PROVISIONAL SPECIFICATION.
Machine for Rolling Paper Mouth-pieces and Inserting them in the
Tubes of Cigarettes.
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 to be as
follows:-
The present invention relates to an entirely automatic machine for rolling paper
mouth-pieces and inserting them in the tubes of cigarettes, the machine being
especially adapted for use when the tobacco has been previously introduced in
the tubes, though it may be used to advantage also for empty tubes. In the
construction of this machine the object of the inventor has been to produce an
apparatus which, besides having a considerable productive capacity, delivers a
product of superior quality. The construction and manner of operation of the
machine are as follows:
The bevelled end of a strip of paper of a width equal to the length of the
mouth-piece to be formed is caused to pass freely in between two pieces having a
semi-cylindrical cavity and being at the time removed from each other, these
pieces subsequently closing together each side of the end of the paper-strip and hold-
ing it in a certain fixed position; a split spindle thereupon advancing grips in its slit
the piece of paper for the mouth-piece and on being set rotating winds said strip
of paper around it. The roll of paper thus formed is afterwards inserted, in
its tightly rolled condition, to the extent of about three-eight of an inch of its
length into the empty end of a cigarette-tube filled with tobacco and, as the
spindle subsequently recedes and the pieces above mentioned move away from
each other, it is allowed to expand in the tube where there is no intervening ob-
struction so that the said roll of paper fills up the tube closely. A ring of an
internal diameter equal to the diameter of the cigarette surrounds the other end
of the mouth-piece and prevents undue expansion of the end of the latter that
projects beyond the paper-tube. The cigarette is subsequently clasped, at the
point where the partly inserted mouth-piece is situated, by the jaws of a pair
of grippers which jaws are covered with mucilage and serve to hold the cigarette
stationary while the mouth-piece is being fully inserted into it. Owing to the
above-mentioned fact that the end of the mouth-piece has been previously caused
to fit closely in the tube, all particles of tobacco in the latter will be pushed in
front of the mouth-piece when being inserted and thus prevented from entering
between the latter and the tube. The path of the strip of paper forms a slightly
oblique angle to the direction of the spindle and the latter while rotating is caused
to recede at a velocity conforming to the deviation of the angle from a right
angle. Consequently, the inner coils of the mouthpiece roll will be made to
protrude slightly beyond the outer coil, and an absolutely smooth end of
the cigarette in process of forming is the result since the inner coils, owing to the
smaller resistance opposing their insertion, will after said insertion occupy the

page_text: same level as the outer one. For transporting the cigarette-tubes from a holder
to the point of the machine where the above operation is carried out and after
its completion to another receptacle, the machine is provided with an arrange
ment consisting of a box having a bottom of V-shaped section into which the
tubes are at first passed from the former holder and from which they are carried
up to an inclined plane, situated above the box, by means of a prismatic piece
movable up and down through the bottom of the box at the lowest point of the
latter, said piece having the same width as the box and a thickness corresponding
to one or a few of the cigarettes and being provided at its upper end with a
suitable arrangement for receiving a few cigarettes when the said piece is in
the lowest position and again discharging them in its highest position. On
being carried up on the inclined plane mentioned the cigarettes roll down said
plane toward a cylinder located at the bottom edge of the plane and having an
intermittent rotation and a reciprocating motion in the direction of its axis, the
cigarettes being successively received in longitudinal grooves at the surface of
said cylinder which by virtue of its reciprocating motion, transports the tubes
to the working-place and back and when subsequently rotated delivers the
ready tubes or completed cigarettes to an inclined plane below, along which they
roll into the second receptacle mentioned.
The accompanying drawings illustrate one constructive form of the machine.
Fig. 1 represents a top-view of the machine.
Fig. 2 represents a front-elevation of the same,
Fig. 3 represents a section of the machine, on line a-b, looking to the left,
Fig. 4 one on line cd looking to the right,
Fig. 5 the fly-wheel 16, and
Fig. 6-18 represent some important details of the machine.
All the parts of the machine are mounted on a supporting base-plate 1. The
shaft 14, which is the main- or driving-shaft, runs in the bearings 71 and 72 and
is revolved either by means of a belt-pulley attached to its prolongation or by
hand by means of a handle 29 fixed to the flywheel 15. The paper for forming
the mouth-pieces is present in a continuous roll carried by a cylinder (not visible
in the drawing) and is conducted between the rollers 6 and 7. Both of these
rollers are journalled in the piece 88. The strip of paper is fed forward inter-
mittently by the rotation of roller 6, effected by the toothed rack 27 which is
moved to and fro once in each revolution of the mainshaft 14 by means of the
cam 26 on shaft 14, on which cam the stud 87 slides, and the spiral spring 46,
the said rack in receding engaging with the gear 28 on the shaft of roller 6.
