Improved Apparatus for Mechanically Dyeing Combed Wool in
Bobbins, Raw Wool, and Cotton.
I, ALPHONSE AUGUSTE VANZEVEREN, Dyer, of Tourcoing, in the Republic of
France, do hereby declare the nature of this invention and in what manner tho
same is to be performed to be particularly described and ascertained in and by
the following statement:.
-
This invention for an improved apparatus for mechanically dyeing combed
wool in bobbins, raw wool and cotton has for its object to provide a dyeing
apparatus of this class which is simple, inexpensive, very easily and quickly
managed and without incurring any great expense can be applied to existing
dyeing becks.
In the accompanying drawings Fig. 1 is a longitudinal sectional elevation of
dyeing apparatus constructed according to this invention. Fig. 2 is a cross section
of the same. Fig. 3 is a longitudinal section of a bobbin pail. Fig. 4 is a plan.
thereof and Fig. 5 is a sectional elevation of part of a tank with two pails mounted
thereon.
The apparatus consists of a. wooden vessel A. of rectangular shape, divided into
two compartments by a strong vertical partition B. In the sides of the vessel
as well as in the cross piece or partition B are rails C having semi-cylindrical
recesses at different points in which the trunnions D of the bobbin pails or pots E
engage.
The bobbin pails or holders E are cylindrical in shape and made of copper.
They consist of three parts, the central part 1 being the bobbin chamber. The
two other parts 2 and 3 likewise of cylindrical shape are separated from the bobbin
chamber by the circular horizontal partitions I and S which are perforated to
allow of the passage therethrough of the dyeing liquids.
The lower partition I is fixed by means of angle irons or simply soldered to the
pail or holder.
The upper partition S which is movable has on its cut out perimeter pro-
jections which are inserted in the corresponding recesses of the pail or holder
and on being rotated engage in the groove formed by the upper stamped rims G
Figs. 3 and 4. A handle H facilitates the management of the partition S.
A beck or tank K of small dimensions, placed in the upper part of the apparatus,
longitudinally thereof, receives the dyeing liquids from a suction and forcing.
pump N. Cocks L allow of the passage of the liquids through discharge pipes O
into the upper part of the bobbin pails or holders E.
The application of dyeing liquids to the bobbins is regulated in regard both to
quantity and direction by means of the cocks L.
When the bobbins subjected to the action of the bath are considered to be
sufficiently dyed on one side, the holders are raised out of their bearings and
moved along the rails C into a position where they can be rotated freely and are
caused to rotate on their trunnions in such a manner that the positions of the
ends of the holders are reversed, the end of the holder which has hitherto been.
directed upwards being now directed downward and vice versa. The displacement

page_text: of the holders in order to allow of their rotation is only necessary in cases where
the dyeing beck is not sufficiently large; whilst when the beck is larger the
holders are simply turned without being displaced, as shown in Fig. 5
The supply of dye to the water to, form the dyeing liquid is effected automatically.
A cask or container T with perforated bottom contains the dye wood, the hot water
first put into the vessel. A is drawn up by the pump N, and enters the vessel K,
running off into the cask T through the pipe where it becomes charged with
dyeing material and colored, then returns to the vessel A through the pipe V in.
order to be drawn up again by the pump and thereby forced into the vessel K.
From the last named it is conveyed through the discharge pipes O on to the
bobbins or pails E.
In case it should be considered necessary to darken the shade of the bobbins,
and the dye woods put in the cask should not furnish sufficient colouring
material, the dye woods are removed from the cask T and a fresh quantity of
dye wood introduced into the latter.
The dyeing with this apparatus is thus effected in two operations, . with. á
reversing of the bobbin holders.
The circulation of the liquids is effected easily and successively on the two sides
of the bobbins by the forcing action of the pump. The liquids simply deposit
the dyeing material on the wool without overloading it; the thread after dyeing
preserves its condition as before the dyeing and the material remains unchanged.
This apparatus dispenses with a considerable amount of hand labour as one
man can manage a vessel containing 16 bobbins, and further, the work of the
one man consists simply in causing the bobbin pails to swing, an operation which
is effected about every twenty minutes.
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 apparatus for effecting the mechanical dyeing at two successive operations,
of combed wool, raw wool or cotton consisting of the lower tank, the bobbin pails
or holders mounted in the tank, the upper tank or beck, the discharge pipes
connected therewith, the cask or container for the dye woods, and the means for
circulating the dyeing liquid substantially as described.
2. The means for automatically supplying dye to the water to form dyeing
liquid substantially as described."
3. The improved apparatus for mechanically dyeing combed wool in bobbins,
raw wool and cotton, substantially as described with reference to the drawings.
