County of Lancaster, Machinist, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR WINDING YARN OR THREAD ON TO BOBBINS, SPOOLS, OR OTHER
SIMILAR SURFACES"
Sealed the 12th September 1860, and dated the 16th March 1860.
PROVISIONAL SPECIFICATION left by the said William Weild at the
Office of the Commissioners of Patents, with his Petition, on the
16th March 1860.
1
I, WILLIAM WEILD, of the City of Manchester, in the County of Lancaster,
Machinist, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY FOR WINDING YARN OR THREAD ON TO BOBBINS, SPOOLS, OR
OTHER SIMILAR SURFACES," to be as follows:-
My improvements are made upon machinery for the purpose above named,
for which a Patent was granted to me, numbered 122, and dated the Twenty-
second day of January, in the year of our Lord One thousand eight hundred
and fifty-eight.
The first part of my improvements applies principally to the machinery
illustrated in the Drawings accompanying the Specification of my aforesaid
Patent by the Figures on Sheets 1 to 14, both inclusive, and consists of the
following modifications of such machinery :-
First, in a new arrangement of the countershaft and apparatus connected.

page_text: therewith, by which the machine receives motion. The countershaft is placed
in bearings on the framing, and passes from one end of the machine to the
other. The stopping and starting rod is placed in front of the machine, and is
connected with a vertical shaft, on which the belt guide is fixed. The cone
drums for diminishing the speed of the machine as the spools increase in
diameter, are placed on the framing of the machine, and are connected with
mechanism for traversing the belt on the cone drums; this mechanism consists
of a peculiarly arranged cam, partly rotated by the first motion shaft, and
partly by the cam shaft which effects the changes of the spools.
Secondly, the application of a brake to the pulley on which the belt works
when giving motion to the cam shaft, which effects the changes of the spools,
which brake arrests the motion of that shaft without shock, and is actuated by
a cam on the belt changing cam shaft (64) this arrangement being a substitute
for the click which catches in a notch on a disc (7) on the spool changing
cam shaft (m).
Thirdly, a new arrangement of the cam and parts actuating the brake (10)
for stopping the winding so as to bring the brake into action before the thread
guides are lifted from the spools, and in securing one of the driving wheels on
its shaft by friction, or a screw nut arranged so that in case of obstruction
this friction arrangement will give way, or the nut will become unscrewed.
Fourthly, a new arrangement of the mechanism rotating the cam shaft for
advancing "the shaper, which consists of a series of compound levers.
Fifthly, in providing a screw adjustment to the fulcrum of the ".
plate lever," (which is connected with the shaper,) so that it may be regulated
with the greatest nicety.
escape
Sixthly, in a simplified arrangement of the mechanism transmitting motion
to the thread guides, by which one of the two shafts and cams described for
this purpose in my aforesaid Specification is dispensed with.
Seventhly, a new shape and construction of the cradle piece (gl), which is
no longer used for sustaining the spool while it is being placed on the spindle
and an improved shape and arrangement of cams for actuating the spindles,
this alteration being consequent upon dispensing with the cradle as a support,
and the improved mode of feeding the empty spools next herein-after
mentioned.
Eighthly, a new arrangement of the ram which feeds the empty spools,
which ram is made, by means of a spring applied thereto, to carry the empty
spool, and hold it opposite the spindle, the said spring giving way to allow
the ram to be drawn back, and thus get clear of the bobbin when placed on
the spindle.

page_text: Ninthly, the application of a V-piece of thin metal to the side of the
feeding ram, which assists to place the thread in its correct position.
Tenthly, the actuation of the thread presser (220) independently of the
feeding ram by a separate cam.
Eleventhly, using instead of the brush (d) for putting friction on the
thread a pair of spring fingers, the surfaces coming in contact with the
thread, being steel pieces arranged so as to be readily replaced when worn
out, the amount of friction being adjustable by a screw.
Twelfthly, in the Specification of my aforesaid Patent the Figures on
Sheets 16, 17, and 18, illustrate what I term the single-bobbin machine, while
that machine which I have herein- before referred to I term the double-bobbin
machine; and this part of my present Invention relates to arrangements by
which some of the pecularities of the single-bobbin machine are imported in
a modified form into and combined with the mechanism of the double-bobbin
machine, in such manner as to change it into a single-bobbin machine,
applicable to the winding of thread upon spools of different sizes. The
proposed modifications and improvements in which this part of my Invention
consists will be understood by comparing the following description of the new
mode of action of the machine, as improved with the modes of action of the
double and single-bobbin machines as described in my aforesaid Specifiation.
The thread is wound upon the spool as in the double-bobbin machine, and the
thread guides rises as in that machine when the spool is full; then a knife
carried by an arm on a shaft, actuated by a cam, makes an incision into the
end of the spool, and then lifts itself out of the way, but leaves against the
spool a spring point, also carried by the said arm which serves to guide the
thread into the incision made in the head of spool. While this is taking
place a finger, placed on a rod corresponding to that which actuates the
cradles in the double-bobbin machine, comes between the thread guide and
the said spring point, and takes the thread past the head of the spool
sufficiently to enable a hook (connected with a shaft actuated by a cain) to
catch hold of it. This hook pulls the thread in such direction as to draw it
into the incision formed in the head of the spool; the hook also by the same
movement draws the thread against a fixed spring on one side and a fixed
edge on the other side of the hook; by this means the thread is cut by the
said edge, and the end of the thread is held fast between the fixed spring and
the side of the hook, and by the time the hook has completed its movement
the said finger has begun to retire out of the way, the spindle in the spool is
withdrawn, and the spool drops out of the way; about the same time a feeding
arrangement allows an empty spool to drop into a fixed cradle piece, and a

