HARVESTER-THBESHER
Walter G. Charley, Brighton‘, Victoria, Australia,
assignor to Allis-Chalmers Manufacturing
Company, Milwaukee, Wis., a corporation of
Delaware
Application August 10, 1935, Serial No. 35,584
Renewed December 17, 1936
26 Claims.
This invention relates in general to improve
ments in threshing machines of the class gener
ally known as harvester-threshers or combines
. wherein the mechanism for harvesting grain or
5 like crops is combined in a single apparatus
with the mechanism for threshing and separat
ing the threshed grain or. the like from the straw
or stalks.
It is a general object of the present invention
10 to provide an improved harvester-thresher or
combine of simple and compact design and capa
ble of emciently handling a wide‘variety of crops
under various growth and other conditions and
which is of relatively small weight and size and
low power requirements, thus permitting the ap
paratus to be manufactured at relatively low cost
and to be e?iciently operated at relatively high
speed and capacity with minimum power require
ments.
20
It is a further object of this invention to pro
vide a harvester-thresher of simple and improved
design and construction wherein the grain sev
ered by a cutting sickle may be conveyed directly
to a threshing cylinder of a length substantially
the same as the e?ective length of the sickle
and wherein the material discharged from the
threshing cylinder passes to a separating mech
anism wherein the material is advanced, during
tion wheels II and extending transversely of the
normal direction of travel of the apparatus. On
this tubular support In is mounted an auxiliary
supporting structure of a fabricated character and
including a forwardly projecting fabricated frame 5
I2 serving as a drawbar support through which
tractive effort of a source of traction, such as a
power tractor, may be applied through a suitable
coupling at the forward end of the frame l2, and
as a support for a power shaft through which
power is supplied from a tractor for operating
the several mechanisms of the apparatus, and a
framework on which are carried several major
elements of the apparatus, such as the support
ing and enclosing housing H for the threshing
mechanism, with the auxiliary header frame l4
carried by the latter housing, and the separator
housing 15 communicating with the discharge
side of the thresher housing litand~ extending
transversely thereof, and a storage bin l6 for
clean grain. ’ The position of the traction wheels
and their journals and the design of the parts
of the machine are such that the weight of the
harvester-thresher is balanced about the axis of
rotation of these wheels.
~
In the accompanying drawings:
The header frame I 4 is of trough like form open
at its forward and rear ends and has side walls
I‘! which may be ?anged at their upper edges
throughout a portion of their length, particularly
the ?ange l8 on the outer side wall being of tapering curvature and acting as a splitter and guide
to deposit cut grain on the header frame. The
sidewalls ll of the header frame ?t closely with
in side walls 89 of the housing It for the thresh
ing mechanism at the open forward side there
of, and the header frame is mounted on the
housing l3 through a pivotal connection between
the side walls of the header frame and the side
walls of the housing l3, so that the lower for
ward edge of the header frame which carries the
cutting sickle may beswung upward and down
ward to a desired position of adjustment relative
to the ground.
The header frame may be actuated to desired
position of adjustment relative to the ground by
means of a rod 26, preferably pivotally attached
at its lower end to a laterally extending ?ange or

the separating action on the material, in a di
rection parallel to the axis of the threshing cyl
inder and transversely of the direction of the
travel of the machine and may be discharged from
the separating mechanism at a point laterally
outside of the apparatus.
.
It is a further object of this invention to pro
vide an improved harvester-thresher of the
aforesaid character wherein the apparatus may
be mounted on and the weight thereof substan
tially balanced about a single pair of traction
wheels.
These and other objects and advantages are
attained by the present invention, various novel
features of which will .be apparent from the
description and the accompanying drawings, dis
' closing an embodiment of the invention, and will
be more particularly pointed out in the claims.

mounted on the drawbar frame 12. Suitable
,
'
Fig. 2 is a sectional view in the plane of the
line 11-11 of Fig. 1.
