PROVISIONAL SPECIFICATION.
Improvements in Cut Pile Fabrics and in the Methods of Producing
the same.
I, GUSTAVUS ADOLPHUS JOHN SCHOTT of West End Mills, Bradford in the
County of York, Manufacturer, do hereby declare the nature of this invention to
be as follows :-
My invention relates to cut pile fabrics and more particularly to that class
which have cut pile on both sides of the cloth, similar to the double pile fabrics
described in the Specification of Letters Patent, which were granted to me under
date of Aug. 20th 1989 and numbered 13,082; but my present invention refers to
fabrics the cut pile of which is produced by the warp, and which may be produced
either by the pilew.rp being woven over wires and then cut, or by weaving two
pieces face to face, which are severed by inserting a knife between them, and cutting
the pilewarpthreads which unite them."
As is well known such fabrics are woven with two warps, one for forming the
pile, and the othe. for forming the groundwork of the piece by being interwoven.
with the weft. The last mentioned warp I call the binding warp, and I will now
describe a way of producing the double pile fabric.
"
I proceed the ordinary manner of weaving a onesided pile fabric with three
picks of weft for each line or race of warppile, which interlace with the binding
warp and so bind in the pilewarp as usual. But I add a fourth pick, which I
call the r rn pick and for which the whole binding warp is lifted to the top of
the shed, whilst the whole of the pile warp remains in the bottom of the shed.
Consequently the said return pick comes to lay in the woven piece, between the
binding warp which is above it and the pilewarp which is below it, without being
interlaced with either of them and can after the pile is cut by any of the ordinary
methods be easily detached or drawn out from the back of the woven piece in such
a manner, that in being drawn out it carries with it that portion of the cut pile,
which has been passed under it as above described, the said cut pile warp threads
being drawn from the face of the cloth through the ground, which as before men-
tioned has been formed by the interlacing of the binding warp with the ordinary
weftpicks, to the back of the cloth, upon which they form a cutpile similar to.
that which is left on the face of the cloth.
It will be understood that at the time of and so far as the cutting of the pile is
concerned, the piece is practically an ordinary piece having pile on the face only.
It is transformed into a double cut pile fabric, that is to say, into a fabric having
cutpile on both sides, after the cutting process has been performed, by transferring
part of the cut pile from the face to the back of the fabric in the manner and by
the means described. I may introduce variations in the method of weaving,
arrangement, combination and manner of binding or interlacing the binding warp,
pilewarp, and weft, the essential feature of my process being that the whole of the
warppile is cut on the face of the cloth, and a portion of the cut pile passed after
the cutting to the back of the fabric in order to form a cut pile thereon.
Dated this Seventeenth day of January 1891.

the same.
I, GUSTAVUS ADOLPHUS JOHN SCHOTT of West End Mills, Bradford in the
County of York, 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 cut pile fabrics and more particularly to that class which
have cut pile on both sides of the cloth, similar to the double pile fabrics described
in the Specification of Letters Patent, which were granted 'to me under date of
Aug. 20th 1889 and numbered 13082; but my present invention refers to fabrics
the cut pile of which is produced by the warp, and which may be produced either
by the pilewarp being woven over wires and then cut, or by weaving two pieces
face to face, which are severed by inserting a knife or 'knives between them, and
cutting the pilewarpthreads which unite them, in any convenient known method.
As is well known such fabrics are woven with 'two warps, one for forming the
pile, and the other for forming the ground work of the piece by being interwoven
with the weft. The last mentioned warp I call the binding warp, and I will now
describe a way of producing the double pile fabric, reference being made to the
accompanying drawings.
comes
I proceed in the ordinary manner of weaving a onesided pile fabric with three
picks of weft for each line or race of warppile, which interlace with the binding
warp and also bind in the pilewarp as usual. These three weft picks are shewn
shaded in the accompanying drawings Fig. 1 & 2 and marked " 1, 2 & 3." But
I add a fourth pick, "d" Fig. 1 & 2 which I call the return pick and for which
the whole binding warp shewn in dotted lines and marked "a 1 & 2" in Fig. 1 & 2
is lifted to the top of the shed, whilst the whole of the pile warp "b" Fig. 1 & 2
remains in the bottom of the shed. Consequently the said return pick "d"
to lay in the woven piece, between the binding warp "a 1 & 2" which is above it
and 'the pilewarp "6" which is below it and can after the pile is cut by any of the
ordinary methods be easily detached or drawn out by hand from the back of the
woven piece in such a manner that in being drawn out it carries with it those
sections of the cut pile, which 'have been passed under it as above described, and
which are marked "1" in Figs. 1 & 2, the said cut pile warp threads or
sections ""being drawn from the face of the cloth through the ground, which
as before mentioned has been formed by the interlacing of the 'binding warp
threads a 1 & 2 with 'the ordinary weftpicks "c," to the back of the cloth, upon
which they 'form a cutpile similar to that which is left on the 'face of the cloth,
as indicated in Fig. 3, in which the binding warp is left out for clearness of illus-
tration and the return pick "d" is eliminated as described. I have shewn the
course of the two'binding warpthreads "a" & "a" in the two separate Figs. '1' & 2
for the sake of clearness, as it might have been confusing to 'have shown them in
one fig. "" and "" denote the pile ends or points as they would appear after
cutting the pile warp thread "6"" as will be readily understood.
It will be understood that up to and during the cutting of the pile the piece is
practically an ordinary piece having pile on the face only. It is transformed
into a double cut pile fabric, that is to say, into a fabric having cut pile on both
sides after the cutting process has been performed, by transferring part of the cut
pile from the face to the back of the fabric in the manner and by the means
described. I may introduce variations in the method of weaving, arrangement,
combination and manner of binding or interlacing the binding warp, pilewarp, and
weft, whereby a variety of effects may be obtained.
The essential feature of my process is that the whole of the warppile which is

page_text: intended to be cut is cut on the face of the cloth and a portion of the cut pile
passed after the cutting to the back of the fabric in order to form a cut pile thereon.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. The method of producing double faced warp pile fabrics by pulling portions
of the cut pile from the face of the cloth, through the ground or body of the cloth,
to the back of the cloth, substantially as set forth and indicated.
2. Weaving a cut warp pile fabric with pile on one side and with an additional
weftpick "d," cutting the pile and transferring a portion of it to the other side of
the fabric by pulling out the weftpick "d," in the manner substantially as set forth
and indicated.
