PROVISIONAL SPECIFICATION.
Improvements in Machines for Washing, Scouring, Mordanting,
Bleaching, Sizing, and Dyeing Yarn in the Hank.
We. JOSEPH SPENCER LORD, and GEORGE SPENCER LORD, both of Victoria
Engineering Works, Stanley Street, Whitefield, in the County of Lancaster,
Engineers, do hereby declare the nature of this invention to be as follows:-
This invention has for its object an improved and simplyfied construction of
machine for washing, scouring, mordanting, bleaching, sizing, and dyeing yarn in
the hank whereby such operations are performed similarly as by hand but at a
much greater speed and more uniformly and the ends of the banks are not liable to
get entangled.
This invention comprises, firstly, an improvement in the crank motion used for
lifting and lowering the hank frame for which Samuel Spencer has obtained Letters
Patent No. 12652, dated August 13th 1890; secondly, means for assisting the
raising and lowering of the said frame; thirdly, means for turning the hauks over
intermittently and uniformly; fourthly, means for facilitating the placing and
removal of the hanks in and out of the machine respectively.
To this end we employ, at the back of the vat of the machine to rotate upon
studs, two worm wheels, each of which is in gear with a worm fixed проп the
driving shaft mounted in suitable bearings at the back of the vat, similarly as
described in the Specification belonging to the Patent aforesaid. However,
instead of forming the said worm wheels and worms both one hand we use a right
and a left hand worm wheel and worms so that the crank studs or bowls rotate two
and from each other and thus act upon the rail of the hank frame centrally
whereby the friction between the worms and worm wheels is reduced to a minimum
and thus power saved and in lien of employing only one of the said crank studs or
bowl two may be employed on each of the said worm wheels so as to render the
same double lifting in one revolution. in order to still further facilitate the
raising and lowering of the bank frame we employ at each end thereof a balance
weight which act in unison with each other.
In this machine the bank frame consists of a rail supported by two vertical
shanks mounted in suitable bearings at the back of the vat and tied together by a
rail acted upon by the aforesaid crank studs or bowls which cause the frame to rise
and fall similarly as described in the Specification belonging to the aforesaid
Patent. However in lieu of employing on the said rail bracket carrying roller or
fallers we fix upon the same at suitable distances apart from each other brackets
carrying rods extending across the vat. In connection therewith we employ in
suitable bearing upon the back of the rat a rail carrying other rods adapted to
slide or traverse longitudinally to and from the first named rods upon which rods
the hanks are placed. The traverse or longitudinal movement of the said rod rail
may be effected in one direction by means of a cam fixed upon one of the aforesaid
worm wheels and a lever and in the other by a weight or spring or in lieu of the
latter a cam and lever may also be used and thus the movement of the rail
rendered positive in both direction.
The front end of the said traversing rods are arranged to rest upon a rail carried
by pulleys mounted on the front of the vat the two end rods and one or more
between the same, being adapted to engage in recesses formed in the said rail, so
as to cause it to move reciprocally with the said rods and thus reduce friction
between the ends of the said rods and the rail or vat on the traverse of the former.

page_text: Owing to the continuous rise and fall of the one set of the said rods and the
lateral reciprocal movement of the other set, the bank is gradually turned and
raised and lowered in the liquor in an alternate and uniform manner.
In lieu of imparting a turn to the hank, in amount equal to the longitudinal
movement or traverse of the said rods, we may employ at the end of the traverse of
each of the said rods, other rods loosely placed into recesses in the
top of the vat,
so as to cause the hank to be nipped between the traversing rods and the stationary
rods, whilst the other rods rise and thereby impart a larger amount of turn to the
hank than the traversing rods would be capable of imparting in a given space.
In order to permit of lifting the said rods in order to facilitate the placing and
removal of the hanks the said rail is rendered partially rotary movable in its
bearings by means of two hand levers secured upon the said rail one at each end
thereof which are retained in position when lifted by means of legs pivoted to the
ends of the vat.

