Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6 Bank Street,
Manchester, both in the County of Lancaster, 118, New Street, Birmingham in the
County of Warwick and 322, High Holborn in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object a machine whereby tubes of paper or cardboard
of various diameters and sections such as are generally employed in various industries.
may be manufactured entirely mechanically and automatically.
This machine is characterised by the combination of the following parts:-
A bobbin on which is wound the paper, which latter unwinds with a slight tension
by the action of the machine itself and then passes under a gumming basin where
it is impregnated with a sufficient quantity of gum; a series of spindles on which
the paper from the bobbin previously impregnated with gum is successively wound;
two cylinders which press the paper successively on each of the spindles as it is
unwound; a knife which falls under the action of a disengaging mechanism and
serves to cut the paper when the tube has reached its desired size; an indiarubber
nipper or pincer which, after the paper has been cut, serves to stick the free end
on a fresh spindle, and, finally, a series of mechanical parts which bring successively
each of the spindles into position and remove the already finished tubes.
The formation of each tube is effected on a large reel, which is composed of two
discs or checks connected together by eight crossbars each having a counterknife
on which the paper is cut. On one cheek there are fixed eight sockets or bushes
which serve as bearings or slides for spindles. On the external face of the cheek a
Maltese cross having eight branches is arranged enabling an eighth of a revolution
of the large reel to be made per revolution of a small roller.
The roll of paper having a width equal to the length which it is desired the tube
shall have is fixed on a spindle and provided with a spring brake enabling the
tension of the paper to be regulated. The paper passes over a drawing cylinder
which by means of gearings receives a circumferential speed slightly greater than
that of the cylinder of the gumming basin and assists the drawing off of the paper
as soon as there is the least tension.
The gum basin is mounted on a small independent apparatus carrying also the
drawing cylinders for the paper. The distribution of gum is regulated by means
of screws enabling the basin and a scraper to be raised or lowered; two internal
side plates serve for lateral regulation in view of the different widths of paper
employed.
Two cylinders serving to effect the winding of the paper round each of the
spindles are actuated by gearings and have a similar circumferential speed. The
upper cylinder is maintained in position during the rotation of the reel by a cam
which allows it to fall back at a suitable moment. During the winding or rolling,
the parts described are alone in action.
When the tube has reached the thickness demanded, a screw, previously adjusted

page_text: and mounted on a lever forming part of a frame bearing the lowest cylinder,
presses on a lever, which by engaging a point maintains a shaft bearing lever
cams in a ready position. When the unhooking is effected, a grip is quickly
actuated by the effect of springs; this grip carries a knife which cuts the paper
by means of counter knives. One of the parts of the paper continues to be rolled
and the other is strongly pressed on a spindle by means of the indiarubber grip
which assumes exactly its form.
The grip in its movement has carried with it the cam levers and consequently
imparted a little movement of rotation to the releasing shaft which permits the
unhooking of a lever. This lever, which is strongly drawn by a spring by over-
coming the action of another spring, effects the engagement of a small friction
device and sets in movement a shaft of cams, which shaft will make a complete
revolution and return to the starting point.
In consequence of the engagement of the small friction device its shaft is set
in movement and by means of gearings transmits its movement to the shaft of cams;
this shaft carries the roller lever of the aforesaid Maltese cross, the cam returning
the releasing shaft to its initial position, a cam operating the lever which withdraws
the spindles, and on the gearing and cams operating the engaging and disengaging
levers of the small friction device.
A cam acting on the roller lever mounted on the releasing shaft returns by the
action of a cam lever the grip to its initial position.
A roller mounted on the shaft of cams acting on the Maltese cross, formed in
one with the spindle carrying reel, causes the latter to make one-eighth of a
revolution. Before this movement of rotation of the reel, a cam has returned the
spindle to its position by means of a lever, which, by the action of this cam, itself
remains in this second position until a fresh spindle has been taken by a piston or
plunger, which lever then resumes its movement, and withdraws this spindle, which
allows the tube to fall into the receiving box.
A cam in its movement of rotation encounters a roller mounted on the end of a
lever and returns this lever to the stopping position by engaging with the point; a
small lateral projection forming part of this cam pushes a lever aside and conse-
quently disengages the lever which releases the small friction device; all the
movements depending on this friction device are then stationary, they only resume
their movement when the grip falls back by the action of the thickness of a fresh
tube.
The friction device works therefore by the action of the levers and springs placed
in the interior of this friction device.
These levers are hinged or pivoted on a spindle. The moment the first of these
levers finds itself set free, it is operated by a spring, which is more powerful than
the spring of the other lever, and it pulls the latter by means of a pin or gudgeon,
causing it thus to engage with a point; the springs of the friction device act at
this moment and engage the said friction device. "The first lever having returned
to its stopping position by the action of a cam, the other lever is only maintained
by its engagement with the point, and when it is released, the spring, being stronger
than that of the friction device, disengages this friction device by means of a roller
mounted on the said lever.
The machine works in the following way :-
A bobbin or roll of paper mounted on the spindle is unwound, and passed over
the drawing cylinder, then over the cylinder which bears the gumming basin, then
over a guide and is finally wound on a spindle or mandrel by the action of the two
cylinders bearing thereon, having a rotating movement and acting by spring pressure
on the spindle as has been hereinbefore described. When the tube has reached the
desired size, a disengaging gear causes a knife to fall and cut the paper, thus
limiting the diameter of the tube, and the action of a caoutchouc grip causes the
other part of the paper to stick on a new spindle.
At the falling of the knife, the parts hereinbefore described commence to operate
and consequently the spindle is returned to its position in the large reel; the knife

