PROVISIONAL SPECIFICATION.
Machine for the Filling of Cigarette Paper Tubes with Tobacco.
I, LOUIS JEAN BAPTISTE DUPLOYER of 115 Gaisford Street, Kentish Town
London, Mechanical Engineer do hereby declare the nature of this invention to
be as follows
My invention has for object the filling of cigarette paper tubes with tobacco.
For this purpose, I find that the tobacco must be compressed first and decom-
pressed immediately after, so that it can slide easily from the place where it has
been compressed into the paper tube.
On a suitable frame, I fix at the back a hand lever moving vertically on an axle.
On this hand lever are adapted two rods moving on pivots and connected with a
sliding block moving horizontally towards a fixed block in the edge of which is cut
a groove to form a part of the receptacle where the tobacco is compressed. The
sliding block has the same groove on its edge nearest the fixed block and forms the
other part of the receptacle for tobacco.
By pulling down the lever the rods connected to it and to the sliding block,
bring this block towards the fixed block, thus compressing the tobacco placed
previously in the opening. The compression is made till the rods reach an
horizontal line with the sliding block, the decompression begins as soon as the run
of the lever bring the heads of the rods a little under the horizontal line. A rest
fixed on the frame stops the course of the lever and gives mechanically the right
amount of decompression.
On one side of the compressor, (the left side preferably) is fixed a funnel through
which passes the tobacco, and on the outside of which is placed one end of the tube
of paper.
On the other side of the compressor is another hand lever moving horizontally
and carrying with it in a slide a metallic rod which bas to push the tobacco held in
the compressor through the funnel into the paper tube.
During the moving of this horizontal lever the paper tube is held on the tube
of the funnel by a spring clip which release the paper only when the horizontal
lever touches the end of its course, and forces the spring clip to open, by means of
a connecting rod.
To help the paper tubes to enter the end of the funnel, I provide a small
cylindrical metallic cone which opens and rounds the paper tube so it enters easily
into the top of the funnel.
The tobacco coming from the compressor into the tube throws the metallic cone
through and out of the tube and the tobacco takes its place.
I provide at the same time at the end of the funnel a rest on which fall the
cigarette made, and which also receives the metallic cone thrown off the tube.

I LOUIS JEAN BAPTISTE DUPLOYER, 55 Rue de Belleville, Paris, in the
Republic of France, 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 has for object the filling of cigarette paper tubes with tobacco.
For this purpose I find that the tobacco must be compressed first and decompressed
immediately after so that it can slide easily from the place where it has been
compressed into the paper tube.
On a suitable frame I fix at the back a hand lever moving vertically on an axle.
On this hand lever are adapted two rods moving on pivots and connected with a
sliding block moving horizontally towards a fixed block in the edge of which is
cut a groove to form a part of the receptacle, when the tobacco is compressed;
the sliding block has the same groove on its edge nearest the fixed block and forms
the other part of the receptacle for the tobacco.
By pulling down the lever, the rods connected to it and to the sliding block;
bring this block towards the fixed block and compress the tobacco placed previously
in the opening. The compression is made till the rods are in a horizontal line with
the sliding block, the decompression begins as soon as the run of the lever brings the.
heads of the rods under the horizontal line. A rest, fixed on the frame, stops,
the course of the lever and gives mechanically the right amount of decompression.
On one side of the block compressor (the left side preferably) is fixed a funnel
through which passes the tobacco and on the nozzle of which is placed one end of
the tube of paper. On the other side of the compressor is another hand lever
moving horizontally and carrying with itself in a slide a metallic rod which has to
push the tobacco held in the compressor through the funnel into the paper tube.
During the moving of this horizontal lever, the paper tube is held properly on the
tube of the funnel by a spring clip which releases the paper only when the horizontal
lever touches the end of its course and forces open the spring clip by means of a
connecting rod.
To help the paper tube to enter the end of the funnel, I provide a small
cylindrical metallic cone which opens and rounds the paper tube; so that it enters
easily into the nozzle of the funnel.
The tobacco coming from the compressor into the tube throws the metallic cone
through and off the tube and the tobacco takes its place.
I provide at the same time at the end of the funnel a rest on which fall the
cigarettes made, and which also receives the metallic cone thrown off the tube.
