Improvements in Cigar Bunching Machines.
JOSEPH AUGUSTUS CLARINGBURN Machinist Liverpool Street Nottingham do hereby
declare the nature of this invention to be as follows:-

My invention relates to improvements in machines for producing the filler and
binder to form the inner portion of a cigar.
The machine consists of a drum for holding the scrap tobacco secured to the
machine frame. At the bottom of this drum are two discs fastened together and
having perforations in them of such a size that each is an exact measure of the
tobacco required for one filler. Inside the drum there is a stirer which keeps the

tobacco agitated and also assists in filling the perforations in the disc.
also a scraper covering at least one perforation, and placed immediately over the
opening in the bottom of drum, this prevents the quantity of tobacco in the
perforation under it being altered while it is discharged.
The discs are attached to a vertical shaft passing through the bottom of drum, and
have an intermittent rotary motion imparted to them by a ratchett wheel worked by a
lever and pawl from a cam in such a manner that a positive motion is obtained.
On the same shaft as the ratchett wheel are bevil wheels for working the stirer,
which has also an intermittent rotary movement but in the opposite direction to
the discs.
The bottom of the drum is closed with the exception of one opening at the front,
and as the discs inside revolve, the tobacco in each perforation is successively dis-
charged through this opening down a shoot into a hopper.
In my improved machine I have arranged all the mechanism under the drum
thus securing greater compactness in the machine and less liability of injury to the
attendant.
The tobacco passes from the hopper to a tube, the latter is then lowered to the
binder rest and by a plunger in the tube the tobacco is forced out and pressed into
the binder.
In the old machines the tube and plunger are allowed to drop and this arrange-
ment does not ensure certainty of action, but in my improved machine by. the
application of specially designed cams and levers I give a definite motion, and a
definite amount of motion, which latter may be varied to suit different conditions, and
instead of working the tube and plunger by levers and rods fixed over the drum, I
arrange all my mechanism in such a manner that nothing is above, thus allowing
greater facilities for filling and cleaning the drum.
The tobacco in the tube is pressed by the plunger into a binder, laying on the
binder rest, in such a manner that a circular form is given to the filler corresponding
very closely to that of a cigar.
The binder rest consists of a flexible apron rigidly secured at one end of it, the other
end being secured to adjusting screws so that either side may be tightened or
slackened as may be required, in the old style this apron is rigidly secured at both
ends, and can only be altered as a whole. On one or both edges of the apron is a
frill to prevent the tobacco being rolled out at the cigar ends.
Under the apron is a suitable roller, taper by preference, carried in a frame. When
the filler has been pressed into the binder, the tube and plunger ascend, the frame with
its roller is brought forward, and at the same time a lifter under the binder rises and
presses it to the roller and remains in this position during the rolling of the cigar.
The horizontal movement of the frame and roller across the table winds the binder
round the filler and the whole is delivered at the end of the rolling table into a suitable
receiver, from which the cigar bunch or interior portion is taken by the attendant and
finished in the ordinary manner.

page_text: The apron and rolling table may be straight or curved in plan, the latter shape is
used for producing a taper cigar, and the motion of the roller frame is straight or
curved to correspond with the shape of the apron and table.
In my improved machine by giving definite motions to the various parts, I am
enabled to turn out a greater number of cigars, with more regularity and better
finish, the machine is less liable to get out of order and it may he turned backwards
if desired for removing any obstruction, a motion impossible with the present style
of machine.

