North Britain, Engineer, for the Invention of "IMPROVEMENTS IN MACHINERY
FOR WINDING, DOUBLING, AND TWISTING YARN OR THREAD."
PROVISIONAL SPECIFICATION left by the said John Boyd at the Office of
the Commissioners of Patents on the 17th June 1878.
JOHN BOYD, of Shettleston, in the County of Lanark, North Britain, Engineer.
"IMPROVEMENTS IN MACHINERY FOR WINDING, DOUBLING, AND TWISTING YARN
OR THREAD."
This Invention relates to various improvements in machines having the same
objects as some of those described in the Specification of Letters Patent granted to
the present applicant, and dated 13 November 1877 (No. 4241).
•
In an arrangement of combined winding and doubling machinery embodying
some of the present improvements, and which is also in part applicable for winding
single ends, the bobbin holder is fitted to slide vertically, being in the form of a
fork, having the bobbin between its prongs which work in vertical guides in fixed
brackets, whilst its shank passes through a guide above and carries at its upper
end a pulley or guide, over which the yarn ends or threads pass.
The detector details, which are by preference of one or other of the improved kinds
described in the earlier Specification herein-before referred to, are arranged partly
below the driving drum, and the yarn ends or threads pass up to the pulley at the
top of the holder shank, and thence downwards through the traverse guide to the
bobbin, so that the tension on the ends tends to increase the driving pressure
between the drum and bobbin. One prong or side of the holder has on its side a
stud, on which a hand lever centered on the bracket at that side can act for raising
the holder, and the acting part of this hand lever is curved so as to raise and let
down the holder gently, and is formed with a notch or recess, in which the stud of
1017

page_text: the holder engages when raised to its highest position. The bobbin spindle end
projects into slots in the holder at each side, these slots being shaped so that on
the holder being raised the spindle ends move a little outwards, and on the holder
attaining its highest position get upon shoulders at the top of the bracket guides
into positions admitting of the bobbin being conveniently removed by hand. A
fresh bobbin can then be inserted, and on the hand lever being turned over will be
guided down into the position for winding.
The pulley at the top of the bobbin holder shank may be made like the corre-
sponding pulley of former arrangements, or as is preferred in many cases; the
pulley may be a broad light pulley, consisting of end discs of wood or other
suitable material connected by wire or other pieces. This construction has amongst
its advantages that of keeping the ends separate from each other whilst availing of
the action of a stronger end in assisting a weaker one.
In an arrangement combining doubling, twisting, and winding, the detector
details are placed behind the feed rollers, and the lower roller is the driven one, the
upper roller being movable and carried by a bracket fixed to the upper end of a
vertical rod. The bracket has a catch plate fixed to it in a vertical position, or
Dearly so, which catch plato supports the counterpart catch plate of the main
detector lever, and the weight of that lever acting through the catch plates presses
the upper feed roller down in contact with the lower feed roller against the action
of a spring on the rod below. When an end or thread breaks or fails the bracket
carrying the upper roller is released from the downward pressure of the detector
lever, and is then raised by the spring, and at the same time an arm on the lower
part of the bracket rod shifts the driving cord to the loose pulley on the winding
spindle, which pulley is the upper one, whilst another arm presses up against the
fast pulley, which is the lower one, so as to stop the rotation of the spindle.
In an arrangement of machinery for winding yarn or thread on reels the reels are
not mounted on fixed spindles as in the arrangement described in the Specification
herein-before referred to, but are fixed on spindles, the outer ends of which are
supported during the winding operation by sliding brackets, which can be moved
down to admit of the removal of the banks or skeins.
The banks or skeins may be taken off a reel and hung on the end bracket, and
need not be removed from the bracket until several sets have accumulated thereon.
The reels are formed with six-armed centres or spoke pieces, four of the arms of
each centro being formed in one cross-shaped casting, and the other diametrical pair
of arins in a separate casting, which can be turned on the spindle in order to
slacken the yarn or thread after being wound, and to facilitate its being removed.
from the reel. Or three of the arms may be made in one casting, and the other.
three in another casting, or centres with other numbers of arms may be similarly
arranged.
