shank-holder 1S and casting 1l( consists of anll
eyebolt 22, in which the shank 23 of the cul-
tivator device is securely held by means of a
nut 24 on said bolt. The eyebolt 22 is adapt-
5 ed to turn with the shank-holder 18, and it
will thus be seen that by withdrawing the pin
21 the cultivator device, whether a plow,
sweep, or scraper, can be turned to any de-
sired angle and be again secured in the de-
ro sired position. To each shank 23 may be se-
cured a scraper 25 or a heel sweep or scooter
or shim-plow 27, or other device, as preferred.
When the plows 25 are used, the clamping-
bars 17 are preferably made of sufficient length
15 to extend inward to thebeam 1,and these ex-
tended bars are curved forward and formed
with a twist, as shown, so as to rest on top of
the beam against which they are thus adapt-
ed to bear and serve as braces for the plows
20 to counteract any tendency of the plows pull-
ing back under the draft of the machine and
the resistance thereto consequent on the em-
ployment of broad plow-blades.
The horizontal arms of the castings 16 may
25 be of varying length, so as to cause the culti-
vator devices to project at varying distances
beyond the frame 10, as desired.
I may also attach to the harrow-frame 10 a
number of vertically-adjustable cultivator de-
30 vices 28, composed of the vertically-depend-
ing bars 29, provided with clamps 30, by which
they are adjustably secured in place, and the
vertically-adjustable shanks 31, attached to
the depending bars 29 by means of bolts or
35 rivets 32, passed through perforations 33 in
the blade shank and bar, each of which is
provided with a series of such perforations,
so as to permit the desired vertical adjust-
ment of the cultivator-blade. The adjustable
40 shanks 31 on the bars 20 also fulfill the con-
ditions required to regulate the depth of plow-
ing when the harrow-teeth 14 are removed.
It will be seen that by arranging and con-
necting the parts in the manner described
45 and providing a variety of interchangeable
cultivating devices the cultivator-harrow can
be used to advantage for various agricultural
purposes with great readiness and conven-
ience.
50 What I claim as my invention is-
1. A cultivator-harrow consisting of a cen-tral longitudinal beam 1, the loops 6, adjust-
ably supported on said beam, the pivoted lat-
erally-expansible frame 10, engaged with the
loops, the cultivator teeth or plows, and clamps 55
attaching the teeth or plows to the expansi-
ble frame and comprising horizontal clamp-
ing-arms extending forward between the sides
of such expansible frame and overlying and
engaging the central longitudinal beam, sub- 60o
stantially as described.
2. A cultivator-harrow consisting of a cen-
tral longitudinal beam 1, the loops 6, adjust-
ably supported on the beam, the pivoted lat-
erally-expansible frame 10, engaged with the 65
loops, and the interchangeable cultivator
plows or teeth having supporting-arms 16, en-
gaging the expansible frame, and clamping-
bars 17, which clamp said supporting-arms to
the expansible frame and extend forward be- 70
tween the sides of the latter and overlie and
engage the central longitudinal beam, sub-
stantially as described.
3. A cultivator-harrow consisting of a cen-
tral longitudinal beam 1, the loops 6, adjust- 75
ably supported on said beam, the pivoted
frame 10, engaged with said loops, the elbow-
castings 16, having clamping-bars 17, the piv-
oted shank-holders 18, having eyebolts 22, and
the cultivator-shanks 23, held in said eyebolts 80
and adjustable with the shank-holders, sub-
stantially as described.
4. A cultivator-harrow consisting of a cen-
tral longitudinal beam I, the loops 6, adjust-
ably supported on said beam, the pivoted ad- 85
justable frame 10, engaged with said loops,
the elbow-castings 16, having clamping-bars
17, extended inward and adapted to bear
against the beam 1, the pivoted shank-hold-
ers 18, having eyebolts 22, the cultivator- 9c
shanks 23, held in said eyebolts and adjust-
able with the shank-holders, and the cultiva-
tors 25, attached to said shanks, substantially
as described.
In testimony whereof I have hereunto set 95
my hand and affixed my seal in presence of
two subscribing witnesses.
