Improvements in Cop Tubes and in Machinery or Apparatus for
making the same.
We, JOSEPH BRIGGS SWAILES, GEORGE SWAILES and JOIN 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 improved cop tubes are conical on their exterior, and may be either conical
or parallel in their interior, and the cone on the exterior is obtained by winding
more layers or coils of paper at what becomes the large, than at the small end of
the cop tube these layers or coils diminishing from the large to the small end of
the tube.
Cop tubes constructed in this manner are old and well known, the slips of paper
out of which such cop tubes are made being cut with one edge straight, forming a
base line for the large end of the tube, and two sides at an oblique angle to the
straight side, the wide end of the slip (which is first wound upon the spindle) at a
much less acute angle to the straight edge than the other side, which is oblique to
the straight edge, the result being that the angular corner of the paper slip has to
be passed across a slit in the winding spindle, and thus extends across the bore of
the cop tube, when rolled, and forms an obstruction to the cop tube passing freely
on to the mule spindle. By our invention the slips of paper forming each cop tube
have a straight edge forming the, base and large end of the cop tube, and an edge
oblique to the straight edge from one end, the edge at the wide end of the slip
being square or perpendicular to the straight or base edge, this square edge
extending the entire length of the cop tube, entering the groove in the coiling or
winding spindle but not crossing it, and therefore not obstructing the bore of the
tube which will thus pass on to the mule spindle more freely.
We have said above that the base edge of the slip for the cop tube is straight,
but in some cases it may be cut curved.
The mechanism or apparatus according to our invention for making our improved
cop tubes, two at a time without waste of material is combined and arranged to
operate as follows.
Paper in the web of the required width to make two cop tubes is unwound from
a reel and taken over suitable guiding rollers and over rollers by which paste or
other suitable cement is applied to its upper face, it then passes between finger
guides and between fluted rollers by which it is fed forward over a surface having
a cutting edge.
The lengthway of the web of paper fed, is parallel to the axes of two coiling
spindles, which are about the width of the web apart, which coiling spindles
together with connected mechanism are of ordinary arrangement and construction,
and they are actuated to wind up the paper slips and to move endways in a manner
similar to the winding or coiling mechanism of ordinary cop tube machines.
When a length of paper equal to the length of the finished cop tubes has been
fed over the above named surface having a cutting edge (straight or curved as
required) a nipping and holding arrangement actuated by cams takes hold of each
end of the piece of paper which is at the same time cut off from the web by a
moving shearing blade, (corresponding to the cutting edge) actuated by a cam.
Then the nipping arrangement carries the piece of paper cut off from the web
downwards until it rests upon another surface having a cutting edge passing in an
oblique direction under and across the slip cut from the web, and another moving
shearing blade actuated by a cam cuts the piece severed from the web diagonally,

page_text: so that each piece thus formed is of the same size and shape, one piece reverse to
the other.
The wide end of each diagonally cut piece is held by its nipper in such position,
that the square edge at the wide end of the slip is opposite, and in a line with the
groove in the winding or coiling spindle, the point end of one spindle being in one
direction and that of the other in the other direction and the spindles are slided
forward, to pass the groove in each of them over the ends of the slips while held by.
the nippers, then the spindles begin to rotate to wind or roll up each slip, and at
this moment the nippers release their hold and lift into the position ready to take
hold of the next piece to be cut from the web.
As before said each piece cut from the web is cut in two to form two cop tubes,
one piece to be wound or rolled upon one spindle on one side of the web, and the
other by the other spindle on the other side of the web.
When the slips are wound or rolled, the spindles move endways to strip the tubes
from their ends in the ordinary manner, and then wait for the next slips, and so on.
According to another modification of our invention, the axes of the coiling
spindles may be placed at a short distance from the edge of the web which is fed on
a horizontal line with the axes of the coiling spindles, and the slip cut from the
web while each end is held by nippers, is or may be moved forward a little over a
diagonally placed cutting edge and is then cut by a moving shearing blade, actuated
by a cam, then each pair of nippers carries the end of its slip sideways to come
opposite the groove in each of the coiling spindles.
