This invention is for improvements in or re
lating to. cigarette making or like machines, such
for example as tobacco packaging machines, and
refers more particularly to a method of and
5 means for feeding tobacco to such machines.
It is an object of the present invention to pro
vide a method of, and‘ means for, feeding to
bacco whereby the individual weights of ciga
rettes produced by a cigarette making machine
10 is greatly improved.
The tobacco feeding apparatus referred to
particles of tobacco contained in the stream are
mixed with the lighter particles of an adjacent
stream.

According to one form of the present inven
tion, there is provided a method of feeding to
bacco to a cigarette making or tobacco packaging
machine by showering particles of tobacco to
wards a surface moving continuously in one di
rection, the particles forming a shower thewidth
of which extends lengthwise of the moving sur
face, sub-dividing the shower along its width,‘
forming the sub-divided portions’into streams,
diverting the direction of fall of the streams and
45 delivering the streams to the moving surface
from points disposed above and remote there
from by a distance such that the combined widths
of the streams as they engage the moving sur
face or the tobacco contained thereon is greater
O than the total width of the shower. The streams
may‘ also be delivered to the moving surface with
a component of movement in the direction of
movement of the surface.v
The streams may be delivered to the surface

In another form the invention consists in a
cigarette made in accordance with the method

‘or by the machine just described;
In a still further form, the invention consists
of tobacco packaged‘ in accordance ‘with the
method or by the machine just described. >
The invention will ‘be more particularly de
scribed by way of example with reference to the
accompanying drawings, in which:-—
Figure 1 shows diagrammatically a sectional
elevation of tobacco feeding apparatus con
structed in accordance with the invention.
Figure 2 is a sectional end elevationlooking 50
in the direction indicated in Figure 1.
Figure 3, is a perspective view showing a por
tion.of Figure 1.
_
'
Figure 4 is a diagrammaticplaniview of a por
tiOn of Figure 1, showing the manner in which

streams of tobacco are delivered to a moving sur
face.
Like references refer to like parts throughout
the speci?cation and drawings.
Referring to the drawings, tobacco is fed by
any suitable known means from a hopper (not
shown), and is deposited upon the surface of a
distributor roller I, from which it is picked by’a~
picker roller 2, and formed into a shower which
10 is directed towards a surface 3 moving continu
ously in one direction. In the example given the
moving surface 3 comprises a web of cigarette
paper moving on the bottom of a' trough 4 which
may, if desired, form the moving surface, so that
15 it has a U-shaped cross-section, as illustrated
more clearly in Figures 2 and 3.
It is to be understood that the terms‘ “moving
surface” and “travelling web” as employed herein
are not limited to a web of cigarette paper.
20 Obviously the surface or web may be comprised
by other means, for example an endless tape or
band, ‘or other conventional form of conveyor.
Above the moving surface 3 and in the path of
‘the shower of tobacco there is disposed a number
ly perpendicularly from the ends of the bent
ends 6.
From the foregoing description and by refer—
ence to Figure 4, it will be seen that the sum
total of the lengths ‘l of the‘ stream will be greater "a
than the overall, width of the shower from which
streams were formed. It follows, therefore, that
the tobacco taken from the shower is spread over
a greater surface than has hitherto been the
custom, and further, that due to the arrangement
of the ends 6 of the plates or vanes, the light and
heavy particles of tobacco from the shower are
more evenly mixed than is the case when using
the known types of tobacco feeding apparatus.
Although for the purposes of illustration the
lengths ‘l are shown in Figure 4 as being isolated,
it will be understood that the streams are nor
mally delivered to the tobacco which is carried
by the moving surface and that the streams only
the direction of movement of the moving surface
have the appearance shown in Figure 4 if the 20
view is taken at a point just above the moving
surface. The purpose of Figure 4 is merely to
show the manner in which the streams fall from
the ends of the plates or vanes and in which the
light and heavy particles are mixed. For in 25
stance, each of the rows of tobacco particles
3, as shown clearly in Figure 1. The plates or
shown in this ?gure represents diagrammatically
'vanes 5 are arranged to sub-divide the shower
along its width, and to form the sub-divided
30 portions into streams which slide down the sur
the manner in which tobacco is projecting on
the moving surface at a given instant by each
face of the plates or vanes and are delivered
from the ends 6 of the plates or vanes, which are
component of movement in the direction of move
ment of the surface by reason of the forward in
clination of the vanes and a component of move
ment transverse to the direction of movement of
the moving surface by reason of the fact that the
lower ends of the vanes are bent or set askew, so
25 of plates or vanes 5 which are inclined towards
bent in the direction in which the conveyor is
moving, as shown clearly in Figure 1. The por
tions 6 are bentso that they are substantially
parallel with the moving surface, and the stream
of tobacco, as it leaves the ends of the plates or
vanes therefore moves in a substantially horizon
tal plane.

The portions 6 of the plates or vanes 5 are ar
ranged above the moving surface 3 and remote
from the surface by a distance such that the
tobacco’ in falling on to the moving surface or on
to the tobacco carried thereby, is caused to
45 spread lengthwise along the surface.
The distance by which the ends 6 of the plates
or‘ vanes 5 are remote from the moving surface
is su?iciently great that the length '1 of the mov
ing surface over which the tobacco is spread is
50
greater than the width 8 of the shower from
which the stream was formed. By this means,
tobacco from the shower tends to be more evenly
spread on the surface of the moving surface 3
than is the case when the tobacco is-showered
55 on to the moving surface by any of the previously
known
methods.

