I EUGÈNE ALFRED DURAND of Paris in the Republic of France Engineer do
hereby declare the nature of this Invention to be as follows:—
This Invention relates to a rotating compressing or moulding device wherein by
means of an alternating or reciprocating circular motion the tobacco or other material
that is to be made up in the form of cigarettes is compressed uniformnly in all
directions in such a manner as to ensure the regular or uniform filling of the mould
and consequently a regular and uniform shape of the rolls or cylinders of tobacco or
the like which are then pushed by a plunger into a tube previously prepared for their
reception. An apparatus constructed according to this invention is provided with an
external case of cylindrical form closed at its extremities and supported on a suitable
stand.
The tobacco is compressed between to opposite edges of two segments of a hollow
cylinder or tube fitted inside the case. One of these segments is fixed to the case the
other being capable of being rotated by a lever. Two opposite edges of the segments
are hollowed so as to form two halves of a circular mould. A cylinder capable of
rotating is arranged concentrically within the two segments and presents a transverse
slot or opening in which there is provided a sliding block having its edges rounded so
as to correspond with or form continuations of the periphery of the cylinder. A rod
passes longitudinally through this block and has two protruding extremities acted on
by springs at each side of the apparatus. The central cylinder can be rotated by
means of a lever acting on a pawl and ratchet arrangement.
The tobacco is spread in a thin layer on an endless apron working on rollers
operated by means of a connecting rod attached to the moulding or feeding devices
and working a pawl and ratchet. A compressing roller is placed above the feed
roller.
The tube of paper for the reception of the cylinder of tobacco is supported by
fingers or clamping devices at one side of the apparatus and the rod or plunger by

page_text: which the cylinder of tobacco is pushed out of the mould into the said tube is operated
by a rack and pinion or otherwise from the opposite side. This rod may be operated
directly by hand or by releasing a spring which causes it to shoot out the tobacco
more expeditiously and effectually. When motion is imparted to the feeding
apron a certain quantity of tobacco is introduced into the opening in the contral
cylinder and at the side of the sliding block which does not entirely fill the said
opening.
The central cylinder is then caused to describe half a revolution so as to carry this
tobacco round to the recess or cavity formed on the opposite side of the said cylinder
between the hollow edges of the two segments forming the halves of the mould. The
rod hereinbefore describe as passing longitudinally through the block in the central
cylinder is arranged excentrically to the axis of the latter so that as the cylinder
revolves the block is pushed over to the other side and expels the tobacco
forcing it into the moulding cavity at the same time forming a space at the
opposite side of the sliding block for the reception of a fresh charge of
tobacco.
The moveable half of the mould is then operated by the lever so as to bring the
edges of the cylindrical segments together and compress the tobacco into the form of
a cylinder or roll which is then pushed out of the mould into the tube of paper. The
cigarette thus formed is then removed and replaced by an empty tube and the operation
is repented.
The tobacco may be placed directly in the moulding cavity by hand in which case
the feed apron and sliding block are dispensed with.
The apparatus may be used either as an independent machine or as part of a
complete machino provided with mechanism for making the paper tubes.

page_text: I, EUGÈNE ALFRED DURAND of Paris in the Republic of France 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 :—
This Invention relates to a rotating compressing or moulding device wherein by
means of an alternating or reciprocating circular motion the tobacco or other material
that is to be made up in the form of cigarettes is compressed uniformly in all directions
in such a manner as to ensure the rogular or uniform filling of the moulding chamber
and consequently a regular and uniform shape of the rolls or Cylinders of tobacco or
the like which are then pushed by a plunger into a paper tube previously prepared for
their reception. The apparatus which is provided with stationary and moveable
working parts of circular or Cylindrical shape presents the advantage of admitting of
being made almost entirely upon the lathe whereby considerable economy is effected
in the manufacture. The circular motion enables it to work with great ease and
sinoothness and admits of its being effectually lubricated without risk of bringing the
tobacco into contact with the oil.
And in order that the said Invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the several
figures on the annexed sheets of drawings the same letters of reference indicating
corresponding parts in all the figures.
Figures 1 and 2 of the accompanying drawings represent respectively end and side
elevations of a self feeding machine constructed according to this Invention and
figure 3 is a vertical section of the same the section being taken along the line 1-2
figure 1.
Figure 4 is a front or end elevation of a hand feed machine working on the same
principle and figure 5 is a transverse section of the same along the line 3-4 figure 4.
Figure 6 illustrates a modification of the ejector hereinafter described.
The apparatus illustrated in figures 1, 2 and 3 is provided with an external case E of
cylindrical form closed at its extremities by two plates and supported on a suitable
stand B. This case contains two segments TT' Figure 3 of a hollow Cylinder which
form a divided mould The lower segment T¹ is fixed to the case E and the upper
segment T is provided with a lover handle L whereby it can be rotated to a limited
extent The edges of the segments TT are hollowed as indicated on the right hand
side of figure 3 so as to form two halves of a circular mould when brought together
The space enclosed by these segments is occupied by a solid Cylinder C capable of
being rotated by means of a lever O and having a transverse slot or opening passing
through its centre in which works a sliding block R the edges of which are rounded
so as to correspond with or form continuations of the periphery of the Cylinder C. A
rod X passes fongitudinally through this block and has two protruding extremities
acted on by springs Z figures 1 and 2 at each side of the apparatus The lever O acts

