PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Dyeing or Bleaching Textile
Materials.
I, JULES BERTRAND-LEPLAT of Tourcoing, Nord, France,, Machine; Builder,
do hereby declare the nature of this invention to be as follows
The improved apparatus which forms the subject of 'this invention is specially
intended for dyeing slivers of cotton or other textile materials in the state in which
they leave the carding machine or other machine which delivers.continuous slivers;
it is, however, also applicable to bleaching textile materials.
The work is effected by the circulation of different liquids through the material
which is held in boxes or cases.
The apparatus consists of an open vat of wood or metal with a falso or double.
bottom dividing it into two compartments. This false bottom has large holes in
which are fitted slightly conical sockets. In these sockets are fitted cases or boxes
containing the textile material to be dyed, the boxes having conical tubes at bottom
which fit exactly into the conical sockets of the false bottom. The number of the
boxes is optional; each box is provided at the upper part with a ring or handle to
permit of its being raised by any suitablo lifting apparatus and removed from the
vat so that the dyed cotton may be taken out and replaced by a fresh supply. A
suitable pump communicates with the vat at the upper and lower parts by means
of pipes.
The pump draws the liquid from the lower compartment of the vat and discharges
it into the upper compartment, thereby causing the boiling, dyeing, washing, or
other liquid to circulate through the textile material, the boxes being. with this
object perforated. The boxes will preferably be made with one side removable
for the introduction and withdrawal of the slivers, the removable side, being secured
by screws.
There may ybe any desired number of compartments in one box, and each com-
partment will have a removable side. If there are for example two compartments
a vertical space will be left between them so that the liquid after traversing, the
compartments transversely will descend the space between them and then pass
through the tube at bottom into the lower compartment of the vat. The perfora-
tions in the boxes are limited so that the liquid is compelled to pass through the
textile material.
Instead of having a false bottom to the vat I can fit it with a single collecting
pipe or a gutter, at bottom.
"
Among the advantages of the improved apparatus I may mention the following:
The facility for lifting out test samples while the work is proceeding, the vat being
open at top. The power of dispensing for a time with the use of one or more of
the boxes seeing that if there is not sufficient material the conical sockets of one or
more of the boxes can be plugged. The simplicity of the apparatus and the absence
of all mechanism so that repairs are saved. There is almost no waste or prejudicial
space as the vat is almost entirely filled with the boxes; this is important because
it allows of the use of very concentrated baths, and the dyeing material is, thus
economized which is not the case with apparatus hitherto constructed. 1. The liquid
passes transversely through the material and dyes it uniformly.
The same apparatus will answer for dyeing or bleaching textile materials in cans
before spinning, or on bobbins such as are used in fly frames or in winding machines,

page_text: or on cops, or in the form of balls, the shape of the boxes or cases being suitably
modified.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Dyeing or Bleaching Textile
Materials.
I, JULES BERTRAND-LEPLAT, of Tourcoing, Nord, France, Machine Builder,
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:-
The improved apparatus to which this invention relates is specially intended for
dyeing slivers of cotton or other textile material in the state in which they leave
the carding or other machine which delivers continuous slivers. The apparatus
may however be used for dyeing textile material in cans or cops before spinning, or
in thread or yarn after spinning, or in the condition of woven fabric.
Also instead of dyeing, washing scouring or bleaching may be effected in the
same apparatus, according to the character of the liquor employed.
I shall describe apparatus according to my invention referring to the accom-
panying drawings.
Fig. 1. is a longitudinal and Fig. 2. is a transverse section and Fig. 3. is a plan
of the whole apparatus, Fig. 4. is a sectional plan of one of the double boxes.
A is an open vat having under its bottom B a compartment C which may be, as
shewn, in the form of a rectangular tube closed at the one end and connected at the
other to the suction of a rotary or other pump G. In the bottom B are a number
of slightly tapered sockets E fitted to receive tubular plugs D projecting from the
bottoms of boxes K, of which there may be any desired number. Each box K is
made in two compartments separated by a double vertical partition T of perforated
metal plate, the space between the two perforated plates being in direct communi
cation with the tubular plug D. Each compartment has its outer side closed by a
removeable perforated cover F which is held by flanged screws S at the top and
the bottom. Each box K is made with a handle H, so that by means of a hand
winch L with longitudinally moveable barrel M and a cord passing over a roller N
any one of the boxes K can be raised out of the vat. The discharge of the pump G
communicates with the upper part of the vat A, which is charged with the dyeing
or other liquor. By partly unscrewing the screws S the covers F of each box K.
are removed, and the two compartments of the box are charged with the textile
material to be operated on, whereupon the covers F are again secured and the
charged box is lowered into the vat, its plug D fitting into the socket E. By
means of the pump G the liquor is drawn into each box through its perforated
covers F and through the perforated partitions T, passing on its way through the
textile material, and down through the plugs D and tube C to the pump, by which
it is, returned to the upper part of the vat to circulate again through the material.
By means of the winch any one of the boxes K can be raised to examine its
contents and ascertain whether the process has been carried sufficiently far.
Each of the boxes K, instead of having only one pair of compartments, might
have two pairs. The vat A might be made to accommodate a less or greater number
of boxes K and the tube C might extend' the whole width of the bottom of the vat.
Also, the tube C might be connected to the discharge of the pump, the suction
being connected to the upper part of the vat A, the circulation of the liquor being
thus reversed.
The apparatus above described being simple and free from complicated mechanism,

page_text: is not liable to derangement, it gives great facilities for operating, as any box can
be freely lifted for charging discharging or examining its contents, and, when there
is not sufficient material to require all the boxes to be in use, some of the sockets E
can be plugged. When in full use, the vat is almost entirely filled with the boxes,
leaving little free space, consequently very concentrated baths can be employed,
thus effecting economy of the dyeing or other substance used for charging the
liquor.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. Apparatus for dyeing or bleaching textile materials consisting of a vat con-
taining a number of vertically removeable boxes, each box made in compartments
with perforated partitions and covers through which, by means of a pump, liquor is
caused to circulate so as to pass through and act on the textile material with which
the compartments are charged substantially as described.
2. In apparatus such as is above referred to, the construction of each box with a
middle space between its perforated partitions, communicating through a tubular
taper plug and socket at the bottom with a passage leading to the circulating pump;
substantially as described.
