of Paper or like Materials.
We JOSEPH BRIGGS SWAILES, GEORGE SWALLES and JOHN BROADMEADOW
SWAILES, of the firm of John Swailes & Sons of Moorhey, Oldham, in the County of
Lancaster, Cop tube Manufacturers and Machinists, do hereby declare the nature of
the said invention, to be as follows:-
Our invention is applicable to well known selfacting machines for making cop tubes
from paper or like materials, in which paper is drawn from a reel is pasted, cut into
the sizes required for the cop tube or tubes, rolled up on a spindle or spindles, and is
then discharged from the spindle or spindles completed.
The object of our invention is to stop the machine when the paper breaks or fails,
and also to stop it when the lengths cut from the web of paper fail to be rolled or
formed upon the spindle or spindles we thus by our improvements save time and
prevent the waste of paper.
::
Our invention may be carried into effect by a variety of arrangements. To stop
the machine when the web of paper breaks or comes to an end, we arrange the web
of paper to pass against projections or supporting surfaces, and on the opposite side
of the paper have a lever or feeler" so balanced as to be easily kept in position by the
" fceler
paper when the web is present and is passing, but when absent this lever or
is allowed to fall, and in falling overbalances another lever which strikes against a
lever, or other mechanism with such force as to give motion to it to release the
slide of the belt guide and allow it to traverse the driving strap on to the loose
pulley.
«
Instead of the feeler lever" falling against another lever, it may be arranged
when it ceases to be sustained by the passing paper web, to come in the way of
oscillating or rotating mechanism, which will act to release the belt slide from its
notch and allow a spring or weight to move it and thus stop the machine.
The mechanism to stop the machine when the pieces of paper cut from the web
cease to be wound upon the spindle is as follows.
The slips of paper go over a surface when passing to the winding spindle, but if
they fail to be wound or rolled upon the spindle they remain upon or over the said
surface.

page_text: A "feeling lever" is arranged to work to and fro by means of a cam upon a shaft
gearing with the winding spindle, and the end of this "feeling lever" is actuated and
timed so that its end comes down upon the slip of paper-(if present by not having
been wound upon the spindle) and as the "feeling lever" is only brought down by a
spring it is sustained by the presence of the slip of paper, but if the slip has been
wound upon the spindle then the end of the feeling lever is not sustained and its
other end can then act to oscillate a small lever on a vertical slide, so that this small
lever will not be acted upon by the end of a lever oscillated by a cam on a shaft
making one revolution for each tube made, but if the end of the feeler lever is sustained
by the presence of a slip which has not been rolled up, then the small lever is not
acted upon by the other end of the feeler lever, and the cam lever can come against it
and lift the small lever and thus the slide upon which its fulcrum is jointed, this slide
lifting the belt guide slide rod out of its notch allowing the belt to be guided on to
the loose belt pulley.
Instead of the arrangement last described, the said small lever on the vertical slide
or its equivalent is or may be connected with a lever or part pressing the paper when
being rolled or wound upon the spindle against it, so that when this pressing lever or
part is not moved by a failure in winding a slip of paper upon the spindle it will allow
the said small lever or its equivalent to remain in the position to be acted upon to stop
the machine as hereinbefore explained.
The withdrawing of the tube spindle from the tube is or may also be made to act
upon a fecler lever connected with the small lever or its equivalent such feeler lever
being thus acted upon when a tube is discharged from the spindle but will remain
stationary when a tube is not discharged, and will thus cause the small lever or its
equivalent to be acted upon to stop the machine as hereinbefore explained.
Instead of the mechanism above described, we also use a current of electricity from
any convenient source arranged to pass through elastic or other feelers between which
the web of paper passes and which while present (the web being a non conductor)
prevents the current passing, but when absent allows contact between the feeler and
another conducting surface connected with a small electro magnet which acts upon a
releasing catch or acts upon a catch to bring it in the way of a vibratory or rotating
part that operates upon the releasing catch or equivalent mechanism.
Instead of the paper web keeping the feeler and conductor apart the feeler is or
may be balanced and sustained by the paper and when not sustained by the paper it
falls into contact with the conductor or other contact piece, and then allows the current
to pass to the electro magnet.
In the case of the slips of paper which fail to be rolled then it is the presence of
the slip after the time when ought to be rolled that is, the operating cause which
stops the machine.
