COMPLETE SPECIFICATION.
Improvements in Cigarette Machines.
I JAMES ALBERT BONSACK of 1328 Chestnut Street Philadelphia in the State
of Pennsylvania U.S.A. do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The mechanisms described and claimed in the following specification may be
variously modified, and, therefore I do not desire to limit my invention to the
construction specifically described and shown in this specification. Thus, I am
aware, that in lieu of seaming the conical wrapper by interlocking and crimping the
edges of the same, such edges may be otherwise secured together, as by paste or
other adhesive substances; also, that the mandrels upon which the wrappers are
shaped, together with the co-operating seaming mechanism, as well as the dies which
shape the filler, may be of different forms, thus producing cigarettes which may be
angular or oval in cross-section, or of other form than round and cylindrical.
In the following description I shall explain a complete machine as the same is
adapted to manufacture conical cigarettes, but I shall limit myself in the claims
which follow the description of the machine to the particular forms of mechanisms
and combinations of elements which I regard as novel and as of my invention.
In this latter connection, attention is particularly directed to certain of the
mechanisms herein shown and described which cut out, shape and seam the
cigarette wrapper.
The present improvements relate to mechanism for forming individual cigarettes,
that is, the filler and the wrapper of a single cigarette are separately or individually
formed, and are then brought together to produce a completed cigarette. The
improvements relate particularly to the manufacture of cigarettes of other than
cylindrical form, particularly of conical form. By "conical" cigarette, is meant a
cigarette which is in form or the shape of the frustum of a slender cone, or is
conico-cylindrical in shape. The term "conical," as applied to these cigarettes,
having become established in the practical art, is herein employed to describe the
form or shape of the filler, its paper wrapper or shell, and various parts of the
machine. The essential groups of mechanism composing the hereinafter described
machine and which includes the present inventions hereby claimed, are as
follows:
First. Mechanism adapted to receive and at proper intervals intermittently feed
forward a strip or band of paper suitable in form to cut therefrom the wrapper blank
of a cigarette; aud of paper-cutting mechanism adapted to cut from the wrapper
strip a cigarette wrapper blauk of such shape in length and breadth as will adapt
it when it has been conically formed and its inclined edges sealed together; to
constitute the wrapper or shell of a conical cigarette; and also of mechanism
adapted to feed said blank of wrapper paper to the wrapper-shaping and seam-
forming mechanism.
Second. The invention consists of wrapper-forming and seam-forming mechanisms,
which comprise a series of mandrels and dies of conical form substantially the
same as that of the ultimate or finished cigarette, which mandrels and dies are
successively brought to position where the cut cigarette blank is delivered from
the blank cutting mechanism, each mandrel at this place being separated from its
corresponding die and the mandrel and the die being located so that the blank in
the cutting mechanism can be delivered into the die and beneath the mandrel,

page_text: preparatory to the blank being brought to partial conical form or partially wrapped
around the conical mandrel; also, this group of mechanism includes devices for
further conically forming the blank, which devices are in the nature of pincers or
die blocks which are positioned at the place next following the position of the die
and mandrel and beyond the place where they receive the wrapper blank, and which
operate to seize upon the two free edges of the blank, the blank then being held by
the mandrel and its die, and pinch such edges together, thus completing the conical
shaping of the blank, or completing the wrapping of the same entirely around the
mandrel; this group of mechanism further includes a curler or wrapper edges inter-
locking or folding mechanism, which is located and operated so as to, upon movement
of the pincer mechanism longitudinally along the now joined edges of the wrapper,
engage such edges and bend, fold or curl said edges one upon the other, and so that
they engage each other; further, this mechanism consists of a crimping wheel,
which is adapted to follow the curler or wrapper edge interlocking device described
and to press upon the seamed parts, forcing them down upon the mandrel and
crimping or serrating or otherwise causing the curled or folded edges to be brought
into final and permanent engagement.
Third. The machine includes mechanism adapted and operating to successively
strip the formed and completed wrapper or shell from the conical mandrels and hold
uch wrapper or shell in position where a previously formed conical filler can be
inserted in the same; in conjunction with this mechanism, there is also provided
means whereby, if a finished wrapper or shell is for any reason not delivered to this
mechanism, the machine will be stopped, and this latter mechanism acts also to stop
the machine in case a filler is wanting.
Fourth. The machine also includes a hopper mechanism adapted to receive tobacco
of suitable kind and in ordinary bulk form, and acting so that the tobacco is
regularly and uniformly taken from the bulk mass and brought into form of a layer
or stream thicker at one edge than at the other edge thereof by such amounts that
a cross-section of the layer represents the angular outline form of the ultimate
cigarette; also, of mechanism for dividing such layer or stream of tobacco, as it
runs from the hopper mechanism, into separate or individual masses, bunches or
piles, and for separately delivering such masses into a compressing compartment;
also, of mechanism adapted to act upon the filler masses in said compartment to
compress the same into approximately the ultimate form of the filler, and to then
deliver such partially shaped filler masses into die mechanism that finally shapes
and compresses the same.
