Albany, State of New York, United States of America.
1, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E. 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 has relation to apparatus for dyeing wool tops and it consists in
the improved construction and combination of parts of such an apparatus, in which
the tops may be placed around a perforated cylinder which is placed within a receptacle
or kettle and through which the dye liquor may be forced into the cylinder and through
the wool out into the kettle and thereupon back so that a perfect circulation of the dye
liquor through the wool may take place as hereinafter more fully described.
The accompanying drawing represents an elevation partly in section of this improved
apparatus for dyeing wool tops and the numeral 1 indicates the preparing kettle in
which the die liquor is prepared the said kettle having a suitable steam pipe 2 for the
purpose of heating the liquor and a pipe 3 extends from this kettle to the pump 5 and
suitable stop cock 4 being upon the said pipe for the purpose of cutting off the supply
from the preparing kettle.
A large tank 6 has bearings 7 at its ends in which the tubular trunnions 8 of a cylinder 9
of perforated metal or wire guaze are journalled the said trunnions being detachable
from the cylinder so that the cylinder may be removed and inserted into the tank while
the trunnions remain in their bearings.
One of the trunnions is provided with a pulley 10 to which suitable rotary motion is
imparted by any convenient means and the other trunnion is formed with two
pipes 11 and 12 entering it and provided with suitable stop cocks 13 and 14 and
connecting respectively with the inlet and discharge side of the pump.

page_text: Two similar pipes 15 and 16 having cocks 17 and 18 extend from the bottom of the
tank to the inlet and discharge end of the pump and the tank is provided with a steam
pipe 19 having a stop cock 20 through which pipe steam may be passed into the tank
heating the contents of the same.
The tops of which a few are shown at 21 placed upon the cylinder are wound around
the cylinder which has been removed from the tank for this purpose and the die liquor
is prepared in the preparing kettle.
When now the liquor is prepared and the tops are placed upon the cylinder the cock
of the pipe from the preparing kettle is opened and the pump is started pumping the
liquor from the preparing kettle into the cylinder through the hollow trunnion.
The liquor will thus be forced out through the perforated sides of the cylinder and
through the tops upon it, passing out into the tank where it will be heated by the
steam passing through the supply pipe.
While the liquor from the preparing kettle is pumped out the cock upon the inlet
pipe of the kettle is turned off and the inlet pipe from the bottom of the tank is
opened when the pump will continually circulate the liquor from the tank to the cylinder
and out through the tops.
For the purpose of subjecting the tops to an even exposure to the liquor from both
sides and the inlet pipe from the tank and the discharge pipe from the pump are closed
and the discharge pipe into the bottom of the tank and the supply pipe from the
trunnion are opened when the liquor will be pumped in at the bottom of the tank and
be drawn from the outside of the cylinder into the same passing again back to the tank
and so forth.
In this manner the tops will be perfectly subjected to the dye liquor and will be
thoroughly dyed and on account of their being wound upon the cylinder they may be
removed and dried in the same perfect state in which they were before dyeing so that
the tops and slivers of the tops may be worked as soon as dry instead of having to be
combed again and prepared before being worked.
This method and apparatus will therefore save time and labor in preparing the wool
and the dyeing may be done perfectly and thoroughly and the liquor will be forced
through the tops from both sides.
It follows that cotton and other fibrous material may be dyed in the same manner
as the wool tops.
Any form of pump may be used and any forms of distributing valves or cocks may
be used, so that instead of having four pipes extending to the tank and trunnions two
pipes may be used which will connect the said pipes with either end of the pump
may be employed-instead this arrangement simplifying the construction of the
apparatus.
7 am aware that revolving perforated cylinders, with material to be dyed placed thereon
have been used and that such perforated cylinders have been supported upon hollow
trunnions, through one of which the dye liquor has been fed to the cylinder, or has been
drawn through the same for circulation purposes. I am also aware that the dye liquor
has been previously prepared in a kettle and pumped therefrom into a tank used for
dyeing; therefore I make no claim to such apparatus in a broad sense and when used as
separate apparatus. But according to the present invention the dye liquor preparing
kettle, the dye tank, the revolving perforated cylinder hollow trunnions the supply and
discharge pipes, and the force pump are so arranged and combined as to constitute a
novel and practical invention by which the operation of dyeing wool tops and other fibrous
material can be carried into effect.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent and in what manner the
same is to be performed I declare that what I claim is :-
-
1. The improved method of dyeing tops consisting in winding the tops upon a
perforated cylinder and thereupon foreing the dye liquor through the side of the
eylinder and through the tops upon the same as and for the purpose shown and
set forth.

