In the Matter of Letters Patent granted to HENRY BERNOULLI
BARLOW, of Manchester, in the County of Lancaster, Patent
Agent, for the Invention of "IMPROVEMENTS IN MACHINES FOR
SIZING YARN," a communication from abroad by William
Lancaster, formerly of Cannstadt, in the Kingdom of Wurtem-
burg, bearing date at Westminster, the Eighteenth day of
January One thousand eight hundred and seventy, No. 145.
DISCLAIMER AND MEMORANDUM OF ALTERATION as proposed to
be entered, pursuant to the Statutes in that case made and provided,
by WILLIAM LANCASTER, formerly of Cannstadt, in the Kingdom
of Wurtemburg, but now residing at Accrington, in the County of
Lancaster, to whom the Letters Patent granted to the said Henry
Bernoulli Barlow have been assigned.

under the Great Seal of the United Kingdom of Great Britain and
Ireland, bearing date at Westminster, the Eighteenth day of January, in
the year of our Lord One thousand eight hundred and seventy, in the
thirty-third year of Her reign, did give and grant unto the said Henry
Bernoulli Barlow, his executors, administrators, and assigns, the sole
privilege of making, using, exercising, and vending the said Invention

And whereas in pursuance of a proviso in the said Letters Patent
contained, the said Henry Bernoulli Barlow, did within six calendar
months next after the date of the said Letters Patent, cause a Speci-
fication in writing, under his hand and seal, purporting to describe and
ascertain the nature of the said Invention, and in what manner the same
was to be performed, to be duly filed in the Great Seal Patent Office :
And whereas since filing the said Specification, it has been discovered
that in the part of the said Specification describing how the yarn is
carried forward to the warp beam, and contained in page 7, lines 12, 13,
14, of the Queen's Printers' copy of the said Specification, published in
One thousand eight hundred and seventy, it is erroneously stated that
the yarn is carried forward as usual to the warp beam r, whereas it is not
carried as usual but in the manner shewn in the Drawings annexed to
the said Specification, and particularly in Figures 4, 7, and I am therefore
the yarn passes in the ordinary manner around the drying cylinder k, and is carried forward as usual to the warp
.beam r which revolves in stationary bearings

NOW KNOW YE, that I, the said Henry Bernoulli Barlow, do hereby
declare the nature of the said Invention, and in what manner the same

page_text: is to be performed to be particularly described and ascertained in and
by the following statement, that is to say :-
The nature of this Invention consists in certain improved machinery
for applying the size equally and in sufficient quantity to the yarn and
for laying the projecting fibres, thereby adding to the strength of the
yarn, also for controlling and regulating the strength of the size in
accordance with the quantity of the fabric to be woven, also for winding
the yarn on the warp beam, and for working the machine slowly instead
of stopping it when changing the warp beam or for other purposes, and
for reducing the quantity of steam for boiling the size and for drying
the yarn.
And in order that the Invention may be fully understood and readily
carried into operation I will proceed to describe the two accompanying
Sheets of Drawings, reference being had to the figures and letters
marked thereon:
11.
1.
.
On Sheet 1, Fig. 1 is an elevation partly in section of part of a sizing
machine to which some of these improvements are applied. The yarn
as it is drawn off the ordinary warp beams, which are not shewn in the
Drawing, is taken over the back guide roller a, then over the roller b,
and under the roller c, this roller bears slightly upon the yarn as it
passes to the top roller d in the size box e.. To. the end of the back
guide roller a is fixed a worm gearing into the wheel a'. This wheel
is fixed on a short shaft on which is the worm a³ gearing into the
wheel on the end of the roller 6 which revolves in a trough con-
taining water or size or other suitable liquid to moisten the yarn and
to lay the projecting fibres before it enters the size trough: The
roller c revolves in segmental slots in the brackets c¹, and it is driven
at cach end by a pair of spur wheels, as shewn by dotted lines. The
top roller d bears upon the immersing roller f revolving in the size
box e, the object of this top, roller. is to keep the yarns in their proper
places when passing through the size box. The steam chest e¹ is
placed in the bottom of the size box e, and the upper part of this
steam chest is made with concave surfaces corresponding to the
peripheries of the immersing roller, f. and the finishing roller g, the
steam is taken through this steam chest before it passes to the drying
cylinders, thereby economising the steam. Before admitting the size
to the size box e it is boiled: or partially boiled in the steam-tight

