Improvements in Apparatus for Dyeing Yarn.
I IRA FRANKLIN PECK, of 14 Temple Street, Providence, Rhode Island, United
States of America, Inventor, do hereby declare the nature of my invention for
"IMPROVEMENTS IN APPARATUS FOR DYEING YARN" to be as follows:-
In dyeing the yarn contained in cops which are immersed in the dyeing liquor
upon hollow spindles through which the said liquor is made to pass by means of
a suction pump, it is very desirable to be able to operate upon a few spindles at a
time, while a comparatively large number of spindles are being held in the vat of
dyeing liquor, ready to be acted upon alternately with the others, and by this
means a uniform shade of color will be produced in all of the cops in the vat,
and the time for properly dyeing the yarn will be greatly lessened.
My invention for this purpose consists in the employment of a spindle-holder
preferably of a cylindrical construction, and having an outer shell provided with
longitudinal rows of perforations, into which are inserted short tubes which are
adapted to receive the inserting shanks of the perforated hollow spindles, upon which
the cops are placed.
The perforated shell is provided at one end with a hollow head, which may be
secured to the end of the shell by means of a screw thread, and provided with a
passage which extends to an opening at a coupling joint to which a suction hose.
can be removably attached by means of a clamp, the said hose being attached to
a suitable pump for drawing the dyeing liquor through the cops.
At the opposite end of the outer shell is secured a head provided with a hollow
hub, and within the bore of the cylindrical shell, and closely fitting the same, is
placed the hollow valve which extends from end to end of the shell, and is preferably
provided upon its opposite sides with openings, so that the opposite longitudinal
series of cop spindles will be acted upon by the vacuum produced by the pump,
in the chamber of the carrier, while the remaining spindles around the shell will
be unacted upon.
The valve stem which passes through the above mentioned hollow hub, is pro-
vided with a suitable stuffing gland, and upon the projecting end of the stem is
preferably attached a pinion gear, by means of which the valve may be rotated
within the shell, to successively cover and uncover the openings which lead to the
hollow spindles, the shell to which the said spindles are attached being at the same
time held stationary, by means of a guide-stem which enters a suitable slot opening
in an angularly shaped stationary guide, so that as the hollow valve is turned
within the shell, the several longitudinal series of hollow spindles which project
radially from the periphery of the shell will be successfully brought under the
action of the vacuum employed for causing the dyeing solution to flow through
the cops placed upon the spindles, and instead of arranging the valve to turn upon.
its axis, the same may be made to slide endwise to cover and uncover the openings
in the outer shell, the said openings in the outer shell and in the hollow valve having
been first suitably arranged for that purpose.
My invention also includes an arrangement of vats containing the required
dyeing solutions, with carrier chains running over the vats upon sprocket wheels,
the said chains being located at opposite sides of the vats, and adapted for the
attachment of the spindle carriers thereto at proper intervals.
The movement of the said chains by suitable means being adapted to carry an
attached spindle carrier over the edge of the first vat of the series, and downward into
the dyeing liquor, to be there subjected to the action of the suction pump through an
attached hose, the shell of the carrier being held stationary by means of fixed guides

page_text: arranged at the sides of the vat, while the valve is being turned, so that the liquor
will be successively drawn through the several rows of spindles attached to the carrier ;
and in order to turn the valve in the carrier, & preferably provide a segment gear at
one side of the vat, which will engage with the pinion gear upon the end of the valve
stem, and by means of a hand lever and a notched guide move the said segment gear
as required, the said gear being placed upon a short shaft which extends through
the side of the vat, and is provided with an arm to which suitable connection is
made.
'
When the cops have been thus acted upon in the first vat, the carrier chains are to
be moved unitedly forward, carrying the carrier upward out of said vat, and over into
the second vat; but as the carrier is brought out of the dyeing liquor of the vat, the
pinion gear upon the valve stem will come into contact with a segment gear which
is in connection with an operating lever, by means of which the valve can be operated
to free the cops from the dyeing liquor, by the continued action of the pump, and this
operation will be repeated at each vat until the cops have been properly dyed.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Dyeing Yarn.
