An Improved Cigar Bunching Machine.
I, ALFRED HEYMANN of Düsseldorf in the German Empire, Merchant, do hereby
declare the nature of this invention to be as follows :-
This invention relates to a machine for bunching together the filling tobacco and
outer diagonally placed wrapper tobacco leaf into the form of cigars.
In the accompanying drawing Fig. 1 is a side view of the said machine; Fig. 2 a
vertical longitudinal section thereof through line A B of Fig. 4; Fig. 3 a vertical
cross section through line C D of Fig. 1; Fig. 4 a top view, Fig. 5 a vertical cross
section through line E F of Figs. 1 and 2.
It is composed mainly of a frame A having two side parts connected together at top
by a curved rolling table A¹ to the front part of which a reciprocating bunching or
rolling apron is fixed by one of its ends. The rolling table A¹ is formed at the back
with a deep curved recess C to allow of the bunching apron being entered therein and
formed into a suitable fold or bend for the reception of the tobacco it is desired to
bunch into the form of a cigar. A horizontal shaft D on which the reciprocating
driving pulley E is fixed is mounted crosswise in the frame, each of its extremities
outside the frame carrying a lever F. These two lovers extend upwards from the
horizontal shaft D and at top carry a roller G crosswise over the curved rolling table.
The levers F and roller G are balanced by a counterweight G¹ carried on the
horizontal shaft D between the sides A of the frame. A second roller H mounted in
bearings at and in the back part of the sides of the framo A has fixed to it the other
end of the bunching or rolling apron. On one extremity of this roller outside the
frame is fixed a disc provided with a number of holes arranged in a circle by which
the roller is adjusted and fixed by a pin being passed through one of them into a hole
or recess in the side frame. A handle at the opposite end of the roller or on its
spindle serves for turning this roller in either direction, for the purpose of adjusting
the bunching apron to the desired length which varies with the diameter of the
cigars to be made.
In operating the machine the bunching or rolling apron is passed down into the
deep curved recess in the rolling table so as to form a fold or bend into which is
introduced the tobacco to be bunched into a cigar, the outer covering or encircling
leaf being first laid diagonally on the said apron. The driving pulley is then operated
by treadle so as to turn through about one fourth of a revolution, and with it also the
two side levers and roller mounted on their upper ends. The roller in passing through
the said distance of about one fourth of a revolution carries along with it the bunching
or rolling apron so as to bring the fold containing the tobacco over the rolling table
rolling it into the desired form of cigar, which by the time the side lever movement
has come to an end is discharged from the apron into the hand of the operative or into
a receptacle placed or fixed for the purpose. The operative then releases the treadle
to bring by the action of the counterweight the side levers and roller back again into
the commencing position.
As one end of the bunching or rolling apron is fixed to the front of the machine
and the other end to the adjustable roller at the back of the machine the fold of the
apron owing to the form of the rolling table tends to become narrower and longer,
bunching the tobacco in a manner equal to best hand work.
The machine may be worked by hand instead of by treadle by fixing handles to the
side levers.

An Improved Cigar Bunching Machine.
I, ALFRED HEYMANN of Düsseldorf in the German Empire Merchant 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 a machine for bunching cigars or forming the interior or
filler of the cigar and lapping the binder or outer wrapper leaf around the same.
The improvements refer mainly to the form or construction of the working table,
to the form or construction of the levers or oscillating frame which carries the
bunching roller, to the means for fixing and for adjusting the length of the bunching
or rolling apron, and to the means for imparting motion to the oscillating frame.
In the accompanying drawing Figure 1 is a vertical longitudinal section Figure 2 a
side elevation showing various positions of the oscillating levers or frame. Figure 3
a vertical cross section on line CD Figure 2, Figure 4 a vertical cross section on
line EF Figure 2 and Figure 5 u plan partly in section.
The frame A of the machine has two side parts connected together at the upper
part by a working table A' of a peculiar curved form presently to be described. To
the front part of this table is fixed one end of the bunching or rolling apron F, the
other end of which is fixed by screws in the manner shewn to a roller E situated at
the back of the machine and some distance above the table A'. This roller E is
mounted in bearings in side standards of the frame A and carries at one end a worm-
wheel D into which gears the worm D. By turning the latter the apron F can be
more or less coiled round the roller E and the required slack given to the apron
accurately and conveniently according to the thickness of cigar that is to be made by
the machine.
In the frame A works the oscillating frame UGH by preference made in one
casting. It, consists of two levers with counterweights G mounted on the
fulcrum pin with end bushes as shewn. The upper end of the levers (carry between
them the bunching roller B in the well known manner. In Figuro 2 the oscillating
frame is shewn in six different positions which are marked accordingly.
The table A is curved concentrically with the oscillating frame from about the
position to the position IV, but declines towards each ond that is to say slanting
down to the deep wide half round recess T at the back, and slanting down or
terminating in an ellipse at the front. The recess T gives the apron F in the
position of rest sufficient room for forming a bight for placing the required filling
material therein. The elliptic form of the front of the table from position IV to
position VI has specially for object to ease the forwed bunch and prevent it from
becoming too tight or choky.
I stated that the roller E should be some distance above the table A', and it
should be so high up that as shewn in figure 2 in the various positions of the
apron the upper end of same is quito free and cannot even in the extreme
positions FV and VI touch the loop. 1 thereby prevent the bunch from merely
sliding, and not rolling on the table A¹ during the operation.
The driving pulley H is by preference eccentric as shown for the purpose of
increasing the leverage at that stage (in position IV) where the friction and pressure
of the bunch are at the highest. The machine thus obtains a perceptibly easier and
evener working which has a beneficial influence on the bunching operation. Further
in order to make the machine as noiseless as possible a buffer P is provided at each
side for the levers C to abut against in the back stroke for commencing a fresh
operation. The levers C are also shielded by the guards S fixed on the framing,
for the purpose of making it impossible for the operator to take hold of them with
the lands in order to ovecome extra or undue friction. Such friction would only
occur if the workman were to put too much filling material into the loop of the
apron which would produce a cigar rolled too tightly and without proper draught
through.

page_text: In operating the machine the levers C are put into position I, to which the
counterweights G always return them when the treadle after each operation is let
go and the apron is pressed into the fold or bend z in the recess T, and tobacco to
be bunched into a cigar put in, the outer covering or binder having been first laid
diagonally on the apron. The driving pulley H is then operated by the treadle and
strap j so as to turn through about one fourth of a revolution or say 100 or 110°
and with it also the two side levers C and roller B mounted on their upper ends.
The roller carries along with it the loose roll or bunch of tobacco to the position II
While carried on to the
figure 2 where the binder has already been caught.
position V the binder has been lapped round the bunch in the required manner
whereupon until the position VI the loop is being shortened and widened, and the
finished bunch is discharged from the apron into the hand of the operative or into a
receptacle placed or fixed for the purpose.
By the worm wheel D the apron can be adjusted for a cigar thickness of from
3 to 20 m.m. or say to of an inch.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is:-
First. In cigar bunching machines the form or construction of working table or
surface substantially as and for the purposes set forth.
Second. In cigar bunching machines the means for adjusting the length of the
rolling apron substantially as set forth.
Third. In cigar bunching machines the eccentric driving pulley H substantially as
and for the purpose set forth.
Fourth. In cigur bunching machines the placing of the point of attachment E for
the one end of the apron so high above the table as to prevent the loop of the apron
from touching the upper end of same in any position substantially as and for the
purpose set forth.
Fifth. In cigar bunching machines constructing the levers C with pulley and
counterweights substantially as set forth.
Sixth. The construction of cigar bunching machine shown on the drawings.
