An Improved Machine for Forming Packets for Containing
Cigarettes, Cigars, Tobacco, and the like.
I, EDWARD THOMAS POLLARD, of 10 and 11 Stonecutter Street, Farringdon
Street, London, Engineer, 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 relates to an improved machine for the manufacture of packets
for containing cigarettes, cigars, tobacco and the like, and has for its object the
construction of a machine which shall be capable of forming the packets or cases
for the before mentioned purposes, from paper blanks more expeditiously than has
hitherto been effected.
The machine consists essentially of a table or base plate supported upon suitable
legs or standards and having bearings attached to the underside thereof, which
support a shaft by means of which motion is imparted to the various moving parts
of the machine. Upon the table are mounted two fixed circular horizontal plates,
between which revolve a number of arms, upon which are formed the packets or
cases before mentioned.
The paper blanks are held by a container, from which they are taken by means
of a fork and are so arranged that a predetermined quantity of gum or paste is
placed upon the side and end of same before they are delivered to the folding
mechanism. An apparatus for gumming the papers is provided.
In order that this invention may be the more readily understood, drawings are
supplied, in which
Fig. 1. is a plan of the improved machine.
Fig. 2. is a longitudinal section thereof, and
Fig. 3. is a transverse section.
Fig. 4. is a detailed view shewing the construction and method of operating the
gumming apparatus, the fork for feeding the paper, and the paper holder.
Fig. 5. is an end view of the paper holder.
Fig. 6. is a view shewing the method of operating a part of the folding
mechanism.
Fig. 7. is also a view of part of the folding mechanism.
Fig. 8. is a view shewing in detail the arrangement of the parts by means of
which the completed cases or packets are withdrawn from the metal pieces upon
which they are formed.
Fig. 9. is a side elevation of part of the above referred to arrangement shewing
the method of and means employed for operating the same.
Figs. 10 to 19 shew the various operations of folding the paper.
A. is the table or base plate of any suitable metal which may be mounted upon
legs or standard and carries by means of brackets B. B attached to the underside
a main driving shaft C, to which motion is imparted by means of a pulley C.
Upon the shaft C. is secured a toothed mitre wheel D. which engages with a
second wheel D₁ attached to a sleeve E. forming part of the disc F. which is
provided with an arm G. having a roller H. secured thereto. The disc F. is
mounted upon the end of a vertical spindle I. which passes through a suitable
bearing formed upon the table.
The roller H. upon the arm G. engages with a plate J. shaped as shewn by the

page_text: drawings and having four channels J J J J formed in the arms thereof, in
which the said roller engages during a portion of its revolution. The disc F. is
partly circular and is arranged so that the said circular portion shall engage with a
radial web formed upon the periphery of the plate J. during one portion of the
revolution of the disc F. whilst during the other it is free to revolve, a portion of
the dise being cut away to allow of this, as shewn by the dotted lines in Fig. 1. and
more clearly in Figs. 2 and 3. This arrangement prevents any accidental
movement of the plate J, the ends of the arms being circular to allow of
the free rotation of the plate when the roller upon the disc engages with the
channels J J J J.
The plate J. is mounted upon a vertical spindle K. which is carried by a bearing
formed upon the base plate A. and supports at its upper end a circular plate L.
A second plate L' is secured to the plate L. by means of screws or the like and
between these are clamped the pins M. which are part of the pieces M' upon which
are formed the cases. Mounted upon the base A. by means of studs N. and
nuts N¹ are two adjustable horizontal circular plates O.'0' each having a segment
removed as shewn in Figs. 1. 2. and 3. and it is between these plates that the
pieces M' revolve.
Mounted upon the shaft. C. is a cam P. Fig. 2. with which engages a roller P¹
upon fork P having attached to its free end a spindle P2 passing through a
guide P upon the base plate A. a spring encircles the spindle and is kept com-
pressed by the guide P. To the upper end of the spindle P is attached a
clamp P carrying a plate P which plate passes through a slot in the circular
plate O and turns or folds the paper carried by the metal pieces M'. A second
cam Q. is also mounted upon the shaft C. and operates, by means of a fork Q
roller Q and spindle Q a second plate which passes through a slot in the plate O
from the outside and folds the opposite side of the paper. "The fork Q' is similar
in form to the fork P but the roller in this instance, the direction of motion
being required to be reversed, is in contact with the lower edge of the cam shewn
in Fig. 2. a spring is attached to the fork to keep the roller always bearing upon
the cam.
n
At the end of the shaft C. is a mitre wheel R. gearing with a similar wheel R
upon a shaft R' carried in suitable bearings and having a second wheel R' mounted
thereon.
