Improvements in Machines for Making Cigarette Mouth-pieces or
Paper Tubes.
1, RICHARD HARVEY WRIGHT; of 18 Broadway, New York, United States of
America, do hereby declare the nature of this invention to be as follows :-
-
The object of this invention is to provide an automatic machine for making
cigarette mouth-pieces or holders from a continuous paper strip cut into blanks of
proper shape, which are to be consecutively supplied on one edge with an adhesive
substance, as required, then wound into the desired form, partially coated with
paraffin or like substance, and ejected from the machine in a finished condition.
To this end the invention consists in a machine comprising the various devices
and combination of parts, as hereinafter more particularly described with reference
to a very convenient form of the machine.
The frame of the machine comprises a table supported on legs or standards in any
suitable and convenient manner. At the rear end of the machine-frame, beneath
the table, are bearings or journal-boxes for a power-shaft carrying a fly-wheel at
one end and provided at the other end with a driving-pulley which is preferably
furnished with any suitable clutch mechanism, actuated by a hand-lever, so as
to permit the driving-pulley to be made fast or loose on said shaft, as required.
The power-shaft also carries a small spur-gear, which meshes with and drives a
large spur-gear, secured to a cam-shaft, supported in suitable bearings beneath
the table or bed in advance of the power-shaft.
Above the rear end of the table, near one side, is a bracket, for supporting a reel
or rotary spindle, on which is placed the roll of paper from which the proper blanks
are to be cut for making the cigarette holders or mouth-pieces. The free end of
the paper roll or strip is carried or drawn between a set of straightening-rollers,
The first of these
supported by a bracket secured to the top of the table.
straightening-rollers is provided with adjustable guide-collars, to hold the moving
roll of paper in proper alignment, and the third roller in the set is vertically
adjustable by means of a slot and thumb-screw to vary the friction on the roll of
paper as may be required to remove creases and make the paper smooth. From the
straightening-rollers the paper strip passes to a pair of feed-rollers, journalled in
bearings above the table. These feed-rollers are provided with small driving-gears
driven by a large gear actuated by a pawl-and-ratchet mechanism, carried by
pivotally-connected levers, which are put in motion by a crank, face-plate, or
eccentric-disc on the cam-shaft. The shaft carrying the before-mentioned large
gear may be supported in halved bearings, movable on a base-plate, secured to the
table, to facilitate adjustment of the gear.
In front of the feed-rollers is an anvil or die-block the top of which is slightly
below the level of the space between the feed-rollers.
To the front of the roller-bearings is secured a clearing-plate, which projects
above the die-block in approximately a horizontal plane. This clearing-plate
comprises an attaching portion or bar, from one end of which extends a downwardly-
projecting neck, carrying a broad plate, the outline of which is approximately that
of the paper blank to be cut. At the other end of the attaching-bar is a down-
wardly and forwardly-projecting neck, formed with a forwardly-projecting wing,
having a downwardly and rearwardly inclined lip.
Between the attaching bar the neck and the wing aforesaid is an opening for the
passage of the paper strip over the wing. Between the front edge of the wing and

page_text: the rear diagonal edge of the broad plate is an opening to permit the passage of the
paper strip beneath the said plate to the space between the clearing-plate and
die-block.
Above the die-block and pattern-gage is suspended a vertically-reciprocating
punch or cutter-head carried by a plunger, moving in a vertical guide-way, formed
in a bracket supported on the machine-table. This plunger and attached cutter-
head are actuated through a lever, fulcrumed to the rear upper portion of the
bracket aforesaid, and pivoted at its rear end to the upper end of a connecting bar
or lever, the lower end of which is pivoted to a lever, fulcrumed at one end on a
fixed transverse rod, supported by brackets, projecting from the supporting frame-
work of the machine. The said pivoted lever carries a small friction-roller, engaged
in the cam-groove or race of a cam-disc, secured to the cam-shaft and by which the
levers just mentioned and connected cutter-head are actuated.
The several knives correspond in inclination and curvature with the form of the
blank to be cut. The first descent of the cutter head upon and around the clearing-
plate cuts the end of the paper strip beneath said plate and thereby nearly forming
a blank, but leaving it integral with the paper strip at one point, so that the
incomplete blank will be fed forward with said paper strip as the cutter-head
ascends. On the next downward stroke of the cutter-head this incomplete blank
will be severed by a forward knife, thus completing the blank and partly
forming another blank on the end of the paper strip. In this operation the
clearing-plate above the blank serves to prevent said blank from rising with the
receding knives. The upper surface of the die-block may be faced with a steel
wearing-plate, secured by screws passed into openings in the top of the die-block.
The upper surface of said black corresponds with the outline of the blank to be
formed.
The block is provided at the bottom with a base-flange, through which it is
secured to the machine-table.
At the front end of the machine is located the mechanism for making from the
blank a paper tube adapted for use as a cigarette-holder or mouth-piece. This
mechanism comprises various devices which will now be described in connection
with the means for operating the same.
In order to effect the manufacture of the paper tubes or cigarette-holders in large
quantities with ease and rapidity, a number of rotary mandrels are mounted in a
rotary support or carrier, of circular form, keyed centrally to a vertical shaft,
having a bearing in a journal box, bolted to the under side of the machine-table.
