Certain New and Useful Improvements in Dyeing Apparatus.
I, SYDNEY PITT of Sutton in the County of Surrey, Gentleman (a communication to
me from abroad by Alexander Smith and Sons Carpet Company of Yonkers in the State
of New York, United States of America) 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:-
Previous to the present invention it has been customary to hang the hanks of yarn
which are to be dyed upon poles and to lower them into the dye vat until the poles rest
upon the opposite edges of the vat; and after the portions of the hanks of yarn which
are hanging in the dye liquor become wetted by it, it has been customary to shift the
hanks upon the poles by hand so that the portions of said hanks which have been wet.
with the dye liquor are drawn from the dye vat, and the portions which rested upon
the poles are let down into the dye liquor. In order that the yarn may be dyed
equally, this shifting of the hanks has to be repeated a number of times, and con-
sequently a large amount of labor has been heretofore required for this purpose. In
addition to this hand method, various machines have been devised to shift the hanks
or skeins of yarn in the dye liquor, and so far as I know these machines operate upon
the following plans-In some of them the skeins of yarn are hung upon rollers, or
upon reels which are revolved so as to cause the skeins to move like endless belts
running on pulleys. In others the skeins of yarn are held on revolving creels or
frames which revolve in the dye liquor. In others again, the skeins are pulled
laterally over the poles but without the yarn being raised from the poles. But none
of these machines so far as I know raise the skeins or hanks from the poles and then
lower them as is done by the hand method above referred to.
The object of this invention is to operate upon the hanks, or skeins or similar articles
while in the dye liquor, by machinery, in a manner similar to the manipulation of the
skeins or hanks by hand, so as to attain the good effects in the dyeing of yarn
which are incident to the hand manipulation of the skeins or hanks, and at the same.
time reduce greatly the labor required. This invention consists of certain mechanism
or combinations of mechanical devices by means of which the hanks of yarn, or other
similar articles hanging upon poles, may be shifted in the dye liquor without hand
labor and may if desired be trailed through the dye liquor. These combinations are
set forth in detail in the claims at the close of this Specification; and, when the entire
invention is used the banks of yarn hanging upon any one pole are not only shifted
in the dye liquor, but each pole of a series upon which hanks of yarn are hung in a
dye vat has the hanks upon it shifted in succession, so that all the hanks of yarn which
are being dyed at any one time in the same dye vat are shifted in the dye liquor the
requisite number of times required to complete the dyeing of the yarn. In order that
the invention may be fully understood I have represented in the accompanying
drawings and will proceed to describe the form of dyeing apparatus which it is
preferred to use and which embodies all parts of the invention in the best form at
present known to me.

portions removed between the broken lines (at x x) of the said figure.

Figure 9 represents a side view of the inner side of the end of one of the raising
arms and its appurtenances; and

Figure 11 represents a side view of the lifting cam and its appurtenances.
Figure 12 represents a side view of one of the shifting rod cams and some of the
connections with the shifting rod.
Figure 13 represents a side view of a part of the apparatus showing an automatic
stop mechanism which I prefer to use as hereinafter described.
The dye vat A of the said apparatus is of rectangular form and is preferably deep
enough to permit the hanks of yarn to hang in it from poles without touching the
bottom. Its width should be adapted to the number of hanks of yarn which are to be
placed upon the poles, a convenient width being about 3 feet. The length of this dye
vat should be adapted to the number of poles which are to be used for holding the
hanks of yarn, and when the machinery is constructed in the form represented in the
drawings, it is preferred that the distance between two successive poles should be about
seven inches. The dye vat sets within a frame B, which sustains the various
moving parts of the apparatus. The series of poles C, from which the banks of
yarn are suspended, extend transversely across the dye vat; and when the apparatus
is in use these poles are sustained by a pole carriage D, which is preferably made
movable lengthwise of the main frame by being fitted with wheels d, that run
upon longitudinal rails b, which are connected with the main frame B, so that
the pole carriage with the poles C, and the hanks of yarn hanging thereon, may
be moved to and fro longitudinally of the vat for the purpose of placing each
pole in succession in the proper position to have the banks of yarn upon it
shifted. In order that the poles with the banks of yarn may be readily applied
to and removed from the dye vat, it is preferred to connect the poles with a
movable frame D¹, which may be raised bodily from the dye vat and may be
replaced by another pole frame of the same character having a new set of hanks
applied to its poles. The ends c of the poles are preferably notched at their under
sides to rest upon the sides of the pole frame, and those sides d2 also are preferably
notched at the requisite distances to hold the poles in their proper relative positions.
