Improvements in Cigarette Machines and Cigarettes.
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 :-
One part of the present invention relates to that class of cigarette machines in
which the wrapper, in the form of a continuous web, is wrapped around a continuous
filler, and its edges united, after which the wrapper and filler therein are cut into
suitable lengths to form cigarettes.
In machines of this class, the edges of the wrapper have generally been united
by being overlapped and secured by pasting, and difficulty has been found in
drawing and securing the wrapper about the tobacco with sufficient tension to
make the cigarette as solid as desired.
The object of this branch of the present invention is to provide an improved
machine by which a cigarette having a smooth outer surface may be produced, and
the wrapper drawn about the tobacco with sufficient tension to make the cigarette
as solid as desired.
This object is attained by turning the edges of the wrapper inwardly, so as to
form a rib extending longitudinally of the cigarette within the tube formed by the
wrapper, and securing the inwardly-turned edges of the wrapper together, preferably
by pasting and the pressure of suitable guides, the cigarette then being preferably
pressed so as to flatten down the exterior of the seam thus formed. The invention
also includes the cigarette thus produced.
For a full understanding of the invention, a detailed description of a machine
of the preferred form for producing such cigarettes will now be given, in connec-
tion with the accompanying drawings forming a part of this Specification, and the
features of construction forming the invention specifically pointed out in the
claims.
In the drawings

as is necessary to illustrate the application of the present invention thereto.

looking to the left.
Figure 11 is a cross section of the completed cigarette.

Figure 13 is a cross section on a much larger scale, showing a modification.
Figure 14 is a detail plan view of the same.

guides.
Figure 16 is a view similar of Figure 13, showing a modification in the devices
for securing the wrapper; and
Figure 17 is a perspective view of the cigarette of Figure 11.
Referring to said drawings, A is the bed plate or table of the machine which
supports the operating parts, and B the carrying belt by which the wrapper & and
filler v are advanced, the filler passing on to the wrapper from a filler-forming

page_text: mechanism of any suitable form, or being formed by hand. The belt B is carried
by belt rolls 10, driven in any suitable manner, a pulley 11 on the rear roll 10 being
shown for this purpose.
As the wrapper with the filler thereon is advanced by the belt. B, the side edges
of the wrapper are turned upward by external side guides 1, 2, on opposite sides,
and the filler is pressed and compacted by means of grooved roller 12, lying inside
the upturned edges of the wrapper between the guides 1, 2, this roller being
driven by a belt 13, as shown, or in any other suitable manner. In advance of
the pressing roll 12, a bracket with an overhanging arm 14 is mounted on the
bed plate, and carries two internal guides or fingers 3, extending in the line of
movement of the filler inside the guides 1, 2, and turned-up edges of the wrapper,
and gradually converging, as shown in Figure 2, so as to close together at their
forward ends. These guides are preferably formed, as shown, of narrow plates,
resting flatwise upon the filler, as shown in Figures 5 and 6, and extending forward
from the bracket 14, and gradually changing to circular form shown in Figure 7,
as the edges of the wrapper are carried inward between them, and then flattened
vertically, so as to form extended pressing surfaces for pressing the edges together,
as shown in Figures 9 and 10.
It will be understood, however, that the guides need not be of the special form
shown, but converging bars or rods of uniform shape throughout may be used.
The guides 1, 2 are curved inwardly, gradually, over the fingers 3, so as to
bend the edges of the wrapper inward and downward between the guides 3, as
shown in Figures 6, 7, and 8, the side and internal guides acting to draw the
wrapper tight about the filler by the hold upon the inturned edges. When the
edges of the wrapper have been carried inward between the guides 3 into
the position shown in Figure 8, the side guides 1, 2 terminate. The converging
guides 3 are still a short distance apart, and paste is now applied between them,
preferably to both edges, by the pasting device shown in Figures 1, 2, 9, and 12,
and constructed as follows:-Above the fingers 3 is mounted on an arm 15 on the
base plate A, a paste fountain 16, in which runs a thin disc 4, which engages the
paste, so as to take up the latter on its side faces. The edge of this disc 4 lies
between two discs 5, between which runs the paster formed of a thin disc, the side
faces of which receive the paste from discs 5, and transmit it to the edges of the
wrapper between the guides 3, as shown in Figure 9. The disc 4 is driven by
friction from discs 5, and the latter and paster 6 are driven by any suitable means,
being shown as geared together by gears 7, 8, and the shaft of paster 6 as driven
by a belt 17. It will be understood, however, that any other suitable pasting
devices may be used, and that while both edges of the wrapper are shown pasted,
the paste may be applied to but one of the edges, in which case one of the discs 5
will be omitted, and the paster 6 take the paste on but one side.
As the cigarette is advanced from the pasting devices with the edges of the
wrapper pasted as described, the edges are brought together by the guides 3, the
ends of which press the edges together firmly, and thus secure them, as shown in
Figure 10.
The cigarette with its wrapper thus secured may be advanced by the belt B,
and any suitable feeding mechanism coacting therewith, or independent thereof.
There is shown a grooved roller 18 coacting with belt roll 10, and from the shaft
of which the belts 13 and 17 are driven, this shaft being driven by any suitable
means, such as a gear 19, as shown. This roll 18 serves also to press down the top
of the cigarette, so as to flatten out the seam, the cigarette thus formed showing
only a narrow line indicating the seam, or slightly projecting inner rib z, as shown
in Figures 2, 11 and 17.
In the construction thus far described, the edges are pressed together by the
internal guides, under spring pressure produced by the elasticity of the somewhat
long fingers forming the guides. It may be found preferable, however, to use
rollers or similar anti-friction devices for pressing the edges together, and in
Figures 13, 14 and 15, such a construction is shown, in which the guides 3 are

page_text: constructed to form supports a at their ends, and rollers 9 are mounted on vertical
axes therein on opposite sides of the inturned edges, so as to press the edges
together, as the edges pass between them. The supports a are preferably con-
structed as shown, so as to form a plate extending over the filler below the rollers,
thus pressing the filler down, and forming a chamber inside the wrapper for the
rollers. The form of the internal guides 3, in this construction, is the same as in
that previously described, except the ends, where the guides are developed into
the supports for the rollers 9, as clearly shown in Figures 13, 14 and 15. Pasting
devices will preferably be used with this construction, as previously described, but
the edges may be. secured by crimping, indenting, or perforating,-the rollers 9
being suitably formed for the purpose, as shown in Figure 16.
It will be understood that modifications may be made in the construction shown,
without departing from the invention, and it is not to be limited to the specific
form of the devices.

tion, and in what manner the same is to be performed, as communicated to me