The machine is made with a single central transverse vertical frame piece, and
the first-motion shaft is placed transversely, and has on it bevil wheels for driving
the reel spindles. The two reel spindles at either side of the machine are placed
sufficiently out of line with each other to prevent the several bevil wheels when of
equal sizes from interfering. Each reel spindle has on its inner end a collar, next
to which there is loose on it a bevil wheel in gear with that on the first-motion
shaft. Next to the bevil wheel there is on the reel spindle a disc having a worm
cut on its rim to work the counting details, and this disc also acts as a clutch,
being pressed towards the bevil wheel by a helical spring so as when free to act
to make the bevil wheel drive the spindle.
The motion of the reel is stopped by releasing the grip of the spring clutch
on the bevil wheel, which is effected by a small lever connected to a sliding
stopping bar or rod acted on by a spring, the small lever having a stud or
projection, which bears on the clutch disc so as to force it back and compress
the clutch spring.
The machine is provided with easily adjustable parts, allowing of any one of the
four reels which it carries winding according to any of the different modes most

page_text: commonly adopted; thus for hank or "cross" winding there is provided at each side of
the machine a short vertical shaft driven by bevil wheels from the first-motion shaft,
and having on its upper end an eccentric pin which causes a horizontal lever piece
to vibrate and impart the required traverse motion to the guide bars.
The vibrating lever pieces are connected to the several guide bars by separate
links, any one of which can be disconnected in the case of any reel being required
to wind differently. The links are by preference permanently jointed to the
vibrating levers, and when any one is disconnected from its traverse bar it is turned
into a recess formed for it in its lever, and retained therein by a pin. At each side
of the machine there is fixed at the middle of the length a broad vertical plate,
which is bolted to the longitudinal frames and to the central transverse frame, and
which whilst imparting the required rigidity to the structure serves conveniently
for carrying various details connected with the different modes of winding and
counting. Each of these vertical plates carries the two sets of details for the two
reels at one side of the machine; it will however be sufficient to describe one set.
A horizontal spindle carried partly by the plate has at its inner end the worm
wheel, acted on by the worm on the rim of the clutch disc on the reel spindle, and
one turn of this spindle corresponds to 80 or other suitable number of turns of the
reel. The spindle has on it a screw-grooved barrel, and a finger on a small block
fitted to slide on a square rod is acted on by the screw groove so as to cause the
stoppage of the reel at the end of any predetermined number of turns.
The square rod on which the finger block slides is fixed to a vertically sliding
piece, horein-after termed the rack piece, and which is arranged to throw the
stopping bar off its holding catch. The screw-grooved barrel carries a gauge piece,
which can be adjusted to suit any desired number of turns of the reel, and when
the reel is winding the finger block is moved outwards along its bar from the gauge.
picce as a starting point until it reaches au incline at the outer end of the barrel.
This incline causes the finger block to rise, and through the parts to which it is
connected to throw off the stopping bar.
The spindle of the screw-grooved barrel is carried near its inner end by a lever,
and it is fitted so that it can be moved sufficiently by means of the lever to take
the worm wheel out of gear from the worm on the reel spindle, and then a weighted
cord which was wound up during the previous action turns back the screw-grooved
barrel until the finger block reaches its starting point at the gauge piece.
"
The screw-grooved barrel is very conveniently applicable for determining the
quantities in hank or cross" winding, and it is also equally suitable for "skein "
winding and other varieties. The vertically moving rack piece, herein-before
referred to, is formed with the usual vertical series of rack teeth, to be acted on by
the single tooth on the end of the horizontal spindle, turned by the worm and worm
wheel from the reel spindle; and it also has at its upper end the usual series of
steps, by means of which the thread-guiding bar is moved when winding small skeins
in series, or what is known as "English 7 leas." The rack teeth are however formed
on one side of a vertical slot in the rack piece, and the slot extends above them so
that when the piece is sufficiently lowered the tooth on the end of the horizontal
spindle rotates without acting on the rack teeth. When the rack is in action the
piece is prevented from descending too low by an adjustable stop, but this stop is
adjusted to allow the rack teeth to descend lower for hank or " cross winding, or
other winding not requiring the rack-and-step action, and then an arm jointed to
the rack picce is turned up, its upper end reaching the stopping bar so as to act on
and lift that bar off its catch when the rack piece is raised by the action of the
screw-grooved barrel on the finger block, as herein-before described.
