Improvements in Machinery for Dyeing, Sizing and Washing Hanks
of Yarn and Slubbing.
We, WRIGHT WOODCOCK, and JESHURUN LONGTHORPE, of Copley Dye Works,
Halifax, in the County of York, Dyers, and WALTER DARGUE, of Copley, aforesaid,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to a new construction and arrangement of machine or
apparatus for dyeing hanks of yarn or slubbings.
We employ any suitable shape of vessel for containing the dye or other liquor
and upon suitable framework we mount a series of rollers caused to revolve by
worms and wheels or other suitable means. These rollers carry endless chains
connected together by cross bars or laths. The hanks to be dyed are slung over
the chains and cross bars the end of each cross bar being turned up to prevent the
hanks working off.
Preferably the laths are convex or concave in cross section. After the hanks
have been made to revolve in the liquor in one direction they are by an arrange-
ment of clutches made to rotate backwards in the opposite direction.
Preferably in commencing to use the machine it is made to rotate quickly. After
a period, it revolves slower and if required again at a slower speed, the object of
the decreased speeds being to allow the hanks to remain a longer time in the
liquor. The rollers and hanks are raised bodily out of the cistern for the purpose
of removing the dyed hanks and re-charging again with undyed hanks. The
machine herein described will either dye hanks or slubbing or size them or wash
them.

page_text: 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 a new or improved apparatus for dyeing, sizing and
washing hanks of yarn and slubbing. The object of our invention is to construct
and arrange machinery or apparatus for revolving or traversing hanks of yarn or
slubbing through the dyeing, sizing or washing cistern, and we further employ
an endless chain of links secured together by crossbars or horizontal laths. These
endless chains or network are passed over the upper hank carrying rollers and the
hanks to be dyed are slung over the chains and crossbars the end of each cross-
bar or lath being preferably turned up to prevent the hanks working off. By
the use of this endless chain the bottom hank carrying rollers hitherto employed
will not now be necessary as the endless chain will be sufficiently heavy as to
cause the hanks to sink into the liquor which would not take place without a
bottom roller. In conjunction with the above apparatus we employ machinery
or apparatus for expediting the discharging of the hank carrying rollers and the
refilling of same when the operation of dyeing, sizing or washing is completed."
To the aforesaid purpose our invention consists in the novel and peculiar arrange-
ment of parts as hereinafter fully described. In the accompanying drawings
illustrating our invention:-

Referring to the drawings 1 represents the dye cistern or vessel (or it may he
the sizing or washing cistern): 2 the framework built up on the near side and
left hand end of the cistern for carrying the motor mechanism; 3 the main driving
shaft journalled in bearings in the bracket 4 and driven by strap passing around
the pulley 5; 6 is a shaft arranged at right angles to the main driving shaft
and journalled in bearings in the bracket 4, said shaft 6 having two bevil gears 7
and 8 mounted loosely thereon with which meshes a bevil gear 9 fast on the
shaft 3. Intermediate of the gears 7 and 8 and secured rotatively to the shaft 6
by a key is a double clutch 10 which when slided to right or to left by fork 11
which is attached to a rod 12 as shewn is adapted to engage with one or other of
opposing clutches on the faces of the bevil gears 7 or 8 and thus give motion to

page_text: the shaft
either in one direction or the other as is required. On the end of
shaft 6 is a pinion 13 gearing with a spur wheel 14 on a stud shaft 15 secured
in a bracket 16 bolted to the framework 2, a pinion 17 on said stud shaft gearing
with a spur wheel 18 fast on a worm shaft 19 extending the whole length of the
machine and having right and left hand worms 20 secured alternately thereto
and communicating motion through the shaft 6 to said shaft 19. In mesh with
the worms 20 are worm wheels 21 journalled in brackets 22 bolted to the top of
the framework 2, the inner ends of the studs on which said wheels are secured
terminating in square sided sockets 23 (see Fig. 3 and 9) in which are adapted
to register, when in position, the square ends 24 of the hank carrying rollers 25
which are thus engaged by the sockets and rotate therewith. The hank carrying
rollers are placed loosely in open bearings in brackets 26 secured to the two side
lifter rails 27, which rest at each end in pockets 28 (Fig. 7 and 8) secured to the
top longitudinal edges of the cistern or vessel 1. To the lifter rails are secured
brackets 29 291 whereto are hinged at 30, 30¹, cross or transverse bars 31 carrying
grooved pulleys 32 arranged one near each side of the cistern. The brackets 29¹
are continued to a higher level than the brackets 29 and between the upper ends
thereof are centred nuts 33 through which when rotated by hand wheel 35 the right
and left handed screwed ends of a shaft 34 work and cause the brackets 29, 291 to
move on their centres 30, 30¹, outwardly from the vertical or from the angular to the
vertical as illustrated in Fig. 10, the movement outwardly to the position shewn
in full line in Fig. 10 carrying the lifter rails 27 and the brackets 26 clear of the
two opposite ends of the hank carrying rollers, so that the hanks can be easily and
expeditiously removed from same and a fresh supply placed thereon, this being
done when the lifter rails and parts connected therewith have been traversed
away from the cistern 1. When the rollers have been recharged with hanks,
the brackets 26 and lifter rails 27 are brought back again to the normal position
shewn in dotted line in Fig. 10 and passing under the ends of the hank carrying
rollers the latter by reason of the inclined surfaces at each side of the brackets are
caused to fall into their respective bearings. The hank rollers 25 carry endless
chains of transverse bars or laths 36 of-half round section which are connected to
each other at each end and in the centre of the bars by links 37 passing through
openings in other links 38 to which the bars or laths are rivetted (see Fig. 6).
These endless chains of cross bars are turned or curved upwardly at the ends to
prevent the hanks slipping off and are approximately the length of the longest
hank treated in the class of machine to which this invention refers and they are
collapsible to any extent to suit the various sizes of hanks which may require
treatment in the machine the weight of the chains serving to keep the banks in
a thoroughly distended state. The rollers may be hexagonal as in Fig. 4 or round
as shewn in the other figures, the latter being preferred. In either case small
studs 39 may be secured to the periphery of each roller, to take into the links 37
so that the chains will be traversed around the rollers positively.
When charging the rollers 25 with hanks they are placed each in separate
hinged frames 40 carried on a carriage 41 adapted to travel transversely of the
cistern, so that it can be run from one cistern to another alongside it and thus
serve for any number of cisterns (if required) arranged side by side. The middle
of the rollers 25 rest on the upper ends of the said frames and the endless chains
descend into the openings 42 as shewn at Fig. 12, so that the endless
chains of bars are unobstructed on either side of the frames and admit of the hanks
being passed on or drawn off by the workman without difficulty, there being the
space left in the middle, where the frames support them, to divide the hanks on
one side from those on the other, whereby when dyed and brought back again,
the endless chains of bars will pass into the openings 42 without carrying the
adiacent hanks into same. After charging endless chains, whose collapsed
condition in the openings 42 admits of the hanks being passed over same without
stretching or extending them, the lifter rails 27 and brackets 26 are brought to
the vertical position, as before explained, and the rollers 25 journalled in the