page_text: hollow tube (corresponding to the second spindle in the double bobbin machine
which tube has been previously withdrawn by the action of a cam) then
advances and forces the empty spool on to the rotating spindle which has
been previously brought back to its first position after delivering the full
spool on to the board in front of the machine. The line of the thread between
the thread guide and the hook and holding spring is such that when the
spindle is withdrawn and the full spool delivered, the thread will be caught
between the end of the empty spool when forced on the spindle and a
shoulder upon the spindle against which the spool is forced, and thus the
end of the thread will be securely held, so as to wind on to the empty spool,
the end of the thread being released from between the said pinching spring
and the side of the hook by a back movement of the hook just previously
to the machine beginning to wind. The apparatus for feeding the empty
spools in this machine consists of a surface just above the fixed cradle,
from which the empty spool is pushed on to the spindle; the spools are
placed on this surface one at a time, and the withdrawing of the surface
by cam action allows them one by one to fall into the cradle after the tube
has been drawn back which forces the spool on to the spindle.
Thirteenthly, another improvement applicable to any of my patented
machines for winding thread relates to means for giving a polish to the last
layers of thread on the spool when the thread has not been previously
polished, and consists in an arrangement or arrangements of rollers or
other surfaces capable of taking up moisture, which when moistened are
brought at the required time in contact with the passing thread by cam
action or other self-acting meaus. This moisture, when imparted to the
thread by the rollers or other surfaces, and thereby brought into contact
with the heat evolved by the thread guide (which becomes hot by friction
on the spool), produces the polish required.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Weild in the Great Seal Patent Office on the
15th September 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WEILD, of the City of Manchester, in the County of Lancaster, Machinist,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of March, in the year of our

page_text: Lord One thousand eight hundred and sixty, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said William Weild, Her special license that I, the said
William Weild, my executors, administrators, and assigns, or such others
as 1, the said William Weild, my executors, 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

Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN MACHINERY FOR WINDING YARN OR THREAD ON TO
BOBBINS. SPOOLS, OR OTHER SIMILAR SURFACES," upon the condition (amongst
others) that I, the said William Weild, by an instrument in writing under
my hand and seal, 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 William Weild, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings, that is to say :—
My improvements are made upon machinery for the purpose above-named,
for which a Patent was granted to me, No. 122, and dated the Twenty-second
day of January, in the year of our Lord One thousand eight hundred and
fifty-eight.
The first part of my improvements applies principally to the machinery
shewn on Sheets 1 to 14, both inclusive, of the Drawings accompanying
the Specification of my aforesaid Patent, and consists in the modifications
of such machinery which are herein-after described, and which will be
explained and illustrated by the Figures on Sheets 1, 2, 3, and 4, of the
Drawings accompanying this Specification.
Fig. 1 is a front elevation; and Fig. 2 is an end elevation (opposite to the
headstock end of the machine), giving a general view of the framing and
driving apparatus, and other parts; Fig. 3 is a front elevation shewing parts
of the headstock; Fig. 4 is an elevation of part of the back side of the head,
stock; and Fig. 5 is a cross sectional elevation through the headstock; Fig. 6
is a front elevation, shewing front parts of the headstock and two heads of the
machine; Fig. 7 is a cross sectional elevation shewing parts of the spooling
head; and Figs. 7, 8, 9, 10, 11, and 12, are views of detached parts of the

