IMPROVEMENTS IN SIZING MACHINES
Year: 1883

page_text: LETTERS PATENT to Joseph Dugdale of the firm of Messieurs John Dugdale
and Sons Soho Foundry, Blackburn in the County of Lancaster for an
Invention of "IMPROVEMENTS IN SIZING MACHINES
"
PROVISIONAL SPECIFICATION left by the said Joseph Dugdale at the
Office of the Commissioners of Patents on the 22nd May 1883.
JOSEPH DUGDALE of the firm of Messieurs John Dugdale and Sons, Soho
Foundry Blackburn in the County of Lancaster. "IMPROVEMENTS IN SIZING
MACHINES
"
The objects of my Invention are, first, to add an improved slow motion to sizing
machines, when the belt is moved from the driving or fast pulley to the loose
pulley: second, an improved strap fork or guide: third, an arrangement for
levelling and crossing the yarn as it is being wound on the weavers beam and
also for pressing the yarn and fourth, the application of valves to regulate the
addmission of steam into the size box; this part of my Invention being also
applicable to other heating and boiling purposes when perforated pipes are
employed.
In applying the first part of my Invention to a sizing machine when one driving
(or fast) pulley and one loose pulley are employed I secure on the boss of the loose
pulley an eccentric or eccentrics with a strap or clip on its periphery secured to a
rod which is connected to and gives a vibrating motion to a lever or levers pivoted
on a stud or studs: this lever carries one or more pawls or catches which act on a
ratchet wheel or wheels keyed on the driving shaft of the machine: when the belt
is moved on to the loose pulley the eccentric gives a slow motion to the machine
by means of the lever, pawl and ratchet wheel
When the belt is moved on to the driving (or fast) pulley, a spring catch or
other suitable arrangement throws the pawl or pawls out of gear with the ratchet
wheel or wheels. In place of the ratchet wheel and pawl a friction wheel and
pawl or a combination of friction and ratchet wheels and pawls may be used.
The eccentric may be secured to the boss of a second or independent loose
pulley.

page_text: In my improved strap forks or guides for the belts on the cone drums or pulleys
I employ two worm shafts held in bearings on each side of the machine, one near
each cone drum or pulley: a strap fork or guide (for one or two belts) is secured
to each of the worm nuts and the worm nuts are connected and held in position
by a stay or rail. The worm shafts are connected by two pairs of mitre bevel
wheels and a shaft or by means of a chain and chain wheels or directly by wheels:
a handle or hand wheel may be fixed on either worm shaft by which the attendant
can regulate the position of the strap guides on each of the worm shafts by one
movement. Two racks sliding on rods or rails worked by rack wheels and
connected by suitable gearing may be used to actuate the strap forks or guides.
In performing that part of my Invention which relates to levelling and crossing
the yarn as it is being wound on the weavers beam. I form the leveller or presser
of any suitable shape and material and secure it to spring or rigid arms that are
pivoted on links secured in position by set screws or otherwise to a cross shaft or
rail: the arms (or a single arm) may be secured to the cross shaft or rail: a to and
fro' motion is given to this shaft in any convenient manner and a friction clip or
slip motion is used to connect the traverse motion to the shaft. The leveller is
shorter than the space between the warp beam flanges and it is caused to traverse
from one flange to the other by the arms which are secured to the traversing
shaft: the motion of this leveller causes the yarn to be levelled and crossed as it is
wound on the weavers beam.
'
The leveller or presser may be held fixed in the arms or the latter can be formed
so as to hold and yet allow the leveller or presser to revolve and thus present an
even surface to the yarn: one or more levellers or pressers may be used."
In carrying the last part of my Invention into effect I employ valves to regulate
the admission of steam from the pipes in the size box: at each or any of the
perforations or openings in the steam pipe I fix a valve, the stem of which may
cross the pipe; at one side the pipe is bored with a hole to form the valve seating
in which the valve rests and opposite a smaller hole is drilled in the pipe and
tapped to receive the end of the valve stem. The admission of steam can be
regulated by opening or closing the valve.
Ferrules or hoops may be secured to the pipes to hold the valves and the stem
in such case need not cross the opening in the pipe. Other adjustable valves and
their seatings can be fixed on the pipes. This part of my Invention can also be
applied to heating and boiling purposes when perforated pipes are used.

