IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN THE DYEING SIZING
AND WRINGING OF HANKS
"
My Invention consists of improvements on letters patent of Mason and Conlong
No 375 1879 and relates to apparatus employed in the dyeing sizing and wringing
of hanks in dyeing or sizing operations and has for its object in the first place to
effect the rotation, dwell and reversal of rotating hooks that is to say-it is required
that the said rotation shall be intermittent producing intervals of rest between the
rotations. To effect this I employ a double internal segmental spur wheel having
cast or formed on each side of its plate segmental rims concentric with the
boss and internal rim of the wheel being of a radius less than the internal rim and
greater than the boss, the segments on the two faces of the said wheel are not
equal and are formed in different relative positions to each other whereby we
obtain two rotations of one revolving hook and three or more rotations of the
other during the rotation of one hook the other is stationary there being two hook
shafts and one driving shaft the pinion on the hook shafts being alternately in
action. The bank is looped by one end onto the said rotating book the other
end being looped onto a sliding hook formed with a square shank to slide in a bush
This shank is drilled
carried by a bracket bolted to the opposite side of the vat.
with one or more holes to receive a pin which pin bears against the bush and
regulates the amount of drawing in of the hook the said shank also supports a
weight by means of a chain riding over a small pulley supported by a bracket.
The machine when made for sizing and wringing hanks is built up of two separate

page_text: but combined vats one of which is employed for washing and wringing-off and the
other vat for finishing and the same arrangement of hooks is employed to each vat.
The said rotating hook of the washing-off vat is caused to make two rotations in
one direction to wring out the required amount of superfluous size from the hank
and then in an opposite direction to untwist the hank after which the hook is
caused to make a short dwell and the hank is removed. The teeth on each rim of
the said double internal segmental spur wheel rotates each pinion on the shank of
each rotating hook in alternation that is to say during the time one pinion is
being rotated the pinion of the other will be at rest and vice versa, also the teeth
on each said concentric segment will act in alternation upon each hook pinion so that
a reversing motion is obtained for each hook from the one wheel which we consider
is an advantage the said double internal spur segment wheel along with its shaft
being rotated by means of a worm on a driving shaft gearing into a worm-wheel
cast on the periphery of the said internal segment wheel and rotating the latter
wheel constantly in the one direction We form the said internal segmental spur
wheel with less than the full complement of teeth and form surfaces upon it and
the pinions which surfaces meet at suitable times when the said dwells are to occur
in order to prevent any revolution of either pinion and rotating hooks at such times.
My Invention relates in the second place to a novel arrangement for removing the
bank from off the hooks after it has been twisted and unwrung. To this end we
mount on one side of the vat say the washing-out vat an endless chain carrying on
each side a radial bent arm. When the said apron is actuated by means of chains
driven from a shaft on which a pinion is fixed and geared into by the herein before
mentioned worn-wheel on the periphery of the internal segment wheel the said
radial arms bear on the under part of the hank and lift it onto the travelling apron
from whence it falls into a box placed to receive it, during the time the radial arms
are taking-off the bank the rotating hook is caused to dwell by the means herein-
before mentioned. The operation of the machine is as follows:-The hank after
being washed through the size in one vat is placed on the stationary and rotating
hooks by the attendant during a dwell of the latter hook the segment teeth on the
internal rim on one side of the said segmental wheel rotates the pinion on the
hook shank and thereby the hook for say two turns when the said seginent teeth
pass out of gear with the pinion and the plain surfaces of the wheel and pinion
meet and further rotation of the hook is prevented for a short interval to enable
the attendant to wipe-off the size the said concentric segment rim now engages
with the pinion and reverses it to unwring the hank from whence it is removed
The said internal segmental wheel acts upon in a like manner the rotating hook of
the other vat in which the hanks after being stoved are again sized and wrung in
which case the bank is wrung up tighter by rotating the hook say for example three
times. A reel or reels being mounted to the vat on which reel the bank is hung
and rotated through the size by means of a driving-band pressing over a grooved
pulley on the worm shaft and a second grooved pulley on the reel shaft. We have
described the Invention as applied to the sizing and wringing of hanks but it may
also be applied to the dyeing and wringing of indigo and fancy hanks.

