Improvements in and relating to Yarn Dyeing Machines.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 :-
My invention relates to a device adapted for use in dyeing yarn and it consists in
the novel construction and combination of the several elements and parts herein-
after particularly described.
Like numerals indicate like parts in the various figures.
Figure 1 is a top plan of my invention.
Figure 2 is a side elevation of the same.
Figure 3 is a view of my invention, partly in elevation and partly in section, as
seen on line x, x of Figure 5.
Figure 4 is a view of my invention, partly in elevation and partly in section, as
seen on line y, y, of Figure 3.
Figure 5 is a front elevation of one end of my improved machine.
Figures 6 and 7 are, respectively, front and side elevations of the rock shaft and
its connected parts drawn to an enlarged scale.
Figures 8, 9 10 and 11 are detail views.
Figure 12 is an enlarged top plan to illustrate the cams and their means of
rotation, together with the reciprocating bars with the yarn sticks thereon.
Figure 13 is a side elevation of the same.
Figures 14 and 15 show, respectively, the relative positions of the cams and the
reciprocating bars moved thereby, at the two extremes of their travel.
In the accompanying drawings, 1 represents the bed or platform of the machine,
rectangular in form, upon which are erected four standards 2, preferably metallic,
having longitudinal grooves and shaped in cross section, as shown in Figure 1.
A tank or vat 3, preferably of wood is placed upon the platform and holds
the dyeing liquor. On each side of the tank 3, near the bottom and ends thereof,
are brackets 4, 4, having suitable bearings, and at or near the centre of the tank,
near the bottom thereof, is the bearing 5, while on rear or right hand end of the
tank 3, as seen in Figure 2, near its bottom, are the brackets or bearings 6 and on
the opposite or front end of the tank, near its bottom, are the upwardly curved
brackets 7, 7.
Rails 8 are arranged on two opposite sides of the tank (but not connected
therewith) to form a track. The rails extend from end to end of the machine
and enter loosely into the grooves or channels of the standards 2, as seen in
Figures 1 and 2. Said rails 8 have near their ends, respectively, a tubular
portion or support 9, whose bore is screw-threaded.
On each of the four bracket bearings 4, 4, is mounted a long screw-threaded
rod 10, (see Figures 2 and 4) which also passes through and is supported by the
tubular portion or support 9 of the rails 8, and engages by said screw-threads
with said tubular portions of the rails. The rails 8 are thus supported upon
said screw-threaded rods and are movable vertically upon said rods, when the

page_text: latter are rotated. The grooves of the standards 2, into which the ends of
said rails enter loosely, keep the rails 8 parallel with each other and direct
their vertical movement. Each rod 10 has at its lower end a bevel gear 11.
On each side of the tank 3, is a horizontal shaft 12, mounted in the bearings 4, 4
and 5, and provided with the large bevel gear 13 at its front end, and with
the small bevel gear 14 at its rear end and with the bevel gears 15 and 16, near
the ends. The bevel gears 15 and 16 engage, respectively with the bevel gears 11
and 11 at the lower end of the rods 10 and 10, respectively. On the front end
of the tank 3 is mounted in the brackets 7, 7, thercof a shaft 17, on the ends
of which are the bevel gears 18 and 19, the latter engaging with the bevel
gear 20 on the front end of the shaft 21. On the rear end of the tank 3, is
mounted in the brackets 6 thereof, a shaft 22, ou the ends of which are the
bevel gears 23, engaging, respectively, with the bevel gears on the rear end of
the shafts 12 and 21, respectively.
A carriage or frame composed of the side bars 24 and 25 and the cross bars 26
and 27 (bolted to the bars 24 and 25, as shown at 28 Figure 1), travels back
and forth by its trucks or flanged wheels 29 upon the rails or track 8, 8. The
wheels 29 are mounted upon journals 30 extending downward from the side bars 24
and 25.
On each side bar 24, 25, is mounted an arm 31, pivotally connected at 32
upon an extension 33 of said bar. The arm 31 has a central enlargement in
which is a slot (see Figure 2). A bracket 34 extends from the side bar 24, on
each side and has a tubular socket or chamber, in which is a spiral spring 35,
whose outer end bears against the top of the arm 31, at its free end.
