I, WILLIAM ANDERSON HULSE, of 132 Court Street, Rochester in the State of New
York, United States of America, Machinist do hereby declare the nature of this
invention to be as follows:-
:-
This invention relates to improvements in cigarette, machines.
The paper wrapper employed for enveloping the tobacco filler is in the form of a
strip, of considerable length, and the same is drawn into the machine by the action of
an endless band. The said endless band and the wrapper pass together through a
forming tube, and the tobacco filler is laid upon the wrapper by suitable mechanism
such as has heretofore been made use of, so that the proper quantity is presented as
the wrapper and the belt move along progressively. The edges of the paper wrapper
are then turned upwardly by guides, and the extreme edges thereof are folded over in
such a manner as to interlock. Removably secured spirally curved guiding pieces
are also provided, to roll or coil the edges of the strip spirally upon each other. A
small roiler supported by the guiding mechanism, is arranged within the paper tube
forming the wrapper and is preferably driven by friction, and outside the said tube
there is a second roller or wheel, preferably adjustable, and so arranged in combination
with the inside roller that the edges of the paper wrapper, after they are turned over
or rolled together, are pressed by the said rollers into a flat fold. In consequence of
the surfaces of the inner roller and the outer roller or wheel being corrugated, the fold
of the paper is crinkled in such a manner that the wrapper does not afterwards become
separated but is adapted to remain in a tubular form without the need of paste or
other adhesive material to unite the edges of the paper. The entire operation can be
performed with great rapidity and the paper remain in a dry and uninjured condition.
The cigarette tube as drawn through is cut off into suitable lengths to form the
cigarettes.
By this improvement the continuous wrapper that encircles the tobacco filler has a
flattened seam without the application of adhesive material, the mechanism that
Hattens the seam having one part within the wrapper, and the other part outside of
the wrapper, and the tobacco filler is under sufficient compression as it passes through

page_text: the machine to expand and take up the slack of the wrapper caused by the operation
of the mechanism that flattens the seam. The pressure device inside the wrapper is
separated from the filler space or channel by a wall or partition. The tobacco filler
passes through a tapered chamber having at one side the tapered core or guides for
rolling the edges of the paper together and flattening the same.
In a modification, guides are provided in combination with a groove in the forming
tube to prevent the body of the strip from crumpling or wrinkling.
The continuous paper wrapper preferably passes up from below and around a guide
roller and upon the endless band or belt that gives motion to the wrapper as the
cigarette is formed.

Improvements in Cigarette Machines.
I, WILLIAM ANDERSON HULSE, of No. 132 Court Street, Rochester in the 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:-
The paper wrapper employed for enveloping the tobacco filler is in the form of a
strip of considerable length, and the same is drawn into the machine by the action of
an endless band, and the endless band and the wrapper, pass together through a forin-
ing tube, and the tobacco filler is laid upon the wrapper by suitable mechanisin such
as has heretofore been made use of, so that the proper quantity is presented as the
wrapper and the belt move along progressively, and the edges of the paper wrapper
are turned upwardly by guides, and then the extreme edges are folded over in such a
way as to interlock, and there is a small roller supported by the guiding mechanism
and within the paper tube forming the wrapper, and outside thereof there is a second
roller or wheel, so that the edges of the paper wrapper, after they are turned over or
rolled together, are pressed into a flat fold, and in consequence of the surfaces of the
very small roller and the outer roller or wheel being corrugated, the fold of the paper
is crinkled in such a way that the wrapper does not become separated but is adapted
to remain in a tubular form without the need of paste or other adhesive material to
unite the edges of the paper, thereby the entire operation can be performed with great
rapidity and the paper remain in a dry and uninjured condition, and the cigarette
tube as drawn through is to be cut off into suitable lengths to form the cigarettes.
By this improvement, the continuous wrapper that encircles the tobacco filler has a
flattened seam without the application of adhesive material, the mechanism that
flattens the seam baving one part within the wrapper, and the other part outside of
the wrapper, and the tobacco filler is under sufficient compression as it passes through
the machine to expand and take up the slack of the wrapper caused by the operation
of the mechanism that flattens the seam, and the tobacco filler passes through a
tapered chamber having at one side the tapered core or guides for rolling the edges
of the paper together and flattening the same.
The continuous paper wrapper preferably passes up from below and around a guide
roller and upon the endless band or belt that gives motion to the wrapper as the
cigarette is formed.
