REVOLVING CUTTING DEVICE

2 Claims.
(Cl. 56-4315)
My invention relates generally to an attach
ment for a grain divide board for cutting off the
grain as it is pushed onto the platform of the
combine by the grain reel, so that the grain on
the platform is freed to go into the threshing
part of the combine, and an important object of
my invention is to provide a simple and efficient
arrangement of the character indicated whereby
the operation of the combine is greatly facili
0
tated and made more e?icient.
Another important object of my invention is to
provide an attachment of the character indi
cated which can be easily and inexpensively in
corporated in standard types of combines.
Other important objects of my invention will
15
be apparent from a reading of the following de
scription in connection with the drawings,
wherein for purposes of illustration I have
shown a preferred embodiment of my invention.
In the drawings:
20
Figure 1 is a general side elevational view
showing a combine reel in driving relation to the
rotary cutter of the present invention.
Figure 2 is a top plan view of Figure 1.
M Di
Figure 3 is a horizontal sectional View taken
through the rotary cutter and showing the hori
zontal cutting blade and guard in top plan.
Referring in detail to the drawings, the nu
meral 5 refers generally to the end portion of
the reel of the combine which is partly supported
by the declining bar 3 and has on its axle 1 the
sprocket wheel 3 over which is trained the
sprocket chain 9 which sprocket chain is trained
over a small sprocket wheel ID on an axle H
which has ?xed thereto the larger sprocket
wheel l2 over which is trained the sprocket
chain l3 which is also trained over the small
sprocket wheel I4 which is ?xed to the axle IE
on which is also the rotary cutter I6.
Pivotally connected to the axle I5 is the tight
ener and supporting bar ll’ and also the tighten
ing and supporting bar l8 on which is slidably
mounted the chain tightener sprocket 19 which
is adjustable in the slot 20. A bolt 2! in a slot 22
A) in the upper end of the bar 18 connects with the
bar 6. A bolt 23 in the slot 24 in the left hand
end of the bar ll adjustably connects the bar H
with the vertical frame member 25 which has a
bolt 26 which secures the bar 6 at the left hand
50 end thereof.
1
The idler sprocket I9 which is utilized as a
sprocket tightener, engages the underside of the
lower ?ight of the sprocket chain 9.
A tightener bar 2‘! carries the axle [5 at its
55 lower end and has a slot 28 in its upper end
which is slidable on the axle II and adjustably
secured by a wing nut 21’ threaded in the end
of the axle II.
The lower end of the frame member 25 is fas
tened in conjunction with the combine platform
39 and also attached to the vertical member 25
by the bolt 31 is the knife carrying bar 32 which
has on its laterally outward side the cutting
knife 33. Attached at the forward end of the
knife by bolts or rivets 3:2 traversing the bar 32 10
and having a laterally outwardly deflected por
tion 35 is the guard which is generally designated ,
36 and which extends along the laterally outer
side of the rotary cutter E6, the rotary cutter
having its peripheral edge extending between the 15
bar 32 with its cutter 33; and the guard 35.
The various bars described may be of strap
iron and due to their arrangement and combina~
tion can be adjusted to tighten the various
sprocket chains for ef?cient operation and to 20
take up wear.
As the grain is picked up and cut oif by the
cutter knife it is then pushed onto the platform
30 by the grain reel 5. In accordance with the
present invention, as the grain comes in contact 25
with the rotating cutting disk i6 and the cutting
blade 33 on the cross bar 32, the grain which
extends out over the end of the platform, will be
cut off, and the grain on the platform made free
to travel without impediment into the thresh 30
ing part of the machine. The cutter of the in
vention is used at the outer end of the platform
and positively prevents lodging of the grain on
the end of the platform.
The rotary cutter I6 is a disk with teeth 36 on 35
its periphery which are segmental in shape and
which in conjunction with the guard 35 and the
cutter 33 on the bar 32, positively shear and cut
the grain overhanging the end of the platform.
Although I have shown and described herein a 40
preferred embodiment of my invention, it is to
be de?nitely understood that I do not desire to
limit the application of the invention thereto,
and any change or changes may be made in the
materials, and in the structure and arrangement 45
of the parts, within the spirit of the invention
and the scope of the subjoined claims.
What is claimed is:—
1. In combination with a combine having a
platform and a reel, a knife at the outer end of 50
the platform, a guard in spaced parallelism with
the knife, and rotary cutter means adjustably
supported adjacent the outer end of the platform
and working between the knife and the guard in
shearing relation to said knife for cutting off
2
2,078,730
grain bridging the knife and the guard, and drive
means connecting the reel and the rotary cutter.
2. In combination with a‘ combine having a
platform and a reel, a horizontal knife at the
5 outer end of the platform, a guard in spaced
parallelism with the knife, and rotary,r cutter
means adjustably supported adjacent the outer
end of the platform and Working between the
knife and the guard in shearing relation to said
knife for cutting off grain bridging the knife and
the guard, and drive means connecting the, reel
and the rotary cutter, means supporting said
horizontal knife and a guard thereon extending
along the laterally outward side of the rotary
cutter.
