PROVISIONAL SPECIFICATION.
Improvements in Cigarette Mouth-piece Making Machines.
We, THOMAS WHITEHORN, Mechanic, and HENRY NICHOLSON BRADy, Stationer,
both of No. 132, Flinders Lane, Melbourne, in the Colony of Victoria, do
hereby declare the nature of this invention to be as follows:-
This invention has been devised for the purpose of providing improved mechan-
ism or apparatus to be used in manufacturing mouth pieces for cigarettes and
also for coating such mouth pieces; when being so made with a covering of
paraffine. Our improvements may be described as follows;―
Upon a central spindle or shaft is mounted a circular plate, or disc, provided
with teeth at its periphery; such circular toothed plate being driven by a corre-
spondingly toothed wheel into which it gears. The latter receives its rotatory
motion from any convenient source.
Upon the toothed circular plate and near its circumferential line are centred four
mandrels each formed in the following manner. The shank is tapered and
provided with an incut or slit for the reception of the tongue or lip of the piece
of paper to be twisted into the mouth piece. The shank terminates, at its
largest diameter, in a circular butt plate, the said butt plate fitting into a
circular depression in the large circular plate or disc first hereinbefore mentioned.
Oil grooves are also provided for lubrication. At the back of the tapered shank,
and proceeding from said circular butt piece or flange, is a spindle carefully
fitted in a bearing formed in a perforation through the circular plate first afore-
said and, after passing through another similar circular butt piece passes through
and is secured to a toothed pinion wheel, and finally terminates in a screw thread.
Upon this screw is a lock nut and pin, so arranged that, by screwing the nut, the
circular butt plates may be adjusted in their pressure on the circular plate first
hereinbefore mentioned.
The small tooth pinion wheels (that is to. say one at the back of each of
the four mandrels) are arranged to receive rotatory motion from a series of peri-
pheral toothed wheels or segments of wheels, the whole mechanism working in
such a
manner that, as the circular plate first mentioned revolves, the four
mandrels move in a circular direction synchronously with it; but also revolve in
their own independent planes by the action of their driving wheels or segments
of wheels as aforesaid.
Preferably but not arbitrarily we employ four of such mandrels, but we may
vary such number according to local requirements without departing from the
nature of their modus operandi. The pieces of paper, out of which the mouth
pieces are to be coiled or formed, are fed by a slightly adhesive roller on to an
inclined plate; this latter directs or passes them one by one into a slit of one of
the mandrels, timed to arrive opportunely to receive the lip of the piece of
Preferably two of these feeding rollers and inclined plates are employed.
After having gripped the paper piece the mandrel proceeds downward or upward
respectively in its circulatory movement, meanwhile revolving in its own piane
and coiling the paper around itself and an opposite pressure is exerted against
paper.

page_text: the paper by a backing plate or brushes set to the sweep or curve of the circle
described by the rotating mandrels.
Previous to the paper coming into contact with the mandrel a small roller or
pad containing paste or other adhesive medium is brought into contact with a
portion of the paper the result being that while the coiled paper is revolving
around the mandrel, and while the latter is proceeding in its travel of a quadrant
of a circle the sticky matter adheres to the paper at the parts affected and makes
the coil a fixture.
By the time the mandrel has travelled to a quadrant of the circle of its rotation
the paste or adhesive gum has made the paper fast to itself, and at this stage the
last few revolutions of the mandrel in its own plane (with the coiled paper mouth
piece thereon) permits engagement with a small heated sponge pad or wheel con-
taining melted paraffine. The result is that the mouth piece, or as wide a piece
of it as is desired, becomes coated with a film of such paraffine.
At this stage an apparatus which we term a "kicker comes into play. This
kicker is preferably formed of flat spring steel and is sized somewhat after the
manner of a fork to fit closely to the metal mandrel so that when it is projected
forward it meets the increased diameter caused by the thickness of the paper
mouth piece and ejects the latter violently from its position on the said mandrel.
We prefer at this stage to employ a draught of cool air to meet the newly
formed and paraffined mouth piece after it has left the shank, so as to quickly
set the said film of paraffine. The mouth piece thus constructed is finished
and ready for use and may be packed away without further manipulation or
preparation.

