page_text: I, JAMES BALDERSTON of Annfield Place, Paisley, in the County of Renfrew,
North Britain, Mill Manager do hereby declare the nature of the said invention
for IMPROVEMENTS IN SPOOLING MACHINES 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, and
has reference more particularly to that part commonly called the "builder
"shaper."

or
The Invention consists in constructing the "builder" or "shaper" in such
manner that it may be adjusted to "build" up the thread upon bobbins of any
bevil or size, and to be adjusted to "build up" any required number of rows or
layers of thread.
"
Hitherto, in changing from one bevil or size to another such bevil or size of
bobbin, upon machines known as the "Conant" spooling machines, it has been
necessary to remove the "builder" or shaper" and substitute for the one so
removed a "builder" or "shaper," the teeth of which are of a graduated length
corresponding to the particular bevil and of a number corresponding to half the
particular number of rows or layers of thread required.
"
Under the present improvements, the teeth of the "builder " or shaper' are
capable of being adjusted to any required length or bevil and the teeth so adjusted
may be employed in any number corresponding to half the number of rows or
layers of thread required upon the bobbins. The teeth are formed in two parts
and are fixed in plates which are adjustable by screws or otherwise upon another
plate. This last mentioned plate works vertically in guides and is constructed at
its back with a toothed rack, the teeth of which are in gear with a pinion. This
pinion is secured to the shaft which carries at one end the cam of the stop motion as
hitherto used and generally known as the "building" cam, and at the other end of
this shaft a wheel and counter-weight or their equivalents, are arranged to neutralize
the weight of the plate and its attachments. The chain supporting this counter-
weight is provided with a screw for adjusting the limit to which the plate and its
attachments are allowed to drop when the attendant removes the full bobbin, at
which time the "builder" or "shaper" is, for this purpose, thrown out of gear by

the bobbins off and on the arbor. A check is provided to prevent the teeth of the
builder" or "shaper" falling out of gear, and the said check is arranged to
operate in conjunction with the beforementioned lever.
"
In order to stop the machine after any required number of rows or layers of a
thread have been laid, the "building" can is turned upon its shaft and secured by
a screw or otherwise in such a position as will allow of the stop-motion taking
effect at the required time.

page_text: I, JAMES BALDERSTON, of Annfield Place, Paisley, in the County of Renfrew,
North Britain, Mill Manager do hereby declare the nature of my said invention for
IMPROVEMENTS IN SPOOLING MACHINES and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:

"
My Invention, which relates to improvements in spooling machines, is specially
applicable to the class of machines known as the "conant" spooling machines, and
has reference more particularly to that part commonly called the builder" or
shaper."
"
t
My invention consists in constructing the "builder" or shaper" in such
manner that it may be adjusted to "build" up the thread upon bobbins of any
bevil or size, and to be adjusted to " build up" any required number of rows or
layers of thread thereon.
Hitherto, in adjusting the spooling machine to wind thread upon bobbins or
spools of different bevils and of different dimensions, it has been necessary to
remove the "builder " $6
or shaper" and substitute for the one so removed a
builder" or "shaper" the teeth of which are of a graduated length corresponding
to the particular bevil and of a number corresponding to half the particular number
of rows or layers of thread required, that is to say, which are laid or wound upon
the bobbin.
Under the present improvements, the teeth of the "builder" or "shaper" are
capable of being adjusted to any required length or bevil and the teeth so adjusted
may be employed in any number corresponding to half the number of rows or
layers of thread required upon the bobbins.-The teeth are forined in two parts
and are fixed in plates which are adjustable by screws or otherwise upon another
plate. This last-mentioned plate works vertically in guides and is constructed at
its back with a toothed rack, the teeth of which are in gear with a pinion. This
pinion is secured to the shaft which carries at one end the can of the stop motion
as hitherto used and generally known as the "building" cam and at the other end
of this shaft a wheel and counter-weight or their equivalents are arranged to
neutralize the weight of the plate and its attachments. The chain supporting this
counter-weight is provided with a screw for adjusting the limit to which the plate
and its attachments are allowed to drop when the attendant removes the full bobbin
at which time the "builder or "shaper" is for this purpose thrown out of gear
by means of connections with the hand lever which lever has hitherto been used
for putting the bobbins off and on the arbor.-A check is provided to prevent the
teeth of the " builder or "shaper" falling out of gear, and the said check is
arranged to operate in conjunction with the beforementioned lever.
"
"
In order to stop the machine after any required number of rows or layers of
thread have been laid, the "building" cam is turned upon its shaft and secured by
a screw or otherwise in such a position as will allow of the stop-motion taking.
effect at the required time.