page_text: machinery; Figs. 13 and 14 are diagrams for illustrating the forms of the
cams employed.
My improvements consist, firstly, in a new arrangement of the countershaft
and apparatus connected therewith, by which the machine receives motion.
The countershaft is placed in bearings on the framing of the machine, and
passes from one end of the machine to the other; the stopping and starting
rod is placed in the front of the machine, and is connected with a vertical
shaft on which the belt guide is fixed. The cone drums for diminishing the
speed of the machine as the spools increase in diameter are placed in bearings
carried on the framing of the machine, and the belt guides of the cone drums
are connected with mechanism which actuates them, so as to traverse the belt
on the cone drums; this mechanism consists of a peculiarly arranged cam,
partly rotated by the first motion shaft, and partly by the cam shaft which
effects the changes of the spools.
The Figures on Sheet 1 illustrate the first part of the improvements above
referred unto. It will be seen that the framing from the headstock is con-
tinued upwards, and is intended to be secured by brackets to the ceiling of the
room in which the machine is to be worked, so as to give steadiness to the
framing. is the countershaft; x', the fast and loose driving pulleys; x² is
the belt guide for these pulleys, and is fixed in the vertical shaft a³ carried by
bearings secured to the end framing. On the lower end of the vertical
shaft (3) an arm a is secured, which is jointed to one end of the stop rod a¹,
the other end of which slides in a guide formed in a bracket secured to the
front framing of the machine. One of the two cone drums (25) is fixed on
the headstock end of the countershaft (x), the other is fixed on a second
countershaft xº, upon one end of which shaft a pulley * is fixed, which com-
municates motion by a belt to the first-motion shaft (a) of the machine. The
two cone drums (25) have each a belt guide attached to a rod (7) sliding in a
guide fixed to the framing at one end, and jointed to one arm of a bell-crank
lever (s) at the other end, which lever has its fulcrum (x) in a bracket
secured to the framing. The two bell-crank levers (28) are connected by a
rod (10), which is continued downwards and jointed with a lever (a), having
its fulcrum (12) on a stud secured in the framing. The connecting rod (10)
is provided with a screw-adjusting link, by which the position of the belt
working on the cone drums may be regulated. The lever " is actuated (see
Figs. 4 and 5, Sheet 2,) by a cam 3 on the cam shaft m. When the
machine is winding thread the first motion shaft a is rotating, and the cam 213
is driven from this shaft by a worm 1, which gears with a worm wheel 15 on
one end of a shaft a16, rotating in a bearing fixed to the framing. On the

page_text: other end of this shaft a pinion x" is fixed, which gears with a wheel 18 on a
stud secured in the framing; upon the boss of the wheel x is a pinion 10,
which gears with a wheel loose on the shaft m. This wheel carries one or
more clicks, which are caused by a suitable spring to enter into ratchet teeth
formed on the back of the cam 213; such can will by this means be carried
round by the clicks of the wheel a, so long as such wheel is in motion. The
cam a (when in rotation) by acting on the antifriction bowl on the lover
will gradually cause the rod 20 to rise and traverse the belt, so as to diminish
the speed of the machina. When the machine has filled the spools with
thread, the canals will not have arrived at the position in which it should.
stand at the commencement of the winding of the spools, but before the
commencement of the winding of a new set of spools the revolution is com-
pleted by the following arrangement of machinery :-A stud adjustable in a
slot in an arm 20 fast on the cam shaft m, is brought by the continued
working of the machine against a projection on the face of the cam a", and
thus when the shaft m rotates (which it does once for every change of spools),
the cam is carried forward so as to complete its revolution, and be in the
right place for the commencement of the winding of each set of spools. As
soon as this is done the cam 23 will cease to sustain the lever (owing to its
peculiar form), and such lever will be caused to descend by the weight 2 on
the end of the lever a", when the winding begins, till the antifriction bowl on
the lever again rests upon the cam 13; this decent of the weight 23
traverses the cone drum belt till the greatest speed is attained. The ratio in.
which the speed is to be diminished as the spool fills will depend upon the size
of the spool to be wound, as will consequently the amount of rotation to be
given to the cam 13 while the machine is winding. The amount of rotation
may be regulated by "change wheels" in the manner well understood. In
the Specification of my aforesaid Patent a cam on the shapor cam shaft (i) is
described for traversing the belt to vary the speed of the machine; but I find,
that though this will answer the purpose, it has a bad effect on the traverse
motion for distributing the thread, as it causes irregularity by the strain it puts
upon the shaper cam shaft (i), which should have as little work to do as
possible. When I do not employ the above described mechanism for
diminishing the speed of the machine, I sometimes substitute for the cone
drums a series of pulleys commonly termed "speed pulleys" (see Figs. 16
and 17, to be herein-after described,) by which I can readily obtain the best
uniform speed for each different size of spool required to be filled with yarn
or thread.
My improvements consist, secondly, in the application of a brake to the