We, THOMAS WHITEHORN, Mechanic, and HENRY NICHOLSON BRADY, Stationer,
.both of No. 132, Flinders Lane, Melbourne, in the Colony of Victoria, 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:—
This invention has been devised for the purpose of providing improved mechan-
ism or apparatus to be used in manufacturing mouth-pieces for cigarettes and
also for coating such mouth-pieces, when being so made, with a covering of
paraffine.
In order to make the invention clear in describing same we will make reference to

page_text: Upon a central spindle or shaft 1 having bearing in frame 10 is mounted a
circular plate or disc 2 provided with teeth at its periphery such circular disc 2
being driven by a correspondingly toothed wheel 3 but the teeth of which are
interrupted by a plain portion 121 on the periphery-this wheel gears with the
disc 2--and is set upon a shaft 4 set in suitable bearing blocks 5, 5 (Figure 1)
and receives its rotary motion from any convenient source such as from a pulley
wheel set on it, or by means of a crank handle. Upon the toothed disc 2 and
near its circumferential line is centred a mandrel 6, the mandrel 6 has a tapered
shank and is provided with an incut or slit for the reception of the tongue or lip
of the piece of paper to be twisted into the mouth piece. The mandrel passes
through a circular hole formed in the disc 2 and which has flanges 13, 14 (Figure 1)
encircling it. The back of the mandrel carries a small toothed pinion wheel 7,
lock nuts or stops are provided at 8.on the mandrel. The small toothed pinion
wheel 7 is arranged to receive rotary motion from segmental frame 9 which is
fixed to the standard 10. The segmental frame 9 has a portion 11 with internal
teeth and a portion 12 with external teeth, the flange 14 (Figures 1 and 5) has a
slot in its periphery and a spring 15 affixed to the disc 2 bears in the said slot
and presses against the mandrel to prevent its turning except under pressure.
17 represents a holder for the paper blanks which are to be made into the mouth
pieces. This holder in plan corresponds in form with the shape of the paper blanks
and is supported by a standard 18. The holder is provided with a false bottom 100
(Figure 2) which is arranged to move upwardly during the operation of the
machine so as to maintain the paper blanks at a constant level, this is effected by
means of a screw rod 21 fixed to the false bottom plate and which passes through
a sleeve 20 attached to the bottom of 17. The sleeve supports a ratchet wheel 19
which is turned by spring pawl 22 which is pivotted to an arm 97 (Figure 2) pro-
jecting from a sliding frame 23. This sliding frame is of L shape the horizontal
limb 24 of which slides in a dove-tailed recess formed in a fixed block 25 and has
a slot 96 (Figure 3) which encircles shaft 4. A pin or roller 26 is affixed near
the end of 24 and is arranged to ride upon cam 27 set upon the shaft 4. A
spring 101 is affixed at one end to 24 and at the other end to 25 and serves to
return the L frame against the action of the cam 27. The frame 23 has a dove-
tailed slot in which a vertical plate 29 slides, this plate 29 is bent into suitable
form and carries receptacle 30 which is arranged to hold gum or other suitable
adhesive substance. This box is tapered towards its bottom and which is closed
in by a roller 31. This roller is set upon a spindle 32 (Figure 3) having bearings
in the sides of the receptacle 30 and said spindle carries a small ratchet wheel 33.
A pawl 34 is pivotted to plate 98 supported by standard 18 said pawl engages with
the ratchet wheel so as to turn the roller. A spring 35 is set at the back of the
pawl. The front of the receptacle 30 has a hinged plate 115 and a thumb screw
116 for adjusting the pressure of same against roller to regulate the flow of gum.
The box 17 aforesaid has its back plate 36 hinged at the bottom to the box
and carries an arm 37 (Figure 3) which projects upwardly. The box 30 in its
movement (hereafter described) comes in contact with the said arm 37 so as to
turn the back plate on its hinge and so release its pressure from the paper
blanks 102 and make room for the roller. A spiral spring 38 is connected at
one end to the side of box 17 and at the other end to back
plate 36 to return same when pressure is released. Vertical motion
is given to the plate 29 (Figure 3) and box 30 by means of a rod 39 connected
with it and passing down to a rocking lever which latter is pivotted at 40 to
fixed block 25. The rod 39 engages with and slides upon the arm 41 of said
lever the opposite arm 42 terminates with roller 43 which rides upon a cam 44
set upon the shaft 4.
