Improvements in Cigarette Making Machines.
I, ALBERT LEROY MUNSON, of 235 West 76th Street in the City, County and
State of New York, United States of America, do hereby declare the nature of
this invention to be as follows:-
This invention relates generally to machines for making cigarettes; and
particularly to that class of such machines wherein the tobacco in the form of a
continuous filler is enveloped by a continuous wrapper strip to one edge of which
a line of cement is applied so that when the edges of the strip overlap and meet
they will unite completely enveloping the filler to form a continuous cigarette
ready to be severed into short lengths or cigarettes.
Before entering into a detailed description of the construction and operation of
the various instrumentalities which go to form the complete organization illustrated,
it may be stated that such organization embraces first, a means by which the
tobacco is prepared and fed in condition to be operated upon by the cigarette
forming devices, and bereinafter called the tobacco feeding devices, which includes
a vertical tobacco conduit, channel or passage way second, means by which the
loose tobacco fed to the machine is prepared in the form of an endless filler and fed
forward, and hereinafter called the filler-former or filler-forming devices; third,
means by which a wrapper strip is fed in position to be fed forward from a roll or
other source of supply in position to meet the filler to envelope the latter, and
hereinafter termed the wrapper strip paying off or feeding devices; fourth, means
by which the wrapper strip is curved and turned over the continuous filler to
envelope the same, and hereinafter termed the wrapping former or guide which also
includes the cigarette former; fifth, means by which a line of paste is applied
along the edge of the wrapper strip, and hereinafter called the pasting device;
sixth, means by which the continuous cigarette or wrapper strip with enclosed
filler is fed or carried positively forward and hereinafter called the cigarette carrier;
and seventh, means by which the continuous cigarette is severed into cigarette
lengths, and hereinafter called the severing device.
As herein combined the above mentioned several devices co-operate to feed the
loose tobacco to the machine, prepare such tobacco in the form of a continuous
cigarette-filler, feed said filler forward to the wrapper strip, feed the wrapper strip
forward to meet the filler, partially envelop the filler with the wrapper strip, apply
a line of paste to one edge of the wrapper strip, complete the wrapping of the
wrapper strip around the filler, carry the continuous cigarette thus made forward
and sever it into cigarette lengths forming complete cigarettes ready for the
market.
THE TOBACCO FEEDING DEVICES.
The tobacco feeder is mounted in a suitable frame work at the left hand of
the machine, and is arranged to prepare and feed the loose tobacco forward at
right angles to the ultimate direction the prepared filler, wrapper-strip and
completed cigarette move. This feeder consists of two endless aprons and their
respective picker rolls, the aprons being arranged somewhat inclined to carry
the tobacco which may be placed thereon and deliver it into the picker rolls.
The primary apron carries the tobacco into the bite of a picker roll and
an overlying laying roll, said picker roll carrying the tobacco down between
itself and another picker roll from which the once picked tobacco is allowed to fall
onto the secondary apron arranged below said rolls. This apron, shorter than the
other, then carries the tobacco to another pair of picker rolls having also a laying
roll which again pick the tobacco and deliver it into a vertical shute or passage-way
whose lower end directs the picked tobacco between the belts of the filling former.

page_text: The aprons and rolls of the tobacco feeder are driven preferably continuously
from a driving shaft mounted in the machine frame. The picker rolls are formed
by hollow perforated cylinders through which perforations movable picker pins
project, the pins being fixed to cross-rods which are moved radially to project and
withdraw the pins by a suitable cam.
THE FILLING FORMER.
The filler forming devices are located immediately below the exit of the
vertical passageway or shute so as to receive the tobacco delivered therefrom.