Fifth. The machine includes a filler molding die-mechanism, which operates to
receive the partially formed fillers and mold the same into ultimate form, that is,
into substantially the same conical shape as the bore of the cigarette wrapper or
shell, this die mechanism being composed of a series of dies which progress inter-
mittently or step by step from the position where they are charged with the filler
to the above described mechanism which operates to strip the formed wrappers or
shells from the mandrels and hold them in position to receive the fillers; and in
conjunction with this die mechanism is provided mechanism for projecting the
forined filler into the formed shell as the said die mechanism successively brings the
formed fillers to position opposite the shell-carrying mechanism.

and the mechanism for feeding the tobacco from the hopper to the filler-compressing
and shaping mechanism being omitted, these mechanisms being shown on other

PAPER FEEDING AND BLANK CUTTING MECHANISM.
Referring now in detail to the machine illustrated by the accompanying
drawings, and first to Figs. 1, 3, 13, 20, 27, 36 and 37, it being understood
that each of the representing numerals invariably represents the same part
throughout all the views of drawing, the numeral 1 indicates the frame work
of the machine and the fixed supports of the various movable parts. The paper
from which the cigarette wrapper or shell is formed consists of a continuous ribbon
or strip 2 wound on a reel 3 and extending from said reel into the machine through
the guide 4 to the feeding rolls 5 and 6 (Fig. 37), one of which rolls, preferably
the upper one and which is held to contact with the lower by springs bearing on its
journals (Fig. 37), has a yielding surface 7 such as would be afforded by the roll
being covered with a thin fabric. The lower roll 6 is driven through shaft 8 on
one end of which is a friction or notched retaining wheel 9 acting to hold the roll
at any position at which it may stop by engaging the spring pawl 10 or similar
retaining device.
On the other end of this shaft 8 and fixed thereto is the ratch cam-wheel 11, as
also the loose gear wheel 12 carrying the spring actuated dug 13 adapted to
engage said ratch, and meshing with pinion 14 which in turn engages the
longitudinal moving rack 15. As this rack moves in the left-hand direction,
the dog is caused to engage the ratch wheel and thereby to rotate the feeding
rolls a half turn, which is in accordance with the length of une cigarette wrapper;
when the rack moves in the opposite direction the feeding rolls stand still and the
gear wheel which hears the dog is turned backwardly and the dog brought to
position to engage the other ratch of the ratch wheel when the rack shall be again
moved toward the left hand.
This rack is attached to the piston 16 of the pump barrel 17, which barrel is in
open communication with the hollow knife arın 21 (to be shortly described) and
through this arm with the nozzle 18 which is located directly above the position

page_text: where the wrapper is cut. The pump piston 16 is caused to force air out of said
nozzle at the proper time for the purpose of blowing away from the machine the
fragments of paper cut from the wrapper ribbon.
As the ribbon of the paper advances beyond the feeding rolls 5 and 6 it passes
between a guide or ledger plate 19 (Figs. 21-23) and a bed 20 of converging
form as seen particularly at 19 in Fig. 22, this bed and plate being of form like
lengthwise edges of the desired wrapper or blank of a single cigarette. The knife
carrying arm 21 is pivotally attached to the machine at 22 (Fig. 3) and carries the
two straight knives 23 and the curved knife 24, these knives being mounted upon
spring-actuated pivotal handle-supports 25 and 26. When, as for the purpose of
adjusting the wrapper strip, it may be desirable to swing this knife arm away from
the guide 19 and bed 20, the operator will seize the handles 25 and 26 and by
pressing upon the same will cause the three knives to move away from and therefore
not drag upon their co-acting cutting parts, which parts are the diagonal edges and
the forward end of the bed 20, see Figs. 21 and 22.
A
One operation of the feeding rolls causes the paper strip to extend along the bed
a distance substantially equal to the length of the knives 23, see especially
Figs. 21 and 27. Before these rolls cause the blank to be again pushed forward
the said knives are caused to descend and shearing against the edges of bed
produce the incisions 25 (Fig. 27) which indicate the side edges of the blank or
the edges subsequently to be brought in contact and seamed together.
subsequent action of the feeding rolls causes this incised part of the paper
strip to be pushed forward to the end of the bed 20, and a repeated descent of
the knife arm causes the lateral blade 24 to make the cut 26 across the strip.
When the strip has again been advanced by the feeding rolls this blade 24 makes
another incision 27 and shears the now formed blank from the strip. At each
descent of the knife-carrying arın, a blast of air is forced from the nozzle 18
against the V-shaped block 19" and thereby directed so that the fragments of
paper sheared from the strip are blown away so as not to clog or otherwise
interfere with the working parts of the machine. 28 represents the wrapper blank
of a cigarette, which blank in general outline is of segmental form. As the ribbon
is moved forward yet another step, the cigarette wrapper blank 28 is projected into
a pocket 29 (Fig. 21), heing carried to the bottom thereof and brought to Hat
unwrinkled position by the timely action of the gravity flap 30, which is allowed
to fall at the proper time by motion in the right-hand direction of rod 31 pivotally
connected to the spring retracted cam arm 32, see Fig. 22.
BLANK SHAPING AND SEAMING MECHANISM.
