SCRAP TOBACCO FEED‘
John F. Halstead, Brooklyn, N. Y., assignor to
International Cigar Machinery Company, a
corporation of New Jersey
Application June 5, 1935, Serial No. 24,992 i
43 Claims.
This invention relates to improvements in
scrap bunch cigar machines, more particularly
to the tobacco feed thereof. The main object of
the invention is to provide automatic regulation
.5 of the quantity of tobacco fed from the hopper
to the measuring chamber at each ‘cycle of the
machine, this quantity in the present tobacco
feed being controlled by the amount of tobacco
remaining in the measuring chamber on com
pletion of the preceding cycle. Other objects of
this invention are to portion the successive quan
titles of tobacco without cutting the scraps, to
simplify the mechanism for actuating the charge
compressing plunger, and to provide for making
15 tapered bunch charges. With these and other
objects not speci?cally mentioned in view, the

by a cam which opens the same at the proper w
time and closes when the pocket is ?lled, without
cutting the scraps. The motion imparted to the
shutter from its cam is transmitted through
mechanism including ‘a yieldable arm connected
to the shutter through a lever so that, in case of
any obstruction to closing of the shutter, the lat
ter will be arrested through the yielding of the
arm.
The said yieldable arm carries an adjust
able screw,'bearing against the lever connected 10
to the shutter, thus providing positive motion for
openingthe shutter.‘

No. 1,915,525, granted June 27, 1933, on the ap
plication of F. C. Gladeck, et al., the tobacco feed
is so arranged that its operation is controlled by
, the quantity of tobacco left in the measuring
25 chamber, so that in the next cycle themeasuring
chamber receives either a full quantity or noth
ing at all. This action causes the tobacco con~
tents in the measuring chamber to vary abruptly
between wide limits, thereby causing variations
in tobacco density in different bunches due to the
varying length of the column of tobacco to be
compacted. In order to assure greater uniform
ity of the bunches, the tobacco feed in the pres
ent machine has a variable feed pocket which

able pocket may consist of stationary end and
40 side walls and of a swingable bottom constitut
ing a gate and ?tting between the sidewalls
and terminating at the end wall, the curvature
of which is concentric with the axis of ‘the gate.
In each cycle of the machine, ‘this gate is swung
upwardly by a cam from an adjustable initial
position of maximum pocket depth and is ar
rested by a ratchet segment set during the pre
ceding cycle by ‘the movement of the compres
sion plunger which, in turn, is controlled by the

vention. The shank of the plunger, as hereto
fore, carries a ?nger engageable with a swingable
arm which in the present machine transmits
the forward motion of the plunger beyond their 45
point of engagement to the aforementioned
ratchet segment to set the latter into position
for arresting the upward motion of the bottom
of the pocket. The greater the mass of tobacco
'in the measuring chamber, the smaller is the ,_
extent of the forward motion of ‘the plunger re
quired to ?ll the charge-measuring pocket, which
forms 'a continuation of the measuring chamber,
with tobacco; hence the ratchet segment will
advance less toward the said bottom, whereby
2

the latter will rise higher and make the pocket
smaller, in inverse relation to the quantity of
tobacco in the measuring chamber.
In the accompanying drawings which form a
part of this speci?cation and in which like char
acters of reference indicate the same or like
parts:

to receive the quantities of tobacco dumped from
said pocket, a device for compressing the mass of
tobacco thus accumulated in said measuring
chamber, and means ,controlledrby said device
25 for regulating the capacity of said pocket in
versely to the amount of tobacco in said meas
uring chamber. In the best constructions con
templated the feed pocket is, provided.with a
swingable gate or bottom, and the regulating
30 means is connected to said bottom to raise the
same within the pocket, and the compressing
device controls the extent to which, the bottom
is raised by the regulating means, whereby the
capacity of the pocket is regulated. Further
35 more, in the best constructions, the regulating
means acts tovlraise the bottom of the pocket
after the same is ?lled with tobacco and thereby

