Improvements in Seeding Machines.
A communication from JAMES NOXON, of the Town of Woodstock, in the County
of Oxford, Province of Ontario, Canada, Manufacturer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :—
The object of the invention is to improve and simplify the construction of that
portion of a seeding machine connected with the angling and zig-zagging of the hoes
or teeth; and it consists in the arrangement and construction of parts as hereinafter
more particularly explained.
Figure 1 is a perspective view of that portion of a seeding-machine to which this
invention relates.
Figure 2 is a perspective view of the lever and its connections by which the zig-
zagging of the hoes or teeth is effected.
Figure 3 is a perspective detail of the lever and its connection by which the
angling of the hoes or teeth is effected.
In the drawing A represents a stationary frame on which the seeding-box B is
fixed and the main axle C is supported.
D is a light metal frame preferably made of steel and pivotted at a on the
frame A.
E is a tongue secured by the bracket F to the axle C and to the seeding-box B
by the bracket G.
The diagonal braces H extend from the axle C to the tongue as indicated.
I is a rock-shaft suitably journalled in the boxes J which are supported respectively
by the diagonal braces H and tongue E as indicated. On each end of the rock-
shaft I, I fix the arms K which are connected by the links L to the frame B as
shown.
M is a T-crank journalled on the rock-shaft I and connected at one end to the
frame D by the link N and at its other end to a rod O which at its other end is
connected to the horn P pivotted at 6 on the quadrant bracket Q which is fixed to
or forms part of the bracket F connected to the tongue E as indicated in Fig. 3.
The lever S fixed to the horn P extends behind the seeding-box B to a point
convenient to the man walking behind the machine.
A lever T which like the lever S extends behind the seeding-box B is fixed to a
horn U which is pivotted at d to the stationary quadrant V. The horn U is con-
nected by the link W to the lever X which is fixed to the shaft Y suitably journalled
in the frame A as indicated. A series of short arms Z are fixed to the shaft Y and
project alternately above and below the said shaft. Each arm Z is connected by a
bar 4 to a loop 5 pivotted on the rod 6 which is suitably supported by the frame D.
Each pair of drag-bars 8 is connected to an independent loop 5.
Owing to the connection between the lever T and the shaft Y as already described
the movement of the lever T causes the said shaft Y to roll in its journals and
owing to the connection between the short arm Z and the loops 5 the rolling of the
shaft Y throws one set of the loops 5 forward and simultaneously draws the other
set of loops backwards, and as each pair of drag-bars 8 and the hoes connected to
them are thus zig-zagged one set being thrown forward while the other set is
simultaneously thrown backward, and as all the loops 5 are the same length and move
the same distance all the hoes or teeth are set at the same angle. The fact that
all the hoes or teeth correspond with each other in the angle at which they are set

page_text: is a very important feature in this invention as the connection of all the teeth or
hoes on the ground will correspond.
Each pair of drag-bars 8 is connected by the chain 7 to the roll 9 journalled in
the front of the frame A. as indicated in Fig. 1. The roller 9 is provided with a
lever 10 by the movement of which the roller 9 is caused to revolve and thus raise
the teeth or hoes as required.
Owing to the connection already described between the lever S and the rock-
shaft I the movement of the said fever causes the rock-shaft I to roll in its journals
and as this rock-shaft I is connected as already described to the frame D the move-
ment of the lever S raises or lowers the frame D according to the direction in which
the said lever S is moved.
Having now particularly described and ascertained the nature of this said
invention as communicated to me by my foreign correspondent and in what
manner the same is to be performed I declare that what I claim is :-
I. The pivotted frame D to which the drag-bars 8 are connected in combination
with the rock-shaft I connected to the frame D and operated by the lever S sub-
stantially as and for the purpose specified.
II. The tongue E braced by the diagonal braces H the journal boxes J for the
rock-shaft I the arms K and links L connecting the rock-shaft I to the frame D in
combination with the T-crank M fixed to the rock-shaft I and connected to the
lever S by the rod O and horn P substantially as and for the purpose specified.
III. A series of pivotted loops 5 projecting below the frame D each loop
supporting an independent drag-bar in combination with mechanism arranged to
rock the said loops in such a manner as to zig-zag the hoes or teeth connected to
the drag-bars substantially as and for the purpose specified.
IV. A series of independently pivotted loops 5 each loop having a pair of drag-
bars & attached to it and each loop independently connected by a bar 4 to a short
arm Z on the shaft Y the said arms projecting alternately from opposite sides of
the said shaft in combination with the lever T arranged to roll the shaft Y sub-
stantially as and for the purpose specified.