According to our present experience we prefer one or the other of the modes
of operating above described, but do not confine ourselves thereto, as the mode of
cutting the pieces and the point at which they are to be cut from the web, and of
cutting the severed pieces into two, diagonally, and of carrying and presenting
them to the coiling spindles may be varied without departing from our invention.
In some cases oscillating fingers may be employed for feeding or assisting in
feeding the web to the cutters.
If desired arrangements may be combined with the mechanism above described
acting upon the principle of that described in the Specification of Letters Patent
granted to us No. 11,614 of 1887 for stopping the machine when the web breaks or.
a slip of paper fails to be coiled upon the rolling up spindles.
Dated this Third day of December 1890.

COMPLETE SPECIFICATION.
Improvements in Cop Tubes and in Machinery or Apparatus for
making the same.
We, JOSEPH BRIGGS SWAILES, GEORGE SWAILES 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 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 improved cop tubes are conical on their exterior and may be either conical
or parallel in their interior, and the cone on the exterior is obtained by winding
more layers or coils of paper at what becomes the large than at the small end of
the cop tube these layers or coils diminishing from the large to the small end of
the tube.
Cop tubes constructed in this manner are old and well known the slips of paper
out of which such cop tubes are made being cut with one edge straight, forming a
base line for the large end of the tube, and two sides at an oblique angle to the
straight side, the wide end of the slip (which is first wound upon the spindle) at a
much less acute angle to the straight edge, than the other side, which is oblique to

page_text: the straight edge, the result being that the angular corner of the paper slip has to
be passed across a slit in the winding spindle, and thus extends across the bore of
the cop tube, when rolled, and forms an obstruction to the cop tube passing freely
on to the mule spindle. By our invention the slips of paper forming each cop tube
have a straight edge forming the base and large end of the cop tube, and an edge
oblique to the straight edge from one end, the edge at the wide end of the slip being
square or perpendicular (or thereabouts) to the straight or base edge, this square
edge extending the entire length of the cop tube, entering the groove in the coiling
or winding spindle, but not crossing it, and therefore not obstructing the bore of
the tube which will thus pass on to the mule spindle more freely.
We have said above that the base edge of the slip for the cop tube is straight,
but in some cases it may be cut curved.
The mechanism or apparatus according to our invention for making our improved
cop tubes, two at a time without waste of material is combined and arranged to
operate as follows.
Paper in the web of the required width to make two cop tubes is unwound from
a reel and taken over suitable guiding rods and rollers, and over rollers by which
paste or other suitable cement is applied to its upper face, it then passes between
finger guides and between grooved rollers by which it is fed forward over a surface
having a cutting edge.
The lengthway and margins of the web of paper fed is parallel to the axes of
two coiling spindles which are about the width of the web apart, which coiling
spindles together with connected mechanism are of ordinary arrangement and
construction and they are actuated to wind up the paper slips and to move endways
in a manner similar to the winding or coiling mechanism of ordinary cop tube
machines.
When a length of paper equal to the length of the finished cop tubes has been
fed over the above named surface having a cutting edge (straight or curved as
required) a nipping and holding arrangement actuated by cams takes hold of each
end of the piece of paper which is at the same time cut off from the web by a
moving shearing blade (corresponding to the cutting edge) actuated by a cam.
Then the nipping arrangement carries the piece of paper cut off from the web
downwards until it rests upon another surface having a cutting edge passing in an
oblique direction under and across the slip cut from the web, and another moving
shearing blade actuated by a cam, cuts the piece severed from the web diagonally
so that each piece thus formed is of the same size and shape, but one piece is
reverse to the other.
The wide end of each diagonally cut piece is held by its nipper in such position,
that the square edge at the wide end of the slip is opposite and in a line with the
axis of, and groove in the winding or coiling spindle, the point end of one spindle
being in one direction, and that of the other in the other direction, and the spindles
are slided forward, to pass the groove in each of them over the ends of the slips
while held by the nippers, then the spindles begin to rotate to wind or roll up each
slip, and at this moment, the nippers release their hold and lift into the position
ready to take hold of the next piece to be cut from the web.
