Austin S. McDermott, Prairie Creek (Melleray P. O.), Iowa.--The object
of this invention is to furnish a cultivator which shall be readily
adjusted as the character of the work to be done may require, and
easily guided and controlled. The tongue of the machine is made in
V shape, and its rear end is attached to the axle. The arms of the
tongue are connected by a crossbar, to which the doubletree is pivoted
by a hammer bolt. To the ends of the axle are attached, or upon them
are formed, crank axle arms, upon the journals of which the wheels
revolve. To the arms of the tongue, near the forward end of said
tongue, are bolted the ends of the forward arms of the three-armed
bar, the third arm of which projects to the rearward, and its rear end
is bent into U form to receive a curved bar, which is pivoted to
the three-armed bar by a bolt that passes through the bend of the
three-armed bar and through the center of the curved bar. The ends of
the curved bar are secured to the forward ends of the beams by bolts,
two to each end. To the rear ends of the beams are attached handles
which may be strengthened by braces, and are designed for use in
guiding the plows when the machine is used as a walking cultivator.
