A New or Improved Machine for Opening and Cutting Oigarette-
paper Tubes.
I, HUGH DONALD FITZPATRICK of 70 Wellington Street, Glasgow, Registered
Patent Agent, do hereby declare the nature of this invention and in what manner
the samo is to be performed, to be particularly described and ascertained in and by
the following statement.-
This invention has reference to a machine operated by hand or by power, which
is designed to open a paper tube of auy suitable length previously wound upon a
bobbin and to cut off portions in order to make cigarette tubes of square or other
desired shape.
And in order that my sand invention may be properly understood I have hereunto
appended two explanatory sheets of drawings, whereon,
Fig. 1 is an elevation of the left hand side of the machine.
Fig. 1 is a view of a portion of the machine.
Fig. 2 18 a plan of the machine
Fig. 3 is an elevation looking towards the scissor mechanism.
Fig. 4 shows side and front views of the tube-opening tool
Figs. 5 and 6 are detail views.
Referring to the drawings.-
The machine is mounted on a column or pillar A upon which are fixed the
various parts for causing the bobbin, whereon the paper tube is wound, to unwind,
and for feeding forward the said tube, opening it, cutting it off into equal lengths
and then delivering the separate pieces into a suitable receptacle.
In
Upon one side and at the foot of the pillar A is cast an arm b through which
passes a rod B, securely held in place by a pincing screw, and which supports at
one end a fork C carrying on suitable bearings, the spindle of the bobbin E. Upon
the latter, which is provided with two flanges, paper tubing is wound by means of
suitable mechanisın A brake F, consisting of a grooved pulley upon which a belt,
controlled by a spring F, bears frictionally, regulates the uncoiling motion.
front of the pillar A and above the same is fixed a strong steel plate D carrying
the other parts of the machine. Two arms W fixed upon the plate D carry, by
means of bearings, the shaft G upon which are mounted the fast and loose
pulleys M, L, the thrue cams I, J, K and the fly wheel H. The cam J, keyed on
the shaft G, actuates the guide II'.
The cam K keyed on the shaft G imparts a motion to the feed rollers.
The cam I keyed on the shaft G actuates the BOISSOгB.
Two horizontal arms N N carry the feed rollers O, P, and the gears actuated
thereby as well as the soissors and the shoot or delivery tube G'. The roller P,
which is keyed on the shaft Q, actuates by friction the roller . There is also
keyed upon the shaft Q, the cam R having two teeth and the biake S. Moreover
the same shaft Q carries between the cam R and the roller P, a disc T provided
with a pawl V and a toothed pinion U forming an integral part of this disc which
is adjustable on its shaft, and a spring v for causing the pawl V to bear constantly
upon the periphery of the cam R. The pinion U is actuated by means of a toothed
wheel X set in motion from the grooved cam K by means of the rocking lever Z

page_text: (pivotted at) having the roller at its upper end which works in the groove of
the cam, and the connecting rod Y. The horizontal scissors or shoars Ä' which
are jointed together at a, have their blades opened by the action of the cam B'and
closed by the action of the spiral spring C. The cam B' 18 keyed on a vertical
axis D to which a reciprocating motion is imparted from the grooved cam | by
means of the crank D', connecting rod E' and lever F wliose roller a works in the
cam groove. When the scissors A' have acted, the length of tubo cut off is fed
forward, in the manner shown in dotted lines at Fig. 1A, by a concave piece II',
acting as a guide, into the discharge tube G'. This guide H' is actuated by the
cam in its forward motion, as indicated in dotted lines Fig 1A, and by a counter-
weight K', suspended by the cord K' led over the pulley K³ and connected to the
lever J, in its backward motion. The small oscillating lever J', acted upon by the
counter weight K' on the one hand and by the cam Jon the other hand actuates
the rod which is attached to the guide II' and supported by the piece M.
The machine is completed by an independent piece, viz., the opening rod or tool N'
which is of special form (as shown in Fig. 4) having the shape of a solid cylinder
flattened at its two extremities, the lower extremity 3 being wedge shaped so as to
readily enter the paper tube and the upper end 4 being gradually tapered the two
flattened and tapered surfaces 3, 4 are at right angles to each other
When the machine is working, the opening tool N₁ which is placed in the paper
tube, is held in a vertical position by the rollers O₁, which act likewise as guides toi
the tube, and by the forks P' Q' which are perpendicular the one to the other
Fig. 5 is a full size front view of the cam K for actuating the feeding rollers, and
Fig. 6 is a similar view of the cam I for actuating the scissors. In both these
figures the rollers and are shown in the positions which they both simultaneously
occupy when the scissors are opened
The paper tube, fed by the bobbin E, and guided by the parts O, P, Q and
the opening tool N₁ placed within the same, passes up between the teed rollers (), P.