The said vertical shaft and attached mandrel-carrier are rotated intermittently by
a pawl-and-ratchet mechanism, of any suitable construction, actuated through bent
levers connected by a slotted link, one end of one of the bent levers being pivoted to
the upper arm of a bell-crank, fulcrumed on the fixed transverse shaft or rod before-
mentioned and having its lower arm provided with a friction-roller engaging a cam-
race in a cam-dise carried by the cam-shatt from which the mandrel-carrier is thus
actuated. In order to prevent backlash an ordinary spring-pawl is provided.
The periphery of the rotary carrier is pierced at regular intervals for receiving
steel wearing-collars, that afford bearings for the body portions of rotary mandrels
employed in making cigarette-holders. These mandrels project radially from the
circular carrier, and have a tapering form, small at their outer ends and
enlarged at their rear portions, where they are supported in the periphery of the
carrier.
One dozen mandrels, more or less can be provided. Each mandrel is provided
with a stem or shank, the rear or inner end of which has a bearing in a steel.
wearing-collar, a number of which are supported in an annular projection, depending
from the top of the rotary carrier, near its hub. The said carrier-hub is perforated
radially to receive adjustable thrust-bearings, that are arranged in line with the
several mandrels.
On each mandrel-stem is secured a bevel-pinion, which meshes with a circular
rack or bevel-gear placed loosely around the carrier-shaft beneath the mandrels.
G

page_text: This rack or gear is actuated by a suitable pawl or ratchet mechanism, provided
with means for preventing backlash as usual. The driving-pawls of this ratchet
mechanism are mounted on horizontally-arranged bell-cranks, connected to a lever
which is pivoted to the upper arm of a bell-crank, fulcrumed on the transverse rod,
and having its lower arm provided with a friction-roller, engaged in the cam-race
of a cam-disc on the cam-shaft, whereby the tube-forming mandrels are rotated.
Each rotary mandrel is hollow and provided on its top with a longitudinal slot,
extending to the outer mandrel end. In this hollow mandrel is pivoted a latch or
dog, for gripping one corner of the blank to be formed into a tube or cigarette-
holder. In the enlarged body portion of the mandrel, beneath the rear end of the
dog, is a spiral spring, which expands against the underside of the dog at its rear
end and thereby depresses the forward end of the dog, so as to cause it to enter and
remain within the mandrel. The rear end of the dog is curved upward and projects
through the rear end of the slot, above the mandrel.
paper
When the rotation of the rotary mandrel-carrier has brought a mandrel into
proper position diagonally in front of the die-block the rear end of the dog afore-
said will have been depressed against its spring by a curved, pivoted lever, operated
through a link, that connects with the lever for actuating the cutter-head. The
forward end of the dog is thus raised out of the slot and above the mandrel. The
movements of the machine are so timed that at this moment, while the dog remains
elevated, the forward edge of the incomplete paper blank, at the corner nearest the
outer end of the mandrel, is passed by the action of the feed-rollers beneath the
raised dog, and at the next downward stroke of the cutter-head the knive severs
the blank from the paper strip, as before explained. Simultaneously with the
descent of the cutter-head the lever releases the dog which is immediately acted
upon by its spring so as to cause it to press the forward edge of the blank into the
slotted mandrel and hold it securely. The descent of the cutter-bead carries with
it a presser-foot attached to the severing knife, and this presser-foot forces the rear
edge of the paper blank into contact with a paste-roller, which is supplied with a
suitable adhesive substance, as hereinafter explained. The bevel-gear mounted
loosely on the carrier shaft now makes one-third of a turn to the right and through
its pinions gives four revolutions to the mandrels, thereby winding the blanks
thereon. At the same time the revolving mandrel-carrier makes one-twelfth of a
turn to the left, thereby bringing another mandrel diagonally in front of the die-
block, to receive a blank, as before described. The movement of the carrier and
gear in opposite directions continues in this manner, and the rotating mandrels,
with attached blanks are carried over and in contact with an adjustable spring-
guide or lower presser-arm, provided with a hook-shaped end, having a convex
surface, against which the paper blanks are pressed in succession by the movements
of the mandrels as they pass over said convex surface and beneath an upper presser-
bar, whereby the paper blanks are kept closely wound on the mandrels until the
paste or adhesive substance on their outer edges has dried. The said upper presser
bar is approximately circular in form, and extends nearly around the mandrel-
carrier. This presser-bar is provided with radial arms connected to a hub, that
rests loosely on the hub of the mandrel-carrier, so as to be capable of yielding
slightly; but in order to prevent the presser-bar from turning with the carrier, a
As the revolution of the
stop is provided in line with one of the radial arms.
mandrel-carrier continues, the mandrels and blanks wound thereon are made to pass
over a sponge or other absorbent substance, saturated with melted wax or paraffin,
with which the tips of the mouth-pieces are thus coated to prevent them from
sticking to the lips of the cigarette-smoker. The sponge is placed in a receptacle,
having a perforated partition, that separates the sponge from the wax or paraffin,
which can be kept in a melted condition by means of a gas-jet connected with a
supply-pipe, or a lamp may be used, if preferred.
