Improvements in Wringing Machinery to be Used in Connection
with the Starching, Dressing, Sizing, Liquoring. Soaping, or.
Washing of Woven Fabrics.
We, DUNCAN STEWART, and ROBERT WALKER, of London Road Iron Works,
Glasgow, in the County of Lanark, North Britain, Engineers, do hereby declare
the nature of this Invention to be as follows, that
to say:
Our said Invention has for its object to apply a wringing process with a twisting
action in a continuous manner to woven fabrics, in connection with the starching,
dressing, sizing, liquoring, soaping, or washing of such fabrics, the process being
effected by means of improved machinery, and being such as whilst expressing
superfluous liquid to equalise and thoroughly work into the fabric the starchy or
other liquid used.
In carrying out our Invention we pass the fabric in a gathered or rope-like
condition through a vat containing the starchy or other liquid, or round rollers
supplied therewith; and then we lead the fabric between or through a first pair
of nipping rollers held in a stationary framing. The fabric next passes through a
second pair of nipping rollers held in a hollow frame or tube which is made to
rotate about an axis coincident with the line along which the fabric passes; and
afterwards it passes through a third pair of nipping rollers which are held in a
stationary framing. The second or revolving pair of rollers twist and thereby wring
the fabric between the first and third pairs which are stationary. The tendency is
to put a right-hand twist into the part of the fabric between the first and second
pairs of rollers and a left-hand twist in the part between the second and third pairs
of rollers or vice versa; but as the fabric moves through continuously the twists
put into it between the first and second pairs of rollers is just neutralised between
the second and third pairs. A fourth pair and a fifth pair of rollers may be added,
or if wished a greater number, every even-numbered pair being made a revolving
pair and every odd-numbered pair a stationary pair the series alway terminating

page_text: with an odd-numbered stationary pair. The fabric may be passed through the several
pairs of rollers in immediate succession, or it may be passed through starchy or
other liquid between successive applications of the wringing operation to it. The
fabric is finally, by preference passed through an airing machine of the kind described
in our Patent Specification No. 5113 of 1887.

Improvements in Wringing Machinery to be Used in Connection

Washing of Woven Fabrics.
We, DUNCAN STEWART, and ROBERT WALKER, of London Road Iron Works,
Glasgow, in the County of Lanark, North Britain, Engineers, 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, that is
to say :-
Our said Invention has for its object to apply a wringing process with a twisting
action in a continuous manner to woven fabrics in connection with the starching,
dressing, sizing, liquoring, soaping, or washing of such fabrics, the process being
effected by means of improved machinery and being such as whilst expressing
superfluous liquid to equalise and thoroughly work into the fabric the starchy or
other liquid used.
In carrying out our Invention we pass the fabric in a gathered or rope-like
condition through a vat containing the starchy or other liquid or round rollers
supplied therewith; and then we lead the fabric between or through a first pair of
nipping rollers held in stationary framing. The fabric next passes through a second
pair of nipping rollers held in a hollow frame or tube which is made to rotate about
an axis coincident with the line along which the fabric passes; and afterwards the
fabric passes through a third pair of nipping rollers which are held in stationary
framing. The second or revolving-twisting pair of rollers twist and thereby wring
the fabric between the first and third pairs which are stationary. The tendency is to
put a right-hand twist into the part of the fabric between, the first and second pairs of
rollers and a left-hand twist in the part between the second and third pairs of rollers,
or vice versa but as the fabric moves through continuously the twists put into it
between the first and second pairs of rollers is just neutralised between the second and

page_text: third pairs. A fourth pair and a fifth pair of rollers or if wished a greater number
may be added, every even-numbered pair being made a revolving-twisting pair and
every odd-numbered pair a stationary pair, the series always terminating with an
odd-numbered stationary pair. The fabric may be passed through the several pairs of
rollers in immediate succession, or it may be passed through starchy or other liquid
between successive applications of the wringing operation to it. The fabric is finally,
by preference, passed through an airing machine of the kind described in our Patent
Specification No. 5113 of 1887.
On an accompanying sheet of explanatory drawings is shown a sectional side
elevation of a simple modification of our improved wringing machinery.
The fabric, 2, which is in a gathered or rope-like condition is passed any suitable
number of times around rollers, 3, rotating in a vat, 4, which contains the starchy or
other liquid to which the fabric is to he subjected. From these rollers, 3, the fabric, 2,
is led between or through a first pair of weighted nipping rollers, 5, 6, held in
bearings in stationary housings, 7, fixed to the main framing, 8, which is secured to
the top of the vat. 4, at one end and to larger stationary housings, 9, at the other enl
the latter being themselves fixed to the top of the vat, 4. The fabric, 2, next passes
through a second pair of nipping rollers, 10, 11, which are held in bearings in a hollow
frame or tube, 12, carried in bearings in transverse frame bars, 13, fixed to the
framing, 8. The tube, 12, is formed with a pulley surface on one end and is made to
rotate by a belt, 14, from a pulley, 15, on a power shaft, 16. The fabric, 2, next
passes alternately through pairs of stationary rollers, 5, 6, and revolving-twisting
rollers, 10, 11, similar to those already described, the series terminating with a
stationary pair, 5, 6, which are larger than the others and receive their motion by a
belt, 17, from a power shaft not shown so as to draw the fabric through the machine.
A reverse motion is, by preference, given to the second pair of revolving-twisting
rollers, 10, 11, by crossing the belt, 14, so as to give opposite twists to the fabric from
those given to it by the preceding pair of rollers, 10, 11.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1 For the continuous twist-wringing of a woven fabric, the combination of three
pairs of nipping rollers through which the fabric is passed, the first and third pairs
of rollers being in stationary bearings and the second pair being in a frame or
tube carried in bearings coaxial with the line of fabric, with means for making the
said frame or tube rotate, and with means for drawing the fabric through the rollers
the parts being arranged and operating substantially as herein before described.
2-For the continuous twist-wringing of a woven fabric, the combination of a series
of pairs of nipping rollers, the odd-numbered pairs being in stationary bearings and
the even-numbered pairs being in frames or tubes rotating coaxially with the line of
fabric, with means for drawing the fabric through the rollers substantially as herein-
before described.