page_text: '
:
vessel h, which is provided with the funnel and pipe to admit the
size and the pipe h² to supply the steam, also the pipe ³ to blow off the
air, and the pipe h' to convey the size to the size trough e. The tap h
placed between the vessel h; and the pipe * is a two-way tap, as
shewn full size in Fig: 2, one way is to let the boiled size flow into the
size box, and the other way is for letting off the water when it is
necessary to clean out the vessel h. The taps ho are to draw off samples
of the size while it is being boiled: By this apparatus the strength of
the size can be regulated according to the quantity of the yarn. After
the size has been applied to the yarn it is conveyed between the endless
belts of flannel or other material marked i and j, which act on each
side of the yarn as it passes from the size trough to the drying
cylinder to lay the fibres and to distribute the size evenly. These
belts pass over guide rollers and are kept clean by passing through the
troughs containing water or other liquid ¹ and ¹. These endless
belts are connected to staves of wood or other substance passing around
the toothed rollers 2 and j³. These toothed. rollers are turned slowly
round from the ordinary side shaft / by the level pinion gearing into
the wheel m¹ on the upright shaft m, to which are fixed the worms m³
and m³, each gearing into a spur wheel on the shafts of the toothed
rollers and. It is preferable to make the endless belts move in the
same direction as the yarn, but the direction and the speed at which
they move can be varied. After the yarn has passed beyond the endless
belts i and it is taken over and under the revolving lease rods n, n,
the object of which is to separate the warp threads. before they arrive
at the drying cylinder; these lease rods are turned slowly round in the
same or in contrary directions by the wheel 12 on the side shaft. gearing
into the wheel n² on the upright shaft n', on which are two worms n³,
each gearing into a wheel fixed on the axles of the lease rods n.
the yarn arrives at the drying cylinder it passes through the apparatus;
consisting of the wedges o, roller o!, and movable jacket or cover o²,
which is connected to the setting-on rod p to prevent the heat of the
drying cylinder from twisting the yarn when the machine is stopped.
While the drying cylinder is hot when the machine is at work the
roller of which revolves in open bearings fixed to the frame sides is held
above the yarn by the wedges o, as shewn in Fig. 3; but when the
machine is stopped the wedges slip from under the roller and allow it
to drop on the yarn, as shewn in Fig. 1, to hold the yarn against the
Before

page_text: jacket o. The wedges o are fixed to the jacket o³, which is provided
'with trunnions fitting in the upper end of the side leavers os mounted
on the fulcrum stud 0%. The lower end of one of the levers o³ has a stud
taking into the lever o mounted on the stud 0%, and the lower end of
the lever o enters between two set washers fixed on the setting-on
rod p, consequently as the rod p is moved to and fro to stop or start
the machine it moves the jacket and wedges in the manner above
described. This apparatus is chiefly useful for fine yarn. After the
yarn has been carried round the drying cylinder k it is wound on the
warp beam in the ordinary manner, or by the improved machinery
thereafter described.
ё
On Sheet 2, Fig. 4, is an elevation of a sizing machine to which certain
other parts of this Invention are applied. In this case the size box is
divided into two parts. In the part è containing the immersing roller
and the finishing roller g is a range or coil of pipes e³, through which
the size is forced, and in passing through these pipes the size is boiled or
partially boiled before it is discharged into the size box. After the yarn
leaves the size box e it is taken over a second finishing roller grevolving
in the trough e, in which is liquid tallow, grease, or other suitable com-
position for the purpose of giving strength and moisture to the yarn.
This trough is heated by a small flat steam pipe e* or otherwise.
The yarn having been thus sized and prepared passes on to the
smoothing apparatus i and j, which is a modification of that shewn in
Fig. 1.
In this instance the endless sheets of flannel or other soft
pliable material and j instead of being placed one above the other as
shewn in Fig. 1, are placed one in front of the other, and the .yarn after
passing over the sheet ; is taken under the sheet i, by which means both
sides of the yarn are operated upon. The sheets i and j pass between.
the rollers i² and j², which are turned slowly round by worms m² and m³
on the shaft m¹ as above described, and the sheets are kept clean by
passing through water or other liquid in the troughs and . The
shaft m¹ is driven by a worm on the side shaft gearing into a wheel on
the shaft m². The yarn then passes over and under the three rotating
lease rods n, n, n, which are turned slowly round by a toothed chain n
driven from the upper roller or other equivalent.
Between the last rod n and the drying cylinder k is the apparatus for
preventing the yarns twisting when the machine is stopped for removing

