COMPLETE SPECIFICATION.
Improvements in Cigarette Making Machines.
I, MORITZ STERN Junior of 34, Kronprinzenstrasse, Frankfurt a/ M, in the Empire
of Germany, 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 certain improvements in cigarette making machines
whereby the cigarettes and also the plates for apportioning the tobacco necessary to
make one cigarette, are periodically operated by means of a crank in such a manner
that a cigarette can be made in the shortest possible time, and in which a double cam
disc is arranged on the crank axle for operating a lever adapted to hold the cigarettes
firmly whilst they are being filled.
In the accompanying drawing which illustrates a cigarette machine embodying this
invention:-
Figure 1 is a view in plan.
Figure 2 is a view in side elevation.
Figure 3 is a view in cross section, and
Figure 4 is a view showing diagrammatically a portion of this machine on a larger
scale.
Throughout the views similar parts are marked with like letters of reference.
In a casing a which is suitably made of cast iron, there is fixed on a shaft ba
drum c provided with a groove c¹. A crank d is keyed on this shaft b. This crank
has mounted on it at e a bar f which is pivotted at the point g with a rod / that is
capable of moving longitudinally. This rod is mounted preferably by means of the
eyes i and k which can be fixed upon the arm that is cast on the casing a. The
grooved in the drum c serves to operate a stud m that is formed with a shoulder, in
such a manner that when the drum e makes a revolution, the slide n which is guided
in the guide way o, is caused to make a corresponding to and fro movement.
Upon the casing a there is fixed a bar g; this bar is formed on its inside with an
oval recess in the same manner as that formed in the bar n¹ which is connected to the
slide n. A short mouth-piece
ris mounted at one side of the casing. The lever t
pivotted at the point s takes under this mouth-piece r. The lever t is acted upon by
means of a double cam disc a mounted on the shaft b, in such a manner that the
levert holds the cigarette-tube whilst empty. The cigarette tube when filled, is
released by the lever and can then be removed. A small spring y has a constant
tendency to force the lever away from the mouth-piece.
When the slide n assumes the position shown in Figure 3, the tobacco, as in all
machines of this kind, can then be introduced into the aperture u. On further
rotation, the stud m forces the slide n inwardly, and the latter closes the opening
gradually. During this rotation of the crank the bar facts to push the rod h at the
proper time in the direction of the arrow, and this rod / then passes into the interior
of u as soon as the slide n bas completely closed this opening. On then closing, the
tobacco in excess is pushed off, and the rod h is then caused by further rotation of
the crank to compress the tobacco to some extent and to draw the same through the
mouth-piece into the cigarette tube of paper which is mounted upon the mouth-
piece.
1.1 time ~ nota to

page_text: slightly lift the levert which then releases the paper tube as soon as the rod ŉ has
moved into its end position.
In consequence of the peculiar form of the groove in the drum e, the slide is
quickly opened and closed, this happening always when the crank has moved into
its proper position. By this means cigarettes can be made in the shortest possible
time.
Cigarettes thus made have the advantage over cigarettes made upon machines
heretofore used, that the tobacco in the same is filled quite uniformly and not too
tightly, and that cigarettes can be made of oval form upon this machine.
It will be understood that the shape of the cigarettes is not limited to this last
mentioned shape. By providing wedge shaped recesses in the bars n and q',
cigarettes could be made just as easily of round form in cross section, in which case
however, it is obvious that the short mouth-piece r upon which the paper tube is
mounted, would also be of a complete round form in cross section.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
(1) The improvements in cigarette making machines, substantially as herein before
described and illustrated by the accompanying drawing.
(2) A cigarette machine in which a drum such as c having a curved groove such
as c actuates a slide such as n through a stud such as m and in which a plunger such
as his moved periodically backwards and forwards through the medium of a bar
such as connected with the operating crank d, as and for the purpose set forth.
(3) In the machine specified in the preceding claim, the arrangement of a double
cam disc a on the drum shaft b for operating a lever t which partly holds the
: cigarette tube on the mount-piece r, as set forth.