page_text: pulley (a on which the belt works, when giving motion to the cam shafts
and m, which effect the changes of the spools; this brake arrests the motion
of those shafts without shock, and is actuated by a cam on the belt changing
cam shaft (4),this arrangement being a substitute for the click which catches
in a notch on a dix (), on the spool changing cam shaft m, described in my
aforesaid Specification. The brake above referred to consists of a lever w,
having its fulcrum ou a stud secured in the framing of the machine, a projec-
tion from this lever is made concave, so as to fit the upper side of the pulley
a5 which is uncovered by the driving belt, this lever is acted upon by a weight
or spring which presses it upon the upper surface of the pulley (as) when
permitted to do so by the action of the cam W₁ on the belt changing cam
shaft b.
My improvements consist, thirdly, in a new arrangement of the cam (6¹º)
and parts actuating the brake (a), described in my aforesaid Specification,
for stopping the winding part of the mechanism, so as to bring the brake
into action before the thread guides are lifted from the spools. Instead of
both ends of the brake belt (a¹0) being attached to the lever (a"), as described
in my aforesaid Specification, one end only is attached to the lever, the other
end being secured to a projection from the framing, as shewn in Fig. 5; the
cam 610 is shaped and arranged on the shaft (64) so that it will have produced
the movement in the lever (a") to tighten the brake belt (a) in the first
60 degrees of the rotation, or thereabouts, of the shaft 64, and the cam o', for
actuating the thread guides is shaped (see Fig. 7) and arranged on the shaft
(64) so that it does not begin to lift the thread guides till the shaft b4 has
rotated 90 degrees; by this incans one operation is certain to be completed
before the other is commenced.
My improvements consist, fourthly,in a new arrangement of the mechanism
which rotates the cam shaft for advancing the "shaper" in my new arrange-
ment instead of connecting the "lever" with the oscillating part h³ directly,
the lever is connected with a lever (having its fulcrum "ou the traverse
screw headstock h) which is connected with the oscillating part ha. The
mechanism described in my aforesaid Specification for giving the movement
to the shaper cam shaft i,when the changes of spools have been effected is also
modified. The shaft i is made to extend to the back of the machine, and a
is secured upon it, this disc is acted upon by the click carried by the
jointed with the rod i which at its lower end is jointed with an arın or
crank 4, which I employ in place of the cam 4 described in aforesaid
disc
arm
my
Specification. The screw is provided with a "tail-pin screw" h¹× to
prevent end movement; see Fig. 3.

page_text: My improvements consist, fifthly, in a simplified arrangement of the
mechanism which transmitts motion to the thread guides for lifting or depress-
ing them; by this arrangement one of the two shafts and cams described for
this purpose in my aforesaid Specification is dispensed with. The thread
guides are actuated by the shaft j, passing along the back of the machine,
having fixed upon it an arm jl for each thread guide, which arm is connected
to the thread guide by a rod d. The cam o' on the shaft & lifts the thread
guides when the winding of each set of spools is finished by acting upon an
antifriction bowl carried on one arm of the bell-crank lever o², which is
secured on the shaft j. To one arm of this lever o² one end of a cord or chain
is attached, which passes over a pulley (70), and to the other end thereof a
weight is secured which causes the thread guiedes to press upon the spools
when winding. One of the arms of the bell-crauk lever o². carries an adjusting
set-screw which by the point of the screw coming against the framing of the
machine prevents the weight q' from bringing the thread guides down with
too much force against the empty spools (see Fig. 7). The extra pressure for
polishing the thread is imparted to the thread guides by means of the cam
projection 8, lever, rod ", and arm 2, on the shaftj, as described in my
aforesaid Specification; the shaftj answering the purpose of the shafts j, and
02 described in my aforesaid Specification. In place of using the cam projec-*
tion for obtaining the extra pressure on the thread guides, a cam or part
73 (see Fig. 7) may be placed on the shaft 64, and an arın may be secured ou
the shaft, the end of the arm carrying an adjusting set-screw, the point of
which will be made to comeagainst the cam or part, when the spools are within
a few layers of being fall, this by the strain of the parts will resist the rise of
the thread guides as the spools fill, and will give the extra pressure for polishing
the thread, the first part of the movement of the cam shaft & will take away
the obstruction to the rise of the thread guides, as the cam or part (³) upon
which the point of the adjusting screw rests will pass from under it.
My improvement consists, sixthly, in a new shape and construction of the
cradlepiece(g), which is no longer used for sustaining the spool while it is being
placed upon the spindle; and in an improved shape and arrangoment of the
cams for actuating the spindles, this alteration being consequent upon my
dispensing with the cradle as a support, and the improved mode of feeding the
empty spools herein-after mentioned. By reference to Figs. 6 and 7 the shape
of the improved cradle piece (9') will be seen; it is only used for pushing the
full spool from the spindle, and for carrying the knife (2), which makes the
incision in the head of the spool for securing the end of the thread. This
knife is fixed to the cradle piece (g') by the screw (g'). The shape aud

