PROVISIONAL SPECIFICATION left by the said John Bullough, Joseph Smalley,
and Samuel Tweedale at the Office of the Commissioners of Patents on the 5th

⚫ STOP MOTIONS' APPLICABLE TO MACHINERY FOR PREPARING COTTON AND OTHER
FIBRES."
This Invention relates to further improvements in electric stop motions for which
Letters Patent were granted to John Bullough and Joseph Smalley, of Accrington
aforesaid, dated the Twenty-sixth day of August, in the year of our Lord One
thousand eight hundred and seventy-five, No. 3002.
The object of this Invention is as relating to spinning, intermediate, and roving
and similar machines, to ensure better contact between the parts representing
respectively the negative and positive poles of the battery or electric machine, and to
render the operation of "piecing up more convenient.
"
The Invention in its bearing on the carding engine and similar machines has
for its object the ensuring the requisite length of sliver for piecing up after
breakage.
In lieu of top rollers we employ a metallic guide and pass the thread between the
said guide and roller. The guide is mounted on a light blade spring, the tendency of
which is to bring the guide and roller into contact with each other, and so complete
the circuit of electricity and stop the machine. The presence of the thread when
not broken prevents this contact, and so prevents the circuit for the passage of the
electric current being completed, and the machine continues working. The guide

page_text: or eye is of circular form, with an open slit to facilitate threading, and a single guide
or eye may be mounted on each blade spring, or two eyes or guides may be mounted
on one and the same blade spring. Or in lieu of the spring a weighted lever may
be employed for securing contact when the thread is broken, such levers to be formed
with a similar guide or eye for the thread as already described.
To give off the requisite length of sliver for piecing up on machines, such as the
carding engine, we employ a ratchet wheel, operated by catch and rod, connected with
an eccentric on the card box shaft, giving a partial turn to a cam, the latter moving
a metallic connector, whereon the callender roller becomes charged, and if the sliver
is absent the circuit is completed, and the machine stopped by means of a rocking
lever working on a clip or open fulcram, that on the sliver breaking the magnet
having thereby become charged acts, bringing a second lever into position to act as
fulcram for the rocking lever, the latter now through the continued motion of the
eccentric knocks off the gearing lever.
Another arrangement for a like purpose comprises an insulated worm formed on
or secured to the boss of the doffer wheel, the end of a spring lever being forced
down on the worm when the disengaging lever drops, and is traversed thereby to
the other end thereof, when the said lever is raised or lifted out of the worm by
means of an incline at the end of the worm. The spring lever when so lifted clear
of the worm rebounds to the opposite end of the same, and there comes in contact
with a washer or flange formed or fastened to the end of the doffer shaft.
It is obvious that the spring lever and the flange or washer represent one pole of
the battery, and till contact takes place between them by the rebounding of the
spring lever no electrical action can take place, and as some time must elapse to
traverse the length of the insulated worm, a sufficient length of sliver has been
delivered meanwhile to enable the piecing up to be performed. Until this contact
of lever and flange takes places no action of the magnet can take place, as the
circuit is interrupted, and before the time the circuit is completed by their contact
sufficient sliver has been given out by the engine to enable the " tenter" to piece up,
and when such piecing up has taken place there is cotton between the two small
callender rollers which represent the two opposite poles of the battery, and therefore
the circuit is again interrupted at this point, and the engine goes on working only
when a new breakage of the sliver takes place, and these callender rollers come in
contact and momentarily complete the circuit, and cause the doffer lever to be
disengaged, and in dropping it brings the end of the spring lever down on the
insulated worm, and in the way described keeps the circuit broken till sufficient
aliver has been delivered to enable the piecing up to be performed.
The spring lever when lifted out of the worm by the incline or projection spoken
of tends to fall or tip over still further clear of the worm till arrested by a stop
piece. This stop piece may be made to serve the same purpose as the washer or
flange.
We may here say that as some parties object to having the doffer stopped on the
breakage of sliver, we propose to merely ring a bell on such breakage occurring, and
to leave the doffer motion as usual. This may be done by the ordinary electric bell, or
by causing the action of the magnet to bring into position certain parts of mechanism
which will cause a bell to be rung by mechanical means.

