PROVISIONAL SPECIFICATION.
Machine for Manufacturing Tubing and the Tube formed thereby as
a New Article of Manufacture.
I, CLAUDE KENNEDY MILLS of 23 Southampton Buildings in the County of
Middlesex, Patent Agent do hereby declare the nature of this invention, a
communication to me from abroad by Daniel Nolton Hurlbut, of the City, County
and State of New York, in the United States of America, Manufacturer, to be
as follows:
This invention relates to the machine for forming tubing having a core formed
from a flat tape bent longitudinally into tubular shape and having a seam formed
either by abutting or overlapping edges; around this core tape is spirally wound,
another tape or tapes the whole being secured together by a suitable adhesive
substance. Preferably where more than one tape is used they are arranged so
as to break joints one to the other. The tube just described constitutes a new
article of manufacture and is preferably made by the novel machine herein
described.
My machine is more especially adapted to be used for the manufacture of
paper tubing having a longitudinal core and spiral wrappings suitably cemented
together as above stated, and it is constructed as follows:
A sectional mandrel around which the core of the tube is formed is adapted
to be fed through the machine and at the same time rotated. In its movement
in a right line through the machine it carries with it the tape which forms the
core, the tape being reeled off a supply reel which has a motion of rotation to
correspond with the rotation of the mandrel so that a fixed relative position will
be maintained between the mandrel and reel.
The tape forming the core, when the machine is started, is bent around the
mandrel so that when the mandrel commences to travel through the machine it will
carry with it through a cone shaped forming die the said tape. This forming die
folds the tape around the mandrel. After the tape and mandrel have passed
through the forming die one or more tapes are led at an angle to the path of
travel of the mandrel so that by the rotation of the mandrel they will be spirally
wound on the core tape carried by the mandrel. These tapes are carried from
suitable supply reels through paste boxes within which are arranged suitable
apparatus for applying paste on the surface of the same which will come next
the core or other inner tape. The tube is now completely formed but preferably
apparatus operated by the mandrel is arranged to automatically cut the tube
into determined lengths. This is done preferably by arranging a sleeve through
which the mandrel and the tube formed thereon travel. At its end this sleeve
is provided with a detachable cap to close the same; against the end of which
cap the travelling mandrel strikes and pushes the same and the sleeve with it,
the sleeve for this purpose having a sliding connection with its bearings or sup-
ports until the catches which hold the detachable cap in place strike a releasing
piece whereby the catches are released and the cap drops off, a weight arranged
at the other end of the sliding sleeve draws it backward to its original position.
This sliding movement of the sleeve operates a knife blade so arranged as to be
carried longitudinally by the sliding sleeve under an inclined ledge on a
stationary part of the machine which depresses the knife blade into contact with
the material of the tubes and cuts the same. By this arrangement it will be
evident that the tubes are cut in definite lengths, preferably the sections of man-
drel are screw-threaded together and are of such length that the cut of the tube
is made near one of the joints of the mandrel so that as the mandrel and tube
are together fed out of the machine, the operator can detach the section of the

page_text: mandrel and tube from the main length of mandrel the length of tube being
removed from its section of mandrel which section is carried to the other end of
the machine and used over again.
For giving to the mandrel a motion of rotation as well as a motion in a
right line, the feed rollers are arranged so that they will have a motion of rota-
tion on their own axis, and also a motion of rotation with the mandrel as the
axis, and there are preferably arranged a set of feed rollers near the exit end
of the core forming die and a set of feed rollers beyond the point where the
spiral tapes are wound on the core.
A pusher is employed at one end of the mandrel operated by a weight; the
pusher having a socket into which an end of the mandrel fits, and it slides in
grooves, a weight tending to pull it in the direction of the mouth of the core-
forming die.
Preferably also a suitable pressing device is arranged, at the exit end of, the
core-forming die so that the said core will be pressed to the mandrel and held
firmly from slipping thereon during its rotation. Also there are arranged suit-
able pressing devices for the spirally applied tapes.
