Improvements in Oigarette maonines.
HERMAN MANDELBAUM of No. 202, East 46th Street in the City and County
of New York, State of New York, United States of America, Manufacturer, 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 improvements in cigarette machines, in which provision
is made for automatically separating a "filler "from a snpply, rolling it within the
wrapper, and trimming the rolled cigarette.
The object is to simplify the mechanism for accomplishing the above-named
results, and to so arrange the operative parts, that the machine will be compact,
and capable of being attonded without requiring special skill of the operator.
In the accompanying drawings:-
Fig. 1 is a view of the machine in side clevation;
Fig. 2 is a view in front elevation;
Fig. 3 is a view in vertical section from front to rear, along the plane of the
line 3-3 of Fig. 2; and
Fig. 4 is a partial view, in side elevation, at the opposite side from that shewn
in Fig. 1, and reversed as to the positions of front and rear.
The framework of the machine consists of a pedestal A supported upon legs a,
and surmounted by a rearward extension A' for the support of the feed mechanism,
and by a top plato A' for supporting the rolling table, and supporting a hanger ai
in which the drums or rollers for the finishing belt are mounted.
The main shaft from which motion is transmitted to the several parts of the
machine, is denoted by B, and is provided with fast and loose pulleys 6 61 of any
well-known or approved form, for the reception of a driving belt leading to a
source or power, not shown. The shaft B is provided with a cam C for actuating
the feed; a cam C' for effecting the primary rolling of the oigarette; a cam C
for effecting the trimming of the cigarette; a cam C for operating the knife
which severs the filler from the supply, and a wheel C for operating the secondary
or finishing rolling.
The rolling table on which the primary rolling of the cigarette takes place, is
denoted by D, and over it extends the rolling apron d, fixed at one end to the
front of the table D, and extending theuce over the table, and down into a
depression d' at the rear of the table, thenre upwardly to a rod d, where its
opposite end is fixed. The rolling apron d is made readily detachable from the
machine, for purposes of renewal or cleaning, by having its rear end provided
with a loop d', through which the removable rod d passes, ad which latter has
'its ends engaged with the sides of the supporting 'frame A'. The opposite eud
of the apron d is held last between the under side of the table Daud a
clamping block d', which may be adjusted to and from the table D by means of a
set screw d
.
Above the depression a, into which the apron uaturally falls, to the position
shown in Fig. 3, to receive the filler from the supply, there is located a permanent
frout plate E, having sides e e, and a swinging bottom, sitles, and top,
respectively, which, together with the front plate E and its sides, form a
receptacle of a blunt V-shape at its bottom -in cross section for the charge of
material which is to form the filler. The bottom of this receptacle is located

page_text: intermediate between the plane on which the tobacco, which is to form the filler,
is fed, and the rolling apron, and serves the purposes of levelling the charge which
is to form the filler, and permitting it, when the bottom e', together with the
sides e, are swung away towards the front into the position shewn in dotted lines,
to fall in a compact, evenly distributed mass into the open loop in the apron.
A spring e, fixed at one end to the front of the plate E, and at its opposite end
to an arm projecting forwardly from the swinging top e, serves to hold the
bottom and sides in their rearward position, to complete the receptacle for the
filling charge of tobacco, and those parts are positively swung forwardly, to drop
the charge into the loop in the apron, by means of trip lever F, fixed to a
spring actuated rock shaft f, one arm of said lever being in position to engage n
rearwardly-extending arm e' on the swinging top of the receptacle, to open the
receptacle, and the other arm of which is in position to engage an operating nuзe g
fixed to reciprocate with the knife G, which severs the charge of tobacco from the
supply.
