Improvements in Spooling Machines.
JAMES BALDERSTON, of Greenlaw Terrace, Paisley, in the County of Renfrew,
North Britain, Engineer and Mill Manager, do hereby declare the nature of this
invention to be as follows:-
This invention which relates to improvements in spooling machines is specially
applicable to the class of machines known as the "Conant" spooling machines &
has reference more particularly to that part commonly called the "builder" or
"shaper."

The invention consists in having the "builder " or shaper" so that it may be
adjusted to "build" up the thread upon bobbins of any bevel or size & to be
adjusted to build up any required number of rows or layers of thread on the
spool.
My improvements consist in the employment of a suitable bracket fixed to
the bed of the machine, or attached to the head, or cast as part of the head having
two spindles.

The top spindle has fitted on it, two "builders " ог
" of suitable or
shapers
convenient size &, having a suitable or convenient number of teeth so arranged
that they may be moved either way and maintain the same line of teeth, each
"builder "
or "shaper," having a groove in the centre for clutches, which expand
& contract them.
The two clutches are held in position by a slot plate, running parallel with the
spindle & are actuated by two adjustable slot guides, fixed to a rising & falling
stud plate, which runs the whole length of the bracket & is actuated by a cam on
the second spindle, that gives a uniform rising & falling motion.
This motion is derived from the first spindle so arranged by spur gear, that the
second shaft usually makes one revolution for the number of rows requisite to fill
the spool, but may
be so arranged as to make part of a revolution.
The "builder or top-shaft if desired, may be only partially turned, or as many
turns given, as may be necessary to complete the required number of rows, or
layers, of thread, to fill the spool under operation, this being accomplished by the
employment of suitable change gear or gearing on the spindles or shafts.
"
When the machine is put in motion the fingers in contact with the "builder
or "shaper" travel over the end of same, causing them to move one tooth, which
communicates motion through spur gear to the cam on the second spindle carrying
the ordinary builder cam, & thereby raises the stud plate with slot guides which
may be adjusted to any bevel by thumb screw & nut even whilst spooling. The
tail of the clutch working in the slot guide & slot plate gives the necessary amount
of expansion to the "builder" & "shaper," to suit the bevel required.
When the cam on the second spindle has made one revolution, or it may be part
of a revolution, as necessary to fill the spool, the stud plate drops into position to
repeat the operation.
The "
builders" or "shapers" do not require to come out of gear with the
fingers or lips of the machine, nor revolve back to the starting point as they
simply close at the finish of one spool & are ready to go on with the next.
It is sometimes desirable to finish the building at the outer end of the spool, this
I accomplish by making a suitable alteration in the shape & position of the ordinary
stop motion as applied & used in the "Conant" spooling-machines.

By a suitable arrangement of gearing or change-gear' so that the bottom
gear & the intermediate may be readily taken out of gear without disconnecting
the top gear & the intermediate, I am able to turn the bottom shaft back by hand

page_text: to any point & thereby close the "builders" to any part of the traverse required
for the refilling or turning the spools.
When the top gear is such as to make the bottom gear equal to an odd number
of rows, it is possible under ordinary circumstances to put the intermediate in gear,
with bottom gear at the wrong tooth, & thereby stop the machine at the wrong
end of the spool, this I prevent, by making the change gears, & intermediate, so
that they will only enter into gear at the proper tooth.

Improvements in Spooling Machines.
JAMES BALDERSTON of Greenlaw Terrace Paisley in the County of Renfrew
North Britain, Engineer and Mill Manager, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention which relates to improvements in spooling machines is specially
applicable to that class of machines known as the "Conant" spooling machines and
has reference more particularly to that part commonly called the "builder" or
shaper."
The invention consists in having the builder or shaper so that it may be adjusted
to build up the thread upon bobbins of any required bevel or size and be adjusted
to build up any required number of rows or layers of thread on the spool. My
improvements consist in the employment of a suitable bracket fixed to the bed of
the machine or attached to the head or cast as part of the head having two
spindles.
$6
or
The top spindle has mounted on it by slot way and feather, two "builders
shapers" capable of lateral movement, along the said spindle by the aid of
clutches. These "builders" or shapers are constructed after the manner of the
teeth of gears. The said teeth or projections being, of any suitable size and
having any suitable or convenient number of teeth, which are slightly rounded at
their outer ends. The teeth are so arranged that they may be moved either way
and maintain the same line of teeth.
Each builder or shaper has a groove cut in it, for the reception of clutches which
expand & contract the builder or shaper laterally. The two clutches are held in
position by a slot plate running parallel with the spindle, and are actuated by two
adjustable slot guides fixed to a rising and falling stud plate, which runs the whole
length of the bracket, and is actuated by a cam on the second spindle, that gives a
uniform rising motion & thereby a uniform opening or expanding motion to the shapers.
The motion thus imparted to the clutches is derived from the first or top spindle
aforesaid, being so arranged by spur gear that the second shaft usually makes one
revolution for the number of rows requisite to fill the spool, but the mechanism may
be so arranged as that the said second shaft or spindle will make only a part of a
revolution to accomplish this end.
The builder " or top shaft upon which it is mounted may if desired be only
partially turned, or as many turns given to it, as may be necessary to complete the
required number of rows or layers of thread to fill the spool under operation, this
being accomplished by the employment of suitable change gear or gearing on the
spindles or shafts.
32
When the machine is put in motion, the fingers on their backward and forward
traverse, come into contact with the " "builders or "shapers," thus engaged
causing them to move one tooth, giving to the top shaft a rotary motion. This
rotary motion is communicated through spur gear to the second spindle carrying