Each pole is constructed in such manner as to permit it to be traversed longitudinally
by a shifting rod; and the construction of pole which it is preferred to employ for this
purpose is a pole of gutter form or U section (as represented in the drawings) open at
the top, so that the shifting rod, after being inserted end wise into the cavity of the
pole and into the bights of the hanks of yarn hanging upon the pole, may be raised so
as to lift the hanks of yarn from the pole. If the dye vat be sufficiently narrow, a
single shifting rod may be used to raise the banks of yarn from the pole; but it is
preferred to use two shifting rods E E, which are arranged at opposite sides
of the pole carriage, are inserted endwise into the bights of. the hanks of yarn, are
then raised to lift the said hanks, and are subsequently lowered to lower the said hanks
into the dye liquor, after which the shifting rod is withdrawn endwise from the said
hanks. The mechanism which it is preferred to use to impart these reciprocating
movements to the shifting rods is as follows:-Each shifting rod E, is supported
by an arm F; by means of which it may be raised and lowered; the rod is con-
nected also with a lever G, by means of which it may be inserted endwise into
and withdrawn from the hanks of yarn. As two shifting rods are used in the
mechanism represented in the drawings, the two lifting arms F F, of the two
shifting rods E E, are secured to a common rock shaft G, which is fitted with an
intermediate arm F¹ and this intermediate arm is operated by the lifting cam F2,
through the intervention of a lever f, and a link f³, so that as the said lifting
arm F³, revolves, the shifting rods that are carried by said arms are raised and
lowered, or reciprocated up and down, relatively to the pole carriage. The lifting

page_text: cam F2 is secured to a cam shaft H, which is fitted to turn in suitable bearings
upon the main frame B, and has a revolving motion imparted to it through the
intervention of the cog wheels and pinions a a¹ a² a³ and shafts at a³ by means of
a belt applied to the driving pulley I. The lever G by means of which the
shifting rod is inserted and withdrawn end wise from the hanks of yarn is fitted
to an extension g of the rock shaft G of the lifting arms. The longer arm of
this lever is connected pivotally with the outer end of the shifting rod E; and
the lever is vibrated in horizontal directions for the purpose of inserting and
withdrawing the shifting rod by means of a cam E¹ which I call the shifting cam
and which is secured to the cam shaft H and operates upon the said lever G and
the shifting rod E through the intervention of the lever g' (which swings on the
fulcrum stud 9 Figure 2) the rod g² the elbow lever g³ and a connecting rod g*. The
reciprocation of the shifting rod in a direction end wise of its length for the purpose of
entering into and withdrawing from the skeins or hanks of yarn hanging on the poles,
is an essential feature of the invention, and whenever hereafter the end wise
reciprocating shifting rod is mentioned it is to be understood as one having that
endwise reciprocating movement.
Each endwise reciprocating shifting rod is fitted to slide end wise in the end of the
lifting arm F; and as the two reciprocating shifting rods are inserted from opposite
sides of the dye vat so that their inner ends come together, they are capable of lifting
all the hanks of yarn upon the pole in connection with which they are operating.
When two end wise reciprocating shifting rods are so used it is preferred that the
end of one of the two should be fitted with a pin or dowel 3 Figure 6ª and
that the inner end of the other shifting rod should be socketed to receive the
dowel; and that the end wise motion imparted to the shifting rods by their cams E'
should be sufficient to cause the dowel f2 of one rod to enter the socket of the
other rod so that the inner ends of the two shifting rods are then connected;
because such connection tends to render them stiffer when rais ng the hanks. The
shifting rods may be constructed with advantage of drawn copper tubes as this
material is light and stiff.
