Improvements in or relating to Apparatus for Making and Inserting
Cigarette Mouthpieces.
A communication from CARL RICHARD MARTIN, Machine Manufacturer, of Leis-
nigerstrasse 4, Dresden, Pieschen, Germany.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
-
The present invention relates to the production of cigarette mouthpieces and
their insertion into the corresponding cigarette tubes or shells, and is intended to
solve the difficulty of producing these mouthpieces from one endless paper band.
Apart from the fact that the ready rolled mouthpiece is severed from the band
while the next one is cut with an oblique end, the task requires an essentially
different treatment of the paper when being rolled to form the mouthpiece, as
compared with the method of producing cigarette mouthpieces, in which a series of
pieces of paper to be rolled into mouthpieces are introduced ready cut and sepa-
rately. It will therefore be seen that essential differences arise between the pre-
sent invention and that described in Patent No. 88113 of the German Empire.
Whereas in the latter apparatus the point of the paper strip is held loosely by
friction in the slit of the roller spindle and is loosely rolled in the large shell 5
according to the present invention while the strip still forming part of the supply
band is firmly taken hold of by a rolling-up device, acting like curling tongs and
olled, the inertia of the supply roll of paper aided or regulated by a brake device
assisting in causing the paper to be rolled up firmly.
By this means not only is it made possible to employ a continuous supply band
of paper but the natural stiffness of the paper is thereby broken or reduced
although not to such an extent as to deprive it of all elasticity, it being still
able to unroll to a slight extent; when left free inside the cigarette shell, though
not so decidedly as is the case with mouthpieces produced in the manner described
in said patent. Such decided unrolling within the shell has the effect of press-
ing the windings close to the shell, leaving a comparatively large central space
occupied only by the small S-shaped end of the paper, which will imperfectly
retain short or small tobacco within the cigarette; whereas the elasticity of the
spiral formed according to this invention is sufficiently reduced to cause the spiral
to loosely but effectively fill the end of the tube or shell which it is destined to
occupy.
The firm rolling-up of the paper is moreover increased by the arrangement of a
presser acting radially on the rolling-up device, and the paper spiral forming
upon it.
The additional advantage arising from the avoidance of the difficulty of having
to feed, regularly and singly thin sheets of paper from the supply stacks, needs
no further comment.
It is only necessary to mention as an example the automatic post or business-

page_text: card machines, which all suffer from the drawback referred to, which has not been
remedied in spite of repeated efforts; and compared with post or business cards,
the handling of these thin papers is very much more difficult.
In the accompanying drawings,
Fig. 1 is an elevation of the apparatus partly in longitudinal section on the
line II of Fig. 2 the paper feeding and cutting devices opposite the rolling-up
device being however omitted.
Fig. 2 is a plan view showing also the feeding and cutting devices.
Fig. is a vertical section through the feeding, cutting and rolling up devices
on the line 111-III Fig. 2.
Fig. 4 is a transverse section on the line IV-IV Fig. 1.
Figs. 5, 6, 7, 8, 9, 10, 11, 12, and 13 being details views hereinafter referred to.
The paper band p, (Fig. 3), the breadth of which is equal to the length of the
mouthpieces to be formed passes from a bobbin or holder over the feeding device a,
guide plate under the knives c and d and enters with its point (see Fig. 6)
between the open jaws of the rolling-up device e which is at that time in the
position shown in Fig. 1.
The rolling-up tongs are fixed with their shank in a tube 1 which is revoluble
in the bearings but cannot be longitudinally displaced said tube being rotated
by means of wheel gearing (Figs. 1 and 13) as long as the semi-circular or seg-
mental toothed wheel 2 fixed on and driven by the shaft is in gear with its
corresponding wheel. When the tube is at rest the jaws of the rolling up tongs
are open, the jaw 5 pivotted at 4 (Figs. and 5) being pressed down by a spring.