A lever arm 36 is pivotally mounted at 37, to the tank 3 on each of its
two sides and has at its end a pin or stud 38 which enters the slot in the
arm 31.
In a standard 39 (Figure 5) is mounted a vertical shaft, 40, which is provided
with a gear 41, having a concave periphery. At the upper end of the shaft 40
is a bevel gear 42. The shaft 40 is also mounted in the bearing 43. A cross
shaft 44 is mounted in the standards 2 and has at or near its centre a bevel
gear 45
which engages with the bevel gear 42 of the shaft 40. At the ends of the cross
shaft 44 are crank arms 46 and from each crank arm 46 extends a link or
rod 47, pivotally connected at one end with the crank arm 46, and at the
other end with one of the lever arms 36, near the centre thereof see Figures 2
and 3.
Top yarn sticks 48 are detachably mounted on supports 49 on the tops of the
side bars 24, 25, and extend across the frame or carriage.
At the ends of the side bara 24, 25, are cross shafts 50 and 51, extending from
side to side. The cross shaft 50 has at its ends the bevel gears 52 and 53 and the
cross shaft 51 has at one end (Figure 1) the bevel gear 54. On the further side
of the frame on the side bar there, brackets 55, 55, are fastened, in which is mounted
the shaft 56. The shaft 56 has at its ends the bevel gears 57 and 58, which
engage, respectively, with the bevel gears 52 and 54, of the cross shafts 50 and 51.
The cross shafts 50 and 51 are cam shafts.
The cross shaft 50 has fastened thereon the four eccentric cams 59, 59, 59, 59.
The cross shaft 51, has fastened thereon the four eccentric cams 60, 60, 60, 60.
The cams 59, 59, have their inner faces in contact (Figure 5), and have their
outer faces extended to form flanges 61.
The cams 60, 60, also have their inner faces in contact and are provided
with flanges on their outer edges, as indicated by dotted lines in Figures 1, 2
and 3.
On the outer face of each cam 60, 60, is made a channel 62 of the peculiar
shape, illustrated in Figures 9, 10, 12 and 13. By the latter figure, as is shown
by the arrows therein, it is seen that the cams 60, 60, at the opposite ends of the
machine, turn in directions opposite each other so that while the bar 63 is moving
in one direction, the bar 64 (Figure 12) is moving in the opposite direction. In

page_text: Figures 14 and 15 I show by means of the dotted lines and arrows the travel of
the yarn sticks 70.
Reciprocating bars 63, 63, 64, 64, having their eals curved and shaped as seen
in Figures 2, 3, 9 and 10, rest by said ends upon the tops of the cams 50, 60, 59, 60,
respectively, the thickness of said bars 63, 64, together being such as to cause
them to fill the space between the flanges 61 61 of the cams 59, 60, 59, 60,
respectively, as shown in Figure 5. Near the rear end each reciprocating bar 63
bas a projection 65, which carries on a stud 66 upon its enl a roller 67, which
enters and is rotatable on the channel or groove 62 of the can 60. A similar
projection 68, extends from the reciprocating bar 64 near the eat thereof and has
a similar roller, mounted on a stud and engageable with the channel or groove in
the cam 60. The reciprocating bars each have a series of supports 69 on which
are detachably mounted yarn sticks 70, arranged as shown in Figures 1 and 2. In
Figure 1, it is seen that the yarn sticks extend alternately between the reciprocating
bars 63, 63 and the reciprocating bars 64, 64.
On the rear cross bar 26, of the carriage or frame is mounted in suitable
bearings a shaft 71, having a crank handle 72 at one end and a bevel gear 73 at
its opposite end. It also has the bevel gears 74, 75. On the front cross-bar 27
of said carriage or frame is mounted a shaft 76, having at its ends the bevel
gears 77 and 78, and also the bevel gear 79 see Figure 1. In a longitudinal
groove of the side bar 24, is mounted a shaft 80 Figure 2 having at its ends the
bevel gears 81 and 82. The bevel gear 81 of the shaft 80 engages with the bevel
gear 75 of the cross shaft 71 and the bevel gear 82 of the shaft 30 engages with
the bevel gear 77 of the cross shaft 76.
From the cross bars 26 and 27 parallel hangers 83, 83, 83, 83, extend downward,
which are connected at their bottoms from end to end of the machine by the bars 84
and crosswise of the machine by the bars 85.