page_text: the finished beam or otherwise. This apparatus consists of a roller o'
and jacket o, as in the apparatus shewn in Fig. 1, but in this case the
roller o¹ is connected by a chain to the upright rod o', the lower end of
which passes through the lever o³ when the setting-on rod p is moved in
the direction of the arrow in Fig. 4, the stud p³ acting on the incline of
the lever o raises the shorter end thereof and depresses the longer end,
thus bringing down the rod o' and lifting the roller o¹ off the stationary
jacket o. The yarn passes in the ordinary manner-around the drying cylin
der-k, and is, in the manner shewn in the annexed Drawings in Figures 4,75
earried forward to the warp-beam, or which revolves in stationary-bearings.
Under the warp beam is the expanding roller shewn best in Fig. 5.
which represents an end view of the machine. This expanding roller is
made with segments fitting into each other and the ends of the roller s
enter between the flanges of the warp beam. The expanding. roller is
held up and pressed against the yarn as it is wound on the warp beam
by the weight t fixed to a strap passing partly round and attached to
the pulley on the shaft t, on which are two small pulleys (3, from
which depend two straps to which the trough is suspended. This
trough contains water or other fluid to damp the yarn as it is being
wound on the warp beam, the fluid being taken up by the two rollers t³,
and delivered by them to the surface of the expanding roller s. To the
pulley is also connected the weight to, the object of which is to
counterbalance the rollers and trough.
The last part of this Invention consists in the application of either a
worm or wheels for driving the roller by which the warp beam is driven
very slowly, when the attendant is taking out the full or finished yarn
beam or piccing up broken ends or for slight repairs which would other-
wise require the machine to be stopped. This machinery is shewn best
in Figs. 7, 8, and 9. On the driving shaft are placed three pulleys, the
fast pulley u on the outside, the loose pulley u' in the middle, and the
reducing pulley u³ in the inside. When the machine is to stand still the
driving strap must be thrown upon the middle pulley ; when the
machine has to go slowly the strap is on the pulley u²; on the boss of
this pulley is keyed a small pinion u³ driving a carrier wheel u', upon the
stud of which is a second pinion us driving a wheel v loose on the shaft
of the cylinder v¹. This wheel v is provided with an internal ratchet
wheel, as shewn in Figs. 8 and 9, and when set in motion by the

page_text: "
'
reducing pulley u² the ratchet teeth take hold of the inclined slide
or catch v², see Fig. 9, attached to the plate ³, which is fast to the
shaft v', by which means the said cylinder is driven at a very slow speed
during the time that the attendant is getting the machine in order or
taking out a weaver's beam, or for other purpose: By this arrangement
a slow positive regular speed is imparted to the warp beam through the
medium of the expanding drums, which acts as a driver to the warp
beam, and laps the yarn on at a regular positive speed. The ordinary
cone drums are also dispensed with.
Fig. 10 represents another modification of the apparatus for laying the
fibres and to distribute the size evenly on the yarn: w, w, are four reels
with eight arms and staves in each: Around the staves are sheets of
flannel or other pliable material marked i, i, and j, j. These reels arc
placed in pairs, and the yarn passes between them. The reels are
turned slowly round by gearing, and the staves of one pass in the spaces
between the staves of the other, or brushes may be put on the staves
and flannel in the spaces between them. The sheets or brushes are kept
clean by the cylindrical brushes x revolving in troughs and j¹.
the

I disclaim Figure 6 as represented in the annexed Drawings, in which
Figure the relative position of rollers is by mistake reversed, and in
which the course of the yarn is incorrectly indicated and the warp beam
is wrongly lettered p instead of being lettered r, as in Figures 4 and 5.
Having thus stated the nature of the Invention communicated to me
by the within-named William Lancaster, and described the manner of
performing the same, I declare that I claim,―
First. The application of a top roller to the immersing roller in the
size box to keep the yarns in their proper places while passing through
the size box.
Secondly. The apparatus for laying the fibres and distributing the size
evenly on the yarn, consisting of the endless belts i and j, or other
equivalents, as shewn and described in reference to Figs. 1, 4, and 10.
'
'
Thirdly. The apparatus, consisting of the roller o¹ and jacket o³,
and parts acting in combination therewith, as shewn and described in
reference to Figs. 1. and 4, to prevent the heat of the drying cylinder
from twisting the yarn when the machine is stopped.