"
The arrangement of reeling apparatus, herein-before described, may be modified
so that reels may run on overhanging fixed spindles as in the arrangement described
in the earlier Specification herein-before referred to; also where a reeling machine
is required for only one kind of winding it may be made without such of the herein-
before described details as are only required for other kinds of winding.

page_text: In any case the recling machine is provided with detector inechanism for stopping
any one of the reels on the breakage or failure of any yarn end or thread that is
being wound on such reel, the detector mechanism being, by preference, of the
kind described. in the earlier Specification herein-before referred to.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Boyd in the Great Seal Patent Office on the 16th December
1878.
JOHN BOYD, of Shettleston, in the County of Lanark, North Britain, Engineer.
"IMPROVEMENTS IN MACHINERY FOR WINDING. DOUBLING, AND TWISTING YARN
OR THREAD."
.
My said Invention relates to various improvements in machines having the same
objects as some of those described in the Specification of Letters Patent granted to
mc, and dated 13 November 1877 (No. 4241).
And in order that my said invention, and the manner of performing the same,
may be most casily and properly understood I will at once proceed to describe the
various improvements comprised in it, with the aid of three Sheets of explanatory
Drawings which are hereunto appended, and which are herein-after referred to, tho
same reference numerals being used to mark the same or like parts wherever they
are repeated.
An arrangement of combined winding and doubling machinery embodying some
of my present improvements, and which is also in part applicable for winding singlo
ends, is shown in Figures 1, 2, and 3, on Sheet 1 of the accompanying Drawings.
Figure 1 is a front elevation; and Figure 2 is a vertical section, as at right angles
to Figure 1, these Figures however showing little more than the parts connected
with one winding drum, of which of course there may be any convenient number
in each complete machine or frame.
Figure 3 is a plan of a double-sided bracket 1 carrying guide levers 2, and which
is formed with a top plate 3 covering the outer ends of the levers 2, the outer edge
of the top plate 3 being notched, and the yarn or thread ends 4 being guided by
the notches and over the top plate 3 to the inner ends of the levers 2.
In the arrangement shown in Figures 1 and 2 the holder of the bobbin 5 is fitted
to slide vertically, being in the form of a fork, having the bobbin 5 between its
prongs 6, which work in vertical guides 7 in fixed brackets 8, whilst its shank 9
passes through a guide eye 10 above, and carries at its upper end a pulley 11 (or
it might be an ordinary thread guide) over which the yarn ends or threads 4 pass.
The detector details, which are by preference of one or other of the improved
kinds described in my earlier Specification, herein-before referred to, are arranged
partly below the driving drum 12, and the yarn ends, or threads 4 pass from the
inner ends of the guide levers 2 through the guide eyes or curls of the detector
levers 13, and thence up to the pulley 11 at the top of the bobbin-holder shank 9,
whence they return downwards through the traverse guide 14 to the bobbin 5, εO

page_text: that the tonsion on the ends tends to increase the driving pressure between the
drum 12 and bobbin 5. The use of the guide lovers 2 is to prevent slight irregu-
larities in the tension of each thread 4 from giving oscillating motions to the
detector levers 13; and for this purpose the guide levers 2 are weighted at their
outer ends, so that when a slackness occurs the inner end of the guido lever rises
and compensates for it. The inner end of each guide lever 2 is formed with prongs
turned upwards, between which the throad passes.
The arrangement of the detector details, shown in Figures 1 and 2, is the same
as that which in my earlier Specification, herein-before referred to, is described
with reference to Figure 10 of the Drawings accompanying that Specification.
One prong or side 6 of the bobbin holder has on its side a stud 15, on which a
hand lever 16 centered on the bracket 8 at that side can act for raising the holder;
and the acting part of this lever 16 is curved, so as to raise and let down the holder
gently, and is formed with a notch or recess 17, in which the stud 15 of the holder
engages when raised to its highest position. The ends of the bobbin spindle pro-
joct into slots in the side prongs 6 of the holder; theso slots, indicated by dotted
lines in Figure 2, being inclined or shaped, so that on the holder being raised the
spindle ends move a little outwards, and on the holder attaining its highest position
get upon shoulders at the tops of the guide brackets. 8 into positions admitting of
the bobbin being conveniently removed by hand. A fresh bobbin can then be
inserted, and on the hand lever 16 being turned over will be guided down into the
position for winding.