Improvements in Machines for Washing, Scouring, Mordanting,
Bleaching, Sizing, and Dyeing Yarn in the Hank.
We, JOSEPH SPENCER LORD, and GEORGE SPENCER LORD, both of Victoria
Engineering Works, Stanley Street, Whitefield, 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 :-
This invention has for its object an improved and simplyfied construction of
machine for washing, scouring, mordanting, bleaching, sizing, and dyeing yarn in
the hank whereby such operations are performed similarly as by hand but at a much
greater speed and more uniformly and the ends of the hanks are not liable to get
entangled.
This invention comprises, firstly, an improvement in the crank motion used for
lifting and lowering the bank frame for which Samuel Spencer obtained Letters
Patent No. 12652, dated August 13th 1890; secondly, means for assisting the
raising and lowering of the said frame; thirdly, means for turning the banks over
intermittently and uniformly; fourthly, means for facilitating the placing and
removal of the hanks in and out of the machine respectively.
And in order that our invention may be more fully understood we have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a front view, Fig. 2 a back view, Fig. 3 an end view and Fig. 4 a
sectional end view. Figs. 5 & 6 are respectively a detached front view and an eud
view, and Figs. 7 & 8 diagrams of a machine for washing, scouring, mordanting,
bleaching, sizing and dyeing yarn in the hank constructed in accordance with our
invention.
In carrying out our invention and referring to Figs. 1, 2, 3 & 4, we employ at
the back of the vat a of the machine to rotate upon studs b, see more particularly
Fig. 3, two worm wheels c, each of which is in gear with a worm d fixed upon the
driving shaft mounted in suitable bearings similarly as described in the
Specification belonging to the Patent aforesaid. However, instead of forming
the worm wheels c and worms d both one hand, we use a right and a lelt hand
worm wheel and worms corresponding therewith, so that the crank studs or bowls c
rotate to and from each other and thus act upon the bank frame centrally whereby

thus power saved.
unison with each other.
In lieu of employing only one of the said crank studs or bowls, two may
be employed on each of the said worm wheels so as to render the same double
lifting in one revolution as will be readily understood. The said hank frame
consists of the back rail g, the end rails g¹ and the front rail g³, the end rails g
being stayed by means of rods and the front rail g³ rendered removable to
facilitate the placing and removal of the hanks. In order to still further facilitate
the raising and lowering of the bank frame we connect to each end rod gl by means
of a chain a balance weight riding over a pulley h2, which weights act in
The said hank frame is supported by two vertical shanks mounted in suitable
bearings at the back of the vata and tied together by the rail g acted upon by
the crank studs or bowls c' which cause the frame to rise and fall similarly as
described in the Specification belonging to the aforesaid Letters Patent. However
in lieu of employing on the rail g brackets carrying rollers or fallers as heretofore
we fix upon the same at suitable distances apart from each other rods / with or
without rollers l'extending across the vat a, the front ends of which are supported by
the front rail g². In connection therewith we employ in suitable bearings m upon
the back of the vat a, a rail n carrying other rods o adapted to slide or traverse
longitudinally to the vat a to and from the rods or rollers upon which rods or
rollers the banks al are placed, see more particularly Figs. 1, 5 & 6. The traverse
or longitudinal movement of the rod rail n may be effected in one direction by
means of a cam c² fixed upon one of the worm wheels c and a lever o one end of
which engages the rod rail n and the other being acted upon by the cam ♂ and in
the other direction by a weight p or spring; or, in lieu of the latter, a second cam
and lever may be used similarly as already described and thus the movement of the
rod rail n rendered positive in both directions.

