page_text: Improvements in the Manufacture of Carpets and other Terry
and Cut Pile Fabrics.
I GIULIO MARCHETTI, of Dean Clough Mills, Halifax, in the county of York,
Carpet Manufacturer, 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 :—
My invention relates to an improved manufacture of carpets and other terry
and cut pile fabrics in which the pattern is formed by means of various threads of
different colours, the threads which have to be lifted to form the pattern being
selected by means of a jacquard or other similar machine, as in the case for
example of Brussels and Brussels Velvet carpets.
My invention consists in manufacturing such goods by inserting between the
pile threads, which are selected by the jacquard or other similar machine and are
sometimes lifted to form the pile and sometimes buried in the body of the fabric,
threads which may be either mottled or self-coloured and which are lifted to pass
over every pile wire from one end of the fabric to the other.
The object of my invention is to produce, by the juxta-position of pile threads
which are always lifted to form the pile when a wire is inserted and of pile threads
which are selected by the jacquard or other similar machine and which are
continually changing sometimes being lifted and sometimes being buried in the
body of the fabric as inay be required by the design, a novel kind of fabric and to
give an effect which I term a sheeny or variegated effect.
By means of my invention I am enabled to produce my improved goods at a
less cost than the ordinary Brussels and Brussels velvet carpets and other similar
pile fabrics and at the same time to obtain novel effects of design and variegated
colouring.
Brussels and Brussels velvet carpets and other terry and cut pile fabrics of the
same class have usually been composed of pile warps of worsted or other suitable

page_text: material for forming the face of the cloth and of a binding warp, and in some
cases of a stuffing warp, both of suitable material for forming the back of the cloth,
the face warps and the back warp or warps being bound together by weft of
suitable material.
The threads forming the pile warps have usually been self coloured, although in
certain cases some of them have been either mottled or printed; they have been
wound upon bobbins and arranged upon creels, those of one colour being usually
placed upon one creel.
As is well known to those engaged in the trade in weaving an ordinary five
frame Brussels or Brussels velvet carpet or similar fabric, five pile threads of
different colours have usually been drawn into one dent of the reed; together with
threads of the backing warp, and the pile thread which has been required by the
design has been selected from the five threads by means of the jacquard or other
similar machine.
The threads forming the pile have thus been continually changing according to
the requirements of the design, those not required by the design being buried
in the body of the fabric, whilst those required by the design have been raised for
the insertion of the pile wire to form the pile: thus the same pile thread has
never been raised for the insertion of every successive wire, with the exception of
certain pile threads which have been used for formning the ground of the design or
for dividing or marginal lines in stair carpets or in the borders of carpets or other
similar pile fabrics, and which have been lifted for the insertion of every successive
pile wire from the beginning to the end of the design.
In carrying out my invention instead of drawing into each dent of the reed five
pile threads of different colours as is usual in the case of a five frame Brussels or
Brussels velvet carpet or other pile fabric of the same class I draw into every
alternate dent of the reed five pile threads and the usual backing threads, and in
the other dents of the reed I draw only one pile thread and the usual backing
threads and in addition a sufficient number of stuffing threads of suitable material
to maintain the even character of the fabric.
I so arrange the cards which act upon the jacquard or other similar machine
that where there is only one pile thread in a dent, it is lifted, by means of the
Jacquard or other similar machine, for the insertion of every pile wire, but where
there are more than one of the pile threads in a dent, one is selected out of each
dent by the jacquard or other similar machine, as may be required by the design
and is lifted for the insertion of a pile wire.
Although I have spoken of filling the dents of the reed with the pile threads
that work one in a dent and the usual pile threads alternately, I do not confine
myself exclusively to this arrangement as I find the pile threads that work one in
a dent can be separated by more than one dent filled with the ordinarily working
pile threads and still produce the desired effect which I term a sheeny or
variegated effect.
The mottled pile threads and the self coloured pile threads are manufactured in
the usual manner which is well known and are composed of any suitable matérial
or materials. The number of threads of each colour forming one complete mottled
pile thread may be varied at will. By my improved mode of manufacture it will
be obvious that I am enabled to produce many different effects of colour without
altering the pile threads, which work five in a dent of the reed in the usual
manner, simply by varying the colours of the mottled or self coloured pile threads
which work one in a dent of the reed; and by inserting the mottled or self-
coloured pile threads as above described I am enabled to produce with economy
improved carpets and like goods in great variety. Although I have spoken of
having five of the ordinarily working pile threads in one dent of the reed, it will
be obvious that this number can be varied according to the number of frames
required for the production of any desired design.

page_text: 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
1. The method herein described of manufacturing my improved carpets and
other terry and cut pile fabrics by the insertion between the ordinarily working
pile threads selected by a jacquard or similar machine of mottled or self-coloured
pile threads which work one in a dent of the reed and are lifted for every insertion
of the pile wires in the manner and for the purposes substantially as described.
2. The manufacture and use of my hereinbefore described improved carpets and
other terry and cut pile fabrics.