Referring to the drawings, a main support’ for
the apparatus may be in the form of a steel tube
55 iii carrying journals for the supporting and trac
actuating mechanism, preferably including a bal~
ancing spring or other device to balance the
weight of the header frame about its pivotal
point, may be associated with the operating rod
[3 LI
2,128,879
25 to facilitate ready and easy actuation of the
header frame up and down to desired operating
position of the forward edge of the header frame.
At the forward end of the header frame l4
adjacent the bottom plate thereof is mounted a
sickle device 38 of conventional design, as in the
form of’, relatively movable cooperative serrated
cutting knives, and an actuating rod 3| for said
sickle device is pivotally attached to an actuating
10 plate 32 pivotally mounted on the laterally ex
tending plate 23 carried by the inner side wall
of the header frame.
“
A shield or guard 34 of generally rounded and
forwardly tapering shape and open at its rear
15 side is attached to the lower end of the inner side
wall of the ‘header frame and the plate 23, and
serves to protect operating mechanism, such as
the header frame actuating rod 2i and sickle
actuating plate 32, and also serves to guide grain
toward the sickle. The outer side wall of the
header frame may be extended, by an integral or
separately secured portion, in advance of the
inner side wall of this frame, and preferably is
shaped to provide a curved and forwardly taper
25 ing surface, as indicated at 35, the structure
forming a relatively smooth surface splitter
which enters the standing grain and serves to
lift and gather fallen grain and move the same
toward the sickle.
30
Mounted within the header frame adjacent the
lower edges of the side walls thereof is a travel
ing conveyer 38 of the draper belt type, prefer
ably provided on its outer or working surface
with cross bars or strips serving
35 hold loose grain. This belt is of
to substantially the full length of
vice, and it travels over a driving
to catch and
a width equal
the sickle de
roller 39 hav
ing shaft journals rotatably mounted in bearings
on the side walls I‘! of the header frame near the
40 upper end thereof and on the adjacent portions
of the side walls l9‘of the housing l3, the driv
ing shaft of this upper roller preferably being
coincident with the axis on which the header
frame has its pivotal movement on the side walls
45 of the housing l3, and projecting through the
outer side wall IQ of such housing.
The lower or foot roller 40 about which the
draper 38 travels, has shaft extensions in bear
ings on the side walls of the header frame.
A rotatable gathering reel is mounted on the
50
header frame in operative position relative to the
sickle and the traveling draper. This reel in
cludes a rotatable shaft 42 and a pair of spaced
sets of reel arms, each set including four arms 43
55 disposed ninety degrees apart and suitably at
tached to the shaft 42 for rotation therewith. A
paddle or bat 45 is attached to the two corre
sponding arms 43 of the two sets, at their outer
ends and along the leading edges of the arms.
60 The reel shaft is rotatably supported in suitable
bearings or a single bearing of extended length,
a bearing housing 46 being shown as of such
extended length as to provide for the support
and rotation of the reel shaft, this bearing sup
65 port being suitably carried upon an adjacent por
tion of the header frame_and preferably being
mounted thereon so as to permit both up and
down and fore ‘and aft adjustment of the posi
tion of the bearing, to thus provide for adjusting
70 the position of the reel with respect to the cutting
sickle. In the operation of the reel, the reel arms
and the paddles or bats carried at their outer
extremities move in an anti-clockwise direction,
considering Fig. 2 of the drawings. As the
75 paddles are carried to their lowermost position,
the uncut grain is carried or urged forward by
the paddles and presented to the sickle, and
thereafter the cut grain is deposited by the
paddles on the conveying draper 38.
