PROVISIONAL SPECIFICATION.
Improvements in or relating to the Manufacture of Elastic Woven
Fabrics.
We, THOMAS JONES and JAMES JONES trading as T. & J. Jones of Brougham
Street Mills, Leicester, Elastic Web Manufacturers do hereby declare the nature of
this invention to be as follows:-
This invention has reference to the manufacture of elastic woven fabrics and has
for its object certain improvements relating thereto by means of which an elastic
woven fabric having a ribbed surface on each side i.e. back and front may be
produced.
To manufacture a fabric such as mentioned we may employ a weaving loom of
the type, for instance, used in the production of elastic gussetting or webbing and
in addition to the usual series of non-elastic warp threads we may combine a series of
elastic indiarubber warps or threads.
The elastic warps may be under the control of an auxiliary cam or cams and
intermediate levers or mechanism by which their position may be varied from time
to time relatively to the other series of warps, so as to effect an alteration or
variation in the shed for the shuttle and weft thread or threads to pass through and
introduce the thread by which the rib effect on both sides of the fabric is produced.
The said elastic warps are moved up and down in such a manner that the shoot
passes alternately under and over it.
The ribbed elastic fabrics made in accordance with this invention may be used for
belts, braces, bands and other purposes.

Improvements in or relating to the Manufacture of Elastic Woven
Fabrics.
We, THOMAS JONES and JAMES JONES trading as T. & J. Jones of Brougham Street.
Leicester, Elastic Web 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 has reference to the manufacture of elastic woven fabrics and has
for its object certain improvements relating thereto by means of which an elastic
woven fabric having a ribbed surface on each side i.e. back and front may be
produced.

page_text: By preference these elastic ribbed fabrics are woven of narrow widths which
render them suitable in the manufacture of belts, braces, bands and other narrow
width goods.
In carrying out the invention we may employ a weaving loom of the type used
in the production of elastic gussetting or boot web and often referred to as a "terry
loom" and in addition to the usual series of non-elastic warp threads we use a series
of elastic or india-rubber warps.
In producing a narrow ribbed surface web such as described and of what may be
termed an eight shoot pattern, we employ 5 harness shafts, four of which are
provided with non-elastic warps and the other one with elastic or india-rubber warps.
We also employ four edge wire or selvedge shafts.
The shuttle carries the thread by which the rib effect is produced, this shuttle
thread may consist of a single thread of thick or coarse gauge or of a number of
finer gauge threads.
.
In the operation of producing a narrow ribbed fabric such as described the
elastic warp shaft is changed at each pick; the four non-elastic warp shafts at
every fourth pick and the selvedge or edge warps at every pick.
The shaft having the elastic warps is located in the centre of the four non-
elastic warps and the operation is as follows:-
Assuming the elastic warp shaft to have been raised, the shuttle then passes
under it; the said shaft is then lowered and the shuttle passes over it. This is
continued four times in succession, the shuttle being picked at each change of the
elastic warp shaft, and at each fourth pick the four non-elastic warp shafts also
change, two alternate shafts rising and two alternate shafts falling simultaneously,
these operations being repeated ad libitum.
The selvedge warp shafts are also changed every pick as well as the elastic warp
shaft.
Of the four selvedge shafts two rise and two fall simultaneously at each pick,
the alternate shafts moving in the same direction.
The means employed to actuate the shafts and the shuttle is the ordinary
mechanism of the loom and will be at once understood without further description."
It is obvious that fewer or more harness shafts may be employed and the order of
their movements varied somewhat without departing from the main lines of the
invention.
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 :-
1. A woven fabric with a ribbed surface back and front and having a series of
elastic warp threads combined therein substantially as described.
2. The improved woven elastic ribbed fabric substantially as and for the purpose
described.