A paper tube having a core such as herein described with a tape or tapes
spirally applied thereon has the advantage of cheapness while affording consider-
able strength to resist ordinary crushing strains so that the same is adapted to
be conveniently and safely used in considerable lengths.
Paper tubes of this construction are adapted for use as conduits for electrical
conductors and for the manufacture of speaking tubes &c.

Machine for Manufacturing Tubing and the Tube formed thereby as
a New Article of Manufacture.
a
I CLAUDE KENNEDY MILLS of 23 Southampton Buildings in the County of
Middlesex Patent Agent do hereby declare the nature of this invention
communication to me from abroad by Daniel Nolton Hurlbut of the City County
and State of New York in the United States of America Manufacturer and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to a machine for forming tubing having a core formed
from a flat tape bent longitudinally into tubular shape and having a seam formed
either by abutting or overlapping edges; around this core tape spirally wound
another tape or tapes the whole being secured together by a suitable adhesive
substance. Preferably where more than one tape is used they are arranged so
as to break joints one with the other. The tube just described constitutes a new
article of manufacture and is preferably made by the novel machine herein-
after described.
The machine is more especially adapted to be used for the manufacture of
paper tubing having a longitudinal core and spiral wrappings suitably cemented
together as above stated, and it is constructed as follows:
A sectional mandrel around which the core of the tube is formed is adapted
to be fed through the machine and at the same time rotated. In its movement
in a right line through the machine it carries with it the tape which forms the
core, the tape being reeled off a supply reel which has a motion of rotation to
correspond with the rotation of the mandrel so that a fixed relative position will
be maintained between the axis of the mandrel and reel,

page_text: The tape forming the core, when the machine is started is bent around the
mandrel so that when the mandrel commences to travel through the machine it
will carry the tape with it through a cone shaped forming die. This forming die
folds the tape around the mandrel. After the tape and mandrel have passed through
the forming die one or more tapes are led at an angle to the path of travel of the
mandrel so that by the rotation of the mandrel they will be spirally wound on the
core tape carried by the mandrel.
These tapes are carried from suitable supply reels through paste boxes within
each of which is arranged suitable apparatus for applying paste on the surface of
the tapes which will come next the core or other inner tape. The tube is thus
completely formed but preferably apparatus is arranged operated by the mandrel
to automatically cut the tube into determined lengths. This is done preferably
by arranging a sleeve through which the mandrel and the tube formed thereon
travels.
At its end this sleeve is provided with a detachable cap to close the same.
Against the end of this cap the travelling mandrel strikes and pushes the same and
the sleeve with it, the sleeve for this purpose having a sliding connection with its
bearings or supports, until the catches which hold the detachable cap in place
strike a releasing piece whereby the catches are released and the cap drops off, a
weight arranged at the other end of the sliding sleeve drawing it backward to its
original position. This sliding movement of the sleeve operates a knife-blade so
arranged as to be carried longitudinally by the sliding sleeve, under an inclined
ledge on a stationary part of the machine, which ledge or lip depresses the knife-
blade into contact with the material of the tubes and cuts the same. By this
arrangement it will be evident that the tubes are cut in definite lengths. Prefer-
ably the sections of mandrel are screw-threaded together and are of such length
that the cut of the tube is made near one of the joints of the mandrel so that
as the mandrel and tube are together fed out of the machine, the operator can
detach the sections of the mandrel and tube from the main length of mandrel
after which the length of tube is removed from its section of mandrel, which
latter is carried to the other end of the machine and used over again.
For giving to the mandrel a motion of rotation as well as a motion in a right
line, the feed rollers are arranged so that they will have a motion of rotation on
their own axis and also a motion of rotation with the mandrel as the axis and a
set of feed rollers is preferably arranged near the exit end of the core forming die
and a set of feed rollers beyond the point where the spiral tapes are wound on the
core.
