PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Dyeing and otherwise Treating Yarn
in Cop or similar form.
FREDERICK BARRACLOUGHI, formerly of Yeadon, but now of Cardigan Road,
Headingley, Leeds, Woollen Manufacturer, do hereby declare the nature of this
invention to be as follows:-.
This invention relates to apparatus such as that described in my Patent Specifi-
cation No. 14092 of A.D. 1894.
The object of my present invention is to increase the cop-capacity of such
apparatus without undesirably increasing the size of the treating tank and its
fittings.
In carrying out my invention, I construct an apparatus generally similar to that
described in my Patent Specification No. 14092 of A.D. 1894; except that I con-
struct it with two or any convenient larger number of treating tanks instead of
with one only, and I modify the covers of the treating tanks, and I alter the
delivery pipes, the air pipes, and the draining pipes to suit the increased number
of treating tanks.
I preferably arrange the treating tanks in a single or double row running
parallel with the front line of the two reservoirs; and I place them (the treating
tanks) all on one level with each other, with their bottoms above the tops of the
reservoirs.
The treating tanks are preferably rectangular in form, as described in my
above-mentioned Patent Specification; but do not necessarily confine myself
to this shape.
Instead of having a separate cover for each treating tank, I prefer to make
one large cover to cover two, more, or all of the treating tanks; so as to require the
smallest convenient number of covers for the whole set of treating tanks. The
cover or covers are counterpoised, as in my original invention.
In my present invention the internal arrangements and fittings of the treating
tanks preferably remain as described in my original Specification No. 14092 of A.D.
1894 but they may be modified if desirable, without affecting my present
invention.
I prefer to use only two delivery pipes, two air pipes, and two draining pipes
(one of each for each reservoir) as in my original apparatus, whatever the number
of treating tanks may be. But I arrange the upper ends of both delivery pipes
with any required number of horizontal branches, or branches and sub-branches:
and I connect one branch or sub-branch of each delivery pipe to each treating tank.
In my original Patent Specification No. 14092 of A.D. 1894, the air pipes of the
apparatus are shown and described as branches from the corresponding delivery
pipes instead of having independent connection with the treating tank and this
arrangement of the air pipes I preferably (but not necessarily) retain in my present
invention.
The points at which the air pipes join the respective delivery pipes are below the
points at which the branches of each delivery pipe go off to the various treating
tonke

my original specification, in order to get the largest number of cops into the

example, Fig. 1 in the drawings filed herewith, shows a four-tank apparatus in
which two covers a a are used, and each cover serves to close two tanks. The
cover or covers are counterpoised, as described in my former specification.
I prefer to use only two delivery pipes CC, two air pipes 11 D2, and two drain-
ing pipes n¹, 2, (one of each kind of pipe for each reservoir) as described in
my original specification,--whatever the number of treating tanks may be. But I
arrange the upper ends of both the delivery pipes with any required number of
horizontal branches, or branches and sub-branches, and I connect one branch or
sub-branch of each delivery pipe to each treating tank.
Different arrangements of these branches and branches and sub-branches
are shown in the drawings filed herewith, which will be more fully explained
further on.
In my original specification and drawings, the air pipes D1 D2 are described and
shown as branches from the corresponding delivery pipes C₁ C², instead of having
independent connection with the treating tank; and this arrangement of the air
pipes I retain in my present invention as shown in Figs. 1 and 4 of the drawings
filed herewith. Consequently the branches of the delivery pipes C³ C² are for all
practical purposes branches of the corresponding air-pipes also.
The air-pipes are provided with valves as shown and described in my original
drawings and specification.
When the treating tanks are arranged in a single row as shown in Figs. 1 and 2,
the draining pipes (marked ', in my original drawings) are in my present
invention branched at the upper end in a similar manner to the delivery pipe C³
Fig. 2 (to which I shall refer more fully later on),-one branch being connected to
each treating tank so that all the treating tanks can be drained simultaneously
into one or other of the two reservoirs. The draining pipe which discharges into
one reservoir is placed at the front of the row of treating tanks; and the draining
pipe which discharges into the other reservoir is placed at the back of the row of
treating tanks. The valve of each draining pipe is placed in the lower or un-
branched part of the pipe, so that it serves for all the branches..
Or as an alternative arrangement, I use one draining pipe oni, construct
it with branches at the upper end as just described, and also divide the lower enk
into two branches, one of which discharges into one reservoir and the other into the
other reservoir. In this case place no valve in the common, or unbranched, part
of the pipe, but I place a valve in each of the lower branches, so that the liquor
in the treating tanks may be drained into one reservoir or the other at pleasure.
When the treating tanks are arranged in a double row as shown in Figs. 3, 4,
and 5, I use only one draining pipe for all the tanks, and I divide it into two
branches (one discharging into each reservoir) at the lower end, as just described.
I also place a valve in each of these branches as just described. And at
the upper end of this draining pipe I make branches and sub-branches:
one branch leading to the front of the front row of treating tanks and the other
branch leading to the back of the back row of treating tanks, and the sub-branches
going off from these branches to each treating tank. The general arrangement
is the same as that of the branches and sub-branches of the delivery pipe C as
shown in Figs. 4 and 5, to which I shall refer more fully later on.
Owing to the branching of the upper end, or ends, of the draining pipe, or pipes,
being in all cases so similar to the branching of the delivery pipe C, (which is
fully illustrated in Figs. 2, 4, and 5 in the drawings filed herewith.)
I have not thought it necessary to file separate drawings of the draining pipes,