In the parallel hangers 83, 83, 83, 83, are bars 86, 86, movable therein and in
said hars 86, 86, bottom yarn sticks 87 are detachably mounted (Figures 3 and 4).
Screw-threaded rods 88, 88, 88, 88, extend down into said hangers and pass through
screw-threaded bores in the bars 86, 86. The rods 88, 88, 88, 88, have at their
upper ends, respectively, the bevel gears 89, 90, 91, 92, which engage, respectively,
with the bevel gears 74, 73, 79, 78, of the cross shafts 71, 76.
On one side of the machine is a vibrating rock shaft 93 Figure 2 mounted loosely
by a collar 94, on the shaft 17. The shaft 17 has the bevel gear 18, which engages
with a bevel gear 96, on the rock shaft 93. Said shaft 93, has a longitudinal
groove 97, shown in full lines in Figure 7 and in dotted lines in Figure 8. This
groove 97 extends nearly to the upper end of the rock shaft 93.
The rock shaft 93, is also supported in the tubular bearing 98, which is provided
with a dove-tailed plate 99. This plate 99, is movable upon the rail 8, between
ways 100. The tubular support 98, has a central tubular socket 101 (Figure 8).
A sleeve or tube 95, is loosely mounted on the rock shaft 93 and fits loosely
within the socket 101 of the tubular support 98. The sleeve 95 has a flange 102 at
its top, which is provided with radially arranged teeth 103. A spiral spring 104
surrounds the sleeve 95 and has its bearings against the underside of the flange 102,
and the upper end of the tubular support 98.
A sleeve or tube 105, has at its bottom the bevel gear 106, and is loosely
mounted on a tube (see Figure 8), which is itself mounted on the rock shaft 93.
Said bevel gear 103 has the radially arranged teeth 107. The teeth 107 of the
bevel gear 106 are engageable with the teeth 103 of the sleeve 95, as shown in
Figures 6 and 7. A collar 108 by a set screw 109 is fastened to said interior
tube on the rock shaft 93. A spline on the interior or bore of the sleeve 95 enters
the longitudinal groove 97 of the rock shaft 93, as seen in Figure 8.
On the side bar 24, is a yoke 110, bolted at 111 thereto, and through this yoke
a stud pin 112 (Figures 6 and 7) extends from the sleeve 105. In this yoke 110
is also mounted one end of the cam shaft 50, having the bevel gear 53, engageable
with the bevel gear 106 of the sleeve 105.

page_text: On the shaft 17, (Figure 11) is the worm gear 125 and the sliding cone
clutches 113, 114, movable on said shaft by a spline connection. The bevel
gear 115, on the shaft 17, has a conical socket adapted to receive the clutch 113,
and the bevel gear 116 on the shaft 17 has a conical socket adapted to receive the
clutch 114. Each clutch 113, 114, is circumferentially channelled. Levers 117, 118,
are pivoted at 119 and 120, respectively, to the tank 3 and have stud pins which
enter the circumferential groove of the adjacent clutch. The levers 117, 118, are
connected by the rod 121, pivotally mounted at its ends thereon. The bevel
gears 115, and 116, are loosely mounted on the shaft 17.
The extension rails 122 Figure 2 are pivotally mounted at the upper ends of the
standards 2 and may be supported by braces or otherwise.
The skeins of farn are shown at 123 Figures 3 and 4 passing over the yarn
sticks.
Having described the several parts of my improved machine, I will now
explain its operation, beginning with the machine in the position, illustrated in
Figures 1, 2, 3, and 4.
The tank or vat 3, is partially filled with the dye liquor, as indicated by broken
horizontal lines in Figures 3 and 4.
The yarn skeins pass over the yarn sticks 48, 70, and 87, their lower portions
being submerged in the dye liquor.