In a modification of this device, in lieu of the brush or sponge for applying the
paraffin to the tube, I provide a small roller which revolves on its own axis in the
paraffin bath and applies the paraffin to each tube as the same passes the roller.

page_text: 1 also provide, for cooling the tubes after the paraffin has been applied as above
described, an air blast arrangement consisting of a fan or blower and an outlet pipe
for the air. Said outlet pipe is divided into a number of branches, each of which is
directed to one of the tubes.
When one revolution of the rotary mandrel is about two-thirds completed, the
mandrel that was first supplied with a paper blank arrives opposite a receiver or
"pull-off" that comprises two telescopic tubular parts, one of which is firmly
secured to a horizontal slide, movable on a dove-tailed or ribbed guideway, which
is formed on or supported by an angle-block, adjustable on the machine-table by
means of slots and set-screws so as to enable the pull-off to be adjusted to or from
the mandrel-carrier. To the said slide is attached a horizontal arm, which passes
through a slot in the ribbed guideway and connects with a lever attached at one end
to the rigid horizontal arm and at the other end to a lever, mounted securely on the
upper end of a vertical spindle, which is provided at its lower end with a rigid arm,
that connects with the upper arm of a bell-crank having on its lower arm a friction-
pulley, that engages a cam-race, in a cam-disc, on the cam-shaft, thus providing
means for actuating the pull-off from said cam-shaft.
The tube composing the inner end of the "pull-off" or "receiver" is of larger
diameter and less length than the tube which constitutes the outer end of said
device. In each side of the larger tube at its inner end, is a rectangular opening,
to afford a clearance for the mandrels as will be presently explained. This tube
also has an open-ended slot, in its top, a spring that covers said slot and projects
beyond the inner end of the tube and an internal annular shoulder, cut away centrally
on each side to permit the passage of spring-hooks on each side of the other tube. To
the outer end of the tube moreover, is attached a forwardly-projecting guide-rod
for a spiral spring, that is supported thereon. The smaller tube is formed at its
inner end with a flange or collar, to engage the annular shoulder in the larger tube.
On its top it is provided with a stop or bearing for the outer end of the spiral spring
of the larger tube and at its bottom it has à longitudinal slot, which corresponds
with a similar slot in the bottom of the larger tube for passage of an, ejector or
wire, that is arranged to remove the finished tubes from the pull-off or receiver.
It will be seen that the larger tube is supported loosely on the smaller tube, and
that the guide rod, spiral spring and stop, together form a yielding connection
between these two tubes comprising the pull-off and receiver for the finished mouth-
pieces. This pull-off or receiver is reciprocated along the guideway by means of
the operating devices connecting with the cam-shaft as already explained.
The various parts of the machine are so arranged and timed that the pull-off,
which has moved outward along the guideway in removing a finished mouth-piece or
tube from a mandrel, will return in season to inclose the next mandrel and its attached
mouth-piece which have meanwhile been brought into proper position by the
revolving mandrel-carrier. As the larger tubular portion of the pull-off moves
inward around the mandrel and into contact with the wearing collar thereof, the
spring of the larger tube will bear on the rear upwardly-turned end of the dog or
latch, depressing the same against the action of the spring of the dog and causing
the forward end of the dog to rise slightly in the mandrel-slot, thereby disengaging
the dog from the inwardly-turned lip or corner of the paper-blank at the tip of the
mouth-piece. When the inner end of the larger tube comes in contact with the
wearing collar, its movement is of course arrested, but the smaller tube, carried
by the slide, continues to move inward within the larger tube until the spring
hooks or catches pass behind and engage the enlarged end of the mouth-piece. In
this inward movement of the latter tube the spiral spring of the former tube is
compressed, and as the said smaller tube recedes, carrying with it the mouth-piece
or cigarette-holder, the tension of this spring exerts a pressure on the larger tube
to hold it in place with its spring bearing on the rear end of the dog until the
cigarette-holder has been nearly withdrawn from the mandrel. By this time the
collar of the smaller tube will be in contact with the annular shoulder, and both
fubes thus connected will move off together and withdraw the cigarette holder

page_text: completely from the mandrel. The dog, relieved from the pressure of the actuating
spring, returns to its normal position under the action of the dog spring, and the
mandrel-carrier makes a partial revolution to bring another mandrel into position
for the action of the pull-off. The openings in the sides of the larger tube afford a
clearance for the mandrel, so as to prevent any liability of interference between the
pull-off and rotary mandrel-carrier in their respective movements. The slot in the
top of the larger tube enables the rear upwardly-projecting end of the dog to come
under the action of the actuating spring, and the notches or recesses in the sides of
the annular shoulder permit the hooks or catches to carry the removed mouth-
piece well into the pull-off or receiver.
Each successive cigarette-holder or mouth-piece removed by the pull-off is
telescoped in said pull-off or receiver with the holder or mouth-pieces previously
removed, until the smaller tube contains, say, five telescoped or nested mouth-
pieces. After the pull-off has thus received, say, five mouth-pieces or holders, and
as it moves inward to take off another, the ejector-rod is moved upward into the
slot at the rear end of the line of telescoped mouth-pieces, thereby obstructing their
return with the smaller tube and causing them to drop from the outer end of said
tube into any suitable receptacle.
