I, HERBERT HENRY LEECH LEWIS trading as Lewis and Lewis of Cambridge
Works, Cambridge Heath Road, in the County of Middlesex, Engineer, do hereby
declare the nature of this invention to be as follows :-
In this machine the tobacco is placed loosely in a vertical hopper with glass sides;
at the bottom of the hopper are a pair of feed rollers of large diameter with projecting
teeth which are so formed as to readily release the tobacco at the desired time; these
rollers revolve in opposite directions and are fixed with a space between them less
than that between the two sides of the hopper in order to partially compress the
tobacco as it is drawn through; below each of these rollers is placed another roller
of smaller diameter and formed with grooves corresponding to the teeth on the larger
rollers, into which grooves these teeth pass; these rollers revolve in the same direction
as the larger rollers; the spindles of both sets of rollers work in bearings which may
be made adjustable if desired so that the space between the rollers can be varied
and made equal to the thickness of the strip of tobacco that is required to be
produced.
The rollers and hopper are carried by a fixed framework, a shear blade is fixed to
the lower part of this framework a little behind the edge of one of the lower feed
rollers; a sliding frame kept in position by guides works backwards and forwards on
the lower face of the fixed framework which carries the rollers and hopper. A knife
blade is fixed at a suitable angle to the sliding frame and caused to pass with the
frame across the face of and in contact with the shear blade fixed to the framework
thus causing a shearing action.
This sliding frame is worked backwards and forwards by a connecting rod driven
by a crank on the main or driving shaft of the machine.
Motion is given to the feed rollers as follows; on the shaft or spindle of one of the
lower feed rollers a ratchet wheel is fixed, a lever provided with a pawl is mounted
loosely on the same shaft or spindle and the pawl engages in the ratchet wheel. To
one end of this lever is attached a link which is formed with a slot at one end thereof
which receives a projecting pin carried by one end of the moving frame but as the

page_text: slot in the link is shorter than the traverse of the sliding frame a part of the
movement of the frame is communicated at each end of its traverse to the slotted
link, the lever, and the pawl and ratchet wheel. By these means an intermittent
rotary motion is given to the feed roller upon the shaft or spindle of which the ratchet
wheel is fixed. Motion is communicated to the opposite small feed roller by a pair of
toothed wheels of equal diameter and motion is given to the larger upper rollers by
a pinion on the shaft or spindle of one of the lower rollers gearing into a wheel on
the shaft or spindle of one of the opposite and upper rollers. The proportion of these
wheels is regulated by the diameters of the upper and lower rollers and the relative
distance apart of the two pairs of rollers.
The whole of the above tobacco feeding and cutting mechanism is carried by a
cross bracket resting on and fixed to the side frames of the machine.
Beneath the tobacco feeding and cutting mechanism and on the bed plate of the
machine is fixed a swinging tray the shaft or spindle of which is carried by brackets
fixed to the bed plate. At one end of this shaft or spindle is a crank lever whereby
a forward motion is given to the tray by a cam connected to the sliding knife frame
through a suitable arrangement of levers and links: As this tray is required to
return quickly to its normal position I effect this movement by the following means.
The said cam acts upon a roller which has a lateral movement and is kept in its
normal position by means of a spring, a small incline or wedge on the cam moves
this roller sideways and clear of the cam at the end of its stroke and so that the
tray may spring back quickly a spring of any suitable kind being employed for this
purpose.
The object of the swinging frame is to feed the separate charges of tobacco into
and form a pocket or bight in the band hereinafter referred to.
