Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester.
both in the County of Lancaster, 118, New Street, Birmingham, in the County
of Warwick, and 322, High Holborn, in the County of Middlesex, Civil Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention has for its object an arrangement of mechanical parts for
enabling the closing of one of the ends of cigarette paper tubes to be effected
mechanically before said tubes are filled.
This arrangement, which may be applied to all machines employed for making
cigarettes or merely tubes, is characterised by the combination with a carriage
carrying a hollow spindle or sleeve provided with a plug and sliding on a fixed and
solid rod carrying the tube, of an arrangement of levers each pivotting on a fixed
point and adapted by means of a rotary movement which is transmitted to them
by a suitable lever to produce the bending and folding over of the end of the
paper tube over the end of said plug.
The apparatus is essentially composed of a carriage formed of two bars con-
nected by cross pieces and actuated by a cam and lever imparting to it a speed
approximately equal to that of the tube under formation.
The carriage has:-
::.
1st. Scissors or shears which divide the continuous tube into lengths suitable
for the manufacture of cigarettes, which shears are themselves actuated by a
lever and cam.
2ndly. A series of levers pivotted on a single ring forming one of the ends of a
box in which the levers are mounted, said levers being actuated by slots or oval
shaped holes formed in the ends of each of them and by levers and a cam.
It is the said ring-mounted levers which by, approaching the centre after the
tube has been cut off, bend over the end of the tube and fold it over a movable
spindle which will now be described.
It is essential for a good formation of the closed end of the tube, that the end of
the spindle must serve as a point of support for the folding over, and in order
that the tubes may be cleanly cut off it is also necessary that this same end shall
stand at a suitable distance from the shears.
In order to realise this double object the tube forming spindle is divided into
two parts, viz., a fixed rod and a movable casing or sleeve formed of a tube sliding
with slight friction 'on the said rod and carrying at its end a plug forming a point
of support. This movable sleeve or casing which is actuated by a cam operating
levers engaging a stud on the sleeve moves away from or approaches the closing
arrangement and stays with it during the necessary time, pressing on the ring-
mounted levers which belong to the carriage it being of course understood that
this movement is produced only when the tube has been cut off.
The working of the apparatus is as follows:--
A tube of paper shaped in the ordinary manner and supported by the fixed rod.

page_text: is cut in lengths by the shears, and this done the movable sleeve provided with
its plug slides along said rod under the action of the levers and cam in order to
afford support to the end of the paper tube which is to be closed, then at this
moment the ring-mounted levers come into action producing the closing of the
tube by bending over and regularly folding down the end of said tube and pressing
it on the plug. The tube is thus formed and is carried away in the, ordinary
manner.
The forms, dimensions, proportions, and accessory, parts may of course be
varied and any suitable materials may be employed for their construction without
departing from the scope of the invention.

I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester,
both in the County of Lancaster, 118, New Street, Birmingham, in the County
of Warwick, and 322, High Holborn, in the County of Middlesex, Civil 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 has for its object an arrangement of mechanical parts for
enabling the closing of one of the ends of cigarette paper tubes to be effected
mechanically before said tubes are filled.
This arrangement, which may be applied to all machines employed for making
cigarettes or merely tubes, is characterised by the combination with a carriage
carrying a hollow spindle or sleeve provided with a plug and sliding on a fixed and
solid rod carrying the tube, of an arrangement of levers each pivotting on a fixed
point and adapted by means of a rotary movement which is transmitted to them
by a suitable lever to produce the bending and folding over of the end of the
paper tube over the end of said plug.
In the accompanying drawings,
Figure 1 is a longitudinal sectional elevation on the line Z Z of Figures 2 and 3
of this mechanical arrangement;
Figure 2 is a plan view of same;
r
Figure 3, an end view of the same arrangement (left hand side of Figure 1);
Figure 4, a transverse section of the main part serving for closing the tube,
such section being on the line X X of Figure 1.
The apparatus is essentially composed of a carriage formed of two bars 1 con-
nected by cross pieces 2 and actuated by a cam 3 and lever 4 imparting to it a
speed approximately equal to that of the tube under formation.
The carriage has:-
1st. Scissors or shears 5 which divide the continuous tube into lengths suitable
for the manufacture of cigarettes, which shears are themselves actuated by a
lover 6 and cam 7.
2nd. A series of levers 8 to 13 pivoted on a single ring 14 forming one of the

page_text: ends of a box in which the levers are mounted, said levers being actuated by slots
or oval shaped holes formed in the ends of each of them and by levers 15 and 16
and a cam 17.
It is the said ring-mounted levers 8 to 13 which, by approaching the centre
after the tube has been cut off, bend over the end of the tube and fold it over a
movable spindle which will now be described.
It is essential for a good formation of the closed end of the tube, that the end of
the spindle must serve as a point of support for the folding over, and in order
that the tubes may be cleanly cut off it is also necessary that this same end shall
stand at a suitable distance from the shears.
In order to realise this double object the tube forming spindle is divided into
two parts, viz. a fixed rod 18 and a movable casing or sleeve 19 formed of a tube
sliding with slight friction on the said rod 18 and carrying at its end a plug 20
forming a point of support. This movable sleeve or casing which is actuated
by a cam 3 operating levers 22 and 23 engaging a stud 21 on the sleeve moves
away from or approaches the closing arrangement and stays with it during the
necessary time, pressing on the ring-mounted levers 8 to 13 which belong to the
carriage, it being of course understood that this movement is produced only
when the tube has been cut off.
The parts WW1 W2 serve for converting the paper strip into the tube but do
not form any part of the present invention, as they are well known, W and W2
being two grips or pincers, one of which W is arranged outside the tube, whilst
the other W is placed inside a mandrel which directs the paper. W is a simple
guide support of both the mandrel and the paper tube.
The working of the apparatus is as follows:-
-
A tube of paper shaped in the ordinary manner by the parts W W1 W2 and
supported by the fixed rod 18, is cut in lengths by the shears and this done the
movable sleeve 19 provided with its plug 20 slides along said rod under the action
of the levers 22 and 23 and cam in order to afford support to the end of the paper
tube which is to be closed, then at this moment the ring-mounted levers 8 to 13-
come into action producing the closing of the tube by bending over and regularly
folding down the end of said tube and pressing it on the plug 20. The tube is
thus formed and is carried away in the ordinary manner.
The forms, dimensions, proportions and accessory parts may of course be
varied and any suitable materials may be employed for their construction without
departing from the scope of the invention.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondents, I declare that what I claim is :-
An arrangement of mechanical parts capable of being applied to all machines
serving for making cigarettes or their tubes characterised by the combination
with a carriage carrying a hollow spindle or sleeve provided with a plug and
sliding on a fixed and solid rod carrying the tube, of an arrangement of levers
or dogs pivotting on a fixed point and adapted by means of a rotary movement
which is transmitted to them by a suitable lever to produce the bending and
folding over of the end of the paper tube over the end of said plug, substantially
as hereinbefore described and shown in the accompanying drawings.