the said Joseph Dugdale in the Great Seal Patent Office on the 21st November
1883.
JOSEPH DUGDALE of the firm of Messieurs John Dugdale and Sons, Soho
Foundry, Blackburn in the County of Lancaster "IMPROVEMENTS IN SIZING
MACHINES
"
The objects of my Invention are first to add an improved slow motion to sizing
machines when the belt is moved from the driving or fast pulley to the loose
pulley. Secondly, an improved strap fork or guide. Thirdly, an arrangement for
levelling and crossing the yarn as it is being wound on the weavers beam and
also for pressing the yarn.
In applying the first part of my Invention to a sizing machine when one
driving (or fast) pulley and one loose pulley are employed, I secure on the boss
of the loose pulley an eccentric or eccentrics with a strap or clip on its periphery
secured to a rod which is connected to and gives a vibrating motion to a lever or
levers pivoted on a stud or studs: this lever carries one or more pawls or catches
which act on a ratchet wheel or wheels, keyed on the driving shaft of the
machine when the belt is moved on to the loose pulley the eccentric gives a
slow motion to the machine by means of the lever pawl and ratchet wheel.
When the belt is moved on to the driving (or fast) pulley a spring catch or
other suitable arrangement throws the pawl or pawls out of gear with the
ratchet wheel or wheels. In place of the ratchet wheel and pawl, a friction
wheel and pawl or a combination of friction and ratchet wheels and pawls may
be used.
The eccentric may be secured to the boss of a second or independent loose
pulley.
In my improved strap forks or guides for the belts on the cone drums or pulleys
I employ two worm shafts held in bearings on each side of the machine; one near
each cone drum or pulley: a strap fork or guide (for one or two belts) is secured
to each of the worm nuts and the worm nuts are connected and held in position
by a stay or rail. The worm shafts are connected by two pairs of mitre bevel
wheels and a shaft or by means of a chain and chain wheels or directly by wheels:
a handle or handwheel may be fixed on either worm shaft by which the attendant
can regulate the position of the strap guides on each of the worm shafts by one
movement. Two racks sliding on rods or rails worked by rack wheels and
connected by suitable gearing may be used to actuate the strap forks or guides
In performing that part of my Invention which relates to levelling and crossing
the yarn as it is being wound on the weavers beam, I form the leveller or presser
of any suitable shape and material and secure it to spring or rigid arms that are
pivoted on links secured in position by set screws or otherwise to a cross shaft or
rail the arms (or a single arm) may be secured to the cross shaft or rail: a to and
fro' motion is given to this shaft in any convenient manner and a friction clip or
slip motion is used to connect the traverse motion to the shaft.
:
The leveller is shorter than the space between the warp beam flanges and it is
caused to traverse from one flange to the other by the arms which are secured to:
the traversing shaft: the motion of this leveller causes the yarn to be levelled and
crossed as it is wound on the weavers beam.
The leveller or presser is held fixed in the arms and thus presents an even surface.
to the yarn. One or more levellers or pressers may be used.
And in order that my Invention may be fully understood and readily carried into

page_text: effect I will proceed to describe the accompanying two Sheets of drawings reference
being had to the figures and letters marked thereon.
Similar letters refer to similar parts throughout the several views.
Fig. 1 is a front end elevation. Fig. 2 a side view and Fig. 3 a plan of part of a
sizing machine to which my Improvements are applied.
In the drawings a is the driving shaft on which there are three pulleys a¹ a² a³
of which a is keyed' or secured to the shaft a and by which motion is com-
municated to the machine: a? is a loose pulley and a³ a pulley which runs loose
on the shaft a for giving the slow motion to the sizing machine when required:
to the boss of the pulley a³ is secured the spur pinion b which gears into the
wheel b secured to the stud 62: on this stud is a disc 63 with a radial slot on its
face one end of the lever c is secured by a bolt into the radial slot of the disc b³:
the other end of the lever c is pivoted or bolted to the lower end of the lever d
which is free to vibrate on the stud d¹: pawls d³ d' are pivoted to the lever d' and
engage or gear into ratchet teeth on part of the wheel e which is loose on the
shaft f: One portion of the ratchet wheel e is covered by a hollow wheel f¹ fast on
the shaft f: ratchet teeth are cut in opposite directions on the wheel e: the pawls f
secured in the wheel f¹ are free to fall on to those ratchet teeth on the wheel e
which are covered by it when the machine is running slowly.