These devices consist of three endless belts preferably of metal stretched
around, guided and supported by suitable rolls so as to form a horizontal
trough or channel the sides of which are formed by the active portions of two
belts, and the bottom thereof by the third belt. The operative portion of the
belts forming the sides of the channel are kept to duty and prevented from
spreading by rolls located at intervals between the supporting rolls of the
respective belts, and the belt forming the bottom of the channel is supported by
and moved over a supplementary table also having supporting rolls for the belt,
which table is mounted over the supporting table forming a part of the machine
frame. The tobacco, as before explained, continuously delivered into the vertical
passageway, is received by the horizontal conduit forming the filler former so that
it is carried onward toward the wrapping devices in the onward movement of the
filler forming belts. This movement of the filler forming belts which is a
continuous one, is derived from the main driving shaft through suitable gearing,
which is such that said. belts travel in unison at the same surface speed carrying
the tobacco forward toward the cigarette forming devices. The tobacco carried
along by these belts is pressed or otherwise shaped into rod-form by one or
more presser rolls, the peripheries of which extend into the conduit between the.
helts to hear upon the tobacco being carried forward thereby. In the preferred
construction, these presser rolls are positively driven from any proper part of the
machine as, for instance, from the main driving shaft. The forward presser roll is
provided with a pair of side strippers which act to prevent the tobacco from clinging
to said roll; the strippers being of rotary knife form are driven by proper gearing.
THE WRAPPER STRIP AND CIGARETTE FORMING DEVICES.
The wrapper and cigarette former is mounted in line with the direction of
movement imparted to the tobacco filler by the filler forming belts, previously
described, so that the filler in passing from said belts will be received by the former
to be encased in the wrapper strip to form the cigarette.
The former consists of a
metal guide, the opposite longitudinal edges of which from the entrance end of the
guide are doubled and gradually curve and bend inwardly toward each other until
they merge into a substantially tubular portion one edge overlying the opposite
edge and the doubled edges terminating short of the tubular portion. This
former is of a shape adapted to gradually curve the wrapper strip from a substantial
flat condition in which it enters the former, (the longitudinal edges of which are
received within the doubled edges thereof), to a circular or tubular condition in
cross section with one edge of the strip temporarily standing vertically in position
to lap over onto the other edge. From this point this vertical edge of the former
curves downwardly to direct its edge of the wrapper strip over the underlying edge
of said strip and finally merges into the tubular portion to carry the one edge of
the wrapper strip into firm contact with the underlying portion of the wrapper, thus
having entirely encased the tobacco-filler.
The space between the termination of the filler-former formed by the three belts
and the entrance end of the cigarette former is bridged by a plate supported from
some part of the machine, one edge of which plate overlies the horizontal belt of
the three and its forward edge overlying but not touching the end of the cigarette
former, so that the tobacco filler is properly supported in its passage from the end
of the filler-former onto the wrapper strip passing onto the cigarette former. At

page_text: the entrance end of the cigarette former immediately below the forward end of the
bridge plate there is provided a roll over which the wrapper strip is led and from
which it passes into the former beneath the forward end of said bridge plate. In
this manner the wrapper strip is presented and passes onto the former separated by
the end of the bridge plate from the tobacco filler that is being conducted along
said plate onto the wrapper strip.
In order to aid the movement of the tobacco-filler from the filler foriner into the
cigarette former, there is provided at this point a pair of intermediate side belts
which extend on opposite sides of the bridge plate and aid in properly forwarding
the tobacco-filler into the former. These intermediate carrying belts are properly
driven continuously from the main driving shaft.
.
THE PASTE APPLYING DEVICES.
These devices so far as the other features of invention are concerned, may be of
any preferred form. They consist of a vertical fountain supported at the upper end
of a bracket rising from the supporting table. Near the lower end of the paste
fountain there is an opening in its side in which lies a portion of an intermediate
paste roll that has a grooved periphery running continuously in contact with the
periphery of the paster roll, the periphery of which latter roll runs in contact with
the longitudinal edge of the wrapper strip presented by the upturned edge of the
cigarette former. The entrance of the intermediate paste roll, substantially fills
the opening in the side of the paste fountain so that there shall be no escape of the
paste therefrom, but there may be provided suitable wipers bearing against the
periphery of the roll to regulate the amount of paste that is permitted to adhere to
the periphery of said roll to be carried and fed to the periphery of the paster roll
to be by it applied to the edge of the wrapper strip. As the intermediate roll is
grooved the wiper may be arranged to leave the paste in its groove, so that the
depth of said groove will determine the quantity of paste supplied to the paster
roll, the peripheral edge of said paster roll being small enough to take into the
groove. The paster roll is continuously rotated in contact with the edge of the
wrapper strip and with the grooved periphery of the intermediate roll by suitable
gearing. To effect the proper supply of paste to the intermediate roll, the fountain
is provided with a weighted follower above the paste therein to continually force
the paste into contact with said roll. This follower may be moved downward either
continuously from some moving part of the machine or by hand through a
Screw rod.