The front end of the traversing rods o may be arranged to rest upon a rail
see Figs. 1, 2 & 4, carried by pulleys q' mounted on the front of the vat a the
two end rods and one or more between the same, being adapted to engage in
recesses o¹ formed in the rail g, so as to cause it to move reciprocally with the rods o
and thus reduce friction between the ends of the rods o and vat on the traverse of the
former which would be the case otherwise particularly when treating large hanks.
In some instances however the rail q may be dispensed with and the rod ends
arranged to slide upon the vat or be positioned a little above the same.
Owing to the continuous rise and fall of the rods or rollers and the lateral
reciprocal movement of the rods o the bank a' is gradually turned and raised and
lowered in the liquor in an alternate and uniform manner.
The relative position of the bank frame and the traversing rods o shown in
Figs. 1, 2, 3 & 4 is that, after the rods o¹ have moved to the right and turned the
hanks a' and the hank frame commences to raise the hanks a into the position
shown in dotted lines in Fig. 1.
In lieu of imparting a turn to the bank, in amount equal to the longitudinal
movement or traverse of the rods we may employ at the end of the traverse of each
of the rods o, other rods r, see Figs. 5, 6 & 8, loosely placed into recesses in the
top of the vat a, so as to cause the hank to be nipped between the traversing rods o
and the stationary rods r whilst the rods or rollers rise and thereby impart a
second and larger turn to the hank a' than the traversing rods o alone would be
capable of imparting in a given space. In order to prevent the rods being lifted
when raising the hanks a, we employ a readily removable rail over the front
ends thereof secured in brackets u fixed to the vat a.
In order to permit of lifting the rods o to facilitate the placing and removal of
the hanks a' the rail n is arranged to turn in its bearings in by means of a hand
lever secured upon one end of the rail n which are retained in position when
lifted by means of a catch or other suitable means such as a leg pivoted to the ends
of the vat.

page_text: To the back of the vat a we pivot a hand levert the lower end of which is
furnished with an anti-friction bowl t¹ and which when depressed comes into
contact with the hank frame rail whereby the hauk frame y can be lifted into
the position, shown in dotted lines, Fig. 3, for the purpose of removing the treated
hanks and substituting the same.
In lieu of the said lever suitable gearing may be employed to raise the hank
frame g for the purpose described.
The brackets u have down the front of the vat a hook shaped projections u
adapted to receive the front rail 92 and the rod whilst removing the hanks.
Fig. 7 shows the various positions the hank and rods will take up when the
machine described is constructed to subject the hanks to a single partial turn
during one rise and fall of the hank frame. I represents the normal position of
the hanks a', riz. when the (hank) frame is in its lowest position and the rod o below
the rod or roller ; II after the hank has received a partial turn through the
traverse of the rod o and III after the hanks have been raised, from whence the
hank frame and the rods o return. again to their normal position 1.
Fig. 8 shows the various positions the hank and rods or rollers and rods o & r
will take up when the machine described is constructed to subject the hanks to a
double partial turn during one rise and fall of the hank frame. I represents their
normal position; II after the traverse of the rod o, first partial turn and the nipping.
of the hanks has been effected and III after the hanks have been raised and turned
a second time, from whence the hank frame and the rods o & return again to
their normal position I.

It will be readily seen that on the traverse of the rods o besides turning they
drag the hank over the rods or rollers l' and when raised by the latter over the
rods which has the effect of pressing the liquor uniformly through the fibres of
the hank a which effect is increased by the employment of the stationary or
nipping rods and which arrangement is specially applicable for dyeing large and
heavy hanks such as wool, jute, and which will also effectively keep the ends straight
and prevent the same becoming entangled.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim, is-
"In machines for washing, scouring, mordanting, bleaching, sizing and dyeing yarn
in the hank,"
1st. In combination with a bank frame adapted to be raised and lowered by crank
studs or bowls, the employment of right and left hand threaded worms d in pairs
in connection with correspondingly toothed worm wheels c carrying the said crank
studs or bowls in such a manner that the latter will revolve in opposite directions,
substantially as and for the purpose set forth.
2nd. In combination with a rising and falling hank frame carrying rods or
rollers, laterally movable rods o adapted to impart a partial turn to the hanks,
substantially as and for the purpose set forth.
3rd. In combination with the laterally movable rods o, specified in the preceding
claim, a corresponding number of stationary rods between which the banks are
nipped so as to have imparted a second partial turn during the rise of the hank
frame, substantially as and for the purpose set forth.
4th. The rod rail n adapted to partially turn in its bearing so as to enable to raise
the front end of the rods o, all substantially as and for the purpose set forth.