In the drawings Fig. 1 represents a view in perspective of my improvements

page_text: attached to the frame of a cigarette machine. Fig. 2 represents a longitudinal
section of the saine between the lines x and y of Fig. 1. Figs. 3, 4, 5, 6 and 7,
represent cross sectional views on the line 1, 2, 3, 4, and 5 respectively, of Fig, 2,
showing the position of the various parts at those points as the wrapping strip and
the tobacco filled deposited thereon are advancing. Fig. 8 is a section of a modified
construction through the line 5 of Fig. 2. Fig. 9 is a view in perspective of the
device for folding or coiling the edges of the wrapper strip.
By reference to the figures of the drawings, A represents a tube through which the
tobacco filler and the paper wrapping strip B are advanced or fed, and by means of,
which the paper strip is gradually brought from a flat into a tubular shape to encircle
or surround the tobacco filler. This tube is shown as attached to a cigarette machine
by any convenient ineans, as by a support A¹ and frame O secured to frame ( of the
machine. The tube is conveniently made by forming two nearly semi-circular parts,
the lower part being designated by C and the upper part by D, from sheet metal and
uniting them into a tube adapted to form a channel or passage way B₁ through which
a tobacco filler and a wrapping strip are advanced simultaneously, the wrapping strip
being gradually brought from a flat into a tubular form to completely encircle or
surround the tobacco filler.
The parts C and D are secured together by means of solder or brazing, or connect-
ing bands or pieces, in such manner as to leave slits or openings a, a between the
parts C and D through which the edges of the wrapping strip and endless band E can
project. The lower part C projects rearwardly beyond the part D and gradually
recedes from a semi-cylindrical into nearly a flat shape, and its edges are folded over
to form guides b, b for the edges of the paper strip, these guides preferably extending
somewhat beyond the junction of the parts C and D to or near the beginning of the
slits a, a.
The rear end of the part C is provided with a friction roller F, over which
the paper strip and the band E pass. This roller is journalled in side pieces c secured
to the edges of the part C and on the upper face of which is a passage way for the
band E and upon its under face a similar way for the paper strip. After passing over
the roller F, the band E passes underneath the part C till it reaches an opening H cut
through the wall of part C where it enters the tube A. The paper strip passes over
the roller Fabove the band. E and enters the rear end of the part C, its edges lying in
the guides b, b, and as it is advanced it is gradually brought into semi-circular shape as
it enters the mouth of the tube and is there brought in contact with the upper
surface of the band E. The band E passes through the tube and over a pulley I
located beyond the forward end of the tube and journaled in attachments to the frame
of the machine, and operates to advance or draw the paper strip and the tobacco filler
deposited thereon through the tube, and beyond its forward end, if desired.
The parts C and D are preferably tapered so as to form a tapered or gradually con-
tracted space or channel B¹ through the tube A for the purpose of compressing the
tobacco filler to such degree that as it passes out from the forward end of the part D
and the pressure is released therefrom, it will expand sufficiently to fill the sealed
wrapper. The part C preferably extends beyond the forward end of the part D and is
preferably formed into a tube J through which the band E and the cigarette cylinder
are passed.
As the strip of paper carrying the tobacco is advanced through the tube A by means
of the continuous movement of the band E, it is gradually wrapped or folded into
tubular shape, and its opposite edges, together with the edges of the band, having
passed out through the slits a, a, are gradually brought towards and into engagement
with each other upon the outer surface of the part D, and are secured together to form
a seam laid down flat upon the body of the wrapper without the application of paste
or other adhesive material.
In the drawings K is a projection secured to the upper surface of the tube, and on
either side thereof are secured at their upper edges thin metal strips d, d whose lower
edges and forward ends are free or unsecured. The under surfaces of these strips
conform substantially to the upright surfaces of the projection K and the upper
surface of the part, D, but the strips are so arranged relatively to these surfaces that

page_text: narrow guideways are formed for the edges of the paper strip and the hand E. These
strips are preferably slightly elastic at their lower edges and forward ends and are
arranged to hold the edges of the band and the paper strip in close contact with the
surface of the part D. The portion of the projection K between the strips d, d is
thinned away till it terminates in a knife edge which permits the edges of the paper
strip to come in contact with each other, as shown in section in Fig. 4 of the drawings.