When an endwise reciprocating shifting rod is withdrawn from the hanks, it is
desirable that the hanks should be prevented from moving along with the shifting
rod. In order to prevent such movement the lifting arm of a shifting rod is
fitted with a stripper J which is preferably arranged to slide in a guide j¹ (Figures 7, 8,
9, 10) at the outer end of said arm above the shifting rod E. The stripper is
fitted with a spring; which tends to hold it in its outermost position as represented
at Figure 8; and a shoulder e is connected with the outer end of the shifting
rod E to operate upon the outer end of the stripper J and push that stripper
inward as the shifting rod reaches its innermost position, so as to push the hanks
of yarn towards the inside of the dye vat.
In order that each pole C of the series on the pole carriage D may be carried
longitudinally of the dye vat the pole carriage D is moved or fed longitudinally
of the said vat, and the moving or feed mechanism which it is preferred to use
for this purpose is as follows: A rack bar K is secured to the carriage and a
reciprocating feed pawl K' is provided to engage with the teeth of the said rack
bar and move it and the pole carriage forward. The said feed pawl is pivoted to the
upper end of a pawl lever k which is operated by the feed cam K² through the
intervention of a lever (which swings on the fulcrum stud to Figure 2) rod k
counter lever and rod k. The feed pawl K is preferably moved in a forward
direction only by the action of the feed cam K2; and in this case the return
movement of the feed pawl is effected by means of a spring ko.
In order that the pole carriage D may not be retrograded during the backward
movement of the feed pawl a stop pawl is provided to drop in behind the teeth of
the rack bar in succession and prevent such retrograde movement.
In the operation of the said machine it is expedient that the bights of the hanks
of yarn after being raised from the pole should be lowered so as to drop into the
vat between the pole from which they were raised and the next succeeding pole,"

page_text: so that portions of the hanks which previously to the raising hung in the dye
liquor are left hanging upon the pole when the hanks are lowered and that those
portions of the hanks which rested on the poles previous to the raising are dropped
into the dye liquor when the hanks are lowered. Hence the lengths of the teeth
of the rack bar K are preferably equal to half the distance between two successive
poles CC and the reciprocating movement imparted to the feed pawl. K is
sufficient to move the pole carriage the said half distance. When the carriage
has been fed or moved forward sufficiently to present the series of poles in.
succession to the reciprocating shifting rods the feed mechanism is disengaged or
temporarily stopped by raising the feed pawl and stop pawl and the carriage is
then retrograded. This retrograde movement of the carriage may be effected by
means of a feed mechanism operating in the reverse direction to that above
described ; but it is preferred to effect it by means of a weight K* connected by
a rope with one end of the carriage. In order that the carriage may be stopped
when it has been retrograded by the weight K* a bumper L is provided in position
to be struck by the rear end of the carriage when it reaches its rearmost position ;
and it is preferred that the face of this bumper shall be a spring such for example
as a block of india rubber to prevent excessive jar.
In order to facilitate the operation of the apparatus the pole carriage is combined.
with means for disengaging the feed pawl and the stop pawl from the feed rack
when the pole carriage reaches the end of its forward movement and for permitting
the reengagement of the said two pawls with the feed rack when the pole carriage
reaches the end of its retrograde movement. For this purpose a slide N is
provided and is fitted with two pins n' (dotted in Figure 13) which are arranged
to move in inclined slots n n formed in a plate N¹ secured to the frame B of the
machine so that when the said slide is moved in a forward direction the inclina-
tion of the said slots causes the slide to rise and raise the pawls from the.
teeth of the feed rack and when the slide is moved backward the inclination of
the said slots compels it to move downward and lower the pawls into engagement
with said feed rack. In order that the said slide may be raised when the pole
carriage reaches the end of its forward movement a stop O is secured to the rear
end of the feed rack-K in a position to come in contact with said slide N and
compel it to move end wise and rise; and a spring pawl n' (Figures 3 and 13) is
provided to engage with the head n² of one of the pins and hold the slide in its
raised position with a yielding pressure.
