Cigar Core wrapping Machine.
I, JOHANN RUDOLF SCHMITT, of 33, Frankfurterstrasse, Oberrad, Hessen-Nassau, in
the Empire of Germany, 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:-
The object of this invention is a cigar core wrapping machine which, as compared
with similar machines heretofore constructed, has the advantage of allowing the
mechanical enwrapping of cigar cores in various shapes or forms, this being effected
by the insertion of moulds of different forms according to the shape required for
the cigars. The tobacco feed is automatically regulated by the machine, so that the
operation may be constantly unform.
The machine is shown, by way of example only, in the accompanying drawings
wherein Fig. 1 is a side view of the machine. Figs. 2, 3 and 3 show the feed
mechapisin with its stopping device throughout the different positions of the part.
Fig. 4 shows the detail of an appliance which prevents the tobacco from separating
when being cut and Fig. is a side view of the same. Fig. 6 is a top view of the
driving mechanism mounted on the two main shafts. Figs. 7 and 8 show the driving
gear for the travelling band h. Figs. 9 and 10 show a rolling appliance for straight
and conical enwrappings respectively.
The tobacco is fed by the travelling band a, Fig. 1 and shot in suitable lengths
into the former or mould e which has a size and form corresponding to one of the
cigar shapes provided for, wherein the said tobacco is pressed by the ram g and
whence it is subsequently fed by the slide k connected to the lever ² out of the
mould e on to the band . To be able to feed on the tobacco in a compact form on
the band h, rails are provided above the said band h, and can be fitted accurately
against the mould e so as to hold the tobacco throughout the length of its travel
into a proper form. After the tobacco has been fed up to the knife by the band h,
the tobacco mass which has to be made into a cigar and enwrapped is detached and
driven by the ram rod v on to the enwrapping inechanism.
The whole machine consists accordingly of the following parts:
1. Feed mechanism with stopping device.
2. Continuous feed mechanism.
3. A pressing device when cutting off the tobacco.
4. Mechanism to facilitate the expulsion of the tobacco, after the cutting off
operation, out of the pressing applicance which held it tightly.
5. Enwrapping or coiling mechanism.
FEED MECHANISM WITH STOPPING DEVICE.
The tobacco is placed on the travelling band a (Figs. 1 and 2) which feeds the same
in separate predetermined quantities or bulk into the mould e. The said band a
runs over two rollers b. one of which is suspended to a set of levers 1 1,2 1,3 1,4

page_text: carries an eccentric 6 (Figs. 1, 2 and 6) which actuates the lever 65 and thus imparts
an intermittent motion to the travelling band a. The ratio of transmission from
c to c is 14, and hence the band a moves four times, while the band h moves
only once, in consequence whereof the tobacco is fed at intervals to the mould e
so that it can be better ramined into the mould e. After the tobacco has left the travel-
ling band a it arrives upon a guiding piece and is conveyed thence to the mould e by
a second travelling band a¹. The travelling band a¹ is set in motion by one of the
rollers b which likewise, by the aid of a connecting rod 67 and of a pawl and ratchet
gear, imparts motion to a third roller b above, so that the whole feed mechanism
is really driven by the lever 65 and the eccentric 6°. In case the tobacco should not
drop uniformly from the guiding piece d into the former or mould, this defect can
be readily remedied by the aid of the knife f (Fig. 1) which passes close against
the front side of this guiding piece or inclined plane d and pushes the tobacco on
the guide d into the mould e. The knife is fixed to a lever f¹ which is arranged
to turn on a pivot or fulcrum secured to the framework. The up and down motion
is caused by the shaft B with the aid of the crank f2 and the connecting rod f³.
The mass of tobacco in the mould or former is subjected to the action of a
ramrod g having a striking surface corresponding to one of the cigar shapes selected
and serving to properly arrange the tobacco in the said mould or former.
slide subsequently knocks the tobacco out of the mould on to the second travelling
band h. The ramrod g is secured to a bell crank lever g¹ fulcrumed to the frame-
work and actuated by means of the connecting rods g2 and g³ by the cam g
mounted on the shaft. B. This cam g has on a portion of its periphery a sharp
notch or recess as can be more clearly seen in Fig. 6 so that at each rotation of
the shaft B and hence of the cam mounted thereon in the direction indicated
by the arrow in the said figure, the ram rod or pestle is allowed a sharp drop into
the mould or former.