page_text: upon the contral Cylinder C by means of a pawl and ratchet arrangement V as
indicated in figure 2 The tobacco is spread in a layer of suitable and uniform thick-
ness on an endless apron V₁ working on rollers rotated by means of a connecting rod
or link P operated by the moulding segment T and working a pawl and ratchet P¹ by
means of a lever P' A compressing roller V is placed above the roller at the feed
end of the apron and is geared with this roller so as to slightly compress the tobacco
and force it to enter the apparatus.
The tube of paper for the reception of the compressed cylinder of tobacco formed
by the action of the segments TT is supported by a clamping devices at H figure 1.
and the rod or plunger I by which the Cylinder of tobacco is ejected or pushed out of
the mould into the said tube (indicated by dotted lines at H' figure 1) is operated by a
rack and pinion arrangement at S. the action of which will be readily understood by
referring to the drawing (figure 1).
In place of this rack and pinion the ejector or plunger I may be operated directly
by hand being arranged to work in suitable guides as indicated at MN figure 4 or
preferably by a spring arrangement (figure 6) which causes it to shoot out the tobacco
more expeditiously and is less liable to cause the tobacco to stick in or choke up the
tube than the other arrangements with a slow and continuous compressing action
especially when the tobacco is damp.
When the lever handle L being in the position indicated in figure 3 is pushed over
to the right the feeding apron V introduces a certain quantity of tobacco into the
opening in the central Cylinder C and at the side of the sliding block R which does
not entirely fill up the said opening. The Cylinder C is then caused to describe half
a revolution so as to carry this tobacco round to the recess or cavity formed on the
opposite side of the said Cylinder between the hollow edges of the two Cylindrical
Segments TT forming the halves of the mould The rod X hereinbefore described as
passing longitudinally through the block R is arranged excentrically to the axis of the
Cylinder Cso that as the Cylinder revolves the block is pushed over to the other sido
of the opening by the action of the spring Z and expells the tobacco therefrom forcing
it into the moulding cavity at the same time forming a space at the opposite side of
the sliding block for the reception of a fresh charge of tobacco.
The moveable half T of the mould is then again operated by the lever L so as to
bring the edges of the cylindrical Sogmonts TT together and compress the tobacco
into the form of a cylinder or roll which is then pushed out of the mould into the tube
of paper Hand the same movement of the lever L introduces a fresh charge into
the Cylinder C-The Cigarette thus formed is then removed and replaced by an empty
tube and the operation is repeated for the following Cigarettes.
According to the arrangement illustrated in figures 4 and 5 the tobacco is placed
directly in the moulding cavity by hand through an opening a b in the upper part of
the case E in which case the feed apron V and sliding block R are dispensed with the 4
tobacco being simply compressed and moulded between the moveable segment T and
the fixed segment T The tobacco is then pushed into the paper tube by the action of
the pusher MN.
When the spring arrangement illustrated in figure 6 is employed the roll of tobacco
is pushed out by a rod or ejector M¹ N¹ operated by a knob or button O¹ acted on by a 4
compressed spring R' shewn in dotted lines When the knob O₁ is moved to the left
the spring Ris compressed and locked in this position so that when released it propels
the pusher sharply to the right and drives the roll of tobacco out of the mould and
into the tube.
This improved rotary moulding apparatus can be employed independently as herein- 5
before described with tubes prepared before hand or it may form part of a machine
arranged to make the tubes as well as to fill them.
This rotary moulding apparatus is applicable to the manufacture of all kinds of
chemical or medicinal or other Cigarettes as well as Cigarettes of tobacco. The
structural details and materials employed in the construction of the apparatus may 5
evidently be varied without affecting the principle of the Invention.
