ABSTRACT OF THE DISCLOSURE
A cigarette making machine is disclosed. The machine
comprises a housing, a tobacco chamber located in the housing, an
opening in the housing for introducing a batch of tobacco in such
chamber, a press plate movable in the chamber for compressing the batch
of tobacco into a substantially cylindrical body, a cam plate pivotally
mounted on the housing and engaging the press plate, an actuating member
connected to such cam plate for operating the cam plate, a tube supporting
means aligned and communicating with the chamber, a plunger slidably
mounted in the housing and extending through the chamber, and link means
interconnecting the plunger to the actuating member and operated by the
cam plate. Rotation of the actuating member first causes the press plate
to compress the batch of tobacco and then advances the plunger through
the chamber to expel the tobacco body into a cigarette tube mounted on
the tube supporting means.

43
This invention relates to a cigarette making machine.
~ACKGRUUND Of THE INUENTION
; '
Cigarette making machines of the type adapt0d to compress
a batch of tobacco into a substantially cylindrical body and to transfer
the tobacco body into a prefabricated cigarette tube have been known for
years. However, the existing machines are normally actuated by means
of a crank arm which extends substantially out of the machine and by a
complicated mechanism which adds tD the cost Df the machine.
_
- SUMMARY OF THE IN~ENTION
It is therefore the object of the present invention to
provide a cigarette making machine which is compact and includes a minimum
number of operating parts, thus reducing the manufacturing cost.
The cigarette making machine, in accordance with the
invention, comprises a housing, a tobacco chamber located in such housing,
an opening in the housing for introducing a batch of tobacco in the chamber,
a press plate movable in the chamber for compressing the batch of tobacco
into a substantially cylindrical body, a cam plate pivotally mounted on
the housing and engaging the press plate, an actuating member connected to
the cam plate for operating the cam plate, tube supporting means aligned
and communicating with the chamber~ a plungHr slidably rnounted in the
housing and ex~ending through the chamber~ and link means intarconnecting
the plunger to the actuating member and operated by such cam plate, whereby
rotatian of the actuating member first causes the press plate to compress
the batch of tobacco and then advances the plunger through the chamber to
expel the tobacco body into a cigarette tube mounted on the cigarette tube
supporting means.
In a preferred embodiment of the invention, the link means
includes two arms pivotally interconnected at one end and having their
opposite end pivotally connected to the axis of said cam and to the
plunger, respectively. An abutment means extends from the cam and engages
one of such arms to pivot such one arm around the shaft of the cam and so
move the plunger.

SHORT DESCRIPTIûN OF THE DRAWINGS
The inventlon will now be disclosed, by way of example~
with reference to the accompanying drawings in which:
Figure 1 illustrates a p~rspective view of a cigarstte
making machine in acoordance with the invention;
Figure 2 illustrates a top view,with the cover removed,
of the cigarette making machine shown in Figure l;

5 showingthe operation of the cigarette making machine.
DESCRIPTION OF A PREFERRED EM80~IMENT
, . .
Referring to the drawings, there is shown an embodiment
20 o~ a cigarette making machine comprising a houslng 10 made oP any suitaole
material~such as metal or plastic~ having an opening 12 communicating
with a chamber 14 integral with the housing. Opening 12 is for introducing
shredde~tobacco into the chamber 14. A press plate 16 is slidably mounted
in the chamber 14 for compressing the tobacco. The ~ace 18 o~ the housing
and the ~ece 20 of the press plate are semi-circular in construction so
. as to compress the batch of tobacco into a substantially cylindrical body.
: A cam plate 22 mountad on a shaft 24 is rotatably mounted on the housing
Por actuating the press plate against the biasing action of springs 26
interconnecting the press plate to the housing~ An actuating member 28 is
: 30 mounted on shaft 24 for operating the cam plate 22.
A tube.supporting means 30 is mounted on the side of the
housing and communicates with the chamber 14 in alignment with the face 18

thereof for a reason which will become obuious later on in the description.
An arm 52 is pivotally mounted on the housing and provided with a head
34 engaging tube supporting means 30 for holding cigarette tubes on the
tube supporting means under the action of a spring 36 interconnecting
the other end of the arm 32 to the housing. As shown in Figure 5, a slot
38 i8 provided in the press plate 16 and a pin 40 is located at the end
of arm 32 for holding head 34 away from the tube supporting means when the
press plate is retracted 80 as to permit insertion of a cigarette tube
onto the cigarette tube supporting means.
- 10 A plunger 42 is slidably mounted in a cauity 44 molded into
the housing. Plunger 42 has a Qemi-circular portion 46 extending through
the ohamber slong the wall 18. The plunger is in alignment with the
cigarette tube supporting means for a reason which will become obvious
later on in the description.
A link including arms 48 and 50 is provided for operating
the plunger 38. Arms 48 and 50 are pivotally interconnected at 52 and
their opposite ends are pivotally connected, respectively, to the shaft 24
of the cam plate 22 and to the plunger 42 at pivot point 54. An sbutment
means 56 is provided on the cam plate 22 for engaging arm 48 and opereting
, . . .
the same again~t the action of a spring sa interoonnecting arm 4~ and the
housing. A alot 60 is prouided at the bottom of cavity 44 for sllow~ng
sliding of the plunger pivot 54 along the oavity.
In operation, the chamber 14 is first filled with shredded
tobacco and a cigarette tube inserted over the tube supporting means.
The aotuating member 28 i8 then rotated in the direction of arrow A in
~igure 7. During the first 90 rotation of the actuating member, the
press plate 16 is moved by cam 22 to oompress the shredded tobacco between
semi-circular faces 18 and 20 to form a cylindrical body of tobacco.
,~
Upon continued rotation of the actuating member 28, as sh wn in Figure ~,
o t~e abutment member 56 contacts the arm 48 to move arm 50 and plunger 42
~?
so as to push the plunger through ths chamber 14 and out the opening in
the tube supporting means 30. This operation will eject the tobacco body
out of the chamber and into the cigarette tube. Upon rotation of the
~; .

-- actuati~g member 28 back to its original position, the press plate 16
will be withdrawn by springs 26 and pin 40 of the lever 32 will ride
in slot 38 of the press plate to move head 34 from tube retaining means
30 to free the cigarette tube.
Although the invention has been disclosed with reference :-
to a preferr`ed embodiment, it is to be understood that modifications
of such embodiment are envisaged. For example, the tobacco chamber 14
and the cavity 44 for the plunger need not be integral with the housing.
In addition, other types of link means suitable for operation by the