The wrapper blank is next progressed out of the pocket 29 to mechanism which
conically shapes it and secures its edges together as will be described below. 33 is
a longitudinally moving pusher bar adapted to enter the said pocket, engage the
broader edge of the blank and push the blank out of the pocket. This bar is
frictionally secured by spring 34 to the longitudinally moving slide 35 running
in a groove in the underside of the bed 20. This frictional engagement is provided
so that in case the wrapper shaping mechanism has not had proper motion and so
is not in position to receive the segmental blank, the false engagement of the
pusher bar with such mechanism will not effect any injury, because then the bar
would be free to nove in its carrying slide; in event of such displacement of the
bar, upon its retraction it will be brought to contact with stop 36 and thereby be
caused to replace itself in proper position in its carrying slide. The slide 35 is
operated by the link 37 eccentrically pivoted to the shaft 38, one end of the link
being pivoted to said slide 35 and the other end being pivoted to the guide block 39
running in a transverse guide 40 arranged at right angles to the longitudinal guide
of the slide 35. This slide 35 also engages the spring arm 32 which in proper time
actuates the flap 30.
The shaft 38 carries fixed thereto the horizontal cam wheel 41 the upper

page_text: horizontal edge of which is of the cam shape particularly shown in Fig. 36.
Resting upon the cam periphery of this wheel is a roller 42 carried at the lower
end of a vertical arm fixed to the knife-carrying arm 21. At such time as the
feeding rolls are advancing the paper strip, this cam wheel is operating upon
the knife arm to hold the knives of the same above the guide plate 19 and shearing
bed 20, so that the strip may be readily advanced under the same.
The shaft 38 also carries the gear wheel 43 (Figs. 3 and 13) which meshes
with the gear 44 on shaft 45, which shaft is driven through gears 46 and 47 from
shaft 48. On the lower end of shaft 45 is a crank arm 49 that operates through
link 50, the take-up roll 51 and friction arm 52 which control the paper ribbon as
it is drawn from the reel 3 on which it is wound. The shaft 48 is driven through
gear 53 and pinion 54 by shaft 55, which in turn is driven by belt 56, running on
belt wheels 57 and on wheel 58 of the countershaft 141.
60 (Figs. 4, 6, 21 and 22) indicates the circular head which carries the four
mandrels 61 around which the wrapper blanks 28 are successively conically formed,
their opposite slanting edges being brought together and securely seamed. Each
pair of these mandrels is fixedly mounted upon a slide plate 62, the plates of the
separate pairs crossing each other as shown in Figs. 4, 21 and 22, the plates being
properly centrally slotted so as to have radial motion in the head and without
interference with the axle shaft 63 of the head, which shaft at its outer end
carries the gear wheel 64 meshing with the star cam wheel 65 which is driven
step-by-step by the crank arm 66 on the end of the shaft 48, see Figs. 1 and 42.
The plates 62 that carry the mandrels are frictionally held in place by a spring 67
surrounding the shaft of the mandrel head and pressing the head plate 68 against
said mandrel plates. Beneath each mandrel is located a die 69 (Fig. 21) of form
corresponding to the conical shape of the maudrel, and in the head and with the
die as a central line or part thereof is located one for each mandrel and die the
angular slots 70 (see particularly Figs. 4, 6 and 22), which slots are of the same
shape on the plane of the die as is the segmental shape of the wrapper blank 28,
so that when one of these slots is brought to position opposite the pocket 29 and
the blauk 28 is pushed by the slide bar 33 into said slut, this slot acts to precisely
centre and lengthwise adjust the blank under one of the mandrels. Before the
mandrel head is thus brought opposite the said blank pocket the mandrel is raised
above its die as shown in Fig. 6, and after the blank has been inserted in the slot
the mandrel is pushed down into the die as seen in Fig. 4, thus partially or half
circularly shaping the blank around the mandrel. When one of the mandrel
carrying blades 62 is thus pushed down and the upper mandrel brought to engage-
ment with the blank, the mandrel on the other end of this plate is pushed out of
the die, so that whenever the head is rotated to bring one of the slots 70 therein
opposite the blank pocket the mandrel of such slot will be in the desired open
position, or out of its die. This movement of the mandrel carrying slide 62 is at
proper times effected by the depression of the tappet elbow-lever 71 (Figs. 1, 3.
and 4) which is attached to rud 72 bearing arm 73, which at proper time is pushed
to the left-hand by mechanism to be hereinafter described, the said elbow lever
and rod being retracted at proper time by spring 74. In each of the wrapper
shaping dies are two spring actuated plungers 7.5 which compress delicately against
the paper blank and prevent it slipping out of center with the mandrel when the
same is forced into the die.
After one mandrel has descended upon a blank, as seen in Fig. 4, the mandrel
carrying head rotates one quarter turn, thus bringing the half shaped blank to
position directly opposite the final shaping jaws 76, (Fig. 4) which jaws are
separately hinged on shalt 77 and are held during the rotation of the mandrel
head in open position as seen in Fig. 4 by the cams 78 acting upon rolls 79 on the
arms 80 of said jaws, springs 81 being provided whereby the jaws are caused to
close and open in accordance with the movement of said cams. After the mandrel
head has been thus partially rotated and the free edges of the wrapper are brought
to between the jaws 76, the said cams are caused to move and close the jaws upon

page_text: the edges of the blank as seen in Fig. 6, thus finally shaping the blank around the
mandrel and bringing the edges therenf into contact, the two edges projecting
radially from the body of the blank. To ensure these edges being properly closed
together and without deflection one on the other, a blade 82 is caused to move
between such edges just before the jaws close upon the same.