The last mentioned wheel is geared to a wheel R upon a spindle R passing
through the table A. and having mounted thereon a circular plate R upon the
underside of which a race is cut or otherwise formed to receive a roller R' carried
upon a rocking frame S. This frame consists of a plate carrying two arms S' S¹
and has lugs formed thereon which enable it to be pivotted to lugs formed on the
table or base A. Upon the upper face of the plate R' is a pin engaging with a
channel piece T. through which passes, and is secured a rod T¹. The rod T¹ also
slides through holes formed in the arms S S of the rocking frame Figs. 1. and 2.
To the end of the rod T is secured a fork T' having attached to the inner faces
thereof thin plates T with teeth cut upon the edges which project above the sides
of the fork to grip the paper against which they are brought to bear.
Opposite the fork T and mounted upon the table A. is placed the paper
container which consists of a square box U. open at the top and one end and having
two studs passing therethrough at the side which bear against a loose plate U¹ in
contact with the paper therein. At the end of the box is a boss through which
passes a rod U having ratchet teeth cut therein to allow of the same being
advanced as the paper is removed. To effect this a lever U provided with a
spring pawl U is mounted upon a spindle carried by standards U formed upon the
end of the box. A recess is cut in the boss in which is pivotted and moves a
second pawl U engaging with the teeth upon the rod to prevent any back
movement during the travel of the pawl U. A milled head is provided to with-
draw the rod when the box is to be refilled and a plate is attached to the opposite
end to bear against the papers as shewn Figs. 1, 4 and 5. The movement of the

page_text: lever U is effected by means of a lever V. which is attached to a pin V₁ passing
into the tubular rod V2 pivotted to the rocking frame S. as shewn Figs. 1 and 4.
Facing the container on the other side of the fork is the gum reservoir which
has a circular body W. having a cap at one end with two orifices W1 W2 shaped
as shewn Figs. 1 and 4. and by dotted lines in Fig. 5. Within the body is a
circular disc W which is moved by means of the screwed spindle passing through
a nut W held by the bracket supporting the whole upon the table A. A ratchet
wheel W forms part of the nut which is also free to rotate in the bearing formed
in the bracket. A lever We is provided having attached a pawl W' which
engages with the wheel. The end of the lever "We has formed therein a hole
through which passes a pin W attached to the lever W supported by the boss
forming part of or attached to the bracket carrying the gum reservoir. The
opposite end of the lever is pivotted to a slotted piece W secured to the rocking
frame Figs. 1 and 4.
Secured to the shaft C. is a cam a engaging with a roller upon a forked lever b,
the upper end of which is connected to a circular plate c which rotates upon a
spindle d carried by a bracket. Upon the face of this plate are two pins e
which are placed diametrically opposite one another and engage with eyes formed
upon the lower ends of the rods e e¹. The upper end of the rod e carries a piece f
at the end of which is a finger of triangular section which passes through &
hole in the plate O and the object of which is to turn over the end of the case.
The rod e passes beyond the plate O¹ and through a guide attached thereto and
has also a finger g of like section, which passes through a hole in the plate O, the
motion of the two fingers being in opposite directions and simultaneous. Upon
the plate e is an arm carrying a pin to which is attached one end of a spring of
which serves to keep the roller on the cam h is a cam mounted upon the shaft C.
and operating by means of a roller a forked rod h. This rod has formed at its
outer end a small toothed rack 2 which engages with a wheel mounted upon a
spindle M. The spindle is carried by the bracket i and has attached to it at its
upper extremity a boss to which is secured the radial folding piece i'.
A collar having an arm thereon is attached to the spindle and has a spring i to
keep the roller upon the rod A' always in contact with the cam h. To keep the
rod 4 in position a portion of the bracket i is so formed as to support the rod at
the end as shewn Fig. 7.
