Improvements in Machines for Dyeing, Finishing, Sizing, Washing,
and similarly Treating Yarp,
We, FRANCIS DAVIES, of 37, Railway Road, Blackburn, Consulting Engineer,
and ADOLF LIEHMANN, Ph.D., of 10, Marsden Street, Manchester, Consulting
Chemist, both in the County of Lancaster, do hereby declare the nature of this
invention to be as follows:-
This invention relates to that type of machine for dyeing finishing sizing
washing and otherwise similarly treating yarn which is described in the Specifica-
tion of Letters l'atent granted to us No. 21492 dated the 29th September A.D. 1896,
and the object of the present improvements is to render the machine more effective
in use.
For this purpose we employ in combination with the machine, one or more
auxiliary or supply tanks below the level of the working tanks, and one or more
pumps. The working tanks are connected with the supply tanks by valve con-
trolled inlet and outlet pipes respectively. At the commencement of operations,
the pump is started and liquid is thereby transferred from the supply tank to the
working tank or tanks. Should the liquid in the latter tank or tanks rise above
the working level, the excess may be arranged to overflow into the outlet pipe
through which it returns to the supply tank. When the operation has been
completed, the valve controlling the outlet pipe is opened and the whole of the
liquid flows out, so that the tank is then ready for the next operation which may
consist in treating the same yarn with another liquid derived from a second
supply tank, or in treating another batch of yarn with the same or another liquid.
We have found that it is advantageous to squeeze the yarn under treatment.
For this purpose we arrange, parallel with each of the top rollers, or with each
of the bottom rollers, or with each roller, an adjustable plain, fluted or roughened
roller acting as a squeezing roller, so constructed and arranged parallel with the
contiguous working roller that the pressure exerted thereby on the working roller
may be regulated at will, and so also, if desired, that the squeezing rollers may
be removed altogether from the immediate neighbourhood of the working rollers,
individually or collectively.
We have further found that for some processes it is desirable that the working
rollers should be heated and that in other processes they should be cooled. We
arrange for this by making the working rollers, or some of them, hollow, and
connecting them by valve controlled pipes, with a steam supply and with a cold
fluid supply respectively, or with one such supply only. The squeezing rollers
or some of them may also be similarly arranged to be heated or cooled if desired.
Also, it has been found that in some cases it is desirable to provide for the
circulation of gaseous or liquid fluids through the yarn on the working rollers.
For this purpose, the hollow rollers are constructed with perforated peripheries and
the interior of each is connected with an air or force pump or equivalent device
for drawing or forcing the fluids through the yarn on the rollers. "The squeezing

Improvements in Machines for Dyeing, Finishing, Sizing, Washing,
and similarly Treating Yarn,
We, FRANCIS DAVIES, of 37, Railway Road, Blackburn, Consulting Engineer,
and ADOLF LIERMANN, Ph.D., of 10, Marsden Street, Manchester, Consulting
Chemist, both in the County of Lancaster, 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 relates to that type of machine for dyeing finishing sizing
washing and otherwise similarly treating yarn which is described in the Specifica-
tion of Letters Patent granted to us No. 21492 dated the 29th September A.D. 1896,
and the object of the present improvements is to render the machine more effective
in use.
For this purpose we employ in combination with the machine, one or more
auxiliary or supply tanks below the level of the working tanks, and one or more
pumps. The working tanks are connected with the supply tanks by valve con-
trolled inlet and outlet pipes respectively. At the commencement of operations,
the pump is started and liquid is thereby transferred from the supply tank to the
working tank or tanks. Should the liquid in the latter tank or tanks rise above
the working level, the excess may be arranged to overflow into the outlet pipe
through which it returns to the supply tank. When the operation has been
completed, the valve controlling the outlet pipe is opened and the whole of the

We have found that it is advantageous to squeeze the yarn under treatment.
For this purpose we arrange, parallel with each of the top rollers, or with each
of the bottom rollers, or with each roller, an adjustable plain, fluted or roughened
roller acting as a squeezing roller, so constructed and arranged parallel with the
contiguous working roller that the pressure exerted thereby on the working roller
may be regulated at will, and so also, if desired, that the squeezing rollers may
be removed altogether from the immediate neighbourhood of the working rollers,