The wrapper strip as it passes along through the cigarette former with the
tobacco filler lying thereon and being fed at the same surface speed as the wrapper
strip is carried will be first partially wrapped around the filler, whereupon one
longitudinal edge of said strip will be supplied with a line of paste from the paster
roll, and said pasted edge of the strip in passing into the tubular portion of the
cigarette former will be folded down or lapped over the underlying edge of the
strip so as to be united thereto and thus completely enclose the filler which issues
from the end of said tubular portion of the former fully wrapped in the condition
of a continuous cigarette.
THE CIGARETTE CARRYING DEVICES.
The cigarette carrier is mounted immediately beyond the end of the cigarette
former and in position to receive the completely formed and continuous cigarette
and to grasp and carry the same forward in a straight line with the filler-former
and cigarette-former previously described. This cigarette carrier consists essentially
of a pair of endless elastic grooved carrying belts stretched around suitable rollers
having co-acting stretching rolls to take up any slack in the belts. Each of these
belts is so formed as to provide a longitudinal semi-circular recess, throughout the
length of the belt, the recess of one belt coacting with that of the other belt to
form a continuous and unbroken cigarette grasping and carrying tube. Each

page_text: As the continuous cigarette issues from between the carrier belts of the cigarette
carrier it is received and temporarily supported by a short semi-tubular guide near
the extremity of which is mounted the severing device. This severing device is
in position and operates to sever the continuous cigarette into cigarette lengths
as the continuous cigarette moves onward from between the carrying belts. So
far as other features of the present invention are concerned, the severing device
may be of any of the well known forms, but its novel construction provides an
efficient means by which the continuous cigarette is severed without disfiguring or
buckling the cigarette lengths. This severing device consists of a rotary or
vibrating and laterally reciprocating cutter-carrier in which is mounted one or more
cutters. In the rotary form the carriage is carried in guideways on the upper end
of a rotary support that is secured to a vertical shaft supported in upper and lower
bearings. Where two cutters are employed they will be mounted to rotate in
bearings on diametrically opposite sides of the carriage, the distance of travel from
one cutter to the other representing the length of an ordinary cigarette supposing
that the speed of revolution of the carriage is substantially the speed of movement
of the continuous cigarette; and each cutter will be revolved by a belt extending
around a pulley on its shaft and thence around a pulley secured to a cross shaft
mounted in bearings near the lower end of the vertical shaft. Rotary motion is
communicated to the belt pulleys and thence to the cutters during the revolution of
the carriage by means of a stationary dise the upper surface of which is borne
upon by a frictional wheel secured to the cross-shaft of the belt pulley. The
revolution of the carriage is imparted from the main driving shaft through bevil
wheels.
The cutter carriage during its revolution is forced laterally across the cigarette
path to cause one or the other of the cutters in succession to sever the cigarette by
a spring acting upon one or the other of a pair of pins projecting from the upper
side to the cutter carriage. The action of this spring is controlled by a stationary
cam secured to the bracket which extends in the path of an arm, one for each
cutter projecting from the cutter carriage, which, as the carriage is revolved
restrains the action of the spring until the instant it is desired to throw the rotary
cutter laterally across the path of the continuous cigarette. The moment the
cutter arrives in proper alignment with the cigarette the arm leaves the cam and
the spring suddenly projects the carriage and the cutter laterally so that the latter
immediately severs the cigarette while it is moving along in the same direction and
speed as the cigarette. In order to confine the cigarette to the cutter at the time
it was being severed, the carriage carries adjacent each cutter a cigarette support
which consists of a spring pressed finger, pivotally mounted to the cutter carriage

page_text: alongside of the cutter with its forward end bifurcated to straddle the active
portion of the cutter and also to partially surround the cigarette on both sides of
the severing point. The inner end of the finger during the revolutions of the
carriage moves under a cam fixed at the end of the bracket of such shape that
the instant the cutter and carriage are moved laterally to throw the cutter across the
cigarette the finger is released from the cam and its outer end immediately embraces
the cigarette to steady it and confine it to the cutter as it is being severed thereby.
