"Improvements in Machinery for Dyeing and Bleaching Yarns and
Fabrics.
We, JOHN CLAPHAM, of 19 St. Paul's Road, Bradford, in the County of
York, Stuff Merchant, WALTER WILLIAM LANCASTER LISHMAN, of Glen Dye
Works, Cornholme, Todmorden in the County aforesaid, Dyer, and MORDECAI
JEFFERSON, of Brown Royd Works, Bradford, in the County aforesaid, Machine
Maker, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in machinery or appliances employed in
the dyeing and bleaching of fabrics and yarns, the object being to facilitate such
operations, and to provide a ready means of withdrawing the yarns or fabric from
any one (or more) particular vat or tank without drawing off the liquor or contents,
also to provide appliances whereby the yarn or fabrics passing through vats can be
inspected or manipulated without drawing off the liquor or freeing the gases of the
tanks or vats, which are practically kept sealed. The invention also provides a
means for automatically taking up the yarns or fabrics intermittently or in unequal
lengths when desired.
According to this invention, we employ as series of vats or tanks placed side by
side, and in each tank or vat are the ordinary guide and immersion rollers, the
journals of which are mounted in frames carried and free to slide in vertical guides
or supports fixed to the vats or tanks. At or near the top of each vertical guide
is a pulley or block and hand wheel, and the pulley or block is, by chain or other
means, connected to the frame which carries the guide and immersion rollers, so that
by this means the frame and rollers can be moved up the vertical guides and above
the vats or tanks.
Over the tanks or vats, which contain liquors giving off gases or obnoxious
fumes, we arrange one, two, or more chambers in a manner somewhat similar to a
gasometer. The frame carrying the rollers is in this case provided with a bottom
tray nearly as large as the inside of the tank or vat, and the chamber next above
the tank or vat is open on its underside, and at its upper side has a funnel passing
to the interior of the second or top chamber. On the top of the funnel is a tray
closely fitting the interior of the top chamber, aud below the tray is a hole into the
funnel. When in the ordinary working position, the bottom tray, and immersion
and guide rollers are in the vat or tank, and the top guide rollers are in the first
chamber in which is the gas from the contents of the tank or vat.
When it is desired to examine or manipulate the fabric or yarns in the vat or
chamber, the first chamber is raised by pulley and chain or other means, and the
tray on the top of the funnel being thereby forced towards the top of the closed
top chamber, a vacuum is formed in the bottom of the latter, and the gas
of same, thus
is drawn up the funnel and through the hole near the top
transferring it from the second to the top chamber. When raising the first
chamber, and guide and immersion rollers, the bottom tray is also raised until
it comes to the top of the vat or tank, which it seals and prevents any further
escape of gas. It will thus be seen that in the act of raising the immersion and
guide rollers out of the tank or vat, the latter is automatically sealed, and the gas
is transferred from the first to the second or top chamber. When the chambers

page_text: are again lowered into the ordinary working position, the tray at the top of the
funnel forces the gas through the hole down the funnel into the first chamber which
is lowered onto the top of the vat, the bottom tray passing to the bottom of the
tank or vat, the liquor escaping around the edges between the tray and the tank,
the gases being recovered by means of a pump.
If it is desired to run one or more sets of take up or nip rollers intermittently so
as to leave the yarns or fabrics longer in any particular tank or vat, such rollers
are driven by bevel gear and clutch, the latter being controlled by fork and lever
operated by a cam on any driven shaft, so that by changing the throw of the cam,
the rollers are governed.

Improvements in Machinery for Dyeing and Bleaching Yarns and
Fabrics.
We, JOHN CLAPHAM, of 19 St. Paul's Road, Bradford, in the County of
York, Stuff Merchant, WALTER WILLIAM LANCASTER LISHMAN, of Glen Dye
Works, Cornholme, Todmorden, in the County aforesaid, Dyer, and MORDECAI
JEFFERSON, of Brown Royd Works, Bradford, in the County aforesaid, Machine
Maker, 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 relates to improvements in machinery or appliances employed in
the dyeing and bleaching of fabrics and yarns, the object being to facilitate such
operations, and to provide a ready means of withdrawing the yarus or labric from
any one (or more) particular vat or tank without drawing off the liquor or contents,
also to provide appliances whereby the yarns or fabrics passing through vats can
be inspected or manipulated without drawing off the liquor, or freeing the gases of
the tanks or vats, which are practically kept sealed. The invention also provides
a means for automatically taking up the yarns or fabrics intermittently or in
unequal lengths when desired.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which :-
Fig. 1 is a side elevation of so much of a dyeing machine as is required to
illustrate our invention, and shewing the method of raising the immersion rollers
and vat or tank covers.
Fig. 2 is a side elevation of part of a dyeing machine, shewing the improved
construction of vat or tank for containing liquids giving off gases or obnoxious
fumes.
Fig. 3 is an end elevation of part of a dyeing machine, shewing the improved
apparatus for intermittently driving "nip" or "take up" rollers.
According to this invention and referring to Fig. 1 of the drawings, we employ
a series of vats or tanks 1. 1 placed side by side, and in each tank or vat 1 are the
ordinary guide and immersion rollers 2. 2, the journals of which are mounted in
frames 3. 3 free to slide on the pair of vertical guide rods or supports 4. 4, which
are supported by the bearings 5. 5 fixed to the vats or tanks 1. 1.
At or near the
top of each pair or set of vertical guide rods 4. 4, and carried on a cross shaft or
frame 6, is a pulley or block 7 and hand wheel 8, and the pulley or block 7 is, by

