SPECIFICATION.
Apparatus for use in Treating and Dyeing Cotton Slivers, Rovings,
or Cops, and other Textile Materials.
I REGINALD HADDAN of the firm of Herbert & Co. Patent Agents of 18 Bucking-
ham Street, Strand W.C. London in the County of Middlesex, Civil Engineer do
hereby declare the nature of this invention, a communication to me from abroad by
Jules Bertrand-Leplat of Tourcoing in the Republic of France Manufacturer, and in
what manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
This invention consists in an apparatus or machine embodying the improvements
hereinafter claimed and adapted to receive and submit to the various preliminary and
actual processes of and connected with dyeing, more or less manufactured or finished
textile materials such as cotton slivers, roving or cops or any textile materials made
up, in skeins or wound bobbins on cylindrical or conical tubes, without derangement
of the fibres or threads, and without necessitating any handling or moving of them
during the continuance of the process until they are to be removed dyed.
Sheet 1 of the accompanying drawings illustrates the improved apparatus, Fig. 1
being a plan. view thereof. Fig. 2 a vertical section. Fig. 3 a cross section through
the dyeing vat. Figs. 4 to 7 detail views.
-
Sheet 2 illustrates the apparatus as modified in certain parts hereinafter referred
to, the same figures representing equivalent parts to those shown on Sheet 1.
The apparatus comprises, a reservoir or vat A for holding the dye bath—a vat B
for receiving the material to be dyed, in which all' preliminary treatment connected
with the process of dyeing also takes place; and a pump and special arrangement of
pipes for transferring the bath liquor to or from the vat B and circulating the bath
liquor therein.
The vat B contains a rotary drum or cylinder, formed of two discs or head
frames. D D of suitable strength and design supporting a periphery formed of a
number of parallel U shaped holders E rivetted together on their sides so as to form
a continuous mantle for the drum-so that the only communication between. 'the
interior and exterior of the drum is through. the lower semicircular parts F of
said holders which are perforated-These holders are designed to receive the slivers
or roving to be dyed, previously rolled in a covering of fabric intended to completely
fill the semicircular part of each compartment or holder E and cover all the
perforations therein. The material is retained in each compartment by metal cover
plates G, perforated and shaped to fit the holders-Each cover plate G is provided at
the ends with lugs H perforated with a series of holes. so, that the plates G
may be fixed by plugs or bolts, with more or less pressure upon the material in, the
holder.
The drum is arranged to revolve in the vat B and at one end is provided with a
trunnion I lying in bearing J fixed on the inner wall of said vat, and at the other
end with the hollow shaft K projecting through a stuffing box in the opposite wall of
the vat and provided with a spur wheel to which a slow movement is given by a
screw on the shaft N revolved through pulley P-The end of the shaft Kis
provided also with a stuffing box Q. through which the stationary tube R passes to
afford communication with the interior of the drum in the vat B.
The pipe R passes to the three way cock S. by which the former may be placed
in communication with the suction pipe U or the force pipe T of the pump C; on
an elbow in the pipe T is pivoted the delivery pipe V by means of which the pump

page_text: may be used to throw liquid either into the vat B or reservoir A by swinging the
pipe V over the one or the other vat respectively.
The suction pipe U is also provided with a branch connecting with a three way
cock for affording communication between the pump C' and the bottom of either the
reservoir A or the vat B.
The material having been placed in the holders E of the drum and secured by the
covers G by gradually turning the drum by hand or power so as to bring each
compartment uppermost for filling until the whole drum is thus stocked; the dye
bath is then transferred to the vat B by means of the pump, by opening the suction
to the base of the dye bath reservoir (or reservoir of any bath nesessary for
preliminary treatment) and turning the pipe V over the vat B. There should be
enough liquor to cover the drum-Having transferred the liquor into the vat B, the
cocks are set so that the pump causes a circulation of the liquor through the drum-
This may be done in one of two ways. The liquor may be delivered by the pump to
vat B outside the drum and the interior of the latter put in communication with
the suction by pipe R (which may be provided with a downwardly directed con-
tinuation in the drum extending down near to the bottom of the interior of the drum
and not shown in the drawing). Or, the suction may be placed in direct communi-
cation by pipe Y with the bottom of the vat B and the delivery pipe of the pump
in connection with the pipe R-In this latter case the pipe V will serve as a safety
vent for the pipe T R should for any reason, as the filling of the drum, the flow
through the latter pipe be hindered.
During the process the drum should be kept in rotary motion, both to equalize
or compensate the varying pressure on and through the material to be dyed, and
also to prevent settlement of any precipitate there may be in the liquor on the
drum or matters held thereby.
Sheet 2 shows a slight modification in the shape of the holders E for adapting
them to hold forms of wound fibre without derangement such for instance as cops
and bobbins from bobbin and fly frame or other machines. The holders E are
divided into a number of compartments of shape necessary to exactly hold such
forms this being done by filling up space in the holders not wanted by suitable
solid filling, or by pressing out or making the holders in a number of circular
pits 5. 5. etc. Fig. 5 or pits of the shape desired, perforating only the floors of
such pits.
Since it is also in many instances advisable to dye, etc., with as small an amount
of liquor as is necessary. The interior of the drum may be provided with a water-
tight cylinder W occupying as much space therein as can be spared above that
necessary for proper circulation of the liquor. In the vat B there may also be
inserted blocks of wood or equivalents fillers 1. 2. 3. 4. (Fig. 3 Sheet 2) to bring the
interior of the vat to an approximately cylindrical shape.
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 ;-
'IN
ر
In apparatus for the treatment and dyeing of textile materials as set forth.
1). A drum the periphery of which is formed of or contains perforated compart-
ments adapted to receive and hold without derangement, roving, slivers, cops,
bobbins or any textile material more or less advanced in manufacture in the form
in which such material is provided, for the purpose set forth.
2). The combination of a vat, a rotary drum adapted to receive and hold without
derangement the material as set forth to be treated, a pump, and connections
whereby circulation of the liquor is set up through the pockets or compartments of
the said drum holding the material to be dyed or treated substantially as set
forth,

page_text: 3). The combination or construction of the vat and drum constructed for the
purposes set forth, with the fillers for the drum and unoccupied space of the vat
substantially as and for the purpose described.