page_text: by the action of cam levers returns to its initial position. The large reel bearing
the spindles or mandrels and actuated by the Maltese cross then describes one-
eighth of a revolution. The paper well pressed on the spindle by the action of the
grip adheres thereon and passes between two winding on cylinders for the manu-
facture of a fresh tube.
In order to facilitate this transfer, a little movement of rotation is imparted from
the reel to the spindle on which the paper sticks, which paper is wound for the first
revolution. For this purpose the extremity of each spindle is polished and bears
on a fixed sector which is also polished.
The spindles, having advanced from one position, a piston, operated by a lever,
engages the spindle and withdraws it entirely from the tube, which latter falls into
the receiving box. When the lever arrives at the end of its course, all the parts
set in movement by the falling of the knife come to a standstill, and the rolling of
the paper only at this moment remains in action.

I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6 Bank Street, Manchester,
both in the County of Lancaster, 118 New Street, Birmingham, in the County of
Warwick, and 322, High Holborn in the County of Middlesex, Civil Engineer, 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:-
This invention has for its object a machine whereby tubes of paper or cardboard
of various diameters and sections such as are generally employed in various
industries may be manufactured entirely mechanically and automatically.
This machine is characterised by the combination of the following parts:-
A bobbin on which is wound the paper, which latter unwinds with a slight
tension by the action of the machine itself and then passes under a gumming basin
where it is impregnated with a sufficient quantity of gum; a series of spindles on
which the paper from the bobbin previously impregnated with gum is successively
wound; two cylinders which press the paper successively on each of the spindles as it is
unwound; a knife which falls under the action of a disengaging mechanism
and serves to cut the paper when the tube bas reached its desired size; an india-
rubber nipper or pincer which, after the paper has been cut, serves to stick the free
end on a fresh spindle, and finally, a series of mechanical parts which bring
successively each of the spindles into position and remove the already finished
tubes.
In order to facilitate the description of the invention, reference will be had to

Figures 12 and 13 show the means enabling the knife C to be disengaged and
show the knife in full lines;
Figure 14 shows an elevation in detail of the parts and means serving for
withdrawing the mandrels and returning them.
The same reference letters represent the same parts in the various figures.
The formation of each tube is effected on a large reel, which is composed of two
dises or cheeks D and D' (Figures 1, 2, 3 and 8) connected together by eight
crossbars E-E each having a counterknife N-N on which the paper is cut.
On one cheek D there are fixed eight sockets or bushes O (Figure 3) which serve
as bearings or slides for spindles B-B'. On the external face of the disc or
cheek Da Maltese cross D (Figures 7 and 8) having eight branches is arranged
enabling an eighth of a revolution of the large reel to be made per revolution of a
small roller.
The roll of paper having a width equal to the length which it is desired the tube
shall have is fixed on a spindle A (Figure 1) and provided with a spring brake P
enabling the tension of the paper to be regulated. The paper passes over a drawing
cylinder A which by means of gearings H H receives a circumferential speed
slightly greater than that of the cylinder A of the gumming basin and assists the
drawing off of the paper as soon as there is the least tension.
The gum basin G is mounted on a small independent apparatus carrying also
the drawing cylinders A A' for the paper. The distribution of gum is regulated
by means of screws 9 enabling the basin and a scraper gl to be raised or
lowered; two internal side plates g and g (Fig. 2) serve for lateral regulation
in view of the different widths of paper employed.
Two cylinders C, C¹ serving to effect the winding of the paper round each
of the spindles are actuated by gearings 1-9 (Figures 1 and 3) and have a
similar circumferential speed. The upper cylinder C is maintained in position
during the rotation of the reel D, by a cam U, (Figs. 1 and 9) which allows it
to fall back at a suitable moment. During the winding or rolling, the parts
described are alone in action.
When the tube has reached the thickness demanded, a screw I, previously
adjusted and mounted on a lever T forming part of a frame I' bearing the
lowest cylinder, (Figs. 1, 2, & 9) presses on a lever 12, (Figs. 10, & 11) which
by means of a hook 1 normally maintains a shaft 1 bearing lever cams Cin
a ready position. An unhooking or disengaging is thus effected, and a grip C
(Figs. 12 & 13) is quickly actuated by the effect of springs C; this grip carries a
knife C which cuts the paper by means of counter knives N. The cut-off piece of
paper continues to be rolled whilst the end of the web is held strongly pressed
on a spindle B' by means of the indiarubber grip C which assumes exactly its
form.
The grip in its movement has carried with it the cam levers C (Fig. 12) and
consequently imparted a little movement of rotation to the releasing shaft I which
permits the unhooking or disengaging of a lever 15 (Figures 2, 3 and 4 and more
clearly in Fig. 6). This lever, which is strongly drawn by a spring i (Fig. 2) by
overcoming the action of another spring i", effects the engagement of a small friction