The ejector is carried by a lever that is pivoted to the table and depressed by a
spring attached to the table. On the underside of the ejector-lever is a projection,
that rests on a cam carried by a shaft, mounted in bearings beneath the machine-
table. The said shaft is rotated through a sprocket-gear, driven by a chain belt
from a sprocket gear mounted on a short shaft beneath the machine-frame. This
short shaft is driven through a spur-gear from a pinion on the main cam-shaft and
thereby actuates the ejector cam through the intermediate mechanism to cause it to
elevate the ejector-rod at proper intervals. To tighten the chain belt and hold it in
position, a flanged idler is provided as usual.
""
The paste-roller is journalled in a hinged bearing so as to enable it to have a
yielding contact with the supply-roller which is mounted on one end of the shaft at
the side of the machine-table and beneath the paste-roller. This supply-roller
revolves in a suitable receptacle, containing paste or other adhesive material, and a
"doctor
or scraper, is provided to spread the adhesive mixture evenly on the
supply-roller.
The paste-receptacle and the paraffin-receptacle with its heating device may be
mounted on vertically-adjustable stands and these standards can be either separate
from the machine-frame or made a part thereof, as preferred.
The machine is automatic in all its operations, and is capable of rapidly
producing large quantities of tapering tubes or holders, completely finished and
ready for the trade.

Improvements in Machines for Making Cigarette Mouth-pieces or
Paper Tubes.
I, RICHARD HARVEY WRIGHT, of 18 Broadway, New York, United States of
America, 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 aud
by the following statement :-
The present invention relates to an automatic machine for making cigarette
mouth-pieces or holders from a continuous paper strip cut into blanks of proper
shape, which are to be consecutively supplied on one edge with an adhesive

page_text: substance, as required, then wound into the desired form, partially coated with
paraffine or like substance, and ejected from the machine in a finished condition.
Although the improvements hereinafter described and claimed, relate to the
devices and means for supplying adhesive substances to one edge of the blank and
for applying paraffine or like substances to the mouth-pieces, and the method and
means for cooling and hardening the same, it is considered desirable for the
clear understanding of these to give a general description of the machine as
illustrated in the drawings.

The frame of the machine comprises a table, 1, supported on legs or standards 2
in any suitable and convenient manner. At the rear end of the machine-frame,
beneath the table 1, are bearings or journal-boxes for a power-shaft, 3, carrying
a fly-wheel, 4, at one end and provided at the other end with a driving-pulley, 5,
wbich is preferably furnished with any suitable clutch mechanism, 6, actuated by
a hand-lever 7, so as to permit the driving-pulley to be made fast or loose on said
shaft, as required. The power-shaft 3 also carries a small spur-gear 8, which
meshes with and drives a large spur-gear, 9, secured to a cam-shaft, 10, supported
in suitable bearings beneath the table or bed 1 in advance of the power-shaft.
in
Above the rear end of the table 1, near one side, is a bracket 11, for supporting
a reel or rotary spindle, 12, on which is placed the roll of paper 13, from which
the proper blanks are to be cut for making the cigarette-holders or mouth-pieces.
The free end of the paper roll or strip 13 is carried or drawn between a set of
straightening-rollers, 14, supported by a bracket 15, secured to the top of the
table. The first of these straightening-rollers 14 is provided with adjustable
guide-collars 16, as shown in Figs. 2, 3, and 5, to hold the moving roll of paper
proper alignment, and the third roller in the set is vertically adjustable by means
of a slot and thumb-screw, 17, as shown in Fig. 1, to vary the friction on the roll
of paper as may be required to remove creases and make the paper smooth. From
the straightening-rollers 14 the paper strip 13 passes to a pair of feed-rollers, 18,
Fig. 5, journaled in bearings 19 above the table. These feed-rollers are provided
with small driving-gears 20, Fig. 1, driven by a large gear, 21, actuated by a pawl-
and-ratchet mechanism, 22, carried by pivotally-connected levers 23, 24, which are
put in motion by a crank face-plate, or eccentric-disk, 25, on the cam-shaft 10.

page_text: The shaft 26 of the gear 21 may be supported in naived bearings 4
a base-plate 28, secured to the table, as shown in Figs. 2, 3, and 5, to facilitate
adjustment of the gear.
In front of the feed-rollers 18 is an anvil or die-block 29, the top of which is
slightly below the level of the space between the feed-rollers.
To the front of the roller-bearings 19 is secured a clearing-plate, 30, Fig. 6,
which projects above the die-block 29 in approximately a horizontal plane. This
clearing-plate 30 comprises an attaching portion or bar, 31, from one end of which
extends a downwardly-projecting neck, 32, carrying a broad plate, 33, the outline
At the other end
of which is approximately that of the paper blank to be cut.
of the attaching-bar 31 is a downwardly and forwardly projecting neck, 34,.
formed with a forwardly-projecting wing, 35, having a downwardly and rearwardly
inclined lip, 36.
