Improvements in the Manufacture of Figured Double Pile Fabrics.
I, JOSÉ REIXACH, Managing Director of Lister & Co., Limited, of Manningham
Mills, Bradford, in the County of York, do hereby declare the nature of this inven-
tion to be as follows:-
The object of this invention is to produce a figured pile fabric of two or more
colours by a Jacquard machine such for example as that described in Specification
No. 19444 of 1896 or by that described in No. 28731 of 1897 when weaving together
two pieces face to face with two shuttles thrown simultaneously, in such a manner
that the figure or design is caused to stand out prominently on the ground and
produce a bold effect.
To effect this I employ preferably 4 colours of pile three colours of a bright fibre
such as silk for the design or figure and one colour of a duller fibre such as cotton
for the ground. By means of the Jacquard I form a double pile fabric in which
wherever it is desired to form the figure or design one of the colours of the silk
fibre is caused to cross between the two pieces and the remaining silk pile threads
and also the cotton or duller pile threads are caused to weave into the ground of the
top and bottom pieces and to cover up the back of those threads which are making
pile and so prevent them from being pushed out from the face. When it is desired
to form the ground pile, the cotton or duller fibre is crossed between the top and
bottom pieces and the silk or bright threads are used to cover up the back of the
cotton threads which are making pile.
In order to avoid the pile tufts forming lines lengthwise, when four colours are
employed, instead of the four colours lying in one dent as is usual along with two
warps for the top and two warps for the bottom piece, double the usual number of
warp threads and a reed with double the usual number of dents are employed and
2 pile threads with two warps for the top and two warps for the bottom piece are
drawn through one dent and the other two pile threads and two warps for the top
and two warps for the bottom piece are drawn through the adjacent dent.

and ascertained in and by the following statement:
The object of this invention is to produce a figured pile fabric of two or more
colours by a Jacquard machine such for example as that described in Specification
No. 19444 of 1896 or by that described in No. 28731 of 1897 when weaving together
two pieces face to face with two shuttles thrown simultaneously, in such a manner
that the figure or design is caused to stand out prominently on the ground and
produce a bold effect.
To effect this I employ preferably 4 colours of pile three colours of a bright fibre
such as silk for the design or figure and one colour of a duller fibre such as cotton
for the ground. By means of the Jacquard I form a double pile fabric in which
wherever it is desired to form the figure or design one of the colours of the silk
fibre is caused to cross between the two pieces and the remaining silk pile threads
and also the cotton or duller pile threads are caused to weave into the ground of the
top and bottom pieces and to cover up the back of those threads which are making
pile and so prevent them from being pushed out from the face. When it is desired
to form the ground pile, the cotton or duller fibre is crossed between the top and
bottom pieces and the silk or bright threads are used to cover up the back of the
cotton threads which are making pile.
In order to avoid the pile tufts forming lines lengthwise, when four colours are
employed, instead of the four colours lying in one dent as is usual along with two
warps for the top and two warps for the bottom piece, double the usual number of
warp threads and a reed with double the usual number of dents are employed and
2 pile threads with two warps for the top and two warps for the bottom piece are
drawn through one dent and the other two pile threads and two warps for the top
and two warps for the bottom piece are drawn through the adjacent dent.
The drawing annexed shews the method of weaving in, the different pile threads.
A is the pile thread of a dull fibre such as cotton. BCD are the silk pile threads.
When the pile thread A is crossing between the two pieces to make pile and form
the ground of the design in both pieces the silk threads C and D are woven into the
ground of the top piece and are passed over the backs of the same picks of weft
viz. 1, 3, 5, 7 as the pile thread A while the silk thread B is similarly woven into
the back of the bottom piece.
Similarly when either one or the other of the other pile threads B, C, D is crossing
between the two pieces to make pile the remaining pile threads are caused to weave
into the ground of the top and bottom pieces and to cover up the back of those
threads which are making pile.
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 manufacture of double pile fabrics woven face to face by two shuttles
thrown simultaneously with the pile formed in four colours by means of Jacquard
machines such as described in the Specifications of Patents Nos. 19444/96 or 28731/97,
one colour for the ground work of the design being of cotton or other dull fibre
and the remaining three colours being of silk or other bright fibre.
2. The manufacture of figured double pile fabrics in four different colours sub-
stantially in the manner herein before described.
