stem of the leaf will pass without being
crushed as it is being carried forward to the
rollers, the grooves being arranged at the cen-
ter of the rollers, so as to be substantially in
5 alinement with the disks or cutters, whereby
they may assist in guiding the stem in be-
tween the cutters. The belt 26 is preferably
a trifle shorter than the belt 20, so as to leave
a small portion of the forward end of the
to lower belt exposed for the convenient inser-
tion of the leaf between the two belts.
The lower shaft 7 is preferably provided
with a drum or roller 28 upon each side of the
cutter, upon which is mounted a belt 29, the
15 rear end of which passes over a roller 30 at
the rear end of the table. Two rollers 30, one
for each side of the table, are mounted upon
a shaft 31, which is journaled at its ends in
brackets 32. The brackets preferably extend
20 beyond the rear of the frame, so that the belt
will deliver the leaves at a sufficient distance
from the frame 1.
Secured at the inner or adjacent edges of
the sections 3 are longitudinal rods 33, upon
25 which are secured :strips or pieces of wire-
gauze or other suitable material. There are
two rods for each section, one at the top or
above the same and the other at a suitable
distance below, so that the woven wire upon
30 the two sides will form a passage-way through
which the tobacco-stems are delivered after
coining from between the rollers without be-
coining entangled with the belts or portions
of the leaf carried thereby.
35 As is well known, the gum from tobacco-
leaves is apt to collect upon the knives or cut-
ters and prevent their running close enough
together to cut the- leaf without danger of
tearing it. To obviate this difficulty, I pro-
4o vide my machine with a scraper or cleaner
for each cutter, as shown fully in Figs. 5 and
6, to avoid confusion in other views. The
cleaner for the upper cutter is formed from
a plate of metal 34, which has one edge pro-
45 vided with a notch or recess 35, by means of
which the plate is adapted to fit down over
the upper portion of the cutter, so that the
portion of the plate at the bottom of the re-
cess will engage with the periphery of the
50 cutter and the sides will engage with the sides
of the cutter. The cleaner for the lower cut-
ter is formed in the same manner from a plate
36, one edge of which is provided with two
recesses 37, through which pass the knives or
55 cutting-blades forming the sides of said cut-
ter. These cleaners are preferably support-
ed by brackets 38 and 39, carried by the frame,
as shown. By providing cleaners for the cut-
ters in this manner the gum from the leaves
6o will be scraped off the cutters as rapidly as it
accumulates, and thus permit of the cutters
running in close contact at all times, so as to
cut the edges of the leaves from the stems
without danger of tearing or mutilating the
65 leaf in any manner.
In using my machine the leaves of tobacco
are smoothed out upon the table in front ofthe machine and are then fed in between the
forward belts one at a time with the stem of
the leaf arranged in substantial alinement 70
with the cutters. The wide belts will then
engage with the leaf and feed it forward un-
til the stem is caught between the rollers,
which will further assist in feeding the leaf
forward. As soon as the leaf has passed be- 75
tween the cutters the stem will be delivered
through the passage, between the rear sec-
tions of the table, while the sides of the
leaves will be carried forward by the belts ar-
ranged between the cutters and the sides. In 8
this manner the leaves can be rapidly stemmed
and delivered ready for subsequent use. By
means of the temper-screws at the ends of
the shafts any desired amount of pressure be-
tween the cutters may be secured and the ma- 8
chine be thereby adapted for different grades
or sizes of tobacco-leaves. The machine is
strong and compact and can be readily se-
cured in position by any ordinary means and
power applied from any convenient source. 90
Although I have shown what I consider the
most desirable form of constructing my im-
proved tobacco-stemming machine, yet I re-
serve the right to make such changes and al-
terations therein as- will come within the 95
scope of my invention.
Having thus fully described my invention,
what I claim as new, and desire to secure by
Letters Patent, is-
1. In a tobacco-stem ming machine,the com- roo
bination, with a frame, of cutters arranged
therein, a wide delivery-belt in front of the
cutters and two discharge-belts to the rear
thereof the belts at the. rear being spaced
apart and the cutters being located between 105
them, substantially as described.
2. In a tobacco-stemming machine,the com-
bination, with a frame, of cutters journaled
therein, a wide belt in front of the cutters,
two narrower belts at the rear thereof the i10
belts at the rear being spaced apart and the
cutters being located between them and
guards adjacent to the rear belts, substan-
tially as described.
3. Ina tobacco-stemming machine,thecom- 115
bination, with a frame, the top of which is
formed in sections, of cutters journaled be-
tween the front and rear sections, a belt for
each section, said sections, each lying between
the upper and lower plies of its respective 120
belt, and a belt journaled above the belt over
the forward section, substantially as de-
scribed.
4. In a tobacco-stemming machine,the com-
bination, with a frame, the top of which is 125
provided with a wide section in front and two
narrower sections at the rear, the rear sec-
tions being at a slight distance from each
other, of cutters journaled between the rear
sections at their forward ends, the contacting 130
edges of the cutters being substantially even
with the top of the table, a belt for each of
the sections each section'lying between the
upper and lower plies of its respective belt,2