The pulley 11 at the top of the bobbin-holder shank 9 may be made, as shown
in Figures 1 and 2, like the corresponding pulley of my former arrangements; or,
as I prefer in many cases, it may be made as shown in front view in Figuro 4,
and in side view in Figure 5. As shown in these Figures the pulley consists of
thin end discs 18 of wood or other suitable material, connected by wire or other
pieces 19. This construction has amongst its advantages that of keeping the ends 4
separate from each other whilst availing of the action of a stronger end in assisting
a weaker one.
Figure 5 also shows a slight modification of the traverse guide 14, this modifica-
tion being of advantage with some yarns or threads. The guide 14 is formed with
an elongated hook or guiding part, so that whether the bobbin be full or empty the
ends 4 may pass down from the pulley above to the bobbin in a straight line or
plane as viewed sideways, that is, as in Figure 5. In this Figure there is also
shown a very simple, convenient, and easily adjusted frictional tension piece 20,
over which the ends 4 pass just before reaching the detector levers 13. This
piece 20 is a hollow metal cylinder resting in concave seats 21, and it has part of
its surface polished and part recessed, and covered with cloth or frictional material.
There is a separate piece 20 to each bobbin or set of ends, and it can be turned to
bring more or less of the cloth under the ends 4, and it can also be moved endways
to bring fresh surfaces under the ends.
An improved arrangement, combining doubling, twisting, and winding, is shown
in vertical section in Figure 6, and in it the detector details are placed behind or to
the inner side of the feed rollers 22, 23, and the lower roller 23 is the driven one,"
the upper roller 22 being movable, and carried by a bracket 24 fixed to the upper
end of a vertical rod 25. The bracket 24 has a catch plate 26 fixed to it in a
vertical position, or nearly so, which catch plate 26 supports the counterpart catch
plate of the main detector lever 27, and the weight of that lever acting through the
catch plate presses the upper feed roller 22 down in contact with the lower feed
roller 23 against the action of a spring 28 on the rod 25 below. When an end or
thread 4 breaks or fails the bracket 24, carrying the upper roller 22, is released
from the downward pressure of the main detector lever 27, and is then raised by
the spring 28, and at the same time an arın or prong 29 on the lower part of the
bracket rod 25 shifts the driving cord 30 to the loose pulley on the winding
spindle 31, which pulley is the upper one, whilst another arm 32, also fixed on the

page_text: rod 25, presses up against the fast pulley, which is the lower one, so as to stop the
rotation of the spindle 31.
Figure 7 is a plan, and Figure 8 is a vertical section of a modification of the
arrangement last herein-before described. In this modification the upper feed
roller 22 is carried by a two-armed roller 33, which has notches on its under side
at the outer ends of its arms, and is centered by such notches or pins fixed to two
brackets 34 fixed to the framing. The inner part of the holder 33 is over the rod 25,
on which rod in this case the catch plate 26 is fixed, and when the rod 25 rises it
lifts up the holder 33, and with it the roller 22.
*
Figure 9 is a vertical section showing a second modification of the same arrange-
ment, and in this modification the holder 33 of the upper roller 22 is centered on
pins on the brackets 34, which pins are at the inner side of the roller, whilst the
back of the holder is jointed to the top of the rod 25, which is arranged to act
reversely as compared with the previously described modifications. The spring (28)
is dispensed with, and the weight of the rod 25 makes it descend when its catch
plate 26 is released from that of the main detector lover 27. The top roller 22 is
then raised by the tilting of its holder 33, and at the same time the driving cord 30
is shifted to the loose pulley, which is the lower pulley in this case, whilst a pair
of levers 35, which serve to connect the lower part of the rod 25 to the framing,
press down two small brake blocks on the top of the upper or fast pulley.
