Improved Machine for Filling the Paper-tubes of Cigarettes with
Tobacco.
We, GUSTAF ADOLF HAGELBERG, of Eriksgatan 7, Helsingfors, Finland, Notary
to Supreme Court, and LEONARD LINDELÖF, of Konstantinsgatan 25, Helsingfors,
Finland, Professor, do hereby declare the nature of this invention to be as
follows:-
-
The present invention relates to a machine for filling the ready made paper-
tubes of cigarettes with tobacco, which either by hand or by some mechanical
arrangement is fed forward in a string of uniform thickness and of an area of cross
section equal to or somewhat less than that of the cigarette in process of making,
on to a travelling belt which transports it to the vicinity of the forming-tube,
whereupon a slide moving across the belt by means of a cutter cuts of a
piece of the string corresponding to the length of the cigarette, which piece is
pushed aside from the belt by the slide, to be subsequently enclosed in the form-
ing-tube by means of the aforesaid slide or by other arrangement, from which
forming tube a plunger in usual manner inserts the tobacco in the paper tube
previously fed forward to the forming tube by means of a feeding-arrangement
while the paper-tube is being held stationary by means of a clamping-device.
Compared with machines previously used for the same purpose, the present
machine possesses the advantage that the fibres of tobacco remain uninjured as far
as is possible, inasmuch as no cutting takes place in the longitudinal direction of
the cigarette, the cigarettes as a consequence having such strength that in shaking
them no tobacco runs out, and, in view of the fact that no longitudinal com-
pression of the string can take place until the tobacco has become enclosed in the
forming-tube, any stoppage in the latter as well as the formation of hard-packed
lumps in the tobacco are excluded, the cigarettes delivered by the machine,
therefore, being quite uniformly filled.
The invention is illustrated in the accompanying drawing showing a machine
arranged in the manner mentioned.
Fig. 1 represents a front-elevation of the machine;
Fig. 2 shows a top view of the machine:
Fig. 3 a section of the same on lines ab (Fig. 1) looking to the right.
Fig. 4 a section on lines b-c, (Fig. 1) looking to the left;

Fig. 6 another detail.
In Figs. 1 and 2 the table 88 situated above the machine is omitted.
All the parts of the machine are mounted on the base-plate 1 on which are located
pedestals 2 and 3 for supporting the main-shaft 4 of the machine, said shaft
rotating in the direction indicated by the arrow. On this shaft the following
parts are mounted, viz., the pinion 5, the coupling or ratchet disc 6 and the
sleeve 7 which are rigidly connected to each other and can revolve
on the