85 is a slide mounted in the main framework of the machine, to which slide is
attached the rack 15 (Figs. 1 and 3), and on the slide is pivotally mounted at 86
(Figs. 1 and 42) the said blade 82 which carries the outwardly-projecting tail
piece 87 that at proper time engages with the fixed cam block 88 and causes the
blade to move to position hetween the edges of the blank as described, Figs. 6
and 11. The shaft 77 of the said jaws 76 is mounted upon this elide and carries
the gear wheel 89 (Figs. 1 and 42) which meshes with the extended gear 90
journalled in the frame of the machine and driven through chain belt 91 from the
shaft 48. This slide is reciprocated through the medium of the link 92, (Figs. 1
and 3) pivotally connected to the cam wheel 94 mounted on the upper end of
shaft 45 after the said jaw 76 has closed upon the edges of the filler, blade 82 is
immediately withdrawn from the edges, see Fig. 4, and then the slide 85 begins to
move along the mandrel toward the left-hand.
Upon the upper jaw 76 is mounted the wrapper edge curler or folder block 95
(Figs. 7-12) which contains the open conical slut 96. As the said jaws move
along the edges of the wrapper, these edges enter this conical slot and are cause
to curl, bend or fold on each other so as to interlock one in the other. When the
slide has nearly reached its limit of left-hand travel, it strikes the arm 73 and by
pulling on rod 72 causes the tappet lever 71 to press down one of the mandrel-
carrying slides 62, as above explained. Rack 15 is also attached to (Fig. 3) and
derives its motion from this slide.
Pivotally supported on this slide 85 (see Figs. 1, 3, 22 and 41) is an arm 97
carrying the crimping wheel 98, this wheel being positioned just behind the
curler 95, Figs. 11 and 12. This crimping wheel is serrated and its serrations or
teeth mesh with corresponding serrations on the face of each of the mandrels,
Fig. 25. This crimping wheel engages the folded seam of the wrapper (Fig. 9)
and by rolling along the same pinches it together, indenting or serrating it so that
it becomes finally fixed or sealed. In order to properly press the crimper against
the paper of the seam, it is desirable to apply considerable pressure to the
crimping wheel, but preferably only after it has engaged the wrapper. 99 is
an arm in form like 97 and supported on the same pivot 100. The arm 97
carries a screw 101 which passes into arm 99 so that the two arms can have slight
motion relatively to each other, a spring 102 being provided and which tends to
cause the arms to separate as shown in Fig. 25 when not otherwise acted upon.
The arm 97 is attached to the spring shackle 103 (Figs. 1 and 41), which in turn
is pivotally connected to the elbow lever 104 pivotally supported on the frame
of the machine and held to contact with the cam 105 by spring 106. At the time
the crimping wheel engages the seam of the wrapper, the said cam acts to com-
press the spring on the shackle and thereby force the two arms 97 and 99 together
(Fig. 22) and throw the pressure of the shackle spring upon the crimping wheel,
so that it will properly compress and indent the folded seam of the wrapper.
After the crimping wheel has run the whole length of the wrapper, the said cam
and its spring act to lift the crimping wheel from off the mandrel and to hold it
in such position while the slide 85 is retracted. At the time that the crimping
wheel starts forward and engages the serrations on the mandrel it is pressed in
contact with the latter only by the tension of the small spring 102 (see Fig. 25),
which insures that the crimping wheel will certainly and accurately come to mesh
with the serrations of the mandrel before the crimping wheel engages the folded
edges of the wrapper. In Fig. 25 the serrations of the crimping wheel and of the
mandrel are shown enlarged to clearly illustrate this action. During the time
that the slide returns, the mandrel is rotated a quarter turn and another partially-
shaped blank is brought to position for being acted on by the seaming mechanism.

page_text: When a mandrel-carrying slide is depressed to force the then upper mandrel
upon a blank and the latter into a shaping die, the opposite mandrel, which is the
one then carrying a completed shell or formed wrapper, is pushed down (Fig. 4)
with the completed wrapper still adhering thereto, so that upon another quarter
turn the shell-carrying mandrel (Fig. 6) will be brought to position where the
shell can be stripped therefrom. The mechanism for effecting this stripping is
shown in Figs. 1, 15, 22, 29 and 41. It consists essentially of a stripping roll 107,
which roll is faced with rubber or some similar material. This roll is pivotally
carried on the cam-operated arm 108, which arm is pivotally supported on shaft 55.
