Improvements in the Construction of the Cutting Device in Cigar
Making Machines.
I, CLARENCE BENJAMIN SCHULTZ, Mechanical Engineer, of 64 Wilmersdorfer-
strasse, Charlottenburg, Berlin, 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 :-
My invention relates to improvements in the construction of the cutting device
in cigar making machines.
It is very desirable that in cigar making machines the tuck is cut straight
across without breaking the wrapper. The contrivance hereinafter described is
intended to fill this want. Frame m, of the machine is provided at the proper
places with grooves or guides g, in which are sliding two parts a, and each of
which bears one of the concave blades a', and 6'. The finished cigar z, is placed
between the two sufficiently opened knives. Since the parts a, and b, for good
reasons must be fairly thick or heavy it becomes necessary in order to secure a
clean cut that one knife a¹, be brought close up to the cigar, while the other 6',
cuts square across. This done both knives withdraw in order to make room for a
new bunch to be rolled into its wrapper and cut as described.
With almost all cigar rolling machines the coupling and uncoupling of the
power and other functions, here not to be mentioned, are effected by a shaft
turned forward and backward by a handcrank or lever. Now since the machine
must be ready to receive a new bunch after the forward movement of the lever,
during which operation the first bunch is cut, it is desirable that the described
movements of the knives, namely the opening and closing, be effected by turning
the shaft in only one direction. For this purpose part a, is provided with an
extension a, Fig. 3, bearing on one side the double lever e, Figs. 1, and 2,
swinging on screw f, and on the other side the pin k. Above this extension a
slot a', is cut, through which pin 1, fastened to part b, reaches into the sphere of
action of double lever e, Figs. 1, and 2, of which the latter is a cut of the former on
line -y. Spring v, keeps the double lever e, against stud 1, as long as the
entire cutting contrivance is not set at rest by the pressing down of part c, which
operates upon stud t, of double lever e. Lever h, which swings on screw u, of
part b, is forked at its lower end and enters groove r, Fig. 2, of part q. Besides
this lever link i, swings on the same screw u, and slides with a slot on stud k, of
part a.
When part b, is moved in its guides to the right, Fig. 1, the link i, strikes
noses, fastened to the frame of the machine, and thus pushes part a, acting upon
stud k, to the left. This opens the knives. The cutting device is put into
operation by turning shaft o, and with it part q. Part q, bears two studs n, and p
which are thus arranged that n, when part q, is turned, pushes double lever e, ahead
and by it part a, a short distance to the right, until the shoulders a', Figs. 1,
and 3, reach the guide g, and part b, to the left. Thus knife a¹, is moved up to
the cigar z, and knife 61, passes straight across and cuts the tuck.
Now when continuing the motion of shaft o, stud p, touches the forked lever h
and draws part b, by screw u, again to the right, until the shoulders 6, Fig. 4,
strike the guide g. Part a, is being pushed simultaneously, as already described,

page_text: by means of the link i, towards the left, the knives are open again, the finished
cigar is removed and a new bunch may be put into the machine.
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 cigar making machines a cutting device consisting of two parts each
carrying a knife substantially as and for the purposes herein set forth.
2. In such a device a lever h, and a double lever e, for opening and closing the
knives by turning the actuating shaft o, in only one direction, substantially as and
for the purpose herein set forth.
Dated this 30th day of November 1896.