page_text: arrangement ofthe cams for actuating the spindles and cradles will be herein-
after described along with the other cams employed in the machine.
My improvements consist, seventhly, in a new arrangement of the ram,
which feeds the empty spools, which ram is made by means of a spring applied
thereto to carry the empty spool and hold it opposite to the spindle, the said
springg iving way to allow the ram to be drawn back, and thus get clear from
the spool, when it is placed upon the spindle. The ram n¹ is actuated by a
cam (on the shaft ), arm n, shaft n, arm ne, and link n', as described in
my aforesaid Specification. The arm is loose on the shaft 5, but it is made
to move with such shaft by being secured to an arm no* (as shewn in Figs. 6
and 7), and thus permits adjustment. The new construction of the ram (n')
is shewn by Figs. 8 and 9, which represent respectively a longitudinal section
and plan view of the ram detached. A spring 2, which is secured to the ram
case, is described in my aforesaid Specification for preventing the spools from
moving forward till pushed by the ram; such a spring is also used in my new
arrangement, but it is secured to the ram n', and moves with it. The spool,
when it drops from the feeding hopper or trough n, rests on the ram, as shewn
by (x) in Fig. 8; the ram carries the spool opposito to the spindle, and when
the spindle has passed through the spool, it will be obvious that there is
nothing which will prevent the ram from being withdrawn, as the end of the
spring 2 will descend and pass under the spool. It will be seen that the
feeding trough is open, having only narrow ledges at the sides to keep
the spools from moving endways, and a bent bar (n), as shewn in Figs. 6
and 7, to keep the spools down against the trough.
My improvements consist, eighthly, in the application of a V-piece of
thin metal to the side of the feeding ram (21), which assists to place the
thread in the incision made in the end of the spool. This V-piece (n) is
shewn attached to the ram in Figs. 8 and 9, the bottom of the V being
slightly in advance of the edge of the spool (x)..
The Diagram, Fig. 11, on Sheet 4 of my aforesaid Specification, illustrates
the mode in which the thread is forced into the incision formed in the head
of the spool, which is accomplished (as described in my aforesaid
Specification), by the edge of the empty spool when pushed on to the
cradle. This V-piece (³), acts upon the thread in place of the edge of
the spool, the angle or bottom of the V-piece being opposite the incision
made on the edge of the spool.
My improvements consist, ninthly, in the actuation of the thread presser by
a separate cam and independently of the feeding ram, and the making of the
thread presser (p) act also as the thread cutter, thus dispensing with the

page_text: shaft c, armes, and cutter e, described for this purpose only in my aforesaid
Specification. The actuation of the thread presser by a separate cam inde-
pendently of the feeding ram, gives greater facility for adjusting the action of
the operating parts. The arrangements of machinery for these purposes are
as follows: The thread presser lever (p) has its fulcrum on a stud on the
side of the ram case, as described in my aforesaid Specification, but the lever
(p) is now made in the bell crank form, as shown in Figures 6 and 7 of the
Drawings accompanying this Specification. The arm of the lever (po) carrying
the thread presser p8, is lifted by a spring (p1) attached to the stand part of
the ram case and to the lever, as shewn in Fig. 7. The thread presser and
cutting levers p are actuated by a shaft e, secured in bearings on the framing
and arms e, which carry adjusting screws e, as shown in Fig. 7. When the
lever p' is to be actuated to press upon the thread to assist in placing it in the
incision made in the edge of the spool, motion is given to it by a single-acting
cam p" on the shaft l, which acts upon an antifriction bowl carried by an
arm fast on the shaft c. The bent wire (p) carried by the lever p'; which
presses upon the thread, is sharpened at the point to form a kuife, so that if
depressed when the spool is on the spindle it will come in contact with it in
the same manner as the knife e, described in my aforesaid Specification, and
will cut the thread; the movement for this purpose is given by the same
means as those described in my aforesaid Specification, namely, a cam
projection 2, lever e¹ (on a fulcrum e2), rod e³, and arm e, fast on the
shaft c.
My improvements consist, tenthly, in using instead of the brush (d) for
putting friction upon the thread, described in my aforesaid Specification, a
finger acted upon by a spring, the surfaces coming in contact with the thread
being steel pieces arranged so as to be readily replaced when worn out, the .
amountof friction put upon the thread by the finger being adjustable by a screw.
Fig. 10 is an end, Fig. 11 a front, and Fig. 12 a plan view of the arrange-
ment for putting friction on the thread, and carrying the thread guide. The
traverse bar d is round, and extends from one end of the machine to the other;
it is prevented from turning by the arm do secured upon it, which slides
upon the stud d fixed in the end of the headstock part h (see Fig. 3.) The
traverse bar d forms the axis of the thread guide holders, as shewn in Fig. 7;
these are held in their places by collars secured on the bar d against each end
of the barrel or axis part . From one end of the barrel part (d¹) an arm (d³),
extends, having a hole in it forming a socket, in which the thread guide is
secured by a set screw (d"); from the other end of the barrel part another
arm 3 extends, to which the rod is connected. The end of the rod dis

