Improvements in Machinery for Dyeing Textile Fabrics in Hanks
or Skeins.
I, PAUL VILLETTE, Manufacturer of Machinery, Lille (Nord), in the Republic
of France, 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 improvements in machinery for dyeing textile fabrics
in hanks or skeins, and has for its object to provide a machine that shall traverse
the skeins through the dyeing tank and impart such motion to them during
immersion that a thorough dyeing takes place.
To effect this, two operations are comprised:
1st. The immersion of the hanks or skeins in the bath with intermittent rotary
motion of the hank or skein carriers.
2nd. Intermittent stirring of the skeins or hanks in the bath with alternate
rotation of the carriers.
These two alternating operations produce an excellent dyeing effect.
In the accompanying drawings Fig. 1 is a side elevation of a dyeing machine
constructed according to this invention. Fig. 2 is a right hand end elevation of
same, Fig. 3 is a plan of the left hand end of Fig. 2. Fig. 4 is an end elevation
showing the means for disconnecting the driving gear. Fig. 5 is a left hand
elevation and Fig. 6 is an elevation showing the mechanism for producing
intermittent rotation of the skein carriers, and Fig. 7 is a longitudinal sectional
view of the machine.
It will be easily understood that in order to thoroughly permeate a fresh
portion of the hanks with dyeing material, such portion should remain immersed
for some time and that, during this period of arrested rotation of the carriers A
and of the stretchers B, these should effect a stirring of the immersed portion of
the hanks. The duration of this stirring operation is regulated automatically
according to the nature of the textile materials to be dyed.
In order to effect these two successive and not simultaneous operations, the
following parts of the machine are set in motion (see Figs. 1 and 5).
Carriers A are first put into engagement and then out of engagement at one
end by means of sleeve couplings C with projections or catches I and a cheek
held between two reglets 1). The shafts of the sleeve couplings carry a pinion E
which receives rotary motion that has been transmitted to the shaft F by the
driving shaft G through the medium of the gearings 1, 2 3. In the engaging
operation the projections or catches I are brought into contact with the similar
parts I in the disengaging operation, the parts I are moved away from the
parts I owing to the sliding of the couplings C on their axes following the
displacement of the reglets D.
Figs. 1 and 6 show how the displacement of the reglets D is effected. For
this purpose a shaft H connected to the shaft F by endless screws and pinions 4,
5, 6, 7 carries two cams O placed apart from each other and acting on a
roller P forming part with a bent lever R, linked to another and oscillating

page_text: lever S, which acts on the reglets D. A spring Q exercises a tensible force on D
and constantly keeps S and 1) in contact with one another.
When the large radius of the cam O is turned towards the roller P the
coupling C is out of engagement consequently the carriers A are not rotated.
If on the contrary the small radius of the cam 0 is turned towards the roller P
the upper part of the lever S moves to the right the reglets D acted upon by
the spring push the coupling C the catches or projections of which then come
into contact with the parts I whence there is a rotary motion of the carriers A.
The intermittent action of the parts employed for stirring is effected in the
following manner:- (see Figs. 2 and 3). The shaft T carrying the plate or
tube u regulating the connecting rod V which takes part in the operation of
stirring, has a coupling sleeve with catches or projections X. The displacement
of this coupling is effected by a bent lever Y which is acted upon by cam Z
In the axis of the shaft T is a shaft J which supports at one end a plate or
table with catches or projections X¹ which can be put into engagement by the
coupling X and, at the other end, receives motion from the shaft F by means
of bevel wheels 8 and 9.
The connecting rods V as indicated above regulate the stirring of the hanks or
skeins by the reciprocating motion which they transmit to oscillating frames M
suspended across a slide or carriage N which bears the carriers A and serving
further for removing them from the bath.
The frames M are suspended from the upper part of the carriage N so as to
swing freely when operated by the rods V and for this purpose bars 10 are
pivotted to the frames said bars being suspended through a pivotted adjustable
connecting piece 11 from a link 12 pivotted on an inwardly directed arm 13
carried by the carriage N as shown in Fig. 5.
The position of the cam O which produces the action or inaction of the
carriers A and that of the cam which determines the stirring or non-stirring
motion is regulated in such a manner that these two operations are effected
successively and never simultaneously so as to ensure perfect dyeing.
The skeins are lowered into the tank where the successive operations of rotating
the skeins and intermittent stirring are accomplished during immersion, they
are then raised out of the tank and removed.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is―
1. The dyeing machine for dyeing textile fabrics in hanks or skeins, based
on two alternating operations, viz., a rotary motion of the portions of the hanks
or skeins after immersion in the bath, followed by the stirring of the hanks or
skeins in such bath.
2. The mechanical means herein before defined and described, for securing the
result previously specified.