Between the bar 31, necks 32, 34, and wing 35 is an opening 37, for passage of
the paper strip 13 over the wing 35, and between the front edge of the wing 35
and rear diagonal edge of the plate 33 is an opening, 38, to permit the passage of
the paper strip 13 beneath the plate 33 to the space between the clearing-plate and
die-block.
Above the die-block 29 and pattern-gage 33 is suspended a vertically-
reciprocating punch or cutter-head 39, Figs. 13 and 14, carried by a plunger 40,
moving in a vertical guideway, 41, formed in a bracket, 42, Figs. 1, 3 and 5,
supported on the machine-table. This plunger 40 and attached cutter-head 39 are
actuated through a lever, 43, fulcrumed to the rear upper portion of the bracket 42
and pivoted at its rear end to the upper end of a connecting bar or lever, 44, the
lower end of which is pivoted to a lever, 45, fulcrumed at one end on a fixed
transverse rod, 46, supported by brackets 47, projecting from the supporting frame-
work of the machine. The lever 45 carries a small friction-roller, 48, Fig. 5,
engaged in the cam-groove or race 49 of a cam-disk, 50, secured to the cam-
shaft 10, and by which the levers 45, 44, 43 and connected cutter-head 39 are
actuated.
The form of the reciprocating cutter-head 39 and its attached knives 51, 52, 53,
54 and 55 is shown in Figs. 1, 5, 13 and 14. It will be seen that the several
knives correspond in inclination and curvature with the form of the blank to be
cut, as shown in Figs 16 and 17. The first descent of the cutter-head upon and
around the pattern-plate 33 cuts the end of the paper strip 13 beneath said plate
into the shape shown in Fig. 16, thereby nearly forming a blank, but leaving it
integral with the paper strip at the point 56, so that the incomplète blank will be
fed forward with said paper strip as the cutter-head ascends.
On the next down-
ward stroke of the cutter-head this incomplete blank will be severed on the
line 56 by the forward knife, 51, thus completing the blank 57, as shown in
Fig. 17, and partly forming another blank on the end of the paper strip. In this
operation the clearing-plate 30 above the blank serves to prevent said blank from
rising with the receding knives. The upper surface of the die-block 29 may be
faced with a steel wearing-plate, 58, Fig. 1, secured by screws passed into
openings 59, Fig. 15, in the top of the die-block. As shown in Fig. 15, which
represents a plan or top view of the die-block with the wearing plate removed, it
will be seen that the upper surface of said block corresponds with the outline of
the blank to be formed and that it is provided at the bottom with a base-flange 60,
through which it is secured to the machine-table.
At the front end of the machine is located the mechanism for making from the
blank 57 a paper tube adapted for use as a cigarette-holder or mouth-piece. This
mechanism comprises various devices which will now be described in connection
with the means for operating the same.
In order to effect the manufacture of the paper tubes or cigarette-holders in
large quantities with ease and rapidity, a number of rotary mandrels are mounted
in a rotary support or carrier, 61, of circular form, keyed centrally to a vertical
shaft, 62, having a bearing in a journal-box, 63, bolted to the under side of the

page_text: -
machine-table. The shaft 62 and attached mandrel-carrier 61 are rotated inter-
mittently by a pawl-and-ratchet mechanism 64, of any suitable construction,
actuated through the bent levers 65, 66, connected by a slotted link, 67, one end
of the bent lever 66 being pivoted to the upper arm of a bell-crank, 68, fulcrumed
on the fixed shaft or rod 46, and having its lower arm provided with a friction-
roller, 69, Fig. 1, engaging a cam-race, 70, in a cam-disk 71, carried by the cam-
shaft 10, from which the mandrel-carrier 61 is thus actuated. In order to prevent
backlash an ordinary spring-pawl, 72, Figs. 2 and 4, is provided.
The periphery of the rotary carrier 61 is pierced at regular intervals for
receiving the steel-wearing-collars 73, that afford bearings for the body portions of
the rotary mandrels 74, employed in making cigarette-holders. These mandrels 74
project radially from the circular carrier 61, and have a tapering form, small at
their outer ends and enlarged at their rear portions, where they are supported in
the periphery of the carrier.
One dozen mandrels are shown in the drawings; but it is obvious that a machine
can be made with a greater or less number. Each mandrel 74 is provided with a
stem or shank, 75, the rear or inner end of which has a bearing in a steel wearing-
collar, 76, a number of which are supported in an annular projection, 77, depending
from the top of the carrier 61, near its hub 78, Figs. 7 and 8. The carrier-hub 78
is perforated radially to receive adjustable thrust-bearings 79, that are arranged
in line with the several mandrels..
On each mandrel-stem 75 is secured a bevel-pinion, 80, which meshes with a
circular rack or bevel-gear, 81, placed loosely around the carrier-shaft 62 beneath
the mandrels. This rack or gear 81 is actuated by a suitable pawl or ratchet
mechanism, 82, provided with means for preventing backlash, as usual. The
driving-pawls 83 of this ratchet mechanism 82 are mounted on horizontally-arranged
bell-cranks 84, shown by dotted lines in Fig. 7. These bell-cranks 84 are con-
nected to a lever 85, which is pivoted to the upper arm of a bell-crank, 86,
fulcrumed on the transverse rod 46, and having its lower arm provided with a
friction-roller, 87, Fig. 2, engaged in the cam-race 88 of a cam-disk, 89, on the
shaft 10, whereby the tube-forming mandrels 74 are rotated.