This Invention relates to further improvements in electric stop motions for which
Letters Patent were granted to John Bullough and Joseph Smalley, of Accrington
aforesaid, dated the 26th day of August, A.D. 1875, and numbered 3002.
The object of this Invention is as relating to slubbing, intermediate, and roving
and similar machines, to ensure better contact between the parts representing
respectively the negative and positive poles of the battery or electric machine, and
to render the operation of piecing up more convenient.
The Invention in its bearing on the carding engine and similar machines has
for its object the ensuring the requisite length of sliver for piecing up after
breakage.
In lieu of top rollers we employ a metallic guide, and pass the thread or fibre
between the said guide and roller. The guide is mounted on a light blade spring,
the tendency of which is to bring the guide and roller into contact with each other
and so complete the circuit of electricity, and stop the machine. The presence of
the thread or fibre when not broken prevents this contact, and so prevents the
circuit for the passage of the electric current being completed, and the machine
continues working. The guide or eye is of circular form with an open slit to facilitate
threading, and a single guide or eye may be mounted on each blade spring, or two
eyes or guides may be mounted on one and the same blade spring. Or in lieu of the
spring a weighted lever may be employed for securing contact when the thread is
broken, such levers to be formed with a similar guide or eye for the thread as already
described.
To give off the requisite length of sliver for "piecing up" on machines, such as
the carding engine, we employ an insulated worm formed on or secured to the boss
of the doffer wheel, the end of a spring lever being forced down on the worm
(when the disengaging lever drops), and is traversed thereby to the other end of the
worm, when the said spring lever is raised or lifted out of the worn by means of an
incline at the end of the worm. The spring lever when so lifted clear of the worm
rebounds to the opposite end of the worm, and there comes in contact with a washer
or flange formed or fastened to the end of the doffer shaft.
"
The spring lever and the flange or washer represent one pole of the battery, and
until contact takes place between them by the rebounding of the spring lever no
electrical action can take place, and as some time must elapse to traverse the length
of the insulated worm, a sufficient length of sliver has been deliverd to enable the
'piecing up" to be performed. Until this contact of lover and flange takes place
no action of the magnet can take place, as the circuit is interrupted; and before the
time the circuit is completed by their contact, sufficient sliver has been given out by
the engine to enable the "tenter" to piece up; and when such piecing up has taken
place, there is fibre between the two small calender rollers which represent the two
opposite poles of the battery, and therefore the circuit is again interrupted at this
point, and the engine goes on working until a new breakage of the sliver
takes place, and the calender rollers come in contact and momentarily complete the
circuit and cause the doffer lever to be disengaged, and in dropping it brings the end
of the spring lever down on the insulated worm in the way described, keeping the
circuit broken till sufficient sliver has been delivered to enable the "piecing up" to
be performed.
We may here say that as some parties object to having the doffer stopped on the

