New or Improved Mechanism for Applying Paraffin to Cigarette
Paper in Cigarette-making Machines.
I, ALFRED CHARLES MARCHAL, Managing Director of La Société Anonyme
des Usines A. E. Decouflé, of 8 Rue Roger, Paris, in the Republic of France, do
hereby declare the nature of the said invention to be as follows :-
The object of this invention is to apply the paraffin to the cigarette paper in
cigarette making machines as the manufacture of the cigarettes goes on.
The
invention consists of special arrangements of mechanism whereby the automatic and
absolutely regular application of the paraffin.is effected to each and every cigarette
manufactured.
This mechanism when applied to what is known as the Decouflé machine for
making cigarettes without adhesive material may be operated by the mechanism
which actuates the printing stamp of the controlling mark; but it may also be
applied to Decouflé or other cigarette machines whether the cigarette tubes are
pasted or not, and it may be operated directly or indirectly from the cam shaft or
any other suitable moving part of the machine.
In the well known Decouflé machines the support of the fork in which the
bobbin of paper is mounted is usually fixed on a prolongation of the table on which
the stamping and other devices are placed. On the said prolongation I fix the
support of a cistern, containing the paraffin, inside of which is, a polygonal rotating
drum, say one of eight sides for example, carried by an axis on which is fixed a
ratchet wheel of the same number of teeth as there. are sides to the drum, into
which teeth takes a pawl mounted on a lever secured on an axis having a rocking
or oscillating motion and which transmits the well known movements to the
controlling or other distinctive stamp.
The ratchet wheel on the axis of the drum is held in proper position by a
retaining pawl or lever acted on by a suitable spring. The acting end of the
retaining pawl or lever is furnished with a roller to reduce as much as possible the
friction of the pawl on the teeth of the ratchet wheel.
The printing stamp is mounted on the upper end of a slide which has in it a slot
or mortice into which takes the end of a lever secured on the above mentioned
rocking axis.
The vertical slide of the stamp is provided at its lower part with a stud carrying
a friction roller which comes in contact with a lever pivotted on a stud secured to a
fixed part of the machine. Connected with the said lever is an arm which forms
the paraffining pad and which is covered with indiarubber on its acting part. A
spring acts on the said lever so as to press its lower end constantly against the
roller on the stamp slide and to raise the paraffining pad when it is to remain out
of action.
A scraper bears constantly against the flat faces of the aforesaid drum to equalize
the paraffin thereon before the same is applied to the paper.
The cigarette paper is rolled up as usual round the paper bobbin, the axis of
which turns in the branches of the usual supporting fork. This paper is unrolled
by the ordinary well known feeding forward mechanism and is led over a guide
roller before passing between the faces of the aforesaid drum and pad.
In order to reduce the space occupied by the cigarette machine, I make the
support and fork of the paper bobbin in line with each other and place them imme-
diately behind the stamping and paraffining devices. In this case the paper, ou leaving
the bobbin, passes round a guide roller which is mounted at the end of a lever

page_text: pivotted to the aforesaid prolongation of the table of the machine. A spring acts
on this lever to impart the requisite tension to the paper.
In another arrangement, the paper passes over two guide rollers and the support
of the paper bobbin fork is fixed at the end of the prolongation of the table in front
of the stamping and paraffining devices.
In another arrangement the paper bobbin fork is a straight prolongation of the
support, and the paper in unrolling from the bobbin passes over two guide rollers
before entering between the drum and the pad. One of these guide rollers is
carried by a bell crank lever pivotted to the paper bobbin fork and acted on by a
spring to secure the tension of the paper.
It will now be understood that after each movement forward of the paper, the
stamping and paraffining mechanism is brought into action in the following way:-
When the slide of the stamp is raised by its lever, the roller on its lower end rises
at the same time, and causes the lever of the paraffining pad to oscillate on its pivot.
This is thereby lowered and presses the paper against that face of the drum which
happens to be uppermost; the paper is thereby paraffined, and when the slide
descends the paper rises with the pad. In the downward movement of the slide
and lever, the pawl operates the ratchet wheel on the axis of the drum and turns it
one eighth of a revolution so that a fresh face of the drum is brought uppermost
for the next paraffining operation. During the partial rotation of the paraffining
drum the paper is moved forward by the usual feeding devices.
The cutting off of the paper, when it is formed into a tube, is effected either at
the edge of the transverse band of paraffin, or at the middle thereof according as
the cigarettes are to be paraffined at one or both ends.
Instead of the cistern being fixed on the prolongation of the table and the pad
'being made movable, the pad may be fixed and the cistern with its drum be moved
up and down to produce the desired effect upon the paper.
It is obvious that the automatic paraffining devices above described may be
modified to suit any other kind of machine for manufacturing cigarettes whether
with pasted or non-pasted tubes, besides that known as the Decouflé which I have
referred to more especially by way of example.

New or Improved Mechanism for Applying Paraffin to Cigarette
Paper in Cigarette-making Machines.
I, ALFRED CHARLES MARCHAL, Managing Director of La Société Anonyme
des Usines A. E. Decouflé of 8 Rue Roger, Paris, in the Republic of France, 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, that is to say :-
The
The object of this invention is to apply the paraffin to the cigarette paper in'
cigarette-making machines as the manufacture of the cigarettes goes on.
invention consists of special arrangements of mechanism whereby the automatic and
absolutely regular application of the paraffin is effected to each and every cigarette
manufactured.
This mechanism, when applied to what is known as the Decouflé machine for
making cigarettes without adhesive material, may be operated by the mechanism
which actuates the printing stamp of the controlling mark, but it may also be
applied to Decouflé or other cigarette machines, whether the cigarette tubes are