page_text: made as shewn in Fig. 10 (with an adjustable screw coupling) s as to be
readily connected or disconnected with the arm d³. The finger d¹³ for putting
friction upon the thread has its fulcrum d" carried by projections from the
barrel I part ; one end of the finger 13 carries a piece of hard steel secured
by being dovetailed in the finger, another similar piece of steel being a dove-
tailed into a projection from the upper part of the arm d³. The steel piece in
the finger is caused to press upon that carried on the arm d³ by the
spring d secured as shewn in Fig. 11, which acts upon the point of the
screw ; for adjusting the pressure this screw passes through the end of
the finger d¹³, as shewn. 3 are pins or projections from the barrel part d',
forming guides to the thread passing between the steel pieces. The thread is
drawn from the end of the bobbin q, and passes over a rod q', then through a
wire "curl" 92 between the projections 3 and the steel pieces through the
guide or distributor and on to the spool.
Fig. 13, Sheet 4, is a diagram of the cams on the shafts and an employed
for effecting the changes of the spools, shewing their shape and relative times
of action. The dotted lines numbered from 0 to 360 represent the length or
circumference and datum line on which the cams are supposed to be con-
structed, and the full lines represent the paths of the cams; the point
marked'0, and that marked 360, represent the same point on the cams,
the numbers being degrees of the circle. The antifriction bowls upon which
the cams act are all at the point marked 0 or 360 at the beginning or end of
the change of spools. The cam f4 on the shaft m makes the movement to
discharge the spool between 0 and 50 "dwells" (or produces no movement),
between 50 and 70 makes the return movement to receive tlie spool between
70 and 120, and dwells between 120 and 360. The cam g² on the shaft m
"dwells" between 0 and 110, and produces the movement which pushes the
spool from the spindle c³ to the spindle f¹ between 110 and 160, dwells
between 160 and 205, and makes the return movement between 205 and
258, and dwells between 258 and 360. The cam c on the shaft m dwells
between 0 and 10; produces the movement to give clearance to discharge the
spool between 10 and 40, dwells between 40 and 72, produces the back
movement to deliver the spools between 72 and 103, dwells between 103 and
145, produces the movement to allow the empty spool to be fed between the
145 and 210, dwells between 210 and 285, produces the movement which passes
the spindle through the empty spool between 285 and 350, and dwells
between 350 and 360. The cam n³ on the shaft dwells between 0 and 215,
produces the movement which feeds the empty spool between 215 and 250,
dwells between 280 and 325, and makes the return movement between 325

between 0 and SS, produces the movement which brings the point (p)
against the spool between SS and 160, dwells between 160 and 310, makes
the back movement between 310 and 358, and dwells between 35 and
360. The cam 211 on the shaft dwells between 0 and 105, produces the
movement which depresses the thread between 105 and 160, dwells between
160 and 168, produces the movement which lifts the thread presser
between 168 and 180, and another movement which produces à descent of
the thread presser between 180 and 195, dwells between 195 and 200, and
produces the back movement to be out of the way of the ram between 200
and 260, and dwells between 260 and 360.
Fig. 14 is a diagram of the cams on the shaft 64, which has two move-
ments for each change of spools, one movement from 0 to 180, the other from
180 to 560. The cam 60 produces the movement which puts on the
brake (a) between 0 and 45, dwells between 48 and 180, and produces the
movement which releases the brake between 180 and 200, and dwells between
200 and 360. The cam W produces the movement which lifts the brake
from the pulley a5 between 0 and 180, and the movement which puts on the
brake between 180 and 360. The cam o dwells between 0 and 90, and
produces the movement to lift the thread guides between 90 and 150, and the
movement to lower the thread guides between 180 and 360. The cam 63
produces the movement which traverses the belt from the pulley ² to the
pulley a between 0 and 180, and the back movement between 180 and 360.
I have now described the improvements which apply to the machine shewn
by Sheets 1 to 14, both inclusive, of the Drawings accompanying my aforesaid
Specification, and such parts of my improved machine as have not as well as
some parts which have been herein-before mentioned and referred unto aro
substantially the same in arrangement, construction, and modes of action,
as those described in my aforesaid Specification. Such of the parts shewn
by the accompanying Drawings in Figures 1 to 12, both inclusive, as I have
not found it necessary to mention or refer to in describing my present improve-
ments, I have marked with the same letters and figures of reference as are
used for the same or corresponding parts in my aforesaid Specification, so
that the Drawings may be readily understood. In the Drawings accompany-
ing the Specification of my aforesaid Patent, the Figures on Sheets 16, 17,
and 18 illustrate what I term the single bobbin machine, while that machine
which I have herein-before described I term the double bobbin machine.
And the second part of my present Invention relates to arrangements by
which some of the peculiarities of the single bobbin machine are imported in a

