PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Figured Woven Fabrics.
We, THOMAS TAYLOR, of Barlow and Jones Limited, of Bolton, in the County
of Lancaster, Manufacturer and JACOB WARBURTON, of 7 Hampden Street,
Bolton aforesaid, Designer do hereby declare the nature of this invention to be as
follows:-
Our invention relates to improvements in the manufacture of coloured woven
figured fabrics for which we obtained Letters Patent numbered 17088 and dated
24th September 1892.
A figured fabric woven according to our said Patent has figures of two or more
different colours or materials upon a self coloured, variegated or tapestry ground
produced by weaving in which one ground pick of weft and one figure pick of weft
for each colour or material are put into every shed of the face warp. This weave
of cloth has a single ground pick of weft to two figure picks of weft and this
proportion is to a certain extent objectionable and expensive as it involves the use
of drop boxes on each side of the loom.
Our present improvements consist in a modification of this proportion when
weaving the cloth illustrated by diagram Fig. 2 of our aforesaid Patent in which
we employ two ground picks of weft and vary the order of shedding as follows:-
The 1st pick is a figure pick. The Jacquard machine is up, and the 1st heald is
raised.
The 2nd and 3rd picks are ground picks. The Jacquard machine is down and
the 1st cumber board is raised the 1st heald remaining up, both picks being in one
shed.
The 4th pick is a figure pick. The Jacquard machine is raised, the 1st heald
remaining up.
The 5th pick is a figure pick. The Jacquard machine remaining up and the
2nd heald being raised.
The 6th and 7th picks are ground picks. The Jacquard machine is down and
the 2nd cumber board is raised the 2nd heald remaining up, both picks being in
one shed.
The 8th pick is a figure pick. The Jacquard machine is raised the 2nd heald
remaining up.
As an alternative, the Jacquard machine may be raised and the respective
cumber board remain down so as to put the extra ground weft pick in the same
shed as a figure pick.
By weaving our improved figured fabric by either of the modes specified we only
require a drop box at one side of the loom and consequently the cost of production
is lessened.

We, THOMAS TAYLOR, of Barlow and Jones Limited, of Bolton, in the County
of Lancaster, Manufacturer, and JACOB WARBURTON, of 7 Hampden Street,
Bolton aforesaid, Designer, 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 :-
Our invention relates to improvements in the manufacture of coloured woven
figured fabrics for which we obtained Letters Patent numbered 17088 and dated
24th September 1892.
A figured woven fabric according to our said Patent has figures of two or more
different colours or materials upon a self coloured, variegated or tapestry ground
produced by weaving in which one ground pick of weft and one figure pick of weft
for each colour or material are put into every shed of the face warp. This weave
of cloth has a single ground pick of weft to two figure picks of weft and this
proportion is to a certain extent objectionable and expensive as it involves the use
of drop boxes on each side of the loom.
Our present improvements consist in a modification of this proportion, when
weaving the cloth illustrated by Diagram 2 of our aforesaid Patent, in which we
employ two ground picks of weft and vary the order of shedding as illustrated on
the accompanying sheet of diagrams in which-
Figure 1 is a diagram representing the order of shedding when weaving our
improved figured fabric, and Fig. 2 is a similar diagram illustrating an alternative
method of weaving the same.
In the diagrams,-a designates the first heald and the second heald through
which the face warp is drawn, the ground warp is drawn into a Jacquard harness
which is drawn into two pressing cumber boards, lettered c, d, the numerals 1, 2, 3,
4, 5, 6, 7, and 8, give the order of the successive picks of weft, and the crosses on
the diagrams indicate the order in which the warp threads are raised.
The first pick is a figure pick. The Jacquard machine is up and the 1st heald a
is raised while a pick of coloured figure weft is thrown into this shed.
The second and third picks are ground picks. The Jacquard machine is down
and the 1st cumber board c is raised, the 1st heald a remaining up, while the two
picks of ground weft are thrown into this shed.
The fourth pick is a figure pick. The Jacquard machine is raised, the
1st heald a remaining up, while a pick of the second colour figure weft is thrown
into this shed.
The fifth pick is a figure pick. The Jacquard machine remaining up, the
1st heald a being lowered and the second heald being raised while a pick of the
second colour figure weft is put into this shed.
The sixth and seventh picks are ground picks. The Jacquard machine is down,
and the second cumber board d is raised the second heald 6 remaining up while the
two picks of ground weft are thrown into this shed.
The eighth pick is a figure pick. The Jacquard machine is raised, the
2nd heald & remaining up while a pick of the first colour figure weft is put into
this shed.
In the alternative method of weaving, as illustrated by Fig. 2 the Jacquard
machine is raised and the first cumber board c remains down at the 3rd pick and
the Jacquard machine is raised and the 2nd cumber board d remains down at the
6.h pick while an extra pick of ground weft is put into the same shed as a figure
pick or the Jacquard machine might be raised and the respective cumber board
remain down at the 2nd and 7th picks.

only require a drop box at one side of the loom and consequently the cost of
production is lessened.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
The herein described improvements which consist chiefly in weaving a certain
specified figured fabric with two ground picks of weft in place of one ground pick
as set forth in Patent numbered 17088 of 1892 whereby drop boxes are required at
one side only of the loom.