A drum is employed which is formed of two side wheels each having a boss and
fitted on to the same shaft or spindle, in the rim of each of these wheels are drilled
an equal number of small holes. A small roller with its ends made to fit the holes in
each wheel is placed with one end on each wheel. These rollers are made larger
than the cigarette and the side wheels are fixed to the shaft or spindle so that the
rollers will revolve freely between them. This arrangement of drum together with
the band hereinafter referred to constitutes the cigarette former and can be arranged
to form one or more cigarettes at each revolution of the drum. When required to
form two cigarettes at two opposite points a wide space is left between the rollers at
such points and in each of these spaces a travelling roller is inserted; this roller is
carried by two arms one at each end thereof which fit onto the drum shaft or spindle
by which means the roller is free to revolve on its own axis and travel circumferentially
of the drum through the space left between the other rollers. In order to give this
motion backwards and forwards a shaft or spindle passes through a hole formed in
arms of each wheel of the drum at each space, that is to say there is one shaft or
spindle to each travelling roller; each spindle at one end carries a crank and at the
other a disc, the crank and the disc are each respectively connected to the levers which
carry the travelling roller and as partial rotary motion is given to this spindle the
levers are moved from side to side of the space and the travelling roller moves across
the space left between the other rollers. A cam of suitable shape is fixed to the bed
plate or other fixed portions of the machine and on the face of the disc fixed on the
end of each shaft or spindle is a small roller, which when the drum is caused to
revolve runs on the edge of this fixed cam and follows its outline.
The shaft or spindle which carries this drum revolves in bearings attached to the bed
plate of the machine.
A band of silk or other suitable material passes over this drum each end of which
band is secured to a bar extending across the drum, each bar is carried by a radial
arm working on the drum, shaft or spindle and a projecting portion thereof forms a
lever. To this portion of each bar is attached a connecting rod suitably guided and
carrying a truck or roller and each roller works against a cam fixed on the upper or
driving shaft these cams through the connecting rods and radial arms give the
requisite lift to the bars to which the ends of the band are attached; and as a spring

page_text: or weight is empleyed to pull them down, the requisite motion is thus given to either
end of the band.
Upon the bed plate of the machine are fixed two side frames upon which are fixed
the bearings which carry the driving shaft or spindle. The driving shaft or spindle
is formed with a crank to which is attached the connecting rod that works the knife
frame backwards and forwards.
:
At one end of the driving shaft is fixed a double cam and at one end of the drum
shaft or spindle is fixed a disc or wheel having four notches in the periphery thereof
and a pawl carried by an arm or arms engages in these notches. A lever mounted on
a fulcrum pin fixed to the side frame carries a roller at one end which works against
the double cam on the driving shaft and at the other end such lever is provided with
a slot which engages with a pin on the pawl arm or arms. A spring attached to the
lever keeps it up to the cam and the cam gives it a forward movement the proportion
of the lever and cam is such that at each half revolution of the driving shaft
the pawl engages in one of the four notches of the disc or wheel and moves
it round a fourth of a revolution moving the spindle and the drum attached thereto
with it.
The following is a description of the mechanism for feeding cutting and pasting
the paper.
The paper which is in a continuous roll is mounted upon a spindle which is carried
in suitable bearings on the bed plate of the machine being free to revolve as the
paper is drawn or wound off.
A small platform set at a suitable angle is fitted at the upper edge with a roller and
at the lower edge with a fixed shear blade; intermediate of these parts are fixed two
feed rollers one below the table and one above; the roller below the table has
a step by step rotary motion given to it and the top roller acts as a pressure
roller.
At one side of this platform is fixed a radial arm which moves in the arc of a circle;
to the end of this arm and parallel to its axis is fixed a shear blade which by the
rotary motion of the arm passes down in front of the fixed shear blade and in
contact with it forming a pair of shears which will cut off the paper passed between
them.
The radial arm is mounted on and firmly fixed to the end of a shaft or spindle at
the other end of which is a crank, this crank is connected to another crank on the
driving shaft of the machine by a connecting rod. The crank on the driving shaft
of the machine is shorter than that on the shaft or spindle of the radial arm so
that while the one revolves and makes a complete circle the other only describes
the arc of a circle.
