Improvements in or relating to Cigarette Making Machines.
We, Louis DAVIS and HERMAN HENDRIKS, Merchants, both of 57 and 58,
Broad Street Avenue, in the City of London, do hereby declare the nature of
this invention to be as follows
1
This invention relates to improvements in or relating to cigarette-making
machines and 18 especially applicable to the type of machine known as a con-
tinuous cigarette machine.
The objects of the present invention are to obtain a more efficient and regular
combing and feeding of the tobacco and to provide means whereby the con-
tinuous rod or cigarette may be more expeditiously Bevered into piedetermined
lengths.
The feeding and combing device consists of an upper set of feeding rollers
having plain surfaces, these rolleis co-operating with the feeding band and de-
livering the tobacco to a high speed combing or picking roller having pins
disposed over its surface The said roller disintegrates the tobacco, which falls
into an oscillating hopper moving to and fro over a large picker 1oller 1otating
at a comparatively slow speed The oscillating hopper which is an important
feature of this invention distibutes the tobacco over the picker roller in a
uniform manner, its movement preventing any clogging from taking place. A
plain roller is mounted between the ends of the hopper in such a position
that the roller moves over the large picker roller just out of contact with the
teeth thereof The combined movement of the hopper and action of the roller
accomplish a more uniform distribution and packing of the tobacco upon the
pin surface of the picker 1oller than has heretofore been attained.
The tobacco is further combed and disintegrated by a second high speed
combing or picking roller the pins of which intercalate with the pins upon the
large picker roller, and the tobacco in a finely divided and uniform condition
1s finally delivered on to a travelling band by which it is conveyed to the com-
pressing device
Any suitable means may be employed for oscillating the
hopper, as for instance an eccentric keyed upon the diving shaft operating an
arm projecting from the hopper, through the medium of an eccentie 10d If
desired it may be so aanged that the travel of the hopper is variable and the
position of the roller therein adjustable.
The improved "cut off" or severing mechanism according to this invention
enables a much higher velocity of the knife blade to be obtained than has
hitherto been possible, without necessitating any increase in the space occupied
by the gear. The knife blade is bolted to a spui wheel preferably mounted
above the cigarette delivery aperture, the said spur wheel being of an elliptical
shape and gearing with a similarly shaped driving spur-wheel, or both spur
wheels may be cucular and mounted eccentrically upon then spindles, by this
arrangement the diven spur wheel will have a velocity alternately greater and
less than the dining spur wheel. The spui wheels and knife are so arranged

page_text: that the latter shall perform the "cut off" at the moment the velocity of the
diven spur-wheel reaches its maximum, the knife is thus given a high velocity
and a cleaner cut is accomplished also the danger of buckling the continuous
rod or cigarette is reduced to a minimum

Improvements in or relating to Olgarette Making Machines.
We, LOUIS DAVIS and HERMAN HENDRIKS, Merchants, both of 57 and 58,
Broad Street Avenue, in the City of London, do hereby declare the nature of
this invention and in what manner the same 18 to be performed to be particularly
described and ascertained in and by the following statement -
This invention relates to improvements in or relating to cigarette-making
machines and is especially applicable to the type of machine known as a con-
tinuous cigarette machine.
The objects of the present invention are to obtain a more efficient and regular
combing and feeding of the tobacco and to provide means whereby the con-
tinuous 1od or cigarette may be more expeditiously severed into predetermined
lengths
The feeding and combing device consists of an upper set of feeding 1ollers
having plain surfaces, these rollers co-operating with the feeding band and de-
livering the tobacco to a high speed combing or picking roller having pins
disposed over its surface The said oller disintegrates the tobacco, which falls
into an oscillating hopper moving to and fro over a laige picker roller rotating
at a comparatively slow speed The oscillating hopper which is an important
feature of this invention distributes the tobacco over the picker roller in a
uniform manner, its movement preventing any clogging from taking place
plain oller is mounted between the ends of the hopper in such a position
that the roller moves over the large picker 1oller just out of contact with the
teeth thereof The combined movement of the hopper and action of the 1oller
accomplish a more uniform distibution and packing of the tobacco upon the
pin surface of the picker roller than has heretofore been attained
A
The tobacco 18 further combed and disintegrated by a second high speed
combing or picking roller the pins of which intercalate with the pins upon the
large picker roller, and the tobacco in a finely divided and uniform condition
18 finally delivered on to a travelling band by which it is conveyed to the com-
pressing device Any suitable means may be employed for oscillating the
honner, as for instance an eccentue keyed upon the diving shaft operating an
aim projecting from the hopper, through the medium of an eccentric rod If
desued it may be so arranged that the travel of the hopper 18 variable and the
position of the roller therein adjustable.
The improved cut off" or severing mechanism according to this invention
enables a much higher velocity of the knife blade to be obtained than has
hitherto been possible, without necessitating any increase in the space occupied
by the gear. The knife blade is bolted to a spur wheel preferably mounted
above the cigarette delivery aperture, the said spur wheel being of an elliptical
shape and gearing with a similaily shaped driving spur-wheel, or both spur
wheels may be circular and mounted eccentrically upon the spindles; by this
arrangement the duiven sput wheel will have a velocity alternately greater and
less than the driving spur wheel. The spur wheels and knife are so arranged