109 represents a belt pulley carried on shaft 55, and 110 is a belt running from
this pulley to the stripper roll 107; 111 being an idle roll adapted to hold the
belt properly tightened. 112 is a cam carried on shaft 48 and adapted to engage
the cam roll 113 on said cam arm, and thereby lift the arm and bring the stripping
roll to contact with the shell or formed wrapper. As the shell is stripped or
drawn from the mandrel it is pushed into a receiving trough 114; the stripping
roll, however, serving to only start the shell from off the mandrel (Fig. 15) and
the pusher finger 115 serving to completely discharge the shell and push it into
the receiving trough. This pusher finger is pivotally mounted on the under side
of the frame of the machine, as seen in Figs. 29 and 41, and is operated at the
proper time by a depending finger 116 on the slide rod 117, said rod being operated
in due time by mechanism to be hereinafter described, the spring 118 serving to
retract the slide rod and pusher finger after a single operation. 61 (Fig. 1)
indicates a wiper, of textile or similar material capable of carrying a small
quantity of lubricant, and located so that, as a mandrel moves from position where
it is stripped of the shell formed thereon, this wiper will come in contact with the
serrated surface of the mandrel and lightly lubricate the same, which ensures
the easy stripping of the shell from the mandrel that may be next formed
thereon.
SHELL STRIPPING, AND STOPPING, MECHANISMS.
119 represents what I term a carrier wheel (see particularly Figs. 1, 13, 28-34
and 42). This wheel is composed of two thin blades or disks mounted upon
shaft 120 directly geared to the shaft 63. In the peripheral edge of the disks
are cut radial sockets 121 and 122, these sockets couforming in general shape to
the sizes of the ends of the cigarette. It is to be noted that the latter sockets
are extended nearer to the axis of the wheel than are the former sockets (seo
particularly Figs. 29 and 31). These sockets are so arranged that as the wheel
rotates one step and comes to rest these sockets register with the ends of the
trough 114 (see Fig. 34) and the ends of the stripped shell project through the
same, so that these sockets upou next movement of the wheel engage the shell
lying in the receiving trough and pick it out from the same preparatory to
carrying the shell to position where it is charged with the tobacco filler. The
variation in the depth of the said sockets causes the cigarette shell to lie in the
wheel in an angular position, that is, the axis of the cigarette is at a slight angle
to the axis of the wheel, Fig. 29. Just beneath the sockets 121 are holes 123
cut through this face of the wheel and only a slight thread of metal 124
(Fig. 34) is left between the sockets and such holes, for reasons to be explained
hereafter.
HOPPER MECHANISM.
Referring to Figs. 43-49, 125 represents the casing of the hopper of the
machine, which hopper is of any suitable form adapting it to receive tobacco in
bulk. Located in the top of this hopper is a filling roll 126, the surface of which
is preferably composed of fine wire teeth, pointing opposite to the direction of
rotation. In the bottom of the hopper is a measuring or feeding roll 127, which
is likewise toothed but preferably more coarsely than is the upper roll, its teeth
being pointed in the direction of its rotation. These rolls turn in the same

page_text: direction as indicated by the arrows, but the upper roll preferably has a somewhat
greater speed than the lower roll and an intermittent motion relatively thereto.
As the lower or feeding roll turns against the mass of tobacco its teeth are filled
with the same, the upper or filling roll acting to compact the tobacco uniformly on
the feeding roll and also acting to brush off and back into the mass of tobacco
any surplus that might otherwise be carried along by the feeding roll. 128 indicates
a stripping roll which rotates at greater surface speed thau has the feeding roll,
and its teeth pass between those of the latter roll. This roll 128 acts to strip the
tobacco from the teeth of the feeding roll and deposit it into a trough 129 and
upon an endless belt 130 lying therein and forming the bottom of the trough,
which belt is carried on pulleys 131 and 132. Lying in this trough is a deflecting
bar 133 so arranged that the downward opening of the trough upon the belt is of
different cross sectional widths (see Figs. 43, 45 and 46) that is, this opening is a
long, regularly narrowing slot for a portion of its length. The purpose of this
deflecting piece, or the necessity for making this opening in the trough and to
the belt of such form is that it is desired to distribute the tobacco upon the belt
in such form as will correspond to the conical shape of the cigarette to be formed;
in other words, it is desired that the tobacco be deposited more thickly at one edge
of the belt than at the other (see Fig. 46).
At the left hand end of the trough (Figs. 39, 44 and 48) are located two
stripping rolls 134, which act to brush the tobacco off the belt and into the
pocket 135, Fig. 39. These two stripping rolls, the lower one working at a
greater speed than the upper one, act to regularly feed the tobacco into the pocket
and at the same time to maintain its arrangement as it is distributed on the belt,
that is, the mass of tobacco in the pocket is thicker at one end than at the other.
At the proper time the side of the pocket, consisting of a pivotally supported and
spring-held flap 136 is opened (see Fig. 38) and the tobacco then in the pocket falls
through the chute 137 into a receiving and compressing chamber 138, it being
understood that the above explained distribution of tobacco is still maintained and
that the amount of tobacco let out from the pocket at one time is the amount
which is required for the filler of a single cigarette. The chute 137 is gradually
contracted as shown in Figs. 44 and 47, for the purpose of ensuring the squaring
of the ends of the bunch of tobacco forming a filler. In other words, the
narrowest breadth of this chute indicates the final length of the cigarette filler.
This contraction is shown at 139, a hand actuated cut-off check 140 being provided
for the purposes of closing the chute, as in case of the machine not being in use,
or it being desired to separately actuate the filler-forming or the shell-forming
mechanisms.
