HENRY A. MAYER, OF YORKTOWN, TEXAS, ASSIGNOR OF ONE-HALF TO BEN H.
JANSSEN, OF YORKTOWN, TEXAS.
CULTIVATOR.Specification of Letters Patent.
Patented Jan. 3, 1922.
Application filed November 29, 1919. Serial No. 341,424.
To acl wh oa it may concern:
Be it known that i, HENRY A. MAYER, a
citizen of the United States, residing at
Yorktown, in the county of De Witt and
5 State of Texas, have invented a new and
useful Cultivator, of which the following is
a specification.
This invention relates to cultivators, and
especially to riding cultivators in which
10 provision is made for turning the wheels to
guide the machine.
The primary object of the invention is to
provide a new and superior type of culti-
vator which when the wheels are guided by
15 the rider pressing down upon suitable foot
pedals or stirrups, the shovel gangs are
shifted in the direction toward which the
wb)eels are inclined, the gangs being main-
tained at all times in positions parallel with
20 the line of draft, or with the longitudinal
axis of the machine.
A further object is to provide a means for
resiliently holding the shovel gangs into the
soil, so that the depth of cultivation may
25 be as uniform as possible when operating
on uneven groin, or ihen working in dif-
we ent kinds of soil.
A further object is to provide a mecha-
nism for raising and lowering the shovel
30 gangs so that the gangs are always horizon-
tal in any adjusted position, this mecha-
nism cooperating with the means for resili-
ently holding the shovel gangs, so that when
any shovel strikes an obstruction, the gangs
35 will rise against the resistance of the said
resilient means and will slide or pass over
the obstruction, whatever their adjusted po-
sition may be.
Another object is to provide a readily op-
40 crated means for adjusting the distance be-
tween two shovel gangs, while maintain-
g each gang in its usual horizontal posi-
tion, parallel to the other.
1n additional object is to provide clamp-
45 ing means on the gang beams, whereby the
shovels mayb e adjusted at any height, on.
either side, and at any longitudinal posi-
tion with respect to the beams.
The preferred means by which I have ac-
50 comnplished the several objects stated are
illustrated in the accompanying drawingsand are hereinafter specifically described;
but I wish it understood that changes in the
form, size, material, proportion and minor
details of construction, may be made within 55
the scope of the appended claims.
In the drawings--
Figure 1 is a side elevation of a two-row
cultivator embodying. the improvements
which form the invention, showing it in 60
working position;
Figure 2 is a top plan view of the ma-
chine, showing the wheels in a guided posi-
tion;
Figure 3 is a longitudinal sectional view, 65
the line of section being substantially that
of 3-3 in Figure 2, the machine being'shown
with the gang beams raised, and the wheel
unauided;
jA igure 4 is a transverse sectional view, 70
taken on the line 4-4 of Figure 2, and look-
ing in the direction indicated, but showing
the wheels in their straight ahead position;
Figure 5 is a perspective detail view of
the means for adjustably attaching the rear 75
shovel standard to the gang beam and for
permitting the shovel to give when an un-
yielding obstruction is encountered;
Figure 6 is a section on the line 6-6 of
Figure 5, looking downwardly, and omitting 80
distant parts;
Figure 7 is a section on the line 7-7 of
Figure 5, looking in the indicated direc-
tion;
Figure 8 is a detail in plan of a part of the 85
mechanism which shifts the shovel gangs
toward or from each other, looking from
above;
Figure 9 is a detail in plan, looking from
underneath the machine, of the gang mecha- 90
nismt;
Figure 10 is a longitudinal section on the
line 10-10 of Figure 8;
Figure 11 is a detail in elevation looking
from the rear of the machine showing a 95
part of the same mechanism;
Figure 12 is a perspective view of one of
the shovel gangs removed from the ma-
chine;
Figure 13 is a transverse section taken 100
through the clamp which holds the second,
or intermediate plow standard to the beam;1,402,242.