page_text: that the latter shall perform the "cut off" at the moment the velocity of the
driven spur-wheel reaches its maximum, the knife is thus given a high velocity
and a cleaner cut is accomplished also the danger of buckling the continuous
1od or cigarette is reduced to a minimum

With reference first to Figures 1 and 2, A 18 the bed plate of the machine
supported on standards A. The various portions of the tobacco disintegrating
and feeding mechanism are mounted in a frame-work A bolted to the bed
plate A. The tobacco is first placed upon a conveyor band B which travels over
pulleva B1 and B2 (Figure 2) The pulley B is furnished with tightening gear
as at B, and is caned upon a platform A3 extending from the top of the
frame A and supported upon standards A10 Jounalled in the frame Ain

evenly as it passes over the end of the conveyor hand B A second plain 1oller C¹
18 Journalled in the frame A³ close to the roller C and the pulley B₁
arranged to rotate in the opposite direction to the pulley B and its function
is to draw the tobacco fiom between the plain ollei C and the conveyor band
B and to deliver it to a combing or picking eller D, which 18 Jounalled in the
fame beneath the pulley B and the roller C₁ This picking 1ollet D 18
arranged to revolve in the same duection as the pulley B¹ but at a much higher
speed, by its action the tobacco is torn into fine shreds and then falls into a
hopper Ein a finely divided or disintegrated condition. The hopper E 18 pivotally
mounted as at E¹ (Figure 2) upon the axle F¹ of a large slow speed picking
1oller F which forms the bottom of the hopper A plain roller F (Figure 2)
18 mounted between the ends of the hopper E so that it is just clear of the pins
or teeth upon the large piching rollei F As will be hereinafter described the
hopper E is caused to recipiocate when the machine is in operation, and the
effect of this reciprocation and the rotation of the picking roller F is to cause the
tobacco to be evenly distributed and packed between the pins of
the latter, the small holler
contubuting to produce this
1esult Beneath the picking roller F 18 a small high speed pick-
ing 01 combing olle G+ arranged 80 that its teeth intercalate with
the teeth upon the slow speed picking roller F This high speed roller G tears
the tobacco from between the teeth of the large roller thereby effecting the
final and complete disintegration of the tobacco, which then falls into a hopper H
and is delivered on to the travelling band J and caned to the cigarette foiming

The gear for operating the various portions of the feeding and disintegrating
mechanism is as follows.-Power is tiansmitted to the main shaft A, which is
supported in brackets A from the bed plate A, by means of a belt As and pulley A
Upon the shaft are fixed a spui pinion K and chain wheels L and M
spur pinion K gears with a spur wheel K' mounted upon a shaft K2 which 18
canned in a bachet AB attached to the frame Aª Upon this shaft K* is a
chain wheel K³ which dives, by means of a chain K and chain wheel K³, R
shaft K journalled in a bracket A secured to the top of the frame A' Upon
the shaft K 18 a bevel wheel K7 geaning with a similar wheel K8 secured to a
shaft K³, and another bevel wheel K upon the other end of the shaft K³.
gears with a bevel wheel K" which is called upon the shaft of the pulley B¹.
Upon the opposite extremity of the axle of the pulley B' a spur pinion (not