As before said each piece cut from the web is cut in two to form two cop tubes,
one piece to be wound or rolled upon one spindle on one side of the web, and the
other by the other spindle on the other side of the web.
When the slips are wound or rolled the spindles move end ways to strip the tubes
from their ends in the ordinary manner, and then wait for the next slips, and so on.
According to another modification of our invention, the axes of the coiling
spindles may be placed parallel but at a short distance from the edge or margin of
the web which is fed on a horizontal line with the axes of the coiling spindles, and
the slip cut from the web while each end is held by nippers is or may be moved
forward a little over a diagonally placed cutting edge or between a pair of shears,
and is then cut by a moving shearing blade or blades actuated by a cam or cams,

page_text: then each pair of nippers carries the end of its slip sideways to come opposite the
groove in each of the coiling spindles.
According to our present experience we prefer one or the other of the modes
of operating above described, but do not confine ourselves thereto, as the mode of
cutting the pieces and the point at which they are to be cut from the web, and of
cutting the severed pieces into two diagonally, and of carrying and presenting them
to the coiling spindles may be varied without departing from our invention.
In some cases oscillating fingers may be employed for feeding or assisting in
feeding the web to the cutters.
If desired arrangements may be combined with the mechanism above described
acting upon the principle of that described in the Specification of Letters Patent
granted to us No. 11,614 of 1887 for stopping the machine when the web breaks
or a slip of paper fails to be coiled upon the rolling up spindles.
Fig. 1 is a view of an ordinary form of a slip of paper from which cop tubes are
made with one corner passed through the longitudinal slit across the coiling spindle
partly represented in Fig. 1; Fig. 2 being an end view of the cop tube, showing
the corner of the slip of paper across it.
When the cop tube is formed from such a slip of paper the corner across the
slit of the winding spindle a, remains in the finished tube, and forms an obstruction
to the free passage of the cop tube on to the mule spindle as shown in Fig. 2.
The shape of a slip of paper when flat, used for our improved cop tubes, is
shown in Fig. 3 and it is forced with one edge perpendicular, or nearly so, to that
edge forming the long side of the slip, and which is at the large end of the tube,
and this end of the slip enters the longitudinal slit across the coiling spindle a, as
shown in Fig. 3 that edge of the slip being in a line with the longitudinal axis of
the coiling spindle, partly shown in Fig. 3, Fig. 4 being an end view of the finished
cop tube. The slips of paper for our improved cop tubes are cut from a web of
paper without waste, this web being the width required to form the slips for two
cop tubes.
Fig. 5 shows a slip of paper as cut from the web; which in full line represents
the slip for two cop tubes when severed from the web, perpendicular to its two
edges, with a full diagonal line across it, showing where the slip is divided into two
slips to form two cop tubes, one slip reversed to the other.
In dotted line in Fig. 5 the slip is shown as severed from the web, slightly at an
angle to its two sides as it is sometimes cut to provide when being coiled, for the
slight taper of the spindle and the dotted diagonal line shows how the severed slip
is divided to form slips for two cop tubes each of which when wound are in the
form represented by Fig. 6 an outside elevation.
Fig. 7 is a flat view of a slip of paper as severed from the web when cut with
curved shears and then divided to form slips for two cop tubes by a straight
diagonal line as shown.
Figs. 8, 9 and 10 are views illustrating our improved machine according to one
modification of our invention, for making cop tubes. In these figures only parts of
the complete mechanism are shown, some parts of ordinary and well known
mechanism are also shown, but other parts are omitted.
'
Fig. 8 is a side elevation, Fig. 9 is a cross section at A-B Fig. 8 looking to
that end at which the web of paper is fed, and Fig. 10 is a plan view.
The mechanism is carried upon a bed plate or frame b, which is supported on
suitable legs.
, is the web of paper on a roll a', (Fig. 8) in suitable bearings the web from
the roll, passes on one side of a guiding rod c, and then on the other side of
another guiding rod c', carried in suitable brackets.
The web then passes to the underside of the lower roller of a pair of drawing
and feeding rollers d, and these rollers have their bearings arranged, and are
driven in an ordinary manner (shown best in Fig. 10) the upper roller being
grooved as shown in Figs. 9 and 10.

