Improvements in Oigarette Machines.
I PHILIP ARTHUR NEWTON of The Office for Patents, 6 Bream's Buildings,
Chancery Lane in the County of London, Patent Agent, 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 :-
The object of the present invention is to provide an improved apparatus for
manufacturing cigarettes of substantially elliptical form in cross section.
In the accompanying drawings, forming a part of this specification, there are
shewn such parts of a cigarette machine of the preferred form, as are necessary to
illustrate the invention, and a full description thereof will now be given, and the
features of construction forming the invention will then be specifically pointed out
in the claims.
In the drawings:-
Fig. 1 is a diagrammatic elevation of those parts of the apparatus operating
directly on the rod and wrapper, to form the continuous cigarette rod.
Fig. 2 is a plan view of the same.
Fig. 3 is an enlarged side view of the wrapping tube, from the side opposite that
shown in Fig. 1, with the tube partly broken away, to show the construction.
Figs. 4, 5, 6, 7, are cross sections on respectively the lines 4, 5, 6, 7, of Figs. 2
and 3.
Fig. 8 is a perspective view of the cigarette.
The construction shown in Figs. 1 to 7 is similar to that of the well-known
Bonsack machine, and employs a wrapping tube by which the tobacco is moulded
to form a continuous elliptical filler, and the wrapper folded about the filler and
pasted to form a continuous elliptical cigarette rod, which is then cut into cigarette
lengths by any suitable mechanism, the wrapper and filler being carried through
the wrapping tube by a continuous belt, and the tobacco being fed to the wrapping
tube by devices of any suitable form, of which many are now well-known. In the
construction shown, the feeding devices for the tobacco consist of two side belts a,
passing around horizontal wheels A and bottom belt b, passing around vertical
wheel B, these wheels being set at the proper distance apart to secure the partial
compression and advance of the tobacco, and a grooved vertical wheel C being
mounted above, and co-acting with the belt b and wheel B, to press down the top
of the tobacco as it is advanced between the wheels A, B, C, this wheel C
preferably being grooved, as shown, so as to curve the top of the tobacco to some
extent, and thus aid in reducing it to elliptical form. These wheels, with the belts,
may all be driven by any suitable means, such as are well known, and require no
illustration. The tobacco is advanced by the wheels and belts above described
between guides d to the wrapping tube D, which is supported in any suitable
manner, just above, and in advance of, the bottom belt b, and through which
wrapping tube runs the continuous belt e, carrying the wrapper x, with the tobacco
filler thereon, through the tube, to form the continuous cigarette X.
The wrapping tube D is shown as having, at its rear end, the usual curved
support 10, over which the tobacco and wrapper are advanced to the bottom, or
trough plate 11, and having the usual side guides 1 for the opposite edges of the

page_text: wrapper. Above the curved trough plate 11, on which the belt supports and
carries the wrapper with the tobacco thereon, is suspended, by arins 3, as usual in
such constructions, plate 12, narrower than the trough formed by the plate 11, 80
that the edges of the wrapper and belt may run between the plates 11, 12, and
this plate 12 is inclined so as to compress the tobacco, and the two plates 11, 12
formed so as to mould the tobacco to a filler of substantially elliptical form in
cross section, as shewn in Fig. 4, the top plate 12, at this point, having a flat curve
on its under face, and the bottom of the trough plate 11 forming a flat curve, as
shown in this figure.
From the end of the plate 12 extends the wrapping chamber, which is formed
by the trough plate 11, and an overhanging flange 13 thereon, the bottom of the
chamber, being formed with a flat curve and the flange 13 having its under face
similarly curved, so as to hold the filler received from the plate 11 in elliptical
form, while at the same time the flange.13 turns dowur one side of the belt with
the wrapper, so as to form an elliptical. wrapper tube enclosing the filler, the
other edge of the wrapper and belt lying against the upturned pasting flange or
abutment 4 on the opposite,side of the tube, as shown in Fig. 5, this upturned edge
of the wrapper being supported and held in proper position for pasting by the
arm 8, as usual, in such constructions, the paste. being shown as applied by a
horizontally rotating. paste wheel E fed by a paste supply wheel F, fed in any
suitable manner, as usual in this class of machines.
Beyond the point at which the paste is applied, the belt and the pasted edge of
the wrapper are turned in by the curve of the flange 4 and the lapping point 5 at
the end of the flange, as usual in such constructions, and the wrapper: closed
completely down by the belt passing under the end 7 of the flange 14 extending
over the trough plate from the side of the tube opposite that at which flange 13
was formed, so as to bring the pasted edge of the wrapper down upon the opposite
edge, just in advance of the point 5, where the flange 13 is cut away to permit it,
and thus close and seal the wrapper, tube, the, unpasted edge of the wrapper being
held in position to form the elliptical wrapper tube, with the elliptical filler therein,
by the flange 13, as shown in Fig. 6. Beyond this point, at which the wrapper
tube closed and sealed; so as to form the complete continuous elliptical cigarette
rod, the flange 14 extends over the top of the trough plate, so as to press the belt
down and hold the cigarette rod in, form, the flat curve.of.the bottom plate 11 being
continued, and the flange 14 having a similar curve, on its under side, so as to form
an elliptical tube, by which the cigarette rod is held under pressure in its elliptical
shape, after the pasting of the wrapper strip, producing a cigarette- rod of per-
manent elliptical form, which cigarette rod is then cut into cigarette lengths by
any suitable cutting devices, such as are in common use, forming cigarettes such as
shown in Fig. 8.
It will be understood that the terin. "elliptical" used herein is not intended to
limit the invention to a cigarette, rod of exactly elliptical form. in cross section,
but is intended to cover any modification of form, so long as it is substantially
elliptical:..
Having now particularly, described and ascertained the nature of the said inven-
tion and, in what manner the same is to be performed; as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. The combination with, means, for feeding.a.continuous row of tobacco, of
plates 11, 12, having their walls curved to convert the tobacco into a continuous
rod elliptical in cross section, and a wrapping chamber having opposite sides
formed with flat curves, to form a continuous elliptical..wrapper tube enclosing
the tobacco rod, and a feeding. belt travelling between said plates and through
the chamber, substantially as; described...
2. The combination with ineans for feeding a continuous row of tobacco, of