On the shaft or spindle forming the axis of the radial arm is a loosely mounted
toothed wheel which takes into a pinion on the shaft or spindle of the bottom feed
roller. On the same shaft or spindle is fixed an arm or a disc which carries a pawl,
this pawl engages in the teeth of the pinion before referred to, which is made wide
enough to receive both the wheel and the pawl.
By this arrangement the teeth of the pinion catch the pawl and drive it round
when moving in one direction and leave it stationary when moving in the opposite
direction; the feed roller which is on the same shaft or spindle as the pawl disc or
arm receives same motion and to prevent the feed roller running back a ratchet
wheel is fixed to the shaft or spindle and a fixed pawl prevents it moving except in
one direction.
As the moveable shear blade travels some distance past the fixed shear blade and
the forward feed movement takes place during the upward movement of the arm it
is necessary that the feed should not commence until the moving knife has risen
above the fixed knife; the toothed wheel on the spindle of the radial arm is therefore
not rigidly fixed to it but is driven by a projection on the shaft or spindle which
moves between two stops on the wheel so that the wheel remains stationary
while the projection on the axle travels from one stop on the wheel to the other.
Above the paper feeding and cutting mechanism described above, is fixed a

page_text: receptacle for the paste or other adhesive material, the bottom of this is perforated to
allow the paste to pass through and spread on the under surface thereof. On the
radial arm a little above the knife blade is fixed a roller brush or other suitable con-
trivance which at the extreme upward movement of the radial arm passes under and
touches the bottom of the above mentioned receptacle and by contact therewith
receives on its surface a small portion of the adhesive material which it transfers to
the edge of the paper on the downward stroke of the radial arm. The paper feeding,
cutting and pasting mechanism is carried by a bracket which rests on and is fixed
to the side frames of the machine.
Between the paper feeding and cutting mechanism described above and the drum
of the machine is fixed a moveable paper clip which is carried by arms hinged to
brackets screwed to the bed plate of the machine, it moves backwards and forwards
between the paper cutting knife and the rolling band, it is held back by a spring and
is moved forward by a roller on the radial arm, working against a
cam fixed to
the paper clip; this cam is shaped so as to give the requisite amount of movement
to the paper clip.
The upper jaw of the clip which works on centres carried by the lower part
thereof is held down by a spring and is opened when required to release the paper
by the action of the same roller that gives the forward movement; this roller at a
certain point is moved sideways by a wedge shaped projection on the cam fixed to
the paper clip and comes in contact with a cam lever attached to the upper clip and
this opens it at the time required.

page_text: I, HERBERT HENRY LEECH LEWIS trading as Lewis and Lewis of Cambridge
Works, Cambridge Heath Road, in the County of Middlesex, Engineer, do hereby
declare the nature of this invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
My invention is illustrated in the accompanying drawings in which Figures 1 and 2
are two opposite side elevations, Figure 3 is a plan with some of the parts removed,
Figure 4 is a longitudinal section and Figures 5, 6, 7, 8 and 9 are detail views of a
cigarette forming machine constructed according to my invention and Figure 10 is
a longitudinal section of a cigarette forming machine and Figure 11 is a longitudinal
section of parts thereof showing a slight modification.
In all the figures like parts are indicated by similar letters of reference.
I will first describe the arrangement represented at Figures 1 to 7.
In this machine the tobacco is placed loosely in a vertical hopper a slightly
larger at the bottom than at the top and which is formed with glass sides to
enable the contents thereof to be readily seen; at the bottom of this hopper are
a pair of feed rollers b, b, of large diameter with projecting teeth which are
formed, as shown, of such a shape as to readily release the tobacco at the desired
time; these rollers b, b, revolve in opposite directions and are fixed with a spacė
between them less than that between the two sides of the hopper a in order to
partially compress the tobacco as it is drawn through; below each of these
rollers is placed another roller c of smaller diameter and formed with grooves
corresponding to the teeth on the rollers b, b into which grooves these teeth
pass; these rollers c, c revolve in the same directions as the rollers b, b; the
spindles of both sets of rollers work in bearings, one or both of each pair of
which may be made adjustable if required so that the space between the rollers
can be varied and made equal to the thickness of the strip of tobacco that is
required to be produced.