page_text: shaft 4, the sleeve 8 which is connected with the shaft and has a coupling pawl 9
by means of which the sleeve 7 is periodically coupled to the shaft 4, the grooved
cam 10 and cam 11 which produce the reciprocating motion of the cutting off
slide 12 and the upward motion of slide 13, the disc 14 with the crank pin 15
fixed in it for giving motion to the plunger, and finally the cam 16 for giving the
required motion to the clamps or gripping holders 17. The pinion 5 meshing
with the gear 21 on the shaft 18, which is journalled in the boxes 19 and 20,
turns the gear wheel 21 together with the shaft 18 and the belt pulley 22 in the
direction of the arrow when the pinion 5 is coupled to the shaft 4. The belt 27
is thus given a periodical motion which by means of the belt pulley 28, shaft 29,
bevel gears 30, 31 and 32, 33 and belt pulleys 34 and 35 is transmitted to the
belts 36 and 37, so that the belts 27, 36, and 37 will simultaneously move in the
direction of the arrows and at the same rate of speed.
The coupling of the pinion 5 to the shaft '4 and its disconnecting therefrom is
accomplished by the pawl 9 being forced against the ratchet disc 6 by the action
of the spiral spring 23, thus compelling the said ratchet disc to revolve with the
shaft 4 so long as the pawl is not held out of contact with the said ratchet disc (
by the arc-shaped pieces 25 and 26 which cause a slight rearward movement of
the end 24 of said pawl which is provided with a roller. The said piece 26'can
be shifted with relation to piece 25 and by this means the moment of disengage-
ment of pinion 5 from shaft 4 can be regulated.
With the curved groove 38 of the cam 10 engages the lever 40,- which is
supported by and pivoted on the post 39, so that the slide 12 is given a recipro-
cating motion. This motion can be accurately adjusted by means of the
screw 42. On the cam 11 presses one end of the lever 44, which end is provided
with a roller 43, said lever being fulcrumed on the shaft 18 and by means of
its opposite forked end embracing the pin 15 which is fixed to the slide 13, so
that the said slide 13 is moved upward when the swell of the cam 11 is in contact
with the roller 43. The slide 13 is given its return motion by means of the
spiral spring 47 attached to the arm 46. The slides 12 and 13 are supported on
and slide on the support 48. The belt 27 passes above the upper surface of the
latter piece and beneath the slide 12. The slide 13 is provided with a knife-
edge 49 cooperating with the knife 50 which is fixed to support 48.
To the slide 13 is attached the piece 51 which has a semi-cylindrical cavity at
the edge and together with the semi-cylindrical bottom of the piece 52 forms the
tube 53. The continuation of this tube is formed by the tube 54 which is cut off
obliquely and in which the plunger 55 reciprocates periodically. The plunger 55
is a prolongation of the rod 56 which is supported in the boxes 57 and 58. The
rod 56 and plunger 55 receive their reciprocating motion by means of the con-
necting piece 59 which rigidly connects the rod 56 with the rod 62 supported by
the boxes 60 and 61 and moving therein, said rod in its turn being rigidly united
to the piece 63 in the slot 64 of which the crank-pin 15 enters and the piece 63
being given a motion to and fro which is interrupted during the space of time
when the pin 15 passes through the distance e-f of the slot 64.
65 is a roller provided with longitudinal grooves 66, said roller periodically
rotating and reciprocating longitudinally and having for its function to feed
forward the empty paper-tubes to the aforesaid forming-tube and to return and
deliver them when filled. It can be shifted longitudinally on the shaft 67 but
cannot turn on the latter and it is divided in two parts a and b the latter of
which can be moved away slightly from the former as the lengths of the paper-
tubes require. The grooves 66 terminate at a place 68 perpendicular to the
shaft 67. The roller 65 is given its rotating motion by a kind of rack consisting
of two pins 69. attached to the slide 13 and in the upward motion of said slide
engaging with the gear 70 fixed to the shaft 67 and provided with 8 teeth, said
rack carrying the gear together with the shaft 67 and roller 65 a quarter of a
revolution forward. When the slide 13 returns, the shaft is prevented from
rotating by means of a pawl engaging with the gear 70. The pins 69 in this

page_text: return-motion slide over the teeth of gear 70 in consequence of the fact that the
connecting piece 71 is composed of a spring.
The reciprocating motion of roller 65 is derived from the rod 62, being pro-
duced by the stop-collars 71 and 72 on the latter, which collars in the motion of
the rod strike again the piece 73, the other end of which embraces an extension
of the roller 65, said extension consisting of a sleeve which can turn but not be
shifted in the piece 73. The arrangement for holding the paper-tubes fast to
the tube 54 while they are being filled with tobacco (which arrangement, as
already mentioned, derives its motion from the main shaft 4 by means of the
cam 16) consists of two clamps or grippers 17 pivoted on the pins 74 and 75 and
covered at their ends with rubber while their opposite ends g' are connected by
means of a spiral spring 76 striving to hold the ends i removed from the tube.
When the wedge shaped piece 77 enters into the square aperture 78 formed by a
groove in each gripper, these ends of the grippers are separated and the opposite,
and the covered ends f are pressed against the tube and thus retain the paper-tube
slid over it. When the piece 77 returns, the paper-tube is released by the
grippers. The piece 77 and grippers 17 derive their motion from the cam 16 on
the main shaft 4 by means of the arm 79 attached to the piece 77 and rigidly