As clearly shown in Fig. 8, each rotary mandrel 74 is hollow and provided on
its top with a longitudinal slot 90, extending to the outer mandrel end. In this
hollow mandrel is pivoted a latch or dog, 91, for gripping one corner of the blank
to be formed into a tube or cigarette-holder. In the enlarged body portion of the
mandrel, beneath the rear end of the dog 91, is a spiral spring 92, which expands
against the under side of the dog at its rear end and thereby depresses the forward
end of the dog, so as to cause it to enter and remain within the mandrel. The
rear end of the dog 91 is curved upward aud projects through the rear end of the
slot 90 above the mandrel.
When the rotation of the mandrel-carrier 61 has brought a mandrel 74, into
proper position diagonally in front of the die-block 29, the rear end of the dog 91
will have been depressed against the spring 92 by a curved lever, 93, pivoted in
the bracket 42 and operated through a link, 94, that connects with the lever 43
for actuating the cutter-head. The forward end of the dog 91 is thus raised out of
the slot 90 and above the mandrel. The movements of the machine are so timed
that at this moment, while the dog 91 remains elevated, the forward edge of the
incomplete paper blank, Fig. 16, at the corner nearest the outer end of the mandrel,
is passed by the action of the feed-rollers 18 beneath the raised dog 91, and at the
next downward stroke of the cutter-head the knife 51 severs the blank 57 from the
paper strip, as before explained. Simultaneously with the descent of the cutter-
head the lever 93 releases the dog 91, which is immediately acted upon by the
spring 92, so as to cause it to press the forward edge of the blank 57 into the
slotted mandrel and hold it securely. The descent of the cutter-head carries with
it piece 95, attached to the knife 51, and this piece provides an abutment above
the rear edge of the paper blank 57 to resist the pressure of the paste-applying
stamp 96 which at that instant is brought up from beneath and supplies the

page_text: requisite quantity of adhesive material to the edge of the blank as hereinafter fully
explained. The bevel-gear 81 now makes one-third of a turn to the right and
through the pinions 80 gives four revolutions to the mandrels, thereby winding the
paper blanks thereon. At the same time the revolving mandrel-carrier 61 makes
one-twelfth of a turn to the left, thereby bringing another mandrel diagonally in
front of the die-block 29 to receive a blank, as before described. The movement
and
of the carrier 61 and gear 81 in opposite directions continues in this manner,
the rotating mandrels, with attached blanks are carried over and in contact with
an adjustable spring-guide or lower presser arm 97, provided with a hook-shaped
end, 97, having a convex surface, against which the paper blanks are pressed in
succession by the movements of the mandrels as they pass over said convex surface
and beneath an upper pressure-bar, 98, whereby the paper blanks are kept closely
wound on the mandrels until the paste or adhesive substance on their outer edges
has dried. The upper presser-bar, 98, is approximately circular in form, as shown
in Fig. 3, and extends nearly around the mandrel-carrier. This presser-bar 98 is
provided with radial arms 99, connected to a hub, 100, that rests loosely on the
hub of the mandrel-carrier, so as to be capable of yielding slightly; but in order
to prevent the bar 98 from turning with the carrier a stop, 101, Fig. 2, is attached
to the bracket 42, in line with one of the radial arms. As the revolution of the
mandrel-carrier continues, the mandrels and blanks wound thereon are made to
pass in contact with the periphery of a wheel, 102, which revolves in a
receptacle 103, of melted paraffine or wax with which the tips of the mouth-piece
are coated to prevent them from adhering to the lips of the smoker. The coating
material can be kept in a melted or fluid condition by a gas jet, 104, located under
the receptacle and connected with a supply pipe, 105, or a lamp or other convenient
heating device may be employed. The wheel 102 may be mounted in any
convenient way on the frame which supports the receptacle 103 and may be driven
by pulley 106, fixed to its shaft. After the tips have been coated with the melted
material they are subjected to an air blast for the purpose of cooling and hardening
the coating by the means hereinafter fully explained. When one revolution of the
mandrel 61 is about two-thirds completed, the mandrel that was first supplied with
a paper blank arrives opposite a receiver or "pull-off" that comprises two
telescopic tubular parts, 108 and 109, Fig. 12, one of which (indicated by 109) is
firmly secured to a horizontal slide, 110, movable on a dove-tailed or ribbed guide-
way, 111, which is formed on or supported by an angle-block, 112, adjustable on
the machine-table 1 by means of slots 113 and set-screws 114, Fig. 11, so as to
enable the pull-off to be adjusted to or from the mandrel-carrier. To the slide 110
is attached a horizontal arm, 115, which passes through a slot, 116, in the guide-
way 111 and connects with a lever, 117, as shown in Fig. 11. The lever 117 is
attached at one end to the rigid arm 115 and at the other end to a lever, 118,
mounted securely on the upper end of a vertical spindle, 119, Figs. 2 and 4; which
is provided at its lower end with a rigid arm, 120, that connects with the upper
arm of a bell-crank, 121, fulcrumed on the fixed rod 46 and having on its lower
a friction-pulley, 122, Fig. 5, that engages a cam-race, 123, in a cam-
disk, 124, Fig. 4, on the cam-shaft 10, thus providing means for actuating the
pull-off from said cam-shaft.