An endless feeding conveyer 43, in the form of
a draper belt preferably provided with transverse
bars or slats on the working surface thereof, is
driven by a driving roller 49'and travels over a
second roller 50 disposed above and somewhat
beyond the upper roller 39 of the conveying 10
draper 38. Shaft extensions of the rollers 49 and
59 are mounted in bearings in the side walls I9
of the housing l3, the shaft 5| of the driving
roller 49 passing to the outer side of the outer
side wall IQ of the housing l3. The rollers 49 and
50 are so positioned and the feeding draper 48
is so driven that the lower course of the latter
draper travels, like the upper course of the con
veying draper 38, toward the threshing mecha
nism in the housing l3, and the working surfaces 20
of the two drapers gradually approaching each
other to produce a throat or restricted area over
the upper roll 39 of the draper 38. The lower sur
face of the draper 48, particularly at its inner
end, is adapted to press against and advance
material which has been fed along and by the
working surfaces of the draper 38, and this feed
ing of material is facilitated by having the linear
speed of the upper draper somewhat greater than
that of the lower draper. v
30
The threshing cylinder, indicated generally at
52, comprises’ an operating shaft 53 and an
open-work frame structure 54 of generally cylin
drical outline including a plurality of peripheral
ly spaced thresher bars 56 in the form of sections
of angle iron, radially extending ?ange portions
of the bars serving as active threshing elements.
The stationary concave element with which the
thresher bars cooperate in the threshing opera
tion includes a generally circular housing portion 40'
51 beneath the threshing cylinder and a throat
or ledger plate assembly at the forward edge of
this housing portion, this assembly comprising-a.
bent-plate portion 58 associated withthe bottom
wall of the header frame and having its rear 45
edge projecting beyond the adjacent forward
edge of the cylinder housing. An adjustable
choking or ledger plate 59 is mounted and se
cured in position at the rear edge of the bent
plate 58 and extends beyond the same and over 50
the forward edge of the cylinder housing, into
relatively close proximity to the path of the ro
tatable threshing elements. Through the ad
justable mounting of this ledger plate, its rear
edge may be moved toward and from the thresh
ing cylinder, thus most efficiently accommodating
for wear of the rear edge of the ledger plate and
for diverse characteristics of various crops to be
threshed, particularly as to the 'size or character
of the grain kernels or seeds and the stalks.
On the upper surface of the bottom of the con
cave housing 51, bars or strips 6| are provided,
these latter extending generally parallel to the‘
axis of the threshing cylinder and projecting'into
relatively close proximity to the path of the
thresher bars 56. These bars or strips may be
in the form of raised portions of the housing or
in the form of bars secured to the housing.
The upper portion of the housing for the
threshing cylinder follows and is relatively closely 70
spaced from the path of the threshing bars 58 to
a point adjacent the end of the upper feeding
draper 48.
I
The bearings for the shaft 53 of .the threshing
cylinder may be mounted, in a conventional man 75
,
active ‘threshing portions of the concave. With
such an arrangement, the space between the
path of travel of the rotating threshing bars and
the concave threshing projections may be varied
to best facilitate the passage of the various kinds
of threshed grain or seeds and the stalks of the
crop.
The lower portion 51 of the cylinder housing
10 may be perforated adjacent the threshing or
stripper bars 6| so as to permit threshed grain
to pass therethrough from the housing, whence
such grain may be conducted to the grain pan
_- of the separator, or the housing may be substan
15 tially imperforate, as indicated, in which case all
of the threshed grain is forced through the hous
ing and is discharged therefrom, along with
the straw or stalks, through the discharge pas—
sage 63 into the separator housing l5, and drops
20 on the shaking devices therein.
The discharge opening or passage 63 extends
across the full width of the threshing cylinder
and opens into the forward portion of the sep
arator housing l5 through the adjacent wall
25
thereof.
As indicated, the separator housing I5 ex
4 tends from one end of threshing cylinder housing
past the other end thereof and to an extended
distance beyond to the other side of the machine.
30 And the housing I5 is provided with devices for
shaking the straw and recovering threshed grain
therefrom, these devices including a straw shak
ing rack 65 extending the full length and ap
proximately the full width of the separator hous
35 ing.