An improved arrangement of machinery for winding yarn or thread on reels,
which is comprised in my present Invention, is shown on Sheets 2 and 3 of the
accompanying Drawings, Figure 10 being a sectional plan; Figure 11, a sectional
end elevation; and Figure 12, a sectional side elevation. The completo machine is
not shown, but only such parts as are required to show my present improvements.
In this arrangement the recls 41, 42, are not mounted on fixed spindles, as in the
arrangement described in my earlier Specification herein-before referred to, but are
fixed on spindles 43, the outer ends of which are supported during the winding
operation by sliding brackets 44, which can be moved down to admit of the removal
of the banks or skeins.
The hanks or skeins may be taken off a recl and hung on the fixed end bracket
45, by which the movable bracket 44 is carried, and need not be removed thence
until several sets have accumulated. A handle 46 fixed to the movable bracket 44
projects through a slot in the fixed bracket 45, and serves for raising and lowering
the foriner, which when raised has its bottom end resting on a catch. The socket
in the fixed bracket 45 is made wide enough to allow of as much lateral movement
of the bottom of the moveable bracket 44 as is required for putting it on or off
the catch. The reels 41, 42, are formed with six-armed centres or spoke pieces,
four 41 of the arms of each centre being formed in one cross-shaped casting, and
the other diametrical pair 42 of arms in a separate casting, which can be turned
on the spindle 43 in order to slacken the yarn or thread after being wound, and to
facilitate its being removed from the reel; or three of the arms may be made in
one casting, and the other three in another casting; or centres with other numbers
of arms may be similarly arranged.
The machine is made with a single central transverse vertical frame piece 47,
which is fixed at its ends to the middles of upper and lower longitudinal rails 48, 49,
and these rails are at their ends fixed to end frames 50. The first motion shaft 51
is placed transversely, being carried by the central frame piece 47, and it has on
it bovil wheels 52 for driving four reels (two of these bevil wheels 52 being shown
in Figure 10). The shaft 51 also, by bevil wheels, drives the cam shafts 28' of the
detector details. The reel spindles 43 are carried by bearing brackets 70 fixed to
the frame piece 47, the two spindles at one side of the machine being placed
sufficiently out of line with each other to prevent the several bevil wheels 52, 53,
when of equal sizes, from interfering. Each reel spindle 43 has on its inner end
à collar, next to which there is loose on it a bevil wheel 53 in gear with that 52 on
the first motion shaft 51. Next to the bovil wheel 53 there is on the reel spindle

page_text: a disc 54, having a worm cut on its rim to work the counting details; and this
disc 54 also acts as a clutch, being pressed towards the bevil wheel 53 by a helical
spring 55, so as, when free, to act to make the bevil wheel 53 drive the spindle 43,
with which last the clutch 54 is engaged by means of a groove and key.
•
The motion of the reel is stopped by relieving the grip of the spring clutch 54
on the bevil wheel 53, which is effected by a small lever 56 connected to a sliding
stopping bar 57 acted on by a spring 58, the small lever 56 having a stud or pro-
jection which bears on the disc 54, so as to force it back and compress the clutch
spring 55.
The machine is provided with easily adjustable parts, allowing of any one of the
four reels which it carries winding according to any of the different modes most
commonly adopted. Thus, for "cross" reeling there is provided at each side of
the machine a short vertical shaft 59 driven by bevil wheels 60, from the first
motion shaft 51, and having at its upper end an eccentric pin 61, which causes a
slotted horizontal lever pieco 02 to vibrate and impart the required traverse motion
to the guide bars 63. Each vibrating lever piece 62 is connected to the guide
bars 63 by separato links 64, any one of which can be disconnected in the case of
any reel being required to wind differently.
The links 64 are by preferonco permanently jointed to the vibrating lever picce
62, and when any one is disconnected from its traverse bar 63 it is turned into a
recess formed for it in its lever piece, and retained therein by a pin.
At each side of the machine there is fixed at the middle of the length a broad
vertical plate 65, which is bolted to the longitudinal rails 48, 49, and to the centrul
transverse frame 47, and which whilst imparting the required rigidity to the
structure serves conveniently for carrying various details connectod with the
different modes of winding and counting. Each of these vertical plates 65 carries
the two sets of details for the two reels at one side of the machine; it will however
be sufficient to describe one set.