The mechanism which effects these various operations is as follows: Referring
first to Fig. 50, 141 indicates a coned countershaft of the machine on which is the
fast pulley 142 and the loose or idle pulley 143, 144 being a belt shifter held to
driving position by the spring catch 145 which engages the fixed stop 146, and
which is released from such stop by the lengthwise movement of the rod 147, the
spring 148 acting through rod 251 to move the belt shifter over the idle pulley
when the said catch is free of the said stop. The shaft 141 bears the coue 149
which is belted to a reverse cone 150 which is journaled in the hanger arms 151
and is held to tight or belting position by the spring 152 attached to the frame, as
also to an arm 153 (Figs. 43 and 48) fixed to the shaft of the said cone 150. The
belt 154 runs from one cone to the other, and the belt shifter 155 running on the
worm 156 is provided, whereby the relative speed of the cones can be changed at
will, for the purpose of accurately and in proper time feeding the tobacco from the
hopper, that is, for the purpose of insuring that for each paper shell that is made
one conical filler shall be prepared and such shell and such fillers fed to a common
point in the machine where they are inserted the one in the other. On the shaft
of cone 150 is a pinion 157 which meshes with gear wheel 158 and, through
pinion 159 and gear 160, drives the sprocket wheel 161 which is directly belted to
a sprocket wheel 162, the latter wheel carrying the eccentrically mounted pawl 163

page_text: and meshes by a pinion on its axis with gear 164, which gear by a pin:on on its
axis meshes with gear 165, which is on the shaft of the tobacco feeding roll 127.
The pawl 163 engages a toothed wheel 166 on the shaft of the filling roll 126 in
the hopper. The sprocket 162 also drives a belt 167 (Fig. 48) running to a pulley
on the shaft of roll 131 by which the tobacco feeding belt 130 is driven. The
stripping roll 128 bears at one end the pulley 168 which is directly belted to the
countershaft wheel 142 by belt 169, and is also belted by belt 169 to the main
driving wheel 170, through which power is primarily delivered to the machine, as
by belt 171.
It will be noticed by this arrangement that when the belt 169 is shifted onto
the loose pulley the hopper :nechanism will cease to act, but the stripping roll 128
will continue to run at regular speed. This is desirable because, when the machine
has been stopped and is again started, if the stripping roll 128 be also started then
the distribution of tobacco on the belt would be uneven for such time as the
machinery is getting under motion. I provide, therefore, that roll 128 shall be
running practically all the time. It will also be noted that the upper roll 126 is
rotated with a step-by-step motion. The purpose of this is to break up the tobacco
ns it lies in the hopper. If this roll were to rotate continuously, the tendency
would be to work the tobacco into a more or less compact roll or bundle in the
hopper and such roll or hundle would gradually increase and by its revolution tend
to prevent the feeding roll 127 properly seizing and filling with tobacco from the
niass. Giving an interrupted motion to the roll 126, effectually breaks up the
mass in the hopper and prevents the difficulty suggested.
The shaft of the main driving wheel 170 carries a brush roll 172 which acts to
prevent the upper roll 126 carrying tobacco over from one side to the other of the
hopper. The other end of this shaft is connected by belt 173 with the axis of the
lower of the two belt-stripping rulls 134, which two rolls are geared together as
seen in Fig. 48. On the axis of this lower roll is a sprocket wheel sleeve 174
(Fig. 47) carrying a cam 175 which acts upon arm 175" on the axis of the spring
held flap 136 of pocket 135, the sprocket wheel being belted by chain belt 176 to
the beveled gear 177 meshing with the gear 178 on shaft 179, a hanger 180 being
arranged between the shaft of said roll 134 and the shaft of the gear 177 to hold
the same in proper relation. 181 (Fig. 39) is a double cam wheel on shaft 179
which actuates the tobacco compressor 182 pivotally mounted on the parts of the
machine surrounding the compressing chamber 138, and also gives reciprocating
motion to the pocket discharger 183, running in ways 183. At the proper time
after the tobacco has been received in the pocket 138 the compressor goes forward,
compresses the tobacco into a compact bulk (Fig. 40), and immediately thereafter
the clearing plunger rises and presses the tobacco in its compacted form out of this
pocket and into one of the dies of the final compressing die mechanism.
FILLER MOLDING MECHANISM.
This filler shaping and compressing mechanism consists essentially (Figs. 1, 2,
14, 36, 38, 39, 41 and 42) of two horizontally arranged disks or plates 184 and 185,
which plates are fixed to the shaft 186, having reciprocating angular motion
through the crank 187 (Fig. 41) at the lower end thereof, pitman rud 188 and
crank 189 on the wheel 46 on shaft 45. Between these two plates is an inter-
mediate die plate 190 having radial slots therein (Fig. 14) 191, each of which
carries a die bead 192 bearing a friction rull 193 running against the periphery of
the upper or cam plate 184, the edge of which (Figs. I and Fig. 2) constitutes a
cam surface acting to give these die heads radial motion. The face of each of
tbese heads is a die cut to form like the longitudinal half of a conical cigarette
(Figs. 14 and 35), the other portion or non-inovable part of the filler die
consisting of blocks 194 secured to the under face of the intermediate or die plate.
This die plate is held to frictional contact with the upper and lower plates by
frictional blocks 195, so that the relative arrangement of the plates will be
B

page_text: maintained, a dog 196 (Figs. 13 and 41) which is pivotally hung on a fixed part of
the frame, being provided for and engaging a rack 197 on the under side of this
die plate to prevent the same being carried backward when the upper and lower
disks are retracted by the return movement of the main shaft 186.