The severed cigarette length falls from the finger and cutter into any proper
receiver or receptacle. As the carriage revolves the inner end of the finger again
arrives under the cam and is moved to its upper rocked position ready to be again
tripped to embrace the cigarette at the point of the next severance. The finger of
the other cutter acts in a similar manner.
In the other form of severing device the single rotary cutter is mounted in a
horizontally swinging or vibrating carriage loosely held at the upper end of a
pivotted arm, the lower end of which is acted upon by a revolving can driven from
the main shaft. The vibrating carriage is provided with a downwardly extending
shaft having a universal joint to compensate for the different lateral positions of
the pivotted arm and the shaft. is vibrated by a link connection at its loose end,
with a revolving crank disc also driven from the main shaft. The construction is
such that the cam moves the rotary cutter across the cigarette to sever it and while
it is doing so the crank is moving the cutter in the direction of the movement of
the cigarette so that the cutter is travelling with the cigarette as it is severing it.
The vibration of the cutter and its carriage is short and the return vibration brings
the cutter back into position to be again moved laterally across the cigarette to
sever it.
THE WRAPPER STRIP FEEDING DEVICES.
It is obvious that the wrapper strip may be supplied to the cigarette former in
any suitable manner and hence no detailed description thereof is necessary.
The operation of the improved machine in detail has been stated in describing
the several parts, and hence no farther description of the same is deemed necessary.
It will be understood, however, that the operation of the machine is continuous,
that is to say, the tobacco prepared by the feeding devices is fed continuously into
the vertical passage way and thence delivered into the, conduit formed by the
continuously moving filler forming belts to be formed into rod-form adapted to
form the filler of the cigarette; from such belts the tobacco filler is continuously
moved on to the wrapper strip and encased thereby in passing through the former;
is continuously carried onward by the carrier in the form of a continuous cigarette,
and is finally severed into proper cigarette lengths by the severing device ready to
be assembled in packages for the market.

The machine comprises the following parts. First, means by which the tobacco
is prepared and fed in condition to be operated upon by the cigarette forming
devices, hereinafter called the tobacco feed, which includes a vertical tobacco
conduit, channel or passage way; Secondly, means by which the loose tobacco fed
to the machine is prepared in the form of an endless filler and fed forward, herein-
after called the filler-foriner. Thirdly, means by which a wrapper strip is fed in
position to be fed forward from a roll or other source of supply in position to meet
the filler to envelop the latter, and hereinafter termed the wrapper strip feed.
Fourthly, means by which the wrapper strip is curved and turned over the
continuous filler to envelop it hereinafter termed the wrapper former which includes
the cigarette former. Fifthly, means by which a line of paste is applied along the
edge of the wrapper strip, and hereinafter called the pasting device. Sixthly,
means by which the continuous cigarette or wrapper strip with enclosed filler is fed
or carried positively forward, hereinafter called the cigarette carrier. Seventhly,
means by which the continuous cigarette is severed into cigarette lengths, and
hereinafter called the severing device.
The above mentioned several devices cooperate to feed the loose tobacco to the
machine, to prepare such tobacco in the form of a continuous cigarette filler, to
feed the filler forward to the wrapper strip, to feed the wrapper strip forward to
incet the filler, to partially envelop the filler with the wrapper strip, to apply a
line of paste to one edge of the wrapper strip, to complete the wrapping of the
wrapper strip around the filler, to carry the continuous cigarette thus made forward
and to sever it into lengths each forming a complete cigarette ready for the market.
