Ira Burley, Redwing, Minn.--This invention consists in the combination
of wheels and axle, tongue, adjusting bar, adjustable brace, uprights,
cross bar, two ropes, and four pulley blocks with each other. To the
forward end of the tongue is attached a loop or clevis, to receive an
iron pin, to be driven into the ground to keep the machine from moving
about while being used. To the pulley block is swiveled a hook, to be
hooked into a loop, attached to the forward end of a lever. The rear
end of the lever passes through a slot in the upper end of a fulcrum
post, and has a notch formed in its lower side to receive a bolt or
pin, attached to said post to serve as a fulcrum to said lever.
Several notches are formed in the lever to receive the fulcrum bolt,
to enable the position of the fulcrum post to be adjusted to regulate
the leverage, and as circumstances may require. To the lever is
attached a strong clevis, to receive the hook of the chain, that is
secured to the stump to be pulled.
IMPROVED SEED PLANTER.
Daniel J. Davis, Red Boiling Springs, Tenn.--In this invention two
wheels revolve upon the journals of the axle. Upon the end parts of
the axle are attached the rear ends of side bars, the forward ends of
which are bolted to the outer sides of the forward ends of the plow
beams. The forward ends of the beams are bolted to the ends of the
front bar, to the center of which is secured the forward end of the
central bar. To the beams are attached the plows for opening furrows
to receive the seed as it passes from the conductor spouts. The lower
ends of the spouts or tubes pass in through the sides of the plows, so
as to conduct the seed into the bottom of the furrows before they have
been partially filled by the falling in of the soil. The dropping
plate is concaved around its dropping holes, and is provided with a
plate that may be adjusted to cover one set of dropping holes to drop
the hills twice as far apart as when both sets of holes operate.