In order that the said slide may be moved backward when the carriage reaches
the end of its retrograde movement a second stop O¹ is secured to the forward
end of the rack bar K in position to come in contact with the slide N and move
it backward and downward as the carriage reaches the end of its retrograde move-
ment; the spring pawl n¹ yielding to the pressure produced by the action of the
stop 0. In order to ensure the lifting of both pawls clear of the rack bar, it is
expedient to make the last tooth 8 of the rack bar a little higher than the other3
so that when the slide has been raised high enough to disengage the feed pawl K¹
from this last tooth, the stop pawl has been lifted entirely clear of the teeth of the
rack bar in advance of it.
When the carriage reaches the end of its forward movement the driving belt
should be shifted from the fast pulley I to the loose pulley I so as to stop
the operation of the shifting rods while the carriage is being retrograded. This
shifting of the belt may be done by hand; but in the apparatus represented in
the drawings a belt shipper is provided which may be operated either by hand or
by the movement of the carriage. The bar P of this belt shipper is fitted to slide
in brackets connected with the frame of the machine; and for the purpose of
enabling it to be operated by hand the bar of the shipper is connected by a link p¹
and an elbow lever p² with a hand shipper rod P' which extends preferably along
the main frame lengthwise thereof, and is supported in one or more guides p so
that it is within reach of the attendant standing at one side of the apparatus, and
can be readily operated by him. In order that the said belt shipper may be

page_text: operated automatically when the carriage reaches the end of its forward movement,
the belt shipper is combined with the carriage. To this end the bar P of the
shipper is connected by an elbow lever p* with the shipper rod P2 which extends
lengthwise of the frame of the machine and is supported thereon in one or more
guides, and this shipper rod P2 is provided with two stops p p, Figure 1, which
are moved alternately by means of the shipping arm p secured to the pole
carriage D. Hence when the pole carriage approaches the end of its forward
movement, the shipping arm p' acting upon the stop p moves the shipper rod P2
and the shipper P with which that rod is connected, so as to shift the belt from
the fast to the loose pulley, thus causing the cam shaft H and the reciprocating
shifting rods E, which are operated by means of the cams on that cam shaft, to
stop; and as the carriage approaches the end of its retrograde movement, the
shipping arm p comes in contact with the other stop so as to shift the belt
from the loose pulley 1, to the fast pulley I, and thus cause the reciprocating
shifting rods to commence operating anew.

The number of times which the carriage is moved to and fro may be counted by
the operator, but it is preferred to combine the pole carriage with an indicator either
directly or through the intervention of some other part of the apparatus moving in
accordance with the pole carriage, so that the indicator shall indicate automatically
the number of movements of the carriage. The indicator which it is preferred to
use has the form of a ratchet toothed disc R, which is moved the space of one tooth
for each forward movement of the pole carriage. For this purpose an elbow lever R¹
is supported upon the frame of the machine with its lower arm in position to be
struck by the end of the pole carriage D (or by a projection from it) as the carriage
approaches the end of its retrograde movement, and a spring is provided to move
the elbow lever R¹ in the reverse direction as the pole carriage is moved forward. The
distance to which the elbow lever can be moved by the spring is limited by a
pin; and the elbow lever is fitted with a hook which engages with the ratchet
teeth of the indicator with a yielding pressure incident to the action of a spring ².