page_text: ༦༡
presses against the periphery of a drum or roller e, rotated in suitable bearings-
this drum e, revolves in a trough e containing suitable paste which is imparted to
the surface of the web of paper.
There is a stationary brush e, or scraper or "doctor" carried on a suitable
bracket which comes against the pasted surface of the web, and this brush e²,
removes the superfluous paste which falls upon the paste supplying drum e, or into
the trough e'.
These pasting arrangements are similar to those used in ordinary cop tube making
machines.
The rollers d, feed at a uniform speed a length of web for each operation of the
machine used in simultaneously making two cop tubes, but these rollers d, may be
driven intermittently, if desired to supply the length of web necessary and at the
time required. From the feeding rollers d, the web passes over a supporting rod c²,
carried upon a bracket and then passes between guiding fingers or wires f, which
act above and below the web .c.
These guiding fingers are secured at one end in rods f³, passing across the web x,
the rods being carried upon brackets.
The fingers, extend in the lengthway of the web ar, and pass freely through
spaces formed in the grooved feeding rollers d', which have their axes in suitable
bearings and are driven intermittently to feed the required length of web at the
time required by intermittent gearing of ordinary arrangement, best shown by
Fig. 10. Under the web there is a bracket or stand g', secured to the bed plate b,
seen clearest in Fig. 9, to which stand a shearing edge is secured.
The moving shearing blade g, is secured to a pivot or fulcrum 92, at one end, and
to the other end an arm g³, is secured, that extends over a cam g', and this arm g³,
has one end of a helical spring g', secured to it, the other end of which is attached
to a bracket y, secured to the bed plate b, (see Fig. 9).
Before proceeding further with the description of the mechanism operating upon
the paper, we will describe the driving mechanism. h, are the fast and loose pulleys
for the driving belt, on the end of a cross shaft ', in suitable bearings, and the
other end of this cross shaft ', has a fly or hand wheel 2, secured upon it
(see Fig. 10).
There is a bevel wheel on the cross shaft h', at each side of the machine, and
each bevel drives a corresponding bevel wheel on two longitudinal shafts i, and j,
one on each side of the machine.
The shaft, on one side (see Figs. 9 and 10) drives the intermittent feeding
rollers d', and the coiling spindle a, on that side, which is rotated, and is then
stopped for a time once for each cop tube. These coiling spindles a; can rotate and
their shafts a', can slide endways in their bearings, and they are 'rotated by a spur
wheel gearing with a long spur pinion a², and are rotated at the times required by
such gearing as is used for this purpose in ordinary cop tube making machines.
The coiling spindle a, receives end reciprocating movement from a suitable cam a³,
on the cross shaft, that acts upon a bowl in a lever a', having its fulcrum a³, on
á bracket attached to the bed plate b.
The bowl on the lever a, comes against the end of the shaft a', and moves it in
one direction, and a spiral spring a, on a bracket secured to the bed having a
forked end acts upon a collar on the coiling spindle shaft a', and moves it in the
other direction.
.
The other coiling spindle on the right of Fig. 9, is also operated by a cam a³, on
the cross shaft h', which acts upon a bowl in a lever a', on the opposite side of the
shaft, connected by a rod a', with another lever a³, having its fulcrum a³, and a
bowl on the lever a, acts upon the end of the other shaft a', to move it in one
direction, the reverse movement being produced by a spiral spring aª.
These coiling spindles a, in all other respects not shown or described are arranged
and actuated same as in ordinary cop tube making machines.
When the coiling spindles a, stop rotation, the longitudinal slits across them, are

page_text: in a line with the end of the slip of paper which is to be wound upon them, and
while the slip of paper is being wound upon each spindle there is a surface acting
against the paper and pressing it upon the spindle which surface is upon one arm k,
of a bell crank lever having its fulcrum k¹, on a bracket, on the bed plate, (only
one of these pressing levers k, for one spindle is shown in Fig. 9).
The lever k, is made to press with the required force by a spiral spring k², one
end of which acts against one arm k³, of the bell crank lever. The fulcrum of the
spring 2, is upon a bracket secured to the bed plate b.