2,128,879
ner, so as to be adjustable toward and from the
This shaking rack may be of known or
conventional slatted type which permits the
grain to fall through the rack between the slats
thereof, and advances the straw along the rack
to the discharge end whence it is carried or blown
to the ground at a point laterally beyond the
machine.
.
The straw rack is mounted in operative posi
tion to provide for the desired oscillating or
shaking motion through a conventional form of
of air is induced along the normal path of ?ow
of material passing through the threshing mech
anism, and this induced draft assists in forcing
the straw and threshed grain from the housing of
the threshing cylinder toward and through the
discharge passage 63 therefrom to the separator
5
housing I5, keeping the cylinder clear.
The straw and grain deposited upon the for
ward end of the shaking rack is, through the
normal shaking action of the rack, advanced
rearwardly along the rack, that is, in the direc
tion of discharge from the separator housing, the
grain, along with relatively short pieces of straw
falling through the spaces between the slats of
the rack as the straw is advanced. The straw 15
continues to advance over the rack and to the
discharge end thereof, and it is forced over the
discharge end directly into the ?eld or is con
veyed through a suitable rigid or ?exible conveyer
to a desired point of discharge, such discharge 20
being assisted by the air discharging through the
separator housing.
During operation of the separating mechanism,
threshed grain and some chaff dropping through
the apertures in the rack, fall onto the grain pan, 25
the major portion of which is formed by the bot
tom plate ‘H of the separator housing. A grain
drag or rake 12 of conventional design is pro
vided within the separator housing below the
straw rack; and the material ‘falling through the 30
straw rack is carried along the bottom of the
grain pan to a suitable point of discharge there
from to a cleaning device 14. This cleaning de
vice may be disposed in a housing extension de
pending from the separator housing, and the 35
cleaning device may be of conventional'form in
cluding a plurality of superposed and inclined
screens ‘I5 with means for imparting a vibrating
motion thereto, to permit the cleaned grain to
pass through the screens and unthreshed heads 40'
to move toward and across the rear edges of the
screens, ventilating means, of conventional form,
being provided to facilitate the cleaning opera
ing or shaking motion being imparted to the rack
tion, particularly by way of carrying away small
particles of dirt and dust.
45
Threshed and cleaned grain passing through
through oscillation of such shaker arms, such a
the/‘cleaning device is carried by a conveyer ‘I6
shaker arm being indicated at 68, and an op
and a suitable elevator, not shown, associated
therewith to the grain bin. The tailings or larger
particles of straw and unthreshed grain heads 50
rejected by the cleaning screens drop into the
45 link and shaker arm support, the desired vibrat
erating eccentric and connecting rod therefor at
50 ‘it and 69 respectively.
In the operation of the threshing mechanism,
the harvested grain is moved upwardly along the
conveying draper 38 toward its discharge end
where the feeding draper Q8 cooperates in mov
ing the grain toward the threshing mechanism
and into the path of travel of the threshing
bars 56, and the latter, moving at a relatively
high speed, beat the grain kernels from the
straw and force or draw the threshed grain and
60 straw between the threshing bars and the rear
edge of the ledger plate. During this ‘operation,
the heads of grain are forcibly projected against
the rear edge of the ledger plate and then car
ried beyond the same by the rotating threshing
bars,
the latter carrying the grain and straw past
65
the threshing bars of the concave, the coopera
tive movable and ?xed threshing bars serving to
beat grain from the heads as the latter and the
straw are passed through the space between the
70 cylinder and the concave.
Due to the fact that there is considerable fan
action of the rapidly rotating threshing cylinder,
particularly with the lower portion of the cylin
der housing substantially closed, the threshing
75 bars acting as fan vanes, a considerable current
casing of a conveyer ‘I8 and are carried thereby
to an elevator ‘19 extending toward the threshing
cylinder and with its discharge‘ end or spout
above the cylinder.
