ANDREW J. BUSH, OF KAUFMAN, TEXAS, ASSIGNOR OF ONE-HALF TO A. C.
GREEN, OF PALESTINE, TEXAS.
TOBACCO-STEMMING MACHINE.
SPECIFICATION forming part of Letters Patent No. 694,130, dated February 25, 1902.
Application filed July 7, 1900. Serial No. 22,844. (No model.)To al wzhoim it imay concern:
Be itknown that I, ANDREW J. BusH, a citi-
zen of the United States, residing at Kauf-
man, in the county of Kaufman and State of
5 Texas, have invented a new and useful To-
bacco-Stemming Machine, of which the fol-
lowing is a specification.
My invention relates to tobacco-steinming
machines; and it has for its- object to pro-
1o duce a machine of this character which shall
be .simple, cheap, and efficient; and it con-
sists in the improved construction and novel
combination of parts of the same, as will be
hereinafter more fully set forth.
15 In the accompanying drawings, in which
the same reference-numerals indicate corre-
sponding parts in each of the views in which
they occur, Figure 1is a perspective view of
a machine embodying my invention. Fig.
20 2 is a top plan view of the same, and Fig. 3
is a longitudinal sectional view. Fig. 4 is a
transverse sectional view through the ma-
chine, showing the cutters in edge view, and
Figs. 5 and 6 are detail views illustrating the
25 cleaners for cutters.
In machines of this character it is neces-
sary that the leaf of tobacco to be operated
upon should be carried forward as rapidly as
possible and with as little danger of mutila-
30 tion as is consistent with rapidity and per-
fection of operation.
In the machine which I have invented I
provide a suitable framework 1, having a
smooth flat surface, upon which the tobacco
35 is spread and carried forward. The top of
the table is composed of sections the forward
one of which, 2, extends the whole width of
the frame and from the front portion thereof
nearly to the cutters, and the rear ones, 3,
40 extend from the cutters 4 to the rear end of
the frame and from the sides of the cutters to
the sides of the frame, respectively, a space
being formed between the sections for the
passage of the stems after the leaf has passed
45 between the cutters. A suitable feed-board
5 projects forwardly in front of the frame for
the reception of the leaf before it is fed into
the machine.
The cutters comprise two rotary disks 6,
So which are secured to the central portion of
the shafts 7, the ends of which are journaledin bearings 8 at the sides of the machine.
The shafts are arranged one above the other,
with the contacting edges of the disks or the
cutters substantially on a line with the top 55
of the table or machine. The disks may be
of the ordinary grooved construction with the
edges of one overlapping the edge of the
other, so that the stem or mid-rib of the leaf
may pass through the grooves,while the sides 6o
of the leaf will be severed therefrom by the
overlapping portions of the cutters. The
cutter-shafts are preferably provided with
intermeshing gear-wheels 9 at one end and
may be driven from any suitable source of 65
power-as, for instance,the driving-wheel 10.
The bearings for the upper roller are pref-
erably made adjustable by means of the tem-
per-screws 11, which are:screwed down through
the tops of the brackets 12, within which the 70
bearings of the shafts are located.
A shaft 13 is journaled transversely across
the front end of the machine by means of
brackets 14 and is formed or provided with
a roller 15. One end of the shaft projects be- 75
yond its bearing and is provided with a pul-
ley 16, by means of which it'is driven by a
pulley 17 on the lower feed-shaft 7 through
the belt 18. A roller 19 is journaled trans-
versely across the frame between the inner 8o
end of the forward section 2 and the cutters.
A wide belt 20 runs over the rollers 15 and 19,
with a portion thereof moving on top of the
table and a portion below, the portion of the
belt on top moving toward the cutters. 85
Journaled on top of the frame by means of
brackets 21 are two rollers 22, the shaft of
the forward one of which extends beyond. its
bearing and is provided with a. pulley 23.
The pulley 23 is driven from a pulley 24 on 90
the upper shaft 7 by means of a belt 25. A
belt 26 passes over the rollers 22 with its end
portion arranged to travel toward the cut-
ters and in such close proximity to the upper
portion of the belt 20 that a leaf of tobacco 95
will be firmly gripped between them and car-
ried forward. The belts 20 and 26 are wide
enough to extend substantially from one side
of the machine to the other, so as to carry
forward the largest-sized leaves. If desired, oo
the rollers over which the belts pass may be
provided with grooves 27, through which the
