A. New or Improved Endless Cigarette Making Machine.
1, HERMANN KORTE, of 125 Grüner Weg, Wahlershausen near Cassel in the
Empire of Germany, Engineer, do hereby declare the nature of this invention to
be as follows:
This invention relates to a new or improved endless cigarette making machine,
by means of which an endless tobacco rope is continually compressed and enveloped
in an endless paper band and the seam of the latter is closed by a folding arrange-
ment without applying any paste at all.
On the table or ground plate of the machine are trestles for supporting an
adjustable forming channel, which is flat at the front end to facilitate the entrance
of an endless feed belt and of the endless paper band. From the front end to the
back end the channel is hollowed out conically for compressing the endless tobacco
rope and it is open at the top. In this opening a steel tongue is fastened at a
certain distance from the inside of the forming channel, so as not only to gradually
compress the endless tobacco rope, but also to leave on both sides narrow passages
for the edges of the endless paper band. The feed belt serves to draw the endless
paper band and the endless tobacco rope through the forming channel. The endless
paper band gradually envelopes the endless tobacco rope and its edges guided in
the said narrow passages continually rise and approach to each other over the face
of the steel tongue. Near the back end the steel tongue is secured on the forming
channel by a traverse, which on its underside is provided with two deep cuts
converging towards the back end. On arriving before this traverse the edges of
the paper band are obliged to bend upwards in order to travel through the said
deep cuts. Here they are drawn nearer and nearer until on the exit they touch
each other. To the back end of the forming channel a piece is secured, which is
bored cylindrically and made in two halves, leaving a narrow slit at the top.. On
entering this slit the paper edges are folded, so that they stand quite vertically.
Above the slit the back end piece is provided with two inclines sloping to the slit.
In the furrow thus formed an elastic die is fitted, which on its underside is provided
with a conical furrow converging towards the exit. The folded vertical paper
edges on arriving near the die are obliged by its conical furrow to bend and on
passing this furrow to roll more and more. The back end piece is sharpened so as
to bring the compressed and enveloped tobacco rope quite near to a pair of rope
pulleys, which draw the feed belt with the paper band and the tobacco rope out of
the forming channel. The rope pulleys are made in halves so that they can be
adjusted to fit the diameter of the endless cigarette. They revolve on vertical
axles which are made adjustable vertically, and one of them can be turned side-
wards round the axis of the pivoted lower bearing. On the two axles immediately
above the rope pulleys are fixed two folding discs, which are finely toothed at the
circumference and work together. There is a press screw provided with a spring
to press the two folding dises tightly together. The rolled seam of the paper band
on leaving the furrow in the die above the back end piece is caught by the fine
teeth of the folding discs and folded in a zigzag or serpentine line, so that the seam
is now prevented from opening again. Behind the folding discs, and the rope
pulleys a feed roller on the driving shaft is, fastened, which drives the endless feed
belt. Ahove the feed roller a press roller is arranged in a frame pivoted at the
head plate of the machine. By means of a press screw in a turnable arm this press

page_text: roller is made adjustable so as to press the endless cigarette more or less and to
Jevel the folded seam. The press roller is driven from the feed roller by means of
a long pinion, into which the feed roller and a wheel at the press roller gear. There
are suitable wheels and bevil wheels for transmitting the motion of the driving
shaft to the two vertical axles, whereby the two folding discs are moved. On the
axles are two wheels, of which the one is a little larger than the other, so as to
cause the latter and the one rope pulley connected thereto to run a little quicker
than the folding discs. The other rope pulley is driven from the first one by
wheels of equal diameters. Thus a velocity of the mean circumference of the rope
pulleys is obtained, which is like that of the teeth of the folding discs and like that
of the endless cigarette. The endless feed helt is kept in tension by means of two
rolls, the one of which is pressed down by a weighted lever. To prevent the feed
belt from slipping, the feed roller is finely rifled and more over the following device
is employed. One of the wheels transmitting the motion of the driving shaft to
the vertical axles is made to slide on the boss of another wheel, while by a feather
it is obliged to partake in the revolution of the other. Above the wheel an india
rubber ring is fastened in a suitable manner, which touches the feed belt from below
at the feed roller. Below the wheel a weighted lever is pivoted, which at its
shorter arm is provided with a friction roll bearing against the said wheel. Thus
the pressure of the weight is transmitted through the friction roll, the wheel and
the india rubber ring to the feed belt. The endless feed belt consists in one or
several layers of tracing cloth pasted one on the other and with the ends butting
at each other, so that it is of an equal thickness throughout. The driving shaft of
the machine may be turned either by hand or through some suitable means from a
machine making the endless tobacco rope.