arm
The tube 108, composing the inner end of the "pull-off" or "receiver," is of large
diameter and less length than the tube 109, which constitutes the outer end of said
device. In each side of the tube 108, at its inner end, is a rectangular opening, 125, to
afford a clearance for the mandrels, as will be presently explained. This tube 108
also has an open-ended slot, 126, in its top, a spring, 127, that covers said slot and
projects beyond the inner end of the tube, and an internal annular shoulder, 128,
cut away centrally on each side at 129, as shown in Fig. 12, to permit the passage
of spring-hooks 130 on each side of the other tube. To the outer end of the
tube 108 is attached a forwardly-projecting guide-rod, 131, for a spiral spring 132,
that is supported thereon. The tube 109 is formed at its inner end with a flange
or collar, 133, to engage the annular shoulder 128 in the tube 108. On its top it
B

page_text: is provided with a stop or bearing, 134, for the outer end of the spiral spring 132,
and at its bottom it has a longitudinal slot, 135, which corresponds with a similar
slot, 135, in the bottom of the tube 108 for passage of an ejector rod or wire, 136,
that is arranged to remove the finished tubes from the pull-off or receiver.
It will be seen that the tube 108 is supported loosely on the tube 109, and that
the rod 131, spiral spring 132, and stop 134 together form a yielding connection
between these two tubes comprising the pull-off and receiver for the finished mouth-
pieces. This pull-off or receiver is reciprocated along the guideway 111 by
means of the operating devices connecting with the cam-shaft 10, as already
explained.
The various parts of the machine are so arranged and timed that the pull-off,
which has moved outward along the guideway 111 in removing a finished mouth-
piece or tube from a mandrel, will return in season to inclose the next mandrel and
its attached mouth-piece, which have meanwhile been brought into proper position
by the revolving mandrel-carrier. As the tubular portion 108 of the pull-off moves
inward around the mandrel 74 and into contact with the collar 73, the spring 127
will bear on the rear upwardly-turned end of the dog or latch 91, depressing the
same against the action of the spring 92, and causing the forward end of the dog to
rise slightly in the mandrel-slot 90, thereby disengaging the dog from the inwardly-
turned lip or corner of the paper blank at the tip of the mouth-piece. When the
inner end of the tube 108 comes in contact with the collar 73, its movement is of
course arrested; but the tube 109, carried by the slide 110, continues to move
inward within the tube 108 until the spring hooks or catches 130 pass behind and
engage the enlarged end of the mouth-piece. In this inward movement of the
tube 109 the spiral spring 132 is compressed, and as the said tube 109 recedes,
carrying with it the mouth-piece or cigarette-holder, the tension of this spring 132
exerts a pressure on the tube 108 to hold it in place with its spring 127 bearing on
the rear end of the dog 91 until the cigarette-holder has been nearly withdrawn
from the mandrel. By this time the collar 133 will be in contact with the
shoulder 128, and both tubes 108 and 109 thus connected will move off together
and withdraw the cigarette-holder completely from the mandrel. The dog 91,
relieved from the pressure of the spring 127, returns to its normal position under
the action of the spring 92, and the mandrel-carrier 61 makes a partial revolution.
to bring another mandrel into position for the action of the pull-off. The
openings 125 in the sides of the tube 108 afford a clearance for the mandrel, so as
to prevent any liability of interference between the pull-off and rotary mandrel-
carrier in their respective movements. The slot 126 in the top of the tube 108
enables the rear upwardly-projecting end of the dog 91 to come under the action of
the spring 127, and the notches or recesses 129 in the sides of the annular
shoulder 128 permit the hooks 130 to carry the removed mouth-piece well into the
pull-off or receiver.
Each successive cigarette-holder or mouth-piece removed by the pull-off is
telescoped in said pull-off or receiver with the holder or mouth-pieces previously.
removed, as shown in Figs. 10 and 11, until the tube 109 contains, say, five
telescoped or nested mouth-pieces. After the pull-off has thus received, say, five
mouth-pieces or holders, and as it moves inward to take off another, the ejector-
rod 136 is moved upward into the slot 135 at the rear end of the line of
telescoped mouth-pieces, thereby obstructing their return with the tube 109 and
causing them to drop from the outer end of said tube into any suitable
receptacle.
The ejector 136 is carried by a lever, 137, that is pivoted to the table 1 and
depressed by a spring, 138, attached to the table, as shown in Figs. 2 and 3.. On
the under side of the ejector-lever 137 is a projection, 139, that rests on a cam, 140,
carried by a shaft, 141, mounted in bearings 142 beneath the machine-table. The
shaft 141 is rotated through a sprocket-gear, 143, driven by a chain belt, 144, from
a sprocket-gear, 145, mounted on a short shaft, 146, beneath the machine-frame.