The yarn skeins 123, are drawn to a proper tension between the yarn sticks 48
and 70 respectively, by turning by hand the crank handle 72, of the shaft 71. The
bevel gears 75, 74 and 73 of said shaft 71, respectively, turn the bevel gears 81, 89,
and 90, of the shaft 80 and of two of the rods 88, 88. The shaft 80 so turned by
the bevel gear 81, turns by its other bevel gear 83, the shaft 76, with its bevel
gears 78 and 79. The bevel gears 78 and 79 of the shaft 76, turn the other two
vertical shafts 88, 88, by means of their bevel gears 91, 92, respectively. The
turning of the vertical rods 88, 88, 88, and 88, so caused, results by reason of
their screw-threaded connection with the bars 86 and 86 in the vertical move-
ment up or down, as may be desired, of said bars 86, and 86, in the hangers 83, 83,
83, 83, and the yarn skeins are thus drawn to the proper tension by the bottom
yarn sticks mounted in and movable vertically by said bars 86 and 86. The shafts,
bars and hangers, which are submerged in the dye liquor, should be made of bronze,
or of a metal not liable to be corroded or affected by the liquid dye.
The yarn skeins 123, so mounted on the yarn sticks 48, 70 and 87, require both
a horizontal reciprocating movement and also a progressive intermittent vertical
movement or feed motion.
The horizontal reciprocating movement is given as follows: Power is applied
from a steam engine or prime motor to the shaft 17 by a pulley thereon (not shown),
turned by a belt. The shaft 17, by its worm gear 125, turns the wheel 41 of the
shaft 40 and the bevel gear 42, attached to the shaft 40. The bevel gear 42 turns
the bevel gear 45 of the shaft 44 and with it the cranks 46 and 46 on said shaft.
The cranks 46, 46, give a reciprocating movement to the links or rods 47, 47, and
these communicate an oscillating movement to the levers 36, 36, mounted on the
tank (Figure 2). The levers 36, 36, by their stud pins 38, 38, at the upper end
thereof, engage in the slots of the lever arms 31 31. The lever arms 31, 31, being
pivotally fastened to the side bars 24, 25, of the travelling carriage or frame, cause,
by their said connection with the oscillating levers 36, 36, the carriage or frame to
move back and forth, travelling upon the trucks, or wheels 29, upon the rails or
track 8, 8.
As all the yarn sticks are carried by this frame, the yarn skeins upon said
sticks are moved regularly back and forth in a horizontal direction in the tank
and their submerged portions are thus perfectly subjected to the dye liquor in said
tank.
As the top of each lever 36, in oscillating, as above described, necessarily moves
in an arc of a circle, the lever arm 31, which engages by its slot with the stud pin 38
of the lever 36, rises and falls to maintain said engagement and is kept in proper

page_text: relative position and contact with the lever 36 by means of the spiral spring 35,
which, mounted in the socket of the bracket 34, has its free end always in forcible
contact with the end of the lever arm 36.
The vertical feed motion is given to the yarn skeins 123 by the following means..
The shaft 17, rotated by power as already stated, turns the bevel gears 18 and 18.
thereon. The bevel gears 18, 18, turn, respectively, the bevel gears 96 and 96 of
the vibrating or rock shafts 93 and 93. Said shafts 93, 93, so turned, cause the
tubes or sleeves 95, 105, thereou to turn with them, being engaged therewith by
the spline connection of the sleeve 95 with the longitudinal groove 97, of the rock
shaft 93. The teeth 103 of the sleeve 95, engage with the teeth 107, of the
sleeve 105, and compel the sleeve 105, to turn with the shaft 93, and the sleeve 95..
This turning of the sleeve causes the bevel gear 106, on said sleeve to turn also,
which gear 106, engaging with the bevel gear 53, turns the cam shaft. 50. The
cams 59, 59, are arranged in pairs, as seen in Figures 1 and 5, and are simply lifting
cams. The cam shaft 50 has a bevel gear 52, which turns the shaft 56 by the bevel
gear 57 and the bevel gear 58 on said shaft 56 turns the bevel gear 54 of the cam
shaft 51. The cams 60, 60, are arranged in pairs on the cam shaft 51.
The reciprocating bars 63, 63, by their curved ends rest upon the top of the
cams 59 and 60 on the peripheries thereof, respectively, and the reciprocating
bars 64, 64, by their curved ends rest upon the top of the companion cams 59 and 60-
on the peripheries thereof. The roller 67, upon the stul 66, of the projection 65,
of each reciprocating bar 63, is rotatable in the channel 62 in the face of the
underlying cam 60, as already described.