A NEW Or improved Endless Cigarette Making Machine.
I, HERMANN Korte, of 1254 Grüner Weg, Wahlershausen near Cassel in the
Empire of Germany, 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 relates to a new or improved endless cigarette making machine,
by means of which an endless tobacco rope, i.e. an endless rod of loose tobacco or
tobacco fillings is continually con pressed and enveloped in an endless paper band
or wrapper and the seam of the latter is closed by a folding arrangement without
applying any paste at all.
And in order that my invention may be fully understood and readily carried into
effect will now proceed to describe the three sheets of drawings accompanying
this my Complete Specification, reference being had to the figures and letters marked
thereon.
Fig. 1 is a ground plan of my new or improved endless cigarette making machine,
Fig. 2 a side elevation thereof, Fig. 3 an end view,
Fig. 4 a cross sectional view, taken in the plane of the line n―o in Fig. 1,
Fig. 4 a view of the lever 03 in Fig. 4 from below,
Fig. 5 a cross section, taken in the plane of the line p-q in Fig. 1,
Fig.
a cross section through the line r-s in Fig. 1,
Fig. 7 a vertical longitudinal section through the line t--u in Fig. 1,
Fig. 8 a horizontal sectional view taken in the plane of the line -w in
Fig. 7, and
Fig. 9 to 200 show parts of the machine, which will be referred to later on.

page_text: On the table or ground plate A (Figs. 1, and 7) of the machine are
trestles A and A2, upon which the forming channel B is made vertically and
sidewards adjustable by means of the set screws B¹ B* B³ B.
On the four columns U U erected on the table A a head plate U is fastened
for the purpose of holding the two axles QQ¹ (Fig. 5). The one axle Q, pivoted
in the bearing S² on the table A and in the bearing S in the head plate U, is made
adjustable by means of the screws Q2 in the bracket A* and U2 in the plate U' on
the head plate U. In a similar manner the other axle Q', pivoted in the box S³
and in the bearing S1, is made adjustable by means of the screws Q2 and U2. On
the axles QQ two folding discs or crimping wheels R R are fastened, which are
finely toothed at the circumference and work together.
Immediately under the crimping wheels R R are two rope pulleys or forming
wheels, which revolve on the axles QQ and consist in the upper halves X X and
in the lower halves X'X'. The latter are threaded in the borings to fit to the
equally threaded bosses of the upper halves XX, so that they can be moved up
and down, their lower parts X2 X2 being outside formed like nuts (Fig. 2). In
this manner the furrows at the periphery of the rope pulleys or forming wheels
can be regulated or adjusted to fit the diameter of the endless cigarette H¹.
The machine is driven by means of the shaft M (Fig. 1), which may be turned
either by hand or through some suitable means from a machine making the endless
tobacco rope or rod of loose tobacco. The motion of the shaft M is transmitted
through the bevil wheels N and N' (Fig. 4) and the gear wheels P and PI (Fig. 2)
to the axles Q Q'. When the machine is driven, not only the folding dises
or crimping wheels R R revolve, but also the rope pulleys or forming
wheels XXX X', to which the motion is imparted through the gear wheel V
fastened on the axle Q and through the gear wheels V W W sitting on the bosses
of the forming wheel halves XX. The two gear wheels W W are alike, while
For this reason the rope
the gear wheel V is a little larger than the other V¹.
pulleys or forming wheels X X X X run a little quicker than the folding discs or
crimping wheels R R, and in such a manner, that the velocity of the mean
circumference of the rope pulleys or forming wheels X X X X' is like that of
the teeth of the folding discs or crimping wheels R R and also like that of the
endless cigarette H'.