COMPLETE SPECIFICATION.
Improvements in Cigar Bunching Machines.
JOSEPH AUGUSTUS CLARINGBURN Machinist Liverpool Street Nottingham do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
My invention relates to improvements in machines for producing the filler and
binder to form a bunch or the inner part of a cigar.
By giving definite motions to the various moving parts, the machine is enabled to
turn out a greater number of cigars with increased regularity and better finish. The
machine is less liable to get out of order, and may be turned either backwards or
forwards without damaging it or any of its parts.
In order that my invention may be better understood, I have annexed two
sheets of drawings, in which the same letters indicate the same parts in all the
figures.
Fig. 1. is a sectional side elevation of the machine with the left hand side standard
removed to show more clearly the other parts.
Fig. 2. a front elevation of the machine, with the box removed to show the parts
behind.
Fig. 3. a plan showing the binder rest, roller table and apron clip.
Fig. 4. a section of the above.
A. A¹ are the standards of the machine B B₁ the fast and loose pullies for driving
the machine by power, and C a wheel with a handle for turning the machine by hand
when required. To the fast pulley B is secured a spur pinion a geared into a spur
wheel b, which is itself keyed on the cam shaft D. The pulleys B. B¹ and pinion a
are carried on a fixed axle secured to the standard A.
E is a drum for holding the scrap tobacco which is carried by a bracket from the
standards. Inside this drum are perforated dises which serve for measuring the
tobacco required for each bunch. A stirrer which gently agitates the tobacco and
assist in filling the perforations in the discs, also a scraper covering at least one
perforation, it is placed over the discs and in a line with the outlet to the shoot h and
prevents the tobacco in a perforation, being altered in amount or disturbed in any
way while it is passing to the shute.
These parts inside the drum are the same as are used in the old style of machine
and not being part of my invention, I have not shown them on the drawings.
To the bottom side of the perforated discs is attached a hollow shaft, which passes
through the bottom of the drum and is connected to the top wheel of the bevil gear
shown at g. The stirrer is connected to a shaft passing through the hollow disc shaft,
and connected to the bottom wheel of the bevil gear shown at g. There is an inter-
mediate bevil pinion between the two wheels, and by this means the rotation of the
perforated discs and the stirrer is effected in opposite directions. Over the top whee!
of the bevil gear and secured to it is a ratchett wheel d this is worked by a pawl f and
lever e from the can F. It will thus be seen that the motion of the discs and stirrer
is an intermittent rotary one in opposite directions.
After the tobacco leaves the drum it passes down 'the shoot h and is received by the

tube is connected by the lever and a connecting rod to a cain K from which it receives.
its motion. Inside the tube G is a plunger H which is operated from the cam E¹
through the levers m and n. The action of the tube and plunger is as follows:-
After the hopper has received its charge of tobacco, the tube is lowered to a binder
placed ready for it on the binder rest. During the downward movement the tobacco
passes from the hopper to the inside of the tube, the plunger H then descends and
forces the tobacco from the tube at the same time partly compressing it to the shape
required. The tube starts to rise, closely followed by the plunger until both reach
their first position when the cycle is repeated.
R is a stretcher secured to the two standards, and cast with it is the binder rest M,
fastened to which, rest is the rolling table S. I secure great rigidity to this part by
making the binder rest and stretcher in one piece. Over the rolling table S and
hinder rest M is a loose flexible aprons having a frill on one or both sides, this
prevents the tobacco working out at the cigar end during rolling. One end of the apron
is fixed to the table S; and the other held in an apron clip w. This clip is made
with two slots y y' and secured to the stretcher by screws ar³, at the end of each slot
is an adjusting screw z z¹. By unscrewing or and working one of the
screws or either side of the apron can be tightened. or loosened independently of
the other. Under the apron S is a roller u taper by preference, it is carried in a
frame O, and connected to the lever p which works on pivots at g and r. This lever
is operated by the cam N, through the lever Q. vis a binder lifter and is used for
keeping the binder up to the roller during the process of rolling.
The parts I have just described act as follows:-The roller u is at the extremity
of its backward motion, that is nearest the screws a¹, a binder is pressed with the
apron into the binder rest M, the tube G then discharges its tobacco upon the binder
and the roller u starts on its forward movement, the apron is now S shaped one curve
of which contains the roller and the other curve the tobacco, the roller completes its
journey across the table, rolling the binder round the bunch, and delivering the
whole into a suitable clip or receiver from which it is taken and finished in the usual
manner.
The rolling table S may be straight or curved in plan, the aprons and motion of
the roller u corresponding with the shape of the table. The specification describes a
machine for producing one cigar at a time, but by a multiplication of the various
parts, I can make two or more cigars on the same machine at the same time.
I would have it fully understood I do not claim originality for the drum and its
parts, tube and plunger, binder rest and apron, nor the motions of these parts, for I
am fully aware they are in use at the present time.
my said
Having now particularly described and ascertained the nature of
Invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1st. The general arrangment of the parts of a cigar bunching machine, so that
all cams, levers, rods, and other working parts are below the drum.
2nd. The adjustable clip for holding one end of the apron, as and for the purpose
described.
3rd. The design and arrangement of all cams, levers, and rods, so that positive
motions are given to the discs and stirrer inside the drum, to the tube and plunger,
and to the binder roller.
4th. The design and arrangement of all cams, levers, and rods, giving motions
to the discs and stirrer within the drum, to the tube and plunger, and to the binder
roller, so that the machine may be turned in either direction without damaging it or
any of its parts.