page_text: clutch device J whereby the cam shaft K is operated in the following manner &
caused to make a complete revolution and return to the starting point.
In consequence of the engagement of the small friction device J, its shaft K' is
set in movement and by means of gearings K2 K3 (Fig. 6) transmits its movement
to the cam shaft K. This shaft carries the following parts :-A roller lever K
(Figs. 8 & 10) which engages the aforesaid Maltese cross; a cam C (Fig. 10)
which returns the releasing shaft 1 to its initial position; a cam K (Fig. 14)
which operates the lever F which withdraws the spindles; and the gearing K and
cams K and K (Figure 4) which operate the engaging and disengaging levers of
the small friction device.
A cam C (Fig. 10) acting on the roller lever C', mounted on the releasing
shaft I, returns, by the action of the cam lever C (Fig. 12) the grip C³ to its
initial position.
The roller K (Figs. 7 & 8) mounted on the shaft of cams and acting on the
Maltese cross D, which is formed in one with the spindle carrying reel D, causes
the latter to make one-eighth of a revolution. Before this movement of rotation of
the reel, the cam K (Fig. 14) has returned the spindie B2 to its position
by means of a lever F, which, by the action of this cam, itself remains in this
second position until a fresh spindle has been taken by a piston or plunger F, which
lever then resumes its movement, and withdraws this spindle, which allows the tabe
to fall into the receiving box.
The cam K (Fig. 6) in its movement of rotation encounters a roller K' mounted
on the end of the lever 15 and returns this lever to the stopping position in which
it is retained by a catch '; a small lateral projection K (Fig. 4) forming part of
this cam pushes a lever L aside and consequently disengages the lever I which
releases the small friction device J; all the movements depending on this friction
device are then stationary, they only resume their movement when the grip falls
back by the action of the thickness of a fresh tube.
The friction device J works therefore by the action of the levers 1 1 and
springs placed in the interior of this friction device.
These levers 1 1 (Fig. 6) are hinged or pivoted on a spindle M. The moment
the first of these levers finds itself set free, it is operated by a spring i (Fig. 2),
which is more powerful than the spring of the lever 1, and it pulls the latter by
means of a pin or gudgeon 18, causing it thus to engage with a point ; the
springs of the friction device J act at this moment and cause the said friction
device to engage. The first lever I having returned to its stopping position by the
action of the cam K, the other lever I is only maintained by its engagement with
the point, and when it is released, the spring i, being stronger than that of the
friction device, disengages this friction device by means of a roller m mounted on
the said lever.
The machine werks in the following way :-
A bobbin or roll of paper mounted on the spindle A is unwound, and passed over
the drawing eylinder A', then over the cylinder A which bears the gumming
basin, then over a guide A and is finally wound on a spindle or mandrel B by the
action of the two cylinders C and C' bearing thereon, having a rotating movement
and acting by spring pressure on the spindle as has been hereinbefore described.
When the tube has reached the desired size, a disengaging gear causes a knife C
(Figs. 12 & 13) to fall and cut the paper, thus limiting the diameter of the tube
and the action of a caoutchouc grip C³ causes the other part or end of the web of
paper to stick on to a new spindle.
At the falling of the knife, the parts hereinbefore described commence to
operate and consequently the spindle B2 is returned to its position in the large
reel D; the knife by the action of cam levers C, C returns to its initial position.
The large reel D bearing the spindles or mandrels and actuated by the Maltese
cross D then describes one-eighth of a revolution. The paper well pressed on
the spindle B' by the action of the grip C adheres thereon and passes between
two winding-on cylinders for the manufacture of a fresh tube.

page_text: mate this transfer, a little movement of rotation is imparted fr
the reel to the spindle on which the paper sticks, which paper is wound for
first revolution. For this purpose the extremity 6 of each spindle is milled (Fig.
and bears on a fixed sector S (Fig. 1) which is also milled."
The spindles B' B2 having advanced from one position, a piston F, operated
a lever F, engages the spindle B2 and withdraws it entirely from the tube, whi
latter falls into the receiving box F. When the lever F arrives at the end
its course, all the parts set in movement by the falling of the knife come to
standstill, and the rolling of the paper only at this moment remains in action.
The forms, dimensions, proportions and accessory parts may of course be vari
and any materials deemed suitable may be employed in their manufacture.
Having now particularly described and ascertained the nature of the said inve
tion and in what manner the same is to be performed as communicated to me b
my foreign correspondents, I declare that what I claim is :-

and a counterknife serving to cut the paper when the tube has attained the desired
size, of an indiarubber grip, serving, after the paper has been cut, to stick its free
end onto a fresh spindle, and finally of a series of mechanical parts adapted to
bring each of the spindles successively into position and to remove the tubes
already formed, substantially as herein before described and shown as an example
in the accompanying drawings.