The shutter I0 is guided by_rollers H sup,

During its downstroke the rack 29 drives the
pinion 21 and thus turns the gear 26, the arm 33
being turned with the latter by the spring‘ 34
until pin 31 engages with the ?at face 320 on one
end of the ratchet segment 32,‘the latter being
held‘stationary by the spring-pawl 40. The gate
9 is‘ ‘thus set into position to provide the proper
depth‘ of the pocket for the quantity of tobacco
required, the spring 34 stretching while the gear
16 26 completes the remainder of its swing. Upon
the return ‘motion of gear 26 corresponding to
‘the upward stroke of rack 29, the block 4| raises
the pawl 40, thus allowing segment 32 to be turned
back to its initial position by the weight of the
connecting rod 42, arm 43 and stop-arm 4E.
The cam which actuates rack 29 is so timed
that the upward stroke‘ of the latter will occur
after the pocket has been filled and the shutter
M, has ‘closed, to ‘swing the gate 9 down to its
lowermost position 9' (Fig. .1), whereby the con—
tents of the pocket will be discharged through
chute ‘Ill and ‘I I‘ in‘to a funnel T2 surrounding the
sides and free end of the trapdoor 6! which has
swung open at that time to form the fourth wall
25 of the funnel. The rack 29 is thereupon actuated
by the said cam to raise the gate 9 to position 3”
with its free end at the top of the pocket and
‘ ?nally return it to initial position 8, this upward
motion occurring while the shutter I0 is opening
and‘serving the purpose of clearing the pocket
walls‘ of any adhering tobacco, particularly at the
portion opposing the lip of the shutter.
‘ To ‘part the tobacco ?lling the pocket from that
in the hopper, the shutter ID is provided at its
forward end with a curved resilient blade 13
overhanging the same and also serving to sweep
out scraps or lumps of tobacco lying between the
lip of the shutter and the opposed wall of the hop‘
per outlet, which would otherwise obstruct the
40
closing of the shutter.
‘
While the gate swings from position 9 to posi~
tion 9", the shutter l0 opens and remains ‘open
while thegate swings back to position 9 and until
it is raised to its ?nal position as determined by
the‘ setting of ratchet 32 as hereinafter described.
Upon the return of the gate to position 9 on its
downswing, the action of the agitators (not
shown) , in the hopper assures‘ ?lling of the pocket
sothat the subsequentupward motion of the gate
returns to the hopper the‘ surplus quantity of
tobacco in the pocket, thus eliminating air pock
' ‘As the plunger‘ 52 is moved forward with the
block 66 by the pressure of the spring 63 to com
press the mass of tobacco T in the measuring
chamber 60, the inlet of which is closed at this
time by‘ the trap-door 6|, the screw 49 engages
with the lever 48,‘ thereby swinging the arm 43
and causing the rod 42 to move upward and turn 10
the ratchet segment 32 in the forward direction,
indicated by the‘ arrow in Fig; 1, to its initial posi
tion. If the amount of tobacco Tin the measur
ing chamber 63 is so great that the charge-meas
uring pocket 62, which forms a continuation of
the latter, is ?lled with tobacco compressed to
the‘ required density before the screw 49 engages
the arm 48, the arm 43 of course will not be turned
and the ratchet 32 will remain in its initial posi
tion shown in full lines in Fig. l and permit the 20
gate 9 to be swung up to the position of minimum
pocket depth. vOn the other hand, if the mass
of tobacco in the chamber 60 is so small that the
plunger 52 must go to the limit of its‘ stroke to
?ll the charge~measuring pocket, then the arm
48 is swung‘ to position 48' and the ratchet 32
is turned to its extreme position shown in dotted
lines, in which position its forward end 32a en
gages the pin 31 of arm 33 and thus prevents
movement of the gate 9 from the‘ position of max
imum pocket depth. For any amount of tobacco
in ,the'. measuring chamber between these ex
tremes, the plunger, due to the action of spring
63, comes to rest before the end of the forward
swingof the link 55, and the ratchet 32 is set at
some point between its full line and dotted posi
tions shown, to stop the gate 9' in a position of
intermediate pocket depth.
‘
In this manner the ‘capacity of the feed pocket
is continuously and automatically regulated, ‘
wherefore excessive variation in the amount of
tobacco in the measuring chamber is prevented.
It should be understood, however that by replac
ing the multi-tooth ratchet segment 32 with a
two-tooth ratchet segment the present tobacco
feed will operate to stop the gate 9 in the position
of either maximum or minimum‘ pocket depth,
‘depending on the amount of tobacco in the meas
uring chamber, and deliver either the maximum
or minimum quantityof tobacco to the measuring
chamber. A suitable modi?ed form of pawl-and
ets or “bridging” in the remaining tobacco and
ratchet mechanism for this purpose is illustrated
assuring accurate measuring; and also serving to
loosen the tobacco‘in the hopper. In its closed
position 13' the blade extends well beyond the
in Fig. 3, wherein the pawl 49 engages the ratchet
tooth 320 following the extreme displacement of
the ‘?nger 48 (Fig. 1) resulting from depletion of the column of tobacco in the‘measuring chamber