A pusher is employed at one end of the mandrel operated by a weight, the
pusher having a socket, into which an end of the mandrel fits, and sliding in
grooves, a weight tending to pull it in the direction of the mouth of the core
forming die.
Preferably also a suitable pressing device is arranged at the exit end of the
core-forming die so that the said core will be pressed to the mandrel and held
firmly from slipping thereon during its rotation. There are also arranged suitable
pressing devices for the spirally applied tapes.
A paper tube having a core such as herein described with a tape or tapes spirally
applied thereon has the advantage of cheapness while affording considerable
strength to resist ordinary crushing strains and thereby the same is adapted to be
conveniently and safely used in considerable lengths. Paper tubes of this con-
struction are adapted for use as conduits for electrical conductors and for the
manufacture of speaking-tubes &c.

1 in the drawings is the bed plate of the machine which is suitably supported on
the standards 2. 3 is the mandrel around which the tube is formed. This mandrel
is preferably made in several lengths threaded or socketted together so that in
length it shall be equal to about the length of the machine, and should be of
sufficient strength to withstand the crushing action of the feeding devices.
Preferably the several sections of the mandrel are of the same length as the
length of the tubes desired; when so formed the cutting device hereinafter
described is operated to cut near the junction between the sections, so that the
section of mandrel and length of tube may be taken from the machine together.
I will first describe the feeding mechanism assuming, for facility of description,
that the mandrel alone is to be fed through the machine without being rotated.
4 is a long table, grooved as shown in Fig. 1. In this groove slides the pushing
piece 5, upon the upright arm of which is mounted the recessed rotating piece 6,
into which one end of the mandrel is placed. To the horizontal arm of the pushing
piece 5 is attached a cord 7, which runs in the groove of the table towards and
over the pulley 8, and has secured to it the weight 9. This weight is about equal
to the weight of the mandrel and serves to pull the mandrel into the machine until
it is in contact with the feed rollers.
10 is a section of the guide tube for the mandrel, the whole guide tube being
formed in several sections, serving to guide and support the mandrel in its passage
through the machine. This section 10 serves also to separate the material for the
tube and the mandrel, the mandrel being inside and the material outside, whereby
there will be no contact between mandrel and material until they are about to enter
the forming die.
11 is the forming die, shown in section, Fig. 3, having a cone-shaped mouth 12,
the cylindrical throat 13. 14, 15 are feed-rollers, having slightly fluted peripheries,
mounted in bearings in a rotating frame hereinafter more particularly described.
These rollers are preferably adjusted so as to be adaptable for different sizes of
work and one of them is preferably provided with a spring so as to cause it to
exert a yielding pressure on the mandrel.
16 are the adjusting screws for the rollers, and 17 is a coiled spring provided for
one of them and located as shown so that its tendency will be always to press the
roller onto the mandrel.

page_text: 18 is another section of the guide tube for the mandrel of uniform bore with the
throat 13 of the forming die provided at its exit end with a clutch formed in two
parts 19 and 20, each part being provided with longitudinal serrations 21, to
prevent slipping of the tube and tube material while rotating. The parts 19
and 20 have a dovetail connection with the end of the tube 18 as shown in
Figure 12; 22, 23 are flat springs secured at one end to the tube 18 and at the
other bearing one upon the part 19 and the other upon the part 20 and being
provided with set screws 24, 25, to adjust the degree of spring pressure. When
the two parts 19 and 20 are in contact as shown at Fig. 11, the circle described
by the tops of the serrations will be smaller than the bore of tube 18 whereby
adjustment for different sizes up to the diameter of bore of tube 18 is permitted.
26 is a hollow support for a portion of the guide tube for the mandrel, but of
much larger diameter than the mandrel. 27 is a removable section fitting into one
end of support 26 as shown different sizes being used for different sized mandrels.
28, 29, 30 and 31 are feed rollers similar in construction and operation to the
rollers 14 and 15 described above.