-
1
The tailings drop from the discharge end or
55
spout of the elevator 19 to a trough like housing
or conveyer 8! having a downward inclination
toward the left hand side of the machine as
viewed in Fig. l, to facilitate movement in that 60
direction, whence they discharge, through a spout
82 to a chute 90 opening into the forward side of
the threshing cylinder housing,'where this dis
charged material may be subjected to a further
threshing operation. Preferably, this conveyer 65
8! extends to the end‘ of the cylinder housing
opposite the forward end of the separator hous
ing and the tailings are preferably discharged to
the cylinder housing adjacent this end, so as to
permit such tailings, after the threshing action 70
thereon, to be subjected to a separating action
throughout the full length of the separator. And
this conveyer Si is preferably provided with a.
screen 83 extending the full length of the hous
ing and onto which the tailings are discharged 75
4
' ‘2,128,879
from the elevator 19. As the tailings pass along
the screen to the discharge end of’ the conveyer,
the conveyer acts as a recleaner, particles of
clean grain dropping through the screen; and
these latter may be carried by a separate dis
charge spout 84 to a chute 85 leading to the
grain pan of the separator.
The cleaning action as the material passes
over the screen 83 may be supplemented by im
10 parting a shaking or vibrating motion to the hous
ing of the conveyer 8|, by mounting the housing
on a pivoted link support and- connecting the
linkage or the housing to a shaking device, such
as a shaker arm 68.
v20
The grain bin I6 is mounted on the frame
structure and the support ill in a position at the
side of the housing for the threshing mechanism
and in front, in the direction of travel of the ma
chine, of the discharge end of the separator hous
ing. The bin is of such design and so located that
its weight and the weight of material contained
therein is balanced about the axes of the sup
porting traction wheels.
'
Power for operating the various mechanisms of
the apparatus is derived from a main power shaft
made up of longitudinally adjustable sections 85,
86. The forward section 85 is provided with a
spherical journal portion 81 rotatably supported
30
in a spherical bearing 89 which is pivotally
mounted on the forward end of the drawbar frame
I! to move in a plane extending in the general
direction of the axis of the shaft section 85. The
shaft section 85 is connected through a double
shaft 98; and power for operating the eccentric
‘I0 which produces the shaking motion of the
rack, and for vibrating the cleaning device 14
and for actuating the conveyer ‘I8 and the re
cleaning conveyer 8| and the elevator 19 is pref
erably derived from the shaft 98.
The reel shaft is preferably driven through a
driven pulley thereon and a power connection
thereto from one of the traction wheels of the
apparatus. This arrangement insures a proper 10
speed of the gathering reel independently of the
speed at which the apparatus travels over the
ground, or the speeds of operation of the sickle
and threshing and separating mechanisms.
With the arrangement described, as to the 15
threshing cylinder being of substantially the same
length as the sickle, and the feeding of the cut
grain to the cylinder over an extended length in
a relatively thin stream or'band, the threshing
cylinder may operate at high speeds without 20
choking, thereby improving the threshing action
and increasing the capacity of the machine; and '
as the grain stalks are presented to the cylinder
longitudinally, i. e., in the direction in which they
fall on the feeding draper, without any turns in 25
its path from the sickle, the stalks pass through
the threshing mechanism without packing or
bunching, and there is relatively little breakage
of straw, a feature which improves the separat
ing and cleaning action. With the separator 30
housing arranged transversely of the direction of
travel of the grain from the sickle and through
the threshing mechanism, and disposed in the
rear of the latter and the grain bin, a machine
with very small fore and aft dimensions, and 35
with suitable provision for up and down adjust-'
to the rear end of a power shaft 93 carried by a
tractor, not shown, this power shaft preferably ment of the header frame and sickle, is possible;
being operable at speeds independent of the and the expense of providing a complete ma
chine, with the weight thereof balanced about the
speed of travel of the tractor.