The rotation of the cam shafts 50 and 51 causes the rotation of the cams 59 and 60
thereon. The reciprocating bars 63, 64, resting on the peripheries of said cams,
respectively, regularly rise and fall, as said cams revolve. At the same time, the
rotation of the cams 60, 60, by means of the channel in each of them and the
rollers 67, of the projections 65, 68, of said reciprocating bars, give a regular
horizontal movement to said bars, alternately, back and forth. These two.
movements imparted to the reciprocating bars give a regularly intermittent feed
motion to the yarn skeins, which I will now describe. When the yarn sticks 48.
and 70 are in the position seen in Figure 10, the top of the yarn skein lies straight.
across the tops of said yarn sticks. The movement of the yarn sticks 70, is indicated'
in a dotted curve in Figures 9 and 10. When the top edge of the yarn stick 70-
lins reached the point indicated at the lower end of said curve, it is lifted by said
cam action and comes up alongside of the yarn stick 48 and lifts the yarn skein
bodily off said yarn stick and carries the top of said skein to the position indicated.
by the top of said curved dotted line in Figures 9 and 10. This is the position
more fully illustrated in Figure 3. Then as the yarn sticks 70 descend that part.
of the skein indicated by 124 in Figure 3, rests upon the top of the yarn stick 48 and
so the skeins are progressively lifted over and moved upon the yarn sticks 48.
But inasmuch as the travelling carriage or frame is the meanwhile moving back.
and forth horizontally upon the rails, as herein before specified, it is evident that
the rock shaft 93, 93, must be adapted to oscillate or vibrate to allow such move-
ment and this vibration of the shafts 93, is possible by the following devices.
The vibrating shaft 93, has at its bottom a collar 94, loosely mounted upon the
shaft 17, and is also supported in a tubular bearing 98, which slides in ways 100,
upon the rail 8, 8. A stud 112 extends from the sleeve 105, and passes through a.
hole in the yoke 110 (Figures 6 and 7).
When the yarn has been sufficiently subjected to the dye liquid it is removed
from the tank 3. This is accomplished by the following instrumentalities. By
the handle 117, the coue clutch 113 (Figure 11) is thrown into engagement with.
the adjacent bevel gear 115, on the shaft 17. Said bevel gear engages its companion
bevel gear 13 and turns thereby the horizontal shaft on that side near the bottom
of the tank. This shaft has bevel gears, which, engaging with the bevel gears of
the vertical screw-threaded rods, turn them also, while the bevel gear at the rear end
of said horizontal shaft by its engagement with the bevel gear of the rear cross-shaft.

page_text: turns that shaft, and said shaft by its bevel gear engaging with the bevel gear
on the end of the next horizontal shaft turns said horizontal shaft, while the bevel
gears on said last mentioned horizontal shaft by their engagement with the bevel
gears on the bottom of the other two vertical screw-threaded rods turns said rods.
Thus all four of said vertical screw-threaded rods are turned at the same time, in
the same direction, and by reason of their engagement, respectively, in the screw-
threaded bores of the tubular supports 9, of the rails 8, the continued rotation of
said vertical rods, causes the rails to rise and move upward with their ends in and
guided by the groove or channels in the standards 2, and the rails 8, thus raised,
lift with them the travelling carriage or frame, which by its trucks 29, rests on said
rails, and as the carriage or frame carries or supports the yarn sticks and the yarn
thereon, the whole frame with its load of yarn is lifted out of the tank 3. This
lifting movement continues until the rails 8, are raised to the level of the
extension tracks 122 and the carriage can then be rolled off by its truck wheels
upon the extension track 122 to a position sufficiently remote from the tank to
permit the unloading of the yarn from the yarn sticks, and away from the steam
and vapour of the dye stuffs in the tank.
But during all the time of this lifting movement, it is still necessary to continue
the intermittent feed movement of the skeins, otherwise the lower portion of the
yarn skeins would be longer submerged in the dye liquor and so absorb more of the
dye-stuff and the skein would be unevenly coloured thereby. For this reason,
the sleeves 95 and 15 are provided, which though turning with the rock-shafts 93, 93,.
are movable longitudinally on said shafts, being engaged with each other by the
teeth 103 and 107 and also by the spline of the sleeve 95, entering into the
groove 97, of the rock shaft 93. The upward limit of such longitudinal movement
of the sleeve 95 is indicated in Figure 8, where it is seen that the top of the
spline of said sleeve serves as a stop when it comes in contact with the end of
the groove 97. The upward movement of the rail 8, however, still continuing,
lifts the sleeve 105 off the top of the rock shaft 93 and draws its teeth 107 out
of engagement with the teeth 103 of the sleeve 95, as said sleeve 105 by its
stud 112 passing through the aperture in the yoke 110 is attached to the side bar 24
of the carriage.