One end of a feeler lever is arranged and actuated by a cam or otherwise to come
upon the slip of paper, if it is left unrolled, and cause the other end of the feeler lever
to make contact with a conductor to an electro magnet.
The cam action brings one end of the said feeler lever to operate when the slip will
have been withdrawn away if duly rolled, so that if the slip has been duly rolled,
there is nothing left to sustain that end of the feeler lever and cause its other end to
make electric contact.

of the firm of John Swailes & Sons of Moorhey, Oldham in the County of Lancaster,
Cop tube Manufacturers and Machinists, 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 :-
Our invention is applicable to well known self-acting machines for making cop
tubes from paper or like materials, in which paper is drawn from a reel, is pasted,
cut into the sizes required for the cop tube or tubes, rolled up on a spindle or spindles
and is then discharged from the spindle or spindles completed.

and also to stop it when the lengths cut from the web of paper fail to be rolled or
formed upon the spindle or spindles we thus by our improvements save time and
prevent the waste of paper.
دو
Our invention may be carried into effect by a variety of arrangements. To stop
the machine when the web of paper breaks or comes to an end, we arrange the web
of paper to pass against projections or supporting surfaces, and on the opposite side
of the paper have a lever or "feeler so balanced as to be easily kept in position by
the paper when the web is present and is passing, but when absent this lever or
"feeler" is allowed to fall, and in falling overbalances another lever which strikes
against a lever or other mechanism with such force as to give motion to it to release
the slide of the belt guide and allow it to traverse the driving strap on to the
loose pulley.
Instead of the "feeler lever" falling against another lever, it may be arranged
when it ceases to be sustained by the passing paper web, to come in the way of
oscillating or rotating mechanism, which will act to release the belt slide from its
notch and allow a spring or weight to move it, and thus stop the machine.
The mechanism to stop the machine when the pieces of paper cut from the web
cease to be wound upon the spindle is or may be as follows.
The slips of paper go over a surface when passing to the winding spindle, but if
they fail to be wound or rolled upon the spindle they remain upon or over the said
surface.
23
A feeling lever is arranged to work to and fro by means of a cam upon a shaft
gearing with the winding spindle, and the end of this "feeling lever is actuated and
fimed so that its end comes down upon the slip of paper (if present by not having

page_text: been wound upon the spindle) and as the "feeling lever" is only brought down by a
spring it is sustained by the presence of the slip of paper, but if the slip has been
wound upon the spindle then the end of the feeling lever is not sustained and its
other end can then act to oscillate a small lever on a vertical slide, so that this small
lever will not be acted upon by the end of a lever oscillated by a cam on a shaft
making one revolution for each tube made, but if the end of the feeler lever is
sustained by the presence of a slip which has not been rolled up, then the small lever
is not acted upon by the other end of the feeler lever, and the cam lever can come
against it and lift the small lever and thus the slide upon which its fulcrum is jointed,
this slide lifting the belt guide slide rod out of its notch allowing the belt to be guided
on to the loose belt pulley.
Other modes of carrying out our invention are or may be used which will be
hereinafter described by reference to drawings.
Fig. 1 is a front elevation of so much of the parts of cop tube making mechanism
as will be necessary for explaining the application of our invention thereto.
Fig. 2 is a plan view of some of the parts shown in fig. 1 and of other parts not
shown therein.
Fig. 3 is a cross sectional elevation in or about the line A-B fig. 1 looking towards
the driving end of the machine.
Fig. 4 is an elevation at a right angle to the plane of the elevation fig. 1 of parts
of the mechanism for stopping the machine when the web of paper breaks or fails
the parts being shown in the position they occupy when the web of paper is present
and all right.
Fig. 5 shows the parts represented in fig. 4. but in the position they occupy when
the web of paper has broken or failed.
a will represent the top or bed part of the machine, the first motion shaft (its
bearings are omitted) upon which are the fast and loose driving pulleys b¹ and b² for
the driving belt 63 to work upon.
a and a² are two stands secured to the bed a in which slots are formed for a bar c
to slide in, which bar c has two studs or prongs c¹ projecting from one side of it,
which act to guide the belt from the fast to the loose pulley or vice versa.
The slide bar c has a notch c² on its under edge, seen best in fig. 3, which notch in
the bar e when in the position with the belt on the fast driving pulley comes on each
side of the stand a¹ and resists the pull of the helical spring secured to a pin on the
stand a' at one end and to a pin in the slide bar c at the other end, this spring of
having force sufficient to slide the belt from the fast to the loose pulley when the
bar c is lifted at the belt fork end to release the notch in it from the stand a'.