page_text: the ordinary builder cam for raising the guide as used in the "Conant" spooling
head, and also the cam for raising the stud plate with slot guides which may be
adjusted to any required bevel by thumb screw and nut even whilst spooling.
The tail of the clutch working in the slot guide and slot plate gives the
necessary amount of expansion to the "builder or "shaper" to suit the bevel
required.
When the cam on the second spindle has made one revolution, or it may be only
a part of a revolution as necessary for the amount of layers required to fill the
spool, the stud plate drops into position and draws in or contracts the shapers to be
ready to repeat the operation of building up a fresh bobbin.
The builders" or shapers" do not according to my present invention require
to come out of gear with the fingers or lips of the machine, nor revolve back to the
starting point, as they simply close at the finish of one spool and are ready to go
on with the next.
By a suitable arrangement of gearing or change gear, so that the bottom gear
and the intermediate gear may be readily taken out of gear without disconnecting
the top gear, and the intermediate; I am able to turn the bottom shaft back by
hand to any point and thereby close the "builders to any part of the traverse
required for the refilling or turning the spools.
Where the top gear is such as to make the teeth of the bottom gear equal to one
or any odd numbers of rows it is possible under ordinary circumstances to put the
intermediate in gear with the bottom gear at the wrong tooth, and thereby stop
the machine at the wrong end of the spool.
This I prevent by forming on the cheek of the intermediate spur wheel a flange
into which are cut grooves or indentations by which means they will only enter
into gear at the proper tooth.
In order that my said invention may be properly understood & readily carried
into effect I will proceed to describe the drawings hereunto annexed.
Fig. 1 is a front elevation, Fig. 2 is a plan of the same, Fig. 3 is a transverse
vertical section illustrating my improvements as applied to a spooling machine of
the "Conant" type.
Figs. 4 & 5 are respectively end view & plan of how the stop motion is effected,
when it is desired to complete the building up of the bobbin at the outer end or
edge thereof as hereinafter fully referred to.
Illustrated in the drawings A is the bracket attached to the bed of the machine.
The two spindles carried in the said bracket A are represented by B & C.
The upper or top spindle B has mounted on it, by slot way & feather the
builders or shapers D and E. The builders or shapers D & E are constructed
somewhat after the manner of the teeth of gears as seen in Fig. 3.
The teeth or projectious which may be of any suitable number & size are rounded
at their outer ends for purposes hereinafter explained.
33
The builders or shapers" D & E are capable of lateral expansion in
opposite directions to each other along the said spindle B by means of clutches F
& G carried in grooves cut in the "builders or "shapers" D & E. In rotary
motion the "builders or shapers" turn with the said spindle B, and each tooth
represents two rows as in the ordinary "Conant" shaper.
"
The rear ends or stems of the said clutches are held in position by a slot plate H
(Fig. 3) in such manner that any but a lateral movement is impossible. The said
stems of the clutches have mounted upon them and are actuated by the slot
guides I & J. These guides work in two slots, formed obliquely, or at an angle
by the manner in which the two L shaped plates K & L are arranged relatively
one with the other as seen more particularly in Fig. 1.
The plates K & L aforesaid are pivoted at k, and 1, to the rising and falling stud
plate M. The upper and lower ends of the plates K, and L, are adjustable by
turning the milled heads of the regulating screws K' and L', that is to say the two
ends m and n of the said plate K and L may be brought down to or separated
further from each other. In Fig. 1 they are shewn separated at their maximum