The plates or vanes 5 may be of semi-circular
or trough-like construction, as shown in Figure 3,
to facilitate the forming of the streams, and the
.60 ends 6 of the plates or'vanes may be set askew
or bent as shown in Figure 3,’so that the streams
being delivered from adjacent plates or vanes do
not impinge on'ea‘ch other, but the light portions
of tobacco 9 from one stream are delivered onto
of the vanes, the tobacco particles being given a 30
that the tobacco particles are in effect projected
diagonally across the moving surface.
If desired, the moving surface 3 may be moved
in a direction opposite to that indicated in Figure 40
l, and in this way the tobacco delivered to“ the
moving surface is given a component of move
ment in a direction which is opposed to the direc
tion of movement of the moving surface.
It is found when running cigarette making ma 45
chines at speeds producing cigarettes of 70 m/m
length at the rate of over 1000 per minute, that
the tobacco showered on to the moving surface
tends to bounce upwardly from the moving sur
face owing to the increased speed at which the 50
tobacco is thrown down by the picker, thus dis
turbing the formation of the tobacco on the mov
ing surface.
By directing the tobacco towards
the moving surface in the manner just described,
that is to say, by the use of means which alters 55
the direction of downward movement of the
tobacco and imparts a component of movement
thereto in a direction more nearly horizontal, as
by the bending of the lower ends of the. vanes,
the tendency for the tobacco to bounce is re
duced, and therefore, there is less disturbance
of the formation of the tobacco on the moving
surface.
With the arrangement just described the plates
65 an area of the conveyor adjacent in a transverse
or vanes may, if desired, be arranged above the
direction to that of the heavy portions ll] of
tobacco from the adjacent stream, so that when
moving surface at a sufficient height and formed
and staggered as above described to spread and
mix the particles of tobacco.
the tobacco is formed into a rod, the light por
tions 9 become mixed with the heavy portions in.
70
It will be appreciated that the heavier por
tions Ill of a stream will be carried a greater dis
tance in a forward direction as the stream leaves
theends 6 of theplates or vanes than will-the

What is claimed is:
1. A method of feeding tobacco to a cigarette
making or tobacco packaging machine which
comprises showering particles of tobacco towards
30 an endless moving surface in a shower the width
of which extends lengthwise of the moving sur
face, subdividing the shower along its width and
giving to the falling tobacco of each subdivided
portion a horizontal component of movement,
35 and .also a lateral movement in a direction the
comprising a generally trough-shaped vane pro
vided with a laterally directed lower end portion
approaching closely to a horizontal plane and
spaced above the traveling web to an extent suf
?cient to permit substantial increase in the width 30
of the stream of tobacco between the point of
discharge from' the vane and the point of im
pingement on the web.
5. A method of feeding tobacco to a cigarette
making or tobacco packaging machine which com 35
projection of which on the plane of the moving
prises discharging particles of tobacco down
surface is transverse to the direction of move
. wardly toward an endless moving surface in a
ment of the latter, the horizontal movement be
ing imparted to the subdivided portions at a
40 sufficient height above the moving surface to en
sure that the tobacco in each subdivided portion
is spread to a greater width than the original
width of said portion at a point of subdivision of
the shower and whereby due to the lateral move
45 ment imparted to the tobacco the heavier par
ticles of tobacco contained in a subdivided por
tion are together with the lighter particles of an
adjacent subdivided portion delivered onto the
'50
the web, said‘ elements being interposed in the
path of the‘ discharged tobacco and'rinclined
downwardly and forwardly in the direction of
movement of the web, said elements being so
moving surface adjacent to‘ each other in a
transverse direction.
2. In an arrangement for spreading tobacco
showered to a moving tobacco receiving surface
on a cigarette making machine or a tobacco pack
aging machine, the combination with means for
55 showering the tobacco toward the‘ said surface,
of a device for subdividing the shower into widths
extending lengthwise of said moving surface and
imparting to the tobacco in each subdivision a
horizontal component of movement and also a
lateral movement in a direction the projection of
which on the plane of the moving surface is trans
verse to the direction of movement of the latter,
said device being so constructed that theposition
at which the said horizontal movement is im
65 parted to the tobacco is at a sufficient height
above the said moving surface to spread the to
bacco of each subdivision lengthwise of said sur
face to a greater width than the original width
of the subdivision, whereby the said lateral
70 movement causes light and heavy particles from
shower of which the width extends lengthwise of
the moving surface, subdividing the shower along
its width and imparting to the falling tobacco of 40
each subdivided portion a movement having a
component in the direction of movement of said
surface and a lateral component in a direction
transverse to» the direction of movement of said
‘surface, the said movement being imparted to 45
the subdivided portions at a sufficient height
above the moving surface to ensure that the to
bacco in each subdivided portion is spread to a
greater width than the original width of said
portion at a point of subdivision of the shower, 50
whereby due to the lateral movement imparted '
to the tobacco the heavier particles of tobacco
contained in a subdivided portion are together
with the lighter particles of an adjacent sub
divided portion delivered onto laterally adjacent
areas of the moving surface.

6. In apparatus for use in a cigarette making
machine, the combination with means support
ing a travelling web for movement in a pre
determined path, of means for discharging tobac 60
co downwardly toward said web in a shower
of which the width extends generally lengthwise
of the moving surface, and means for subdividing
the shower along its width into separate portions
and. discharging each of such portions onto said
web from a point disposed above the latter in a