In fig. 3 the bar c is shown in the position in which the belt is on the loose
pulley and with the stop pin c in the bar c against the side of the stand a².
The first motion shaft 6 drives by bevel wheels, indicated by dotted line, a shaft d
in the lengthway of the bed and this shaft d has the cams upon it for operating some
of the ordinary mechanism of the machine and the shaft by bevel wheels also
rotates another shaft p¹ which also gives rotation at intervals to the spindle e upon the
ende of which the slips of paper are wound which form the tube.
This spindle e can rotate in bearings and also slide endways therein, being moved
endways by a cam on the first motion shaft b and by means of a lever and spring
not shown, and the tube when formed is stripped from the spindle e¹ when drawn back
through the eye in the part secured to the framing.
and gl are rollers which draw the web of paper from the reel (not shown) which
web is represented by the line a fig. 1 and the rollers g¹ feed it to the shears which
cut so much from the end of the web as will when rolled up form one tube.
The paste is applied to one side and edge of the web when it arrives at the rollers
as is well understood.
h in fig. 1 represents in section the fixed cutting jaw of the shears which cut the
slips from the end of the web, as is well understood; a slip a sufficient for one tube
being shown detached from the web in fig. 1.

page_text: It will be understood that the width of the web of paper is equal to the length of
the slip of paper to be wound up to form the tube, and the length, cut from the web
corresponds with and forms the lengthway of the tube when rolled.
Before the slip of paper el is cut from the web it comes between nipping surfaces
on two jaws or levers i and shown in fig. 2 and partly in fig. 1.
These nipper levers and have their fulcrum 2 on a bracket a³ and they are
actuated by cams and springs (not shown) and they operate to pinch the slip cut from
the web and carry it to the level of and present it to the spindle e' upon which it is
to be wound to form the tube as is well understood.
All the parts hitherio referred to by letters of reference (except the slide c and
connected parts) are ordinary and known parts of machinery for making cop tubes,
and they operate in the ordinary manner and the ordinary parts not shown in figs. 1
to 5 are omitted in order that the other parts may be more clearly represented.
The mode of stopping the machine when the paper web fails or breaks will be first
described. a is a bracket or stand secured to the bed a and to it an adjustable bracket j
is secured having two prongs or pins which come under and sustain the web
of paper passing over them.
On a fulcrum carried on the stand at a bell-crank or two armed lever is
mounted the horizontal arm having a roller 2 free upon it which rests upon the
upper surface of the web when present, but when absent will pass between the two
pins or prongs This bell-crank lever k is lightly balanced by an adjustable weight k³
upon the vertical arm so that the horizontal arm tends to descend, if not sustained by
the passing web.
On the same fulcrum with the bell crank lever there is another or tumbler weight
lever which rests just sufficiently back against the stand at, as shown in figs. 4 and 5,
as not to fall forward unless first moved in that direction.
When the bell-crank lever k begins to fall its weight, after it begins to move and its
velocity is sufficient to overbalance the tumbler-lever forward, a projection from the
lever coming against the tumbler lever, so that both bell-crank and tumbler-lever
fall into the position shown in dotted line in fig. 5.
The weight of the tumbler-lever falls and rests upon a projection 12 from a lever /
on a fulcrum on a bracket a secured to the bed of the machine.
This lever is counterbalanced by an adjustable weight 13 upon one arm.
Both ends of the knocking off lever are bent upwards, and that end nearest the
first motion shaft & comes under the edge of the sliding bar c that when the tumbler
weight lever falls upon the projection upon one end of the lever it is over
balanced and the other end lifts the bar e and releases its notch from the stand a¹ and
thus stops the machine, as hereinbefore explained.
To stop the machine when a slip cut from the web fails to be rolled upon the spindle
will be next described.
A table m is formed over which one end of the slip of paper al will come when cut
from the web a this table is secured to and carried by the lower nipper jaw or lever i
herein before referred to and the table m has a hole in it through which the bent end
of a lever which we call the "feeling lever" can pass clear, when no slip of paper is
present.