Cast or otherwise formed upon the plate O. is a projecting piece to which is
pivotted an arm carrying a roller over which passes an endless band of
any suitable material. The baud also passes over rollers carried upon the
plates O. O and so situated as to allow of the pieces carrying the packets to come
into contact with the said band after leaving the radial folding piece i. To allow
of the necessary movement and at the same time to keep the band always stretched
a spring k is provided, oue end being attached to the arm j and the other to a pin
upon the base plate or table A.
Secured to the spindle 1. and underneath the base plate A is a cam upon
which bears a roller attached to a forked lever one end being pivotted to a
second lever, a boss being formed upon the last mentioned lever on the under-.
side, and extending downwards through the table A. for the purpose. One end
of the lever is carried upon a sleeve formed at the upper end of a bearing m
secured to the table, and the other carries two pieces of metal shaped as
shewn Figs. 1 and 8 and pivotted thereto. The pieces have at their smaller
ends upon their undersides two studs n n against which bear the ends of a spring n'.
To limit the action of the said spring two pius n n are placed as shewn Figs. 1
and 8. at the side of the pieces so that when the lever to which they are
pivotted is moved towards the plates O. O' the ends open and the rollers engage
with the case and draw it off.
As will be seen from the drawings two spindles are secured to the pieces
having sleeves thereon which carry the rollers the object of the said
rollers being to draw the finished packet or case from off the pieces upon which

page_text: they are formed and at the same time to give the said packets a perfectly square
section at their open ends. To impart the necessary motion to the rollers the two
outer ones have formed upon them grooves for a belt Figs. 1 and 2. Carried by
the bearing m is a spindle m' which has secured at both ends a pulley m² m² over
which pass cords m m one of the cords passing over the grooves upon the outer
rollers on the sleeves whilst the other receives its motion from a pulley upon a
sleeve forming part of the mitre wheel D. as shewn at Fig. 3.
The action of the machine is as follows:-
Motion being imparted to the shaft C. causes the roller upon the plate c to
engage with one of the channels in the plate J. thereby rotating the discs L. L'.
At the same time the bevel wheels actuate the rocking frame S. and bring the
fork T to bear upon the paper and carry same forward. The paper is next
caught by one of the pieces M' and carried forward turning up the sides as shewn
Fig. 10. When the paper is opposite the plate P the roller is free of the channel
and the motion of the paper ceases. The cam P. then causes the above mentioned
plate to advance and fold over the side of the paper, the gummed side being
uppermost Figs. 11 and 12. When the plate has completed its action, the cam Q.
then advances the opposite plate, thereby folding the opposite side of the paper.
The plates being withdrawn the paper is advanced by means of the roller again
entering one of the channels and moved until it is opposite the fingers f¹ and g
Fig. 14. which fingers being caused to advance by means of the rod b actuated by
a suitable cam, imparting motion to the plate c and rods connected thereto, turn in
the ends of the partly formed packet, as shewn Figs. 15 and 16. the sides at the
end being afterwards turned down by the radial folding piece 2 which caused
to move by means of a cam in contact with the roller upon the rod the teeth
formed thereon actuating the wheel 23 attached to the spindle carrying the said
radial piece, Fig. 17. Upon the continued movement of the piece M¹ the end
of the packet is brought into contact with the endless band j³ which effectually seals
the end as shewn Fig. 18. When the completed packet is over the rollers 1.
the cam causes the lever 12 to be raised and at the same time the rollers opening
under the action of the spring n³ seize the packet and withdraw it from off the
piece M¹ forming the sides and giving it a perfectly square mouth, Fig. 19. The
operation of the various parts being repeated every one fourth of a revolution of
the plate J.
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 1
claim is :-
1. In packet making machines the use of adjustable circular plates 0. 0¹ in
conjunction with the folding fingers and mechanism for folding the paper,
substantially as described.
2. The combination of parts forming the paper retainer or holder with the gum
or paste reservoir, with feeding fork, substantially as described.
3. The mechanism for removing the finished packets from the machine,
substantially as described.
4. The improved machine for forming packets for cigarettes, cigars, tobacco,
or other like purposes, substantially as described and set forth in the accompanying
specification and drawings.