connected to the shaft 82 which is journalled in the boxes 80 and 81.
is provided at its other end with another arm 83 actuated by the lever 84
rotatably mounted on the shaft 85 and provided at the other end with a roller 86
sliding on the cam 6. The end of the lever 84 is always kept pressed against the
cam by means of spiral spring.
The machine operates as follows:
The trough formed by the belts 27, 36 and 37 is filled with tobacco. By the
motion of the belts the string of tobacco is fed forward while resting on the
belt 27 and finally enters between the edges of the knives 49 and 50 in front of
the slide 12. The moment the motion of the belts ceases, the slide 12 is set in
motion the string of tobacco is cut off between the edges 49 and 50, and the
tobacco thus cut off is pushed by the slide 12 from the belt in under the slide 13.
When the
The slides 12 and 13 now occupy the position shown in Fig. 5.
slide 13 subsequently commences to move downward, the piece 51 depresses
the tobacco into the aperture and by closing the latter forms the tube 53. The
slide 12 remains in the position shown in Fig. 5 until the piece 51 has passed
the belt 27 when it returns to its former position. As soon as it has reached this
position, the belts again resume their motion. When the slide 13 has reached
its lowermost position, the plunger is set in motion and pushes in front of it the
tobacco enclosed in the tube.
In the preceding rearward motion of the plunger, one of the papertubes resting
in the grooves of the roller 65 has been slid over the tube 54 and it is retained
there by the grippers 17 which have been drawn together at the time when the
plunger remained stationary in its extreme position to the right. When the
tobacco has become inserted sufficiently. far into the paper-tube, the grippers
release the latter which by the continued motion of the slide is moved away from
the tube 54, accompanying the roller 65 in its motion. Simultaneously with the
subsequent receding movement of the plunger the slide 13 moves upward, and
the roller 65 at the same time, before being shifted longitudinally, rotates a
quarter of a revolution, delivers the filled paper-tube and receives a fresh empty
tube. The same series of operations is repeated in each revolution of the shaft 4.

We, GUSTAF ADOLF HAGELBERG, of Eriksgatan 7, Helsingfors, Finland, Notary
to Supreme Court, and LEONARD LINDELOF, of Konstantinsgatan 25, Helsingfors,
Finland, Professor, 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:-
The present invention relates to machines for filling the ready made paper-
tubes of cigarettes with tobacco.
In our machine the tobacco is, either by hand or by some mechanical means,
fed forward in a string of uniform thickness and of an area of cross section
equal to or somewhat less than that of the cigarette in process of making, on
to a travelling belt which transports it to the vicinity of a forming-tube, whereupon
a slide moving across the belt by means of a cutter cuts off a piece of the string
corresponding to the length of the cigarette, which piece is pushed aside from
the belt by the slide, to be subsequently enclosed in the forming-tube by means
of the aforesaid slide or by other arrangement, from which forming-tube a
plunger in usual manner inserts the tobacco in the paper-tube previously fed
forward to the forming tube by means of a feeding-arrangement while the paper-
tube is being held stationary by means of a clamping-device. Compared with
machines previously used for the same purpose, the present machine possesses the
advantage that the fibres of tobacco remain uninjured as far as is possible, inas-
much as no cutting takes place in the longitudinal direction of the cigarette, the
cigarettes as a consequence having such strength that in shaking them no
tobacco runs out, and, in view of the fact that no longitudinal compression of
the string can take place until the tobacco has become enclosed in the forming-
tube, any stoppage in the latter as well as the formation of hard-packed lumps
in.the tobacco are prevented, the cigarettes delivered by the machine, therefore,
being quite uniformly filled."
The invention is illustrated in the drawings filed with the Provisional Specifi-
cation showing a machine arranged in the manner mentioned.
Fig. 1 represents a front-elevation of the machine;
Fig. 2 is a top-view of the machine;
Fig. 3 is a sectional-view of the same on lines a-b in Fig. 1, looking to the
right.