The retrograde movement of the pole carriage causes the hook r³ to rise and take
hold of the next succeeding tooth of the indicator, while the forward movement of
the pole carriage permits the hook spring to draw the hook downward and thus
turn the indicator the space of a tooth. In order that the indicator may be prevented
from retrograding while its hook 3 is being moved to engage with a succeeding
tooth, the indicator is provided with a friction hand (shown in dotted lines at
Figure 2) which grasps the studs on which the indicator R turns; an index r¹ also
is provided to show the number of teeth of the indicator which have been moved
past it, thereby indicating the number of operations of the pole carriage. When
the pole carriage has been moved to and fro the desired number of times, the
operation of the apparatus may be stopped by turning the feed pawl (K¹) by hand
upward and backward so as to throw it out of engagement with the feed rack K ; but
it is preferred that the stoppage should be effected by the operation of the apparatus
itself when the pole carriage has completed its last forward movement. For this
purpose the mechanism represented in Figure 13 may be employed; a pin wheel S
having at least as many pin holes s' as the number of forward movements of the
pole carriage which are to be effected before the apparatus is stopped, being pivoted
to the frame of the apparatus. The pin wheel is fitted with a movable pin s, and
the slide N is provided with a pivoted hook S₁ which is held within the range of
movement of the said pin, s, of the pin wheel, by means of a guide s². In order
that the pin wheel may be moved, its rim is preferably formed into ratchet teeth
and a reciprocating hooks is provided to engage with these ratchet teeth in succession
and turn the wheel the extent of one tooth. The said hook is conveniently
reciprocated by means of a rocking arms which is fitted on its inner side with a
projection or pins that is within the range of movement of a depending projection **
from the pole, carriage; so that when the pole carriage approaches the end of its
forward movement, the hook s³ is moved forward to engage with the next succeeding
tooth of the pin wheel S. When the pole carriage commences to retrograde, its

page_text: depending projection s leaves the hook arm s¹, which is then pulled backward by
the operation of a spring s², so as to turn the pin wheel the angular distance between
two succeeding pin holes. A stop s is provided to limit the distance to which the
hooks can be moved by the operation of the spring s7. The movable pin s is placed
in the proper hole of the pin wheel S to be turned to the position in which it is
represented in Figure 13, during the forward movement next preceding the last
desired forward movement of the pole carriage, so that when the fed pawl K'
moves forward in engagement with the last tooth of the feed rack K, the pole
carriage, being moved thereby, has its depending projections brought in contact
with the projection of the hook arms and the hook is thereby moved forward to
the next succeeding ratchet tooth of the pin wheel. When then, the pole carriage
begins to move backward under the operation of the weight K the hook spring s
moving the pin wheel and the movable pin (s) carried by the pin wheel, causes the
latter to engage with the swinging hook S' and pull the slide N rearward sufficiently
to drop the pawls K' into engagement with the rack bar K and stop its further
backward movement with the carriage by the operation of the weight K*.
As the
belt shipper has been moved during the last forward movement of the carriage to
shift the driving belt to the loose pulley, the revolution of the cam shaft H has been
stopped previous to the commencement of the retrograde movement of the pole
carriage, so that when the slide N has been operated by the pin of the pin wheel as
above described and the retrograde movement has been checked by the dropping of
the pawls into engagement with the rack bar K, all parts of the apparatus remain at
rest until again started by the operator by shifting the movable pins to another hole
(or by turning the pin wheel S backward the number of holes corresponding with.
the number of operations of the carriage to be made in dyeing the next lot of hanks)
and by moving the slide N forward thereby lifting the pawls-so as to permit the
carriage to be retrograded by the weight K.
When the banks of yarn have been sufficiently dyed, they may be removed from
the apparatus by lifting each pole separately and carrying it away from the dye vat ;
but, as this separate removal of the poles would occupy considerable time it is
preferred to raise the pole frame D' with all its poles and with the hanks hanging
from said poles, bodily from the dye vat. In order that this may be effected readily,
it is preferred to fit the pole frame D' with eyes e¹ with which hooks connected with
lifting chains may be engaged, so that the said chains and the pole frame with which
they are connected may be raised by power and the pole frame may be transferred
from the apparatus, and that another pole frame, to the poles of which a new set of
hanks have been applied, may be transferred to the pole carriage.
