Improvements in Cigar Making Machines.
I, DUKE WILLIAM BULLARD, of No. 49, Queen Victoria Street, in the City
of London, Engineer, do hereby declare the nature of this invention to be as
follows:-
In my previous Specification No. 5455 of 1895 I have described a machine
for making cigars by rolling a bundle of tobacco and a leaf or leaves twined over
them in a cavity between a number of rollers all revolving in the same direction
the uppermost roller being mounted in a hinged frame forming a lid which is
opened to give access to the cavity for feeding the tobacco and removing the
finished cigar.
My present invention relates to improvements in a machine of this kind whereby
I render it more rapid and efficient in operation.
Each roller consists of three parts in length, a middle part which is cylindrical
and two end parts which are conical, and which have their axes inclined to the
axis of the middle part so that the end parts of all the rollers converge to form
the tapered ends of the cigar. One of my improvements relates to means of
coupling the end parts of the rollers to the middle parts. For this purpose I bore
into the end of each a longitudinal hole across which at a little distance from the
end I fix a cross pin. Into the two holes I insert a cylindrical piece of metal
which has a slot at each end, the one slot at right angles to the other. The two
pins being engaged in the two slots, the end part of the roller is caused to revolve
with the middle part. For cigars of certain shapes, each roller may be made
in a different number of parts clutched together in the manner described. For
driving the rollers I provide in each cylindrical part sunk teeth; I gear the
teeth of the two lower rollers to a toothed wheel and also to two lateral pinions
which gear with the teeth of two side rollers. The teeth of one of these gear
with a pinion which gears with the teeth of the top roller.
This roller is mounted in a frame which can turn as on a hinge, the axis of
which is the axis of the pinion last mentioned, so that this pinion, whether the
top roller is raised or lowered, always remains in gear with it and with the
adjacent side roller. Springs on the axis of the pinion urge the top roller to
lift when it is free, but it can be closed down by hand and held by a spring catch,
on releasing which it springs up exposing the cavity formed by the rollers.
Under the table immediately in front of one end of the machine I provide a
box containing paste or gum, this box having in it a piston which can be advanced
by a hand screw or otherwise so as to force some of the paste or gum up through
a slot. As the covering tobacco leaf is turned in between the rollers, its end
part in passing over the slot receives a coating of paste or gum which causes it
to adhere to the body of the cigar when it is twined on it. In order to prevent
the end of the covering leaf as it enters the cavity between the rollers from
turning round the end of the top roller, I provide under this end a stationary
shield. At the opposite end I make in the end frame a notch which freely admits

page_text: the last part of the covering leaf as it is turned in.
At this end I also some-
times arrange a vertical spring punch by depressing which a notch can be cut
in the covering leaf giving its end greater freedom to enter the cavity between
the rollers.

Improvements in Cigar Making Machines.
I, DUKE WILLIAM BULLARD, of No. 49, Queen Victoria Street, in the City
of London, 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 my previous Specification No. 5455 of 1895 I have described a machine
for making cigars by rolling a bundle of tobacco and a leaf or leaves twined over
them in a cavity between a number of rollers all revolving in the same direction
the uppermost roller being mounted in a hinged frame forming a lid which is
opened to give access to the cavity for feeding the tobacco and removing the
finished cigar.
My present invention relates to improvements in a machine of this kind whereby
I render it more rapid and efficient in operation, as I shall describe referring to
the accompanying drawings.
Figure 1 is a plan, Figure 2 is a side view and Figure 3 is a front view of the
machine.
The other figures drawn to an enlarged scale to shew details, are,
Figure 4 a plan partly in section on the line 4-4 of Figure 5 which is a
transverse section on the line 5-5 of Figure 4, and Figure 6 is a part end view
shewing the lid with the upper roller opened up.
On a table T are fixed two end frames F and two intermediate frames f
having bearings for four rollers R and two pinions P and an upper pinion 1.
On the axis of the upper pinion P¹ is pivotted a lid L which has end and intermediate
frames giving bearings for a fifth roller R. Each of the rollers is made in three
parts in length, a cylindrical middle part R having sunk teeth and two tapered
end parts r. Each of these parts has a hole bored longitudinally in its end
and this hole is crossed by a pin. A cylindrical coupler C has mortices cut in its
ends the mortice at the one end at right angles to the mortice at the other end,
and in these mortices are engaged the pins which cross the holes in the ends
of the roller parts. Thus when the middle part of each roller is caused to revolve
the motion is conveyed through the cross pins and the couplers to the end parts
causing them also to revolve. The driving gear may be varied according to the
situation of the machine and its motor, as shewn in the drawings it is as follows:
A prime shaft S driven by any suitable motor drives by bevil gear a counter
shafts a worm on which drives a worm wheel on a shaft M on which there is
a toothed wheel m gearing with the two lowest rollers R. These through the
pinions drive the two side rollers R one of which through the pinion "
drives the roller R. Thus all the rollers are driven at the same speed in the
same direction and as the lid L is pivotted on the axis of the pinion P¹ it and
the upper roller R can be raised or lowered without disengaging the gearing
of R with the roller R. On the axis of 1" is a coiled spring wire W which
urges the lid L to open to the position shewn in Figure 6, giving free access to

page_text: the space between the rollers which can be charged with the tobacco to form the
body of a cigar. The lid L being closed down by hand is held down by its face!
at each end bearing against the end h of a spring catch H, which is pivotted
on the end frame F and has a projecting blade to receive the finger of the
operator. On pressing down both catches H the spring W causes the lid to fly
open.
Under the table T is fixed a rectangular box N fitted with a piston blade n
which can be advanced by a screw worked by bevil gear 9 from a hand wheel Q.
The box N is charged in front of the piston n with paste which by advancing
the piston is caused to rise through a slot t of the table at one side of the machine.
As the leaf which forms the covering of the cigar is drawn in and coiled on the
charge of tobacco while it revolves between the rollers, the end part of the leaf
which is last to be coiled, in passing over the slot receives paste on its lower
face, which when it is wound on the cigar body causes it to adhere to it. For the
better forming of the mouth end of the cigar, a part of the one end frame and
of the lid is conoidally hollowed out at V, giving more freedom for the entrance
and coiling of the last part of the covering leaf.
Each of the rollers, R, instead of being made in three parts in length may
be made in a greater number of parts coupled together as described and these
may be variously shaped to suit the shape of the cigar which is to be formed
by their action
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is: ---
1. In a cigar making machine having rollers each made in parts of its length
the driving connection of these parts consisting of a cylindrical coupler having
mortices in its ends at right angles to each other these ends entering holes
bored longitudinally in the ends of the roller parts and engaging pins fixed across
these holes, substantially as described.
2. In a cigar making machine the gear for driving the rollers consisting of
a toothed wheel driving the two lower rollers a pair of pinions gearing these to
the two side rollers and a pinion gearing one of these to the upper or lid roller
substantially as described.
3. The combination of the lid pivotted on the axis of the pinion which gears
the upper roller to the side roller the wire spring on the said axis and the spring
catches for holding the lid down, substantially as described.
4. In combination with the table and its slot the paste box with its piston and
its advancing gear, substantially as described.