The forming channel B is shown on an enlarged scale in Figs. 9 to 15, of which
Fig. 9 is a vertical longitudinal section, Fig. 10 a cross section through the
line a-b in Fig. 9, Fig. 11 a cross section through the line c-d, Fig. 12 a cross
section through the line e-f, Fig. 13 a cross section through the line g-h,
Fig. 14 a cross section through the line i-k, aud Fig. 15 a cross section through
the line l-m.
The forming channel B is open at the top (vide Fig. 1) and is covered with a
steel tongue D. At the front end it is flat as shown by Fig. 15, to facilitate the
entrance of the endless feed belt or apron I and of the endless paper band er
wrapper G, which latter is introduced over the guide roll G. The channel B is
hollowed out conically about from trestle A' to trestle A2 for gradually compressing
the endless tobacco rope or rod H of loose tobacco. The end piece C secured to
the back end of the forming channel B by means of the screws CCC (Figs. 16,
17 and 20), is, however, bored cylindrically and made in two halves, leaving a
narrow slit C³ at the top. The endless feed belt or apron I serves to draw the
endless rod H of tobacco fillings and the endless paper band or wrapper G through
the forming channel B. It goes over the flat front end of the channel B into the
latter and round the feed roller or pulley K (Figs. 7 and 8). The two traverses
or cross bars D'D', fastened on the channel B by means of the screws D'D',
serve to hold the steel tongue D.
The one traverse D' at the back end of the channel B is on its underside
provided with two deep cuts D³ D³ (Figs. 12 and 19), which converge in the
direction to the end piece C. To the traverse or cross bar D' the steel tongue D
is fastened only in the face shown hatched in Fig. 19. The steel tongue D is kept

page_text: at a certain distance from the inside of the forming channel B, so as to leave on
both sides narrow passages for the edges of the endless paper band or wrapper G,
see Figs. 14, 13 and 12. Thus the steel tongue D not only compresses the
fillings H, as they proceed in the channel B, but also it enables the endless paper
hand or wrapper G to gradually envelop the endless tobacco rod, while the edges
of the wrapper guided in the said narrow passages continually rise and approach to
each other over the upper surface of the steel tongue. On arriving before the
traverse or cross bar D³ the edges of the paper band or wrapper G are obliged to
bend upwards in order to travel through the deep cuts D³ D³ (Fig. 12). Here
they are drawn nearer and nearer until on the exit they touch each other.
As said above the end piece C has at the top a slit C³, which is shown in Fig. 16
exaggerately wide for the sake of clearness, while in reality it is so narrow as to
allow only of the two paper edges passing through. The top face of the end
piece C is a little above that of the channel B and is provided witl: two inclines C⭑
sloping to the slit C³. Into the furrow thus formed a die F (Figs. 9 to 11) is
fitted. It is fastened yieldingly to the spring E and is provided on its underside
with a conical furrow F1 converging towards the exit. The spring E is connected
with the cross bar D2 and made adjustable by means of the set screws E' E2. It is
capable of being bent a little upwards, so as to clean the furrow F of the die F.
The spring E may also be fastened to the cross bar D³, if so preferred, in which
case the one short set screw E' is replaced by a long screw.
The steel tongue D
reaches a little beyond the cross bar D and into the end piece. C.
The end piece is sharpened as shown in Figs. 8, 16 and 17, in order to bring
the compressed and enveloped tobacco quite near to the rope pulleys or forming
wheels XXXX, which draw the. feed belt or apron I with the paper. band G
and the tobacco out of the forming channel. B.