The toothed wheel 3 aforesaid has an annular rim 46 (Figure 2) upon it which
extends about two thirds around it and forms with the central portion 47 a
groove 48, the edges of the said rim 46 being tapered off. A roller 49 set at the
end of plate 50 is arranged to enter and travel through the said groove.

This

page_text: plate 50 is pivotted at its bottom to fixed frame 51 and has a spring 52 set
beneath it to exert an upward pressure. At the top of the plate 50 a pin 53
(Figure 2) is set and projects upwardly and is arranged to enter a hole formed in
tapered strip 54 (four of which are set upon the disc 2 at its back)-the strips 54
with the plate 50 serve to lock and hold the disc while the wheel 3 is out of gear
with 2. An arm 55 (Figure 2) is pivotted to the framing 10, its other end
engaging with cam 56 on shaft 4. A rod 57 rests upon the said arm 55: This rod
works in fixed guide 58 and carries bent frame terminating in rack bar 59.
This rack bar is arranged to engage with pinion 60 having bearing in standard
117. The pinion 60 is intimately connected with toothed segment 61, and which
is arranged to gear with pinion 7 as hereafter described. A spring 103 is provided
to return the parts after action.
To the front of the disc is secured a block 03 (Figures 1 and 6) which form a
bearing for a spindle 64 which has at one end spokes or radial arms 65, 66 the
other end being provided with a head or block 67 which lies between the backing
plates or arms 68, 68, pivotted to the top of 63 (Figures 5 and 6). A portion
of the inside faces of these arms is curved and they are arranged when close to
encircle the tapered portion of the mandrel 6. A plate 70 (Figure 5) is secured
to the side of one of these arms 68 and overlaps the other arm. when closed
and forms a guide for the paper blank entering the mandrel. Springs 71 are
arranged to impinge against the backing plates or arms 68. The block 67 afore-
said is of more or less elliptical form so that when the spindle is turned said block
will open the arms.
Upon the mandrel is mounted a sleeve 72 which has, a recess formed by
flanges 73. This recess receives the bifurcated end of a bent arm 74 (Figures 5 and
6). This arm is received by and pivotted in a socket piece 75 which is loose upon
the shaft 1. A block 76 provided with radial arms 77 is fixed to the shaft 1
and which serves a double purpose namely to turn the spindle 6 as the
spokes 65, 66 come into contact with it and so open the arms 68 and cause the
bent arm 74 to turn outwardly upon its pivotted end as the said arm rides over the
inclined faces of the arms 77. The bent arm will thus move the sleeve forward on
its mandrel, the return of same being provided for by spring 78 connected
at one end to the said sleeve and at the other end to 13.
80 represents a receptacle which holds paraffine. This receptacle is supported
by plate 81 secured at the end of shaft 1. A pad 98 is set within the box being
supported by an arm 82 projected from sleeve 83 set upon rod 84. A stop collar 85
is set upon rod 84 beneath the sleeve and a small spiral spring 86 intervenes
between the said sleeve and collar, the sleeve being held by a nut 122. The rod
passes down through hole in guide frame at 87. A branch rod 88 projects from
said rod 84 and is arranged to ride upon cam 89 (Figure 4) which latter is set
upon the shaft 4; the end of the rod 88 is provided with suitable means to
enable it to ride upon the cam such as a bent plate 90. The box 80 is provided
with guide plates 91 for the arm 82 as it rises with the rod 84.
The shaft 1 is made hollow (Figure 6) and is provided at its end with a
connection piece 92 (Figure 1) for gas tubing or it may be connected with a gas
nipe. A Bunsen 93 (Figure 6) is connected with hollow shaft 1 and is provided
for the purpose of heating the paraffine in the receptacle 80.
In the drawings we have for the sake of clearness shown one mandrel only, but
the machine illustrated is adapted to carry and operate four--the feeding
mechanism also would be in duplicate to feed a mandrel in position on disc
opposite to that shown (Figures 1 and 2).