page_text: Fourthly. The improved machinery, shewn in Figs. 4 and 5, for
applying pressure to the yarn while it is being wound on the warp
beam.
"
And, fifthly. The application of a worm and wheel or the machinery
shewn in Figs. 7, 8, and 9, for driving the roller by which the warp
beam is driven very slowly when the attendant is removing a full warp
beam, or for other purposes, instead of stopping the machine entirely,
as now customary.

page_text: LETTERS PATENT to Henry Bernoulli Barlow, of Manchester, in the
County of Lancaster, Patent Agent, for the Invention of "IM-
PROVEMENTS IN MACHINES FOR SIZING YARN."-A communication from
abroad by William Lancaster, of Cannstadt, in the Kingdom of
Wurtemburg.
Sealed the 12th July 1870, and dated the 18th January 1870.
PROVISIONAL SPECIFICATION left by the said Henry Bernoulli Barlow
at the Office of the Commissioners of Patents, with his Petition, on
the 18th January 1870.
I, HENRY BERNOULLI BARLOW, of Manchester, in the County of
Lancaster, Patent Agent, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINES FOR SIZING YARN," a communi-
cation to me from abroad by William Lancaster, of Cannstadt, in the
Kingdom of Wurtemburg, to be as follows:-
The object of these improvements is to apply the size equally and in
sufficient quantity to the yarn, and to lay the projecting fibres, thereby
ádding to the strength of the yarn; also to control and regulate the

page_text: strength of the size in accordance with the quality of the fabric to be
woven; also to facilitate the working of the machine, and to reduce the
quantity of steam for boiling the size and for drying the yarn.
These improvements consist, first, in applying a top roller to the
immersing roller in the size box, the object of which top roller is to keep
the yarns in their proper places when passing through the size box.
•
Secondly. In placing a steam chest in the bottom of the size box, and
in making the upper part of this steam chest with concave surfaces
corresponding to the peripheries of the immersing and finishing rollers.
The steam is taken through this steam chest before it passes to the drying
cylinders. Before admitting the size to the size box it is boiled in a
steam-tight vessel provided with pipes to admit the size and steam, to
blow off the air, and to convey the size to the size trough, also with
taps to draw off samples of the size.
Thirdly. In applying revolving brushes or endless belts of flannel or
other material to act on each side of the yarn as it passes from the size
trough to the drying cylinder to lay the fibres and to distribute the size
evenly. The brushes or belts are kept clean by passing through troughs
of water. When endless belts, one placed above the other, are used,
they are connected to staves of wood or other substance passing around
toothed rollers; but endless belts one in advance of the other may be
employed for the same purpose; or the yarn may pass between two
pairs of reels with staves surrounded by flannel, the staves of one recl
passing between the staves of the other reel. A brush or other
equivalent is used to keep the flannels clean.
Fourthly. In the application of revolving lease rods between the size
box and the drying cylinder to separate the yarns.
Fifthly. In the application of a wedge and roller and a movable jacket
connected to the setting on rod to prevent the heat of the drying
cylinder from twisting the yarn when the machine is stopped while the
drying cylinder is hot. When the machine is at work the roller is held
above the yarn by the wedges, but when the machine is stopped the
wedges slip from under the roller and 'allow it to drop on the yarn to hold
it against the jacket; or the roller may be lifted by an extra rod instead
of the wedges, and the jacket can then be stationary instead of movable.
Sixthly. In an expanding roller on which the warp beam rests; this
expanding roller is made with segments fitting into each other, and the

