page_text: A communication from ALBERT STERN, of 28, Bürgerstrasse, Dresden-Pieschen,
in the Empire of Germany, Engineer.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a device for cigarette making machines to enable them
to manufacture cigarettes with mouth-pieces.
The device itself consists of several parts, namely a device for cutting off the
paper, rolling and cementing the paper-tube, a device for cutting off paper and
rolling the mouth-piece and finally of an intermediate part receiving the paper-
tube, supplying it to the tobacco-filling device and afterwards to the mouth-piece
rolling device, which connects the mouth-piece to the paper-tube already filled
with tobacco.
The paper for making the tube is fed from rolls under a slide-piece to a device
which grasps the paper after a length required for one cigarette has been cut off,
after the plate in its descent has pressed the edge of the paper against a roller
provided with gum or cohesive material, brings the paper-sheet to a shaft provided
with recesses, by the rotation of which shaft,--the holder being also pressed against
it-the paper-tube is formed and the edge, provided with adhesive material
pressed down.
The shaft is then advanced laterally in order to bring the paper-tube into a
clamping or holding device, the jaws of which close and remove the tube from
the shaft, when the latter moves back. The clamping device then also makes a
lateral movement, and comes into position against a tube, through which tobacco
is introduced into the paper-tube, by means of a plunger, said plunger pushing
the tobacco into the paper-tube so far as to leave at the back a free space for
introducing the mouth piece. After the plunger has been withdrawn, the clamp-
ing-device with the filled paper-tube first returns into its original position and
then travels towards the mouth-piece device, by a lateral movement.
The apparatus for rolling up the mouth-piece-which is made of a continuous
piece of paper-consists of a guide through which the paper is fed to a cutter
placed in an inclined position, which cuts off obliquely from the paper band a
correspondingly long piece, which is brought on a mandrel; the rotation of which
effects the rolling up of the paper. The paper thus rolled up is stripped off or
removed from the mandrel say by means of a ring, and introduced into the
cigarette. During its return motion the clamping device opens, and the finished
cigarette is ejected; the same series of operations then re-commencing.
This invention thus consists of apparatus for manufacturing cigarettes with
mouth-pieces, characterized by the arrangement of a clamping- or holding device

page_text: To enable the working of the machine and the co-operation of its parts to be
better understood, it is best to divide the description of the whole working into
three parts, rolling up the paper-tube, transporting it to the tobacco filling device
which latter forms no part of this invention, and therefore will not be described,
and finally the rolling up of the mouth pieces, the parts effecting these operations
being at the same time fully described.
Rolling up the Paper Tube.--The manufacture of paper tubes from tissue paper
or the like is effected by unrolling paper from a supply roll and passing it through
a guide to the cutter which cuts off the desired lengths. A clamping device then
carries the sheet of paper cut off to a roller which applies a narrow strip of gum
or adhesive material to one edge of the paper, whereupon the rolling-up mandrel
seizes the paper and rolls it into a tube, the gummed edge being strongly com-
pressed by a special device. By a lateral movement of the mandrel, the finished
tube is brought outwards in order to be removed, by a suitable device from the
returning mandrel.
The intermittent feeding of the paper from the suppily roll is effected by
rollers 1 and 2 (Figs. 1 and 2) which frictionally engage with a pulley 3 the broad
rim of which has a layer of rubber felt or similar surface. The movement of the
pulley 3 for feeding the paper is, according to the example illustrated, effected
by a rod 4 connected at one end to the edge of a sprocket wheel 5 and adjustably
mounted at the other end in a slot of a lever 6 loose on the shaft 7 of the friction
pulley 3. To this shaft is keyed a pulley 8 having a grooved rim, which
co-operates with a brake-block 9 mounted on the frame by means of a spring, for
preventing a backward rotation of the friction pulley 3. The lever 6 carries in
its forked end 6" a friction pawl 6b pivotted at 6, and acted upon by a spring 6d,
wherely at each movement of the rod 4 and lever 6 in the direction of the arrow,
the pulley 8 & consequently the roller 3 will be partially rotated. This inter-
mittent motion communicated to the latter by the rod 4 effects an intermittent
advance of the paper, the extent of said advance being capable of being varied
by adjusting the rod 4 in the slot of the lever 6, according as it is desired to make
shorter or longer paper tubes.
The paper passes first through a guide consisting of two plates 10 connected
together with a small interval between them, and then (Fig. 3) after a length
has been cut off by a pivoted cutter 13 oporated by a rod 14 from a toothed
segment 15, the strip is seized by a clamping device consisting of a block 11 (Fig. 1)
with a bracket 12 placed over it and sliding in guides.
On the bracket there is a sliding roller 16 resting on a pivoted plate 17. To
open and close the clamping device said plate is raised and lowered by pivoted
levers 18 18, 18 acted upon by a cam 19 mounted on the driving shaft C a roller 20
attached to the lever 18 travelling on said cam.
The closed clamping device brings the sheet of paper first to the roller which
applies the gum, and then to the rolling up mandrel. To enable it to be moved
laterally the clamping device is arranged in a guide in a fixed part 21 (Fig. 4)
connected by a link 22 to the double armed lever 24 pivoted about a pin 23 a
roller 25 on the short arm of said lever engaging with a cam dise 26 on the driving
shaft C.
On a support 28 is arranged the gum reservoir 29 having a spreading roller 30.
In order to apply the gum only in a narrow strip at the edge of the paper, there
is arranged on the gum reservoir 29 a bracket 32 pivoted about a pin 31 and
provided at the top with a thin plate 33 having a downwardly bent front edge.
At the back of this bracket projects a pin 34 (Figs. 2 and 4) under which passes
a projection 35 on the connecting rod 4 during the advance of the latter and strikes
said pin whereby the bracket 32 is caused to turn on its pivot so that the projec-
tion or plate 33 presses the paper against the gumming roller for a short time.
The movement of the clamping device 11 towards the gum reservoir 29 can be
regulated by means of a screw 36 in order to provide a more or less wide strip of
paper with gum,

