THRESHING MACHINE FRAME
Hermann Raussendorf, Saxony, Germany

1'7 Claims.
This invention relates to frames forthreshing
machines in which the frame and supporting
beams are constructed of steel.
In the ordinary threshing machines as now
5 made a wood frame is provided resting upon lon
gitudinal beams supported by the chassis. Such
a construction, particularly when a straw press
is connected with the threshing machine, is sub
ject to twisting and tortion strains so tha t the
H o connections between the various struts and
beams are greatly strained and fail prematurely
or become loosened by friction, etc. Attempts
have heretofore been made to overcome these de
fects by providing the frame housing exteriorly
15. with triangular metal plates in projecting or
transverse beams as reinforcements, since it is
impossible to provide transverse reinforcements
at the interior of the housing with the exception
of a few points. It is an object of the present in
20 vention to eliminate all the drawbacks inherent
in constructions of the type mentioned.
Another defect in threshing machine fr ames
as at present made lies in the fact that a wood
frame is subject to a swelling and shrinking in
2 accordance with humidity and other factors and
this defect renders such a frame entirely
for use in tropical climates and also a
frame in such climates would be soon destroyed
by termites, etc. Attempts have been made in
3 O View of these conditions to construct a threshing
machine frame of metal, particularly sheet
metal, but such a construction has been no better
than the ordinary wood frames. It is the pur
pose of the present invention to overcome all
of the above named disadvantages of threshing
machine constructions.
With respect to the threshing machine fr ames
heretofore made of metal, it has been demon
strated in practice that such steel plate fr ames
40 which are made of relatively weak plate and
struts, beams or the like in order to reduce the
weight, are not suf?cient to withstand the great
strains which are placed upon them. As the re
sult of the strains to which this sheet metal C011
on. Cl
struction is subjected, the rivet connections and
nut and bolt connections, etc. are excessively
overloaded and particularly the inner par ts of
the threshing machine which are connected with
the wood frame are prone to become quickly in
capacitated due to the twists and turns to which
they are subjected. It is a further object of the
present invention to eliminate all such draw
backs.
In contrast to the constructions heretofore used
55
(Cl. 130-27)
the present invention proposes a completely new
method of constructing a threshing machine
frame in that two substantially U-shaped sup
porting yokes made of section beams, one lo
cated near the front and the other near the M
rear end of the threshing machine, are rigidly
connected with a metallic under-frame which is
strong enough to withstand the twisting and tor
tion actions set up. The arms of said U-shaped
section beams are extended upwardly and carry 10
the vertical lateral walls of the housing which in
turn consist of steel plates passing entirely
through and rigidly connected with the section
beams.
'
It is an object of the invention to form a frame
having three simple constructional parts, namely
the underframe, the U-shaped supporting yokes
and the side walls which, being supported by the
usual and necessary transverse connections or
beams, is completely rigid between the side walls 20
and the construction is such that the under
frame completely takes up all the strains which
may be exerted upon the frame.
It is an object of the present invention to se
cure a construction which will permit the rela
tive position of the frame to become changed
when the threshing machine is traveling over
rough ground or there has been an improper ad
justment or alignment of the set up threshing
machine. As the result of the construction ea
those parts of the threshing machine located
partly in the housing between the side walls and
partly upon the side walls are not subject to any
strain due to the turning or twisting of the
35
threshing machine.
It is an object of the invention to form the
underframe of a seamless drawn steel tube of
suitable diameter while the U-shaped supporting
yokes are made of section beams assembled from
individual suitably bent ?at steel strips.
It is a further object of the invention to pro
vide means connected with the underframe by
welding or the like forming a continuation ex
tending along the longitudinal center of the 45
threshing machine frame and in the form of a
vertical section beam of sheet steel to which the
transverse support on which the straw press
frame is mounted may be attached.
A still further object of the invention is to
mount the underframe by means of springs on the
steel axles and to support it relative to the axle
by a centrally mounted buffer spring.
A feature of the invention is to provide a con
struction whereby all parts of the frame may be
2
v2,106,123
interconnected rigidly as for instance by electric
welding.
With the above and other objects in view
which will become apparent as the description
proceeds, a detailed explanation of an exemplary
embodiment of the invention is described below
and illustrated in the accompanying drawings.