page_text: ends of the roller enter between the flanges of the warp beam. The
expanding roller is pressed against the yarn on the beam by weights
passing around a pulley on a shaft, and the warp is damped by rollers
revolving in a water trough under the expanding roller. One of the
weights is for counterbalancing the rollers and trough, and the other is
to give friction as the yarn beam increases in diameter.
Seventhly. In the application of a worm and wheel for driving the
warp beam very slowly when the attendant is piccing up broken ends
of yarn, the object of which is to prevent the entire stopping of the
machine, which would be injurious to the warp.
This Invention may be modified by making the size box in two parts,
and applying a coil of pipes in one part, through which the size is forced,
and in which the size is partly boiled before it is discharged into the
size box, also in taking the yarn after it has left the size box over a
roller revolving in a trough containing tallow, grease, or other com-
position, which is kept warm by a steam chest.
L
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Bernoulli Barlow in the Great Seal Patent
Office on the 16th July 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BERNOULLI BARLOW, of Manchester, in the County of Lancaster, Patent
Agent, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of January, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
third year of Her reign, did; for Herself, Her heirs and successors,
give and grant unto me, the said Henry Bernoulli Barlow, Her special
license that I, the said Henry Bernoulli Barlow, my executors, adminis-
trators, and assigns, or such others as I, the said Henry Bernoulli Barlow,
my exccutors, administrators, and assigns, should at any time agree with
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might, make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN MACHINES FOR SIZING YARN," a communication to me from abroad by

page_text: William Lancaster, of Cannstadt, in the Kingdom of Wurtemburg,
upon the condition (amongst others) that I, the said Henry Bernoulli
Barlow, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and scals, should particularly
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 I, the said Henry Bernoulli Barlow, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say) :-
The nature of this Invention consists in certain improved machinery
for applying the size equally and in sufficient quantity to the yarn, and
for laying the projecting fibres, thereby adding to the strength of the yarn;
also for controlling and regulating the strength of the size in accordance
with the quality of the fabric to be woven; also for winding the yarn on
the warp beam and for working the machine slowly instead of stopping it
when changing the warp beam or for other purposes, and for reducing
the quantity of steam for boiling the size and for drying the yarn.
And in order that the Invention may be fully understood and readily
carried into operation, I will proceed to describe the two accompanying
Sheets of Drawings, reference being had to the figures and letters marked
thereon..
On Sheet 1, Fig. 1 is an elevation partly in section of part of a sizing
machine to which some of these improvements are applied. The yarn
as it is drawn off the ordinary warp beams, which are not shown in the
Drawing, is taken over the back guide roller a, then over the roller b.
and under the roller c.; this roller bears slightly upon the yarn as it
passes to the top. roller. d in the size box e. To the end of the back;
guide roller a is fixed a worm gearing. into the wheel a¹.. . This wheel is
fixed on a short shaft on which is the worm a² gearing into the wheel on
the end of the roller.6, which revolves in a trough containing water or
size or other suitable liquid to moisten the yarn and to lay the projecting.
fibres before it enters, the size trough. The roller c revolves in segmental
slots in the brackets c¹, and it is driven at cach end by a pair of spur
wheels, as shewn by dotted lines. The top roller d bears upon the
immersing roller f revolving in the size box e; the object of this top

page_text: roller is to keep the yarns in their proper places when passing through
the size box. The steam chest e¹ is placed in the bottom of the size
box e, and the upper part of this steam chest is made with concave
surfaces corresponding to the peripheries of the immersing roller fand
the finishing roller g. The steam is taken through this steam chest
before it passes to the drying cylinders, thereby economising tlie steam.
Before admitting the size to the size box e it is boiled or partially boiled
in the steam-tight vessel ḥ, which is provided with the funnel and
pipe to admit the size, and the pipe h² to supply the steam, also the
pipe is to blow off the air, and the pipe /* to convey the size to the size
trough e. The tap placed between the vessel h and the pipe /* is a
two-way tap, as shewn full size in Fig. 2; one way is to let the boiled
size flow into the size box, and the other way is for letting off the water
when it is necessary to clean out the vessel h. The taps 6 are to draw
off samples of the size while it is being boiled. By this apparatus the
strength of the size can be regulated according to the quality of the
yarn. After the size has been applied to the yarn it is conveyed between
the endless belts of flannel or other material marked i and j, which act
on each side of the yarn as it passes from the. size trough to the drying
cylinder to lay the fibres and to distribute the size evenly. These
belts pass over guide rollers, and are kept clean by passing through the
troughs containing water or other liquid and j'. These endless belts
are connected to staves of wood or other substance passing around the
toothed rollers and j². These toothed rollers are turned slowly round
from the ordinary side shaft 7. by the bevel pinion gearing into the
wheel m¹ on the upright shaft m, to which are fixed the worms m²
and m³, cach gearing into a spur wheel on the shafts of the toothed
rollers and . It is preferable to make the endless belts move in the
same. direction as the yarn, but the direction and the speed at which
they move can be varied. After the yarn has passed beyond the endless
belts and j it is taken over and under the revolving lease rods n, n, the
abject of which is to separate the warp threads before they arrive at.
the drying cylinder; these lease rods are turned slowly round in the
same or in contrary directions by the wheel. 1 on the side shaft / gearing.
into the wheel n² on the upright shaft n³, on which are two worms n³,
cach gearing into a wheel fixed on the axles of the lease rods n.. Before
the yarn arrives at the drying cylinder it passes through the apparatus
consisting of the wedges o, roller o', and movable jacket or cover o³,
which is connected to the setting-on rod p to prevent the heat of the