The operation of the first part of my Invention is as follows:-When the belt
on the fast pulley a the machine is driven in the ordinary manner and the
pulley a³, gears
6 6 and the levers c and d and parts connected with them
remain stationary: in order to put the slow motion into gear, the driving belt is
moved from the fast pulley a' over the loose pulley a² and on to the pulley a³
which runs loose on the shaft a and has the spur pinion 6 secured to its boss: the
pinion b gears into and drives the wheel 61 secured to the shaft 62: the disc bª
actuates the lever c causes the lever d¹ to vibrate and the pawls d² d² gear in the
ratchet teeth on the loose wheel-e: the pawls f² resting also in the ratchet teeth of
the wheel e cause the wheel f¹ and the shaft f to revolve slowly.
When the belt is changed from the pulley as to the driving pulley a¹ the
machine runs at its full speed: the pulley a³ and spur gears 6 61 are stationary and
no motion is communicated to the levers c and d and pawls d²: the shaft fis
driven by a belt from the cone on the driving shaft a and the pawls f2fly outward
and do not touch the ratchet teeth on the wheel e till the machine stops or runs
sufficiently slowly.
I have shown the slow motion driven from a spur pinion on the boss of the
pulley a³ it is obvious that the motion might be communicated direct from the
pulley as by an. eccentric rod and pawls and ratchet wheel.
The second part of my Invention relates to the strap forks or guides for the belt
or belts on the cone drums and it is shown in Fig. 3 in which a' is the cone drum
secured to the driving shaft a: a belt a³ passes round this drum and the cone
drum f secured to the shaft f and gives motion to the latter when the machine is
driven by the pulley a'. The strap forks or guides g g¹ are secured to the worm
nuts h h the nut h has a thread on the inside and is screwed on the worm shaft i
and the nut h¹ is fitted in a similar manner to the worm shaft j-the nuts h h¹
are connected by a stay or rail h³. A hand wheel j' is secured to the worm shaft j
and a chain wheel is connected to another chain wheel i¹ of the same size on the
worm shaft i by a chain ³
:
The strap forks or guides h h' and the belt or belts a³ are moved in the following
manner-When it is necessary to drive the driven cone drum f³ and shaft f
quicker, the handwheel j is turned so as to move the nut h' and fork g' in the left
hand direction: the chain ³ gives a rotary motion to the worm shaft i which
causes the nut h and fork to move in the same direction and simultaneously
with the nut h¹ and fork g': the belt or belts a³ are thus drawn or caused to move
towards the larger diameter of the cone a* and the cone drum f³ is driven quicker.
To reduce the speed of the cone drum f³ it is only necessary to turn the hand-
wheel in the opposite direction .
C.

page_text: By this improved arrangement the attendant can regulate the position of the
strap guides on each worin shaft by one movement and both guides move without
any tendency to twist or stick.
In place of using the worm shafts i and j and nuts h h¹ racks, sliding on rods or
rails worked by rack wheels and connected by any suitable gearing may be used to
actuate the strap forks or guides h h¹. The worm shaft i may be driven from the
shaft j by two pairs of mitre bevel wheels and a short shaft or by spur gears
The third part of my Invention relates to levelling and crossing the yarn as it
is being wound on the weavers beam. I form the leveller or presser k of any
suitable shape and material and secure it to spring or rigid arms k¹ k¹ from which
a cross leveller k² is also suspended by links : the arms k¹ k' are pivoted on
links secured in position by thumb or set screws to the cross shaft or rail m to
which a to and fro motion is given in the following manner :-A revolving
shaft n has a worm n¹ secured to it which gears into and gives motion to the
worm o secured to the stud o': an eccentric o² carries a pin o³ which passes into a
slot p in the lever p which is free to vibrate on the stud p² in the frame of
the machine: the upper part of the lever is forked and takes on a pin q¹
fixed to a friction clip or boss q: a spring r rests upon the shaft m and is secured
to the clip q by a screw and thumb or winged nut r¹. This nut r¹ is always
screwed down to bear with sufficient pressure on the spring r so that the
vibrating motion of the lever p is transmitted by the pin q', clip q, and spring r to
give a to and fro motion to the shaft or rail m and thus to the leveller or presser k
which is shorter than the space between the beam flanges, and to the leveller or
yarn crosser k².
The traverse of the leveller k must be sufficient to work between the beam
flanges: the object of the slip motion is to allow the leveller k to yield when it
comes in contact with either flange of the beam and to remain in contact with
such flange for the desired time to level the yarn at the flanges before the traverse
is reversed: also to accomodate itself to slight variations of width between the
flanges. The arms k³ k¹ of the leveller or presser k and the cross leveller k² may
be either spring or rigid.
Each leveller or presser consists of a fixed rod tube or bar. The leveller k may
be weighted in any convenient manner when it is to be used as a presser.
By this improved arrangement I am able to level and cross the yarn as it is
being wound on the weavers beam of sizing machines in a more effective and simple
manner than has hitherto been accomplished.
Having stated the nature of my Invention and described the manner of
performing the same.
I declare that I claim
1.-The combination of the lever d, pawls d' ratchet wheel e with teeth cut in
opposite directions, the pawls f' and loose wheel f¹ substantially in the manner
and for the purposes shown and described.
2.-Two worm shafts and nuts or other equivalents with strap guides connected
by gearing for shifting a belt or belts on cone pulleys substantially in the manner
shown and described.
3. The leveller, presser or yarn crosser k with or without the cross leveller k³
fixed to spring or rigid arms traversed by a friction motion substantially in the
manner and for the purposes shown and described.
In witness whereof I the said Joseph Dugdale have hereunto set my hand and
seal this twentieth day of November One thousand eight hundred and eighty
three.
