J. T. D. ALEXANDER, OF MARIANNA, TEXAS.
IMPROVEMENT IN CULTIVATORS.
Specification forming part of Letters Patent No. 31,101, dated January 15, 1861.To all whom it may concern:
Be it known that I, J. T. D. ALEXANDER, of
Marianna, in the county of Polk and State of
Texas, have invented certain new and use-
ful Improvements in Cultivators; and I do
hereby declare that the following is a full, clear,
- and exact description of the same, reference
being had to the accompanying drawings, and
to the letters of reference marked thereon.
The nature of my invention consists in con-
structing and arranging the several parts of
this machine in the manner hereinafter set
forth.
In the annexed drawings, Figure lis a plan
view. Fig. 2 is a side elevation. Fig. 3 is an
end view.
In the figures, A A represent two beams or
straight bars, which are connected together
by means of the curved bars BB B. The bars
B are made in the form shown in the draw-
ings, being curved at their centers, so as to
pass over cotton-plants or other growth, and
being straight at their ends, so as to pass
through mortises in the beams A A.
The straight portions of the bars B B are
provided with mortises or long openings, in
which wedges are inserted on one or both sides
of the beams A for the purpose of regulating
and adjusting the width between said beams.
H H represent angular side bars, which are
provided with straight ends, in which are open-
ings through which the ends of the bars B B
pass in order to firmly secure said bars to the
sides of the beams A. The shanks to which
the plow-blades are attached are secured to
the bars H H at the front of the plow-frame;
but the shanks to which the rear blades are
attached are secured directly to the beams A,
as is seen in the figures.
The beams are supported upon wheels D D,
and connected to said wheels by means of
crank-axlesE E. The arm of the crank which
is secured to the beam is provided with a long
slot through which a bolt passes. The object
of this slot is to allow the beams to be raisedor lowered with respect to the ground. The
bolt which secures the arm to the axle may be
loosened and the frame then lowered or raised,
after which the beam will be stationed at the
desired point by tightening up a nut upon the
bolt.
O represents the handles of the cultivator.
These handles have their front support in the
center bar B, and their rear support by means
of standards in the rear bar B.
The plow-blades are secured to the shanks
by being caught under a shoulderat their up-
per ends, said shoulder being upon the shanks,
and then further secured by means of a bolt
which passes through the blade and through
the shank. By this arrangement of parts it
will be seen that the frame may be readily ad-
justed to or from the ground, and that the
plow-blades may be brought close together or
separated at pleasure.
The bars H H may be brought on the inside
of the beams when said beams are separated
farther apart, or they may be allowed to re-
main on the outside.
A great variety of blades may be used and
substituted, the one for the other, upon this
frame, so as to adapt the cultivator to a va-
riety of uses.
It will be readily seen that a number of dif-
ferent combinations may be made with the
several blades for adapting the machine to any
required cultivation.
Having thus fully described my invention,
what I claim as new, and desire to secure by
Letters Patent, is-
The arrangement of the beams A A, the bars
B B and H H, as constructed, the shanks F F,
the wheels D D, and the slotted crank-axles
E E, the whole being arranged and connected
in the manner and for the purpose herein speci-
fied.