The knife G is mounted to reciprocate vertically in the front portion of the
frame A', and is operated by the free end of a lever g pivotted to the frame A¹
at 9, and connected by a rod g with the cam C on the shaft B. The cam C³, by
its engagement with the connecting rod g, serves to lift the rod, and hence the
lever g', and hence the knife, until the laterally extending stud or roller g' on the
rod 9 reaches the ledge on the cam, when the said rod, and the knife G connected
therewith, are caused to suddenly drop by means of their own weight, and the
tension of the actuating spring g connected with the rod y, and with the fixed
support upon the pedestal A.
fixed on its shaft (see

The vibrating arm
The supply of material to form the fillers is fed to the knife G by means of an
endless apron H carried by drums or rollers h, mounted in the frame A'. The
drum or roller is operated by means of a ratchet wheel
Fig. 4), which ratchet wheel is operated upon by a pawl
arm mounted concentric with the axis of the roller h.
bas a slot and pin conuection of any well-known or approved form, with a con-
necting rod h, which leads to the cam C on the main shaft B, by which the arm h
is vibrated at suitable intervals, to advance the apron El, carrying the supply
forward to be severed by the knife G. The vibrating arm is given a throw to
move the pawl the full distance which will be required for the greatest charge or
filler that may be desired, and its effective action in turning the ratchet wheel /³ is
limited, at pleasure, to make the feed, and heuce the charge less than the greatest
amount, by means of a circular curved guard h, having a screw ho engaged
therewith, and with the supporting frame A', in such a manner that the guard h
may be slipped in one direction or another around the periphery of the ratchet
wheel h³, to protect more or less of the ratchet teeth from the action of the pawl h,
. as may be desired.
The drun or roller h has fixed to rotate therewith a gear wheel ho, which inter-
meshes with a gear wheel A', fixed to rotate with the compression roller 4*, which
serves to compress the supply of tobacco into a flat, compact sheet, before it
reaches the path of the knife G. The apron H is kept at a euitable tension by
nieana of a tightening roller I carried in the free end of an arm i of an angle levor
pivotted to the frame A' at , the opposite arm of said lever having engaged
therewith a set screw i, bearing at its free end against the top A' of the supporting
frame, and so that, by turning the srrew in or out, the roller I may be forced
towards or away from the apron H, to tighten or loosen it.
The rolling aprond is operated to roll the cigarette, after the filler has been
dropped therein, and the wrapper laid thereon, by the following mechanism :-
A vibrating arm K is pivotally secured at its lower end, at k, to the pedestal A,
and extends upwardly to a point to the rear of the rear portion of the apron d,
where it is provided with a rocking compressor L, pivotied thereto. The vibrating
arm K is provided, intermediate of its pivotal point and the compressor, with a
laterally extending stud carrying an anti-friction roller ', which is located in

page_text: position to bear against the cam C, which, as the shaft B is revolved, forces the
arm K forwardly, carrying the presser L along over the rolling table D. The arm
is retracted by means of a spring .
The compressor L bears normally against the apron, as shewn in Fig. 3, near
the pintle on which it rotates, but, as it is advanced by the arm K, it is rocked
into an upright position, shown in dotted lines in Fig. 3 by the engagement of an
arm (see Fig. 1), extending at an angle to the compressor L, and preferably
carrying on its end an antifriction roller 1, which engages the track at the sido
of the table D, so that the slack of the rolling apron is taken up, and, when the
arm K finally reaches the position shewn in dotted lines in Fig. 3, the pocket in
the rolling apron, which originally contained the filler in which the wrapper was
finally rolled around the filler, will be straightened out, and the cigarette, having
nndergone its primary rolling, to place the wrapper around the filler, will be ejected
from the apron into a downwardly-slanting passage-way m between a slanting fixed
plate M and the face of the secondary or finishing rolling apron m'. The com-
pressor L is retracted by means of a spring 4, when its arm 7 is disengaged from
the track, as the arm K is returned.
The secondary or finishing rolling apron is mounted upon drums or rollers m³ m³,
the latter having fixed to rotate therewith a sprocket wheel m', which is connected
by a chain m with the wheel C on the shaft B. The apron m' is tightened and
loosened, as may be desired, by means of a tightener roller m mounted in sliding
boxes m carried by the hanger a', and adjusted by means of screws m³.