I, IRA FRANKLIN PECK, of 14 Temple Street, Providence Rhode Island, United
States of America, Inventor, do hereby declare the nature of my invention for
"IMPROVEMENTS IN APPARATUS FOR DYEING YARN," and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
In dyeing yarn contained in wound cops which are immersed in the dyeing liquor
upon hollow spindles, through which the liquor is made to pass by means of a suction
pump, it is very desirable to be able to operate upon a few spindles at a time, while a
comparatively large number of spindles are being held in the vat of dyeing liquor
ready to be acted upon alternately with the others, and by this means a uniforui shade
of color will be produced in all the cops in the vat, the time employed for properly
dyeing the yarn being also greatly lessened. For this purpose my invention consists
in the employment of a spindle-holder provided interiorily with a valve which is
adapted to control the passage of the dyeing liquor through the several cops, so that
while a comparatively great number of cops are in the dyeing liquor, only a portion of
the same will be acted upon by the pump at any given time; and it also consists in
the devices employed for moving the spindle carriers from one vat of the dyeing
apparatus to another, and in the devices for causing the required movement of the
valve of the spindle carriers, as hereinafter fully set forth.
Fig. 1, represents the top view of a cop dyeing apparatus embodying my invention.
Fig. 2, represents a partial side elevation and vertical section of the same, showing
the mechanism for adjusting the valves of the spindle-carriers.
Fig. 3, represents a transverse section taken in the line y y, of Fig. 1.
Fig. 4, represents a longitudinal section of the spindle-carrier.
Fig. 5, represents a transverse section of the sanie.
Fig. 6, represents a face and an edge view of one of the fixed side guides for holding
the spindle-carrier firmly in position, while the valve is being rotated, the stem-guide
of the carrier being shown in section.
Fig. 7, represents an enlarged side elevation of the link of the chain which forms a
bearing for the stem of the carrier.
In the accompanying drawings, A1, A2, A3, are adjoining vats, adapted to hold the
several solutions required to properly dye the yarn, and which are supported at the
proper height above the floor by means of the posts B, B. At the upper ends of

page_text: the posts B, B, are placed the bearing boxes C, C, in which are placed the chain
driving shafts D, and upon one end of each of the shafts D, is placed a bevel gear E,
which engages with a pinion F, placed upon the shaft G, so that, upon the rotation of
the shaft G, by any suitable means, the shafts D, will all be rotated in the same
direction.
Upon the shafts D, at the inner side of the boxes C, C, are secured the sprocket
wheels H, H, and upon the shafts D¹ supported by the brackets I which are attached
to the end posts B, are placed the loose sprocket wheels J, and upon the sprocket
wheels H and J, at opposite sides of the machine, are placed the chains K, K, to which
the spindle carriers L are to be attached, a link c at proper intervals in the chain
being made too loosely embrace the end portion of the carrier as shown enlarged in
Fig. 7.
The spindle carrier L is provided with a perforated cylindrical shell A into the
perforations a a of which are inserted the short tubes b, b, the said tubes being adapted
to receive the tapered inserting shank of the hollow spindle d upon which the cop is
to be placed.
The shell A is provided at one end with the hollow head B₁ which may be fastened
upon the end of the shell by means of a screw thread, and which is provided with a
passage e, which extends to an opening fat the coupling joint g. The hose D³ which
is to be connected to a suitable pump for drawing the dyeing solution through the cop,
is provided with a hollow joint piece C¹ which is held against the head B¹ at the
opening to form a tight coupling joint at g, by means of the hand clamp E'. At the
opposite end of the shell A is secured the head B³, provided with the hollow hub h, and
within the bore of the cylindrical shell A, and closely fitting the same, is placed the
valve F, which extends from end to end of the shell A, the said valve being provided
at its opposite sides with the openings i, i, so that the opposite longitudinal series of
spindles d, d, will be acted upon by the vacuum in the chamber G', while the
remaining spindles around the shell A will be unacted upon.