The piece 88 also carries the cutting-arrangement 8 which consists of two pairs
of cutters or shears 9, 10 and 11, 12. The pair 11, 12 cuts off the paper strip at
right angles to its path while 9 and 10 cuts it at an angle of about 450 or at a more
acute angle. The triangular wastepiece thus produced drops through a passage
(not shows in the drawing) underneath the machine. The cutters 10 and 12 are
secured to the piece 88, 9 and 11 on the other hand to the piece 8 which is
movable about the shaft 104 and on the other side of said shaft forms the arm 108.
The cutting operation is performed by revolving the piece 8 somewhat about
shaft 104. The piece 8 obtains the required motion from the main shaft 14 by
the action of the arm 108, and the cam 24, the lever 25, which is carried by the
support 106, and can turn about the shaft 105.
The pieces 54 and 55, which are hollowed out semicylindrically (and together
with the plunger 13, spindle 64, and other parts are illustrated in Fig. 7 viewed
from above, the upper one being removed, in Fig. 8 in a section and in
Figs. 6, 9, 10, 12, in front elevations and in details in Figs. 14-18), are secured
to the rods 48 and 49, which are of triangular section and can move up and down
in bearings 135 and 136 attached to the piece 52, and move intermittently toward
and close to each other and again' away from each other. This motion is produced
by rotating the main shaft 14 and the cam 42 upon it, the lever 44 one end of
זיז
ז'

page_text: which bears on the cam by means of the roller 43, and the connecting piece 46,
which oscillates about the shaft 45 and the forked ends of which embrace
pins 50, 51 attached to the rods 48 and. 49. The pin 51 attached to rod 49 is
prolonged beyond the connecting piece 46 and is embraced also by the forked
end of the lever 44 so that an oscillation communicated from the cam 42 to
lever 44 is transmitted to lever 49, causing it to slide upward, and by means
of the connecting piece 46 to the rod 48 which will consequently slide downward
The pieces 54 and 55 are thus caused to move away from each other. The rods
and consequently the pieces 54 and 55 are returned to their original positions
by the spiral spring 53.
The
The function of the plunger 13, which is journalled at 75 and 86, is to roll
up the paper strip into the cylinder which is to form the mouth-piece. For this
purpose it is provided with the spindle 64 the end of which is provided a slit 65.
The plunger has an intermittent rotating and reciprocating motion. It is
rotated by means of the gears 18 and 19, the shaft 17 and the cylinder 16 at
the end of the latter, said cylinder, which is coated with mucilage, being rotated
by friction with the edge of the fly-wheel 15 when the raised places e-f and gh
pass it, but remaining stationary while the sections f-g and he pass.
gear 19 is secured to the sleeve 47 in which the shaft 13 can be shifted
longitudinally while not being free to rotate in it. The sleeve 47 is journalled
in box 75. The plunger 13 is reciprocated by means of the involute cam 23 and
the lever 82, the latter being provided at one end with a stud 80 engaging with
a groove in cam 23 while the other is made in the shape of a fork embracing
the sleeve 22 which can revolve on shaft 13 but not be shifted along said shaft.
On the end of shaft.17, outside of the cylinder 16, is secured a wing 17' which
when passed by the piece 76 on the fly-wheel 15 is given by this piece a position.
parallel to the periphery of the fly-wheel, so that the shaft 17, plunger 13, and
spindle 64. always occupy a certain position when the piece 76 has just passei
the wing. 17, said position being characterized by a horizontal position of the
slit 65 of spindle 64. This is necessary in order that the slit 65 when the spindle
is subsequently advanced. shall receive in it the paper held between the pieces 54
and 55.
In each of the pieces .54 and 55 there is a longitudinally-movable piece 66
and 67 consisting of a pin at one end of which is fixed a plate & while at the other
there is, secured one.half, 4, of a tube 110 which is cut off obliquely and divided
in two halves by a plane passing through the point thus formed and its axis.
(See Figs. 6-11 and 15-18). The spiral springs 68, 69 strive to shift the pieces 66
and 67, toward the left hand side and to thus retain them in the position shown
in Figs.. 6 and, 9. When the plunger 13 is advanced subsequent to the closing
together, of the pieces 54 and 55 (Fig. 9), its end striking the plates moves
the pieces 66, 67 forward, causing the halves of the tube to be pushed out of
the pieces 54.55 so as to form in the continuation of the latter the tube 110.
which is obliquely cut off at thie, end (Fig. 10 and 11). In the return motion
of the plunger the pieces 66 and 67 are restored to their original positions, and
as a result the same are withdrawn within the pieces 54 and 55. As will be
explained below, the tube 110 serves to facilitate the introduction of the end
of the rolled-up paper-mouthpiece in the paper-tube. The upper half of the
tube is provided at the edge 111 with a recess so as not to form any obstruction
in winding the paper for the mouth-piece on to the spindle 64. For the same
reason one side of the piece 54 is made longer than the other (see Figs. 8 and 9).