The
To prevent, during the feed of the tobacco, the travelling bands a, a¹, from delivering
too great a quantity of tobacco in the former or mould e and on to the travelling band
h, a device is provided for the purpose of stopping the feed mechanism in time.
This device is shown in Fig. 3ª in a released or inactive attitude, while Fig. 3 shows
the position of the same when the travelling band is at a standstill. As soon as the
space between the band h and the adjusting bar is overfilled, the lever k², which is
brought back into its normal position by a counterweight, being unable to accomplish
its fill motion or trajectory causes the lever 23, connected to the lever k² by the
connecting rod 2, to fall out of contact of the lever which becomes accordingly
free.
In consequence thereof the lever i is released at y and the tobacco cannot be
fed forward any longer, as the shaft bs is hemmed in by the lever 6°. This shaft b8
is, as shown, the driving shaft for the two travelling hands a and a¹ and is set in
motion by the lever and the eccentric. The lever 65 is brought back into its
original position by the counterweight. As soon as the tobacco which is on the
travelling band h is fed forward by the latter, the lever k² is allowed to finish its
course and the lever is enabled to come into close proximity to the lever (Fig. 3^)
thus releasing the lever i at the point y. In consequence thereof the lever 69 and
the shaft 68 are likewise released in order to be again actuated by the eccentric 6º.
The lever is held by the weight 610 in the position shown in Fig. 3 until it is raised
again by the lever 3 (Fig. 3A).
As soon as the tobacco has left the mould or former e it is fed on to the travelling
bandh which runs over two rollers h¹ and conveys the tobacco further on. Over the 5
band are arranged adjustable bars or ledges which can exactly fit the mould or
former e and keep the tobacco in its original form. The motion of the travelling
band his transmitted by the main shaft A with the aid of the connecting rods
h2, h3, h4, h³, and the crank he mounted on the said shaft A.

page_text: CUTTING OFF DEVICE WITH CLAMPING MECHANISM.
At the outlet end of the hollow space between the travelling band h and the bars
is situated the dividing knife m (Figs. 4 and 5) which cats off at a determined angle
the tobacco fed thereto by the travelling hand and so determines the length of the
cigar. It is moved up and down by the shaft A with the aid of the arm m³, the
lever m², the connecting rod m³, and the frame m (Fig. 4). To prevent the tobacco,
when about to be cut off, from losing its compressed form and becoming loose, the
mechanism shown at an enlarged scale in Fig. 4 and in side view in Fig. 5 next comes
into requisition. When the tobacco is fed by the travelling band h, on to the bar n,
the frame m (Figs. 4 and 5) with its knife stands at the highest possible position
allowed by the mechanism m³, m², m³. As the knife frame ascends, the pin o
(Fig. 4) bears against one arm of the lever p which extends across its way and causes
the same to turn on its fulcrum pl. The other arm of the same lever p is connected
with a pressing device in the following manner that is to say: Two levers 9 are
fulcrumed on q¹ upon the plate n and engage in the notches or recesses of the guiding
piece (Fig. 4). To the latter piece r is fixed the sheet or apron 8 which has a shape
corresponding to that according to which the cigar is to be enwrapped, and the
object now is to increase the opening formed between the guiding piece and the
sheet or apron 8 before the introduction of the tobacco and during such introduction,
and to decrease the size of this opening immediately before the cutting off. As the
lever P is turned on its fulcrum by the pin o, on the frame m ascending, the same
lever carries away with it one of the arms q connected with a slotted connecting rod
t and capable of turning freely on its fulcrum q', whereby the opening between the
plate or aprons and the plate n is increased for the introduction of tobacco. Owing
to the two arms or levers q being connected together by the links r the opening of
the mould between the apron 8 and the plate is always fully disclosed although the
lever p is arranged on one side of the machine only. The spring u, as the frame m
descends and the tobacco is cut off, effects the closing of the mould, the pin o releasing
the lever p before contact takes place between the knife and the tobacco, so that the
latter may be firmly gripped by the mould ere the knife comes into operation. After
the latter operation the plate n is turned on its horizontal axis (Fig. 5) and the whole
of the mechanism p, q, r, s, t, u, assumes such a position as to offer no obstacle to the
tobacco being expelled from above by the plate 4. The plate n with its accessorial
parts is swung round by the eccentric arm n² mounted on the main shaft A with the
aid of the connecting rods n³, n², n³.