This short shaft 146 is driven through a spur-gear, 147, from a pinion, 148, on the

main cam-shaft 10, and thereby actuates the cam 140 through the intermediate
mechanism to cause it to elevate the ejector-rod 136 at proper intervals.
tighten the belt 144 and hold it in position, a flanged idler, 149, is provided,
as usual.
The paste-applying stamp 96 is constructed to receive and carry paste or other
adhesive material and is preferably shaped to correspond with the contour of
the rear edge of the blank to apply a line of paste. It is attached to the free end
of an arin, 150, which is pivoted to the end of bent arm, 151, which in turn is pivoted
at its upper end to block, 152, attached to the table 1. The end of arm 150 farthest
from the stamp 96 is pivoted to one end of rod, 153, whose other end is pivoted to
block 152. The bent arm 151 is pivotally connected near its middle part by rod 154,
to arm 155 of a bell-crank lever which is pivoted at a to the paste reservoir mounted
on the frame of the machine, while its other arm, 156, carries a roller, 157, located
in the path of an oval-shaped cam, 158, fixed to shaft of wheel, 159, which is driven
by a sprocket wheel, 160, on the opposite end of wheel shaft, 161, and by a
chain, 162, which passes over a sprocket wheel, 163, fixed to cam shaft 10, as
specially shown in Figs. 1, 3, 4, 5, and 9. The paste-applying stamp 96 takes its
paste directly from wheel, 164, as it sweeps over its periphery in its passage from
its position forward of this wheel, as shown in Fig. 1, to its position against the
blank 57, as shown in Fig. 5. Wheel 164 is mounted to revolve in a support, 165,
pivoted at 166, which support also carries a roller, 167, and wheel 164 is so located
that its periphery is held in contact by spring, 168, with the periphery of wheel, 159,
which is arranged to revolve in reservoir 169 containing paste or other suitable
adhesive material. A second cam, 170, is fixed to the shaft 161 of wheel 159,
such cam being so shaped that it will strike against the periphery of roller 167
and rock the support 165 backward upon its pivot 166 sufficiently and at the
proper time to permit the stamp 96 to return to its position forward of wheel 164
without colliding with it.
As wheel 159 is
Briefly, the operation of the pasting devices is as follows:
revolved, cam 158 is brought in contact with roller 157 to rock the bell-crank lever
on its shaft at a and force its upper arm 155 backward, and through the various
connections heretofore pointed out, carry the stamp 96 from the position shown in
Fig. 1 to the position shown in Fig. 5, the stamp taking its paste on its backward
movement from wheel 164 which is moved out of its return path. The cams 158
and 170 must be so shaped and located on shaft 161 relatively to rollers 157 and 167,
and the rotation of this shaft must be so timed relatively to the feed of the paper
that the stamp 96 will be carried backward and strike the rear edge of the blank
at the instant it is severed from the paper strip and the wheel 164 be swung out of
its return path. The spring, 171, attached to arm 155 and to the frame of the
machine is expanded as this arin is forced backward, and acts by its contraction to
retract the same and restore the stamp to its first position.
The receptacle 103 containing the coating material and its heating device 104
may be mounted on a stand 172, fixed upon a standard, 173, which is vertically
adjustable in support, 174, by means of set screw 175. The wheel 102, which
revolves in the receptacle 103 and carries the coating material to the mouth-tips, is
also separately and yieldingly adjustable by an arrangement for tilting the shaft of
this wheel upward or downward to bring its periphery nearer or further from the
mouth-tips. This adjustment is effected by cross-pivoting the sleeve, 176, in
which the shaft of the wheel revolves, to its support, and by means of a screw
fixed in the support and passing through an arm, 177, depending from the sleeve
and a nut, 178, the lower end of the arm is forced toward the support and the
sleeve and shaft rock and upon the pivot and the wheel brought nearer the mouth-
tips. A spring, 179, may be interposed between the arm 177 and the support which
will give a yielding pressure to the wheel, as shown in Fig. 5.
It is important to cool and thereby harden the coating of the mouth-tips as
soon as possible after it is applied, and especially before they are removed from
their mandrels and nested together, and for this purpose they are subjected to a

page_text: blast of air which is preferably continued for some time. This is conveniently
accomplished by arranging a tube, 180, directly over the path of the tips as they
are carried on their mandrels 74, from the point where they receive the coating to
the "pull-off" or devices by which they are removed from the mandrels and nested
in the receiver. This tube 180 is provided with several depending nozzles, 181, by
which successive blasts of air are brought in close proximity with the coated tips,
the nozzles being preferably located at points beneath which the tips are momen-
tarily stationary. The air can be forced into pipe 180 through flexible tubes 182
which can be connected to rotary blower or any other suitable device for forcing
the desired quantity of air into tube 180.
From the foregoing description the various steps in the manufacture of paper
tubes for cigarette holders or mouth-pieces will be readily understood and need not
be further explained.
The machine is automatic in all its operations, and is capable of rapidly producing
large quantities of tapering tubes or holders, such as shown in Fig. 18, completely
finished and ready for the trade.
