Sections 18 to 21 of the Patents, Designs, and Trade Marks Act, 1883.
We, KENYON LOCKWOOD, of the firm of Lockwood Brothers, of Lee Mills,
Hepworth, near Huddersfield, Yorkshire, Manufacturers, and ELLIS LEE ADAMSON of
the same place, Dyer, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to machines for dyeing yarns and consists in the method of
and means for immersing each portion of the yarn in the dye liquor in such a manner
that an equal shade of colour is obtained throughout the whole of the yarn being
dyed; also in the method of and means for traversing the yarn backwards and
forwards through the dye liquor in order that the liquor may penetrate to the inner
or covered portions of the yarn.
Hitherto the method of dipping and traversing the yarn in the dye vessel has been
effected by hand labour, but it is our intention to effect it by mechanical means.
In order to carry out our invention we employ a stationary rack extending across
the top, or near the top, of the dye vessel, into the teeth of which rack, gear a number
of pinions supported by a suitable cover which is capable of sliding endwise across
the dye vessel. The shaft of each pinion is sufficiently long to allow of one or more
creels or bobbins being placed on each end thereof. The yarn to be dyed is placed
partially around the creels, and that portion of yarn which is not around the creel is
submerged in the dye liquor. A "to and fro" motion is then given to the sliding
cover by any suitable means, which draws the yarn through the liquor, first in one
direction and then in the other, thereby forcing the liquor into and through the yarn,
so that each portion thereof is thoroughly dyed; in addition to this, the end wise
movement of the sliding cover.causes the pinions, by reason of the rack, to be rotated
first in one direction and then in the opposite direction, whereby the yarn is partially
rotated, and this is continued until the yarn is sufficiently dyed, when the rack and
pinion and parts connected therewith can be raised by means of screw or other known
devices, for the purpose of lifting the yarn out of the liquor.

page_text: By the means above set forth, a considerable saving of time is effected, whilst an
equal shade of colour can be obtained on each portion of the yarn being dyed, which
is not the case with the present method of dyeing yarns.

As for Dyeing Yarns.
We, KENYON LOCKWOOD of the firm of Lockwood Brothers of Lee Mills,
Hepworth, near Huddersfield Yorkshire, Manufacturers, and ELLIS LEE ADAMSON of
.the same place Dyer, 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 :-
Our invention relates to machines for dyeing yarns and consists in the method of
and means for immersing each portion of the yarn in the dye liquor in such a manner
that an equal shade of colour is obtained throughout the whole of the yarn being
dyed; also in the method of and means for traversing the yarn backwards and
forwards through the dye liquor in order that the liquor may penetrate to the inner or
covered portions of the yarn.
Hitherto the method of dipping and traversing the yarn in the dye vessel has been
effected by hand labour, but it is our intention to effect it by mechanical means.
In order to carry out our invention we employ a stationary rack extending across
the top, or near the top, of the dye vessel, into the teeth of which rack gear a number
of pinions supported by a suitable cover which is capable of sliding end wise across the
dye vessel. The shaft of each pinion is sufficiently long to allow of one or more
creels or bobbins being placed on each end thereof. The yarn to be dyed is placed
partially around the creels, and also around a set of creels submerged in the dye
liquor. A "to and fro" motion is then given to the sliding cover which causes the
pinions, by reason of the rack, to be rotated first in one direction and then in the
opposite direction, whereby the yarn is partially rotated, and made to travel which is
continued until the yarn is sufficiently dyed, when the rack and pinion and parts.
connected therewith can be raised out of the dye liquor by means of screw or other
known devices.
In order that our invention may be better understood we herein make reference to