This feeling lever is formed in two parts one part is adjustable and secured in a
boss part n¹ on a stud n² in the stand or bracket a' the other or tail part n³ of the
feeling lever is adjustable and is secured in like manner to the said fulcrum boss part n'
there is also a projecting arm n from the boss part seen in fig. 1 which comes against
and is acted upon by the face of a drum camp on the shaft pl in suitable bearings in
brackets or strands from the bed, this shaft p¹ being geared to the first motion b by
bevel wheels herein before referred to.
This camp causes the feeling lever n to oscillate and to bring the feeling end of
the lever down so as to be opposite the table m just after the tail of the slip to be
rolled has been withdrawn, when properly rolled and then to descend into the position
in which it is shown in dotted line in fig. 1, if no slip is present, but if the slip of

page_text: paper fails to be rolled or wound up, it remains upon the table and it prevents the
descent of the feeling end of the lever below the table, as the lever is only drawn down
by the helical spring n one end of which is secured to the lever n and the other end
to a pin on the stand aº.
When the feeling end of the lever n descends through the hole in the table m, as
shown in dotted line in fig. 1, its tail end n³ comes in contact with an arm from a
lever having its fulcrum at q¹ upon a part q² arranged to slide vertically in guide
ways from the stand a¹ the upper end of the slide coming under the slide bar c. This
action of the tail of the feeling lever 3 places the lever q in a position shown in
dotted line in fig. 3 in which its projecting tail is clear of the end of one arm of a
bell-crank lever ³, having its fulcrum on the stand a² the other arm of which
lever q is actuated by a cam 9° on the shaft d.
But when the feeling end of the lever n does not descend below the hole in the
table m by reason of the slip of paper having been left upon it unrolled, then the
lever is left in the position shown in full line in fig. 3 when the end of the bell-crank
lever will catch upon it and lift it and the slide q² to which it is attached until the
upper end of the slide comes under and lifts the bar c with its notch clear of the
stand a and thus stops the machine.
Another mode of carrying our invention into effect is illustrated by figs. 6, 7 and 8
which are views corresponding respectively to figs. 1, 2, and 3, fig. 8 being a section
at A-B fig. 6 looking towards the belt driving end of the machine.
The ordinary parts of the machine are arranged as hereinbefore described or as
hereinafter explained.
The mechanism for stopping the machine when the web of paper breaks or is absent
is the same as that hereinbefore described in reference to figs. 1 to 5, but the mechanism
for stopping the machine when the slipse cut from the web fail to be rolled upon the
spindles is different.
The feeler lever (n figs. 1 and 2) is mounted to work freely on the same stud or
fulcrum as that for the nipper levers i and and it is actuated by a camp on the
shaft d which cam acts upon a bowl on a stud in an arm n from the boss of the feeler
lever n which is made to descend by a spring as in figs. 1 and 2 or as otherwise
arranged.
When the slip of paper remains upon the table m instead of being rolled upon
the spindle e¹ the end of the feeler lever n is sustained above the hole in the table m
but when the slip al is absent in consequence of its having been properly rolled then
the end of the feeler lever n passes through the hole in the table m and comes upon and
depresses the horizontal arm of a bell-crank lever q having its fulcrum on a stud q¹
in a bracket 2 secured to the bed a.
The vertical descending arm of the bell crank lever 7 has a projection in which
there is an adjustable set screw q having a lock nut.
4
The vertical arm is pulled against a pin stop in the bracket carrying its fulcrum
by a spring q attached at one end to the bracket 2 and at the other end to the vertical
arm so that when the horizontal arm of the bell crank lever q is not acted upon (as
when a slip of paper has been left unrolled) the vertical arm of the lever y remains
in the position in which it is shown in fig. 6, with the point of the set screw q under 4
the bent end of a lever q³ having its fulcerum q on the lever 1.
There is or may be a stop to limit the movement of the lever g in both directions as
shown in fig. 6 or in any other convenient way.
The lever q is connected by an rod q³ with a cam or excentric 78 (the latter is
shown) on the first motion shaft b, which rotates in the direction pointed by the curved 5
arrow on fig. 6 so that the lever q³ is constantly oscillating up and down while the
machine is in motion, the bent end of the lever y³ being timed to descend just after
the time the bent end of the feeler lever » would arrive in its lowest position when
not intercepted by the slip of paper a¹ on the table consequently the end of the set
screw upon which the bent end of the lever q³ descends, becomes for the moment the 5
fulcrum and the ascent of that end of the lever q³ connected with the excentric rod q

page_text: lifts the fulcrum stud q' in the lever
guide slide bar c and stops the machine.
and thus the latter, and this releases the belt
When the slip of paper a¹ is absent the vertical arm of the bell-crank lever q moves
the set screw clear of the bent end of the lever q3 and this permits it to be oscillated
without producing any movement in the lever which is arranged to come to a stop
in any convenient position in one direction against which it is held by a spring
to prevent it from moving except when the set screws comes under the bent
end of the lever q³ to stop the machine.