For pushing the roll of mouth-piece paper into the paper tube the machine
is provided with a rod 56 of triangular section which can be shifted in the bear-
ings. 74 and 60 and carries the piece 59 to which is secured a circular disc 57 of
the same external diameter as the mouth-piece to be formed, and which disc is
perforated at the middle so as to admit of the spindle 64 passing through.
Moreover, the two upwardly-extending arms 107 and 109 of the piece 59 serve

page_text: as bearings for the pin 61 which can slide longitudinally in said piece 59 and
to which is attached an arm 70 terminating in a hub 112 surrounding the disc 57.
This hub has two slots, viz., 114 providing room for the arm 70 supporting the
disc 57 and 113 preventing the hub from obstructing the path of the paper-strip
in winding on to spindle 64. The spiral spring 62 strives to retain the hub 112
in and return it to the position shown in Figs. 6-10. The object of hub 112
is to prevent undue expansion of the mouth-piece roll after the parting of
pieces 54 and 55. The rod 56 derives its motion from the main shaft by means
of the involute cam 23 with the groove 78' of which the stud 77 of the lever 21
engages. The lever 21 is pivoted on the stud 22¹ and its other, forked end
embraces the pin 84 attached to the rod 56.
To hold the tube of the cigarette in place during the insertion of the mouth-
piece the machine is provided with a clamping-arrangement in the shape of a pair
of grippers the jaws 89 and 90 of which are coated with mucilage and during
the said insertion clasp the cigarette and hold it fast owing to the friction of the
thin paper of the tube on the mucilage of the grippers being greater than
that at the surface of contact of the mouth-piece and the tube. The grippers
derive their motion from the main-shaft by means of the cam 30, lever 33, and
rod 32 to which the wedge-shaped piece 35 is secured. The lever 33, which is pro-
vided with a roller 31 sliding on the cam 30, is thus given a rocking motion and
the rod 32 a sliding motion which causes the piece 35 to be forced in between
the ends of the grippers so as to separate them and cause the opposite ends to
approach to each other. By means of the spiral springs 115 and 95 the grippers
are kept open while the lower section of the periphery of cam 30 passes the sliding
roller 31.
The principal parts of the arrangement for transporting the tubes to and fro,
which arrangement is shown in Figs. 19-23 are the box or holder 116, the bottom
of which slopes on each side toward the aperture 132, and the vertically-movable
piece 125. The holder 117, which contains the tubes to be provided with mouth-
pieces, closely adjoins the box 116, and its wall 118 which adjoins the latter can
be removed so as to successively admit the tubes from the former holder to the
latter. One or more tubes, when the piece 125 occupies its lowest position,
drop into the space 130 (Fig. 22) formed by the said piece 125 and the knee-shaped
piece 129. When the piece 125 is subsequently elevated by the lever 131 which
with its forked end embraces the pin 126 the tubes resting in the space 130
accompany it in its upward motion. As soon as the lip 133 strikes the pro-
jection 134, the upward motion of piece 125 ceases, whereas the rod 128 and
piece 129 continue to be moved upward. while the spiral spring 127 is compressed,
until they have assumed the position shown in Fig. 20. The tubes contained in
the space 130 then roll down the inclined plane 119 toward the cylinder 2
(Fig. 15). If a greater number of tubes than can find room on the plane 119
are brought up, the excess is returned to the holder 116 when the piece 125
descends.
In each revolution of the shaft 14 the cylinder 2 is rotated a quarter of a turn,
and afterward it slides to and fro along the shaft 101.
When the cylinder 2 is rotated the lowest situated tube on plane 119 drops into
its groove 3 which is subsequently made to face upwards, and the cigarette now
accompanies the cylinder in its longitudinal motion and is slid over the tube 110
as the cylinder is shifted toward the latter. In this operation the tube is retained
in place in the groove only by the arm 5 resting lightly on the top of it, said
arm being fulcrumed on the tapp 124 and provided with a contact-piece of rubber.
As soon as the end of the paper-tube which adjoins the tube 110 strikes the
pieces 54 and 55. the arm 5, the pressure of which can be regulated by shifting
the weight 122, begins to slide over the paper tube and continues to do so as long
as the movement of the cylinder in the direction of the tube 110 is going on.
