40nally and through the arm 27 the yoke 24
will be swung in the bearing 23 so that the
blades 26 may be forwardly or rearwardly
disposed as desired. The said blades are
adapted to move along the opposite sides of
a row of standing plants and clean the soil
at the sides of the row and cast the same
away from the row. By the adjustment
stated it is possible to cause the blades to
operate at any desired distance below the
surface of the soil, although the blades may
be so positioned that they will be entirely
above the surface of the soil.
The frame 1 is provided with bearings 36
in which a. shaft 37 is slidably journaled.
A beveled gear wheel 38 is fixed to the axle
4 and meshes with a. beveled pinion 39 fixed
to the rear end of the shaft 37. A coiled
spring 40 is interposed between the forward
bearing 36 and a shoulder 41 carried by the
shaft 37 and the said coiled spring is under
tension with a tendency to hold the shaft
37 in a rearward position so that the pinion
37 is normal y in mesh with the gear wheel
38. A lever 42 is fulcriumed upon the frame
I of the standard and its lower end lies
between collars fixed to the shaft 37.
Thus it will be seen that by swinging the
lever 42 the shaft 37 will move longitudi-
nally against the tension of the spring 40
whereby the beveled pinion 39 will be car-
ried out of mesh with the beveled gear
wheel 38.
A collar 44 is fixed to the intermediate por-
tion of the shaft 37 by means of set screws
45 and the said collar 44 is provided at its
opposite sides with collars 46 which are
disposed at right angles to the said collar
44. The collars 46 are provided with set
screws 47. Hoe shafts 48 pass through theCopies of this patent may be obtained for five cents each, by addressing the " Commissioner of Patents,
Washington, D. C."collars 46 and are secured in adjusted posi-
tion therein by means of the set screws 47.
Hoe blades 49 are carried at the outer end
of the hoe shaft 48.
Thus it will be seen that an especially de- 45
signed cotton chopper structure is provided
and means is provided for adjusting the
parts of the chopper to meet requirements
and to operate upon the crop to the best
advantage. 50
Having thus described the invention what
I claim as new and desire to secure by Let-
ters Patent is
A cotton chopper comprising an approxi-
mately rectangular frame having a forward 55
extension provided at its forward end with
a bearing, supporting wheels journaled for
rotation at the sides of the rear portion of
said frame, a bracket mounted upon said
extension and having a bearing at its upper 60
forward end, a standard journaled in the
bearings of the extension and bracket, an
axle fixed to the lower end of said standard,
ground wheels jouirnaled upon said axle, a.
lever adju stable fixed to the standard, a 65
spring pawl carried bly the lever, a toothed
segment fixed to the bracket and adapted to
be engaged by the pawl, a sleeve slidably
mounted upon said standard between the
bearing at the extension of the frame and 70
the bearing at the forward end of the
bracket, and a draft means connected with
said sleeve.
In testimony that I claim the foregoing
as my own, I have hereto affixed my signa- 75
ture in the presence of two witnesses.
PEET CARLSON.
