the shaft 32. The teeth of the loosening mem
ber 3! swing closely adjacent the inner concave
surface of the plate 29.
It will be seen that the inner concave surface
tegrally secured to an arm 55.
It will also be
understood that in this modi?ed form of separat
the circular path of the tips of the comb prongs
or toothed plates 36, and the plate 29 acts as an
ing means either of the drums shown in Figures
1 or 4 with the grate bars of Figure 4 may be
used.
In the use and operation of this device the
tobacco is fed to the housing II] on the conveyor
l2 and compressed between the rolls I5, 23 and
24. The compressed layers of tobacco leaves
are loosened by the loosening member 3! which
has the loosening blades 36 secured thereto. This
loosened tobacco is then carried to the sepa
rating member 38 which turns at a faster rate
than the loosening member 36. The teeth 39 of
10 .an abutment 29a in line with the webbing or
abutment 22. The upper and lower rollers ll,
23 and 24, the member 28, bar 30 and abutment
29¢, suitably disposed from the abutment or bar
30, form a channel, which channel discharges
15 against the path of the tips of the combs 36, to
enable the combs 36 topull the leaf portions
close by the abutment 29a and along the inner
contour of the plate or concave 29.
'
A beating drum or member 38 having beating
20 teeth 39 is mounted on the shaft 40_journaled in
the housing l6 and the teeth 39 are so positioned
as to engage between the'teeth of the plate 36.
In this manner when the loosening member 3|
‘rotates as shown by the arrow in Figure 1 the
25 beating member 38‘will rotate in the direction
shown by the arrow in Figure l and will rotate at
a faster rate by reason of the belt 34 engaging a
relatively small pulley 4| which is secured to the
shaft 46. An idling pulley 42 is mounted on the
shaft 43 and one run of the belt 34 engages over
the pulley 42.
Disposed below the beating member 38 there is
positioned a grate member 44 which is sup
ported for adjustment toward or away from the
beating member 38 by means of slotted arms 45.
This grate member 44 comprises a plurality of
spaced apart bars 46 which, as shown in Figure 1,
are spaced apart at varying distances the distance
between the bars increasing in the direction of
40 the rotation of the beating member 38.
The slotted arms 45 are held in adjusted posi
tion by means of headed bolts or adjusting mem
the separating member 38 will throw the tobacco
toward the top of the housing I 0 and as this
tobacco falls down it will again strike the separat
ing member 38 and after several beating opera
tions the tobacco will be practically completely
separated as to the web from the ribs.
In many instances the ribs R, as shown in
Figure 3, will engage between the grate bars 46
and the web portions W will be torn oiT of the ribs
R. before the removed web portions are able to
drop between the bars or screening members 46.
It is obvious that various changes and modi?
cations may be made in the details of construc
tion and design of the above speci?cally described
embodiment of this invention without departing
from the spirit thereof, such changes and modi?
cations being restricted only by the scope of the
following claims.
What is claimed is:
1. In an apparatus for ripping raw tobacco
leaves, forwarding compressing means for con
veying the leaves, an abutment disposed in re
lation to said means to form with said means a
pressure channel, means for feeding tobacco
leaves into said channel and between said for
bers 41 which engage in horizontally disposed
warding
slots 48 carried by a bottom wall or frame piece
means at the outlet end of the channel acting
upon the leaves resting on the abutment form
49.
'
compressing
means,
and
loosening
When the loosened material drops through
ing the channel for loosening the leaf portions
the grate bars 46 the material will fall onto a
conveyor 50 which conveys the loosened ma
from the ribs of the tobacco leaves, said means
including comb prongs acting upon the com
pressed tobacco leaves perpendicularly to the
terial both web and ribs out of the housing ID.
50 A plate or hopper 5| is positioned inwardly of
the housing l0 so as ‘to prevent any loosened
material dropping through the grate bars 46
from passing forwardly and to retain this loos
cned material on the conveyor 50 until removed
by movement of the conveyor.‘
In Figure 4 there is shown a modi?ed form of
beating means wherein the beating member 38a
is disposed in a housing Ill,a similar to the hous
ing l0 and the grate. member or screen 44& is
positioned concentrically below the beating mem
ber 38*‘. In this modi?ed'form the grate bars 46“
are each separate one from another and are pro
vided with right angularly related opposite end
portions 52 through which bolts 53 extend. These
65
an improved form of tobacco loosening means in
the form of a toothed member 36‘) which is in
of the plate 29 is substantially concentric with
anvil to the tobacco moved along by the comb 36.
The upper end of the plate 29 is provided with
45
tion of this invention where the housing Illb has
bolts 53 engage through radially arranged slots
54 provided in the housing Illa. By means of the
individual adjustment of the grate bars 463
the desired retention of the material can be had
for beating by the beating member 381*. It will
70 be obvious that movement of the grate bars. 4Ga
toward the drum or beating member 38,a will re
duce the spaces between the grate bars and
movement awayfrom the beating member‘ 383L
will enlarge these spaces.