32 is another support similar to 26 and having a removable section 33 similar to
section 27 for the same purpose. 34 is another section of the guide tube for the
mandrel, fitting into and supported by the section 35. One end of this tube 34 is
split longitudinally as shown in Fig. 4, and sprung; 35 and 36 designate two of the
slits of which there are preferably four. Surrounding the split end of the tube is
the rubber ring 37, which by moving on the split end of the tube will expand or
compress the opening, thus permitting the degree of grip on the mandrel to be
regulated.
38 is another section of the guide tube for the mandrel, supported similarly to
the portion 34 by means of the support in bearings 39 and removable pices 40 at
one end and supports 41, 42 and 43 and sliding pieces 44, 45 interposed throughout
its length.
Besides the motion of translation which the mandrel has, it has also a motion of
rotation, for a purpose as will appear hereinafter. This motion of rotation is
effected by means of the feed-rollers above referred to and so that there will be no
retardation of the rotation of the mandrel by its guiding tube, the several sections
thereof except the first are also rotated at the same speed as the mandrel. I will
describe the construction for effecting the rotations above referred to and as the
main object of rotating the mandrel is to wrap the core of the tube in process of
manufacture with a tape or tapes, I will in this connection describe also the means
of supplying the core tape and winding tapes for the tube to the mandrel.
46 is the driving belt, belting as required onto one or the other of the
pulleys 47, 48, one of which is a fast and the other a loose pulley. On either end
of the pulley shaft is a gear 49, 50. The gear 49 engages with the gear 51, which
is mounted on a hub 52, formed on the rectangular rotating frame 53. On the
opposite end of this rectangular frame is formed another hub 54, surrounding which
is a pinion 55. The hubs of the rectangular frame are supported in bearings 56,
57, and the frame is rotated therein. through the gear 51, which is rigidly secured
to it. The pinion 55 is rigidly secured by a number of pins 58, 58, to the
bearings 56 and does not rotate.
Carried by the frame 53 is an arm 59 in which is mounted a shaft 60 which
carries at one end the pinion 61 and at the other end of the bevel 62. The
pinion 61 meshes with the stationary pinion 55 and has a motion of revolution
around it transmitted to it by the arm 59 of the rectangular frame. The engage-
ment of the teeth of the two pinions 55 and 61 rotates the pinion 61 thus driving
the shaft 60 and bevel gear 62. 63 is a bevel gear free to rotate on a stud 64" on
the arm 59 driven by the bevel gear 62. To the face of the bevel gear 63 is
secured one end of the jointed or tumbling shaft 64, the other end of which is
secured to the shaft of the upper feed roller 14, the lower feed roller 15, being
driven by means of the pinion 65 on the end of the shaft of the upper feed roller.
By means of this jointed or tumbling shaft arrangement the adjustment of tho

page_text: feed rollers to the requirements of different size tubes is permitted through the
adjusting screws 16.
The gear 50 engages with a gear GG fast on the hub of another rotating rect-
angular frame 67 in which is mounted the feed rollers 28, 29, 30 and 31 already
referred to. The arrangement for driving these feed rollers, so that they will
impart to the tube a motion of rotation as well as of translation is similar to that
described in connection with the frame 53, except that there being two pairs of
feed rollers to this frame there is an intermediate gear 68 to transmit motion from
one set of gears of the feed-roller shafts to the other. 69 is the stationary toothed
disc. 70 is the gear having the motion of revolution around 69. 71 and 72 are
the bevel gears for driving the jointed or tumbling shaft 73 and 74, 75, the bearings
for the rectangular frame.
On the hub of the frame 67, towards the exit end, is mounted a gear 76 which
drives a gear 77 on shaft 78, another gear 79 on the same shaft driving gear 80
secured to and driving the continuation of the guiding tube for the mandrel.
As will be seen the forming die and the sections 18 26 and 34 of the guiding
tubes for the mandrel, being secured in the rectangular rotating frames will be
rotated with said frame and therefore will not tend to set up friction to retard the
rotation of the mandrel. This also may be said of the section 38 of the guide tube
for the mandrel which is driven by the gear 80.