This arrangement is necessary and cannot be replaced by a terminating plane

page_text: limiting the length of the grooves owing to the fact that when the machine is at
work the tubes are filled with tobacco which may be projecting more or less be-
yond the end of the papertube that points away from the tube 110. The end
of the paper tube would therefore be liable to crush against the pieces 54 and 55
when being slid over the tube 110.
The shaft 101, and consequently the cylinder 2, obtain their motion in the
manner that in each revolution of the shaft 14 the hook 40, which is given a
reciprocating motion by the cam 39 and spiral spring 134, engages with a pin-
wheel secured to the shaft 101 and formed of four pins 41. The cylinder 2 com-
municates its reciprocating motion to the lever 38 which is pivoted on the tap 96
and has a forked end which embraces the sleeve 98 while its other end is
provided with a stud 102 engaging with the groove of the involute cam 37. The
feeding piece 125 obtains motion by means of ordinary gearing from the shaft 14
in such a manner that the piece 125 moves up and down once in each two revolu-
tions of the shaft 14.
The operation of the machine is as follows:
The strip of paper being advanced by the roller passes beneath the piece 8 and
cutters 10 and 12 in between the parted pieces.54 and 55 until its end projects
slightly beyond the latter (as shown in Fig. 7). The movement of the strip of
paper now ceases. The pieces 54 and 55 subsequently close together and in so
doing clasp the strip of paper between them (Fig. 9). Plunger 13, which at this
moment does not rotate and by the piece 17' has been given the position in which
the slit 65 is horizontal, is now advanced so that the paper enters the slit 65, and
the tube 110, as described above, passes out of the pieces 54 and 55. (Figs. 10
and 11.) The plunger 13 is now rotated and winds on the paper for the mouth-
piece. When the proper length has been wound on, the rotation of the plunger
is arrested for a moment in which the shears are brought into action to cut off
the strip of paper. When this operation has been performed, the rotating move-
ment of the plunger is continued an instant until the whole band of paper cut
off is wound on. The mouth-piece roll now occupies a position in relation to
the spindle 64. hub 112, disc 57, pieces 54 and 55, and tube 110, as shown in
Fig. 10, or such a position that one of its ends is surrounded by the hub 112 and
the other by the tube 110. Meantime a paper-tube has been fed forward by the
cylinder 2 (between the grippers 89 and 90) and pushed over the tube 110 so far
as permitted by the pieces 54 and 55 (Figs. 10 and 12). The rod 56 is now set
in motion and by means of the disc 57 pushes the mouth-piece roll forward
through the tube 110. The said movement of rod 56 ceases when the farther
end of the paper roll has reached or passed slightly beyond the plane of the
extreme end of the grippers 89 and 90. The plunger 13 now recedes together
with the spindle 64 and the pieces 66 and 67. and the points simultaneously
withdraw inside the pieces 54 and 55. The said pieces, 54 and 55, subsequently
part from each other and the mouth-piece consequently unrolls as much as per-
mitted by the paper-tube and hub 112 which now surround its ends, the mouth-
piece being thus made to close up tight to the paper-tube. The grippers 89 and 90
now approach to each other until they embrace and slightly press on the paper-
tube. Fig. 12 shows the relative positions of the various parts in this moment.
The rod 56 now again commences to move, pushing the entire mouth-piece into
the paper-tube. In order, however, that the hub 112 shall not form an obstruc-
tion in this operation and the paper-tube be crushed by its edge, its motion in
the direction of the paper-tube must be discontinued before it touches the latter.
This is accomplished by the pin 61 striking the spring 63 at a suitable moment,
the spiral spring 62 being consequently compressed and the motion of the hub 112
ceasing until the disc 57. has arrived on a plane with the end of the hub 112:
from this moment on, the latter, owing to the arm 70 striking against the end
of the slot 114, again accompanies the disc 57 and rod 56 while the spring 63
yields to the pressure (Fig. 13). The motion of the rod 56 and disc 57 is adjusted

page_text: so as to continue until the mouth-piece has become fully inserted in the tube.
This adjustment is effected by the regulating screw 58.

Machine for Rolling Paper Mouth-pieces and Inserting them in the
Tubes of Cigarettes.