Another lot of yarn skeins are loaded on the yarn sticks while the carriage is out
on the extension tracks away from the tank. When loaded, the carriage is run off
from the extension tracks onto the rails 8, which have in the meanwhile remained
in their elevated position upon the tops of the vertical screw-threaded ruds, and
when the sleeve 105 on each side has been brought into position over the
sleeve 93 on each side, the carriage is lowered to the position shown in Figure 2
again. This lowering movement is caused by throwing the other cone clutch into
connection with its adjacent bevel gear (Figure 11) and the two horizontal shafts
and rear cross-shafts are rotated in the directions opposite to those required for the
lifting movement above described and so the vertical screw-threaded rods by their
engagement with the screw-threaded tubular supports 9, of the rails 8, cause the
carriage and its load to descend to the position shown in Figure 2.
But it is necessary that during the whole time of this lowering movement that.
the yarn skeins should have the progressive feed motion described. This is
accomplished as follows: As the carriage descends, the sleeve 105, descends to
the sleeve 95, and as the latter is turning, the two sleeves 95 and 105 at once
engage by their teeth 103 and 107, coming from the position shown in Figure 8.
to the position shown in Figure 6. As the weight of the sleeve 105 falls upon
the sleeve 95, the spiral springs 104 are compressed. The vertical feed motion
of the skeins thus begins before the skeins come into contact with the dye liquor.
The horizontal reciprocation of the carriage, and yarn sticks does not however take
place until the rails have reached their first position and the lever arm 31 of the
carriage is again engaged by its slot with the stud pin of the lever 36, as before.
The uniformity and regularity of the intermittent feed motion, not only gives an
equal exposure of all parts of the skein to the dye liquor, but also an equal air

page_text: exposure to all parts of the skein during the process, for dyeing and for the
proper oxidation of the dye stuff thereon. In this mauner absolute uniformity
of result is obtained. All the time the yara skeins are intermittently and progres-
sively moved, as aforesaid, the carriage (when the parts are in the position shown in
Figure 2) moves back and forth, carrying the skeins to and fro in the tank and
liquor, thus imitating the hand motion used by dyers in colouring yarn by hand
processes and for the same purpose.
The dyeing liquor can be kept continually at the boiling point, as both the
horizontal and vertical movements of the yarn skeins are accomplished auto-
matically; hence it is not necessary to shut off the steam, as it would be, if the
yarn sticks were turned by hand or the yarn skeins moved to and fro in the liquor
by hand, as heretofore.
My improved machine for dyeing yarn can easily be operated by one man,
without assistance, and can be loaded with yarn, or unloaded, in easy reach from
the floor, while the frame or carriage is upon the extension tracks and out at one
side of the tank, and so the workman is not exposed to the heat and fumes of the
dye stuffs.
I have provided extension tracks on both ends of the machines and so two
carriages may be used, and one loaded or unloaded, while the other is in use over
the tank.
Another advantage possible with the use of my device is that the dyeing liquor
may be strengthened or "stuffed," while the yarn is entirely free from the tank and
raised therefrom by the devices described, and the frame or carriage can be there-
after lowered again into the former position. Thus the danger of streaking the
yarn, experienced in the hand process whenever the strength of the liquor is
increased, is entirely avoided.
It will be observed that this bodily lifting of the skein from the yarn sticks 48
by the yarn sticks 70, followed by the bodily lowering of said skein, as described,
dispenses with the frictional drag of the yarn upon the yarn sticks, as hereto-
fore common, and so prevents any wear or waste of the yarn during the dyeing
operation.
These movements of the yarn sticks may be accomplished by other mechanical
means than those described, but such movements of the yarn sticks, however
derived from mechanism, are within the scope of my invention.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. In combination with a dye vat, the fixed upper and lower bars having yarn
sticks detachably mounted therein, respectively, from side to side, two cam shafts
mounted transversely beneath said upper bars near the ends thereof, the recipro-
