BRUNO SCHWAB, RICHARD SCHNEIDER, AND HAVER HOEGENAUER, OF SAN ANTONIO,
TEXAS.
COTTON-CHOPPER.1,3"7x,474.
Specification of Letters Patent.
Patented Apr. 12, 1921.
Application filed June 21, 1919. Serial No. 305,799.
To all whom it mayconcern:
Be it known that we, BRUNo SCHwAB,
RICHArD SCHNEIDER, and HAVER HOEGEN-
AUER, citizens of the United States, residing
5 at San Antonio, in the county of Bexar
and State of Texas, have invented a new
and useful Cotton-Chopper, of which the
following is a specification.
This invention relates to machines for
10 chopping and cultivating cotton, one of its
objects being to provide a simple and com-
pact machine which can be placed astride a
row and drawn therealong whereby a rotary
chopping element will be actuated to cut out
15 plants at regular intervals.
Another object is to provide means for
adjusting the chopping element during the
forward movement of the machine so that it
can be raised or lowered at will.
20 A further object is to provide means
under the constant control of the operator
for cultivating between the rows during the
chopping operation.
With the foregoing and other objects in
25 view which will appear as the description
proceeds, the invention consists of certain
novel details of construction and combina-
tions of parts which will be hereinafter
more fully described and pointed out in the
30 claim, it being understood that various
changes may be made in the construction
and arrangement of the parts without de-
.parting from the spirit or sacrificing any of
the advantages of the invention as set forth
35 in the appended claim.
In the accompanying drawings the pre-
ferred form of the invention has been
shown..
In said drawings-
40 Figure 1 is a plan view.
Fig. 2 is a side elevation, one of the sup-
porting wheels being removed and its axle
shown in section.
Fig. 3 is a section on line 3-3, Fig. 1.
45 Fig. 4 is a section on line 4-4, Fig. 1.
Referring to the figures by characters of
reference, 1 designates an axle carried by
supporting wheels 2 and on this axle is
mounted a housing 3 and a differential cas-
50 ing 4. A frame is mounted on the housing
3 and includes side members 5 the rear ends
of which are connected by an arch 6 while
the front portions are extended forwardly
and inwardly, as at 7 and are connected to
55 a draft beam 8 suitably braced, as at 9. An-other arch 10 is secured to and extends up-
wardly from the side .members and -has its
lower terminals connected to the front por-
tion of the frame by braces 11. A top beam
12 is secured upon the middle portions of 60
the arches and has its front end downturned,
as at 13 and secured to. the beam 8. A brace
14 may be extended forwardly from the
beam 12 to the beam 8.
Mounted on the housing 3 are split sleeves 65
15 each of which has oppositely extending
bosses 16 into which extend pivot screws 17
extending through attaching plates 18 se-
cured to the- front ends of beams 19. Thus
the beams are free to swing upwardly and 70
downwardly relative to the housing 3 and
also to swing laterally about the screws or
bolts 17. To the beams are attached sleeves
20 to which are clamped the standards of
cultivator blades 21, said standards being 75
indicated at 22. Ears 23 are extended up-
wardly from the sleeves 20 and are engaged
loosely by the offset lower ends 24 of a
spacing yoke 25. This yoke bridges the
space between the beams 19 and is supported 80
in an upstanding position by a link 26
which connects it. to the beam 12.
Secured to the arch 6 at each side thereof
is a toothed segment 27 and hand levers 28
are connected thereto and adapted to be held 85
thereby, the lower ends of these levers being
adjustly engaged by rods 29 which, in turn,
are attached to springs 30 secured to the
beams -19. By means of these levers the
beams can be raised or lowered to regulate 90
the depth of the blades 21 below the surface
of the soil.
Journaled in bearings 31 at the sides of
the frame is a controlling shaft 32 having a
forwardly extending crank 33 carrying a 95
loop 34. In this loop is loosely mounted a
sleeve 35 adapted to swing freely with the
differential housing or casing 4 and jour-
naled in the sleeve is a shaft having suit-
able gearing, not shown, whereby motion is 100
transmitted thereto from either of the
wheels 2 and their axles 1, said gearing being
of the usual differential type. This shaft
36 is secured at its forward end to a head 37
carrying oppositely extending arms 38 to 105
which hoes 39 are detachably connected. A
hand lever 40 is secured to and extends up-
wardly from the shaft 32 and by means
thereof the shaft can be rotated so that the
loop 34 will raise or lower the sleeve 35 and 110