page_text: from the cam shaft or any other suitable moving part of the machine.
In the drawings hereto annexed
Figure 1 is an elevation of the mechanism for applying the paraffin adapted to
the entering end of a Decouflé cigarette machine for making cigarettes without
paste or other adhesive material.
Figure 2 is a side view, being a projection of Figure 1.
Figure 3 is a side view showing two arrangements of support for the paper
bobbin, and
.
Figures 4, 5, 6 & 7 are detail views of the paraffining pad and of parts connected
therewith.
In the well know Decouflé machines the support p² of the fork p³, in which the
bobbin of paper p is mounted, is usually fixed on a prolongation of the table on
which the stamping and other devices are placed. On the said prolongation g
I fix the supports of a cistern a, containing the paraffin, inside of which cistern is
a polygonal rotating drum b (say one of eight sides for example) carried by an
axis on which is fixed a ratchet wheel c of the same number of teeth as there
are sides to the drum into which teeth takes a pawl d mounted on a lever d' secured
on an axis having a rocking or oscillating motion and which transmits the well
known movements to the controlling or other distinctive stamp.
The ratchet wheel c, on the axis of the drum, is held in proper position by a
retaining pawl or lever e pivotted at e¹ and acted on by a suitable spring e. The
acting end of the retaining pawl or lever e is furnished with a roller e³ to reduce as
much as possible the friction of the pawl e on the teeth of the ratchet wheel (.
The printing stamp is mounted on the upper end of a slide t which has in it a
slot or mortise T into which takes the end of a lever t¹ secured on the above
mentioned rocking axis f. Figure 1, 6 and 7 show that the lever d' of the pawl d
is secured to the lever t' of the stamp, but it will be understood that these
levers d'' may be made separate and both fixed on the same shaft f.
The vertical slide t of the stamp is provided at its lower part with a stud g¹
carrying a friction roller 9 which comes in contact with a lever i pivotted on a
stud secured to a fixed part of the machine. Connected with the said lever i
is an arm which forms the paraffining pad and which is covered with indiarubber
on its acting part. A spring k acts on the said lever i so as to press its lower end
constantly against the roller g on the stamp slide and to raise the paraffining pad
when it is to remain out of action.
A scraper, fixed on the end of a flexible blade r³, bears constantly against the
flat faces of the aforesaid drum to equalize the paraffin thereon before the same
is applied to the paper.
The cigarette paper p is rolled up as usual round the paper bobbin o the axis o¹
of which turns in the branches of the usual supporting fork p³. This paper is
unrolled by the ordinary well known feeding forward mechanism, and is led over a
guide roller before passing between the faces of the aforesaid drum b and
pad h.
In order to reduce the space occupied by the cigarette machine I make the
support pland fork p² of the paper bobbin in line with each other and place them
immediately behind the stamping and paraffining devices. In this case the paper,
on leaving the bobbin, passes round a guide roller which is mounted at the end of
a lever pivotted at of to the aforesaid prolongation q of the table of the machine.
A spring acts on this lever v' to impart the requisite tension to the paper p.
In another arrangement, shown in Figure 3, the paper passes over two guide
rollers n n', and the support p¹ of the paper bobbin fork pi is fixed at the end of
the prolongation y of the table in front of the stamping and paraffining devices.
In another arrangement, shown by dotted lines in Figure 3, the paper bobbin
fork p is a straight prolongation of the support p', and the paper, in unrolling from
the bobbin, passes over and under the guide rollers mm' before entering between the
drum 6 and the pad h. One of these guide rollers m is carried by a bell-crank

page_text: :
lever m² pivotted at m³ to the paper bobbin fork p³ and acted on by a spring m* to
secure the tension of the paper.
It will now be understood that after each movement forward of the paper the
stamping and paraffining mechanism is brought into action in the following way :-
When the slide t of the stamp is raised by its lever t', the roller g on its lower end
rises at the same time, and causes the lever i of the paraffining pad h to oscillate on
its pivot it. This pad is thereby lowered and presses the paper p against that
face of the drum 6 which happens to be uppermost; the paper is thereby paraffined,
and when the slide t descends the paper rises with the pad h. In the downward
movement of the slide t and lever t' the pawl d operates the ratchet wheel c on the
axis of the drum b and turns it a part of a revolution so that a fresh face of the
drum is brought uppermost for the next paraffining operation. During the partial
rotation of the paraffining drum & the paper is moved forward by the usual feeding
devices.
The cutting off of the paper, when it is formed into a tube, is effected either at
the edge of the transverse band of paraffin, or at the middle thereof according as
the cigarettes are to be paraffined at one or both ends.
Instead of the cistern a being fixed on the prolongation q of the table and the
pad h being made movable, the pad may be fixed and the cistern a, with its drum b,
be moved up and down to produce the desired effect upon the paper.
It is obvious that the automatic paraffining devices above described may be
modified to suit any other kind of machine for manufacturing cigarettes whether
with pasted or non-pasted tubes besides that known as the Decouflé which I have
referred to more especially by way of example.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
First. In a cigarette-making machine, mechanism for applying paraffin to the
cigarette paper, said mechanism consisting of a paraffin cistern, a polygonal drum
contained in the said cistern, a pad for pressing the paper against the faces of the
drum and mechanism for imparting step by step rotatory movements to the drum,
and intermittent up and down movements to the pad, substantially as described.
Second. In a cigarette-making machine, mechanism for applying paraffin to the
cigarette paper consisting of a paraffin cistern a, a polygonal drum b contained in
the said cisteru, a pad h for pressing the paper against the faces of the said drum,
ratchet pawl.and lever devices for imparting step by step rotatory movements to
the said drum b from the rocking shaft f which transmits motion to the controlling
or other distinctive stamp and devices for imparting intermittent up and down
movements to the said pad h from the stamping mechanism, substantially as
: described.