page_text: chain 9, connected to the frame 3, which, carries the guide and immersion rollers 2.2,
so that by this means, the frame 3 and rollers 2 can be moved up the vertical
guides 4. 4, and above the vats or tanks 1. 1. The rollers 2. 2 may be mounted in
a frame 10, connected by vertical rods 11 to a cross bar 12, which by screw 13 can
be raised or lowered up or down the vertical guide rods 4. 4. The screw 13 is
driven by bevel wheels 14. 14 and hand wheel, chain, or other device.
Over the tanks or vats 1 which contain liquors giving off gases or obnoxious
fumes, we arrange one, two, or more chambers, in a manner somewhat similar to a
gasometer. The frame 3 carrying the rollers 2. 2 is in this case provided with a
bottom tray 16 nearly as large as the inside of the tank or vat 1, and the
chamber 17 next above the tank or vat 1 is open on its underside 18, and at its
upper side has a funnel 19 passing to the interior of the second or top chamber 20.
On the top of the funnel 19 is a tray 21, closely fitting the interior of the top
chamber 20, and below the tray 21 is a hole 22, into the funnel 19. When in the
ordinary working position, the bottom tray 16, and immersion and guide rollers 22
are in the vat or tank 1, and the top guide rollers 23 are in the first chamber 17,
in which is the gas from the contents of the tank or vat 1.
When it is desired to examine or manipulate the fabric or yarns in the vat or
chamber 1, the first chamber 17 is raised by pulley and chain or other means
hereinbefore described, and the tray 21 on the top of the funnel 19 being thereby
forced towards the top of the closed top chamber 20, a vacuum is formed in the
bottom of the latter, and the gas is drawn up the funuel 19, and through the
hole 22 near the top of same, thus transferring it from the second chamber 17 to
the top chamber 20. When raising the first chamber 17, and guide and immersion
rollers 2. 2, the bottom tray 16 is also raised until it comes to the top of the vat
or tank 1, which it seals by coming into contact with a projecting flange inside
the tank or vat 1, and thus prevents any further escape of gas. It will thus be
seen that in the act of raising the immersion and guide rollers 2. 2 out of the tank
or vat 1, the latter is automatically sealed, and the gas is transferred from the first
chamber 17 to the second or top chamber 20. When the chambers are again
lowered into the ordinary working position, the tray 21 at the top of the funnel 19
forces the gas through the hole 22 down the funnel 19 into the first chamber 17,
which is lowered onto the top of the vat 1, the bottom tray 16 passing to the
bottom of the tank or vat 1, the liquor escaping around the edges between the
tray 16 and the tank 1.
If it is desired to run one or more sets of take up or nip rollers 2. 2 intermittently,
so as to leave the yarns or fabrics longer in any particular tank or vat 1, such rollers
are driven by bevel gear 24 and clutch 25, the latter being controlled by fork 26
and lever 27 operated by a cam 28 (see Fig. 3) on any driven shaft 29, so that
by changing the throw of the cam 28, the rollers are governed, the clutch being in
or out of gear for a longer or shorter period according to the throw of the cam.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
(1.) The general construction, arrangement, and combination of parts con-
stituting the improved dyeing machinery, as and for the purpose herein described,
and substantially as illustrated by Fig. 1 of the accompanying drawings.
(2.) The method of and means employed for raising and lowering the guide
or immersion rollers of dyeing machinery, as and for the purpose herein described,
and substantially as illustrated by Fig. 1 of the annexed drawings.
(3.) The method of and means employed for raising and lowering guide or
immersion rollers of dyeing machinery, as and for the purpose herein described,
and substantially as illustrated by Fig. 2 of the annexed drawings.
(4.) A vat or tank 1 closed in the manner described, by the tray 16, and above
which is a second chamber open at its bottom side and closed at its top, the
funnel 19, tray 21, and chamber 20, all in combination, as and for the purpose

page_text: herein described, and substantially as illustrated by Fig. 2 of the accompanying
drawings.