page_text: because the former is the simpler plan. But I prefer to use the spreading-cap
(preferably perforated) over the mouth of the pipe to distribute the current of
liquor in the treating tank, because otherwise the liquor might be forced more
strongly through some of the perforated cop tubes than others.
In working my improved apparatus, all the tanks are charged with cops in the
same manner as the single treating tank described in my original specification, and
the same valves are operated in the same manner, so that the circulation of the
dye-liquor is effected simultaneously in all the treating tanks, part of the liquor
passing through one treating tank and part through each of the others. (But the
liquor never passes from one treating tank to another.) The method of working
is in all essentials the same as the working of the apparatus described in my
original specification; and it admits of the same alternatives of pressure or suction
or combinations of the two.
Having described the general features of my present invention, I will now refer
in greater detail to some of the more important parts, with especial reference to the
five sheets of drawings filed herewith.
Figs. 1 and 2 are diagrams showing respectively a vertical and a horizontal
section of an arrangement of four treating tanks in a single row, with the necessary
delivery pipes and branches. The same arrangement of branches is suitable,
with alterations of a self-evident kind for any other number of treating tanks
arranged in a single row.
The section shown in Fig. 1 is made along the dotted line y y Fig. 2; and the
section shown in Fig. 2 is made along the dotted line, Fig. 1.
These diagrams show a convenient grouping of four treating tanks B BBB..
Each of the covers a serves to close two tanks, thus saving time and trouble'
in opening and closing the tanks. Fig. 1 also shows the arrangement of the
horizontal branches F F of the vertical delivery pipe C, and their connections with
the several treating tanks B B B B. It also shows part of the air-pipe D', corres-
ponding to the air-pipe D in. my original drawings.
In Fig. 2, B B B B are the same four treating tanks, C is the vertical
delivery pipe corresponding to the delivery pipe C in my original
drawings, and G & are the two horizontal branches of C, each
of which is connected to two of the treating tanks. (The air pipe D³
which is a branch of the delivery pipe C, as shown in my original drawings, is
not shown in this diagram.)
It is to be noted that in these two diagrams the delivery pipe C² is shown in
such a position that it must necessarily be exactly behind the delivery pipe C.
In order to bring it into this position, the form of delivery pipes shown in Fig. 1
of my original drawings is used; but the delivery pipe C is moved nearer to the
front of the apparatus, and the two reservoirs AA² are moved closer together
until C is exactly behind C.
But I do not necessarily confine myself to this particular method of grouping
four treating tanks. For example, I might group the four tanks in a square
instead of an oblong, that is, in two rows of two tanks each instead of one now of
four tanks.
But in all cases where the treating tanks are grouped in two rows, the arrange-
ment of the branches F F and Gas shown in Figs. 1 and 2 is impracticable;
and some form of the arrangement shown in Figs. 3, 4 and 5 is to be used instead.
Figs. 3, 4 and 5 show a convenient grouping of six treating tanks in two parallel
rows of three tanks each. They also show arrangements of the branches and sub-
branches of the delivery pipes C' and C2, with connections to each of the six
treating tanks. These arrangements of branches and sub-branches are applicable,
with suitable variations, to any other number of treating tanks (for eaxmple,
four, or eight), when they (the tanks) are arranged in two parallel rows; and
I do not confine myself to the number of tanks shown in the drawings.
Fig. 3 is a diagram showing a horizontal section through the horizontal branches
FF and sub-branches J J J J J J of the vertical delivery pipe C. The section

page_text: spindles) for the usual partition in each treating tank which I desire to throw
out of use. This blank partition is fitted with an upright rod corresponding to
the rod shown in my original drawings, and this rod is of such a length that
when the treating tank is closed, the cover a or the perforated plate (Fig. 2 in
my original drawings) just touches the top of it and thus holds the blank parti-
tion firmly down on its seat, thereby preventing any liquor circulating through
that tank. Consequently when the apparatus is working, all the liquor is forced
to pass through the other treating tanks.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:
In cop-dyeing apparatus such as that described and shown in my Patent Specifi-
cation No. 14092, of A.D. 1894,-
The combination of the two reservoirs and suitably modified delivery pipes
with a group of two or more treating tanks, in the manner described and shown
in my present specification.