As illustrated in the cross section of the yoke
shown in Figure 4 the yoke 9 has a U-shaped
cross section which is formed or assembled from
three sheet metal strips I3, Ill and I5 which are
electrically welded together. This cross section
then changes into the same I-shaped beam as
used in supporting yoke 8 at the lower portion 10
thereof and such construction is made by elec
trical welding three suitably bent sheet metal
strips such as ill, II and I2. In this case also

As above described, it is obvious that all the
parts of the threshing machine frame consist of
sheet steel and are interconnected preferably by 30
electric welding. Any twisting or tortion‘turn
which may arisecan be completely taken up by
the underframe I which is sufficiently strong to

strains or twisting strains are substantially low
ered or weakened due to the spring 5 and the
leaf springs ‘I. It is obvious that therefore due
to the construction described the parts of the
threshing machine located between the walls I6
and I‘! of the frame are not effected by the 40
twisting or turning moments since the parallel
spacings of the walls I7 and I8 is constantly
maintained and ensured.
The walls IB and H are provided with suitably
shaped notches, depressions or cut-away por 45
tions for suspending the well known spring pins,
the springs 2i and 22 of which carry the shaker
and the back travel floor. These springs are
attached at their upper ends to the projectiohs
23 of an angle bar 24 by bolts or screws and the 50
like. The angle bar 24 is attached by the upper
edge exteriorly on the side wall plate I6 and/or

Referring to the drawings, the underframe
consists of a seamless drawn steel tube I which
is located centrally between the wheels 2 and 3
and extends obliquely to the rear, being inclined
at the end of the threshing machine at which
the sheet steel frame of a straw press S may be

near the rear end in the vicinity of the axle 6
and the yoke 9 is provided near the front end
in the vicinity of the axle 4. Referring to Fig
ure 3 the supporting yoke 8 is- of I-shape cross
section. vSuch cross section is formed by bend
ing the three sheet metal strips, III, II and I 2
to the required yoke form and then welding them
together electrically or securing them together

by any other desired means.v The plates I0 and
I2 going from one side of the threshing machine
to the other are closely applied to the periphery
of the tubular underframe I and are connected
therewith by electric welding or otherwise.
The
web of the I-frame is cut away in the manner
shown particularly in Figure 2 so as to abut
threshing machine frame.
This wood platform
may be retained since a metal platform does not
provide a sure foothold for the workers and also
because this frame is not subject to the strains
previously mentioned.
Combined with the threshing machine frame 65
is the metallic straw press frame, themain por
tion of which forms the passage 29.
The as
semblage is constructed in the following man
ner, particular reference being made to Figures 5
to 8 inclusive.
'
A sheet metal member 39 is provided extending
at its end 3| into the tubular underframe I to
the inner wall of which it is electrically welded
70
(see particularly Figure 7). The member 30 thus
forms a projection or continuation extending 75