perforated cylinder for winding the tops upon and a pump for circulating the
dye liquor through the tank cylinder and tops as and for the purpose shown and
set forth.
3. An apparatus for dyeing tops consisting of a tank for holding dye liquor a
perforated cylinder for winding the tops upon and a pump having suitable connections
to the tank and to the-trunnion of the cylinder for alternately pumping the liquor
through the cylinder into the tank and back to the pump and vice versa as and for the
purpose shown and set forth.
-4In an apparatus for dyeing wool tops the combination of a preparing kettle having

for revolving it and secured detachably to the trunnions and a force pump having a
feed pipe from the preparing kettle and having two feed pipes and two discharge
pipes extending one of each respectively to the trunnion and to the tank and provided
with stop cocks as and for the purpose shown and set forth.

I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex, M.I.M.E.
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 has relation to apparatus for dyeing wool tops, and it consists in
the improved construction and combination of parts of such an apparatus, in which
the tops may be placed around a perforated cylinder which is placed within a receptacle
or kettle and through which the dye liquor may be forced into the cylinder and through
the wool out in the kettle and thereupon back so that a perfect circulation of the dye
liquor through the wool may take place as hereinafter more fully described.
The accompanying drawing represents an elevation partly in section of this improved
apparatus for dyeing wool tops and the numeral 1 indicates the preparing kettle in
which the die liquor is prepared the said kettle having a suitable steam pipe 2 for the
purpose of heating the liquor and a pipe 3 extends from this kettle to the pump 5 and
suitable stop cock being upon the said pipe for the purpose of cutting off the supply
from the preparing kettle.
A large tank 6 has bearings 7 at its ends in which the tubular trunnions 8 of a cylinder 9
of perforated metal or wire gauze are journalled the said trunnions being detachable
from the cylinder so that the cylinder may be removed and inserted into the tank while
the trunnions remain in their bearings.
One of the trunnions is provided with a pulley 10 to which suitable rotary motion is

page_text: imparted by any convenient means and the other trunnion is formed with two
pipes 11 and 12 entering it and provided with suitable stop cocks 13 and 14 and
connecting respectively with the inlet and discharge side of the pump.
Two similar pipes 15 and 16 having cocks 17 and 18 extend from the bottom of the
tank to the inlet and discharge end of the pump and the tank is provided with a steam
pipe 19 having a stop cock 20 through which pipe steam may be passed into the tank
heating the contents of the same.
The tops of which a few are shown at 21 placed upon the cylinder are wound round
the cylinder which has been removed from the tank for this purpose and the die liquor
is prepared in the preparing kettle.
When now the liquor is prepared and the tops are placed upon the cylinder the cock
of the pipe from the preparing kettle is opened and the pump is started pumping the
liquor from the preparing kettle into the cylinder through the hollow trunnions.
The liquor will thus be forced out through the perforated sides of the cylinder and
through the tops upon it, passing out into the tank where it will be heated by the
steam passing through the supply pipe.
While the liquor from the preparing kettle is pumped out the cock upon the inlet
pipe of the kettle is turned off and the inlet pipe from the bottom of the tank is
opened when the pump will continually circulate the liquor from the tank to the cylinder
and out through the tops.
For the purpose of subjecting the top to an even exposure to the liquor from both
sides and the inlet pipe from the tank and the discharge pipe from the pump are closed
and the discharge pipe into the bottom of the tank and the supply pipe from the
trunnion are opened when the liquor will be pumped in at the bottom of the tank and
be drawn from the outside of the cylinder into the same passing again back to the tank
and so forth.
In this manner the top will be perfectly subjected to the dye liquor and will be
thoroughly dyed and on account of their being wound upon the cylinder they may be
removed and dried in the same perfect state in which they were before dyeing so that
the tops and slivers of the tops may be worked as soon as dry instead of having to be
combed again and prepared before being worked.
This method and apparatus will therefore save time and labor in preparing the wool
and the dyeing may be done perfectly and thoroughly and the liquor will be forced
through the tops from both sides.
It follows that cotton and other fibrous material may be dyed in the same manner
as the wool tops.
Any form of pump may be used and any forms of distributing valves or cocks may
be used, so that instead of having four pipes extending to the tank and trunnions two
pipes may be used which will connect the said pipes with either end of the pump
may be employed instead this arrangement simplifying the construction of the
apparatus.

purpose shown and set forth.
4. In an apparatus for dyeing wool tops the combination of a preparing kettle having
means for heating it a tank having means for heating it and having bearings a
perforated cylinder having trunnions journalled in the bearings and having means
for revolving it and secured detachably to the trunnions and a force pump having
feed pipe from the preparing kettle and having two feed pipes and two discharge
