Improvements in Hank Dyeing Machines.
I, JOSEPH WILBY CROWTHER, of Gawthorp Green, Kirkheaton, in the County
of York, Dyer, do hereby declare the nature of this invention to be as follows:
This invention relates to machines for dyeing hanks and consists of improved
apparatus constructed so as to provide for the supply of hanks to the vats, and
to effect the automatic transfer of such hanks from vat to vat throughout the
series of vats and to deposit said hanks when dyed upon a delivery creeper or
receiver.
According to this my said invention there is provided an endless chain ex-
tending the length of the several vats and said chain at intervals is provided
with pins which engage with and traverse the hank rods forward in their
end supports until the hanks arrive at nearly the end of the vat when a vertical
endless chain (one on each side of the tank) engages with the hank rods and
lifts the latter out of the vat and conveys said rod and hank over and into the
adjoining vat after traversing which they are in like way and by like means
litted and transfered to a third vat and so on to and through the whole series
of vats whereon at the exit end of the last vat the rods and hanks are lifted
by endless creeper chains out of the vat ready for removal.
The rollers in the vat I prefer should have a reversing motion which may be
effected by means of clutch gear, screw and rack, or like means, and the rollers
are divided longitudinally, into say four lengths, by flanges so as to keep the
several hanks from contact and crowding on each other so as to expose the yarn
in an open state to the action of the dye liquor.

I, JOSEPH WILBY CROWTHER, of Gawthorp Green, Kirkheaton, in the County
of York, Dyer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascer
tained in and by the following statement:-
This invention relates to improvements in hank dyeing and like machines
such as scouring machines, and consists of improved apparatus constructed to
provide for the supply of hanks to the vats, to effect the automatic transfer of

page_text: next bearing block 6 with its roller 7 into line with the chain 17 so that the
next hook 18 will take the roller 7 round the elevator and deposit the same on
one of the bearing blocks and carry it through the vat, the feeding device
is also provided with a rack 10" which causes the pinions 9 and rollers 7 to
revolve whenever the chain 3" is operated.
An elevator arrangement may also be used at the delivery end as shewn in
Figs. 1 and 2, but in this case the chain 17 travels over the pulleys of two sets
of uprights 14 and the rollers with the treated hanks are removed by hand on
the hooks bearing them bringing them within reach. Or the same arrange-
ment as shewn in Fig. 4 may be applied to the end of the delivery elevator in
Fig. 1 for taking the rollers off the chain, by applying this device several
rollers with their hanks might be removed at once without waiting for each one
to come within reach of hand.
The hanks as they pass through the vats are subjected to a rotating motion
and a reversal of same by means of the pinions 9 and racks 10-11, the wheel 12
of which latter is given a to and fro reversing motion at intervals by any suit-
able means such as a mangle wheel indicated at 29 and carried on shaft 12ª
and the clutches 30, 30 on the main shaft 31 in the usual manner. The
mechanism for driving however may be varied. For driving the chains 3 I
employ the bevel gear 32 on the main shaft, which engages with bevel gear 33
and drives through a worm and worm wheel 34 a shaft 35 on which the sprocket
wheels 5, 5 are carried.
For driving the shaft 22 I employ as stated the bevel gears 23-24 on shaft 25
which is driven in turn by a train of gears 36, 37, 38 and 39.
In operation the hanks and rollers are placed on the feeding device shewn in
Fig. 4 at the entering end of the machine, or directly on the bearings of the
chain 3, and thence travel through the first tank, they are then taken by the
elevating device at the end of the first tank, removed from the first tank, placed
on the chain again, carried through the second tank, having a reversing motion
given to them while in both tanks, taken by the delivery elevation out of the
last tank, carried over the driving mechanism, and collected from the delivery
device by hand.
By the reversal of the motion of the hanks in the liquor of the tanks, a more
complete impregnation of same is effected.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
(1) In a hank dyeing and like machine, the combination with a tank, of
means for giving the hanks a movement and a reverse movement when in the
liquor of same, as herein described & substantially as illustrated by the annexed
drawings.
(2) In a hank dyeing and like machine, the combination with a tank of
means for giving the hanks a movement of rotation and a reverse movement in
same, and means for carrying said hanks through the tanks, as herein described
& substantially as illustrated by the annexed drawings.
(3) In a hank dyeing and like machine, and in combination, a tank, endless
chains on each side of same, rods for supporting the hanks, means carried by
the chains for supporting the rods, and means for driving the chains, as herein
described & substantially as illustrated by the annexed drawings.
(4) In a hank dyeing and like machine and in combination, a tank, endless
chains on each side of same, rods for supporting the hanks, bearings carried
by the chains for supporting the rods, means for placing said rods and hanks
on the bearings of the chain at the entering end of the machine and means
for driving the chains, as herein described & substantially as illustrated by the
annexed drawings.
(5) In a hank dyeing and like machine the combination with a plurality of