Part only of the arm 3, of the bell crank lever that is acted upon by the spring k²,
is shown in full line in Fig. 9, the remainder of it being represented in dotted line
as passing under the surface of the cam k, on the shaft, actuating the bell crank
lever, this cam k, allows the pressing surface to operate at the time required, and
then causes it to lift clear of the spindle a, and the cop tube coiled upon it.
These presser arrangements (there is one for each coiling spindle) are similar to
those used in ordinary cop tube making machines.
When the slips are coiled upon the spindles a, each is pushed from the spindle
when it is drawn endways as the large end of the cop tube then comes against an
eye in a bracket a secured to the bed, such eye fits the coiling spindle a, and as
the tube is too large in diameter to pass through the eye it is stripped from the
spindle and falls into a suitable receptacle below. These arrangements for
stripping the cop tubes from the spindles are similar to those used in ordinary cop
tube making machines.
Sometimes the ends of the cop tubes adhere to the stripping eye and do not fall
and are then in the way and prevent the coiling of the next slip fed to be operated
upon, and to compel them to fall the bent ends of wire levers (one for each spindle)
are made to strike the adhering cop tubes downwards at the proper time.
These wire levers l, are secured to the end of a shaft l, in suitable bearings on
brackets or stands secured to the bed plate b, (see Figs. 8 and 10) and to this
shaft, one end of a short length of leather or other flexible material is secured
the other end of which is connected with one end of a helical spring 12, the other
end of which is attached to the bed plate b, (see Fig. 10).
This spring, acts to partly rotate the shaft l, aud lift up the wire levers l, to
the position in which they are shown in Fig. 8, there being a stop to limit the
oscillation of the shaft l', in that direction. The outer end of the shaft l', has
an arm 3, near the shaft j, upon a projection from which arm a cam 4, upon the
shaft j, can act and cause the shaft l', to oscillate and the ends of the wire levers l,
to make the descent to knock down the cop tubes from the stripping eye, when
they adhere to it, the spring 1, causing the levers l, to lift again after each descent.
Just before or at the time the slip of paper to form two cop tubes is being
severed from the web r, there are two pairs of nipping fingers m, that act to take
hold at each end-and as both pairs are alike and act and are operated in like
manner, we will only describe one pair of fingers on one side and for one end of
the slip of paper to be coiled.
There is a bracket secured to the bed plate b, which has a stud m', secured in
it horizontally, which stud is the fulcrum of two levers m, forming one pair, each
lever passing over its cam m², on the shaft i, for one pair of levers and the cam m²,
on the shaft j, for the other pair of pinching levers m.
The lever m,
to act upon the underside of the slip is bent as shown best in Fig. 9,
to be clear of the other mechanism and it has a projection that comes against the
upper surface of the bed plate d, when in its lowest position, in which it should be
steady in order that the edge of the slip of paper to be coiled may be correctly
presented to the slit in the coiling spindle.
After the slip has been taken by the coiling spindle the upper nipping lever m,
is lifted to the level at which the slip of paper is severed from the web x, and
the other follows shortly after the cam which acts upon the upper lever m, causing
it to lift, clear of the upper side of the slip to be severed from the web.
Both levers m, are acted upon by one end of a helical spring m³, the other end

page_text: of which is secured to the bed plate b, the spring m³, being attached to the upper
lever so that when the cam for the upper lever causes it to be lowered, the
spring m³, pulls it down against the paper and presses upon the pinching surface
of the lower nipper, so that the slip of paper is thus pinched and held down
between the two, both nipping levers m, being then pulled down by the spring m³,
as the cam for the lower lever permits until the projection m*, on the lower lever
rests upon the upper surface of the bed plate b.
The slip is released by the nippers when the cam for the upper lever m, lifts it
in advance of the lower lever, the cam for which acts later.
It will thus be seen that when the slip is severed from the web x, the two pairs
of nippers n, one on each side have hold of each end of it and they simultaneously
lower it to the level of a lower stationary shearing edge n, secured to the bed
plate 6, in the required diagonal position. The upper movable shearing blade n',
having its fulcrum at no, (Fig. 10) in its normal position is above the upper level
of the slip when severed from the web and descends as the slip is carried down by
the two pairs of pinchers m, and when in its lowest position the slip is divided into
two, diagonally, (see Fig. 5).