Formed in one piece with the rectangular frame 53 is the yoke piece 81 and on
the end of an arm 82 are projections which form bearings for the supply spool 83,
the weight of the spool and its contents being counterbalanced by the counter-
balance 84 at the end of an arm 85 projecting from the yoke piece 81. The rotation
of the yoke piece 81 will of course rotate the supply bobbin. 86. is a guide roller
for the tape mounted on a spindle 87 having bearings in the yoke-piece 81. 88 is
a guard, within which the yoke piece and connected parts rotate, for the purpose of
preventing injury to operatives.
Starting with one end of the mandrel in the forming die and the other end in
the rotating piece 6, the operator will bring the tape around the roller 86 and along
the mandrel threading the end of the tape and mandrel together into the mouth
of the forming die, the weight 9 forcing them both together between the first pair of
feed-rollers. The belt being then shifted to the fast pulley the machine will feed
the mandrel toward the exit end, at the same time draw a supply of tape from the
supply spool 83 which is also rotating with the mandrel. The passage of the tape
through the forming die, with the mandrel will cause the tape to take a tube forma-
tion with butt edges which will be rotated with the mandrel by the rotation of
the feed roller and which will be prevented from slipping on the mandrel by the
longitudinal serrations 21 in the gripping jaws 19, and 20 which are used at a point
where the greatest likelyhood of slip exists that is at the point near where the
outer wrapping is applied to the core already formed. As shown in Figs. 1 and 7
this wrapping consists of two tapes which are preferably of the same material as
the core.
These tapes are fed on the core at an angle as shown so as to be wound
spirally thereon, and are coated with paste on the surface to come in contact with
the core, in a manner hereinafter to be described, and are supplied from supply
spools 89 and 90, mounted in a box 91 pivotted on a vertical pin 92. The operator
having properly applied the coated side of the winding tapes to the core, the
rotation of the latter will wind them upon it while its forward motion and the
angle at which the tapes are fed will cause the winding tapes to be wound spirally
as shown. To secure the adherence of the winding tapes and core, at the points of
application of the former to the latter, the adjustable pressers 92 and 93 are used,
shown in detail in Figures 9 and 10. These pressers are held in a frame 94 by
the set screw 95 and are supplied with handles 96 and 97 for convenience. At the
rear end the pressers are in contact with the coiled springs 98, 99 which are held in
place by the plates 100 and 101. To regulate the tension of the coiled springs the
cams 102 and 103 on the ends of the regulating screws 104 and 105 are used. At
the front end the pressers are of the form of a half circle of the size of the tube

page_text: amp projection as shown. Tassing the point where the wrap-
ping is applied to the central core, the tube, which is now in its completed form
is fed by the feed-rollers through the several sections of the guide-tube, which
are of enlarged diameter to correspond with the increased diameter of the tube,
to the exit end of the machine, a cutting mechanism hereinafter described auto-
matically operating to cut the formed tube into determined lengths, the cut
being made preferably at the point where two sections of the mandrel meet so
that the operator will receive a section of mandrel and piece of tube of equal
length which he can separate, the section of mandrel being returned to the feed
end of the machine to be used again.
