Improvements in Cigar Wrapping Machines.
I, JOHN BUNN, of Binghamton, in the County of Broome and State of New
York, United States of America, Machinist, 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 has particular reference to that part of cigar-making machines
for applying the wrappers to the bunches, and has for its object; first, to provide
the header of the wrapper stretcher table with means for giving it a universal
adjustment and thereby adapting it to fit cigars of a variety of forms: second, to
provide a wrapper stretcher roller, which, as the wrapper is being applied to the
cigar, will be adjusted to the shape of the cigar at all points automatically; third,
to increase the field of adjustment of the paste tube, and to provide one which will
form a part of the cavity for the end of the cigar when soft, instead of hard bunches
are being rolled; fourth, so to improve the construction of the means for cutting
a nick in the end of the wrapper as that the latter will more perfectly fit soft
bunches than heretofore and these objects are accomplished by the construction
of my invention hereinafter described and more particularly pointed out in the
claims.
Referring to the drawing:
Fig. 1 is a plan view of the part of the machine to which my invention relates,
showing in full lines the position of the swinging table and wrapper stretcher
roller at the beginning of the operation of wrapping the bunch, and in dotted
lines the position of said parts at the end of said operation, and also showing in
dotted lines, the parts concealed by the edge of the swinging table.
Fig. 2 is an inverted plan view of the wrapper stretcher table and parts carried
thereby.
Fig. 3 is a transverse section, on the line a-x of Fig. 1, showing more
particularly the construction of the wrapper-nicking devices.
Fig. 4 is a view, partly in section, showing the means for adjusting the wrapper
table vertically and also for permitting it to be turned.
Fig. 5 is a detail end view looking towards the recess for the reception of the
end of the cigar, and
Fig. 6 is a detail view showing the plate 26.
The same reference numerals indicate corresponding parts in each figure of the
drawing.
1 designates the wrapper stretcher table, the header end of which is formed
vith an elongated slot 2 and provided on its under side with a plate 3, having a
lepending sleeve 4 which is received within an opening 5 formed in the upper
nd of the standard 6 which forms one end of the main frame of the machine.
An adjusting screw 7 extends through said slot 2 and sleeve 4 and has a threaded
ngagement with the latter and bears against the lower wall of said opening 5.
horizontal screw 8 extends into the standard 6 and engages the sleeve 4 which
olds the table above in any desired adjusted position. The plate 3 is formed
ID 077

page_text: with an elongated slot 9, extending in a direction similar to that of slot 2, through
which projects a screw bolt 10 having a nut 11, the two opposite sides of the nut
engaging the walls of a groove 12 formed in the underside of said plate, whereby
it is kept from turning. It will be seen that after the screw 8 is loosened, the
table may be adjusted up or down by turning the screw 7 or swung in or out upon
said screw as a pivot, and also that it may be adjusted laterally on said plate, by
hand or by tapping it with a suitable implement, when the screw bolt 10 is
loosened.
13 designates the roller of the wrapper stretcher. This roller is tapered and one
of its ends is journaled in a flange projecting from the contiguous end of a bar
or plate 14, while its other end is received within a recess formed in a flange 15
projecting from said plate. This plate 14 is pivoted near its most remote end from
the header end of the stretcher table as shown at 14" and its other end is formed
with an opening 15" into which a stop pin 16 projects from said table. In opera-
tion said plate is caused automatically to turn upon its pivot 14 as the wrapper
is being applied to the cigar, and thereby adjusts said roller to the shape of the
cigar at all points down to its smallest end and keeps the roller at right angles
with the wrapper being wound specially upon the bunch. The automatically.
swinging table 17 usually employed in these machines, is used to swing the
plate 14 inwardly. The inner edge of the swinging table 17 engages the flanges
at the ends of said plate, as shown in Fig. 1 and a flat bent spring 18, secured at
one end to the table 1 and having its other end engaged with a pin 19 depending
from the pivoted end of said plate 14, operates the press the free end of said plate
toward said swinging table and automatically to return it to its original position
when the latter has been swung back after the bunch has been wrapped.
The header end of the wrapper stretcher table 1 is formed with a recess 20 of a
shape similar to that of one half the smaller end of a cigar, and is provided with
a laterally extending hollow bearing 21 through which projects loosely a sliding
bolt 22 which is provided with a spring 23 that operates to press said bolt out-
ward. The inner end of this bolt is preferably provided with a plate 24 which is
subjected to the pressure of a coil spring 41 seated on said table 1 and bearing
against the end of said plate and to it is attached, by a spring hinge 25, the upper
end of a plate 26, having an opening 27 forming the outlet for the paste. This
plate 26 is of a curved shape to adapt it to form with the recess 20, the conical
cavity for shaping the smaller end of the cigar, and it will be seen that by reason
of the provision of the spring pressed bolt and spring hinge it will be yieldingly
held toward the wall of said cavity and tightly against the side of the end of the
cigar or bunch and making the cavity adjustable to the size of the bunch desired.
This is especially desirable in the rolling of soft bunches. Extending from the
plate 26 is a tube 27" to which the rubber tube commonly used for conveying the
paste from the paste receptacle is attached and said paste flows to the plate 26
through said tube 27 and issues to the head of the bunch through the opening 27
in the plate.
The header end of the wrapper stretcher table is further provided with a longitu-
dinally movable bolt 28 normally held upward by a spring 29. This bolt extends
through the table and its lower end is provided with a laterally projecting pin 30,
which extends into slots 31 and 32 formed in the ends 33 and 34 of cutting
blades 36 and 37. These blades are approximately | shaped and are arranged
one upon the other in the relative positions shown best in Fig. 3, so that the slots
therein will diverge when the blades are in their normal positions. They are
pivoted at their bends upon the pin 35 which is secured to the rear part of the
table 1. Obviously pressure applied by the thumb of the operator to the upper
end of said bolt 28 depresses the same and causes said pin 30 to traverse said
slots 31 and 32, thereby turning the cutting ends 36 and 37 of the blades toward
each other, and forming a sheer cut or nick near the end of the wrapper as it
approaches on the roller 13. This is done just as the operation of winding the
wrapper on to the bunch is about completed, as it is found in winding soft bunches,

page_text: the wrapper nicked before it is put on the table does not usually fit as there is
always more or less stretching of the wrapper in winding.
The spring 29 operates automatically to return the sliding bolt and cutters to
their original positions when pressure on the said bolt is removed. In order to
guide said bolt in its movements, its lower end is formed with a longitudinal
groove 38 which receives the end of the guide pin 39 and in order to limit the
extent of movement of the blades in opening, a stop pin 40 is arranged to engage
the lower end 33 of the blade 36 when the blades have opened the required dis-
tance. From the above it will be seen that I have provided a cigar wrapping
mechanism having very important advantages and while I prefer the detail con-
struction of the parts, such construction to be best adapted to accomplish the
several ends in view, yet I do not wish to be understood as limiting myself thereto,
as many of the details may be changed without departing from the spirit of my
invention.
