PROVISIONAL SPECIFICATION.
Improved Apparatus for Dyeing, Soaping. Washing, and
Finishing Yarn.
I GEORGE WOOLLEY LIDDIARD of Thornsett Birch Vale (near Stockport) in the
County of Derby Manager at Bleach Works, do hereby declare the nature of this
invention to be as follows:-
This improved apparatus consists principally of a series of vats or tanks (say five)
arranged in a circular form around a central vertical shaft and separated from each
other by radial divisions. This central shaft is caused to revolve by means of suitable
gearing, and at its upper end, some distance above the top of the tanks it carries a
loose boss to which is attached a frame having (say) ten radial arms extending over
the tanks.
Each of these radial arms is fitted near its outer end with hanging brackets carrying
a pair of pressing rollers, over the lower one of which the hanks of yarn are hung. The
upper rollers are pressed down upon the lower rollers by means of a spring acted upon
by a handwheel and screw. The lower rollers are keyed upon a series of radial shafts
the inner ends of which are fitted with bevil pinions all gearing into a bevil wheel keyed
on the central shaft, by which means the rollers are caused to revolve so as to give a
kind of continuous revolving motion to the hanks of yarn which are placed over the
lower rollers and hang down in to the liquor in the tanks.
The brackets which carry the radial shafts are bolted onto a large spur wheel which
is loose on the central shaft and is driven by a spur pinion and thus the whole radial
frame (with the rollers) has a slow revolving motion given to it which, whilst the
rollers revolve rapidly moves the hanks slowly across each tank and over the divisiou
into the next and so on in succession all round the series.
The frame is supported on friction wheels running on a circular rail upon the inner
edge of the tanks."
There is a gap between the first and last tanks and the attendant stands at that
part and as the frame revolves slowly past him he removes the banks one after-the

page_text: other and substitutes fresh ones so that the operation is continuous and no time is lost
in changing the banks.
Provision is made for drawing off and renewing the contents of the various tanks
when required and for keeping any or all of the same at boiling heat or other required
temperature.
The liquor in the various tanks will depend in a great measure upon the operation
to be performed as an example for soaping and finishing bleached yarn I have clean
water in the first fourth and fifth tanks, soap and water in the second and soap water
and blue in the third.

Finishing Yarn.
I GEORGE WOOLLEY LIDDIARD of Thornsett, Birch Vale near Stockport in the
County of Derby, Manager at Bleach Works do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particulary described
and ascertained in and by the following statement. :-
My invention relates to the construction of a circular apparatus for the above
purposes wherein the operation is practically continuous and ng time is lost in
changing the hanks or in passing them from one cistern or tank into another.
The construction of my improved apparatus will be readily understood on reference
to the annexed two sheets of drawings and the following explanation thereof.
Sheet 1 of the drawings represents a vertical section and Sheet 2 a plan view, partly
in section, of my improved apparatus which consists principally of a series of vats or
tanks a (say five) arranged in a circular form around a central vertical shaft b and
separated from each other by radial divisions c. The central shaft is caused to
revolve by means of a bevil pinion d which is in gear with a bevil wheel e keyed upon
a horizontal driving shaft fand at the upper end of the said shaft b, some distance
above the tanks a it carries a loose boss g to which is cast or attached a frame having
(say) ten radial arms extending over the tanks.
Each of these radial arms his fitted near its outer end with hanging brackets
carrying a pair of pressing rollers k, over the lower one of which () the hanks of
yarn are to be hung.
The upper rollers & are pressed down upon the lower rollers by means of levers
(which may be weighted) or by a spring acted upon by a hand-wheel and screw. The
lower rollers are keyed upon a series of radial shafts m the inner ends of which are
fitted with bevil pinions mx all gearing into a bevil wheel n which is keyed on the
central vertical shaft by which means the rollers k¹, are caused to revolve so as to
give a kind of continuous revolving motion to the hanks of yarn which are placed
over the lower rollers and hang down into the liquor in the tanks a.
To prevent
the hanks of yarn from gradually working their way outwards and so falling off the
outer ends of the rollers I propose to employ a guard o which is hung from the
lever (as shewn on Sheet 1) and is thus moved out of the way when the said lever (and
the upper roller ) is raised for removing and replacing the hanks. The brackets p
which carry the radial shafts m are bolted to a large spur wheel which is loose on
the central shaft and is driven by means of a spur pinion actuated from the
horizontal driving shaft, and thus the whole radial frame & carrying the rollers k, k¹
has a slow revolving motion given to it which (whilst the rollers themselves revolve
rapidly) moves the banks slowly across each tank a and over the divisions c into the
next and so on in succession all round the series.

page_text: The radial frame may be supported on friction wheels carried by the brackets i*
and running on a circular rail upon the inner edge of the tanks a but I prefer to fix a
circular plate s to the frame and allow this to run on the friction rollers t, carried by
the tanks as shown on Sheet 1 of the drawings.
There is a gap (see Sheet 2) between the first and last tanks, and the attendant
stands at that part and, as the radial frame revolves slowly past him, he removes the
hanks one after the other and substitutes fresh ones so that the operation is practically
continuous and no time is lost in changing the hanks.
Provision is made for drawing off and renewing the contents of the various tanks
when required and for keeping any or all of the same at boiling heat or other required
temperature.
The liquor in the various tanks will depend in a great measure upon the operation
to be performed; as an example for soaping and finishing bleached yarn I have clean
water in the first, fourth, and fifth tanks, soap and water in the second, and soap
water and blue in the third.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I claim is :-
The improved apparatus for dyeing, soaping washing and finishing yarn, consisting of
a series of cisterns or tanks arranged in a circle in combination with a radial revolving
frame mounted on a central shaft and carrying revolving rollers constructed and
operating substantially in the manner hereinbefore particularly set forth and illustrated
by the drawings annexed.
