Improvements in Cigar Rolling Machines.
I, CLARENCE BENJAMIN SCHULTZ, of 64, Wilmersdorferstrasse, Charlottenburg,
Berlin, German Empire, Mechanical 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 :-
In some cases
My invention has for its object a better and more reliable method of rolling cigar
bunches into their wrappers and particularly of revolving the bunches around their
axis. For this purpose quite a number of devices have been in use.
the bunch has been stuck upon a revolving pin, in others it is being revolved by an
endless up and down band, in another instance again the revolving action is being
brought about by fingered claws.
But all these inethods have shown more or less defects, amongst others the following,
to wit:
The wrappers, the most valuable part of the cigar, have been torn during the
rolling process to such an extent, that the financial success of machine work is
seriously affected by it.
The drawing of machine made cigars was far from being satisfactory.
Besides, machine made cigars, as heretofore made, could be easily distinguished
from hand made cigars, and most smokers are prejudiced against the former.
While the
All these defects and failings my new device has thoroughly overcome.
bunch is being revolved by and between my longitudinal shapers, it is constantly
changing its form from circular to oval and vice versa, so that the motion of the
human hand is naturally imitated, less than one half of the circumference of the
bunch being held by one of the shaper pairs at the time. The filler of the bunch
is subjected to a loosening process, which opens air channels in the longitudinal
direction and thus insures perfect free drawing.
The wrapper as it is fed, is taken hold of by the shapers in its entire width, thus
avoiding the tearing of the wrapper, at the same time holding it more taut, which
gives to the finished cigar that smooth and soft appearance, which are the distinctive
features of the best hand made cigars.
In the accompanying drawing Fig. 1 represents a side view, Fig. 2 an upper view
and Figs. 3 and 4 show the range of the machine.
a, b, c, d, in Figs. 1, 2, 3, and 4 show two pair of wrapping shapers, the upper part
of which contains the hollow space, corresponding with the shape of the cigar to be
wrapped. Each pair is hinged upon a bushing (el and f¹) and swings upon rods e
and f. Below their fulcrum, e and f, these shapers are provided with guiding curves
a b c and d¹, which are shaped in such a manner that the rods g and h, sliding
up and down in the same, open and close the shapers, also holding them closed for a
certain time.
Rods e and fare connected to levers p and pl respectively q and q¹ and swing
around the axis of the cigar bunch and parallel with the same upon bolts s and s¹,
fastened to frame r and r of the machine. Besides, levers p, q, p¹, q¹ are
linked to eccentric rods i, k, i¹, k¹, to which latter rods g and h are fastened.
The eccentric rods i, k, i, k¹, are actuated by eccentric sheaves m, n, m¹, n¹,

page_text: which are revolved by shaft o. Shaft o has its bearings in frame r and r¹ of the
machine.
When shaft o is turned in the direction of the arrow, levers P and 2, Figs. 3 and 4,
swing around their fulcrum, bolt 8, and with them the two pair of shapers a, b,
and c, d, reciprocatingly. Levers p¹, q¹, swing in the same manner. At the same
time rods g, and h, fastened to eccentric rods i and k, slide up and down in the
guiding curves a¹, b, c¹, and d¹. Fig. 3 shows the mechanism at the moment,
when the shapers c and d take hold of bunch z, and shaper pair a-b let it go,
rods and h occupying the corners of the curves. In Fig. 4 shaft o with the
eccentric sheaves is turned about 90 degrees. Shaper pair c-d has hold of the
bunch and has turned it already a little piece. Rod h has approached the point
of suspension f, without however changing the relative position of c to d, a
consequence of the shape of the guiding curves.
Shaper pair a-b is moved by lever p towards the left, reaching out for a new
stroke, rody has passed downward by the angle in the guiding curve, opening the
shapers tongue-like. If shaft o is turned another 90 degrees shaper pair a-b will
take hold of the bunch and turn it in the same sense as c-d, while shaping pair c-d
has let go, reaching out for another stroke. Consequently the cigar bunch is being
revolved by the shapers in the direction of the arrow, at the same time receiving the
proper form.
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 :-
1. In a cigar rolling machine two pair of longitudinal wrapping shapers,
swinging parallel, taking hold alternately of the bunch and turning it at the
same time a little piece, also giving the cigar the proper form, substantially as
described.
2. In a cigar rolling machine with two pair of wrapping shaper,
taking hold of, turning a little and shaping at the same time th
device consisting of a driving shaft bearing eccentric sheaves, lev
the axis of a cigar, rods attached to the levers supporting the sh
to the eccentric rods and guiding curves, substantially as describe