Figs. 7 and 8 filed with this Specification shew further details of the mechanism.
In Figs. 1 and 2 the table 88 situated above the machine is omitted.
The machine is mounted on the base-plate 1 on which are located
pedestals 2 and 3 for supporting the main-shaft 4 of the machine, said shaft
rotating in the direction indicated by the arrow. On this shaft the following
parts are mounted, viz., the pinion 5, the coupling or ratchet disc 6 and the
sleeve which are rigidly connected to each other and can revolve
shaft 4, the sleeve 8 which is connected to the said shaft and has a coupling
on the
pawl 9 by means of which the sleeve · 7

shaft 4, a grooved cam 10, and

duce the reciprocating motion of a cutting off slide 12 and the upward motion of a
which pro-
slide 13, a disc 14 with a crankpin 15 fixed in it for giving motion to a plunger,

page_text: and finally a cam 16 for giving the required motion to clamps or gripping
holders 17. The pinion 5 meshing with the gear 21 on the shaft 18, which is
journalled in the boxes 19 and 20, and provided with a belt-pulley 22, turns said
gear wheel 21, shaft 18, and belt pulley 22 in the direction of the arrow when
the pinion 5 is coupled to the shaft 4. The belt 27 is thus given a periodical
motion which by means of the belt pulley 28, shaft 29, bevel-gears 30, 31
and 32, 33 and belt pulleys 34 and 35 is transmitted to the belts 36 and 37, so
that the belts 27, 36, and 37 will simultaneously move in the direction of the
arrows and at the same rate of speed, the ratio of gearing being suitable for the
purpose.
The coupling of the pinion 5 to the shaft 4 and its disconnecting therefrom is
accomplished in the following manner: The spiral spring 23 tends to keep the
pawl in engagement with the ratchet disc 6, whereby the said disc 6 and the
pinion 5, which is firmly connected therewith, are forced to rotate with the
axle 4, as long as the pawl 9 is not kept away from the ratchet disc 6 by the
arc-shaped pieces 25 and 26 striking against the roller 24. Said roller 24 is
placed on the outer end of the pawl 9, and will when it passes the arcs 25 and 26
be pushed back by them. The position of the piece 26 may be adjusted in relation
to the piece 25, so that the uncoupling of the pinion 5 will take place at the
right time.
With the curved groove 38 of the cam 10 engages the lever 40, which is
supported by and pivoted on the post 89, so that the slide 12 is given a recipro-
cating motion. This motion can be accurately adjusted by means of the
screw 42. On the cam 11 presses one end of the lever 44, which end is provided
with a roller 43, said lever being fulcrumed on the shaft 18 and by means of
its opposite forked end embracing the pin 45 which is fixed to the slide 13, so
that the said slide 13 is moved upward when the swell of the cam 11 is in contact
with the roller 43. The slide 13 is given its return motion by means of the
spiral spring 47 attached to the arm 46. The slides 12 and 13 are supported
and slide on the support 48. The belt 27 passes above the upper surface of the
latter piece and beneath the slide 12. The slide 13 is provided with a knife-
edge 49 cooperating with the knife 50 which is fixed to the slide 12.
To the slide 13 is attached the piece 51 which has a semi-cylindrical cavity at
the edge and together with the semi-cylindrical bottom of the piece 52 forms the
tube 53. The continuation of this tube is formed by the tube 54 which is cut off
obliquely and in which a plunger 55 reciprocates periodically. The plunger 55
is a prolongation of the rod 56 which is supported in the boxes 57 and 58. The
rod 56 and plunger 55 receive their reciprocating motion by means of the con-
necting piece 59 which rigidly connects the rod 56 with the rod 62 supported by
the boxes 60 and 61 and moving therein, said rod in its turn being rigidly united
to the piece 63 in the slot 64 of which the crank-pin 15 of the crank-disc 14
enters and the piece 63 being given a motion to and fro which is interrupted
during the space of time when the pin 15 passes through the curved part e-f
of the slot 64.
65 is a roller provided with longitudinal grooves 66, said roller periodically
rotating and reciprocating longitudinally and having for its function to feed
forward the empty paper-tubes to the aforesaid forming-tube 54 and to return and
deliver them when filled. It can be shifted longitudinally on the shaft 67 but
cannot turn on the latter and it is divided in two parts a and b the latter of
which can be moved away slightly from the former as the lengths of the paper-
tubes require. The grooves 66 terminate at a place 68 perpendicular to the
shaft 67. The roller 65 is given its rotating motion by a kind of rack consisting
of two pins 69 attached to the slide 13 and in the upward motion of said slide
engaging with the gear 70 fixed to the shaft 67 and provided with 8 teeth, said
rack carrying the gear together with the shaft 67 and roller 65 a quarter of a
revolution forward. When the slide 13 returns, the shaft is prevented from
rotating by means of a pawl engaging with the gear 70. The pins 69 in this