We, GUSTAF ADOLF HAGELBERG, of Eriksgatan 7, Helsingfors, Finland, Notary
to the Supreme Court, and LEONARD LINDELOF, of Konstantinsgatan 25, Helsing-
fors, 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 ascer-
tained in and by the following statement:-
-
The present invention relates to an entirely automatic machine for rolling paper
mouth-pieces and inserting them in the tubes of cigarettes, the machine being
especially adapted for use when the tobacco has been previously introduced in
the tubes, though it may be used to advantage also for empty tubes.' In the
construction of this machine the object of the inventor has been to produce an
apparatus which, besides having a considerable productive capacity, delivers a
product of superior quality. The construction and manner of operation of, the
machine are, briefly, as follows:
The bevelled end of a strip of paper of a width equal to the length of the
mouth-piece to be formed is caused to pass freely in between two pieces having a
semi-cylindrical cavity and being at the time removed from each other, these pieces
subsequently closing together each side of the end of the paper-strip and holding
it in a certain fixed position; a split spindle thereupon advancing grips in its slit
the piece of paper for the mouth-piece and on being set rotating winds said strip
of paper around itself. The roll of paper thus formed is afterwards inserted, in
its tightly rolled condition, to the extent of about three-eight of an inch of its
length into the empty end of a cigarette-tube filled with tobacco and, as the
spindle subsequently recedes and the pieces above mentioned move away from
each other, it is allowed to expand in the tube where there is no intervening ob-
struction so that the said roll of paper fills up the tube closely. A ring of an
internal diameter equal to the diameter of the cigarette surrounds the other end
of the mouth-piece and prevents undue expansion of the end of the latter that
projects beyond the paper-tube. The cigarette is subsequently clasped, at the
point where the partly inserted mouth-piece is situated, by the jaws of a pair
of grippers which jaws are covered with rubber and serve to hold the cigarette,
stationary while the mouth-piece is being fully inserted into it. Owing to the
above-mentioned fact that the end of the mouth-piece has been previously caused
to fit closely in the tube, all particles of tobacco in the latter will be pushed in
front of the mouth-piece when being inserted and thus, prevented from entering
between the latter and the tube. The path of the strip of paper forms a slightly
oblique angle to the direction of the spindle and, the latter while rotating is caused
to recede at a velocity conforming to the deviation of the angle from a right
angle. Consequently, the inner coils of the mouth-piece roll will be made to
protrude slightly, beyond the outer coil, and an absolutely smooth end of the
cigarette in process of forming is the result since the inner coils, owing to
the smaller resistance opposing their insertion, will after said insertion occupy the

page_text: same level as the outer one. For transporting the cigarette-tubes from a holder
to the point of the machine where the above operation is carried out and after
its completion to another receptacle, the machine is provided with an arrange-
ment consisting of a box having a bottom of V-shaped section into which the
tubes are at first passed from the former holder and from which they are carried
up to an inclined plane, situated above the box, by means of a prismatic part
movable up and down through the bottom of the box at the lowest point of the
latter, said part having the same width as the box and a thickness corresponding
to one or a few of the cigarettes and being provided at its upper end with a
suitable arrangement for receiving a few cigarettes when the said part is in
the lowest position and again discharging them in its highest position. On
being carried up on the inclined plane mentioned the cigarettes roll down.said
plane toward a cylinder located at the bottom edge of the plane and having an
intermittent rotation and a reciprocating motion in the direction of its axis, the
cigarettes being successively received in longitudinal grooves at the surface of
said cylinder which by virtue of its reciprocating motion, transports the tubes
to the working-place and back and when subsequently rotated delivers the
ready tubes-or completed cigarettes to an inclined plane below, along which they
roll into the second receptacle mentioned.

Fig. 5 the fly-wheel 16, and
Fig. 6 to 23 represent some important details of the machine.
Drawings Figs. 24-25 left with this specification illustrate further details.
The parts of the machine are mounted on a supporting base-plate 1. The
shaft 14, which is the main- or driving-shaft, runs in the bearings 71 and 72 and
is revolved either by means of a belt-pulley attached to its prolongation or by
hand by means of a handle 29 fixed to a flywheel 15. The paper for forming
the mouth-piece is present in a continuous roll carried by a cylinder (not shown
in the drawing) and is conducted between the rollers 6 and 7. Both of these
rollers are journalled in the support 88. The strip of paper is fed forward inter-
mittently by the rotation of the roller 6, effected by the toothed rack 27 which is
moved to and fro once in each revolution of the mainshaft 14 by means of the
cam 26 on shaft 14, on which cam the stud 87 slides, and the spiral spring 46,
the said rack in receding engaging with the pinion 28 on the shaft of the roller G.
The support 88 also carries the cutting-arrangement 8 which consists of two pairs
of cutters or shears 9, 10, and 11, 12. The pair 11, 12 cuts off the paper strip at
right angles to its path while 9 and 10 cuts it at an angle of about 45° or at a more
acute angle. The triangular wastepiece thus produced drops through a passage
(not shown in the drawing) underneath the machine. The cutters 10 and 12 are
secured to the support 88, 9 and 11 on the other hand to the part 8 which is
movable about the shaft 104 and on the other side of said shaft forms the
arm 108. The cutting operation is performed by oscillating the piece 8 about
shaft 104. The piece S obtains the required motion from the main shaft 14 by
the action of the arm 10S, and the cam 24, the lever 25, which is carried by the
support 108, and can turn about the shaft 105.