The various devices are mounted upon a supporting table A, from which is also
supported a main driving shaft B.
The detailed description of the various devices forming the machine may be
best understood by describing each of the devices in order.
FIRST. THE TOBACCO FEED.
The tobacco feeder C is mounted in a suitable framework, see Figs. 1, 2 and 3,
rising from the machine table at the left hand of the machine, and is arranged to

page_text: prepare and feed the loose tobacco forward at right angles to the ultimate direction
of the prepared filler, wrapper strip and completed cigarette.
A primary apron 21 is stretched around a roller 22 and a smaller roller 23,
journalled in the framework 20, and is tightened by a roll 22" mounted in a pair of
pivotted arms 22 adjusted by a setting screw 22º. An upper roll 24 immediately
beyond the roll 23 acts with the apron to carry the tobacco onto the roll 25 the
one of a pair of picker rolls 25, 26. These picker rolls separate or loosen the
tobacco fed to them by the primary apron so that when it falls from them onto
the secondary apron 27, it is loosened with its fibres more or less separated. The
secondary apron 27 which is immediately below the picker rolls 25, 26, and is
stretched around rolls 28, 29, that are mounted in the framework 20, and at the
upper inner end of the apron 27 there is a grooved roll 30 and immediately below
it and beyond the end of the apron there is mounted a pair of picker rolls 31, 32,
which receives the tobacco fed to them by the secondary apron and separate and
further loosen it and permit it to fall or deliver it onto a vertical passage way (1
that leads at its lower end to the filler forner hereinafter described. The grooved
roll 30 allows the picker pins of the picker roll to enter beyond its periphery so as
to take the tobacco that may cling to its surface and thus enable the tobacco to be
laid evenly and solidly onto the picker rolls in the best shape for the picking action
of such rolls.
Motion is imparted to the aprons and rolls above mentioned from a counter
shaft B', see Fig. 3, driven by wheel 36 and pinion 35 from the main shaft B and
carrying a driving pulley 33. On the main shaft. 13 is a pulley 37 from which,
through a belt 38 and pulley 39, motion is imparted to an intermediate shaft B
having a pulley 41 from which by a belt 44 is driven a pulley 45 on the shaft of
the apron roll 28. On the countershaft Ba pulley 40 by a belt 42 drives a
pulley 43 on the shaft of the picker roll 26. A belt 50 drives a pulley 51 on the
shaft of the apron roll 22 and a pulley 54 on this shaft by a belt. 55 drives a pulley
on the shaft of the picker roll 25 and by gearing also drives the upper roll 24 anil
an intermediate laying roller 25ª, The shaft of the apron roll 28 also carries a
pulley 60 which by a belt 61 drives a pulley on the shaft of the picker roll 31 and
by a gearing 63 drives the grooved roll 30. The shaft of the picker roll 26 carries
pulley 57 which by a belt 58 drives a pulley on the shaft of the picker roll 59.
For these driving pulleys and belts may obviously be substituted sprcoket wheels
a
and chains.
The tobacco spread by hand upon the primary apron 21 is fed forward beneath
the roll 24 onto the picker roll 25 and between it and the picker roll 26 which pick
loosen and otherwise operate upon the tobacco so that it falls in a separated or
loosened state upon the secondary apron 27 by which it is again fed forward
beneath the roll 30 into the picker roll 31 and between it and the picker roll 32 so
that it is again picked and loosened and delivered into the passage way or
channel C. The roll 32 is provided with a shield 65° preventing escape of tobacco.
The picker rolls 25, 26, may be provided with an intermediate deflecting roll 25
which tends to direct the tobacco down between them, and the other picker
rolls 31, 32 may be provided with an intermediate deflecting plate or with
fingers 31 for a similar purpose. Each picker roll or only one of each pair may
be constructed as shown in Figs. 11 to 16, a hollow cylinder or shell a has holes in
its periphery through which rows of picker pins are protruded and retracted.