A horizontal spindle 66, carried partly by the plate 65, has at its inner end the
worm wheel 67 (indicated by dotted lines behind the brackets 44, 45, in Figure 11),
acted on by the worm on the rim of the clutch disc 54, on the reel spindle 43, and
one turn of this spindle 66 corresponds to 80 or other suitable number of turns of
the reel. The spindle 66 has on it a screw-grooved barrel 68, and a finger 69 on a
small block fitted to slide on a square rod 70, is acted on by the screw groove, so
as to cause the stoppage of the reel at the end of any predetermined number of
turns.
The square rod 70, upon which the finger block 69 slides, is fixed to a vertically
sliding piece 71, herein-after terined the rack piece, and which is arranged to throw
the stopping bar 57 off its holding catch. The screw-grooved barrel 68 carries a gauge
piece 72, which can be adjusted to suit any desired number of turns of the reel, and
when the reel is winding, the finger block 69 is moved outwards along its bar 70,
from the gauge pieco 72, as a starting point until it reaches an incline at the outer
end of the barrel 68. This incline causes a finger block 69 to rise, and through the
parts to which it is connected to throw off the stopping bar 57.
The spindle 66 of the screw-grooved barrel 68 is carried near its inner end by a
lever 73, and it is fitted so that it can be moved sufficiently by means of the lever 73
to take the worn wheel out of gear from the worm on the disc 54, and then a
weighted cord 74, which was wound up during the previous actions, turns back the
screw-grooved barrel 68 until the finger block 69 reaches its starting point at the
guage piece 72.
#
The screw-grooved barrel 68 is very conveniently applicable for determining the
quantities in hank or cross" winding, aud it is also equally suitable for "skein "
winding and other varieties. The vertically moving rack piece 71 is formed with
the usual vertical series of rack teeth 75, to be acted on by the single tooth on the
end of the horizontal spindle 66, turned by the worm and worm wheel from the reel
spindle, and it also has at its upper end. the usual series of steps 76 (indicated. by

page_text: dotted lines in Figure 12), by means of which the thread guiding bar 63 is moved
when winding sinall skeins in series, or what is known as "English 7 leas."
In Figure 12 this last-named style of winding is shown at a part of the machine
to the right of the centre, whilst "cross" winding is shown at a part to the left,
and in the Intter case the doubling or combining together of two yarns or threads 4
is shown as combined with hank winding, a process which may in some cases be
conveniently substituted for doubling combined with winding upon bobbins. The
vertical rack teeth 75 are formed (somewhat differently from what has been usual)
on one side of a vertical slot in the rack piece 71, and the slot extends above them,
so that when the piece is sufficiently lowered the tooth on the end of the horizontal
spindle 66 rotates without acting on the rack teeth 75. When the rack 75 is in
action, the piece 71 is prevented from descending too low by an adjustable stop 77,
but this stop is adjusted to allow the rack piece 71 to descend lower for hank or
cross" winding, or other winding not requiring the rack and step action, and then
an arm 78, jointed to the rack piece 71 is turned up, its upper end reaching the
stopping bar 57, so as to act on and lift that bar off its catch, when the rack
piece 71 is raised by the action of the screw-grooved barrel 68 on the finger block 69,
as herein-before described.
#
My arrangement of reeling apparatus herein-before described may be modified so
that the reels may run on overhanging fixed spindles, as in the arrangement described
in my earlier Specification herein-before referred to.
Also, where a recling machine is required for only one kind of winding, it may bo
made without such of the herein-before described details as are only required for
other kinds of winding.
In any case the reeling machine is by preference provided with detector mechanism
for stopping any one of the reels on breakage or failure of any yarn or thread end
that is being wound on such reel, the detector mechanism being by preference of the
kind described in my earlier Specification herein-before referred to.
Having thus particularly described my said Invention and the manner of per-
forming the same, I have to state that I do not restrict myself to the precise
details herein described or delineated, but that what I believe to be novel and original,
and claim as the Invention secured to me by and in terms of the herein-before in
part recited Letters Patent is,—