The dog 198 (Figs. 13 and 42) is secured to the lower plate 185 and engages
the rack 197 on the die plate, so that as the crank shaft 186 is partially rotated all
three plates will he carried together, but upon the return motion of said shaft, this
dog rides backward on the rack and dog 196, engages such rack and prevents the
intermediate plate returning with the other two. By these means the dies are
successively brought to place where they are charged with the tobacco fillers in
partially shaped form and carried on step-by-step. As these disks are rotated
backwardly the roll wheel 193 of a die slide is caused to ride up the cam 199,
(Figs. 1. 2 and 14) on the edge of the upper plate, whereupon the die head 192 is
closed upon its co-aeting die member 194, as in Fig. 38, to press the filler into
final form, and after the die parts are closed the shape of the upper die plate is
such as to hold the dies closed during about three-quarters of the revolutions of
the plate; that is, the middle plate is provided with twelve dies, and eight dies.
are always being held closed, each filler being held in its die for sufficient time for
it to set or its final form become established, at least for so long as is necessary to
remove it from the die and put it into a formed wrapper or shell. When a closed
die carrying a filler has reached a position adjacent where the shell is brought by
wheel 119 (Figs. 1 and 42), it is then directly over the filler receiving trough 200
(see also Figs. 28, 29 and 30). While in this position and as the die disk is
returning from a forward motion (Figs. 1 and 2, and as cam 201 passes back of
the roll 193 on the inovable part of the die, the elbow lever 203 is brought into
action by the operation of cam 204 (Fig. 41) and the dog 205 on said lever is
forced forward and against the cam roll of the die and thereby causes the die to be
opened; at the same time extractor fingers 206 carried on said lever 203 enter
through holes in the stationary die block 194 (Fig. 14) of the die and push the
filler from the die (Fig. 32), into the said trough 200. To insure the removal of
the filler from the die, vertical pusher fingers 207 are provided, these being carried
on the vertical slide arm 208, running in ways 208ª (Figs. 13, 39 and 41) supported
on the frame of the machine, which arm is vertically operated by cam 209 on
shaft 179, this shaft being connected through sprocket wheel 210 and belt 211,
with the driving wheel 212 on shaft 55.
A gear 213 (Figs. 39 and 42) on this shaft 179 meshes with a gear 214 on which
is eccentrically supported, by pin 215, a movable rack 216 having up and down
motion relatively to the fixed rack 217, which rack is located directly beneath the
carrier wheel 119, to catch the finished cigarettes as they drop from this wheel.
The motion of this rack is such that it progresses the cigarette individually step-
by-step along the same, at the same time holding them in proper line, a cigarette
resting in each one of the notches of the rack.
After a die has once been opened, and by its next progressive step, a wiper 218,
(Figs. 13, 14, 35 and 36) is caused to enter the die, whereupon the die is closed by
the action of cam 219 on the die plate, then the wiper is reciprocated, then the die
is ppened and the wiper withdrawn and the open die brought to position to be
again charged with tobacco, cam 220 acting in conjunction with cam 219 to effect
these actions. 221 is a rigid finger carried on the pocket clearer 183. Just
beneath this finger is a spring 222. This finger and this spring extend to a position
(see Fig. 13) where they engage between them a projection 223 on the spring 224,
which carries the wiper 218, this spring being mounted on a slide running in
ways 225 supported on the arm 226 pivoted to the frame of the machine at 227
and having operative engagement with cain 228 on shaft 38. When a die has
been discharged of its filler, its next movement is to position just over the wiper,
then when the pocket clearer 183 goes up to charge a new die with tobacco, the
spring 222 litts the wiper into the then open die. Upon the further movement of
the die carrying disks, the die now holding the wiper is closed, the caan 228 will

page_text: act to give a reciprocating motion to the wiper, then the die is opened and the
wiper permitted to leave the same upon the descent of the pocket clearer 183, the
wiper slide being pushed down by the rigid finger 221. A flexible piece like
the spring 222 is provided, because in case of the die not being in position to
receive the wiper injury might be done to the machine, but with this spring to lift
the wiper, if the die be not open or not in position, the spring will yield and no
injury can result.
Referring now to the mechanism for receiving the formed filler and causing the
same to be inserted in the previously formed shell or wrapper (referring particularly
to Figs. 29-33), 229 represents a plunger operated to push the formed filler into
the formed shell, it being understood that the shell is brought to position to receive
the wrapper or opposite the mouth of the trough 200 especially as seen in Fig. 31.
This plunger is carried on a slide 230, which slide is reciprocated in the guide-
ways 231 (Fig. 1) by the gears 232 and 233, the latter gear being on shaft 234,
which extends to and is geared with, by gear 235, the rack 15. "This slide 230
when it is driven forward for the purposes of causing the plunger 229 (Fig. 31) to
insert a filler into a formed shell, strikes against the end of the slide rod 117 for
the purpose, as already described, of completing the removal of a shell from one
of the mandrels and into the carrying wheel 119.