page_text: return-motion slide over the teeth of gear 70 in consequence of the fact that the
connecting piece 71 is composed of a spring.
The reciprocating motion of the rolier 65 is derived from the rod 62, being pro-
duced by the stop-collars 71 and 72 on the latter, which collars in the motion of
the rod strike again the piece 73, the other end of which embraces an extension
of the roller 65, said extension consisting of a sleeve which can turn but not be
shifted in the piece 73. The arrangement for holding the paper-tubes fast to
the tube 54 while they are being filled with tobacco (which arrangement, as
already mentioned, derives its motion from the main shaft 4 by means of the
cam 16) consists of two clamps, (shown in Fig. 6) or grippers 17 pivoted on the
pins 74 and 75 and covered at their ends with rubber while their opposite ends k
are connected by means of a spiral spring 76 tending to hold the ends i removed
from the tube. When the wedge shaped piece 77 enters into the square aper-
ture 78 formed by a groove in each gripper, these ends of the grippers are
separated. and the opposite, and the covered ends are pressed against the tube
and thus retain the paper-tube slid over it. When the piece 77 returns, the
paper-tube is released by the grippers. The piece 77 and grippers 17 derive
their motion from the cam 16 on the main shaft 4 by means of the arm 79
attached to the piece 77 and rigidly connected to the shaft 82 which is journalled
in the boxes 80 and 81. This shaft is provided at its other end with another
arm 83 actuated by the lever 84 rotatably mounted on the shaft 85 and pro-
vided at the other end with a roller 86 sliding on the cam 16. The end of the
lever 84 is always kept pressed against the cam by means of spiral spring.
The machine operates as follows:
The trough formed by the belts 27, 36 and 37 is filled with tobacco. By the
motion of the belts the string of tobacco is fed forward while resting on the
belt 27 and finally enters between the edges of the knives 49 and 50 in front of
the slide 12. The moment the motion of the belts ceases, the slide 12 is set in
motion the string of tobacco is cut off between the edges 49 and 50, and the
tobacco thus cut off is pushed by the slide 12 from the belt in under the slide 13.
The slides 12 and 13 now occupy the position shown in Fig. 5. When the
slide 13 subsequently commences to move downward, the piece 51 depresses
the tobacco into the aperture and by closing the latter forms the tobacco filler 53
(Fig. 3). The slide 12 remains in the position shown in Fig. 5 until the
piece 51 has passed the belt 27 when it returns to its former position. As soon
as it has reached this position, the belts again resume their motion. When the
slide 13 has reached its lowermost position, the plunger 55 is set in motion and
pushes in front of it the tobacco enclosed in the tube.
In the preceding rearward motion-of the plunger, one of the papertubes resting
in the grooves of the roller 65 has been slid over the tube 54 and it is retained
there by the grippers 17 which have been drawn together at the time when the
plunger remained stationary in its extreme position to the right. When the
tobacco has become inserted sufficiently far into the paper-tube, the grippers
release the latter which by the continued motion of the slide is moved away from
the tube 54, accompanying the roller 65 in its motion. Simultaneously with the
subsequent receding movement of the plunger the slide 13 moves upward, and
the roller 65 at the same time, before being shifted longitudinally, rotates a
quarter of a revolution, delivers the filled paper-tube and receives a fresh empty
tube. The same series of operations is repeated in each revolution of the shaft 4.
Having now particularly described and ascertained the nature of this said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
1. In a machine for filling empty paper-tubes of cigarettes with tobacco, an
endless belt arranged so as to carry a string of tobacco and feed forward the same
periodically in the longitudinal direction of the same, the cross-section of said
string corresponding to the cross-section of the cigarettes, a slide moveable on

page_text: or above the upper surface of said belt at right angles to the longitudinal direction