The hopper a and rollers b, b, c, c are carried by a fixed frame work A¹; a
shear blade d is fixed to the lower part of this framework a little behind the
edge of one of the lower feed rollers c, c; a sliding frame e kept in position by
guides works backwards and forwards on the lower edge of the fixed framework A₁,
a knife blade e¹ is fixed to the sliding frame e and caused to pass with such frame
across the face of and in contact with the fixed shear blade d, thus causing a shearing
action.
This sliding frame e is worked backwards and forwards by a connecting rod e
driven by a crank f' on the main or driving shaft of the machine.
Motion is given to the feed rollers b, b, c, c, as follows; on the shaft or spindle e
of one of the lower feed rollers c, c, a ratchet wheel is fixed, a lever c³ provided
with a pawl c is mounted loosely on the same shaft or spindle and the pawl o
engages in the ratchet wheel c'. To one end of this lever c³ is attached one end of

page_text: a link which is formed with a slot at its other end which receives a projecting
pin e carried by one end of the moving frame e, but as the slot in the link c
is shorter than the traverse of the sliding frame e, a part of the movement of
the frame e is communicated at each end of its traverse to the slotted link c³,
lever c, pawl c and ratchet wheel c². By these means an intermittent rotary
motion is given to the feed roller c upon the shaft or spindle of which the
ratchet wheel c² is fixed.
Motion is communicated to the opposite small feed roller c by a pair of toothed
wheels c, c, of equal diameter and motion is given to the larger upper rollers b, b,
by a pinion e' on the shaft or spindle of one of the lower rollers c, c, gearing into
a toothed wheel 61 on the shaft or spindle of the opposite upper roller b. The
proportion of these wheels is regulated by the diameter of the upper and lower
rollers b, c, and the relative distance apart of the two pairs of rollers.
Motion is given from one roller 6 to the other by a pair of toothed wheels 6³
fixed on the spindles thereof.
The whole of the above tobacco feeding and cutting mechanism is carried by
a cross bracket A² resting on and fixed to the side frames A, A, of the machine.
Beneath the tobacco feeding and cutting mechanism and on the bed plate A³
of the machine is fixed a swinging tray g, the shaft or spindle 91 of which is
carried by brackets A fixed to the bed plate A³. At one end of this shaft or
spindle is a crank lever g² whereby a forward motion is given to the tray g
by a cam g³ connected to the sliding knife frame e and acting upon a lever g
mounted on a fixed axis g' and connected by a link g to the crank lever g³.
As this tray g is required to return quickly to its normal position 1 effect this
movement by the following means. The said cam 93 acts upon a roller
axis of which is mounted in a boss or bearing carried by the lever
capability of lateral motion therein and such roller g is kept in its normal
position by means of a spring 98; a small incline or wedge 9' on the cam moves
this roller g sideways and clear of the cam 93 at the end of its stroke and in
order that the tray 9 may spring back quickly, a spring (not shown) of any
suitable kind is employed for this purpose as will be well understood.
the
with
The object of the swinging frame or tray g is to form a pocket or bight in the
band and at the same time to feed the separate charges of tobacco into such
pocket or bight.
A drum is employed which is formed of two side wheels each having a boss h¹
and fixed on the same shaft or spindle 2; in the rim of each of these wheels h
are drilled an equal number of small holes. A small roller ³ with its ends made
to fit the holes in each wheel h is placed with one end in each wheel. These
rollers are made longer than the cigarette and the side wheels h are fixed to
the shaft or spindle 2 so that the rollers A³ will revolve freely between them.
This arrangement of drum together with the band hereinafter referred to constitute
the cigarette former and can be arranged to form one or more cigarettes at each
revolution of the drum. When required to form two cigarettes at two opposite
points as shown in the drawings a wide space h* is left between the rollers ³
at such points and in each of these spaces a travelling roller is inserted; this
roller is carried by two arms one at each end thereof which fit on to the
drum shaft or spindle 2 by which means the roller is free to revolve on its
own axis and travel circumferentially of the drum through the wide space * left
between the rollers h³.
