end of the rock-shaft U. The free end of the
bell-crank Y pivoted on the tongue has sus-
pended therefrom a hanger composed of a
member 5 slotted at its lower end and a bent
5 member 6 secured thereto to form a fork
which straddles the forward end of the plow-
beam as.shown, said member 6 being slotted
to correspond with the member 5. A bolt 7
passes through both members and the beam
1 C but remains loose in order that the beam may
play up and down between said members a
purpose which will be understood later.
From the foregoing it will be seen that a
movement of the lever toward the rear of the
15 machine will raise the beam as indicated in
Fig. 4 to any desired height. When the
limit of height is reached the beam will con-
tact with the rock-shaft as shown by broken
lines and if the lever is still further moved as
20 shown by said broken lines the forward end
of said beam will be raised since the point of
connection of the arms W and the beam is
above the point where the beam and shaft
U meet. The result is to tip or raise the ex-
25 tremity of the plow-member or point S still
farther from the ground so as to be entirely
free of all obstructions that may be passed
over during the time the implement is pass-
ing to or from the field. In referring to the
30 foregoing, the plow-beam is indicated by M,
the same being substantially of the form
usually employed on plows, the forward end
having a clevis N while a furrow-opener S
already mentioned is carried at the lower
35 end of the beam in any good manner. The
beam M has secured thereto an arm or drag-
bar 8 and a shovel 9 which are common to
most all machines of this character, these
being rigidly secured thereto. The said arm
40 8 also has attached thereto a shield 10
through which the seed drops from the seed-
tube 11 of the box L.
Hereinbefore we have described the ret
lation of the frames F, F, G and J to each
45 other and to the main frame A and we now
desire to describe the manner in which they
are operated to raise the seed tube and the
coverers or shovels H from the ground simul-
taneously with the raising of the plow-beam.
5o Secured to the rock-shaft U near each end
just inside the frame A is a member 12 de-
signed to contact with the under side of the
frame F, F, G to raise that member when
the lever 4 is operated to raise the beam NI,
55 this being shown in Fig. 6 in dotted lines.
Attached to the frame members FF are de-
pending L-shaped members 13 which when
raised with said members FF contact with
and raise the seed-box frame J as shown in
6o Fig. 4, said members, however, being free of
frame A while at work. By the peculiar
combination of elements entering into the
construction of the planter all the ground
engaging members are raised simultaneously.
65 ,3In hitching the horses to the beam M thatmember takes the entire strain and the
planter in the rear is drawn forward by rea-
son of the connection of the beam with the
rock-shaft U. The forward end of the beam
is permitted to "float" the bolt 7 being 70
loose so that it may play up and down in the
slotted members 5 and 6 as explained. By
this means all the downward pressure on the
tongue heretofore existing by reason of the
older constructions is eliminated and the 75
horses are not unnecessarily burdened.
As may be inferred it is one of our aims to
provide a stop against which the plow-beam
may strike when it has been raised to its up-
ward limit in order to elevate the point of the 8o
furrow-opener. This is accomplished by caus-
ing the beam to contact with the rock shaft
U as already described but we desire to make
it plain that we may provide a special stop
at some other point if found desirable, using 85
it in lieu of the said shaft. It is not the in-
tention to confine ourselves to the particular
means shown and described as to any part or
combination of parts in our improved cotton
and corn planter since equivalent mechanism 90
may be employed.
What we claim is
1. The combination with a main, wheel-
supported planter frame having a guiding
tongue, of a plow supported by said frame 95
and swinging freely upon a horizontal pivotal
axis and arranged to transmit the entire trac-
tional force of the horses, a covering shovel
frame pivoted to said main frame, a seed-box
frame pivoted to the shovel frame, and a sin- oo
gle means for at will raising the plow, bodily,
the shovels and the seed-box out of operative
positions.
2. The combination with a main, wheel-
supported planter frame provided with a 105
rigidly attached guiding tongue, of a plow
support pivoted to said frame, a plow having
its beam pivoted to said support and swing-
ing freely in a vertical plane upon its pivot, a '
rearwardly extending shovel frame pivoted i o
to the main frame, a seed-box frame pivoted
to the shovel frame, and a single means for
at will swinging upward the plow, bodily, the
shovel frame, and the seed-box frame, sub-
stantially asset forth. .15
3. The combination with a main, wheel-
supported, plow-carrying frame having a
rigidly attached guiding tongue, an arm piv-
oted to the main frame to swing on a hori-
zontal pivot, a plow beam pivoted to the free 120
end of said arm and rocking freely in a ver-
tical plane upon its pivot, draft devices at-
tached to the forward end of the plow beam, a
stop in the rear of the beam pivot to arrest
the upward movement of the rear end of the 125
beam at a predetermined point when it is
lifted by said arm, a shovel frame pivoted to
the main frame and extending to the rear of
the axle, a seed-box frame pivoted to the
shovel frame, and a single means for swinging 1302