The diagonally shearing blade n', is lifted by a helical spring n³, one end of
which is secured at one end to an arm n³, from it, the other end of the spring n²,
being attached to a stand no, secured to the bed plate b.
The shearing blade n', is moved to cut by a cam n³, on the shaft j, see Figs. 8
and 10.
Another modification of machine for carrying out our invention is illustrated by
Figs. 11 to 15 inclusive.
In this modification, the web a, is fed, pasted, and the slips are severed from it,
as hereinbefore described in reference to the modification illustrated by Figs. 8, 9
and 10, but the slip severed from the web is not lowered to the level of the coiling
spindles as in Figs. 8, 9 and 10, the axes of which are in that modification in a line
with, but below the margin of the web at each side, but in this second modification
the slips when severed from the web are carried forward on the same level as the
web, to a position to give space to divide it into two, by the diagonal shears.
Fig. 11 is a diagram in which , represents a portion of the web the arrow upon
that figure points in the direction in which it is being fed.
g, is a part of the lower stationary shearing edge; g, part of the upper shearing
blade, and 2, the two severed slips moved forward over the fixed lower diagonal
shearing edge n, and n', a part of the upper diagonal shearing blade, the two
portions of the divided slip a², being shown, the latter in their positions after having
been severed diagonally, and moved away from each other into the position in which
their ends are to be presented to the coiling spindles.
Fig. 12 is a longitudinal elevation partly in section,
Fig. 13 is a transverse elevation partly in section on the line A-B Fig. 12, and
looking from the end at which the web a, is fed,
Fig. 14 is a transverse elevation in section at C-D Fig. 12, looking towards the..
rollers d', for feeding the web, and
Fig. 15 is a plan view.
The moving blade 9, of the shears for severing the slip from the web a, is carried
on a stud 2, in a bracket and it has an arm g³, acted upon by a cam g, on the
shaft j, and its return movement is effected by a spring g, Figs. 14 and 15.
The coiling spindles indicated by a, are arranged in like manner to those
described in reference to the first modification.
The blades of the shears for dividing the severed slip diagonally into two are
both jointed on the same stud n³, mounted on a bracket.
The levers of the blades are at a right angle with the shaft j, and then bend to
the angle required, to give the diagonal cut.
There is one bracket n', secured to the bed, which bracket has two arms to each
of which one end of a helical spring n³, and n³, is attached, the other ends of these

page_text: springs being respectively attached to an arm na, from one shearing blade n', and
the other to an arm nb, from the other blade n.
22
One arm n³, is a double arm, one arm of which rests against the side of a cam n*,
on the shaft, the arm nb, from the other blade n, rests upon the upper surface of
its cam ne, on the shaft j, (see Figs. 14 and 15) thus arranged both shears for the
diagonal cut will open and close at the required time.
Under the bed plate b, two slideways formed by two bars b', are secured to
projections from the bed plate, and upon these slide bars b', a carriage p, is arranged
to slide to and fro in the lengthway of the slideways b', (see Fig. 12).
To the slide p, one end of a rod 1, is jointed, the other end being connected to a
lever p², having its fulcrum³, on a bracket secured to the bed plate b. This lever
is acted upon by a cam p, on the cross shaft h', one way, and is pulled back by an
helical spring p, attached to the slide p, at one end and to a bracket ³, under the
bed b, at the other end
If desired the slide p, may be moved both ways by a double acting box cam
acting upon a bowl in the lever p².
Upon the slide p, two arms q, are jointed at q', one at each side of the arm, and
there is a bracket 92, secured to each jointed arm g, the end of which bracket comes
under a broad cam g³, on the shaft j, on one side, and on the shaft i, on the other
side.
The part acted upon by each cam is jointed to the bracket 92, at y³, and there
is a screw 9, in the bracket 92, so that the hinged part 9', may be adjusted so that
the cam surface 73, will come upon it sooner or later as required, for adjustment.