The pieces 54 and 55, which are hollowed out semicylindrically (and together
with the plunger 13, spindle 64, and other parts are illustrated in Fig. 7 viewed
from above, the upper one being removed, in Fig. 8 in a section and in
Figs. 6, 9, 10, 12, in front-elevations and in details in Figs. 14-18), are secured
o the rods 48 and 49, which are of triangular section and can move up and down
n bearings 135 and 136 attached to the support 52, and move intermittently toward
and close to each other and again away from each other. This motion produced

page_text: by rotating the main shaft 14 and the cam 42 upon it, the lever 44 one end of
which bears on the cam by means of the roller 43, and the connecting piece 46,
which oscillates about the shaft 45 and the forked ends of which embrace
pins 50, 51 attached to the rods 48 and 49. The pin 51 attached to rod 49 is
prolonged beyond the connecting piece 46 and is embraced also by the forked
end of the lever 44 so that an oscillation communicated from the cam 42 to
lever 44 is transmitted to lever 49, causing it to slide upward, and by means
of the connecting piece 46 to the rod 48 which will consequently slide downward.
The pieces 54 and 55 are thus caused to move away from each other. The rods
and consequently the pieces 54 and 55 are returned to their original positions
by the spiral springs 53.
The function of the plunger 13, which is journalled at 75 and 86, is to roll
up the paper strip into the cylinder which is to form the mouth-piece. For this
purpose it is provided with the spindle 64 at the end of which is provided a slit 65.
The plunger has an intermittent rotating and reciprocating motion. It is rotated
by means of the gear-wheels 18 and 19, the shaft 17 and the cylinder 16 at
the end of the latter, said cylinder, which is coated with rubber, being rotated
by friction of the edge of the fly-wheel 15 when the raised places e-f and g―h
pass it but remaining stationary while the sections f-g and he pass. The
gearwheel 19 is secured to the sleeve 47 in which the shaft 13 can be shifted
longitudinally while not being free to rotate in it. The sleeve 47 is journalled
in the box 75. The plunger 13 is reciprocated by means of the involute cam 23 and
the lever 82, the latter being provided at one end with a stud 80 engaging with
a groove in cam 23 while the other is made in the shape of a fork embracing
the sleeve 22 which can revolve on shaft 13 but not be shifted along said shaft.
On the end of shaft 17, outside of the friction-pinion 16, is secured a wing 17' which
when passed by the piece 76 on the fly-wheel 15 is given by this piece a position
parallel to the periphery of the fly-wheel, so that the shaft 17, plunger 13, and
spindle 64 always occupy a certain position when the piece 76 has just passed
the wing 17, said position being characterized by a horizontal position of the
slit 65 of spindle 64. This is necessary in order that the slit 65 when the spindle
is subsequently advanced shall receive in it the paper held between the piece 54
and 55.
In each of the pieces 54 and 55 there is a longitudinally-movable piece 66
and 67 consisting of a pin at one end of which is fixed a washer k while at the other
there is secured one half, 1, of a tube 110 which is cut off obliquely and divided
in two halves by a plane passing through the point thus formed and its axis.
(See Figs. 6-11 and 15-18). The spiral spring 68, 69 strive to shift the pieces 66
and 67 toward the left hand side and to thus retain them in the position shown
in Figs. 6 and 9. When the plunger 13 is advanced subsequent to the closing
together of the pieces 54 and 55 (Fig. 9), its end striking the plates moves
the pieces 66, 67 forward, causing the halves of the tube to be pushed out of
the pieces 54, 55 so as to form in the continuation of the latter the tube 110
which is obliquely cut off at the end. (Fig. 10 and 11). In the return motion
of the plunger the pieces 66 and 67 are restored to their original positions, and
as a result the tube 110 is withdrawn within the pieces 54 and 55. As will be
explained below, the tube 110 serves to facilitate the introduction of the end
of the rolled-up paper-mouthpiece in the paper-tube. The upper half of the
tube is provided at the edge 111 with a recess so as not to form any obstruction
in winding the paper for the mouth-piece on to the spindle 64. For the same
reason one side of the piece 54 is made longer than the other (see Figs. 8 and 9).
For pushing the roll of mouth-piece paper into the paper tube the machine
is provided with a rod 56 of triangular section which can be shifted in the bear-
ings 74 and 60 and carries the piece 59 to which is secured a circular disc 57 of
the same external diameter as the mouth-piece to be formed, and which disc is
perforated at the middle so as to admit of the spindle 64 passing through.
Moreover, the two upwardly-extending arms 107 and 109 of the piece 59 serve

page_text: as bearings for the pin 61 which can slide longitudinally in said piece 59 and
to which is attached an arm 70 terminating in a hub 112 surrounding the disc 57.