‘
i The trapdoor 61 is fastened to an arm 14 hinged
on the pin 75 and actuated by a link 16 connected
to one arm of a lever 11 fulcrumed on a shaft 18
and tensioned by a spring 19, connected’to ‘the
(35 other arm of the lever Tl, a screw .83 on lever ‘ll
engaging with a pin 8! in' a bell-crank 82 fastened
on shaft 18 and connected to ‘a cam lever (not
shown) on shaft 54 by a rod 83-. There is also
fastened on shaft 18 an arm 84 carrying a pawl
.85 which engages with a ratchet 86 on a sprocket
. 8i‘! loose on shaft 18, this sprocket being thereby
“ intermittently driven during the downstroke of
rod 83, and in turn driving a system of agitators
‘ (not shown) arranged within the hopper 5, to ?ll
75 the feed pocket with tobacco. A pawl 88 pivoted
and thereby maintains the ratchet segment in a
position wherein its face 32a will check the re~
turn motion of pin 31 on arm 33 and thereby lim
it to a ‘minimum the upward movement of the
gate 9 from its initial or lower position. In the
event that the displacement of the finger 48 is
su?icient only to permit the pawl to drop into
the ratchet tooth' 3211', the ratchet segment will
permit the gate to swing up to position 9". Dur (i5
ing the forward motion of gear 25 its pin 38 en
gages the pin 31 on the arm 33 backward in the
same manner as described above to move the
gate 9 into its lower position at the bottom of the
pocket. During the return motion of gear 26 the 70
pin 31 on arm 33 is checked by the ratchet seg
ment, which has previously been set by engage
ment of the pawl with ratchet tooth 320 or 322), to
halt the gaté'in position 9 or 9" respectively.
Therefore a maximum or minimum quantity of
4
2,130,765
tobacco will be delivered when‘ the gate swings
to its dumping position.
'
In Fig. 2, an arrangement of the measuring
chamber for making tapered bunch charges is
shown. The top of the chamber 6|] and the trap
door 6! are straight, but the mid-section of the
bottom 89 thereof is bent to the desired taper and
has straight margins parallel with the door 6|.
On these margins are slidable the end walls 90
10 which are fastened to stems 9i passing through
the'stationary side plates 92. After adjustment
for the length of bunch desired, the end walls 90
are secured in place by set screws 93 threaded in
the side plates 92 and engaging the stems 9|.
15 The face 52 of the compression plunger, which
consists of a felt pad held between two metal
plates, is shaped to ?t the tapered cross-section
between the end walls 90 and is attached to a
head 94 in which the shank 5| is fastened. If
20 desired, the charge-measuring pocket 62 may be
provided with a similar cross-section.
After the charge-measuring pocket has been
?lled with tobacco compacted to the proper densi
ty, the bunch charge ?lling the same is severed
25 from the column of tobacco by the knife K, actual
ated by any suitable mechanism such as shown
in my c'o-pending application identi?ed above
or the above'mentioned patent, and the pocket
is‘ lowered and turned by mechanism, also shown
30 in said application, to deliver the‘ severed‘bunc‘h
charge to the bight of the bunch rolling apron.
It should also be understood that the feedpock
et is adapted to portion ‘small, as well as large
scrap tobacco and can also be used for measur
35 ing comminuted materials and other materials
such as grain.