As already mentioned, the edges of the endless wrapper G. touch each other on
leaving the cuts D³ D3 of the cross bar D2. When further proceeding, they enter
the narrow slit (and are thereby folded, so that they stand quite vertically. On
arriving near the die F, they are obliged by its conical furrow F1 to bend and on
passing this furrow to roll more and more. On leaving the die F the rolled seam
of the wrapper G is caught by the fine teeth of the folding discs or crimping
wheels R K and indented or crimped so that the seam is now prevented from
opening again. To ensure this purpose, the lower end of the axle Q (Fig. 5) is
fitted in a box S³, which can turn on the two pins S sidewards, while the upper
end is in a bearing S¹, which is pressed with the spring T2 by means of the
screw T. Thus the two folding dises or crimping wheels R R are pressed
together, so that their teeth crimp the wrapper seam tightly.
Above the feed roller or pulley Ka press roller Y (Fig. 7) is arranged in a
frame Y2, which is linked at Us (Fig. 1) to the head plate U by the pin Y1 and
is made adjustable by the press screw Z³. The latter is in an arm 7, which can
be swung about on the column Z. On the axle of the press roller Y a gear
wheel Y is fixed, which gears into the long pinion Y (Fig. 4). The feed roller
or pulley K is also toothed at one side and gears into the pinion Y, so that its
motion is thereby imparted to the press roller Y. To ensure a good working of
the machine the pulley K, the press roller Y and the gear wheel Y³ are made of
an equal diameter. The pinion Y is pivoted in an arm Y³, which is adjustable
on the column Z and may be put aside if desired:
The press roller Y serves for levelling the folded and crimped seam of the
endless cigarette H₁ by pressing the latter more or less, and. also, where, wanted,
for flattening the cigarette, i.e. giving it an oval section (see Fig. 4).
When an endless cigarette of another diameter is to be. made, the forming
channel B will have to be replaced by another oue and the forming wheels XX
XX are re-adjusted to fit to the diameter of cigarette.
The endless feed belt or apron I is kept in tension by means of the two rolls I
and I. The one roll 11 (Fig. 7) revolves on the shaft L³ (Fig. 6), which is
pivoted in the bearing L' and carries at the one side the short lever. L' (Fig. 2)

page_text: and at the other side the ratchet wheel L. On the boss of the bearing L' t'e
lever L is turnable, which carries the weight L' and is provided with a pawl L'
at the short arm L. Thus the pressure of the weight L' is transmitted through
the lever L, the pawl L, the ratchet wheel Le, the shaft L³, the lever L2 and the
roll 12 to the feed apron I. To prevent the feed apron I from slipping on the
feed roller or pulley K, the latter is finely serrated and more over the following
device is employed to press the feed apron against the pulley K. The bevil
wheel N turning round the bolt A³ (Fig. 4) has a long boss, on which the gear
wheel P slides up and down, while it is obliged by a feather to partake in the
revolution of the bevil wheel N. On the gear wheel P an india rubber ring O,
which touches the feed apron I at the pulley K, is fastened in a suitable manner,
while on the pins 02 below the gear wheel P the lever 03 is turnable, which carries
at the longer arm the weight 0₁ and at the shorter arm the friction roll O' bearing
against the gear wheel P. It will now be seen, that the pressure of the weight O
is transmitted through the lever 0³, the friction roll O¹, the gear wheel P and the
ring O to the feed apron I.
The endless feed belt or apron I is made of two or several layers of tracing
cloth pasted one on the other in the manner, that the ends of the tracing cloth
strips in every layer butt at each other and the butts in one layer do not coincide
with those in the next layer. Thus an endless apron is obtained, which is
throughout of the same thickness and lasts much longer than an apron with sewn
joints would, because the joints of the latter are not only thicker, but are also
liable to wear and tear.
Owing to this construction of the feed apron I the latter cannot be inserted in
the channel B through the narrow slit C (Fig. 16). Therefore, as already sai!,
the end piece C is made in two halves, which are united by the screw C (Figs. 9,
17 and 20). To insert the feed apron I in the channel B, one half of the end
piece C is taken off, then the apron is introduced and afterwards closed in by
putting the half on again.
The rope pulleys or forming wheels X X X X' may be covered at the
circumferences with india rubber, in order to better draw the feed apron I with
the wrapper G and the endless tobacco rod out of the forming channel B.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