page_text: modified form into and combined with the double bobbin machine in such a
manner as to change it into a single bobbin machine applicable to the winding
of thread upon spools of different sizes. I shall first describe the mechanism
employed in carrying out my improvements, and afterwards its mode of action,
by reference to the Figures on Sheets 4, 5, and 6,. of the accompanying
Drawings. Fig. 15 is a diagram shewing the form and times of action of the
cams employed in the single bobbin machine; Fig. 16, a front elevation of
part of the machine; and Fig. 17, a cross sectional elevation; Fig. 18, a front
sectional elevation of the operating parts; and Fig.19,a cross sectional elevation;
Fig. 20, a detached view of the hook, spring, knife, and part of bracket
carrying the same. The framing A, headstock, and winding parts of the
mechanism, are substantially the same in this machine as in the double bobbin
machine, the shafts and positions of the cams and levers, and other parts con-
nected with the mechanism for changing the spools in the double bobbin
machine are retained as far as practicable in this machine, but are wholly or
partly applied to different uses, as herein-after described. It will be seen by
reference to Fig. 18, that the spindle C5 on which the spool is placed, is
arranged and rotated in a similar manner to those described in my aforesaid
Specification, and receives end movement from the cam c 14 (on shaft m.) lever
C¹³, sliding rod C7, and arm C", as described in my aforesaid Specification.
The end of the spindle C5, when through the spool, enters an hollow tube f¹,
carried by the arm f fixed on the sliding rod f, which has end movements
from the lever f and cam f on shaft m. The finger for pressing the thread
to one side of the thread guide is secured on the sliding rod g, which receives
end movement from the lever g³ and cam g² on the shaft m. The two armed
lever p², having its fulcrum on a stud p³x in the headstock C4, carries a spring
point p, secured by a set screw p2x, and also a knife 2, for making the incision
in the head of the spool (x). The lever 2 is connected by a rod p (having
an adjustable coupling link) with an arm 27, on a shaft p3, which receives
motion from a camp on the shaft, which acts on an antifriction bowl carried
by the arm 15 fast on the shaft p³. The hook V³ is made to slide in a recess
formed in the bracket V secured to the framing; the hook is kept in the
recess in the bracket by a spring vl, secured by the screws V4, which spring
also serves to hold the end of the thread against the hook, the knife co for
cutting the thread is secured by a set screw e as shewn. The hook V³ receives
end movement from the arm es, fixed on the shaft e, a pin in the lower end of
the hook fitting into a slot formed in the end of the arın e'. The shaft e
receives movement from the cam e on the shaft (, which acts on an anti-
friction bowl carried by an arm e¹, loose on the shaft p³, the arme¹being jointed

page_text: with a link e³, which is jointed with an arm et fast on the shaft e. The empt
spool (X) is fed by means of a bracket g', which is fixed to the framing.
which bracket forms a cradle through which the hollow tube f' (carried by
the spindle f) can pass. The empty spool (X1) to be fed, is placed on the
cradle g', in the position shewn in Fig. 19, being prevented from rolling
down the side of the cradle g' by the end of the arm n' (as shewn), this arm
is fixed on a shaft n", which receives motion from a cam n³ on the shaft l,
which acts on an antifriction bowl carried by the arm nt, fast on the shaft n³.
I have now described the operating parts of one head for changing the
spools, and will next describe the mode of action of the machine. The thread
is wound upon the spool as in the double bobbin machine herein-before
described, and the thread guide lifted in the same manner away from the
spool when the winding is finished, then the first movement is the descent of
the arm p², which causes the knife 2 to enter the edge of the spool and make
an incision, the arin p² then ascends sufficiently to withdraw the knife from the
incision, but leaves the spring point p which is in advance of the knife 2 against
the spool: while this operation has been going on the finger g (which has
been standing near the arm fe during the winding of the spool) has moved to
the position in which it is shewn in Fig. 18, the hook part having caught hold
of the thread extending between the spool and thread guide, and a little
before the finger g' has arrived, in this position the hook V³ has risen to the
position shewn in Fig. 19. It then returus, and in its downward movement
catches the thread between the thread guide and the finger g4, and drags it
down into the incision formed in the head of the spool, the downward move-
ment of the hook being continued till the end of it has passed the point of the
spring VI, and the edge of the knife eo which cuts the thread, so that the end
connected with the spool is free, but that end of the thread which is nearest to
and connected with the thread guide is held fast by the spring (VI) against
the side of the hook (V3), which remains stationary when the thread is cut
As soon as the hook V3 has caught the thread the finger g is caused to begin
its back movement to the piace in which it stands when the machine is
winding, and when the hook V3 has completed its descending movement, the
arm is caused to ascend into the position in which it stands when the
machine is winding, and the cams and C14 begin to act, one to withdraw
the spindle Co from the spool (X), the other to withdraw the tube f¹ to give
sufficient clearance to allow the spool to fall into the trough in front of the
machine, the spool being stripped from the spindle C by coming against the
end of the bush which forms the bearing of the hollow shaft C³. When
the spool has been delivered the return movement of the spindle C5, is made