page_text: This sectioning of the rod for opening and closing the jaws 79 and the connec
tion of its parts by means of a slide is necessary, as the upper part 83 must partici-
pate in the oscillations of the lever 75, while the lower part 87 is only allowed
to have a vertical movement in order to produce a sharp blow against the small
cam 90 on the shaft C. The arrangement described of the separate driving parts
of the transport device on the main driving shaft is such that in the position of
rest the tongs are near the paper tube making device with the jaws open, the
finished tube being seized by the jaws closing upon it and drawn off the mandrel
and brought to the groove of the tobacco rolling apparatus by a lateral movement
of the whole device, where it is filled with tobacco and carried by the return move-
ment of the transport device to the mouth piece rolling apparatus, in order finally
to insert the mouth piece and to release the finished cigarette by opening the jaws
which then return into their original position.
Forming the Paper Mouth-Pieces. For this purpose a piece of paper of suit-
able length is cut off from a roll of paper in an oblique manner so as to obtain
a point with which the rolling begins. This is effected by a slotted former on
which moves a plate for clamping or holding the paper. The finished mouth piece
is removed from the formor by means of a ring and inserted into the filled paper
tube and held to the last by the sliding plate so that it cannot unroll before being
introduced into the paper tube.
The rolling up former 91 (Figs. 11 and 12) into the slot 92 of which the paper
is introduced by a device hereinafter described, is surrounded by a sleeve 93 having
double slots 94 (Fig. 13) and is carried in a partially hollow shaft 95, in the rota-
tion of which it is caused to participate by a pin 96 guided in a double slot 97 in
the shaft 95, thus preventing a lateral movement of the core during the movement
of the shaft in its longitudinal direction.
The shaft 95 with the former 91 is caused to rotate at a great speed from the
main driving shaft C by means of a toothed segment 98 and toothed gearing 99,
the former 91 rolling up the paper introduced into its slot 92, a spring controlled
plate 100 (Figs. 12 and 13) in contact with the former pressing the paper and
maintaining the rolled up mouth-piece in shape. The shaft 95 passes loosely
through the upper toothed wheel 99 and is connected to it by a tooth shaped
projection 102 engaging with a longitudinal groove 101 in it, so as to enable the
shaft 95 to move freely in a longitudinal direction. To stop and hold the shaft 95
stationary at a desired moment a tooth 105 (Fig. 14) engages with a recess 103
of a disc shaped projection 104 of the toothed wheel 99, said tooth 105 being
secured to a lever 106, which is intermittently raised by its roller 108 coming
in contact with an are or cam 107 of the toothed segment 98 and slides along the
disc 104 and is caused by the spring 110 to spring in into the recess 103 when it
comes opposite to it.
The longitudinal movement of the shaft 95 for removing the mouth piece from
the former 91 and inserting it into the paper tube filled with tobacco, is effected
by a double-armed lever 111 adjustable in guide-slots a friction roller 112 on the
lower end of said lever sliding on a cam 113 on the main shaft C, the upper end
of the lever 111 being connected by a ball and socket joint 114 with the shaft 95.
The latter is thus intermittently advanced and retracted, consequently the circular
front part which surrounds the former 91 (Fig. 11) removes the mouth piece
and pushes it out of the sleeve 93.
-
A very important feature of the device is the feeding and cutting off of the
paper from the main roll which is effected only when the mouthpiece has been
made, by means of two cutters 123 and 124 placed at an acute angle to each other,
in such manner that one cutter cuts off the finished mouthpiece in a straight line,
while the other cutter placed obliquely, cuts the paper obliquely for the next
mouthpiece, so that a triangular piece of paper is cut out and falls out from the
machine.
The paper is arranged in a movable guide 115 (Fig. 2) covered by a fixed
plate 116 and is caused in a suitable manner--in this case by a stop 117 on the

page_text: up mouth-pieces, comprising a slotted former surrounded by a slotted sleeve and
adjustable in a slotted shaft in combination with a spring plate for pressing on
the rolled mouthpiece.
6. In a cigarette making machine of the kind described, a movable guide 115
for advancing the paper and a clamping bar 121 in combination with cutters 123,
124 placed at an angle to each other.
7. The complete machine for use in the manufacture of cigarettes substantially
as described or illustrated in the accompanying drawings.