When the shell-carrying wheel 119 brings a shell to position opposite the
receiving trough 200, as seen in Fig. 29, the shell is to be centered in the opening
of the trough 200, and above the supports of shell in the disks 119, and obviously
it is desired that the opposite or smaller end of the same be also so supported. To
effect this support of the smaller end of the shell, a slide 236 is provided, which is
brought forward to engagement with the smaller end of the shell at the proper
time by the retraction of the slide 230 which carries rod 237, which in proper time
engages by pin 238 with a spring arm 239 on said slide 236. This slide also
carries the cam block 240, over which rides another spring-supported cam
block 241. When the rod 237 retreats or moves to the right-hand it pulls the
slide 236 to position as seen in Fig. 31, the shell being lifted up from its radial
notches in wheel 119, the cam 241 riding up over and onto the flat top face of the
cam block 240, and bearing on such face frictionally holds the slide 236 in the
position to which it has been drawn by the rod 237. When the slide 230 advances,
the formed filler is driven into the shell, and as the filler becomes well seated in
the shell and just before its ends register with the ends of the shell, the left hand
end of the rod 237 strikes against the head 242 (Fig. 33) on the slide 236 and
causes this slide to retreat. For a small portion of the retreat movement of this
slide the now completed cigarette is pushed with the slide so that its larger end
clears or is removed from the conical opening in the receiver trough 200. When
this larger end is fully free of the receiver trough 200, the slide 236 has moved to
such a distance that the spring cam 241 comes in contact with the beveled edge of
the cam block 240, whereupon the spring block asserts itself under the stress of its
spring and snaps or quickly pulls or jerks back the slide 236 to position practically
as seen in Fig. 29, thus dropping the cigarette into otches of wheel 115 and free
to be carried by the same to the delivering rack 216 (Fig. 39 and 42), along which
it is moved until dropped off the end of the same.
It is essential to provide that the machine shall be stoppel in case a shell fail to
be brought into position to be charged with a filler; and also in case a filler be not
brought to a shell. In other words, it is desirable that in case of any improper
timing of the actions of the machine, or irregular service of the shell to the filler,
or filler to the shell, the machine will be stopped, so that the proper timing of the
various parts of the machine can be brought into harmony. To accomplish this
result, the essential element thereto is the presence in the disks of the wheel 119 of
the holes 123, and the location of that portion of this wheel 124 which supports
the small end of the cigarette at a higher level or above the corresponding
supporting part of the opposite disk which holls the larger end of the cigarette.
Assuming that for some reason the wheel 119 does not present a shell to the

page_text: opening of the carrier 200, then when a filler is pushed from the carrier and there
being no shell for it to enter, the smaller end of the same will fall into one of the
holes 123 as shown in outline dotted lines in Fig. 33, and this will stop the machine
by the action of the mechanism which will be now explained. And in similar
manner if a shell should he present and the filler be not presented, the machine
will be caused to stop.
243 is what I term. a feeler or finger. It is a delicately supported lever
extending to the position of the shell when being charge! (Figs. 13, 16, 29 and 42)
and is pivotally supported on a fixed part of the machine, and bears a dog 244,
which dog normally is just out of the path of a projecting arm 245 secured to the
underneath plate 185 of the filler-forming mechanism. The axis rod 246 (Fig. 13)
of this finger abuts against the end of the rod 147 which bears at its other end
against the spring catch 145 of the belt shitter 144. Whenever a charged shell is
present in the wheel 119 and under this feeler, the latter is held elevated as shown
in Figs. 16 and 19, and the backward motion of the filler die mechanism can be
effected without striking the dog 244 on the feeler. If, however, a filled shell be
absent when the filler mechanism makes one of its forward step movements, then
the finger will be free to drop and its lug 244 will fall into the path of the notch 247
(Fig. 18) in the periphery of the arm 245 on the filler die mechanism, whereupon
the next forward movement of the latter mechanism will cause the finger axis 246
to be pushed against the rod 147, and the spring catch 145 on the belt shifter will
be released from engagement with the block 146, and thereupon the belt 169 will
be shifted from the fixed wheel 142 upon the idle wheel 143 and the machine will be
stopped.
For the purpose of stopping the wrapper manipulating part of the machine, a
coupling 248 (Fig. 13) is mounted on shaft 55, to the actuating handle 249 of
which coupling is attached a slide bar 250 which extends to the same position as
is the inner end of the rod 251 of the belt shifter 144 of the driving wheel 142.
This bar 250 is frictionally held to such position as it may be adjusted by the
spring plunger 252 (Fig. 44), the handle 253 being provided whereby the
coupling 248 may be actuated by the operator when on the side of the machine
opposite such coupling. A handle 254 ou rod 251 is also provided whereby to
move the belt shifter from over wheel 143 to over wheel 142 and thereby bring
the spring catch 145 into engaging contact with its block 146.
All these various elements of the whole machine are so proportioned and adjusted
and speeded relatively that the manufacture of cigarettes from beginning to enl is
carried on by successive steps; the tobacco being fed in at one point of the
machine and gradually progressed until it is in the form of a compacted filler, the
paper constituting the wrapper being cut, shaped and seamed, and the finished
wrapper or shell being brought to position opposite the filler, the filler inserted in
the wrapper and the finished cigarette delivered from the machine.