In order to give this motion backwards and forwards a shaft or spindle h passes
through a hole formed in arms of each wheel of the drum adjacent to each
spaco h, that is to say, there is one shaft or spindle h to each travelling roller /*;
each spindle at one end carries a crank 7, and at the other a disc "; the
'crank and the disc .h are connected to the arms or levers 7, through the
links and as a partial rotary motion is given to this spindle the arms or
Levers are moved from side to side of the space and the travelling roller h*
moves across the wide space * left between the rollers h³.

page_text: A cam 10 of suitable shape is fixed to the bed plate A³ or other fixed portion of
the machine; on the face of the disc ³ is a small roller which when the drum
is caused to revolve runs on the edge of the fixed cam ho and follows its outline.
A spring connected at its ends to the discs / keeps the trucks or pulleys h¹¹ up
to the cam 10.
12
The shaft or spindle carrying the drum revolves in bearings A* attached to the
bed plate A3 of the machine.
A band of silk or other suitable material passes over this drum each end of
which band is secured in any suitable manner to a bar extending across the drum ;
each bar is carried by a radial arm or lever working on the drum shaft or
spindle h³ to a portion of each arm or lever i projecting on the opposite side of the
shaft or spindle is attached a connecting rod which is forked at its upper end
(see Figure 2) and is guided in its motions by such fork travelling on the shaft or
spindle; this connecting rod carries a truck or roller and each roller works
against a cam fixed on the upper or driving shaft f, these cams, through the
connecting rods 3 and radial arms or levers, give the requisite lift to the bars i¹
to which the ends of the band i are attached and as a spring or weight (not shown)
acting on each cordis employed to pull them down, the required motion is thus
given to either end of the band i.
At one end of the driving shaft f is fixed a double cam j and at one end of the
drum shaft or spindle h² is fixed a disc or wheel & having four notches in the periphery
thereof and a pawl carried by an arm or arms engages in these notches.
A lever mounted on a fulcrum pin fixed to the side frame A carries a roller
at one end, which works against the double cam ; on the driving shaft f, and at the
other end such lever is provided with a slot which engages with a pin /* on the
pawl arm or arms 1.
A spring (not shown) attached to the lever keeps it up to the cam j and the cam
gives it a forward movement; the proportion of the said lever and cam is such that
at each half revolution of the driving shaft the pawl engages in one of the four
notches of the disc or wheel k and moves it round one fourth of a revolution moving
the spindle and the drum attached thereto with it.
The mechanism for feeding, cutting and pasting the paper is constructed and."
operated as follows:―
The paper which is in a continuous roll is mounted upon a spindle m which is
carried in suitable bearings A' on the bed plate A³ of the machine; such spindle
being free to revolve as the paper is drawn or wound off.
A small table or platform n set at a suitable angle is fitted at the upper edge with
a roller n' and at the lower edge with a fixed shear blade n²; intermediate of these
two parts are mounted two feed rollers o, o, one below the table n and one above;
the roller o below the table n has an intermittent rotary motion given to it and the
top roller o acts as a pressure roller.
At one side of the table or platform n is mounted a radial arm p which moves in
the arc of a circle; to the end of this arm and parallel to its axis is fixed a shear.
blade p¹ which by the rotary motion of the arm passes down in front of the fixed
shear blade n and in contact with it thus forming a pair of shears which will cut.
off the paper passed between them.
The radial arm p is mounted on and firmly fixed to the end of a shaft or spindle p
at the other end of which is a crank p³; this crank is connected to another crank pt.
on the driving shaft f by a connecting rod p³.
The crank on the driving shaft is shorter than the crank p³ so that while the one
revolves and makes a complete circle the other only describes the arc of a circle.