As the cigarette passes from between the plate M and the apron m', it is
received, at or near its ends, upon the curved edges n of stationary blades N, and
while so supported, its ends are trimmed squarely off by means of rocking blades
pivotted to the stationary blades N, so that their cutting edges shall conct, as the
blades are rocked, with the edges n of the stationary blades. The rocking blades O
are actuated to effect their cut by means of a spring P connected at one end with
the shank of the blade O, and at the opposite end to a suitable support upon the
pedestal A. The blade O is retracted, and held in its position away from the
cutting edge of the stationary blade, as shewn in Fig. 3, by means of a rod o,
connected at one end to the shauk of the blade, and at the opposite end provided
with a laterally projecting stud o', preferably provided with an antifriction roller
which bears against the sunil cam C. As the stud o¹ passes the outer edge of the
ledge on the snail cam C2, the spring P is permitted to suddenly act, and throw
the cutting blade O forward, to cut while the stud o' is promptly brought into
engagement with the cam, which again gradually forces the blade O back out of
the way of the next succeeding cigarette.
As the ends of the cigarette are trimmed by the rocking blades O, the completed
cigarette falls from the kuives into a suitable receptacle, to be removed at
pleasure.
For the purpose of keeping the edges of the entting blades O and N free from
gum, and in condition to do their work perfectly, I provide for wiping off any
foreign substance which may accumulato upon them as follows:-
A brush Q is fixed to a suitable support y extending forwardly from the arin K,
and so arranged that as the arin K advances to effect the primary rolling operation,
the brush Qwill be forced between the cutting blades located at the opposite ends
of the cigarette and rubbing against them with sufficient friction to thoroughly
clean them at each advance movement of the arm K.
The operation of the machine is as follows:-
The parts being in the position shewn in full lines in Figs. 1 and 2; as the
cam C is further rotated to carry the rod 4 to the limit of its rearward movement,
it will advance the supply of tobacco on the feed apron H, so that the charge will
project in frout of the path of the cutting edge of the knife G. At this
moment, the cam C which operates the kuife G, has reached the point where
the rod is permitted to drop from the periphery towards the centre of the
cam, and the blade G will fall, severing a sufficient quantity of tobacco from

page_text: the supply to form one filler. As the blade G descends, the nose 9 on its face
will pass idly by the lever F.
:
The return movement of the blade G will rock the lever F, by the engagement
of the nose g therewith, in a direction to swing the sides and bottom of the
temporary receptacle for the filler, towards the front, thereby permitting the
charge within the temporary receptacle to fall into the pocket formed in the rolling
apron within the depression d' of the table. As soon as the filler is adjusted on
the rolling apron, the arm K, carrying the compressor L is advanced by the cam C',
thereby closing the apron d around the filler, and, the wrapper having been laid
upon the apron d before the advance of the arm K, the said wrapper will be tightly
rolled about about the filler, as the latter is carried along within the loop in the
apron over the stationary table D. The apron d, as soon as the rolling action
begins, is tightened by the rocking of the compressor L into an upright position,
and is so held until the arm K reaches the limit of its forward stroke, shown in
dotted lines in Fig. 3, at which moment the cigarette will be ejected from the loop
in the apron d into the passage way between the secondary rolling apron m' and
the plate M. After passing between the said apron and plate, and receiving its
finishing rolling, it will rest upon the stationary blades N. As the arm K
advanced, it carried the brush forwardly into engagement with the trimming
blades, and as it began its rearward movement while the cigarette was being rolled
between the apron m and the plate M, the brush was carried back from its wiping
position, and the movable trimming blades O were promptly operated to trim the
cigarette by the action of the cam C, which, just after the cigaretto is dropped
onto the stationary blades, reaches a position which permits the rod o to drop
from the periphery towards the centre of the cam, under tension of the
spring P.
The timing of the parts is such that, while the primary rolling action is taking
place on the table D, a previously-rolled cigarette is being trimmed by the
blades N, O, and the supply is being fed forward, and a charge to form the filler
severed, and deposited in the temporary receptacle. The temporary receptacle is
opened, and the filler deposited in the pocket in the apron d, just as the arm K
reaches the limit of its rearward movement, and the previously gummed wrapper
may be placed on the apron d on the table D at any moment after the arm K has
receded, to lay the apron d on the table, and before it is advanced, so as to bring
the closed loop in the apron into engagement with it.
