PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Boiling, Scouring, or Cleansing
Textile Fabrics.
I, WILLIAM HUTCHINSON, of Weaste, Salford, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
In a tank or vat which contains the scouring liquor, is journalled a roller over
which the cloth is caused to pass. This roller is preferably divided into a series of
sections all rotated by the same shaft. Placed above this roller are a number of
rolls or pulleys one for each section or specified length of the first roller. This
second set of rolls has a rolling contact with the first and each can rotate inde-
pendently of the other. In addition to the rolls there are two, three or more,
preferably three, sets of guide pulleys one set placed immediately below the rollers
and two sets at or near the bottom of the tank or vat. The top rolls are each
weighted separately so that one may rise or fall without interfering with any of the
others. The weights rest on the ends of the spindles and extend to the sides of the
tank to act as guides or they may depend from the spindles.
The main roller is driven by means of a friction gear or other suitable device
from a small engine or shafting and the tank is heated by steam entering in by a
perforated pipe at the bottom.
When in operation the liquor in the tank is heated to boiling by the steam and
the cloth is passed and re-passed into the boiling liquor. The cloth traverses under
one of the bottom guide pulleys into the boiling liquor over the top guide pulleys
and again under a bottom guide pulley into the liquor over the main roller and
under one of the weighted rollers by which all the liquor is squeezed out of it.
This operation is repeated some 12 or 14 times as the cloth passes through the
machine, from 15 to 30 minutes being occupied in traversing from one side of the
machine to the other.
Instead of the top guide pulleys a second set of weighted rolls may be employed.
The guide pulleys are set at the proper angle to direct the cloth from one roller or
pulley to the next.

Improvements in Apparatus for Boiling, Scouring, or Cleansing
Textile Fabrics.
I, WILLIAM HUTCHINSON of Weaste, Salford, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention and in what manner the
same to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention relates to apparatus in which in the process of bleaching textile
fabrics are treated with a boiling alkaline or other liquor for the purpose of
scouring or cleansing them and is designed with the object of providing apparatus
in which the cloth will while being boiled be repeatedly removed from the liquor
and have the liquid with which it is saturated removed from it before it re-enters
the main body of the liquor.
It will be fully described with reference to the annexed drawings.
Fig. 1, being elevation partly in longitudinal section.

I provide a tank or vat A of any suitable size or construction to contain the
Scouring liquor which is heated or boiled by means of a perforated steam pipe B
placed at the bottom.
In this tank A I place five sets of rollers or pulleys over or in contact with
which the cloth is caused to pass in its passage in and out of the liquor through
the machine. The set of rollers or pulleys C are placed on a single shaft D
running from end to end of the machine to which they are keyed or otherwise
attached. The shaft D is driven by a pulley or other suitable means and from it
the several parts of the apparatus receive motion. Instead of being made in several
separate sections or pulleys a single roller may be substituted for the pulleys C but
I prefer to use them as separate pulleys.
The second set of pulleys E are placed above the pulleys C and in rolling contact
with them each being journalled separately so as to rotate independently one of the
other. The pulleys E are each kept in position by sliding guide weights F which
rest on the spindles G of the pulleys and slide up and down between guides f
attached to the sides of the tank. Each of the pulleys E are thus weighted with a
separate weight at each side and each one can rise or fall without interfering with
either of the others so that any extra thickness passing between any pair of the
pulleys C and E does not affect the position of the adjacent ones.
The cloth passes alternately between each pair of the first and second set of
pulleys the weighted upper set of pulleys E squeezing the liquor from the cloth as
it passes over the adjacent pulley C.
The remaining three sets of pulleys H, I, and J act as guide pulleys to guide or
direct the cloth backwards and forwards from the liquor to the squeezing pulleys
and back again to the liquor so that the cloth is repeatedly taken from the liquor,
the liquor squeezed out and then again returned thereto. The pulleys H and I are
each pair set in a skeleton frame K near the bottom of the tank A. and immersed
in the scouring liquor. The frames K are each set on a skew to guide the cloth
forward in a continuous length in spiral form through the machine.
The pulleys J are also journalled in skew frames L supported by the sides of the
tank A by the use of the pulleys J the cloth is raised out of and immersed in the
liquor while passing from the pulley H to the pulley I without being subjected to
squeezing although the action displaces a good deal of the liquor with which the
cloth is saturated.
If desired the pulleys J may be dispensed with where it is required to keep the
cloth a longer time immersed in the scouring liquor or they may be held up against
the under side of the central rollers C so that the liquor may be squeezed from
the cloth.
The shaft to which the pulleys or rollers C are attached projects through the
, ends of the tank, suitable stuffing boxes being provided to prevent the vapour or
steam escaping. This shaft is driven by means of a pulley or friction gear or other
suitable device from a small engine or shafting and the tank is heated by steam
entering in by a perforated pipe B at the bottom.
The tank A is preferably covered in at the top by a wooden cover N provided
along its centre with a trough O into which water for swilling or washing out the
vat flows and is allowed to enter through the plug holes o which are closed when
required by the plugs o¹.
The cloth enters the tank through the aperture P at one end of the cover and
after passing through leaves it through the hole R at the other end when it is
conveyed away over suitable rollers.
When in operation the liquor is filled into the tank until the bottom pulleys are
covered to the depth of about 6 to 8 inches and it is kept heated up to boiling point
by the steam entering through the perforated pipe at the bottom. The cloth entering
by the aperture P is passed over a supplementary pulley p and thence under one of

page_text: the bottom guide pulleys from this it passes up out of the liquor and between the
rollers or pulleys C and E where the liquor is squeezed out of it. From between
the rollers C and E the cloth returns to the liquor passing round the pulley I and
from it up over the pulley J and down again into the liquor round the pulley H
and so on, the cloth being thus passed and repassed into and out of the boiling
liquor. This operation is repeated some 12 or 14 times as the cloth passes through
the machine, from 3 to 5 minutes being occupied in traversing from one side of the
machine to the other. Suitable pipes for conveying the liquor to and from the
tank are used and a gauge for indicating the height of the liquor in the tank may
be fixed near the bottom thereof.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. An apparatus for boiling scouring or cleansing textile fabrics having in a vat
or tank a central roller or pulleys working in conjunction with weighted pulleys
between which the cloth passes and a number of skew guide rollers or pulleys which
guide the cloth backwards and forwards between the squeezing rollers substantially
as described.
2. In an apparatus for boiling scouring or cleansing fabrics the combination with
a central roller of a number of pulleys resting thereon weighted by flat sliding
weights which rest on their axles and in which they are journalled substantially as
described and shewn.
3. An apparatus for boiling scouring or cleansing textile fabrics constructed and
arranged so that the cloth will be passed and repassed into the boiling liquor and
the liquor squeezed from it substantially as described and shewn.