The pasting apparatus hereinbefore referred to is shown most clearly in Figs. 7
and 8. 106 is a spindle carried in arm 107 extending from a pin 108 projecting
from box 91. At its upper end this spindle passes through a longitudinal slot 109
of the bed plate and has a collar 110 surrounding it above the slot resting on the
bed plate and a nut 111 below the bed plate working on a threaded portion of the
spindle. Upon another collar 112 on the top of the spindle is a pivot 113 upon
which the plate 114 is mounted and swings. Upon this plate 114 are supported
the paste boxes 115 and 116, the latter being pivotted to it so as to be adjustable
thereon. As the box 91 is pivotted ou a vertical axis 92, and the spindle 100 is
supported by it, the spindle and parts supported by it may be swung in a longi-
tudinal direction to the extent of slot 109 and may be clamped by the nut 111 in
the desired position. The object of this is to permit of regulating the angle
between the winding tapes and the core tape, the box 116 having a further adjust-
ment so as to bring the tape fed through it to such an angle as is required by the
enlarged condition of the tube. 117 and 118 are the tapes which are wound upon
the supply spools located in the box 91 and are thence drawn in the same plane
but at a distance apart equal to about one half the width of the tape, so that one
tape will break joints with the other when wound. 119 is a slotted piece on the
box 115, one such piece being provided for each tape which serve to guide the
tapes to the guide-rollers 120, 121, the roller 120 being for the tape 117 and the
roller 121 for the tape 118. The tape 117 passes from the roller 120 over the top
of box 115 to and over guide-roller 122 under guide roller 123 and between
rollers 124 and 125 thence back over the boxes to be wound as above described.
Paste is applied to one side only of the tape in its passage between the rollers 124
and 125, the latter roller being covered with felt or similar substance to collect a
quantity of paste, shown by broken lines, in the box and the roller 124 being
supported in bearings in a pivotted frame to admit of adjusting the pressure
between the rollers 124 and 125. The roller 124, is smaller than 125 and by being
geared together there is a rubbing motion between them or against the tape which
smooths down the paste. 126 is the frame referred to which is three sided as
shown, the pieces forming its two opposite sides being pivottally mounted at one
end on the shaft 127 and at the other end united by a cross arm in each end of
which is a slot 128, capable of receiving the shank of an adjusting screw 129, one
end of which adjusting screw is connected to the spiral spring 130 which in turn
is secured to the side of the box, the other end of the adjusting screw being pro-
vided with a nut, the bottom of which rests on the top of the cross bar. By
adjusting this nut the space between the rollers 124 and 125 can be regulated so
that more or less paste may be applied to the tape and the tension on the tape may
also be regulated. A gear 131ª on the end of the shaft of the roller 124 drives a
similar gear on the shaft of the roller 125, the depth of the teeth of the gears being
sufficiently great to permit of considerable adjustment between the rollers 124
and 125.
As the arrangement for pasting the tape 118 is similar to the arrangement for
pasting tape 117 the various parts in both arrangements have been similarly
designated and no separate description will be given of those for tape 118.
The arrangement above referred to for automatically cutting the formed tube
into determined lengths is shewn in Figs 1, 2, 4, 5, 6 and 13.
131 is a knife mounted to rotate in a frame 132 which frame is hinged to a

page_text: rearwardly projecting lug, shown in dotted lines Fig. 6, formed on an upright-133
extending from the base plate of the bearing 39. This bearing is formed with a
groove in its bottom to slide on the dovetail rib 134 formed on the plate 135 of the
standard 136. Another standard 137 extending from the base plate of the bear-
ing 39 encircles the guide tube 34 between two flanges 138, whereby rectilinear
motion imparted to the bearing 39 will be transmitted to the guide tube 34. 139 is
the sliding support, already mentioned, for the guide tube. Cut upon the top of
this support is the longitudinal slot 140 into which is dropped a pin 141 from the
bearing 40, the purpose of the pin and slot being to permit a longitudinal move-
ment of the support for the guide tube and yet prevent any rotation thereof.
44 and 45 before referred to are other sliding supports for the guide tube having
slots 142 and 143 respectively engaging with pins 144 and 145 of the bearings 42
and 43. At the end of the support 45 is detachably secured a cup piece 146 with
a recess 147 to receive the mandrel, and recess 148 to receive the guiding tube.