page_text: drying cylinder from twisting the yarn when the machine is stopped
(while the drying cylinder is hot). When the machine is at work the
roller o¹, which revolves in open bearings fixed to the frame sides, is held
above the yarn by the wedges o, as shewn in Fig. 3, but when the
machine is stopped tlie wedges slip from under the roller and allow it to
drop on the yarn, as shown in Fig. 1, to hold the yarn against the
jacket o³. The wedges o are fixed to the jacket o³, which is provided
with trunnions fitting in the upper end of the side levers o³ mounted on
the fulcrum stud of. The lower end of one of the levers o³ has a stud
taking into the lever o mounted on the stud oº, and the lower end of the
lever o enters between two set washers fixed on the setting-on rod p,
consequently as the rod p. is moved to and fro to stop or start the
machine it moves the jacket and wedges in the manner above described.
This apparatus is chiefly useful for fine yarn. After the yarn has been
carried round the drying cylinder k it is wound on the warp beam in the
ordinary manner or by the improved machinery hereafter described.
On Sheet 2, Fig. 4 is an elevation of a sizing machine to which certain
other parts of this Invention are applied. In this case the size box is
divided into two parts. In the part e containing the immersing roller f
and the finishing roller g is a range or coil of pipes e³ through which the
size is forced, and in passing through these pipes the size is boiled or
partially boiled before it is discharged into the size box. After the yarn
leaves the size box e it is taken over a second finishing roller g¹ revolving
in the trough e, in which is liquid tallow, grease, or other suitable
composition for the purpose of giving strength and moisture to the yarn.
This trough is heated by a small flat steam pipe e³ or otherwise.
The yarn having been thus sized and prepared passes on to the
smoothing apparatus i and j, which is a modification of that shewn in
Fig. 1. In this instance the endless sheets of flannel or other soft
pliable material i and j, instead of being placed one above the other as
shewn in Fig. 1, are placed one in front of the other, and the yarn after
passing over the sheet j is taken under the sheet i, by which means both
sides of the yarn are operated upon. The sheets i and j pass between
the rollers and, which are turned slowly round by worms m² and m³
on the shaft m¹, as above described, and the sheets are kept clean by
passing through water or other liquid in the troughs and . The
shaft m' is driven by a worm on the side shaft 7 gearing into a wheel on
the shaft m'. The yarn then passes over and under the three rotating