As soon as the pointed edge of the paper comes into position between the jaws of
the rolling up tongs the cam dise 6 by means of the lever 7 and ball joint con-
nection 8 presses forward the plunger shaft 9 which is revoluble with the hollow
spindle 1 and thereby moves forward the thin rod 10 and its end ring 11 in doing
which the lever 7 passes from position I into the position II (Fig. 1) In conse-
quence of this change of position the rang 11 is pushed over the shoulder 12 of
the jaw thereby closing the jaws over the paper strip and firmly holding it.
At the same time the rolling up tongs are set revolving thus winding round
them firmly and tightly a certain length of the paper strip a presser 13 (Figs. 7
and 8) actuated by a spring (Fig. 1) also contributing to cause the paper spiral
to be wound up tightly This part of the process being finished the break in the
series of teeth 14 (Fig. 13) allows the rolling up tongs to rest for a short time
During this time the already partly formed spiral is cut off from the paper band
the new end of which is cut off obliquely at the same time. The first operation
is effected by the knife d (Figs. 2, 3 & 11) cooperating with an under knife
(Fig 3) and the second by a knife & the edge of the plate 15 serving as the under
knife. The knife d is attached as a lever arm to a shaft 16 (Fig. 2 and 11) which
is intermittently operated by means of connecting rods and a cam disc as repre-
sented in Fig. 11. A plate 17 (Figs. 2 and 3) fixed to both the knives d and c
communicates the movement of the cutters to the cutter e which is pivotted upon
a fixed point 18 (Fig 10) a spring 19 attached to the cutter c acting to lift up
both the knives after each cut.
After the paper spiral has been cut off, it is given a few more turns by the
renewed engagement of the toothed gearing following the recos in the cog
wheel 2 (Fig. 13) in order to wind up the rest of the strip forming the mouth
piece. At this moment a bolt or pawl 20 (Figs. 2 and 13) falls into a recess in
disc 21 of the hollow spindle 1 owing to the raised edge or cam surface 22 on
the wheel 2 releasing a lover 22" operating the pawl. The rolling up device at
this portion of the pawl (Fig. 1) remains at rest until the new end of the paper
band is introduced.
During this period of rest the jaws are first cased to allow the mouth piece to
be pushed off into the cigarette shell. For this purpose the cam disc 6 moves
the lever into the position III (Fig. 1) which causes the ring 11 to be pushed
beyond the shoulder 12. The rolling up tongs are thereby eased or partly opened

page_text: the ring being somewhat wider than the closed tongs. The jaw 5 is eased a little
(Fig. 9). The presser 13 which otherwise would prevent the easing of the spital
being lifted by the edge, of the forwardly moving ing and kept in that posi-
tion until the mouth piece has been shifted from the rolling up tongs into the
cigarette shell or tube. Before the mouthpiece has completely entered the
cigarette shell it will have passed out of reach of the presser and may therefore
expand inside the shell so as to become securely held therein. The apparatus
represented in Figs 12 and 9 serving to hold the cigarette tubes or shells, filled
with tobacco up to the space reserved for the mouthpiece form no part of this
invention and therefore require no description any convenient form of holder being
applicable
The shell being now removed the lever returns to its initial position I; the
ring 11 passes back over the shoulder 12 and the jaws of the rolling up device are
agam open to receive the next strip of paper to be rolled up. The point of the
strip which after cutting off the mouthpiece, only reaches to the knite is made to
move a little forward to bring the point within reach of the jaws of the rolling
up tongs as seen in Fig. 6. This is done by the forked fever 23 and spur
wheel 23 (Fig. 12) acting on the carrier a to move the strip p forward to the
required extent During the forward movement of the carrier a the strip is held
fast on the little edge 24 by the clamp 25 actuated by a spring Fig. 3.
reaching the limit of the forward movement the clamp 25 is released by its pro-
Jection 26 striking against a fixed projection 27 to ensure it from being wedged
during the first movement. The carrier being drawn back after its forward
movement by the spring 28, the clamp will act as a brake when the end of the
paper band is being rolled up to form the niouthpiece.
On
The triangular piece of paper remaining after the mouthpiece is cut off is waste
paper
The above described apparatus may be used either independently by itself or
conjointly as part of a machine for producing cigarettes provided with mouthpiece.