The operation of the said apparatus is as follows:-Assuming that a pole frame D'
supplied with hanks of yarn hanging from its poles has been applied to the apparatus,
the pole carriage is permitted to be retrograded until the most forward pole of the
series is opposite the ends of the endwise reciprocating shifting rods E. As the
driving belt is shifted to the fast pulley I, by the time the retrograde movement of
the carriage stops, the shifting rods E, immediately commence to operate by the action
of the shifting cam E', and enter end wise into the cavity of the first pole and into the
bights of yarn hanging thereon. When the shifting rods have been entered their full
distance, they are raised by the lifting cam F2, and lift the hanks of yarn. During
this lifting movement the feed mechanism moves the carriage forward half the distance
between two successive poles; the first projection or grade t, of the feed cam K²,
operating for this purpose. When then, the shifting rods are lowered by the action
of the lifting cam F2, they lower the hanks of yarn into the dye vat in the space
between the lifting rods and the pole from which the hanks were lifted; the hanks then
hanging in the form of loops. When the shifting rods have been lowered, they are
withdrawn from the bights of the hanks; and as they are withdrawn, the stripper, J,
for each end wise reciprocating shifting rod, prevents the bights of the hanks from
moving outward of the dye vat with the shifting rod. As the shifting rods are with-
drawn end wise from the bights of the hanks with which they are engaged the hanks
drop into the dye vat. When the endwise reciprocating shifting rods have been

page_text: withdrawn, the second projection ', of the feed cam K³, comes into operation, and
operates the feed pawl K¹, to move the pole carriage the distance of one tooth of the
feed bar, thus bringing the second pole of the series opposite the ends of the shifting
rods, so that the hanks of yarn hanging on the second pole may be shifted in turn.
The operation of shifting the hanks hanging upon each pole is repeated until the pole
carriage reaches its most forward position and the yarn upon all the poles has been
shifted, whereupon the pawls (K1, k,) are thrown out of engagement as previously
described (by the operation of the slide N) and the carriage is retrograded by the
weight K, to have the shifting of the hanks of yarn repeated. The retrograde move-
ment of the carriage with the hanks or skeins of yarn hanging upon the poles,
causes the said hanks or skeins to trail through the dye liquor, which there-
fore circulates through the said hanks or skeins; and when the shifting is repeated
two or more times the trailing operation (without shifting) alternates with the
shifting operation. When the movements of the carriage have been repeated the
required number of times, the operation of the machine is stopped, the dyed hanks of
yarn are removed from the dye vat, and fresh hanks are put in their places.
During the retrograde movement of the carriage, the trailing of the hanks of yarn
in the dye liquor operates as a brake to slow down the movement of the carriage by
the action of the weight K, and the amount of this weight should be adjusted in
accordance with the number of hanks which are to be dyed at any one time so that the
carriage may not retrograde too rapidly. As the number of hanks dyed at any one
operation may vary it is preferred to construct the weight in sections, as represented
at Figure 2, more or less of which sections may be used as found expedient for the
number of the hanks of yarn. The presence of the hand shipper rod P¹, at the side
of the apparatus enables the attendant to stop the operation of the apparatus at any
time in case such stoppage be expedient.
It is possible that the end wise reciprocating shifting rods when lowered between the
poles may from some accident be not withdrawn to their full extent, in which event
the next feeding movement would bring the next succeeding pole against the shifting
rod and bend it. In order to provide against risk of injury from such a contingency
and to give the attendant time to notice such difficulty, the lifting cam F2, is fitted
with a second but low lifting grade v¹, Figure 11, which makes a second but slight
lift and lowering of the shifting rods E, after they have been lowered by the main
grade b, and raises them free of the edges of the next succeeding pole, and thus
prevents injury in case the end of the shifting rod has not been sufficiently withdrawn
to clear the pole.
It is preferred to apply a counterpoise X, Figure 1, to counterbalance the weight
of the hanks of yarn, and to connect this counterpoise with the rock shaft, G', by
means of an arm X!.
Although the above described apparatus embodies all parts of the invention in the
forms in which it is preferred to construct them, it is evident that more or less of
those parts may be used as found expedient. Thus for example, the combination of
the belt shipping device with the carriage may be broken by removing the stops på
and p, so that the apparatus will not be stopped by its own operation when the
carriage is to be retrograded, without affecting the combination of the pole carriage
with the end wise reciprocating shifting rod or rods. So also one endwise reciprocating
shifting rod may be removed, leaving one only to be operated. The main frame
also may be constructed complete for use with more or less of the operating
members, and may be sold without the dye vat leaving the purchaser to add the dye
vat in his dye house.

tion and in what manner the same is to be performed I declare that what I