We have further found that for some processes it is desirable that the working
rollers should be heated and that in other processes they should be cooled. We
arrange for this by making the working rollers, or some of them, hollow, and

In order that our improvements may be more clearly understood we have
appended hereto three sheets of drawings to which we will make reference
hereinafter.
Figure 1 illustrates in sectional elevation part of a machine with our improve-
ments applied.
Figure 2 represents a plan of the same parts.
Figure 3 shows a vertical section of part of the upper portion of the machine
and illustrates one method of applying the pressing rollers.
Figure 4 is a sectional view to a larger scale of one end of one of the pressing
rollers.
Figure 5 is a plan of the machine.
Figure 6 is a horizontal section of some of the lower rollers showing the means
by which fluids or liquids may be admitted to the rollers.
As described in the specification of our patent previously referred to, the machine
consists of sets of upper and lower rollers upon which the hanks of yarn are placed
and which are capable of movement relatively to each other in such a manner that
the yarn may be stretched. The lower set of rollers revolves in a tank containing
the liquid with which the yarn is to be treated. In the drawings hereto attached
the lower rollers are indicated by the letter A, the upper rollers by the letter B,
and the working tank in which the lower rollers revolve by the letter C.
According to the present improvements supply or auxiliary tanks D. are
combined with the working tanks C. We will describe the arrangement of one
supply tank with two working tanks, although of course they may be combined
in any other desired numbers or proportions. The supply tank D is at a lower
level than the working tanks O and is connected thereto by suitable valve con-
trolled inlet and outlet pipes. E is a pump or other elevating or lifting device.
F, F, are the outlet pipes by means of which liquid can be run from the working
tanks to the supply tank, and G is the inlet pipe through which liquid is forced
from the tank D to the tanks C by means of the pump E. The inlet and outlet
pipes are each forked or branched to communicate with both tanks C. H is a
valve in the outlet pipe, having a hollow body through which liquid in the tank C
can overflow into the outlet pipe when it rises above a certain level in the
tank C.
At the commencement of the treatment of yarn in the machine the working
tanks Care filled with the desired liquid. When the operation has been com-
pleted or when desired, the valve controlling the outlet pipe is opened and the
liquid flows back to the supply tank, so that the working fank is ready for the
next operation which may consist in treating another batch of yarn with the
same liquid, or the same yarn with another liquid derived from another supply
tank.
Figures 3, 4, and 5 illustrate the squeezing or pressing rollers and their_con-
struction and application. In the application shown the pressing rollers J are
adapted to engage with the upper working or stretching rollers B, but they may,
if desired, be engaged with the lower rollers or with both the upper and the lower
rollers. The rollers J are mounted in suitable bearings K in movable frames L,
these frames being capable of vertical movement so that the rollers may be
caused to approach or to recede from the upper rollers B. To permit this the
frames are mounted so as to slide upon guide rods M, and are provided with
screw's N which pass through and engage with nuts formed in the interiors of
bevel wheels 0, these bevel wheels O being so mounted in the framing of the
machine as to be capable of rotary motion only. Each bevel wheel gears with
another bevel wheel P secured to a transverse shaft Q which carries a worm
wheel R engaging with a worm upon the shaft S. By the rotation of the shaft
in one direction or the other the pressing rollers J may be moved upon or away
from the rollers B and any desired degree of pressure may be exerted.

The roller illustrated in Figure 4 is provided with an indiarubber sheathing T
but this construction is not essential as the roller may be of plain metal or other
material and may have its surface smooth or corrugated.
In some cases it may be desirable to form either the working or pressing rollers
or both so that they may be heated and cooled. For this purpose they may be
formed hollow asshewn in Figure 6, which represents some of the bottom rollers A.
They are mounted upon hollow shafts which rotate within suitable hollow
casings U to which steam or other fluid or liquid may be admitted. The shafts
are perforated to permit of the desired fluid or liquid entering the rollers, and
the casings U may also act as bearings for the shafts. Although only the bottom
rollers are illustrated as being hollow it is perfectly evident that the upper rollers
or the presser rollers may be similarly formed.
In addition, the hollow rollers may be perforated as indicated at V when it is
desirable to provide for the circulation of fluids or liquids through the yarn upon
the rollers.
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. In a machine of the type described for treating yarn with liquids and the
like, the combination of a working tank in which the lower rollers rotate, a