This hub has two slots, viz., 114 providing room for the arm 70 supporting the
disc 57, and 113 preventing the hub from obstructing the path of the paper-strip
in winding on to spindle 64. The spiral spring 62 strives to retain the hub 112
in and return it to the position shown in Figs. 6-10. The object of hub 112
is to prevent undue expansion of the mouth-piece roll after the parting of
pieces 54 and 55. The rod 56 derives its motion from the main shaft by means
of the involute cam 23 with the groove 78' of which the stud 77 of the lever 211
engages. The lever 21 is pivoted on the stud 22¹ and its other, forked end
embraces the pin 84 attached to the rod 56.
To hold the tube of the cigarette in place during the insertion of the mouth-
piece the machine is provided with a clamping-arrangement in the shape of a
pair of grippers the jaws 89 and 90 of which are coated with rubber and during
the said insertion clasp the cigarette and hold it fast owing to the friction of
the thin paper of the tube against the rubber of the grippers being greater than
that at the surface of contact of the mouth-piece and the tube. The grippers
derive their motion from the main-shaft by means of the cam 30, lever 33, and
rod 32 to which the wedge-shaped piece 35 is secured. The lever 33, which is pro-
vided with a roller 31 sliding on the cam 30, is thus given a rocking motion and
the rod 32- a sliding motion which causes the piece 35 to be forced in between
the ends of the grippers so as to separate them and cause the opposite ends to
approach to each other. By means of the spiral spring 115 and 95 the grippers
are kept open while the lower section of the periphery of cam 30 passes the sliding
roller 31.
The principal parts of the arrangement for transporting the tubes to and fro,
which arrangement is shown in Figs. 19-23 are the box or holder 116, the bottom
of which slopes on each side toward the aperture 132, and the vertically-movable
part 125. The holder 117, which contains the tubes to be provided with mouth-
pieces, closely adjoins the box 116, and the separating wall 118 between the boxes
can be removed so as to successively admit the tubes from the former holder
to the latter. One or more tubes, when the piece 125 occupies its lowest position,
drop into the space 130 (Fig. 22) formed by the said piece 125 and the knee-shaped
piece 129. When the piece 125 is subsequently elevated by the lever 131 which
with its forked end embraces the pin 126 the tubes resting in the space 130
accompany it in its upward motion. As soon as the lip 133 strikes the pro-
jection 134, the upward motion of piece 125 ceases, whereas the rod 128 and.
piece 129 continue to be moved upward, while the spiral spring 127 is compressed,
until they have assumed the position shown in Fig. 20. The tubes contained
in the space 130 thereupon roll down the inclined plane 119 toward the cylinder 2
(Fig. 20). If a greater number of tubes than can find room on the plane 119
are brought up, the excess is returned to the holder 116 when the piece 125
descends.
In each revolution of the shaft 14 the cylinder 2 is rotated a quarter of a turn.
and afterward it slides to and fro along the shaft 101.
When the cylinder 2 is rotated the lowest situated tube on plane 119 drops into-
its groove 3 which is subsequently made to face upwards, and the cigarette now.
accompanies the cylinder in its longitudinal motion and is slid over the tube 110
as the cylinder is shifted toward the latter. In this operation the tube is retained
in place in the groove only by the arm 5 resting lightly on the top of it, said
arm being fulcrumed on the pin 124 and provided with a contact-piece of rubber.
As soon as the end of the paper-tube which adjoins the tube 110 strikes the
pieces 54 and 55, the arm 5, the pressure of which can be regulated by shifting
the weight 122, begins to slide over the paper tube and continues to do so as long
as the movement of the cylinder in the direction of the tube 110 is going on.
This arrangement is necessary and cannot be replaced by a terminating plane
limiting the length of the grooves owing to the fact that when the machine is at

page_text: work the tubes are filled with tobacco which may be projecting more or less
beyond the end of the paper tube that points away from the tube 110. The end
of the paper tube would therefore be liable to crush against the pieces 54 and 55
when being slid over the tube 110.
The shaft 101, and consequently the cylinder 2, obtain their motion in the
manner that in each revolution of the shaft 14 the rod 40, which is given a
reciprocating motion by the cam 39 which acts upon the lug 199 (Fig. 24) so as
to pull the rod 40 in one direction, whereupon the same is by the spring 200
pulled back, engages with a pin-wheel secured to the shaft 101 and formed of
four pins 41 in such manner that the axle 101 is turned a quarter of a revolution
for each revolution of the axle 14. The cylinder 2 communicates its reciprocating
motion to the lever 38, which is pivoted on the tap 96 and has a forked end
which embraces the sleeve 98 (Fig. 23) while its other end is provided with a
stud 102 engaging with the groove of the involute cam 37. The feeding piece 125
may be connected with and be set in motion from the shaft 14 by means of any
suitable ordinary gearing in such a manner that the piece 125 moves up and
down once in each two revolutions of the shaft 14.