Fig. 9 is a sectional elevation at a vertical line C-D fig. 6 looking from the
driving end of the machine, showing another modification in which the bell-crank
lever is placed with its fulcrum q in a line parallel with the lengthway of the
bed of the machine, the fulcrum being carried on a bracket secured to the bed a.
There is a stop pin and spring as explained in reference to figs. 6 and 8 to
bring the vertical arm of the lever q into the position shown in full line in fig. 9
when the slip of paper a sustains the feeler lever n but when the feeler lever
acts upon the horizontal arm of the bell-crank lever the vertical arm is moved
into the position shown by dotted line in fig. 9 with the set screw 7 clear of the
end of the lever 3 which in this case may be straight and need not have its end
bent as shown in figs. 6 and 8.
Instead of the sliding belt rod c, the ordinary belt fork lever is or may be used
combined with the lever the belt fork lever mechanism being modified in this
case as illustrated by fig. 10 (an elevation in the plane of that shown by fig. 6)
and by fig. 11 an elevation at a right angle to fig. 10, fig. 12 being the handle upper
end of the lever in the plane of fig. 11 which is shown detached from the lever
for want of space above figs. 10 and 11 on the drawing.
The prongs for the belt are shown in fig. 12.
The belt fork lever c is mounted as in the ordinary arrangement upon a fulcrum
stud in a bracket a' secured to the bed a.
One end of a flat spring c³ (a flat or other spring is or may be used) is secured to
the bracket a¹ the free end of the spring acting upon the edge of the lever c to move
it in the direction to traverse the driving belt from the fast to the loose pulley. There
is a stud or projection a' on the bracket a¹ which has a bent or hook finger as and
between the stud a' and bent finger as the end of the lever comes and can move
freely, the end of the lever being formed as shown in fig. 10.
There is a stud c² in the side of the belt fork levere which comes against the side
of the end of the lever (see fig. 11) in which position it holds the belt fork lever c
with the driving belt upon the fast pulley, but when that end of the lever nearest
the driving pulleys is lifted it enters the recess formed by the bent finger as and allows
the stud in the belt fork lever e to pass under it as the belt fork traverses the belt
from the fast to the loose pulley by the action of the spring c³.
When the belt fork lever c is moved to traverse the belt from the loose to the fast
pulley the end of the lever drops between the stud a' and that c² on the belt fork
lever c.
Another modification of mechanism for carrying out our invention is illustrated by
figs. 13 to 17 inclusive.
Fig. 13 is a longitudinal elevation, fig. 14 a plan, fig. 15 a cross sectional elevation
on the line C-D fig. 13 looking towards the driving end of the machine, fig. 16 is a
cross sectional elevation on the line A-B fig. 13 looking from the driving end of the
machine and fig. 17 is a cross sectional elevation on the line E-F fig. 13 looking
from the driving end of the machine.
Figs. 13 and 14 are views corresponding to figs. 1 and 2 except that fig. 13 shows
the opposite side of the machine to that shown in fig. 1, and the driving end of the
machine is consequently on the right of fig. 13 and 14, and on the left of figs. 1
and 2.
Only such parts of mechanism are shown in figs. 13 to 17 as are necessary for
explaining this modification of our invention:

page_text: d is the longitudinal cam shaft which has a drum cam qupon it acting upon a bowl
on a stud in the end of a lever 3 having its fulcrum q¹ on a stud in a bracket secured
to the bed (shown best in fig. 15.)
The reverse movement of the lever q³ is given by a helical spring q* secured to
the lever at one end and to the bed a at the other end.
The stud in the lever for the bowl also forms the fulcrum for a lover u a stud
on the lower end of which is jointed to a rod ² passing the lengthway of the machine,
this rod being also jointed to a stud at the lower end of each of two other levers v
and v¹.
The rod u² is made with slots as shown to be adjusted in length.