These pins project from rods e, the ends of which project through slots in the
heads a of the cylinder a, and engage with a pair of cams e, fixed at each end of
the roll. As the picker roll rotates the ends of the rods e successively leave the
concentric portion of the came which normally holds the pins protruding and travel
along the straight portion, Fig. 13, by which the rods are drawn in retracting the
pins within the periphery of the roll and thus effectually stripping off any tobacco
that may cling to the pins, and permitting it to fall onto the secondary apron 27 or
the vertical passage way C. The ends of the rods then successively leave the
straight portion of the cams, and enter their concentric portions being thus again

page_text: moved outward and causing the pins to project from the periphery of the roll ready
for the succeeding picking operation. For tobacco of very long fibre it is
sometimes necessary to employ more than two sets of picking rolls with these
aprons.
The passageway C receives the loose tobacco from the secondary apron and
directs it into the conduit forming the filler former now to be described.
THE FILLER FORMER.
The filler forming devices D consist of three endless belts 89, 90 and 91,
preferably of metal stretched around, guided and supported by suitable rolls so as
to form a horizontal trough or channel, the sides being formed by the belts 89, 90
and the bottom by the belt 91 which moves over a supplementary table A' and
over a number of anti-friction rolls 91 Fig. 4. The tobacco is received by the
horizontal conduit forming the filler former and carried onward toward the
wrapping devices by the continuous imovement of the belts which are driven as
follows. The main driving shaft B through a pair of bevel wheels 93, 100 drives a
short vertical shaft that carries at its upper end one of the pulleys around which
the belt 90 is stretched. The same short vertical shaft drives a horizontal cross
shaft through a pair of bevel wheels 101 which convey motion to a similar vertical
shaft carrying at its upper end one of the pulleys around which the belt 89 is
stretched. The third belt 91 is driven from the said horizontal cross shaft through
gears 102, 103 and 104, the latter being on the shaft carrying one of the pulleys
around which the belt 91 passes. The tobacco carried along by these belts is
pressed or otherwise shaped into rod form by the gradual approach of the side belts
toward one another and by one or more presser rolls 105, the peripheries of which
extend into the conduit between the belts 89, 90 and bear upon the tobacco as it is
carried forward. The roll or rolls 105 is or are carried by a frame 107, adjustable
by a screw 103 to regulate the pressure upon the tobacco. These presser rolls are
by preference positively driven from any proper part of the machine, as, for
instance from the cross shaft carrying the gear wheel 103. A sprocket or pulley 94
on this shaft drives a sprocket or pulley 95, which by a chain or belt drives a
sprocket or pulley 96 on the shaft carrying one of the pressing rolls 105 from
which shaft the other pressing roll is driven. One of the presser rolls 105 is
provided with a pair of side strippers 106 in the form of thin dises mounted one on
cach side of the roll in close contact with its sides so as to strip off any tobacco that
may cling to the roll. These strippers are driven much faster than the presser roll
by a train of gearing 109 from the shaft of the roll.
THE WRAPPER STRIP AND CIGARETTE FORMING DEVICES.
The wrapper and cigarette former F is mounted in line with the channel
formed by the belts 89, 90, and 91 so that the filler in passing from this channel
is received by the former F to be encased in the wrapper strip to form the
cigarette.
The former F, see Fig. », consists of a metal guide, the edges 70, 71 of which
are doubled, and gradually curve and bend inwardly toward each other until they
emerge into a tubular portion 72, the edge of 70 overlying the edge of 71, the
doubled edges terminating short of the tubular portion. The wrapper strip
entering in a flat condition under the doubled edges 70, 71 is coiled into a tubular
condition with one of its edges lapping over onto the other edge the tubular portion 72
pressing the one edge of the strip into firm contact with the underlying edge, thus
encasing the tobacco filler.
The space between the termination of the channel formed by the belts 89, 90
and 91 and the entrance of the former F, see Fig. 4 is bridged by a plate 11
which supports the tobacco filler in its passage from the end of the channel onto the
wrapper strip in the former F. At the entrance end of the former F immediately

page_text: each belt being moulded as an endless belt so that there is no joint in its length
such as would cause irregularities in the cigarette grasped between the belts.
