PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Mercerising Woven Fabrics.
I, JOHN HENRY WOOD, of Moston Dye Works, Newton Heath, near Man-
chester, in the County of Lancaster, Dyer and Finisher, do hereby declare the
nature of this invention to be as follows:-
-
This invention relates to apparatus to be employed in mercerising woven
fabrics, the object being to construct a machine in which the complete process
may be carried on whilst the fabric is stretched.
For this purpose I provide two tanks of suitable length depth and width
placed end to end, with suitable squeezing rollers between the outlet end of one
(which contains the mercerising liquor) and the inlet end of the other, in which
the fabric is to be washed.
At the upper part of each tank I fit a pair of endless travelling chains having
pins or clips (like those used in stentering machines) mounted on pulleys which
are adjustable to suit variation in the widths of different cloths. These chains
may be parallel or slightly diverging from each other as desired.
The levels of the liquor and of the washing water in their respective tanks
are above the level of the lower parts of these chains, which are of such a length
and moved by suitable mechanism or gearing in such a direction that the fabric,
fed by a suitable guide or tension roller or rollers is drawn down by the pins or
clips on the chains in the first tank and carried through the mercerising liquor
from the front of the rear end of the said tank, and is then passed between the
squeezing rollers above described and drawn down again by the pins or clips on
the chains in the second or washing tank and carried through the water to the
other end thereof, where it is then passed through a second pair of squeezing
rollers and may then be plaited down or otherwise disposed of.
Thus the immersion of the fabric in the liquor and washing baths is carried
on while the said fabric is stretched.

page_text: 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 relates to apparatus to be employed in mercerising woven
fabrics the object being to construct a machine in which the complete process
may be carried on whilst the fabric is stretched.
In the accompanying drawing Fig. 1 is a side view, and Fig. 2 a plan illus-
trating our improved apparatus. Similar letters refer to similar parts in both
views.
For the purpose of my invention I provide two tanks as a a¹ of any preferred
length, depth and width placed end to end with squeezing rollers as fitted
over the outlet end of the tank a which contains the mercerising liquor and the
inlet end of the tank a¹ in which the fabric is washed. At the upper part of
each tank I fit a pair of endless travelling chains as c c and d d, said chains
having pins or clips similar to those used in stentering machines and mounted
on pulleys ee which are adjustable on the shafts f f to suit variation in the
widths of different cloths. These chains may be parallel or slightly diverging
from each other as desired. The levels of the liquor and of the washing water
in their respective tanks are above the level of the lower part of the aforesaid
chains which are of such a length and moved by gearing as g in such a direc-
tion that the fabric which is fed by suitable tension roller or rollers is drawn
down by the pins or clips on the chains c c in the first tank a and carried
through the mercerising liquor from end to end of said tank passing from thence
up between the squeezing rollers 6 61 and is drawn down again by the pins or
clips on the chains d d in the second or washing tank a' and carried through the
water to the opposite end of said tank when it is passed through a second pair
of squeezing rollers as q q¹ and may then be plaited down or otherwise disposed
of. Jets of water as may be sprayed on to the fabric before passing through
the last named rollers. By these means the immersion of the fabric in the liquor
and washing baths is carried on while the fabric is being stretched.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
In apparatus employed for mercerising woven fabrics the combination of a
tank for containing mercerising solution placed end to end with a tank con-
taining water, endless chains with hooks or clips thereon passing over pulleys
placed in pairs at or near each end of each tank with the lower part of said
pulleys below the surface of the liquid that is in the tanks, squeezing rollers
placed over the outlets of said tanks, and suitable gearing for imparting motion
to the aforesaid pulleys chains and rollers, all substantially as and for the
purpose herein before described.