Upon the upper end of the lever u there is a stud 3 having a bowl upon it which
rests against the vertical arm of a bell-crank lever we having its fulcrum w¹ on the
stand a².
The horizontal arm of the bell crank lever w enters a notch in the belt fork bar c,
which horizontal arm has a weight upon it sufficient to keep the arm down in the
notch in the bar c and resist the oscillations in the upper end of the lever u when
there is no obstruction to the uiovement of the levers vand v', but when the move-
ments of these levers are obstructed, then the lower end of the lever u is held from
oscillating and its joint stud becomes the fulcrum upon which the upper end (u³) of
the lever oscillates which then moves to and fro with the fulcrum stud 11, and this
causes the horizontal arm of the bell crank lever w to be lifted out of the notch in the
bar e when the spring c³ slides the rod cand traverses the driving belt from the fast to
the loose pulley.
To stop the machine when the web of paper breaks or is absent there is a stand a²,
bracket and supporting studs as described in reference to figs. 1, 4 and 5. There
is also a lever & with a roller 2 on a fulcrum but this fulcrum is carried on the ends
of the studs.
The roller is supported upon the web a but when absent the roller falls between
the studs and a projection from its fulcrum or boss part acts to lift one end of a
balanced lever and depress the other end which is at other times held up.
This balanced lever is upon the same fulcrum as the lever k and its long end
descends vertically through a guide, bracket or stay a and a block or square piece k
on its lower end comes and slides freely against one side of a vertical projection a³
from the bracket carrying the fulcrum 2 of the lever v.
If the web a is absent the block end of the balanced lever is depressed to
come in the way and prevent oscillation in the lever v¹ and this stops the machine
as hereinbefore explained in reference to the levers eu and w.
The machine is stopped when a slip a fails to be rolled upon the spindle e', by a
feeler lever n, arranged as described in reference to figs. 6, 7 and 8 except that when
the end of the feeler lever n passes through the hole in the table m it does not act as
in figs. 6, 7 and 8 upon a lever q.
The feeler lever n is acted upon by a camp on the shaft & which works against a
bowl on a stud in the side of the feeler lever n or an arm from it.
There is an arm * hinged at n³ to a part n' secured to the boss n¹ of the feeler
lever n.
This arm n can oscillate one way but only to a given extent (being limited by a
stop or the form of the hinge, being made like a measuring rule joint) in the other
direction and there is a flat spring n one end of which is secured to the part n and
the other end acts upon the arm n to push it to its limit from the spring when
allowed to do so.
The cam which causes the oscillation in the levers and is formed and adjusted
to cause the upper ends of the levers v and v¹ to begin to oscillate in the direction from
the belt driving end of the machine just after the end of the feeling lever n has
passed to its lowest position through the hole in the table m, and this, when the slip
has been wound upon the spindle e will keep the arm n clear of the upper end of
the lever v but should the slip x¹ fail to be rolled the feeler lever n is sustained in

page_text: about the position shown in fig. 16 when the arm * will then be in the way of and
will prevent the oscillation of the lever on the fulcrum 3 and thus stop the machine
as hereinbefore explained.
The hinging of the arm n as described allows the feeler lever n to oscillate without
obstruction as the arm n* when on one side of the lever as shown in dotted line in
fig. 16 gives way and the spring n' brings it to the front of the lever v to prevent its
oscillation at the time required when the descent of the feeling lever n is arrested in
about the position shown in fig. 16 by the slip ¹ of unrolled paper.
It will be obvious that the arrangements for carrying out our invention may be
varied in details without departing from the main features of our invention.
Figs. 18 to 20 illustrate the mode of carrying out our invention by means of
electricity obtained from any convenient source.

an arm or lever the end of which presses the web upon the surface of the
stud by the torsional action of a coiled helical spring 3 one end of which is secured
in the collar of the stud k¹ and the other end rests upon the lever k².
The stud is insulated from the arm by washers of vulcanite wood or other
suitable insulating material k*.
A sufficient current of electricity from a dynamo or any other suitable source of
electricity passes along a connecting wire t, attached by binding screws in blocks
of wood, vulcanite or other suitable insulator secured to the bed a of the machine,
this wire being connected with the stud and passes to the lever ², but as long as
the paper web which is a non-conductor of electricity is between the lever k² and
stud the current is broken but when the web is broken the contact is made
between the lever k² and stud j¹ it then passes through the bed (a) to the electro
magnets formed in the ordinary manner, which electro-magnets are carried upon a
bracket a from the stand.