The invention is illustrated by the annexed drawing, in which
Fig. 1 is a front elevation of the apparatus shown open. Fig. 2 plan view of
the same.

page_text: The operation takes place by means of two principal movements. The tobacco
having been brought into the necessary place, the compressing and decompressing
lever for the tobacco is pressed down (first movement, as in Fig. 3). The tube of
paper being arranged around the exit-orifice for the tobacco roll or plug, the lever
actuating the ramming piston is then moved from the right toward the left (second
movement as in Fig. 2).
As will appear from the annexed drawing, this machine is composed of a frame A
forming a slide in conjunction with two plates A'. In this slide is guided the
compressing plate B combined with the abutting plate B'. These two pieces B, B',,
when approached towards each other leave a free space between them of a truncated
conical form. The plate B is connected to the lever C by the aid of two parallel.
rods C. This lever is pivoted in the frame by a pivot D; at its base it carries
two stops, one a for controlling the upper position, and the other 6 the lowered
position, (Fig. 3). The stop a rests against a portion of the frame and the stop b
against set screw b¹.
As can be seen from Fig. 3, as long as the point e has not passed the horizontal
line, running through D, the compression of the tobacco between the plates B, B',
takes place, and as soon as this point e has passed the horizontal line, the decom-
pression takes place and will impart to the roll or plug of tobacco a convenient
shape for leaving the machine and for taking its way into the tube of paper.
The transporting of the roll of tobacco is effected as mentioned hereinbefore by
a movement from the right towards the left of the lever E, pivoted at E¹ upon a
flat surface formed by the frame and carrying toward its middle a slide F in which
a tenon firmly fixed to the piston H is operated and which piston at this point is
made so as to slide under smoothly in the tube I fixed on the frame. The piston
and its curved blade, serve as a transporter and is the most important part of the
invention. They consist as already mentioned above of a portion prolonged by a
rod of smaller diameter H¹ carrying at its extremity a concave blade J, which I
call the impeller or transporter. Against this blade J the compression of the
tobacco takes place when the lever C is lowered and said blade penetrates, together
with the roll or plug of tobacco, the tube of paper.
As seen from the drawing the exit of the roll of tobacco takes place through
the tube K of conical form, on the projecting part of which rests, under slight
pressure, a suitably bent spring L. In order to facilitate the placing of the paper
tube around the tube K a conical accessory piece M is used (Fig. 1) adapted to
the purpose in view; this operation is effected by disengaging the tube K from the
spring which is lifted by bearing slightly on the bottom n of a lever N pivoted
at o. After the paper has been arranged, the lever N is released, which releases
the spring L. At the end of the course of the lever E (position shown in Fig. 2)
that is to say when the tobacco roll has almost entirely left the tube K, the lever E
puts pressure upon the lever N which automatically lifts the spring L allowing the
finished cigarette to escape.
The course of the lever N is controlled in upward and downward direction by
means of two studs i.
In prolongation of the piston and of the tube K a receptacle O is arranged
which can be regulated at any desired distance on a fixed rod P. by means of a set
screw Q.
In operating the apparatus constructed as shown in the annexed drawing it is.
sufficient to fill the chamber R with tobacco without fear of putting in too much,
then press down the lever C which by the plate or blade B will, between it and
the blade J, form the tobacco rolls and which will cut off and throw out the
surplus. The conical piece M is then forced into a tube K, a paper tube put on up
to underneath the support L which latter is lifted by means of the lever N which
is then immediately abandoned. These manipulations having been completed, the
lever E is forced sideways from the right towards the left and the cigarette falls
into the receptacle. The lever E is then brought back to the right, the lever C
lifted, and the apparatus is ready for a new operation.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In cigarette making machines :-
1. A lever combined with a compressing and decompressing plate or blade for
compressing and decompressing the tobacco, the said plate or blade also arranged
to regulate the quantity of tobacco to be introduced into the paper tube.
2. A lever combined with a ramming piston having horizontal and also displace-
ment movements.
3. The combination of a concave transport blade with the above mentioned
rammer or ramming piston.
4. The arrangement for drawing the tobacco by means of the said concave blade
acting as a transporter and being arranged in prolongation of the aforesaid piston,
all substantially as illustrated and described and for the purposes set forth.