page_text: In order that my said Invention may be properly understood and readily carried
into effect, I will now proceed to describe the Drawings hereunto annexed.
Figures 1, 2 and 3 (Sheet 1) are respectively a front elevation, a back elevation
and a plan of a builder or shaper as constructed in accordance with my present
Invention.
Figure 4 (Sheet 2) is a side elevation of the same.
Figure 5 is a plan of part of, a spooling machine having the improved builder
or shaper (Figures 1 to 4) attached.
Figure 6 is a part side elevation of the same.
Figure 7 and 8 are views of detached portions of the said builder or shaper and
hereinafter more particularly described.
My improved "builder " or "shaper" is constructed with the teeth a, each of
which is formed of a separate plate of steel preferably of the shape represented in
plan at Figure 7, that is to say, with a dove-tailed projection b, extending from its
back. The projections b, fit into dove-tailed grooves in the longitudinal ribs or
raised portions c, (Figures 3 and 4) of the plates d, and between each of the teeth-
plates is arranged a distance piece e, which is also of a correspondingly dove-tailed
shape, as shewn more particularly in plan at Figures 3 and 8. All the teeth a, and
distance pieces e, are held firmly and closely together by means of the end plates f,
and studs g, the latter of which are screwed into the transverse projections h, of
the plates. These plates d, are slotted at, to admit of their free transverse or
horizontal motion upon the bolts i, when the nuts j, on the same are loosened.
When these nuts j, are tightened or screwed up, the plates d, are secured firmly
upon the front of the plate . The plates d, are each provided with the screwed
pillars or nuts, which are pivoted thereinto, and the plate k, has the forked
brackets m, also pivoted thereinto.-By means of the screws n, which screw into
the pivoted nuts 1, and the collars o, of which engage with forked brackets m, the
plates d, and the teeth a, attached thereto may be adjusted to any required position.
The plate k, is capable of working vertically in the guides p, which are formed in
part with the bracket q, and at its back the said plate k, is constructed with the
toothed rack, which gears with the pinion s. This toothed pinion 8, is secured
upon the shaft t, which is supported in the bracket q, in which it is prevented from
moving longitudinally by means of the collars 2. At one end the shaft t, is
provided with the cam u, similar to that described in the Complete Specification
filed in pursuance of Letters Patent granted to Hezekiah Conant No 2452 A. D. 1864
and shewn on the drawings annexed thereto.-The shaft t, is also furnished at this
and with the hand wheel v, and at its opposite end the said shaft is provided with
the wheel or sheave pulley w, to which one end of the chain x is secured.-From the
other or lower end of the chain x, is suspended the counter weight y, (Figure 4)
the position of which is adjustable by the nuts z, upon the screwed eye-bolt a¹, so
that the said counter weight y, which hangs below the .table or framing of the
machine, comes up against the underside thereof after any pre-adjusted amount of
upward travel. By these means the fall of the plate k, is also adjusted so that any
particular tooth a, may be arranged to come opposite to the lips b¹, (Figures 5 and 6)
and cause one of the two segmental nuts c', to engage with the right-and-left-
handed screwed shaft d', for the required period of time as and for the purposes
described in the aforementioned Complete Specification of Hezekiah Conant
No 2452 A.D. 1864. The bracket g, is pivoted between centres e¹, (Figure 6)
which engage with the conical recesses f¹, (Figures 1, 2 and 4) at either side
thereof, and the centres e¹, which are made adjustable are supported in the
brackets g, secured to the table or framing of the machine.-At one side of the
guides p, there is provided the arm h', which carries the bowl, which is engaged
with by the oblique slot j¹, of the lever k¹, (Figure 5). This lever ', is pivoted
at, to the framing of the machine and at its opposite end is connected by the
pivoted eye m', or its equivalent to the rod n¹. The rod n, is arranged to operate
in conjunction with the pivoted hand lever the handle of which is represented in
plan at o¹, Figure 5 and which, as described in the hereinbefore mentioned Complete

page_text: Specification, is employed for putting the bobbins off and on the arbor.-The
check p', is secured to the framing of the machine and is arranged to engage with
projections (not represented upon the annexed drawings) so arranged on the under-
side of the rod n¹, as to retain the teeth a of the "builder" either in a position
engaged with or disengaged from the lips b', the radial motion of a fixed stud in
the lever o¹, being sufficient to disengage the projections from the check pl, when
necessary. To prevent the point of the cam u, striking against the bowl q', of the
lever, of the presser thread guide (described in the aforesaid Complete Speci-
fication of Hezekiah Conant) when the teeth a, have been thrown back out of
reach of the lips 1, the bracket s¹, is secured to the adjacent side of the guide p,
so that the lever r' is supported thereon at the time the plate k, and its attachments
are descending.
In order to prevent the plate k, from falling out of the guides p, when the
"builder" or " shaper" is, for repairs or for other purposes removed from the
machine, or when the counter weight y, is removed, leather straps, one of which is
represented at t¹, (Figure 4) or their equivalents are secured, their lower ends upon
the lower of the bolts i, and their upper ends upon the bolts u¹, which are screwed
into the bracket q, and to prevent the said plate from being withdrawn upwards
out of the guides p, the forked piece v¹, or its equivalent is secured to the lower
part of the said plate so that the teeth of the pinion s, cannot pass over the
horizontal member of the said fork. Should it be desired to stop the machine after
any required number of rows or layers of thread have been laid, the "building"
cam u, is turned upon the shaft t, and secured by the screw w¹, or otherwise, in
such a position as will allow the bowl q, and lever ", (Figures 5 and 6) to fall,
and in the manner described in the aforementioned Specification of Hezekiah
Conant to operate the stop motion at the required time.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
First. The improvements in spooling machines consisting of the arrangement and
combination of parts constituting the "builder" or "shaper" whereby the same is
capable of being adjusted to wind thread on spools or bobbins of any bevil or size
and to lay any number of rows or layers of thread on such spools or bobbins all
substantially as and operating in the manner hereinbefore set forth with reference
to the annexed drawings.
Second. In "builders" or "shapers" of spooling machines the arrangement of
the teeth a, in two vertical sections carried in plates d, which may be adjusted
nearer to or further from each other either parallel or obliquely all substantially
as and for the purposes herein before set forth with reference to the annexed
drawings.
Third. The obliquely slotted lever k, pivoted at 1, and connected with the rod n³,
all arranged to operate in conjunction with the hand lever o', and to be engaged
with and disengaged from the check p¹, all substantially as and for the purposes
herein before set forth with reference more particularly to Figure 5 of the annexed
drawings.