The studs for the electro magnets are insulated by vulcanite or other suitable
insulating washers u¹ from the bracket as and the electricity is conducted from the
bracket a by means of binding screws on the bracket for wires u² and from the coil
B

page_text: of insulated wire round the soft iron core of the magnet, and the electricity after
- passing the coils goes along wires to a binding screw for the conducting wires carried
from the bracket at by a piece of vulcanite or other insulating material and then
by a wire to one jaw u of two springs, and from one to the other jaw the
clasticity of the jaws bringing them in contact and from this second spring jaw u the
wire us carried in suitable insulators passes back to the electric generator.
When the current passes through the electro-magnet, a piece of soft iron is drawn
to the poles or cores, this soft piece of iron is secured to a lever ¹ of brass, hinged
to the stand a² at 2, the brass lever has a hook at its free end which takes hold of a
notch in the belt fork slide c, and holds it with the belt on the fast pulley b¹ but when
the electro-magnet operates the lever v' is lifted and its hook is thus released from
the notch and the spring e² slides the rod e to take the belt on the loose pulley 62.
To the slide e a plate of metal is secured carrying a piece of vulcanite or similar
insulating material 3 which is wedge shaped at one edge to come between the two
clastic jaws u and u' and separate them when the slide c is moved to pass the belt to
the loose pulley 2 this breaks the current and prevents its waste so that one dynamo
will do for several machines-The two elastic jaws and are secured to wood or
vulcanite attached to the stand a².
In the ordinary machine the presser which acts to press against the paper when
being wound upon the spindle e¹ is upon a bell-crank lever, mounted on a stud in a
stand a secured to the bed a-The pressing surface is mounted on one arm and the
other arm has a bowl on a stud in it which is acted upon by a cain d' on the shaft d―
this arm of the hell-crank lever having one end of a helical spring 2 connected to it,
the other end of which is attached to a hook secured to the bed a."
The presser according to our invention acts in the same manner as the ordinary
presser but for the purpose of insulating, it is constructed as follows-One arm 3
fig. 22 of the bell-crank fever has a sleeve of vulcanite or other suitable insulating
material placed upon it, prevented from turning round on the round arm by a pin, and
upon this sleeve the boss to which the pressing surface is attached is placed,
being secured from turning thereon by a pin and by a screw acting against a vulcanite
or other insulating washer ».
To the boss part one end of an electric conducting wire is attached having
helical coils to permit the presser to oscillate and the other end of this conducting
wire is connected by a binding screw with the conducting wire t.
When the slip of paper cut from the web is being wound upon the spindle e it
insulates the spindle from the presser e, but if the paper al is not wound upon the
spindle the presser comes in contact with the metal of the spindle e¹ and this allows
the current to pass through the frame of the machine to the electro magnet to stop
the machine as hereinbefore explained.
It will be understood that the cam d¹ in the ordinary machine lifts the presser e
away from the coiling spindle e¹ except when it is to press and it begins to press
against the paper being wound upon the spindle e¹ just after the first coil of paper
comes round opposite the presser.
The strength of electric current need only be sufficient to actuate the electric
magnets to lift the latch lever, and the same dynamo or source of electricity will act
for several machines as the current when operating to stop the machine only acts for
an instant and then its full force can immediately operate to stop other machines in
rapid succession when required.
It will be readily understood the arrangement for carrying out our improvements
by means of electricity may be varied without departing from the main features of
our invention.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that
what we claim is,
1. The stopping by automatic means of paper tube making machines when the web

page_text: breaks or is absent and also when the slip cut from the web fails to be rolled or wound
upon the spindle substantially as hereinbefore described.
2. The combinations and arrangements of mechanism for stopping by automatic
means paper tube making machines, when the web breaks or is absent and also when
the slip cut from the web fails to be rolled or wound upon the spindle substantially as
herein before described and illustrated by figs. 1 to inclusive also as hereinbefore
described and illustrated by figs. 6 to 8 inclusive, also as modified as hereinbefore
described and illustrated by fig. 9 and by figs. 10, 11 and 12 inclusive, also as herein-
before described and illustrated by figs. 13 to 1.7 inclusive and also as herein before
described and illustrated by figs. 18 to 24 inclusive of the drawings.