page_text: distance or thereabouts, and are or may be clampeil in that position, or at a more
less taper or bevel by the milled nuts O within the curved slots N and N¹ formed
in the lower major portion of the said plate M.
Mounted on the one end of the upper or top spindle B is the pinion P, which
gears with an intermediate spur wheel Q. This spur wheel Q again gears with the
pinion R formed on the lower spindle C.
By the gearing the aforesaid motion is imparted to the spindle C.
The spur wheel Qaforesaid is clamped eccentrically by the stud Q within the
quadrantal slot Q³ to permit of its being geared with various sized pinions, and is
so arranged that it may be thrown in & out of gear with the pinion R and still
remain in gear with the pinion P.
Mounted centrally or thereabouts upon the spindle C, is a cam S, which may be
a single or multiple cam.
The one represented in Fig. 3, is a double or multiple cam.
Another cam T of a form corresponding to that of S (known as the builder cam)
is also mounted upon the end of the spindle C. The object of the cam S is to raise
the rising & falling stud plate M while that marked T is for raising the guide as
used in the "Conant" spooling head.
When the machine is in operation at each backward & forward traverse of the
fingers U and V (a mechanical arrangement well known to the "Conant" spooling
machine) the teeth or projections of the
"builders or "shapers" D and E, become
engaged the bevelled or inclined edges of the said fingers passing partially under-
neath the projections of the "builders or "shapers" tend to and do raise them,
which cause them respectively to move the distance of one tooth in the direction
indicated by the arrow Fig. 3, giving to the upper shaft or spindle B as will be
understood a slight rotary motion.
"
The rotary motion is communicated by the spur gearing hereinbefore referred to
to the lower spindle C.
"
It will be seen that at each movement of the teeth or projections of the "builders'
or "shapers" due to the clutches and mechanism aforesaid, they progressively open
out in the direction indicated by the arrows consequently the fingers U and V will
have to traverse a correspondingly increasing distance. Thus by a series of
progressive or backward and forward movements the bobbin is filled. When this
operation is completed the plate M falls into its normal position ready to be
operated upon again by the cam S.
It is here explained that when the double or multiple cam S is employed
and the number of teeth of the builder or shapers are made equal to the number
of teeth of the pinion P then the number of teeth of the pinion R will coincide
with the number of the rows required to fill the spool or bobbin, but when it is
desired to use the single cam the number of teeth required in the pinion R will be
equal to half the number of rows required to fill the bobbins. When the pinion P
consists of twice the number of teeth of the builders or shapers it will follow that
each tooth of either the top or bottom gear will represent one row or layer of thread
on the spool or bobbin & in such a case it is possible under ordinary circumstances to
put the intermediate in gear with the bottom gear at the wrong tooth, & thereby
stop the machine at the wrong end of the spool. This I prevent by forming on the
cheek of the spur pinion R a shroud or flange-covering half the depth of the teeth
and notched out at each alternate tooth, so that when the intermediate has each
alternate tooth cut to suit they can only enter at every second tooth as seen
in Fig. 6.
To ensure the completion of the building up of the bobbins at the outer end I
alter the ordinary stop motion to a suitable arrangement as illustrated in Figs. 4 & 5.
This consists of a spindle W having at its outer end and secured to it a disc or
head and provided at the outer end with a screwed extension w¹ to enable its.
being adjusted to any length within a moveable bracket or trigger X pivoted below
the guide holder Z this bracket X is provided with nipple & which in its normal
position hangs clear of the platform ¹ formed on the one end of the weighted

page_text: lever Z. Secured to the under side of the guide holder Z, is the usual finger a³,
which moves along the said spindle W, during the spooling operation, but when the
bobbin becomes suitably filled with thread the said finger engages the disc W
thereby tilting or depressing it, which motion is communicated through the
bracket X in such a manner and to such extent as to cause the rear end of the
weighted lever Z to disengage the bar bringing into operation the stop motion of
the machine.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is-
First. In spooling machines the arrangement and combination of parts constituting
the improved automatic shaping mechanism, whereby the same is capable of being
adjusted & adapted to wind thread on spools or bobbins of any required bevel or
size and to lay any required number of rows or layers of thread on such spools or
bobbins substantially as described and illustrated in Figs. 1, 2 & 3 of the drawings.
Second. In spooling machines the arrangements and combination of parts cou-
stituting the automatic stop arrangement, to ensure the completion of the building
up of the spool, or bobbin at the outer end, substantially as described and illustrated
in Figs. 4 & 5 of the drawings.