page_text: shown
in the drawings) is fixed which communicates motion to the plain
rollers C and C¹ through pinions C and C³ The large picking roller F is diven
from the pulley B₁ by means of a chain B which engages with chain wheels,
one upon the axle of the pulley B¹ and the other upon the axle F¹ of the roller F.
The upper high speed picking 1oller D 18 driven from the main shaft A+ by
means of the chain wheel L, chain L¹. chain wheel L³, gear_wheel L³ and
pinion L, the latter being mounted upon the axle of the roller D. The lower-
most picking roller G is driven from the chain wheel M upon the main shaft A¹
through the chain M, chain wheel M and gear wheels M³ and M
The oscillation of the hopper E is effected by an eccentric N keyed to the
main shaft A, this eccentric operating a 1od N¹ which is coupled to an arm E
attached to the hopper E.
The operation of the tobacco feeding and disintegrating mechanism is as
follows The tobacco having been placed upon the conveyor band B is carried
over the pulley B', and is evenly 1olled and fed to the combing or picking
roller D by means of the plain 1ollers C C¹ The picking 1oller D rotating at
a high speed effects a very fine disintegration of the tobacco which falls into
the oscillating hopper E and is uniformly distributed and evenly packed over
the pin surface of the large slow-speed ioller F, owing to the action of the
hopper E and its roller F. The disintegration of the tobacco 18 completed by
the lower high-speed picking roller G, and the tobacco then falls into the
hopper H and is delivered to the travelling band J
The travelling band J conveys the tobacco to suitable mechanism which com-
presses it and forms it into a continuous papel-covered cigarette. This part
of the machine however forms no part of the piesent invention, and is therefore
not described or illustrated in the drawings

The continuous cigarette 0 (Figure 1) is fed forward by the action of a
travelling tape P, a portion of which is shown in Figure 1, and passes into the
Bevering oi cut off" mechanism. A flared tubular entrance R guides the
continuous cigarette into a tube R¹, which passes through a reciprocating car-
11age R moving upon the bed plate A in undercut guide ways R³ At the
upper part of the carriage R is a spindle S carrying a spur wheel S¹, which 18
free to evolve upon the spindle but is mounted eccentrically thereon
blade S is bolted to the eccentue spur wheel S, and is arranged so that as the
wheel rotates the knife blade S2 passes between the end of the tube R', and
another tube R placed in line with and in close proximity to the tube R', thus
cutting off a predetermined length from the continuous cigarette.
A knife
Coupled to the carriage R 18 a short eccentric rod or link R which is operated
by an eccentric R7 which is carried upon a shaft R8 in a bearing R upon the
bed plate A The shaft RB 18 provided with a bevel wheel Rio, which gears
with and is diven from another bevel wheel T carried upon a shaft T¹ (Figure 4)
in a bearing T³ This shaft T is driven by a gear wheel T3 (Figure 3) mounted
upon it
The eccentric spur wheel S receives its motion from another eccentric spur
wheel S3, which is mounted with freedom to move laterally upon a shaft S,
Arms S are pivotted round the shaft S on either side of the eccentric wheel 8',
and their other extremities encircle the shaft S on either side of the eccentric
wheel S in order that the two wheels S¹ and S³ may be kept in gear when
the carriage Reciprocates The shaft 8 carries a gear wheel So, which engages
with a gear wheel T caned upon a shaft T³ This shaft T3 caries another
gea wheel T which is duiven through an intermediate wheel T7 from a gear
wheel T upon the main shaft A The gear wheel 14 engages with and drives
the gear wheel T3 upon the shaft T. The intermediate wheel T' is mounted
in a quadrant T which is pivotted about the shaft T so that diving wheels T
of varying diameters may be employed in order to alter the length of the
cigarette which 18 cut off at each revolution of the wheel S¹ The quadrant T⁹
18 plotted and may be fixed in any desired position by a nut and washer.

page_text: The parts are so set that the carriage R commences its forward movement in
the same direction and at the same speed as the continuous cigarette at the
moment that the knife blade S commences its cut, so that during the severing
operation the knite blade and the cigarette 1od which it is cutting move forward
together.
"
The eccentric mounting of the spur wheels S¹ and S³ produces a much faster
cut off" than could be obtained with spur wheels of the same dimensions
mounted concentrically. The eccentric wheels are ananged so that just before
the knife blade S commences to cut, that point upon the periphery of the spur
wheel S which is nearest to its centie 18 in gear with the wheel S', the point
on this latter wheel in gear being necessarily that at the greatest distance from
its centre. Thus the knife blade S18 travelling at its fastest rate during the
cutting operation and a clean cut results, the danger of buckling the cigarette
being reduced to a minimum.
The cigarettes after having been severed fall on to
convenient receptacle.
