. WILLIAM LAFAYETTE EDDY, OF STAR, TEXAS.
CULTIVATOR.
SPECIFICATION forming part of Letters Patent No. 754,130, dated March 8, 1904.
Application filed September 29, 1903. Serial No. 175,074. (No model.)To all whom it may concern:
Be it known that I, WILLIAM LAFAYETTE
EDDY, a citizen of the United States,residing at
Star, in the county of Mills and State of Texas,
5 have invented new and useful Improvements in
Cultivators; and I do hereby declare the follow-
ing to be a full, clear, and exact description of
the invention, such as will enable others skilled
in the art to which it appertains to make and
10 use the same.
The invention relates to improvements in
cultivators, and has for its object to provide a
simple and comparatively inexpensive device
capable of ready adjustment to vary the dis-
15 tance between the cultivator-beams and shov-
els carried by the same, whereby the soil may
be thrown as close to the plant as desired,
thereby obviating the necessity of hoeing the
rows after a cultivator has passed along the
20 same.
With these and other objects in view the in-
vention consists in the construction and novel
arrangement of parts hereinafter described
and shown, and particularly pointed out in the
25 appended claim.
In the drawings forming part of this specifi-
cation, and in which likenumeralsof reference
designate corresponding parts, Figure 1 is a
plan view of a cultivator constructed in ac-
30 cordance with this invention. Fig. 2 is a
transverse sectional view. Fig. 3 is a detail
perspective view of the adjusting device.
Referring to the drawings, 1 designates the
cranked or arched axle of a cultivator, to which
35 axle is hinged a pair of laterally-movable hori-
zontally-swinging cultivator-beams 2 and 3,
which are provided with cultivator blades or
shovels 4 of any desired construction. The
cultivator-beams may be hinged to the crank
40 or arched axle at opposite sides of the crank
or arch at 5 by any suitable means, and they
are connected between their ends by an arched
bar 6, which is adapted to straddle a row and
which is suitably secured at its end 7 to the
45 cultivator-beam 3 by a clip or any other suit-
able fastening device. The other end, 8, of
the connecting-bar 6 is pivoted to an upper
horizontal arm 9 of a vertical crank-shaft 10,
which is journaled in a suitable bearing or
50 opening of a block 11. The block 11, whichis provided at its inner side with a recess to
fit the cultivator-beam is secured to the same
by a clip 12, and it performs a double function
of a bearing-block and a clip-plate. The lower
end of the crank-shaft is provided with an 55
inwardly-extending horizontal arm 13, which
is connected by a rod 14 with the lower end
of an upright lever 15. The upright operat-
ing-lever 15 is fulcrumed between its ends by a
bolt 16 or other suitable fastening device to 60
a toothed segment 17, which is provided at
its curved upper edge with teeth 18, adapted
to be engaged by a spring-actuated dog or
pawl 19, whereby the lever is secured in its
adjustment. The toothed segment 17 is pro- 65
vided at its bottom with a yoke which strad-
dles a beam and which is- secured to the same
by a bolt 21 or other suitable fastening means
whereby the segment is mounted on the beam.
The spring-actuated dog or pawl is guided in 70
a casing or housing 22, secured to the lever
at a point above the segment and provided at
the outer side thereof with a depending lip,
the segment being interposed between the lip
and the lever. A latch-lever 23 is fulcrumed 75
on the operating-lever at the top thereof and
is connected with the dog or.pawl by a rod
24 and is adapted to withdraw the pawl or
dog from engagement with the toothed seg-
ment to permit the operating-lever to oscil- 8o
late freely.
When the operating-lever is oscillated, the
upper arm of the crank-shaft is oscillated and
the cultivator-beams are swung horizontally
and move toward or from each other, accord- 85
ing to the direction in which the operating-le-
ver is moved, and by this construction the cul-
tivator-beams may be moved the desired dis-
tance apart. This will permit the operator
to throw the soil an exact distance and will 90
obviate the necessity of hoeing a row after
the cultivator has passed along the same.
What I claim is-
The combination with a cultivator having
laterally-movable cultivator-beams, of a bear- 95
ing-block provided at its inner face with a
recess to receive one of the beams, a clip se-
curing the bearing-block to said beam, a seg-
ment having a yoke straddling the beam on
which the bearing-block is mounted, a verti- 100ao. 754,1.30.
