WILLIAM LAPWORTH of Hopedale in the State of Massachusetts in the United
States of America but at present of 55 Chancery Lane in the County of Middlesex,
Engineer do hereby declare the nature of this invention to be as follows:
-
This invention has for its object the production of an elastic fabric having a twilled
face and back, the material showing at the back and face being the weft instead of the
warp which have so appeared in all elastic fabrics having a twilled face and back.
By causing the weft to constitute the visible part of the face and back of the fabric
it is possible to use cheaper threads for the warp as the weft completely conceals it.
Preferably the weft or filling will be introduced by one shuttle, but should two
shuttles be employed with weft threads of different colours the back and face of the
fabric would be of different colours, the colour depending upon the colour of
the weft.
The fabric herein described is woven in what is called a six time motion, the warp
threads being up three and down three, the fibrous warps being carried by the heddles
of three harness frames, and the rubber or cord warp by the heddles of one harness
frame.
'
For the sake of simplicity of explanation I will proceed to describe a series of
motions such as would be gone through in carrying out my invention designating the
threads employed respectively as follows:-
The warp threads A are contained in the heddles of one harness-frame, those B in
the heddles of a second harness-frame, those C in the heddles of a third harness-frame,
and the rubber or cord warps R by the heddles of a fourth harness-frame.
The threads are drawn through the space between the dents of the usual reed, so
hat there will be a rubber warp R in every dent, but the threads A B and C, will he
u separate dents, thus making a fibrous and a rubber warp in each dent.
As an illustration: In the first shed or pick of the six time motion, the warp
hread A will be up, but it goes down at the second pick and remains down for the
hird and fourth picks and rises for the fifth and sixth picks, thus making that warp
tand up for three and down for three.

page_text: In the first pick, the thread B is up, and it remains up for the second and thira
picks, and it is down for the fourth, fifth and sixth picks.
The thread C during the first pick is down, and it remains down at the second pick,
and rises and remains up for the third, fourth, and fifth picks going down on the
sixth pick.
The rubber threads R held up for one pick are lowered for the next pick, and
vice-versa.
Separating the warps as described for the insertion of the weft enables the latter to
appear upon both the face and back of the fabric as a full twill covering the warp.
By these means as aforesaid I produce a fabric, composed of fibrous and rubber or
cord warps, and a filling, the fibrous warps thrown alternately to the face and back of
the fibre for three picks, the rubber or cord warps being retained at the centre of the
fabric and being substantially concealed by the weft which crosses the rubber warp at
opposite sides at alternate picks whereby the filling is thrown up prominently to form
a twilled face and back for the fabric.

I WILLIAM LAPWORTH of Hopedale in the State of Massachusetts in the United
States of America but at present of 55 Chancery Lane in the County of Middlesex,
Engineer 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 has for its object the production of an elastic fabric having a twilled
face and back, the material showing at the back and face being the weft instead of
the warp which has so appeared in all elastic fabrics having a twilled face and back.
By causing the weft to constitute the visible part of the face and back of the fabric it
is possible to use cheaper threads for the warp, as the weft completely conceals it.
Preferably the weft or filling will be introduced by one shuttle; but should two
shuttles be employed with weft threads of different colours, the back and face of the
fabric would be of different colours, the colour depending upon the colour of
the weft.
The fabric herein described is woven in what is called a "six-time motion," the
warp threads being up three and down three, the fibrous warps being carried by the
heddles of three harness-frames, and the rubber or cord warp by the heddles of one
harness-frame.
Figure 1 is a plan view of a portion of a fabric embodying my invention, the warp
and weft threads being separated to exhibit their crossings.
Figure 2 is a cross-section of the fabric in the line or shed containing the first pick
of the pattern. Figures 3 to 7 show like views of the different picks, completing the
pattern; and Figure 8 shows the first pick of the repeat of the pattern, it being the
same as that shown in Figure 2. In Figure 1 the warps are supposed to be contained
in six spaces of the reed."
The warp-threads a are contained in the heddles of one harness-frame, those 6 in
the heddles of a second harness-frame, those c in the heddles of a third harness-frame,
and the rubber or cord warps r by the heddles of a fourth harness-frame.
The threads are drawn through the space between the dents of the usual reed, so
that there will be a rubber warp, r, in every dent; but the threads a, b, and c will be
in separate dents, thus making a fibrous and a rubber warp in each dent.
In the first shed or pick of the six-time motion (represented in Figure 2) the warp-
thread a is up; but it goes down at the second pick, and remains down for the third
and fourth picks, and rises for the fifth and sixth picks, thus making that warp stand
up for three and down for three.
In the first pick (see Figure 2) the thread b is up, and it remains up for the second
and third picks, and it is down for the fourth, fifth, and sixth picks.
The thread c in Figure 2 (showing the first pick) is down, and it remains down at
-

page_text: the second pick, and rises and remains up for the third, fourth, and fifth picks, going
down on the sixth pick.
The rubber threads », held up for one pick, are lowered for the next pick and
vice-versa.
Separating the warps, as described, for the insertion of the weft enables the latter
to appear upon both the face and back of. the fabric as a full twill covering the warp.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I am aware of Stokes and
Hudson's patent No. 87785 and declare that I do not claim anything described and
claimed therein but what I claim is :-
:-
The herein-described fabric, composed of fibrous and rubber or cord warps and a
weft, the fibrous warps thrown alternately to the face and back of the fabric for three
picks, the rubber or cord warps being retained at the centre of the fabric, and being
substantially concealed by the weft, which crosses the rubber warp at opposite sides at
alternate picks, whereby the weft is thrown up prominently to form a twilled face and
back for the fabric, all substantially as described.