The valve stem j passes
through the hollow hub h which is provided with a stuffing box k, and upon the pro-
jecting end of the stem j is placed a gear m by means of which the valve F may be
rotated within the shell A, to successively cover and uncover the openings 6¹ to
the spindles d, d, the shell A being at the same time held stationary by means of
the angularly shaped side-guide M and guide bar M2, which hold the flattened
stem-guide, of the carrier in its two positions, as shown in Fig. 6, and as the
valve F is turned within the shell A the several longitudinal series of spindles d
which project from the periphery of the shell, will be successively brought under
the action of the vacuum employed for causing the dyeing solution to flow through
the cops placed upon the spindles.
Upon the inner end of a short shaft N, extending through the side of the vats, with
a stuffing box bearing, is placed the segment gear O, which is adapted to engage
with the gear m connected with the valve F; and upon the outer end of the shaft N
is placed the arm P. The several arms P at the outside of the vats, are connected
to each other by means of a rod d¹, so that the several shafts N and segment gears O
can be moved equally and in unison with each other. To the end of one of the
shafts N is attached the hand lever Q provided with a pin e¹ which is adapted to
enter the holes f¹ made in the side of an arc R attached to the post B; and the
holes flare so graduated, that when the hand lever Q is moved from one hole to
the next adjoining hole, the connected segment gears will be moved through a
space sufficient to cause the closing of one series of apertures leading to the spindles,
and the opening of the adjoining series of apertures; and by the movement of the
hand lever Q from hole to hole on the arc R, the spindles d will be brought
successively under the action of the pump employed to produce a vacuum in the
chamber G, of the valve F.
Upon the inner end of the short shafts N' which extend through the side of
the several vats, is placed the segment gear O₁ which is adapted to engage with the
gear m, connected with the valve F of the spindle carrier, and upon the outer end
of the shaft N', is placed the arm P¹, from which connection is made with the

page_text: arm P² attached to the corresponding shaft N, at the lower portion of the vat by
means of the connecting rod d², so that upon the movement of the segment gear O
in either direction by the movement of the hand lever Q, a corresponding movement
will be imparted to the segment gear 0¹.
In operating with the machine, the vats A1, A2, A3, are to be filled with the
properly graduated dyeing solutions and a carrier A provided with its complement
of spindles and attached cops, is to be secured to the chain by means of the
specially arranged links c which are each provided with the hinged arm s secured at
its outer end by means of a pin t, and adapted to embrace the cylindrical bearing;
of the carrier, so that, when the carrier is in any position out of the angularly shaped
side guides M it may be rotated in the bearings formed by the opposite links c
of the chains K, K, and when the pump hose D2 has been secured in place by
means of the clamp E¹, then by turning the shaft G in the proper direction the
carrier which may be attached to the chain at the line a a, Fig. 2, will be
carried forward into the first vat A¹ of the series the gear m being carried down
by the weight of the carrier into contact with the segment gear O, and the flattened
upwardly projecting stem-guide 7 of the carrier, being held in the notch n at the
apex of the angularly shaped guide M; so that, the shell A of the carrier will be
firmly held pending the movement of the valve F as before described, by means of
the hand lever Q. When the cops upon the first attached carrier have been
successively treated to the circulation induced by the pump, and have become
thoroughly saturated with the solution in the first vat, then by turning the shaft G
in the proper direction, the first carrier will be carried upward out of the dyeing
liquor so that the gear m will be carried into ongagement with the segment gear
with the stem-guide of the carrier held in the space between the arm m² of the
guide M, and the guide-bar M², which will prevent the shell A, of the carrier,
from turning with the valve, and then when the suction pump is mado to draw
air through the several rows of cops by the progressive movement of the valve F
by means of the hand lever Q, which operates the segment gear O¹, the surplus
dyeing liquor will be drawn from the several cops preparatory to their immersion
in the liquor of the succeeding vat. The pump hose D is then to be removed
and a second carrier with its attached spindles and cops is to be attached to the
next succeeding link c, of the chains above the line a a, and a separate pump hose D'
