PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Pile Fabrics.
We, GEORGE PRIESTLEY and FREDERICK PRIESTLEY, of the firm of George
Priestley & Co., Mount Street Shed, Leeds Road, Bradford in the County of
York, Manufacturers, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in the manufacture of pile fabrics and its
primary object is to produce a double faced pile fabric that is a fabric having pile
on both sides or faces.
For this purpose we weave three fabrics together in a somewhat similar manner
to the ordinary double pile fabrics and sever the pile in the same way to separate
the fabrics thus producing a central fabric having pile on both sides and at the same
time two ordinary pile fabrics with pile on one side only.
The pile warp may be so interwoven with the foundation of the central fabric as
to form what is known as either fast or loose pile. In the latter case the pile warp
is preferably interwoven between the foundation or backing of the outer fabrics and
the foundation of the inner fabric in such a manner that the outer fabrics are
similar to a fast pile Utrecht velvet whilst the pile is simply passed round every
alternate pick in the central fabric from both sides that is to say from both of the
outer cloths.
To produce a fast pile double faced fabric we preferably interweave the pile warp
with the three fabrics in such a manner that in each case as the pile is crossed from
one fabric to the other that is to say from the central to the outer fabrics and
vice versa it is passed behind one pick over two picks and behind a fourth pick
before it again crosses to the other fabric.

Improvements in the Manufacture of Pile Fabrics.
We, GEORGE PRIESTLEY and FREDERICK PRIESTLEY, of the firm of George
Priestley & Co., Mount Street Shed, Leeds Road, Bradford, in the County of York,
Manufacturers, 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 :-
This invention relates to improvements in the manufacture of pile fabrics and its
primary object is to produce a double faced pile fabric that is a fabric having pile
on both sides or faces.
For this purpose we weave three fabrics together in a somewhat similar manner
to the ordinary double pile fabrics and sever the pile in the same way to separate
the fabrics thus producing a central fabric having pile on both sides and at the same
time two ordinary pile fabrica with pile on one side only.
The pile warp may be so interwoven with the foundation of the central fabric as
to form what is known as either fast, or loose pile. In the latter case the pile warp
is preferably interwoven between the foundation or backing of the outer fabrics and
the foundation of the inner fabric in such a manner that the outer fabrics are
similar to a fast pile Utrecht velvet whilst the pile is simply passed round every

page_text: alternate pick in the central fabric from both sides that is to say from both the
outer cloths.
To produce a fast pile double faced fabric we preferably interweave the pile warp
with the three fabrics in such a manner that in cach case as the pile is crossed from
one fabric to the other that is to say from the central to the outer fabrics and
vice versa it is passed behind one pick over two picks and behind a fourth pick
before it again crosses to the other fabric.
In the accompanying drawing forming a part of this Specification Figure 1,
represents a longitudinal sectional view or diagram illustrating the manner we
preferably interweave the pile to form a triple pile fabric with the central fabric
loose pile. And to avoid confusion the warp and weft threads forming the foundation
of the several fabrics are not shown as they are arranged and interwoven in the
same manner as the foundations of a double pile fabric excepting that there are
three instead of two.
Four pile warp threads are visible in the section respectively numbered 1, 2, 3
and 4 and the threads 2 and 4 are represented by broken lines to more clearly show
that the pile is alternately formed by different threads and for the same reason the
threads 2 and 4 are omitted at one end of the section and the threads 1 and 3 at the
other. It is clearly shown that the pile simply passes round one weft thread a in
the foundation of the central fabric thus forming what is known as a loose pile:
But in the outer fabric the pile from the central fabric is passed behind one weft
thread of the outer fabric then in front of two weft threads and behind a fourth
weft thread in a similar manner to an Utrecht velvet before again passing into the
central fabric.
In Figure 2, which is also a longitudinal section eight pile warp threads are
visible respectively numbered 1, 2, 3, 4, 5, 6, 7, and 8. The threads 5 to 8 forming
the pile in the lower fabric and the underside of the middle fabric are représented
by broken lines to distinguish them from the pile warp in the upper fabric. In this
figure the pile warp is interwoven with the weft threads a so as to form a fast pile
in both the central aud outer fabrics.
We find it more convenient to cut or divide the several fabrics after they have
been removed from the loom.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare what we
claim is:
1. A pile fabric woven in the above described manner adapted to be divided into
three fabrics that is a central fabric with the pile on both sides and two ordinary
pile fabrics, substantially as herein shown and described.
2. A triple pile fabric having the pile warp interwoven in the manner herein
described and illustrated in the accompanying drawings.