This piece 146 is secured to the end of the support 45 by means of spring clip
hooks 149 and 150 secured to the support 45 catching over a lip on the cup piece
as shown. 151 is a stop having bevelled edges 152 and 153. 154 is a rope with
weight 155 attached at one end, the other end being fastened to the sliding bear-
ing 39 and running over pulley 156. The operation of the parts thus far described
in connection with the cutting apparatus is as follows:-Supposing it to bo
required to cut the tube into lengths about equal to the distance between the
rotary cutting knife and stop 151 then when the mandrel reaches the bottom of
recess 147 of the cup pieces having no outlet, it will force the cup piece along with
it, carrying the sliding supports 45, 44 and 139. The latter support being rigidly
connected to the bearing 39 will carry it along with it and us the knife frame
and support 34 are also connected to this bearing the knife and support will be
carried along with it. When the mandrel has pushed the parts far enough to
bring the inclined faces of the spring clips into contact with the bevelled edges
of the stop, the cup piece will have been projected through the opening in the
stop. A slightly further advance will raise the spring clip altogether out of
engagement with the lip on the cup piece and the latter will be pushed away from
the support 45 and will fall off. No further force tending to push the parts for-
ward, the weight will return them to their original position.
While the parts are being thus caused to travel toward the exit end of the
machine with the mandrel the rotary knife is brought into operation to cut the
material of the tube at the point determined. This is effected by locating in
the path of a finger 157 on the bearing frame of the knife a lip 158, located on
a standard rising from plate 135. The lip 158 is inclined in the direction of
the exit end of the machine to the degree required by the thickness of tube to be
cut. The finger 157 and lip 158 have reversely bevelled opposing faces. As will
be seen the knife is mounted so as to act between the ends of two sections of the
guiding tube, and is normally above the surface of the sections of the guiding tube.
Now when the mandrel pushes the knife and other parts forward, the finger 157
engaging with lip 158 will be forced under the latter and down by it, carrying
the knife down between the ends of the contiguous sections of supporting tube
onto the tube to be cut, the length of the lip being sufficient to hold the knife in
the cutting position until a complete cut is made and the inclination of the lip
being sufficient to cause the knife to cut through the tube thickness The knife
travelling longitudinally at the same speed as the tube and being rotated by it
will make a circular cut and not a spiral one.
For the purpose of regulating the depth of cut to suit different thicknesses of
tube, the standard upon which the lip 158 is mounted is provided with a vertical
slot 159 through which a set screw 160 works whereby the standard may be
vertically adjusted. To adjust the lip 158 to different diameters of tubes it is
provided with a set screw 161 working in a longitudinal slot 162 in the standard.
A coiled spring 163 opposes the downward movement of the rotary knife and
causes it to act with a yielding movement on the tube, and to rise instantly out of
the cut made when the finger 157 passes the lip 158. 164 is a pivotted spring

page_text: clip which when in the position shown in Fig. 6 prevents the rotary knife from
being turned on its hinge but when swung to one side permits the knife to be
swung back whereby access may be had to the parts in proximity to it.
Referring to Figs. 17, 18 and 19, wherein are shown views of a tube manu-
factured on the machine above described.
a, is the core of the tube which is bent into a cylinder having a seam preferably
made by abutting edges, as shown at b, Figs. 18 and 19. Preferably this core is of
paper. c, is the wrapping preferably of the same material as the core a, and
applied thereto spirally and secured by a suitable paste or cement. d, is another
wrapping, also of the same material as the core a, applied to the wrapping c,
spirally so as to break joints therewith and secured by a suitable paste or cement.
It is not deemed necessary in all cases to use more than one spiral wrapping for
the core a, one wrapping being sufficient to preserve the core in tube formation
the second wrapping being applied to secure additional strength; a third or other
wrappings may be applied for the same purpose.
The tube above described may be made, not only by the machine illustrated in
the drawings, but also by any other suitable machine or by hand, as this part of
the invention consists of the tube as a new article of manufacture.
While I regard the tube when made of paper as the better construction for
most purposes by reason of the economy, I do not limit myself to a paper tube,
as metal might be used without departing from the invention.
The tube shown herein and described withstands crushing action to such an
extent that it is not liable to collapse or lose its tubular form by any ordinary
accident and it is not liable to break, when used in lengths, from its own weight
or any ordinary weight which it may be called upon to carry.
