Improvements in Apparatus for Immersing, Moving, and Squeezing
Hanks of Yarn, Tape, or the like.
We, WILLIAM MATHER, and DAVID PICKEN SMITH, of Salford Iron Works,
Manchester, in the County of Lancaster, Engineers, do hereby declare the nature
of this invention to be as follows :-
In treating hanks of yarn, tape or the like for bleaching, dyeing and other
purposes it is necessary to immerse and move them in various liquors, and when
they are withdrawn from one liquor they should have it squeezed out as completely
as possible, otherwise its presence vitiates the succeeding liquor with which the
hanks are treated. This invention relates to apparatus by which hanks are
automatically immersed in tanks containing liquors for treating them, are moved
therein and are subjected to a squeezing action, the apparatus being so arranged
For
as to give facility for removing or replacing any of the hanks operated on.
this purpose, we arrange the hanks in pairs each pair being carried on an arm
which can move in a vertical plane being pivotted to a link of a chain that travels
horizontally along the adjacent edges of two parallel tanks. On each side of each
arm is mounted a pair of rollers on which the one of the hanks is held, the rollers
next the pivot being mounted on a sliding sleeve pressed by a spring towards
another pair of rollers mounted on the chain link to which the arm is pivotted.
These latter rollers, which operate as squeezing rollers, are caused to revolve, as
the chain carrying them travels, by a pair of revolving cylinders under which they
pass, and by their revolution, they cause the hanks to travel round the pairs of
rollers which carry them squeezing the hanks between them and the adjacent pair
of these rollers. On each of the arms is a tail, preferably furnished with an
antifriction roller, which travels along a bar made with suitable cam inclines so
that, as each arm approaches an end of either tank or a partition dividing the
tank, it is raised sufficiently high to pass over the end or partition, and after so
passing, it descends again to immerse the hanks which it carries.
The one of the rollers which carry each hank being mounted on a sliding sleeve,
can at any time be drawn by hand back from the squeezing roller so that a hank
can be taken out from between it and the squeezing roller or can be introduced
between them. The drawing back may also be effected automatically at any part
of the travel of the arm by means of a cam incline acting on a tail piece projecting
from the sliding sleeve, this tail piece being preferably furnished with an anti-
friction roller.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Immersing, Moving, and Squeezing
Hanks of Yarn, Tape, or the like.
We, WILLIAM MATHIER and DAVID PICKEN SMITH, of Salford Iron Works,
Manchester in the County of Lancaster, 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:—
In treating hanks of yarn, tape or the like for bleaching, dyeing and other

page_text: purposes, it is necessary to immerse and move them in various liquors, and, when
they are withdrawn from one liquor, they should have it squeezed out as com
pletely as possible, otherwise its presence vitiates the succeeding liquor with which
the hanks are treated. This invention relates to apparatus by which hanks are
automatically immersed in tanks containing liquors for treating them, are moved
therein and are subjected to a squeezing action, the apparatus being so arranged as
to give facility for removing or replacing any of the hanks operated on.
For this
purpose, we employ apparatus as we shall describe referring to the accompanying
drawings.
Fig. 1 is a half plan on the right and a half plan at a lower lever on the left.
Fig. 2 is a transverse section on X X of Fig. 1 shewing one pair of hanks
immersed and another pair being raised.
We arrange the hanks H in pairs each pair being carried on an arm A which
can move in a vertical plane being pivotted at a to a frame projecting from a link
of a chain C which is driven by a chain wheel L and travels horizontally along
the adjacent edges of two parallel tanks T. On each side of each arm A is
mounted a pair of rollers A' A' on which the one of the hanks is held, the rollers
next the pivot being mounted on a sliding sleeve A³ pressed towards another pair
of rollers A' mounted on the chain link to the projection from which the arm A is
pivotted.
It is of advantage to provide each chain link carrying the arm A with a roller
running on a rail r.
To the sliding sleeve A is attached a rod a¹ having on its end a vertical roller a
which travels behind a bar a³ fixed at each end on arms projecting down from a
rocking shaft a¹.