The belts 140, 141, are driven from the main shaft B through bevel gearing 150,
a short vertical shaft 150, bevel wheels 151, 151, and wheels 152, 152, on the
shafts of the rolls 144, 146.
THE SEVERING DEVICE.
As the continuous cigarette issues from between the belts 140 and 141, it is
received and temporarily supported by a short semi-tubular guide near the extremity
of which is arranged the severing device I which severs the continuous cigarette
into lengths. The severing device may be of any of the well known forms but
that preferred is shown in Figs. 6 to 10, and consists of a revolving cutter 161
mounted in a cutter head 162 arranged to vibrate and oscillate in a horizontal plane
across the line of continuous cigarette. The cutter head 162 has a bearing 164
journalled to swing horizontally in the upper end of a rocking frame 160 which is
formed with pivots 160 journalled in a bracket 160° on the under side of the table A,
see Fig. 6. On one leg of the frame 160 is mounted a roller which is held against
a revolving cam 173 by a spring, 170, see Fig. 7. By this cam the frame 160 is
rocked at stated intervals to move the cutter 161 suddenly across the cigarette
severing it into suitable lengths. The cam 173 is on a short longitudinal shaft 176
driven from the main shaft B by a gear 181, intermediate 182, and gear 183 on the
shaft 176 which also carries a pulley 169 and this through a belt 165 drives the
pulleys 167, on a lower counter-shaft, whence a belt 166, extends up to a pulley on
the cutter shaft.
The bearing 164 of the cutter head is at the upper end of the vertical shaft 163
which is connected by a universal joint 163° with a shaft 163. This shaft 163ª has
an arm 163 connected by a link 180 with crank disc 179 and thus the cutter head
is caused to swing horizontally in the direction of movement of the cigarette and
back again besides having the lateral crosswise movement. Motion is imparted to
the disc 179 through a bevel gear 178 and 177 from the shaft 176. Owing to the
two combined movements of the cutter head, the cutter severs the continuous
cigarette into lengths while the cigarette is in motion without breaking the paper
or buckling the severed ends.
The guide 172 is carried by a longitudinally movable slide 155 mounted in guides
at the upper end of a portion of the frame A². The underside of the slide is
loosely connected by a link 154 with the cutter head 162.
THE WRAPPER STRIP FEEDING DEVICES.
As the wrapper strip x may be supplied to the former F in any suitable manner
no detailed description is necessary. As shown in Fig. 1 it is supplied from a
roll X and led upward to the roll 112, see Fig. 4ª.
The operation of the improved machine has been stated in describing the several
parts, from which description it will be understood, that the operation is continuous,
that is to say, the tobacco is fed continuously into the vertical passage way C₁, and
thence delivered into the conduit formed by the filler forming belts and formed into
rod form, which is continuously moved onto the wrapper strip and encased thereby
in passing through the former F; thence it is carried onwards by the carrier H in
the form of a continuous cigarette, and finally it is severed into suitable cigarette
lengths by the severing device I.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination of tobacco feeding aprons, pairs of picker rolls one or both
of a pair having movable picker pins and means for protruding and withdrawing
them, substantially as described.

page_text: 2. In a tobacco picker roll having a perforated periphery, a number of rods
having pins projecting through the perforated periphery in combination with a
cam arranged to cause the rods to move to and from the axis of the roll as it
revolves, substantially as described.

3. The combination of the three belts and pressing rollers, the bridge plate, the
pair of intermediate belts and the former for advancing the column of tobacco onto
the wrapper strip, and forming the continuous cigarette, substantially as described.
4. The combination with the cigarette former of the paste fountain, the grooved
paste roll and the transferring paster roll, substantially as described.
5. In combination with the cigarette former, and pasting device, the pair of
elastic belts, having hollows embracing the cigarette, substantially as described.
6. In combination with the cigarette forming devices, the horizontally oscillating
and laterally moving cutter for severing the cigarette into lengths, substantially as
described.
