TROYIDIONAL SPECIFICATION.
Improvements in and connected with Apparatus for Dyeing, Washing,
and otherwise similarly Treating Yarn in Hanks.
I, THOMAS OWEN ARNFIELD of New Mills near Stockport in the County of
Chester, Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
This Invention relates to that type of apparatus for continuously dyeing, washing.
and otherwise similarly treating yarn in hanks, in which a concentric series of tanks
or vats have rotating above them a concentric series of pairs of rollers upon and
between which the hanks are suspended. By the rotation of the rollers upon their.
axes the hanks are continuously run through the liquor in the vats below, and by the
concentric motion of the rollers the hanks are successively transferred from one vat to
the next through the series. In such machines as they are at present constructed and
arranged, difficulty and inconvenience are experienced in raising and lowering the top
roller for the removal and insertion of the hanks, whilst the hanks are dragged over
the tops of the vats or the divisions separating adjacent vats, and thereby become
twisted and knotted.
These Improvements have for their object to overcome the objections hereinbefore
referred to and for this purpose they consist in the construction and arrangement of
devices for raising and lowering the top roller when it is required for the removal or
insertion of new hanks; and of devices for raising the hanks on their passage from.
vat to vat.
The top roller of each pair is hung from a lever or arm which has mounted upon
one end an antifriction roller, which may be arranged to travel in a circular track..
At a convenient position in this track, a double inclined plane is arranged so that
when the roller arrives at the inclined plane, the motion of the roller up and down the
planes lifts and lowers the top roller.
To a convenient part of the revolving frame there is secured a stud which supports
a lever carrying one or more winches. This lever is guided by a path formed on the
inner edge of the vat or in some other suitable position in such a manner that when
the hanks approach the edges of the vats a ramp or lift in the path raises the lower
end of the arm or lever and the hanks are thereby lifted bodily over the edges of
the vats.

COMPLETE SPECIFICATION.
Improvements in and connected with Apparatus for Dyeing, Washing,
and otherwise similarly Treating Yarn in Hanks.
I, THOMAS OWEN ARNFIELD, of New Mills near Stockport in the County of
Chester, Mechanical Engineer, 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 apparatus for dyeing soaping finishing and
otherwise similarly treating yarn in hanks, in which a concentric series of tanks- or
vats have rotating above them a concentric series of pairs of rollers upon and between
which the hanks are suspended. By the rotation of the rollers upon their axes the
hanks are continuously run through the liquor in the vats below, and by the concentric
motion of the rollers, the hanks are successively transferred from one vat to the next
through the series. In such machines as they are at present constructed and arranged,
[Price 8d7