EXPULSION OF THE TOBACCO.
The expulsion of the tobacco is effected by a bell crank lever g fulcrumed on the
framework and set in motion by the cam v³ mounted on the main shaft by the aid of
the levers v, 2. The lever vis provided in front with a plate 4 which can be
renewed or exchanged according to the different forms of enwrapping required. The
driving of the remaining parts of the mechanisin the motion of which is subsidiary to
that of the lever v fulcrumed on v³ will be described further on in connection with
other devices or appliances. To guide the plate within the mould formed between
the apron s and the plate n in order to knock off the tobacco, there is fulcrumed
at won the framework a lever w which by means of the roller of the lever v causes
the mould to be opened. Before the plate v comes into contact with the tobacco, the
roller has pushed the lever w to one side and the lever x (Fig. 4) which is
connected to the lever w is carried away therewith. In the path of the lever x (Fig. 4)
projects the lever q, as soon as the plate n with its accessorial parts has been turned
around its horizontal axis. This lever q is accordingly drawn and operates the opening

page_text: plate 4, it arrives on the curved track G¹ (Fig. 1) upon which is placed the tobacco
leaf destined to be coiled or wrapped around the cigar core, by means of rolling
mechanism. For this purpose, a rolling hand or strip is provided and fixed as clearly
shown in Fig. I upon the rolling track G¹ and has such a length as to be able to fully
enclose the cigar core as soon as the rolling appliance has passed over it without
interfering with such rolling operation. The rolling appliance varies in shape
according as a cylindrical or conical cigar is required and is actuated to and fro by the
cam H mounted on the main shaft A by means of the connecting rods and
levers H1, H2, H³, H* (Figs. 1, 9 and 10). This appliance consists, for cylindrical
enwrappings, of a fork J carrying a roller J³ and mounted upon a lever J2 fulcrumed
on J. J2 is supported by points and is set in motion by the bell crank lever H³
fulcrumed on H in such a manner that as soon as H³ moves forward J2 is carried
away therewith. The counterweight K (Fig. 1) pulls the lever J2, as soon as the
lever H3 moves backward, likewise to the rear. To wrap up conical cigar cores, the
rolling appliance which is to be used as a substitute for the above is constructed in
the following manner (see Fig. 10). The lever J2 is held by the pointed screws L¹
in the bracket L so as to be free to turn in a vertical direction under the action of the
connecting rod H. The latter is connected to the lever H3 and causes it to turn upon
its fulcrum on H³. To be able to turn the bell crank lever J2 on the screw points L'
at the same time, the latter is connected to H2 by the connecting rods or links Hand
H7, so that when the lever H³ oscillates, the lever H2 assumes a circular motion. In
consequence of this motion the distance on one side of the rolling appliance is greater
than on the other side and as a conical roller instead of a cylindrical roller is placed
in the fork J, a conical coiling or enwrapping is produced. When the rolling down
of the cigar core over the curved or rolling track G is ended, the same falls
subsequently in the gutter or groove G2 provided at the end thereof and is withdrawn
by hand in order to receive its final covering or leaf further along.
As, in consequence of the driving gear shown fully in Fig. 1, the mechanism
h2, h3, h, h³ and h and the rollers over which the travelling band he runs are moved
sometimes forwards and sometimes hackwards, there must be another device added
for the purpose of ensuring that the travelling band will constantly move in the
same direction. For this purpose, the rollers over which this band h travels are
constructed in the manner shown in Figs. 7 and 8. They consist of an inner part 1
and an outer part 2, the inner surface of the latter part being provided with suitable
cavities or recesses wherein are placed balls of suitable diameter. As the inner
part 1 turns in the direction indicated by the arrow shown in Fig. 7, the rollers enter
the deepest parts of these cavities or recesses formed in the outer part without
carrying the latter part away with them. When on the contrary the inner part 1
turns in the direction indicated by the arrow in Fig. 8, the balls 3 are locked in the
cavities or recesses of the outer part 2 so that the latter must follow the motion of
the inner part 1 of the said rollers. There remains now to indicate in detail the
position of the various driving parts on the two shafts A and B as well as their mode
of operation, which will form the subject matter of the following paragraph, reference
being more particularly made to Fig. 6 of the drawings.
66 is a cam for driving the travelling band a. f is a crank for moving the knife m.
g is a cam for moving the ram rod g. is an eccentric for moving the sliding bar k