SAMUEL SPENCER of Radcliffe Bridge in the County of Lancaster Engineer
"IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN THE DYEING, SIZING
AND WRINGING OF HANKS
"
This Invention consists of apparatus employed in the dyeing, sizing and
wringing of hanks in dyeing or sizing operations and has for its object to effect
the rotation dwell and reversal of the rotating hooks and to effect the removal of
the hanks from the hooks. I employ a double internal segmental spur wheel having
cast or formed on each side spur segments which are concentric with the axis of
the wheel external and internal segments gearing alternately with pinions on the
hook spindles whereby the hooks are caused to rotate in opposite directions to twist
and untwist the hanks. The hooks are caused to dwell after each movement by
means of curved surfaces which prevent the rotation of the said pinions. The hank
is removed from the hooks by means of fingers attached to a travelling apron which
receives the hank and delivers it into a receptacle.
In order that this invention may be fully understood I have attached hereunto a
sheet of drawings made to a scale of about one and a half inches to the foot and
illustrative of a sizing machine constructed in accordance with the invention. In
the said drawings Fig 1 represents a sectional elevation and Fig 2 a plan of the
machine Fig 3 being a detached view of the reversing motion. In the said Figs
or in some of them A, B, are two vats or cisterns of an ordinary or suitable
construction between which cisterns is mounted the reversing motion C. A worm
wheel c is mounted upon a shaft d which is secured in a framing e which is fixed
to the two vats. A worm ffixed or formed upon a shaft g gears with the said worm
wheel and the said shaft is provided with fast and loose strap driving pullies h
whereby the worm wheel is caused to revolve. The wheel c is formed or provided
on each side with a segment of internal spur teeth i and with a segment of external
spur teeth k. These segments engage alternately with spur pinions on the spindles
of the hooks m, m whereby the said hooks are caused to rotate first in one direction
and then in the other the segments on one side of the wheel driving one hook and
the segments on the other side driving the other hook. On each side of the wheel
are cast or fixed curved surfaces or segments without teeth n and o. One of
the teeth in each pinion is shorter than the others and the parts are so proportioned
as that at each dwell of the hook the short teeth shall be opposite to one or the
other of the two segments n, o as represented in Fig: 3. In this case the said short
tooth enables the segment n to come into contact or nearly into contact with the
tooth which is on each side of the short tooth so that the pinion is prevented from
turning until by the rotation of the wheel the said segment has passed away so as
to leave the pinion free to turn. The shroud of each pinion is formed with a tooth
with which a projection on the wheel comes in contact at the required times to start
the rotation of the pinion but this may be dispensed with if not considered to be
necessary. A pinion p fixed on a shaft q gears with the teeth of the worm wheel o
and on this shaft and upon two carrier rollers is mounted an endless apron 8.
To this apron are fixed two curved fingers t, t seen in Fig. 4 which is a sectional
view of the said apron. The rotation of the shaft 9 causes the apron to have a
travelling motion and the parts are so proportioned as that during each dwell of
the hook after the untwisting movement the fingers t come below the hank as in
Fig. 4 and lift the hank off the hooks. By the continued movement of the apron
the hank is carried over the edge of the vat and is deposited in a receptacle which

page_text: may be conveniently placed to receive it. The action of the machine is as follows.
The worm wheel c rotates continuously in one direction and the hooks are revolved
by the action of the teeth i in one direction to wring the hanks. The segments o
then hold the pinion to give the dwell of the hooks to allow time for the wiping
off. The books are then rotated in a reverse direction by the action of the teeth k
to untwist the hanks. The hooks then make a longer dwell during which the
pinions are held by the longer segments n the hanks being removed and replaced
with fresh hanks during this interval. The removal of one hank is effected by hand
the other hank being removed by the action of the apron as hereinbefore described.
In the example the vat B is supposed to be for sizing and the vat A for "washing
off" but this will be varied according to the use for which the machine is intended
and in some cases one or both of the vats will contain dye. I may apply a taking-
off apron to both vats instead of to one only. The spur segments are by preference
so situated on the wheel c as that one hook shall commence to rotate a little before
the other or they may be so arranged as that one hook shall be twisting whilst the
other is untwisting. The machine is provided with bobbins u to hold hanks as is
usual these bobbins receiving a revolving motion from the driving shaft.
Having now fully set forth and indicated the nature of the said Invention and
the manner in which I carry the same into practical effect I wish it to be distinctly
understood that I lay no claim to either of the herein before described parts of my
invention separately but what I do claim and desire to have secured to me by the
herein before mentioned Letters Patent is the combination only of the wheel c with
its internal and external spur segments and its holding segments n, o with the
travelling apron and fingers for removing the hanks, substantially as and for the
purposes set forth and indicated hereinbefore and in and by the accompanying
drawings.
In witness whereof I the said Samuel Spencer have hereunto set my hand
and seal this twenty-seventh day of March in the year of our Lord one
thousand eight hundred and eighty-three.