The modus operandi is as follows –
If the fly wheel H, is tuned in the direction shown in Fig 1, the cam K will
pull, by means of its groove, the roller k inwards towards the coutre of the cam
.e. from the position c to a Fig. 5. This movement of the roller & causes the rocking
lever Z, which is pivotted at 2, to move, at its lower end, towards the left and
thereby pull the connecting rod Y, which actuates the gearing X U, in the same
dnection. This movement causes the pinion U (which is formed integrally with
the disc T) and the pawl V to impart a motion to the disc and also to the shaft Q
and feed ioller P by means of the double toothed cam R. As a result of this
motion the paper tube is fed upwards, above the scissors A1, a distance corresponding
to the length of a cigarette; it is at this moment that the scissors are operated so
as to cut off a length of tube and let it fall into the guide II' as hereinafter more
fully explained.
The travel of the roller from to d in the groove of the cain K exactly
corresponds to the distance the cam R is mored forward by the panl V at each
movement of said pawl.
Oue length of tube having been fed upwards, the roller & continuing to travel
round the groove of the cam K from d to r causes the lover Z to perform a backward
recipiocation or a movement towards the night (Fig. 1). This movement reverses
the notion of the connecting rod Y, gearing X U and disc T, but, as the pinion
and disc are loose on the shalt Q, 1 does not affect the shaft or the feed roller P.
This reti oginde movement continues until the pawl V falls before the second tooth
of the cam R. It is during thus momentary cessation or stoppage of the feed that
the tube is cut off
The scissors A are opened by the action of the cam B which is formed in one
piece with the rod D'. This rod receives an oscillatory motion from a connecting
rod actuated by the lever F1 with the roller at its upper end. During the
greater part of each rotation of the cam 1 (Fig. 6) the follor and pivotted
lever F' remain motionless, that is to say, during the period taken by the roller i to

page_text: travel from e to f (Fig. 6) no motion is imparted to the lever F. On the other
hand, when the roller is travelling from to g the lever is caused to oscillate
slightly, and, by means of the connecting rod E', ciank E' and rod D', to turn
the cam B a quarter of a revolution which is sufficient to close the scissors A¹
against the action of spring C. As the cam I continues to rotate it causes the
cam B' to return to its original position and thereby enable the scissors to be opened
again by the action of the spring C'.
The piece of tube 5 after being severed is thrown into the open mouth G³ of the
shoot or discharge pipe G', (see dotted lines Fig. 1^) by the guide H' fixed to the
bolt L' actuated by the reciprocating lever J', fulcrumed at J, to which an impulso
19 imparted, after each severance by the cam J keyed on the shaft G, which, at
the proper times, acts on the roller I at the upper end of lever J. The bolt is
brought back again, after each forward movement, by means of the counter-
weight K attached to it by the cord K².
The machine can either be actuated by hand with the aid of the fly wheel H or
by power by means of the pulleys L M.
I may produce a tube of square or of any other suitable section by merely
altering the shape of the opening tool. I can also cut the tubes in various lengths
and other wise modify the parts of the machine without departing from the nature
of the invention.
Having now particularly described and ascertamed the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
consider novel and desire to claim is.
1. In a machine for opening and cutting cigarette-paper-tubes, the combination
of a bobbin on which the tubing is rolled with an opening tool acting by gravity
and feed rollers for feeding the tube to the scissors, substantially as hereinbefore
set forth.
2. The combination of the two cams K, I, one of which actuates the feeding
mechanism, whilst the other actuates the cutting mechanism, substantially as
herein before described and shown on the drawings annexed.
3 The combination with the machine as hereinbetoic described, of the mechanism
for delivering the cut tubes into the shoot G, substantially as hereinbefore
described and shown on the drawings annexed.
4 The general arrangement and combination of parts of the machine,
substantially as hereinbefore described and shown on the diawings annexed.
Dated this 24th day of December 1894.