The operation of the machine is as follows:
The strip of paper being advanced by the roller passes beneath the piece 8 and
cutters 10 and 12 in between the parted pieces 54 and 55 until its end projects
slightly beyond the latter (as shown in Fig.7). The movement of the strip of
paper now ceases. The pieces 54 and 55 subsequently close together and in so
doing clasp the strip of paper between them (Fig. 9). The plunger 13, which at this
moment does not rotate and by the piece 171 has been given the position in which
the slit 65 is horizontal, is now advanced so that the paper enters the slit 65, and
the tube 110, as described above, passes out of the pieces 54 and 55. (Figs. 10
and 11). The plunger 13 is now rotated and winds on the paper for the mouth-
piece. When the proper length has been wound on, the rotation of the plunger
is arrested for a moment and the shears are brought into action to cut off
the strip of paper. When this operation has been performed, the rotating move-
ment of the plunger is continued an instant until the whole band of paper cut
off is wound on. The mouth-piece roll now occupies a position in relation to
the spindle 64, hub 112, disc 57, pieces 54 and 55, and tube 110, as shown in
Fig. 10, or such a position that one of its ends is surrounded by the hub 112 and
the other by the tube 110. Meanwhile a papertube has been fed forward by the
cylinder 2 (between the grippers 89 and 90) and pushed over the tube 110 so far
as permitted by the pieces 54 and 55 (Figs. 10 and 12). The rod 56 is now set
in motion and by means of the disc 57 pushes the mouth-piece roll forward
through the tube 110. The said movement of rod 56 ceases when the farther
end of the paper roll has reached or passed slightly beyond the plane of the
extreme end of the grippers 89 and 90. The plunger 13 now recedes together
with the spindle 64 and the pieces 66 and 67, and the points / simultaneously
withdraw inside the pieces 54 and 55. The said pieces, 54 and 55, subsequently
part from each other and the mouth-piece consequently unrolls as much as per-
mitted by the paper-tube and hub 112 which now surrounds its ends, the mouth-
piece being thus made to close up tight to the paper-tube. The grippers 89 and 90
now approach to each other until they embrace and slightly press on the paper-
tube, Fig 12 shows the relative positions of the various parts in this moment.
The rod 56 now again commences to move, pushing the entire mouth-piece into
the paper-tube. In order, however, that the hub 112 shall not form an obstruc-
tion in this operation and the paper-tube be crushed by its edge, its motion in
the direction of the paper-tube must be discontinued before it touches the latter.
This is accomplished by the pin 61 striking the spring 63 at a suitable moment,
the spiral spring 62 being consequently compressed and the motion of the hub 112
ceasing until the disc 57 has arrived on a plane with the end of the hub 112;
from this moment on, the latter, owing to the arm 70 striking against the end
of the slot 114, again accompanies the disc 57 and rod 56 while the spring 63

page_text: yields to the pressure (Fig. 13). The motion of the rod 56 and disc 57 is adjusted
so as to continue until the mouth-piece has become fully inserted in the tube
This adjustment is effected by the regulating screw 58.
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. A machine for rolling paper mouthpieces and inserting them in the tubes
of cigarettes, in which the paper-strip for forming the mouth-piece is fed forward
by a roller and made to enter freely between two parted pieces (54 and 55) each
provided with a semicylindrical cavity, whereupon the said pieces are caused
to close together and hold between them the aforesaid strip of paper, which is
grasped by a previously-advanced split-spindle (64) and wound on to said spindle
and partly inserted into the paper-tube in front of the spindle by means of a
disc (57) surrounding the spindle and connected to a reciprocating rod parallel
to the latter, the spindle being afterwards withdrawn and the semicylindrically
recessed pieces separated from each other so as to release the mouthpiece which
consequently expands and while closing up tightly to the internal walls of the
paper-tube is fully inserted by means of the rod and disc (57) in the paper-tube,
which during this operation is enclosed by a pair of grippers coated with rubber.
2. In a machine as characterized in claim 1 the arrangement of a tube (110)

closing together of the semicylindrically-recessed pieces (54 and 55) is pushed out
off the latter and, when the paper-tube has been slid over it and the mouth-
piece been partly inserted in the paper-tube, is again with-drawn into the
aforesaid pieces (54 and 55) previous to the parting of said pieces.
3. In a machine as characterized in claim 1, the arrangement that the extreme
end of the mouth-piece while being inserted into the paper-tube is surrounded