On the shaft or spindle p³ forming the axis of the radial arm is a toothed wheel p
which takes into a pinion o¹ loosely mounted on the shaft or spindle o' of the bottom
feed roller o. On the same shaft or spindle o is fixed an arm or a disc o³ which
carries a pawl o; this pawl engages in the teeth of the pinion o¹ before referred to,
which is made wide enough to receive both the toothed wheel p and the pawl o'. By
this arrangement the teeth of the pinion o catch the pawl of and drive it round when

page_text: moving in one direction and leave it stationary when moving in the opposite direction;
the feed roller o which is on the same shaft or spindle o² as the pawl, disc or arm o³
receives the same motion and to prevent the feed roller o running back a ratchet
wheel of which is fixed to the shaft or spindle o' and a fixed pawl (not shown) prevent
it moving except in one direction.
As the moveable shear blade p¹ travels some distance past the fixed shear blade n³
and the forward feed movement takes place during the upward movement of the
arm p, it is necessary that the feed of the paper should not commence until the
moving knife p¹ has risen above the fixed knife n'; the toothed wheel p on the
spindle p² of the radial arm p is therefore not rigidly fixed to it but is driven by a
projection p' on the boss of the arm p or on the shaft or spindle p' which moves
between stops p³ on the wheel pa so that the said wheel remains stationary while the
projection p on the shaft or spindle p³ travels from one stop on the wheel to the
other.
Above the paper feeding and cutting mechanism above described is fixed a
receptacle q for the paste or other adhesive material; in this receptacle is mounted
loosely on a pin a paste or cement conducting roller q', which supplies paste or cement
from the receptacle q, to the endless band r; this band is mounted on rollers 1
carried by a frame and receives an intermittent forward motion in the following
manner.
On the axis of the roller r¹ is a grooved pulley around which passes an endless
band or gut which also passes around guide pulleys to and around a grooved
driving wheel or pulley * fixed to the axis o2 of the lower feed roller o. By these
means the endless band r is moved forward simultaneously with the feed rollers o and
thus presents a fresh surface of cement or paste to the carrying roller s which supplies
the paste or cement to the edge of the cut cigarette paper. This roller s is mounted
in a frame s carried by the radial arın p and on the axis of the roller s is a ratchet
wheel which acts in combination with a pawl s³ so that it can revolve in one
direction only; by these means as the radial arm p rises to its extreme upward
position the roller's passes under and touches the lower part of the endless band r
slightly revolving as it passes in contact therewith and thereby receives on its surface
a small portion of the cement or paste which it transfers to the edge of the cut
cigarette paper on the downward stroke of the radial arm p.
After the carrying rollers has received its supply of cement or paste from the
endless band and at the commencement of its descent the roller t comes into
contact with the incline 78 fixed to the frame which latter is supported on a centre
with capability of slight motion thereon by which means the endless band is with
the frame raised sufficiently to allow the rollers to pass the endless band without
touching it but on the return or rising motion of the roller s the roller is shunted
end wise by the bevel edge 10 of the frame so as to miss the said frame and allow
the rollers to come into contact with the band r.
Between the paper feeding and cutting mechanism described above and the drum
of the machine is fixed a moveable paper clip t, t' which is carried by arins t² hinged
to brackets A screwed to the bed plate A of the machine; it moves backwards and
forwards between the paper cutting knife n² and the cigarette rolling band i; it is
held back by a spring to and is moved forward by a roller t on the radial arm p
working against a cam fixed to the paper clip; this cam to is shaped so as to give
the requisite amount of movement to the paper clip.
The upper jaw t of the clip which works on centres carried by the arms t² is held
down by a spring t* and is opened when required to release the paper by the action
of the roller t that gives the forward movement to the clip; this roller t at a certain
point is moved sideways by a wedge shaped projection to on the cam to fixed to the
paper clip and comes in contact with an arm or lever t' which acts upon a lever +8
fixed to the bar carrying the upper jaw t; by shunting the roller t from the cam t³
on to the arm or lever, the spring is allowed to act on the arm t' whereby the
paper clip is withdrawn from the drum and by the action of the arm t upon the
lever to the said clip is at the same time opened.