page_text: breakage of sliver, we propose to merely ring a bell on such breakage occurring, and
to leave the doffer in motion as usual. This may be done by the ordinary electric
bell, or by causing the action of the magnet to bring into position certain parts of
mechanism which will cause a bell to be rung by mechanical means.
Such being the nature and object of this our Invention, we will proceed to describe
the same in detail, and have annexed five Sheets of Drawings of which the following
is a full description.
Figs. 1, 2, and 3, Sheet 1, shew the Invention connected with slubbing, inter-
mediate, roving, and similar machines.
In lieu of the top rollers we employ a metallic guide A and pass the thread or
fibre B between the said guide and roller C. The guide is mounted on a light blade
spring D, the tendency of which is to bring the guide A and roller C into contact
with each other, and so complete the circuit of electricity and stop the machine.
The presence of the thread or fibre B when not broken prevents this contact, and
so prevents the circuit for the passage of the electric current being completed, and
the machine continues working. The guide or eye A is of circular form with an
open slit to facilitate threading, and a single guide or eye may be mounted on each
blade spring, or two eyes or guides may be mounted on one and the same blade
spring (see Fig. 3). Or in lieu of the spring a weighted lever E (see Figs. 4 and 5)
may be employed for securing contact when the thread is broken, such levers E to
be formed with a similar guide or eye for the thread as already described.
Figs. 6, 7, and 8, shew stop motion for intermediate frame. A is the magnet
which, when charged by contact (of roller or rollers and guide as described), attracts
the lever B, so taking gear on the catch wheel C; the continued rotation of the
wheel C draws the lever D (carrying B) forward, and pushing the stop rod E and
transferring the strap to the loom pulley. At Fig. 8 the catch B is mounted upon
the stop rod E, and lever D receives its rocking motion from the stud F in slot G
formed on lever D.
In connection with the carding engine, Figs. 9 and 10, to give off the requisite
length of sliver for "piecing up," we employ an insulated worm A formed on or
secured to the boss of the doffer wheel B, the end of a spring lever C being forced
down on the worm A by rod a (when the disengaging lever D drops), and the said
lever C is traversed thereby to the other end of the worm A, when the said spring
lever C is raised or lifted out of the worm A by means of an incline E at the end of
the worm A. The spring lever C when so lifted clear of the worm A rebounds to
the opposite end of the worm, and there comes in contact with a washer or flange F
formed or fastened to the end of the doffer shaft G.
"
The spring lever C and the flange or washer F represent one pole of the battery,
and until contact takes place between them by the rebounding of the spring lever C,
no electrical action can take place, and as some time must elapse to traverse the
length of the insulated worm a sufficient length of sliver has been delivered to enable
the "piecing up to be performed. Until this contact of lever and flange occurs no
action of the magnet can take place, although the calender rollers in coiler ure in
contact as the circuit is interrupted, and before the time the circuit is completed by
contact of lever C and washer F, sufficient sliver has been given out by the engine to
enable the "tenter" to piece up, and when such "piecing up" has taken place there
is fibre between the two small calender rollers which represent the two opposite
poles of the battery, and therefore the circuit is again interrupted at this point, and
the engine goes on working until a new breakage of the sliver takes place, and the
calender rollers come in contact and momentarily complete the circuit, and cause the
doffer lever to be disengaged, and in dropping it brings the end of the spring lever C
down on the insulated worm A in the way described, keeping the circuit broken
until sufficient sliver has been delivered to enable the "piecing up " to be performed.
The spring lever C when lifted out of the insulated worm A by the incline E forces
the pendant finger H to the other side of the incline K on the spring L, so holding
the spring lever C clear of the insulated worm A until another breakage of fibre
takes place. The parts C and L are insulated from rod a and brackets M and N.

page_text: Figs. 11 and 12 shew the action of the magnet to bring into position certain parts
of mechanism which will cause a bell to be rung by mechanical means. A is the
coiler shaft; B, an eccentric acting on bowl C on lever D, thus giving motion to the
lever D, the return motion to D being by spring W. When the fibre is absent from
between the two calender rollers in the coiler the circuit is complete, and the magnet E
draws the lever F, the other end F' of which is caught by catch d on lever D, the
continued motion of D moves the part G forward, and as the bell H is carried thereon
the bell is then within reach of the hammer h, the slide part G being held in the
forward position by the catch or notch K and part L, and so the bell continues to
ring until the operative "pieces up" and removes the part G from the notches K
and L, whereon the spiral spring M returns the part G to the original position.
Having thus fully described the nature and particulars of this our said Invention,
together with the manner in which the same is to be or may be performed or carried
into practical effect, we would have it understood that we limit our claims to,---
The spring or weighted guide eye or eyes A, as and for the purpose described and
illustrated.
The combination of the insulated worm A and the spring lever C, as and for the
purpose herein described and illustrated.
In witness whereof, we, the said Joseph Smalley and Samuel Tweedale, for and
on behalf of ourselves and the said John Bullough, have hereunto set our
hands and seals, this Second day of March, in the year of our Lord One
thousand eight hundred and seventy-eight.