The modus operandi of the invention is as follows-(the operation of one
mandrel only being described the others being analogous and synchronous in
action). Assume the machine to be in position shown on Figures 1, 2 and 3.
When in this position the box 30 will have descended and its gummed roller 31.
will have picked up a paper blank and on the further rotary motion of the shaft 4
in the direction indicated by arrow (Figure 2), the box 30 will be moved

page_text: forward as the cam 27 on shaft 4 forces out the pin 26 on the
frame 24. The paper blank will thus be fed to the mandrel 6,
the mandrel being in the meantime retained in its position by the
pin 53 on the plate 50 entering hole in 54 and which prevents the discs from
furning, the gear wheel meanwhile rotating out of gear with the disc 2,
the bevelled edge of rim 46 will come in contact with roller 49 so depressing
it and withdrawing the pin 53 from its hole when the disc will be free to rotate,
and the toothed portion of the wheel 3 will again meet the teeth of disc 2
and thus cause it to rotate--at the same time the pinion 7 on the mandrel
will meet the teeth of the fixed segmental frame 11 so causing the mandrel
to rotate and to wind the paper blank upon it into the desired form. The paper.
which has had its edge gummed by the roller will be retained in the tubular
tapered mouth piece form. On the further rotation of the disc 2 an arm 66
(Figure 6) on the spindle 64 will meet the curved surface of arm 77 so causing
the spindle 64 to turn and the head 67 to open the arms 68. The mandrel
will have now reached a position directly above the pad 98 (Figure 5) and the
next block 5+ reaching the pin 53 will now hold the disc with the mandrel in
this position. The wheel 3 will now be again out of gear with the disc 2 and
on further rotation of the shaft 4 the cam 56 will operate to raise the bar 55 so
as to elevate the rod 57 and cause the rack 59 to turn the segment 61 and.
bring it into gear with the small pinion 7 so as to turn the mandrel, but while this
is taking place the cam 89 (Figure 4) will have been turned so as to raise
the rod 84 (Figure 3) to cause the paraffine pad to press upon the mandrel--the
paper tube will thus have its end coated with paraffine. After this operation the
wheel 3 will again gear with the disc 2 so as to further turn it and so cause the
spindle 64 (Figure 6) to be further turned as its arm 66 moves over 77 and the
head 67 will turn so as to allow the arms 68 to move towards each other; at the
same time the bent arm 74 will ride over an inclined face of one of the arms of
block 76 so as to move the sleeve 72 outwardly and throw off the mouth piece now
finished, and the spring 78 will cause the sleeve to be returned to its normal
position. The arms 68 will close upon the mandrel which will now have
reached a position to again receive a paper blank from the duplicate feeding
mechanism (not shown) and the operation of making a mouth-piece will be.
repeated.
We may alternatively construct the gum box as shown Figures 7 and 8 it being
in this arrangement supported by arms 105 secured upon a vertical spindle 106
having bearing in standard 107. The standard has a slot 108 in it and a pin 109.
upon the spindle 106, projects through the said slot and is arranged to be
operated by cam 110 upon shaft 111, the said shaft being actuated from any
moving part of the machinery convenient for the purpose. The pin 109 is divided
and the divided ends 118, 119 are arranged to travel upon the cam which has
two ways formed one by the main plate 110, the other by plate 120 secured thereto.
In operation assuming the cam to be in the position shown (Figures 7 and 9)
on rotation of the shaft 111 in direction indicated by arrow (Figure 7)
the cam will be disengaged from 118. A spring set in any convenient position for
the purpose will cause the spindle to turn and pin 109 to move in 113 so as
to descend in slot 108, and box 112 will fall to pick up a paper blank.
end 119 of the pin 109 will now ride upon the cam and along the plate 120 during
which time it will again turn the pin 109 into slot 113, the roller meantime feeding
the mandrel with the paper it has previously picked up. The end 118 will now
ride upon 110 and pin and spindle will again fall and the roller 31 will pick up a
fresh sheet.
The
The slot 108 is extended upwardly and has cross slot 114, the object of this
extension being that an operator may elevate the box and by turning the spindle
cause the pin 109 to be held in 114 during which time he may refill the box 17
with paper blanks 102.