page_text: In the modification represented at Figures 10 and 11 instead of employing a tray g
to receive the separate charges of tobacco from the feeding mechanism and convey it
into the pocket or bight in the rolling band i formed by the front edge of such tray g,
I employ an endless band 910 to receive the separate charges of tobacco and to carry
them forward to the pocket or bight in the rolling band whilst below such endless
band go I employ a plate all carried and operated in a similar manner to the tray g
to form such pocket or bight in the rolling band i.
The endless band 910 passes round two rollers g" and is moved by a cord g¹³ attached
at one end to the sliding knife frame e and having a weight g" at the other, this cord
passes round a drum on the spindle of one of the rollers g and as the sliding knife
frame travels backwards the cord 9" moves the roller spindle in one direction and
the weight g¹ on the return of the knife frame e pulls the cord g¹³ in the opposite
direction; a ratchet wheel on the roller spindle and a fixed pawl (not shown) prevent
the roller spindle being rotated in a backward direction on the return motion of the
cord g¹³. All the other parts of the machine are similar to those described with
respect to Figures 1 to 9.
The operation of the machine is as follows:-
Tobacco supported on a table B, see Figure 1, is placed as required into the
hopper a and is fed through the lower end of the hopper by the feed rollers b, b, c, c.
Separate charges of tobacco, cach sufficient for a cigarette, are there cut off by means
of the shears d, e¹, which charges are received on to the tray g and conveyed into a
bight or pocket formed in the rolling band i and the cigarette completed in the
following manner.
The bar at the right of figure 4 is raised by the action of the cam ³ in connection
with it; this slackens the band, as shown in Figure 4; the tray g is moved forward
and in its motion forms a bight or pocket in the band i and at the same time drops
the said charge of tobacco into it; this tray then springs back and the drum h, h³
commences to revolve; during the first portion of its movement the bar at the left
of figure 4 follows the same motion, the opposite bar remaining stationary, thus
increasing the depth of the bight or pocket and securing the retention of the tobacco
therein; at the same time the roller in contact with the said bight or pocket is
moved circumferentially of the drum across the space h* and closes the mouth of the
bight or pocket, the left bar is then held stationary; while this bar i¹ is thus held
stationary the drum h, h³, continues to revolve and by so doing tightens the band i
round the charge of tobacco; the bar at the left now commences to fall and the
opposite bar commences to rise while the drum completes one quarter revolution;
this gives a rolling motion to the enclosed charge of tobacco. When the drum has
completed this quarter revolution and the tobacco has arrived at the position shewn
at Figure 6, the mouth or aperture of the bight or pocket is opposite the paper
feeding arrangement and the drum remains stationary for a time; the paper,
previously cut and cemented or pasted, is then brought forward by the clip t, t' and
introduced into this aperture, an upward movement is then given to the bar at the
right and a corresponding downward movement to the opposite bar i¹; this move-
ment being communicated to the band causes the charge of tobacco to revolve in the
bight or pocket and draws the paper in and rolls it round the tobacco, the cigarette
is then completed. A further movement of the drum aided by the cam h¹º causes the
moveable roller to travel backwards across the space * thereby opening the mouth
of the bight or pocket and releasing the cigarette, which falls into a suitable receiver;
the space in which the cigarette has been formed is now opposite the position it
started from and the opposite space h* is in that position ready to receive a charge of
tobacco which passes through the same operations as those above described. The
movements of the band can be modified to suit different sizes of cigarettes; the other
parts of the machine are also adjustable for the same purpose.
When using the modification shown at Figures 10 and 11 the charges of tobacco
are received on to the endless band gs and delivered by it into the bight or pocke
formed in the band i by means of the plate gl as before described; the other parts
and motions of the machine are as described with reference to Figures 1 to 9.