page_text: to its first position as when winding, and at the same time the hollow tube fi
has been withdrawn from the cradle (g), when the lever n' is drawn back by
the action of the cam n³ on the shaft 1,and this allows the empty spool to roll
to the bottom of the cradle (g'), the return movement of the hollow tube f¹
then takes place, and forces the empty spool on to the spindle C5 against the
shoulder formed on it, between which and the end of the spool the thread is
pinched, the thread passing in such a direction between the thread guide and
the hook V3 and spring V₁ as to come in front of the shoulder on the spindle
C, when it is pushed back after being withdrawn from the full spool. When
the empty spool is on the spindle the hook V³ is caused to ascend sufficiently
to release the end of the thread from the spring V₁, and this movement
completes the spool changing operations, and the winding commences. The
empty spools are placed on the cradle g' one at a time. This machine can
be readily altered from one size of spool to another by "change wheels" and
adjusting arrangements" without changing the cams.
I shall next describe the diagram, Fig. 15, of the cams on the shafts / and
m of the single bobbin machine. The cam fou the shaft m dwells (or
produces no movement) between 0 and 140, produces the movement for giving
clearance for the full spool to fall between 140 and 146; dwells between 146
and 182,produces the movement which allows the empty spool to fall into the
cradle between 182 and 240, "dwells" between 240 and 270 and produces
the movement which pushes the empty spool from the cradle (g')
on to the
spindle (C5) between 270 and 330, and dwells between 330 and 360. The
cain on the shaft m "dwells" between 0 and 20, produces the movement
which catches the thread between 20 and 60; dwells between 60 and 90,
produces the back movement between 90 and 145, and dwells between 1.45
and 360. The cam C14 on the shaft m dwells between 0 and 140, produces
the movement which discharges the full spool between 140 and 195, dwells
between 195 and 215,and produces the return movement to receive the spool
between 215 and 270, and dwells between 270 and 360. The cam p' on the
shaft dwells between 0 and 12, produces the movement which makes the
incision between 12 and 36, dwells between 36 and 62, produces the move-
meut to lift the knife out of the incision between 62 and 80, dwells between
S0 and 90, and produces the movement which lifts the point away from the
spool between 90 and 107, and dwells between 107 and 360. The came on
the shaft "dwells between 0 and 10, produces the movement which lifts the
hook V³ to catch the thread between 10 and 57, dwells between 57 and 63,
produces the downward movement of the hook between 63 and 110, dwells
between 110 and 340,produces the movement which releases the thread from

page_text: /
the pinching spring between 340 and 350, and dwells between 350 and 360.
The cam 3 on the shaft dwells between 0 and 230, produces the move-
ment which allows the empty spool to drop into the cradle between 230
and 255, dwells between 258 and 302, produces the return movement
between 302 and 330, and dwells between 330 and 360.
Such parts of the machine as are shewn in Figures 16, 17, 18, 19 and 20,
and which have not been mentioned or referred to are substantially the same
as those used in the improved double bobbin machine herein-before described,
and are marked with the same letters and figures of reference as are used on
Figures 1 to 12 (both inclusive) of the accompanying Drawings.
I have now particularly described the nature of my Invention and the
manner of carrying the same into effect, and desire it to be understood
that I claim as my Invention,-
Firstly, the combinations and arrangements of mechanism forming the
improvements herein-before described in the double bobbin machine when
used singly or when several or all of them are combined and used in the
same machine.
Secondly, I claim the combination and arrangements of mechanism forming
the improved single bobbin machine, substantially as herein-before described.
In witness whereof, I, the said William Wild, have hereunto set my
hand and seal, this Eleventh day of September, in the year of our
Lord One thousand eight hundred and sixty.