The two upright arms q, jointed to the slide p, are drawn towards each other by a
helical spring, one end of which is connected to each arm q.
To each of the arms y, there is another bracket q, secured to carry an adjusting
screw 9, the end of which will come against an upright stand q", secured to the
slide, so that when the cams ³, permit, the ends of the set screws 1, will form stops
for one position of the upright levers q.
Each of the upright levers q, forms the lower nipping surface 9", (stationary so
far as rise and fall) coming under the slip, and to each of them an upper lever qº, is
jointed at q. forming the upper nipping surface.
The arms of these nippers are bent in the form shown in Fig 12 for one side
(the right of Fig. 14) in order that the shears for the diagonal cut may pass between
and work clear of them..
The arms of the nippers for the other side need not be bent or if so, not to the
same extent, as they are clear of the end of the diagonal shears.
The nipping lever, jointed to the lever q, has an arm 7, from it see Fig. 12,
which is acted upon by the end of a spiral spring, the fulcrum of which is secured
to the side of the lever q, to which is also secured the fulcrum 9%, of a bell crank
lever q, the horizontal arm of which forms a hook to catch upon a projection on
the arm qe, of the jointed pinching lever qº, and the hook arm of the bell crank
lever q, is pulled down by a helical spring q', one end of which is attached to it and
the other end to a bracket q', secured to the lever q.
There is a bracket 9, also secured on the lever q, the side of which acts as a stop
to limit the movement of the jointed pinching lever 9°.
There is a bracket r, on the bed plate b, to carry an adjusting screw, the point
of which will come opposite and against the vertical arm of the bell crank lever g",
when the slide p, has moved towards the end of the set screw stop, and this will
cause the hook arm of the bell crank lever qh, to lift and release it from the
projection from the arm qe, of the jointed pinching lever q, and allow the spiral
spring q, to press the pinching surface of the lever g, upon the upper side of the
slip and also the latter against the lower stationary pinching surface q, this will
grip both ends of the slip severed from the web x, (as the mechanism upon both
levers is the same) and when the slide p, moves away from the web, the nippers
carry the slip with them to the position to be divided by the diagonal shears, then

page_text: the cams g, act simultaneously to move the arms y, to the position in which each
pair of nippers presents the ends of the slip held by them to the coiling spindles a,
as shown in Fig. 14, then the nippers are made to release their hold upon the slips
by the arm 9, of the jointed pinching lever q, on each side coming near to the end
of a rods, (one for each pair of nippers) sliding in a guide formed by a bracket s',
secured to the bed b, this rod s, being acted upon by a cam s², which comes against
a cross head s³, on the end of the rod s, and slides it so as to lift and open the
nippers, in which open position the hook arm of the bell crank lever qb, catches
upon the projection on the arm qe, and holds the nippers open.
There is a sliding rod s, and cam 2, for each pair of nippers and there is a helical
springs, on each rcd s, to keep its end against the cam for it, see Fig. 15. Other
arrangements may be used in place of that described for actuating the nippers.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed we declare that what we
claim is.
1. Cop tubes made from slips of material severed without waste from a web of
material wide enough to make two cop tubes the slip to form each cop tube being
cut to the shape hereinbefore described and illustrated by Figs. 3, 5 and 7 of the
drawings and coiled into the cop tube form shown by Fig. 6 by having that edge
of the slip of material entered into the slit in the coiling spindle parallel with the
longitudinal axis thereof as herein before described and illustrated by Fig. 3 of the
drawings.
2. The making of cop tubes by machinery in which a web of material wide enough
to form two cop tubes is fed with its edges or margins parallel to the longitudinal
axes of the coiling spindles, and in which a slip is severed from the web, and is then
carried by mechanism to shears or cutters to be divided diagonally, after which
such divided slips are presented to the coiling spindles each to be formed into cop
tubes, substantially as hereinbefore described and illustrated by the drawings.
3. The combination and arrangement of mechanism substantially as and for the
purpose hereinbefore described and illustrated by Figs. 3, 5, 8, 9 and 10, and by
Figs. 3, 5, 11, 12, 13, 14 and 15 of the drawings.
Dated this Fifteenth day of August 1891.
