PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Woven Goods such as Dimity
Quilts and the like.
We, JOHN ROBERT BARLOW, of Greenthorne, Edgeworth, near Bolton, in the
County of Lancaster, Manufacturer, and JACOB WARBURTON, of 291. Blackburn
Road, Bolton, aforesaid, Mill Manager, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to improvements in the manufacture of woven goods such
as dimity quilts and the like in which there are a number of warp threads
together governed by a single needle.
The dimity quilt or like fabric is woven with one warp and one weft in two
sets of healds one making the ridges and the other the furrows or depressions
between the ridges the cloth being reversible. The object of our improvements is
to produce figures of either warp or weft on both sides of a dimity quilt or similar
fabric and to effect this we employ a combination of cumber boards with a
jacquard machine and grifes. For example when weaving say a four end twill or
satin cloth, we employ four cumber boards to work the warp and produce the
weft figure on the top surface and we also employ a double lift single cylinder
jacquard machine to work the warp and produce, the warp figure on the top
surface.
Four warp threads one from each cumber board are connected to each needle
of the jacquard machine, the boards being divided two boards to one grife and
two boards to the other grife alternately two picks from each grife. We vary
the number of picks per card according to the fineness of the cloth desired.
Instead of four threads to each needle we might have two or any other greater
number required. When weaving an eight end satin we should require eight
cumber boards and four grifes in the jacquard machine.

page_text: 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 woven goods such
as dimity quilts and the like in which there are a number of warp threads
together governed by a single needle.
The dimity quilt or like fabric is woven with one warp and one weft in two
sets of healds one making the ridges and the other the furrows or depressions
between the ridges the cloth being reversible. The object of our improvements is
to produce figures of either warp or weft on both sides of a dimity quilt or similar
fabric and to effect this we employ a combination of cumber boards with a
jacquard machine and grifes. For example when weaving say a four end twill or
satin cloth, we employ four,cumber boards to work the warp and produce the
weft figure on the top surface and we also employ a suitable jacquard machine to
work the warp and produce the warp figure on the top surface.
Four warp threads one from each cumber board are controlled by each needle
of the jacquard machine, the boards being divided, two boards to one grife and
two boards to the other grife alternately two picks from each grife. We vary
the number of picks per card according to the fineness of the cloth desired.
Instead of four threads to each needle we might have two or any other greater
number required. When weaving an eight end satin we should require eight
cumber boards and four grifes in the jacquard machine.
The accompanying sheet of diagrams shows the method of connecting the
jacquard harness to the cumber boards and the order of shedding when weaving,
Fig. 1 a four end twill, Fig. 2 a four end satin, and Fig. 3 an eight end satin.
The right hand side of each of the diagrams, Figs. 1, 2 and 3 shows the order
of shedding.
Fig. 4 is a diagram of a four end twill in which the pattern is produced by
the tie up illustrated in Fig. 1.
Fig. 5 is a similar diagram of an eight end satin in which the pattern is
produced by the tie up illustrated in Fig. 3.
Referring first to Figs. 1 and 2, a designates the first grife and 6 the second
grife and 1, 2, 3, 4, the four cumber boards. The first grife a is connected to
the cumber boards 1 and 4 by the cords 1" and 4ª respectively, and the second
grife to the remaining cumber boards 2 and 3 by the cords 2 and 3b
respectively.
Fig. 4 represents a pattern of a four end twill woven all across the piece by
the cumber boards 1, 2, 3, 4, the figure being a weft figure while the central
square of the pattern has, in addition to the same figure, a reverse diagonal of
warp produced by the jacquard machine acting through the grifes a and b on
their connected cumber boards.
When weaving an eight end satin cloth, Fig. 3, the eight cumber boards are
numbered one to eight and the four grifes are lettered a, b, c, d.
The first grife a is connected by cords 1" S to cumber boards 1 and 8.
The second grife is connected by cords 2b 7 to cumber boards 2 and 7.
The third grife c is connected by cords 3° 6° to cumber boards 3 and 6.
The fourth grife d is connected by cords 4d 5d to cumber boards 4 and 5.
Fig. 5 represents a pattern of an eight end satin woven all across the piece by
the cumber boards 1, 2, 3, 4, 5, 6, 7, 8, the figure being a weft figure while the
central square of the figure has the same pattern with the addition of the reverse
warp figure produced by the jacquard machine acting through the four
grifes a, b, c, d, on their connected eight cumber boards.
What is new in the combination is the manner of connecting the grifes to the
cumber boards as shown in the diagrams and having each needle governing a
number of warp threads so as to change at will the weft twill or satin from one
side of the cloth to the other by the action of the jacquard and thereby produce
a figure on either side of the cloth as required,

page_text: 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 combinations of cumber boards with the grifes of a
jacquard machine for the purpose of throwing the weft twill or weft satin to
either face of the cloth as desired when weaving a dimity quilt or similar rever-
sible figured twill or satin cloth in which two or more warp threads together are
governed by the same needle of the jacquard machine.