At one end of the apparatus each of the two rocking shafts a
has an arm a to which is attached a chain passing over pullies a and carrying
weights a'.
By means of these weights the sliding sleeves A³ are drawn towards the
squeezing rollers A' which are caused to revolve as the chain C travels by a pair
of revolving toothed cylinders D under which they pass, and, by their revolution,
they cause the hanks H to travel round the pairs of rollers A' A² which carry
them, squeezing the hanks between them and the squeezing rollers A*.
By varying the shape of the bars a³ against which the rollers a² bear, more or
less squeezing of the hanks can be effected at different parts of their travel.
On each of the arms A is a tail A (which may be furnished with an antifriction
roller) which, as each arm A approaches an end of either tank, causes it to be
raised sufficiently high to pass over the end of the tank, and after so passing, allows
it to descend again to immerse the hanks, which the arm carries. For this purpose,
near the end of the tank is fixed an inclined guide t which, as the arm A reaches
it, causes the arm to take an inclined position. The tail A of the arm A is thus
brought within range a flanged wheel E, part of the flange of which is cut away
to an inclined shape. The shoulder of the flange where the cut away portion
begins, as it revolves, catches the tail A' and thus cants the arm A upwards, and
the tail A being then pushed under a disc F', is held in that position while the arm
is carried round the end of the tanks.
When the tail A' is carried half round under the wheel F which revolves along
with the chain C, the tail meets a second wheel E' with a flange cut similarly to
that of E but to the opposite hand, and by the revolution of this flanged wheel
the arm A. is allowed to descend into the tank. When the tanks are divided into
two or more compartments by partitions, a similar arrangement of flanged
wheels E E' is provided for the purpose of raising and lowering the arms A as
they pass the partitions.
The one A of the rollers which carry each hank being mounted on a sliding
sleeve A³ can at any time be drawn by hand back from the squeezing roller A¹ so
that a hank H can be taken out from between it and the squeezing roller or can
be introduced between them. The drawing back is effected automatically at one
end of the apparatus for the purpose of putting on and taking off hanks, the

page_text: rollers a being for this purpose arranged to travel round a circular flange K
revolving along with the wheel F and the chain wheels L.
The mechanism for giving motion to the various parts of the apparatus may be
varied; as shewn in the drawings it is as follows:-Fast and loose pullies P are on
a prime moving shaft P, a spur pinion P2 on which drives a spur wheel P³ gearing
with another spur wheel P; from P3 and P* are driven the toothed cylinders D.
A sprocket wheel on the axis of P4 by means of a chain C₁ drives the shaft E
on which the flanged wheel E is loosely fitted. A sprocket wheel on the axis of P³
by means of a chain C2 drives the shaft E on which is fixed the flanged wheel E'.
A sprocket wheel on the shaft E' by means of a chain C³ drives the flanged
wheel E.
In a similar manner at the feeding end of the apparatus the shaft E³ drives a
flanged wheel directly and, by means of sprocket wheels and a chain similar to C³,
drives another flanged wheel as E is driven. The chain wheel L is driven in the
following manner. A bevil wheel M on the prime motor shaft P₁ drives a bevil
pinion on a vertical shaft M' which by means of a pair of bevil wheels below
drives a horizontal shaft M². On this shaft there is a worm M* which gears with
a worm wheel M³ on the shaft of the chain wheel L.
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. Apparatus for immersing, moving and squeezing hanks, wherein arms carrying
pairs of rollers holding hanks and pairs of squeezing rollers are caused by a chain
to travel along a tank and return along another, subject to mechanism which at.
each end of the tanks causes the arms to rise and descend, substantially as
described.
2. In apparatus such as is above referred to, mounting one of each pair of the
rollers carrying the hanks on a sleeve sliding on the arm and providing this sleeve
with a rod and roller travelling along a weighted bar, whereby the hank roller is
drawn more or less forcibly against the squeezing roller, substantially as and for
the purpose set forth.