is to be attached to each of the two carriers, then by turning the shaft G, the first
carrier will be carried with the chains from the first vat over into the second vat,
and the second carrier will be carried into the first vat to engagement with the
segment gears 0, 0, so that both carriers will be in proper position for the move-
ment of their respective valves, by means of the hand lever Q; and when the cops
upon the spindles of both carriers have been sufficiently treated by the forced passage
of the solution in the vats through the immersed cops, the two carriers are to be
raised into engagement with the segment gears O¹, to draw the dyeing liquor from
the cops previous to their insertion into the next dyeing solution, and then the
separate pump-hose D2 is to be removed from each, and another carrier with its
attached spindles and cops is to be attached to the next succeeding attaching link c
of the chains above the line a a, and a separate pump-hose D2 is to be attached to
each of the three carriers, then, by turning the shaft G, the first carrier will be
carried over into the third or finishing vat, the second carrier will be carried over
from the first vat into the second, and the third carrier will be carried over into the
first vat, to engagement with the segment gears 0, 0, 0, and then, by means of
the band-lever, the valves of each of the carriers will be operated simultaneously
until all of the cops have been successively treated, and thoroughly saturated with
their respective solutions, and thereafter upon the attachment of another carrier with
its charge of spindles and cops with the withdrawal of the surplus dyeing liquor
from the cops, the disengagement and reattachment of the pump hose D2, and the
forward movement of the chains as before, the first carrier with the spindles d and
their completely cyed cops, can be removed from the chains, the said carrier having
passed from the third vat to a convenient position at the end of the apparatus, and

page_text: the further operation of the apparatus will be continuous, a carrier having its
spindles provided with fresh cops being supplied to the chains at one end of the
series of vats, while the carriers with the completely dyed cops can be removed
from the chains at the opposite end of the same.
Or if preferred, a carrier can be permanently held in each of the links c of the
chains as shown in Fig. 3, and the fresh cops can be supplied to the carrier at the
entering end of the apparatus and the properly dyed cops be removed from the carrier
at the discharging end of the same, whereby the operation will be continuous, the
forward movement of the carriers being arranged at proper intervals.
Instead of arranging the valve F of the carrier, for rotary movement within the
shell A, the same may be made to have an end wise movement to cover and uncover
the apertures leading to the several spindles.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. In an apparatus for dyeing yarn in cops, the combination with the vats, of
the spindle carrier chains, the spindle carriers arranged at intervals upon the chains,
and the fixed guides in the vats, for the opposite ends of the carriers, substantially
as described.
2. In an apparatus for dyeing yarn in cops, the combination with the vats, of
the spindle carrier chains, the spindle carriers arranged at intervals upon the chains,
and the movable pump-hose or pipe, by means of which the required circulation of
the dyeing solution is effected, substantially as described.
3. In an apparatus for dyeing yarn in cops, the combination with the vats, of
the spindle carrier chains, the spindle carriers arranged at intervals upon the chains
and provided with an interior valve having a gear upon its stem, the attached
pump hose or pipe, the fixed guides in the vats, for the opposite ends of the
carriers, and the connected segment gears for operating the valve of the carriers,
and means for holding the valve in its required positions for successive operation
upon the cops, substantially as described.
4. In an apparatns for dyeing yarn in cops, the combination with the vats, of
the spindle-carrier-chains provided with links which form suitable bearings for the
carriers, the spindle-carriers loosely held in the carrier bearings of the chain, the
fixed guides in the vats, for the opposite ends of the carriers, and the stem-guide
for holding one end of the carrier stationary, while the valve is being operated,
substantially as described.
5.-The combination with the perforated shell provided with the hollow spindles,
of a valve located within the hollow shell and adapted to open and close the
passages to the hollow spindles, successively, so that the dyeing liquor will pass
through a portion only of the spindles at any given time, substantially as described.