along the central longitudinal line of the thresh

85
ing machine frame. The member 39 is rein
forced at its lower edge by an arcuate ?ange 32
welded to the metal member 39 as shown in Fig
ure 8. At the free end of the member 36 the
angle members 33 are attached at both sides by
means of welding. These angle members form
supporting means for a transverse support 34
which is of U-shape and is secured as by bolts
and nuts or by screws to the angle members.
Other supports also in the form of welded angle
members 35 are provided at about the center
of the member 36 at the upper edge thereof. A
transversely extending beam 36 in the form of an
angle bar or rail is screwed to these supports.
The floor 31 of the straw press passage 29 is
mounted upon the transverse supports 34 and 36.
A transverse beam or support 38 having a U
shaped cross section is welded to the under side of
the steel tube I near the end at which the mem
ber 36 is secured. For increased reinforcement
the sheet metal members or plates 39 are welded
to the tube I and to a ?ange 40 of these members
the transverse support 38 is attached by the
screws 4|. Secured to the ends of the transverse
support 38 as by welding, are the vertical plates
42 having a ?ange construction 43. To each one
of these plates 42 there is screwed or bolted a
buttress-like or strut-like plate 44. The plates
44 extend upwardly and are welded to the corre
sponding lateral cheeks of the straw press pas
sage 29. As will be noted, the metallic straw
press frame is in this manner connected by a
simple supporting rib structure with the frame
of the threshing machine so that any tortion
is precluded. In this construction also all the
parts as well as the section beams may if desired
be made of steel plates which are welded together.
On the underside of the sheet metal extension 30
40 there is welded an arm 45 having a perforation
46 whereby traction hooks, swingletree hooks or
the like may be ‘attached in case the threshing
machine-straw press unit is to travel backwards.
The spring suspension of the threshing machine
45 frame is constructed in the following manner.
The front axle 4 consists of a box-like housing
which is formed by a metal plate 48 with a
channel-shaped member 4‘I. On both sides of
this housing the axle spindles 49 for the front
50 wheels 2 are attached by welding. The front
axle 4 constructed as a box-like housing above
described is engaged at about its central portion
by a U-shaped saddle or yoke 56 which is rotat
ably mounted with respect to the axle 4 by means
55 of the pivot pin 5I. A tube or bearing 52 is
welded in the center of the axle housing 4 and
two plates 53 are welded upon the interior faces
of the legs of the U-shaped yoke 56 in order to
reinforce the bearing points.
Secured by welding to the U-shaped yoke 56
60
is the pivot pin 54 whose upper end enters a tube
55 which is welded in the steel tube or under
frame I which is somewhat ?attened at the front
end. Surrounding the pivot pin 54 is the conical
65 buffer spring 5 resting upon the disk or plate 56.
Interposed between the disk 56 and the U-shaped
yoke 56 is the housing member 51 which is shoul
dered in the manner shown in Figure 9 and se
cured to the pivot pin 54 by means of the trans
70 verse pin 58.
A substantially U-shaped supporting yoke 59 is
attached to the underframe I near the location
of the pivot pin 5-4. The yoke 59 has a horizontal
portion 59’ which is reinforced by a plate 66
75 through which the housing member 51 extends.
3
The pivot pin 54 therefore serves as the pivot pin
for the front axle. A reinforcement plate BI is
also provided being welded upon one hand to the
underframe I and on the other to the yoke 59.
Bars 62 are welded to the front axle 4 and
carry at their free ends a collar-like yoke 63 for
inserting a thill, pole, beam or the like. Two
V-shaped abutting bars 64 being welded on one
hand to the axle 4 and on the other to the yoke
10
63 serve to reinforce the same.
The rear axle 6 also consists of a box-like hous
ing in the ends of which the axle spindles 65 for
the rear wheels 63 are secured as by welding.
The supporting yoke 8 disposed above the rear
axle 6 is supported by the two sets of leaf springs 15
‘I which are secured to the yoke 8 by means of
the shackle bolts 65. The ends of the leaf springs
lie on the box-like housing of the rear axle 6
and are retained in place by the bolts or pins 61
which are inserted through apertures provided 20
in plates 68 which are in turn secured at both
sides of the axle housing as shown particularly
in Figure 14.
Upon the underframe I in the vicinity of axle
6 to spaced bars 69 are provided which receive 25
the axle housing between them. The bars 69 are
preferably secured by welding to the underframe
I and are in turn supported. by the two reinforcing
plates ‘I6 welded between the bars and the yoke 8.
Welded at both sides of the axle housing 6 are 30
two guide members ‘II which are bent convexly
relative to the guide bars 69. In this manner
there is formed an upwardly and downwardly ex
panding guide passage for the bars 59 so that the
bars 69 in addition to the vertical movement per 35
mitted can also have simultaneously a slight oscil—
lation in a plane perpendicular to and parallel
with the axle 6.
In addition, two struts ‘I2 are attached by any
desired means such as the screws ‘I3 to the rear 40
axle 6. Welded to the tube I are two spaced
bearing plates ‘I4 and ‘I5 between which the con
necting member ‘I6 is rotatably mounted by means
of a pivot pin 11. The ends of the strut ‘I2 are
secured to the connecting member ‘I6 by welding. 45
The bearing plates ‘I4 and ‘I5 are supported by
the supporting plates ‘I8 shown particularly in
Figure 13 which are welded on one hand to the
bearing plates ‘I4 and ‘I5 and on the other hand
50
to the underframe I.
In order that the threshing machine may rest
?rmly upon the chassis or frame during the
threshing Wood edges ‘I9 are driven in between
the wheels 3 and the arms of the supporting yoke 55
8. The wedges are shown in dotted lines in
Figure 11. In order to accomplish this purpose
bracket members 86 are welded to- the yoke 8.
In order when driving in wedges ‘I9 not to exert
unnecessary strain on the leaf spring ‘I, the ten 60
sion screws BI indicated by dotted lines in Figure
11 are ?rst placed between the axle 6 and the yoke
8. For this purpose the yoke is provided with
eyelets 82 and flaps 83 are provided upon the
plates 68 therebelow, said plates 83 being pro 65
vided with a perforation for an attaching screw.
