page_text: LETTERS PATENT to John Dargue and William Dargue, of Bradford,
in the County of York, Machinists, for the Invention of “IMPROVE-
MENTS IN MACHINERY OR APPARATUS EMPLOYED IN THE PROCESS OF BLEACHING,
SCOURING, DYEING, AND SIZING WARPS, OR YARNS, AND FABRICS."
Sealed the 25th November 1870, and dated the 27th May 1870.
PROVISIONAL SPECIFICATION left by the said John Dargue and
William Dargue at the Office of the Commissioners of Patents,
with their Petition, on the 27th May 1870.
We, JOHN DARGUE and WILLIAM DARGUE, of Bradford, in the
County of York, Machinists, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN THE
PROCESS OF BLEACHING, SCOURING, DYEING, AND SIZING WARPS, OR YARNS, AND
FABRICE"
(to be as follows) :—
This Invention relates to machinery or apparatus employed in the
several processes of bleaching, scouring, dyeing, and sizing warps or
yarns and fabrics, in which machinery are a series of rollers arranged so

page_text: as to draw and conduct the said materials in a zig-zag direction through
the liquors, which are contained in suitable vessels; and the object of the
said Invention is to prevent breakage of the said warps, yarns, or fabrics
when any interruption or stoppage of a free passage takes place either by
entanglement or other cause of stoppage at the feed or supply end of the
machine and while the delivery end is in operation.
The improvements consist in arranging one of the bottom rollers in
slides so as to be capable of lifting or rising when extra tension or drag
is put upon the materials, and which by means of a finger or pin attached
thereto will actuate a lever connected to a slidable bar, on which is a
wedge or incline arranged to act upon a spring catch bar which is in
connection with a fork lever taking into the moveable driving part of a
friction box by which motion is given to the machine, so that on the
said roller being lifted the spring catch bar is liberated and the moveable
part of the friction box is placed out of contact with the other part,
whereby motion of the machine is immediately stopped, and thereby
breakage of warp, yarn, or fabric is prevented.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Dargue and William Dargue in the Great
Seal Patent Office on the 26th November 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, JoпN

describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Dargue and William Dargue,
do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement and accompanying two
Sheets of Drawings (that is to say):-
This Invention relates to machinery or apparatus employed in thọ
several processes of bleaching, scouring, dyeing, and sizing warps or
yarns and fabrics, in which machinery are a series of rollers arranged so
as to draw and conduct the said materials in a zig-zag direction through
the liquors which are contained in suitable vessels, and the object of the
said Invention is to prevent breakage of the said warps, yarns, or fabrics
when any interruption or stoppage of a free passage takes place either
by entanglement or other cause of stoppage at the feed or supply end of
the machine, and while the delivery end is in operation.
The improvements consist in arranging one of the bottom rollers. in
slides so as to be capable of lifting or rising when extra tension or drag
is put upon the materials, and which by means of a finger or pin
attached thereto will actuate a lever connected to a slidable bar on which
is a wedge or incline arranged to act upon a spring catch bar which
is in connection with a fork lever taking into the movable driving
part of a friction box, by which motion is given to the machine, so that
on the said roller being lifted the spring catch bar is liberated, and the
movable part of the friction box is placed out of contact with the other
part, whereby motion of the machine is immediately stopped, and thereby
breakage of warp, yarn, or fabric is prevented.
This Invention will be readily understoood by reference to the
accompanying Sheet of Drawings.

