The object of the invention is to dispense with the shearing process and to
produce from a plain cut velvet, or other cut pile fabric, a figured velvet with a
plain ground and a velvet pile pattern similar to what is known as a "Brocade
velvet."
According to this invention I employ the same kind of carved or engraved
rollers or blocks as in the other case, that is with the projecting parts of the said
rollers or blocks corresponding with those parts of the design which are intended
eventually to form the velvet pile pattern, and with these rollers or blocks I press
down or lay the cut pile of the fabric on those parts only which are to form the
pattern, leaving the cut pile standing erect on those portions only which are to
form the ground.
In this case also I sometimes find it sufficient to stamp or press the cut pile
down simply either with or without the application of heat. I prefer, however, to
steam or damp the fabric before stamping or embossing, so that the starch or
adhesive dressing material which has been used in the manufacture or weaving of
the cloth shall cause the laid fibres of the pile to adhere to each other, and to the
back of the cloth (when pressed down by the rollers or blocks) more closely and
firmly than they would otherwise do.

page_text: In cases where the amount of adhesive material in the cloth is not sufficient for
this purpose I apply an additional quantity thereof to the cloth in any suitable
manner.
The stamping or embossing by the rollers or blocks may be done on the face or
on the back of the fabric, but I prefer the latter because in that case those portions
from which the pile is not required to be removed are sunk or pressed in at the
back, leaving the other portions projecting, which greatly facilitates the removal of
the pile therefrom.
Having by these means effectually laid and fixed the pile in those parts which
are intended to form the piled pattern, I prefer to dry the fabric and I then
remove the pile from the other parts by the application to the back of the fabric of
a revolving roller covered with emery or other suitable substance, or by a revolving
or other brush, or by a wire card roller or other similar means; after which I again
raise the pile (by steaming, washing, brushing or otherwise) upon those portions
of the fabric from which it has not been removed, and thus I produce a fabric with
a plain ground and a raised pile pattern similar to what is known as a "Brocade
velvet."

DUGALD SCOTT of Manchester in the County of Lancaster IMPROVEMENTS IN
THE PRODUCTION OF PATTERNS UPON VELVETS AND OTHER CUT PILE FABRICS
This invention is a variation or modification of an invention for which I have
filed an application for Letters Patent N° 5902 bearing even date herewith, this
invention being however only applicable to cut pile fabrics
The object of the invention is to dispense with the shearing process and to
produce from a plain cut velvet, or other cut pile fabric a figured velvet with a
plain ground, and a velvet pile pattern similar to what is known as a Brocade
velvet'
"
According to this invention I employ the same kind of carved or engraved rollers
or blocks as in the other case, that is, with the projecting parts of the said rollers
or blocks corresponding with those parts of the design which are intended eventually
to form the velvet pile pattern, and with these rollers or blocks I press down or
lay the cut pile of the fabric on those parts only which are to form the pattern,
leaving the cut pile standing erect on those portions only which are to form the
ground.
In this case it might also be found sufficient to stamp or press the cut pile down
simply either with or without the application of heat. I prefer however to steam
or damp the fabric before stamping or embossing, so that the starch or adhesive
dressing material which has been used in the manufacture, weaving or dressing of
the cloth shall cause the laid fibres of the pile to adhere to each other and to the
back of the cloth (when pressed down by the rollers or blocks) more closely and
firmly than they would otherwise do.
In some cases, where the amount of adhesive material in the cloth is not sufficient
for this purpose, I apply an additional quantity thereof to the cloth in any suitable
manner.
In most cases I find it best to wash out the old adhesive material and to apply
wax or soap or other suitable substance or composition to the pile, either over its
entire surface or to apply the same to the surface of the embossing roller, in
which case it is only transferred to those parts of the fabric which are to form the
pattern.
The stamping or embossing by the rollers or blocks may be done on the face or
on the back of the fabric: but I prefer the latter, because in that case those
portions from which the pile is not required to be removed are sunk or pressed in
at the back leaving the other portions projecting which greatly facilitates the
removal of the pile therefrom.
Having by these means effectually laid and fixed the pile in those parts which
are intended to form the piled pattern, I then remove the pile from the other parts
by the application to the back of the fabric of a revolving roller covered with
emery or other suitable substance, or by a revolving or other brush, or by a wire
card roller, or other similar means; after which I again raise the pile (by steaming,
washing, brushing or otherwise) upon those portions of the fabric from which it
has not been removed, and thus I produce a fabric with a plain ground and a raised
pile pattern similar to what is known as a "Brocade velvet."
Having now described the nature and object of my said invention and in what
manner the same is to be or may be performed or carried into practical effect, I
wish it to be understood that I claim as my invention the production of patterns
upon cut pile velvets or other cut pile fabrics by stamping embossing or pressing

page_text: down those portions of the pile which are desired to remain and form the pattern,
and then removing the other portions of the pile from the back of the fabric, and
afterwards re-raising those portions of the pile which had previously been laid,
substantially as hereinbefore described.
In witness whereof I the said Dugald Scott have hereunto set my hand and
seal this twenty sixth day of June in the year of our Lord one thousand eight
hundred and eighty four