Thé edges of the paper strip being now in contact with each other, enter a device L
secured to the projection K in which they are gradually folded or rolled upon each
other to give the necessary number of thicknesses of paper for the seam. The device I
is conveniently made by bending two strips e, e of thin metal spirally and securing
their rear ends to a supporting block or piece M in which they are contained, so as to
form a narrow channel between the strips for the passage of the upper edges. As the
paper passes through this channel, the edges are folded or coiled to such an extent
that when they emerge into the small tapered chamber F the coiling will be continued
according to the length and taper of the chamber. The exit from this chamber
should be small enough to consolidate the several thicknesses of folds of paper into a
compass to give a seam of the desired size. The piece M is made separate from the
projection K and is removably secured thereto by inserting it into dovetailed or other
notches cut through the projection, the upper edge of the piece M being corres-
pondingly notched to prevent any longitudinal movement. The piece M is shown in
perspective in Fig. 9 of the drawings.
The engaged edges of the wrapper as they emerge from the mouth of the tapered
chamber pass directly to a pressure device in which they are secured together to
form a seam without the application of paste, and this seam is pressed down flat so as
to conform to the body contour of the finished cigarette as seen in Fig. 10 of the
drawings. The pressure device is composed of two main operative parts, one part
having a wheel N journaled in a piece N¹ arranged to slide in suitable ways in a
frame O secured to the main frame O¹ of the machine and driven by a pulley P (as
seen in Fig. 1) which pulley is in turn driven by a cross belt P1 which passes over a
positively driven pulley I, over which the band E passes and by which it is driven (as
seen in Figs. 11 and 12), the size and arrangement of the parts being such that the
periphery of wheel N is caused to travel at the same speed as the band E, und conse-
quently the paper strip B is advanced through the pressure device at the same speed
with the periphery of the wheel N which bears upon its edges. The pulley I is driven
by a bevelled gear R attached to its shaft which meshes with a corresponding driving
gear. The second part of the pressure device, as shown in the drawings, is a small
roller Qjournaled in the walls of a recess formed in the upper surface of the part I).
The shaft of this roller is arranged at right angles to the line of the advance of the
wrapper and filler, and the face of the roller is directly in the path of the folded
edges of the wrapper, so that such edges will pass over the face of the roller, and the
roller is revolved by the friction or pressure of the opposing parts. The periphery of
the wheel N is arranged to bear directly over the face of the roller Q, and this wheel is
preferably adjustable by means of a screw g passing through the top of the frame
and connected with a spring h in such manner that the piece N₁ carrying the wheel N
and the pulley P can be moved up and down to bring the desired pressure upon the
seam, the spring h operating to accommodate for any variations in the thickness of
the seam. The periphery of the wheel N is serrated or roughened in any desired
manner, so that as it is forced down upon the engaged edges of the wrapper and the
pressure is resisted by the surface of the roller Q located within the wrapper and
operating as an anvil to resist the pressure of the wheel N, the engaged edges of the
wrapper will be pressed into close contact and will be indented and incorporated or
er.bodied into each other sufficiently to form a strong and reliable sean, without the
application of paste or other adhesive material, to hold the tobacco filler in place and
to resist any pressure which may result from the expansion of the filler when released
from pressure, the position of the parts when the wrapper edges are pressed together
to forin the flat seam, is shown in Figs. 7 and 8, in which it is seen that the advancing
tobacco filler is encircled or surrounded by the advancing wrapper, and that one of the

page_text: pressure devices, the wheel N, is located outside of the wrapper to give the necessary
pressure, while the other part, the roller Q, is located within the wrapper to resist the
pressure of the wheel N, and that the engaged wrapper edges piss between the pressure
producing and pressure resisting parts, and are incorporated into a finished seain which
is flattened down upon the body of the wrapper. It is also seen that at this point the
tobacco filler space or channel B is within the wrapper and that this space or channel
is occupied by the filler when the wrapper seam is formed and laid down upon the
body of the wrapper, and that a two-part pressure device, one part operating outside
of the wrapper and the other operating inside thereof, is essential to accomplish this
result.
It is observed that instead of the roller Q, the smooth plain surface of the part D
may be used for the anvil or resisting part of the pressure device, as shown in Fig. 8
of the drawings, and that in such construction no enlargement of the part D would be
required to seat the roller Q. The roller, however, as it moves under pressure with
equal speed with the wheel N greatly reduces the liability of tearing the paper as it
is advanced.