driven from the upper roller i² or other equivalent.
Between the last rod n and the drying cylinder k is the apparatus for
preventing the yarns twisting when the machine is stopped for removing
the finished beam or otherwise. This apparatus consists of a roller o
and jacket o³, as in the apparatus shewn in Fig. 1, but in this case the
roller o¹ is connected by a chain to the upright rod o', the lower end of
which passes through the lever o³. When the setting-on rod p is moved
in the direction of the arrow in Fig. 4 the stud p³ acting on the incline
of the lever os raises the shorter end thereof and depresses the longer.
end, thus bringing down the rod o and lifting the roller o¹ off the
stationary jacket o². The yarn passes in the ordinary manner around'
the drying cylinder k, and is carried forward as usual to the warp
beam r, which revolves in stationary bearings. Under the warp beam is
the expanding roller s, shewn best in Fig. 5, which represents an end.
view of the machine. This expanding roller is made with segments
fitting into each other, and the ends of the roller s enter between
the flanges of the warp beam. The expanding roller is held up and
pressed against the yarn as it is wound on the warp beam by the
weight t fixed to a strap passing partly round and attached to the
pulley on the shaft t, on which are two small pulleys &³, from which
depend two straps to which the trough is suspended. This trough
contains water or other fluid to damp the yarn as it is being. wound on
the warp beam, the fluid being taken up by the two rollers and
delivered by them to the surface of the expanding roller s. To the
pulley is also connected the weight to, the object of which is to
counterbalance the rollers and trough.
The last part of this Invention consists in the application of either, a
worm or wheels for driving the roller, by which the warp beam is driven
very slowly when the attendant is taking out the full or finished yarn.
beam, or piccing up broken ends, or for slight repairs which would' other-
wise require the machine to be stopped. This machinery is shewn best
in Figs. 6, 7, 8, and 9. On the driving shaft are placed three pulleys;
tho fast pulley u on the outside, the loose pulley u¹ in the middle, and
the reducing pulley u² in the inside. When the machine is to stand.
still the driving strap must be thrown upon the middle pulley u¹; when
the machine has to go slowly the strap is on the pulley u². On the boss
of this pulley is keyed a small pinion w³ driving a carrier wheel u', 'upon.

shaft of the cylinder, o'. This wheel. v is provided with an internal
ratchet wheel, as shewn in Figs. 8 and 9, and when set in motion by the
reducing pulley 2 the ratchet teeth take hold of the inclined slide or

shaft v¹, by which means the said cylinder is driven at a very slow speed
during the time that the attendant is getting the machine in order,
or taking out a weaver's beam, or for other purpose. By this arrange-
mént a slow positive regular speed. is imparted to the warp beam
through the medium of the expanding drum s, which acts as a driver
to the warp beam and laps the yarn on at a regular positive speed. The
ordinary cone drums are also dispensed with.
Fig. 10 represents another modification of the apparatus for laying
the fibres and to distribute the size evenly on the yarn.
wo, w, are four
reels with eight arms and staves in each. Around the staves are sheets
of flannel or other pliable material marked i, i, and j, j. These reels are
placed in pairs, and the yarn passes between them. The reels are turned
slowly round by gearing, and the staves of one pass in the spaces
between the staves of the other; or brushes may be put on the staves
and flannel in the spaces between them. The sheets or brushes are kept
clean by the cylindrical brushes x revolving in troughs i¹ and j³.
Having thus stated the nature of the Invention communicated to me
by the within-named William Lancaster, and described the manner of
performing the same, I declare that I claim,-
First. The application of the trough and rollers acting in combination
therewith for damping the yarn and laying the fibres before the yarn
enters the size box.
Secondly. The application of a top roller to the immersing roller in
the size box to keep the yarns in their proper places while passing
through the size box.
Thirdly. The peculiar shape of the steam chest in the size box, as
shewn and described in reference to Fig. 1.
Fourthly. The improved apparatus shewn in Fig. 1 for boiling or
partially boiling the size before it enters the size box.
Fifthly. The application of melted tallow or other similar substance
to the yarn after it has passed through the size box, as shown and
described in reference.to Fig. 4.

page_text: Sixthly. The apparatus for laying the fibres and distributing the size
evenly on the yarn, consisting of the endless belts i and j, or other
equivalents, as shewn and described in reference to Figs. 1, 4, and 10.
Seventhly. The application of revolving lease rods between the size
box and the drying cylinder.
Eighthly. The apparatus consisting of the roller o¹, and jacket o³, and
parts acting in combination therewith, as shown and described in
reference to Figs. 1 and 4, to prevent the heat of the drying cylinder
from twisting the yarn when the machine is stopped.
Ninthly. The improved mode of constructing the expanding roller by
which the yarn is pressed on the warp beam, as shewn and described in
reference to Figs. 5 and 7.
Tenthly. The improved machinery shewn in Figs. 4 and 5 for applying
pressure to the yarn while it is being wound on the warp beam.
Eleventhly. The apparatus shewn in Figs. 4 and 5, or other equivalent
means, for damping the yarn while it is being wound on the warp beam.
And, twelfthly. The application of a worm and wheel, or the machinery.
shewn in Figs. 6, 7, 8, and 9,. for driving the roller by which the warp
beam is driven very slowly when the attendant is removing a full
warp beam, or for other purposes, instead of stopping the machine
entirely as now customary.