page_text: difficulty and inconvenience are experienced in raising and lowering the top roller for
the removal and insertion of the hanks, whilst the hanks being dragged over the top
edges of the vats or of the radial divisions separating adjacent vats, thereby become
knotted and twisted.
These Improvements have for their object to overcome the objections hereinbefore
referred to and for this purpose they consist in the construction and arrangement of
devices for automatically raising and lowering the top roller when it is required for
the removal or insertion of new hanks; and of devices for automatically raising the
revolving hanks over the top edges of the vats or of the radial divisions between the
vats and for immersing the banks to the required depth in the liquor and preventing
them from floating therein.
I will describe my Improvements more particularly with reference to the accom-
panying drawings in which Figure 1 is a partial sectional elevation; Figure 2 a
partial plan; Figure 3 details of the bank guard; Figures 4, 5 and 6 details of the
arrangement for lifting the hanks bodily over the edges of the vats and for securing
their immersion therein.
In each of the Figures similar letters of reference are employed to indicate similar
parts or details of construction.
In the drawings Figures 1 and 2, and in the detail drawings, only one set of rollers
is indicated and I will hereinafter limit my description to one such set; this
elementary representation and description being adopted for the sake of greater
simplicity and clearness, but it will be understood that as many sets of the rollers
and accessories as may be required and as are convenient may be employed.
The top roller or bowl A has its bearings in a frame which is suspended by the
links B to a lever C carried by suitable fixings D D and provided at one end with an
anti-friction roller E. At that part of the circular path of the anti-friction roller E
opposite to the point at which it is proposed to take off and replace the hanks, I fix.
by suspension from beams or by other suitable means, a double ramped path F con-
sisting of an inclined plane up which the roller E travels to the level part. F¹ and a
similarly inclined part F2 down which the roller travels from the part F¹.
In travelling up the inclined plane the roller E lifts the lever C and thereby
automatically lifts the roller A suspended therefrom. Whilst the anti-friction roller
is traversing the level part of the path F the roller A is maintained in the lifted
position and during this time, the attendant who stands opposite, takes off the finished
hanks and replaces them with fresh ones. Thereafter, the anti-friction roller travels
down the inclined part F2 and thus lowering the lever, brings the top roller A again
into contact with the hanks on the lower roller.
In order to prevent the hanks from running off the bottom roller, I provide the
guard G which is constructed and arranged in such a manner as not to offer any
obstruction to the attendant in removing and replacing the hanks. This guard is
shewn on an enlarged scale in Figure 3, and it consists of a rod G pivoted at I to a
bracket or fixing on the roller framing, and bent or curved at its lower end so as to
come under the bottom roller. In the upper part of the guard there is a pin which
passes through slots J formed in the lower end or jaws of the link H the upper end
of which is connected to the lever C. The object of the slots J in the link H is to
permit the top roller to be lifted to a slight extent if required in passing over either
of the vats without actuating the guard. In the last vat for example, which generally
contains clear water, it is desirable that the yarn should be opened out and thoroughly
rinsed, and for this purpose the nip or weight of the top roller is taken off. The lift
given to the roller in this case is not however sufficient to cause the guard pin to
bottom the slot J, and consequently the guard is not lifted or moved. When how-
ever the lever C is lifted by the anti-friction roller E traversing the double ramp F,
the link J. is lifted and the pin comes into contact with the bottom of the slots J,
the guard is thus lifted into the position indicated by the dotted lines where it will be
out of the way of the attendant. As soon as the anti-friction roller has passed the
double ramp, the guard will be restored to its normal position.
I have represented the anti-friction roller as being fixed upon the inner end of the

page_text: lever C and I prefer to employ it in this position, but if desired it may be arranged
elsewhere thereon as may be convenient, as for example on the outer end, in which
case it will be understood that the double ramp F must be arranged below the anti-
friction roller.
The details of the arrangement for lifting the hanks over the top edges of the vats
or over their partitions are illustrated by Figures 4, 5, and 6.
To a suitable and convenient part of the revolving table P, I fix a bracket K
carrying a stud upon which is pivoted the lever L, which carries at its opposite end
one or more brass wooden or other incorrodible winches M M, and an anti-friction
roller N.
When banks of uniform and fixed lengths have to be treated, I attach to the inside
plate of the vat or to the sides or dividing partitions as the case may be, a curved
switchback" path O for the anti-friction roller N as shewn in Figures 4 and 5.
The horizontal portions of the track O which are below the surface of the liquor are
arranged at such a depth or distance from the top edge of the vat as will cause the
full weight of the lever Land of the winches M to come upon the hanks and thus
cause them to be immersed to the proper distance in the liquor and prevent their
floating or becoming knotted twisted or entangled. It is understood that during
their treatment the hanks pass between the rollers A A' and around the winch or
winches M. Should there be no hanks on the rollers the anti-friction roller N
will travel on the switchback path and the lever L will thus be prevented from
swinging.
When the apparatus is required to operate with hanks of different lengths, I
dispense with that part of the switchback path O which is between the ends of the
inclined plane on the lifting or approach side, leaving only the lifting part of the path
as shewn in Figure 6. To the roller end of the lever L, I connect a chain or cord
the other end of which is connected to the travelling table in such a manner that the
amount of drop of the lever and winches may be adjusted to suit the various lengths
of the different hanks. In this case the winches instead of being supported by the
anti-friction roller N on the curved path O, are supported by the chain cord or similar
device.
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,
(1) In apparatus of the type set forth for dyeing washing and finishing yarn in
hanks, the means for automatically lifting and lowering the top roller A; constructed
and arranged substantially as herein before described and as illustrated by Figures 1
and 2 of the accompanying drawings.
(2) In apparatus of the type set forth for dyeing washing and finishing yarn in
