MORGAN C. TEDDER, OF SIMMS, TEXAS.
COTTON-CHOPPER.Specification of Letters Patent.
Patented Jan. 9,1912.
Application filed June 19, 1911. Serial No. 633,972.
Te all whom it may concern:
Be it known that I, MoRGAN C. TEDDER, a
citizen of the United States, residing at
Simms, in the county of Bowie and State of
5 Texas, have invented certain new and useful
Improvements in Cotton-Choppers, of which
the following is a specification, reference
being had to the accompanying drawings.
My invention relates to new and useful
10 improvements in cotton choppers and more
particularly to an attachment for a hand
guided chopper, and my object is to pro-
vide means for gaging the distance between
the frame of the cultivator and the ground
15 so that the chopping device will engage the
soil when the device is driven over all kinds
of ground.
A further object resides in providing a
chopping wheel having pivoted arms, and a
20 still further object resides in providing re-
silient means for action upon said arms,
whereby the hoes at the ends of said arms
are driven with considerable force into the
ground.
25 With these and other objects in view, my
invention consists in the novel features of
construction, combination and arrangement
of parts as will be hereinafter referred to
and more particularly pointed out in the
30 specification and claims.
In the accompanying drawing forming a
part of this application, Figure 1 is a side
elevation of the device. Fig. 2 is a top plan
view of the device, and, Fig. 3 is a side ele-
35 vation of the chopping wheel with one of the
side walls thereof removed.
In carrying out my invention, I shall
refer to the drawing in which similar refer-
ence characters designate corresponding
40 parts throughout the several views and in
which 1 indicates a frame of rectangular or
any other desired shape, oscillatingly
mounted on an axle 2, said axle having
mounted at the ends thereof, the driving
45 wheels 3. Permanently keyed on the axle
2 is an enlarged bevel gear 4 which meshes
with a similar but smaller gear 5 carried on
one end of a shaft 6, which is mounted on
said frame 1 and extends at substantially
50 right angles to the axle 2. This shaft 6 is
rotatably mounted in bearings 7 on cross
bars of the frame and has mounted on the
outer end, or end opposite that carrying the
gear 5, a rotary chopping wheel comprising
55 an elongated hub or the like 8, which hubconsists of a core 9 and the side walls 10.
Said side walls extend above and below the
upper and lower faces of said core, and said
upper and lower faces are, at opposite ends
thereof, slightly inclined, as disclosed at 11, 60
and pivotally mounted between the side
walls 10 at the ends thereof, is a pair of
arms 12, said arms being pivoted intermedi-
ate of their ends. One end of each of said
arms 12 is provided with a socket which is 65
adapted to receive the shank of a hoe 13,
the set screw 14 being provided to retain
said hoe in any adjusted position, and the
ends of said arms carrying these hoes are
disposed in opposite directions, as disclosed 70
in Fig. 3, so that as said hub rotates, the
engagement of the hoes with the ground will
be identical in each case.
Each of the arms 12 is provided adjacent
its pivotal point with a shoulder 15 which, 75
when the arms are properly positioned on
the hub, are disposed adjacent the inclined
portions 11 of the upper and lower faces of
said core, and secured between the side walls
10 of said hub and resting on said upper 80
and lower faces of the core, are the leaf
springs 16, the free ends of which are en-
gaged with the shoulders 15 of said arms.
The tendency of these springs 16 is to re-
tain the arms 12 in a substantially vertical 85
position, as disclosed in Fig. 3, so that the
same engage the ends of the core 9 and those
portions of said arms which are disposed be-
tween the pivotal points and the ends oppo-
site those carrying the hoes, are of greater 90
length than the portions between the pivotal
points and the hoe-carrying ends, the pur-
pose of which will be hereinafter and more
particularly described. Also carried on the
rear end of the frame 1 and in the path of 95
the free ends of the arms 12, is a roller or
the like 17 which, as the hub is rotated, is
adapted to contact with said free ends of
the arms and swing the same on their pivots
against the action of the springs 16. The 100
inclined portions 11 on the upper and lower
faces of said core 9 will allow the free ends
of the springs to be forced thereagainst by
the moving of the arms on their pivotal
points and as soon as the free ends of said 105
arms leave the roller 17, the springs 16 will
again force said arms into the position
shown in Fig. 3, but the hoes 13 will engage
the ground before said arms reach their ver-
tical positions, whereby it will be seen that 1101,013,969.