page_text: the accompanying sheet of Drawings wherein Fig. 1 is longitudinal section of appa-
ratus constructed according to our invention and Fig. 2 is sectional plan view taken
through the line a-b of Fig. 1. I represents the dye cistern at the top of which
are two horizontal bars 2 connected together by crossbars 3, which crossbars carry a
long toothed rock 4. The several parts thus mentioned carry brackets à, connected
bolted to brackets 22 at each end of the cistern and connected together by cross bars 3 to
which is cast or otherwise secured the long toothed rack 4. 5 are brackets bolted to
framework 20 connected together by stud 6 for the purpose of receiving one end
of a connecting rod 7, the other end of such connecting rod being attached to the
upper end of the bell crank lever 8 hinged at 9 whilst the lower end of the bell crank
lever connected by vertical rod 10 to one arm of the spur wheel 11 driven by
pinion 12 from the main driving shaft 13 so that as the main driving shaft revolves,
rotary motion is given to the spur wheel 11, which gives upward and downward motion
to the vertical connecting rod 10 and consequently to the bell crank lever 8, thereby
giving to the connecting rod 7 a horizontal reciprocatory motion earrying the toothed
rack 4 backwards and forwards. A number of pinion wheels 14 are a number of
pinion wheels 14 are carried by the framework 20 and placed in gear with the underside
of the rack, the axle of such pinions being extended to both sides of the pinion wheels,
upon which shaft are placed creels or bobbins 15 and underneath each creel or bobbin
are corresponding creels or bobbins 16, carried by the vertical slotted bars 17, and
around these upper and lower creels or bobbins, hanks of yarn 18 are placed, such
hanks being kept at a suitable tension by the lower bobbins 16, which are capable of
being adjusted in the slots of the vertical arms 17. It will be seen that as the toothed
rack 4 is made to reciprocate backwards and forwards as previously explained, the
axle of the pinion wheels 14 will be caused to revolve and consequently the ereels
or bobbins, by which means every part of the banks of yarn is in turn immersed
in the dye liquor, consequently the said hanke are evenly and uniformly dyed.
framework 20 is made to reciprocate the pinions 14 which are in gear with stationary
rack 4 will be caused to revolve and consequently rotate the creels or bobbins, 15, 16
whereby each portion of the yarn is equally immersed in the dye liquor thus enabling us
to dye the whole of the yarn one equal shade.
In order to prevent the rack rising out of contact with the pinions, we arrange.
grooved pulleys 10 carried by brackets 20 projecting from the framework 20 cuch
grooved pulleys resting on the top of the horizontal bars 2 as shown in cross section
Fig. 3 so that it becomes impossible for the rack 4 to be lifted out of gear with the
pinion wheels 14.
19 are grooved pulleys carried by brackets 5 and so bolted to framework 20 such
grooved pulleys resting on the top of the horizontal bars 2 as shown in cross section Fig. 3
for carrying and supporting the pinions 14 and framework 20 and for lessening the
friction between the parts when traversing to and fro.
When the hanks of yarn have been sufficiently dyed and it is necessary to remove
them out of the dye vessel and substitute others, we employ special apparatus for this
purpose, comprising vertical pillars 21 upon which pillars, are placed metal bosses 22
to which metal bosses the horizontal bars 2, are connected by bolts or other suitable
means. To these bosses 22 is connected one end of the chain 23, which chain is made
to pass around grooved pulleys 24 and 25, the opposite end of such chain carrying a
weight 26. Upon the axle of the grooved pulleys 24 are fixed worm wheels 27, in
gear with worms 28 on the horizontal shaft, so that on the operator turning the hand
wheel 29, the worms and wheels are caused to revolve, in doing which the grooved
pulleys 24 are also made to revolve in such a manner that the whole of the parts
comprising the racks and pinions and wheels together with the bobbins, are raised out
of the dye vessel for the purpose of permitting the hanks to be changed and on the
hand wheel being turned in the opposite direction the several parts are lowered and
again immersed in the liquor. By the employment of the apparatus as herein
described, considerable saving of time is effected in the dyeing of hanks of yarn,
whilst a more equal shade of colour can be obtained in the said yarn which we find
is not the case with the method at present in use.

page_text: Having now particularly described and ascertained the nature of our invention,
and in what manner the same is to be performed we declare that what wo
claim is :-
Firstly In a machine for dyeing hanks of yarn the combination therewith of
racks and pinions for causing hanks of yarn to travel through the dye liquor in manner
substantially as shewn and described.
Secondly-In a machine for dyeing hanks of yarn the combination therewith-of
the reciprocatory rack 4 for purposes set forth.
Thirdly-Secondly-The general combination and arrangement of mechanism
comprising a machine substantially as herein shewn and described for dyeing hanks
of yarn.

Improvements in the Method of and Means for Dyeing Yarns.
.
We, KENYON LOCKWOOD of the firm of Lockwood Brothers of Lee Mills,

In order that our invention may be better understood we herein make reference to
the accompanying sheet of Drawings wherein Fig. 1 is longitudinal section of appa-
ratus constructed according to our invention and Fig. 2 is sectional plan view taken
through the line a-b of Fig. 1. 1 represents the dye cistern at the top of which
are two horizontal bars 2 connected together by crossbars 3, which crossbars carry a

catory motion carrying the toothed rack 4 backwards and forwards. A number of

be caused to revolve and consequently the creels or bobbins; by which means every
part of the hanks of yarn is in turn immersed in the dye liquor, consequently the said
hanks are evenly and uniformly dyed.
In order to prevent the rack rising out of contact with the pinions, we arrange
grooved pulleys 19 carried by brackets 20 projecting from the framework 20 such
grooved pulleys resting on the top of the horizontal bars 2 as shewn in cross section
Fig. 3 so that it becomes impossible for the rack 4 to be lifted out of gear with the
pinion wheels 14.
When the hanks of yarn have been sufficiently dyed and it is necessary to remove
them out of the dye vessel and substitute others, we employ special apparatus for this

described, considerable saving of time is effected in the dyeing of hanks of yarn,
whilst a more equal shade of colour can be obtained in the said yarn which we find
is not the case with the method at present in use.