page_text: DESCRIPTION OF THE DRAWING
Fig. 1 represents the side elevation of a model machine constructed to
illustrate the machines used in the process of dyeing or other of the
herein-before named processes with our improvements applied thereto,
and Fig. 2 is part of a longitudinal section of the same.
In
These machines are composed of a vessel which is generally divided
into a series of compartments, as A and A¹, capable of containing or
holding the dye or other liquors required to be used in the process.
each compartment a series of rollers B are arranged on the top of the
vessel and another series C in the bottom to run in the liquor; also a
pair of squeezing rollers D. are usually applied to each compartment,
and which are geared together by a shaft E and bevil wheels F.
The method of using these machines in the several processes referred
to is by passing the warp or fabric over the first of the top rollers B
(see Fig. 2.), thence under the first of the bottom rollers C, thence over
the next top and under the next bottom roller, and so on with the
others in the series, and thence betwixt the squeezing rollers D, the
rotary motion of which in the proper direction draws the said warps
or fabrics through the liquor, and delivers the same to the rollers in the
next compartment, which conduct them to the next pair of squeezing
rollers and so on, the said yarns or fabrics passing through the series of
compartments and squeezing rollers simultaneously, as is well under-
stood by those conversant with dyeing or other of the above-named
processes.
Now in the practical use of these machines it is also well known that
if any impediment to the free passage of the yarns or fabrics occur, such
as getting entangled at the feeding or going-in end of the machine,
and the squeezing rollers continuing to draw the same forward damage
thereto necessarily ensues unless the machine can be readily stopped in
its motion. To prevent this damage therefore is the object of this our
Invention, and which we effect as follows:-We arrange one of the
bottom rollers C₁ so as to be capable of lifting or rising up by being
placed in the slides or grooves C³, and a pin or slide rod C³ rests on each
axis; also on each end of the axis or shaft of the top roller B we fix a
lever B³ to rest on the pins or slide rods C³, and on one end of the said
shaft we fix another lever G, to which a weight G is suspended; also on
the other end of said shaft is fixed a lever H, having a slot hole for a

page_text: stud I to enter and move in. This stud is fixed in a slide bar J, on
which is also fixed an incline or wedge K, which when put into motion
acts on a stud L fixed in another slide bar M, to which is attached a
spring N for pulling and holding it in that direction, and on the other
end is fixed a handle O, by which the attendant can pull it in that
direction opposed to the action of the spring, so that a notch P therein
will catch upon the bearing Q to hold it in that position. A stud R is
also fixed in this slide bar which takes into a slot hole in a lever S
hinged to the side of the machine at T, and the other end is formed into
a fork U, which clips into a groove formed on the movable part V of a
friction box or clutch box, the part V₁ of which is also a spur cog wheel
into which gears a spur pinion V² fixed on the shaft W, on which are
the driving pullies Y, by which motion is given to the machine. The
part V rides on a feather or key fixed in the shaft whilst the part VI
runs loose thereon.
It will be observed that when the friction box is in the position shewn
in these Drawings, no motion will be given to the rollers although the
shaft W may continue to rotate, but when the part V is pressed into
the recess of the part V₁ motion will be communicated to the said
rollers. Also that while the notch P of the slide bar M has hold on
the bearing Q the part V will be held in the position shewn. But it
will be evident that when the roller C¹ is lifted by the warp or fabrics
when being impeded in their free passage by entanglement or otherwise
the pins or slide rods C³ will act against and operate the levers B³, which
will in like manner actuate the lever H, whereby motion will be given
to the said slide bar J, forcing the incline or wedge K under the stud
pin L, by the action of which the slide bar M will be lifted when the
spring N will pull it in that direction, and by means of the lever S will
remove the part V out of the recess in the part V¹ of the friction box
and thereby instantly stop the motion of the rollers.
When the warps
or fabrics are rectified, the attendant by pulling at the handle O can
immediately set the rollers in motion, and the weight G³ pressing the
rods G upon the axis of the roller C¹ places it in its normal position
again.
It will now be evident to practical machinists that this method of
automatically stopping the squeezing or drawing rollers of such
machinery may be adapted to actuate the ordinary strap guides of
driving pullies in cases where friction boxes or clutch boxes are not

page_text: used, though the action thereon to produce stoppage will not be so
quick. It will be readily seen that instead of having one of the bottom
rollers moveable one of the top rollers may be moveable by being
supported on levers counterbalanced by either weights or springs, and
so as to be capable of being depressed or pressed down by the action of
the warps or fabrics when impeded or entangled, and by such depression
actuate by means of a similar arrangement of levers and slide bars
either friction box, clutch box, or strap guide to effect the stoppage. of
the said squeezing or drawing rollers.
Having thus fully described the nature of our said Invention and shewn
by Drawings in what manner the same is to be or may be performed,
or carried into practical operation, we would have it distinctly understood
that we do not confine ourselves to the precise details which we have
shewn and described, nor do we elaim any of the mechanism when
separately considered, but what we do claim as of our Invention and
believe to be new is, the method or means of automatically stopping the
rotation of the squeezing or drawing rollers D in such machinery by
having one or more of the carrying rollers B and C capable of lateral
movement when impediment or entanglement occurs, in manner sub-
stantially as shewn and described.
In witness whereof, I, the said John Dargue, for and on behalf of
myself and the said William Dargue, have hereunto set my hand
and seal, this Twenty-fourth day of November, in the year of
our Lord One thousand eight hundred and seventy.