The tobacco filler should be sufficiently compressed so that when it passes from
under the forward end of the part D and is released from pressure, it will expand to
fill the wrapper and produce a smooth cigarette, and this can be readily effected by
giving the proper taper to the tubular channel B¹. It is remarked that the diameter
of the roller can be made very small as compared with the diameter of the filler
space or channel B', and consequently, but little expansion of the tobacco filler will be
required to take up the slack and completely fill the cigarette wrapper.
When the completed cigarette cylinder has passed beyond the end of the tube A, it
may be delivered to a cutter and severed into smokeable lengths by any suitable
mechanisın.
In the mechanism heretofore specifically described and shown in Figs. 1 to 10
inclusive of the drawings; the edges of the wrapping strip are turned outward and
rolled over outside of the body of the wrapper, and the seam is compressed down on
the outside of the wrapper. By slight changes or modifications in the construction,
the wrapper edges are turned inwardly and the seam is formed within the wrapper
and is pressed against its interior surface.
These modifications are shown in the drawings in Figs. 11 to 17 inclusive, Fig. 11
and 12 being longitudinal sectional and plan views, Fig. 13 an enlarged longitudinal
sectional view of the part included between the lines z, z of Fig. 12, and Figs. 14, 15,
16 and 17 being cross sections on the lines 6, 7, 8 and 9, respectively, of Figs. 12
and 13, in which is represented substantially the same construction as heretofore
particularly described, with the exception of devices for turning the edges of the
wrapping strip B inwardly relative to the body of the wrapper and forming the seam
on the interior thereof, and, consequently it is considered necessary to describe only
these devices.
In these figures of the drawings, i is a longitudinal groove or depression formed on
the upper surface of the part D of the tube A; jj are strips of thin metal con-
forming to the upper surface of the tube and secured thereto at their rear
ends, their forward ends being left free or unattached. The upper edges k of these
strips, at their forward ends, are turned downward in the groove i and the strips are
preferably so constructed that their forward ends will press downward upon the surface
of the tube, but will easily spring upward and outward to permit the passage of the
edges of the paper strip and the band E, between them and the surface the tube, as
seen in Fig, 14. The function of these strips is to guide the edges of the paper and
turn them downward into the groove i as the strip is advanced through and along the
tube, and as the edges are turned downward, to prevent the body of the strip from
crumpling or wrinkling. After the edges of the paper strip have passed the forward
ends of the srips jj, they are advanced to the downward projections m, secured to the
part C, as shown in Fig. 15, and are still further turned downward toward the center
of the tube, and as they pass the last of these projections, they are brought in contact
and pass into a slit o opening into a guide-way formed on the top of the tube, in

page_text: which is located a strip of metal n curved around a small core p, secured to the wall
of the guideway, by which the downwardly projecting edges of the strip are gradually
rolled or coiled upon each other and partly around the core p, as shown in Figs. 13
and 16. The free end of this core is tapered and projects into a tapered chamber r
whose exit is near the pressure wheel Q, and as the parily coiled edges are advanced
along the tapered ends of the core and to the exit of the chamber, they are still
further rolled or coiled together to produce the desired number of thicknesses of paper
for the seam, as shown in Fig, 17, and are delivered to the pressure device. The con-
struction, arrangement and operation of the pressure device by which the engaged edges
of the paper strip are compressed together and are incorporated and embedded into a
sealed seam without the application of paste or other adhesive material, which seam
is flattened down upon the body of the wrapper, are substantially the same as
heretofore fully described and shown.
As I am, as far as I am aware, the first to devise means to produce a continuous
or long cigarette having a longitudinal wrapper seam forned without the application
of paste, and laid down to coincide with the body of the cigarette, I do not wish to
limit my iuvention to any special means or mechanism for advancing or feeding the
tobacco filler and wrapping strip to the seam forming mechanism, or to any special
devices for wrapping the strip of paper around the filler, or to any special devices for
bringing the edges of the wrapping strip into engagement with each other to form the
necessary thickness of paper for the seam, as all these operations are old, and can be
carried out by a great variety of well known devices and mechanisms. My invention
relates, essentially to the sealing of the wrapper seam, when and at a point where the
wrapper surrounds cr encloses the filler, and the wrapper and filler are advancing
simultaneously, and in such manner and by such devices that no paste or adhesive
inaterial is required to form the seam, and the seam so formed is pressed down flat
so that it will conform to the contour of the body of the finished cigarette, and I wish
it to be understood that any claims are intended to lay claim only to arrangements
in which there is accommodation for the filler passing with the wrapper along the
part of the apparatus whereat the seaming is effected.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