page_text: bearings in said brackets, whereupon the whole is then raised by means of a
double system of wire ropes attached to winding and unwinding barrels 43 and
passing around pulleys 44 on overhead travelling carriages 45 (Fig. 11) then
under the pulleys 32 and over other pulleys 46 on said carriages 45 and secured
at 47 to a bracket 47¹. When raised to a height to clear the frames 40, the whole
is traversed forward over the machine by a wire rope 48 attached at one end to a
barrel 49 and at the opposite end to the near carriage, both carriages being con-
nected together by a rod or link 50. The lifter rails and parts are traversed
backward or in a reverse direction away from the machine by a second wire rope 51
connected at one end to the barrel 49 and passed around a pulley 52 and attached
to the rear carriage as shewn at Fig. 11.
On arriving in position over the cistern, the hanks, carrying rollers, and parts
are lowered until the lifter rails bed themselves in the pockets 28, the square
ends 24 of the hank carrying rollers at the same time entering the
square sockets 23 on the ends of the studs carrying the worm wheels
whose motion is timed to bring the open sides of all said sockets
uppermost so that all are in position to receive the square ends 24 of the hank
carrying rollers. Motion is now given to the machine by sliding the clutch
box 10 into gear with one or other of the bevil wheels 7 or 8, the right and left
hand worms giving motion in opposite directions to the hank carrying rollers
which traverse the endless chains and hanks through the liquor in the cistern 1.
To reverse the motions of the parts the clutch box 10 is moved out of gear with
the bevil wheel it has been engaged with into gear with the second bevil wheel
as will be understood.
The motion for driving the barrels 43 and 49 is derived from the shaft 6 through
the medium of a bevil gear 53 on the end of said shaft meshing with a bevil
wheel 54 on a shaft 55 journalled in bearings 56 on the end frame of the machine.
Mounted loosely on said shaft 55 are two worms 57 one right hand and the other
left hand into which mesh toothed wheels 58 on the axes of the barrels 43. A
third worm 59 is also mounted loosely on the shaft 55, which gears with a toothed
wheel 60 on the axis of the barrel 49.
61 and 62 are levers centred at 63 to which are connected rods 64, 65, attached
at their opposite ends to bosses 66 and 67 respectively secured to slide rods 68
and 69 supported in brackets at each end. To the slide rods 68 are secured two
clutch forks 70, 70 engaging with clutches 71, 71, which are secured rotatively to
the shaft 55 but can be slided thereon into and out of gear with opposing
clutches 72, 72 forming part of the worms 57 which can thus be set in motion or
stopped by moving the lever 61 to the left or right. When said lever is moved
to the left the clutches are placed in gear and motion is thus given to the barrels 43
for the purpose of raising or lowering the lifter rails and parts. By moving the
lever 62 to the left the slide rod 69 is slided endwise, a clutch fork 73 thereon
sliding a hollow friction clutch 74 into engagement with a friction cone 75
whereby the worm 59 is driven and gives motion to the barrel 49, which traverses
the carriages 45 backwards and forwards on the girder 76 therefore carrying the
lifter rails and parts over or away from the machine, the requisite direction of
motion of the parts for the aforesaid purposes being given by the direction of
motion of the shaft 6.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that we make
no general claim to the use of rollers and endless carriers on hank dyeing machines
but what we claim is:-
