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 simplify and improve that portion of the
machine (which is of the type generally known as spring-hoe-grain drills) con-
nected with the drag-bar and operating mechanism; and it consists in the
arrangement of parts hereinafter more particularly explained.
Figure 1 is a perspective view of one half of the machine in which these
improvements are involved the axle-supporting wheel corresponding to this half
being omitted from the drawing for the sake of clearness.
A is the main frame of the machine, made of channel iron or steel and connected
to the axle B by the bracket C. D is a rod journalled in suitable brackets E
fastened to the frame A as indicated. Arms F are rigidly fastened to the rod D
and pivotally connected to the lifting links G which are connected to and support
the rod H to which the drag-bars I are connected. The connections between the
drag-bars I and the rod H are made by clips J rigidly fastened to the rod H
and extending beyond the rod in such a manner that the drag-bars may be
connected in pairs alternately on either side of the said rod H so that the rolling
of the said rod will, what is termed, "zig-zag" the drag-bars and the hoes or teeth
connected thereto. Each end of the rod H is connected to a bracket C (one of
which is located on each side of the machine) by a bar K.
A lever L preferably pivotted on the axle B extends behind the seed-box M and
is connected as indicated to the bell-crank NF which is fixed to the rod D and one
of its arms F is connected to one of the lifting links G thereby connecting it to the
rod H as shown. A suitable toothed quadrant is arranged in connection with the
lever L so that when the lever is turned on its pivot it may be held in any desired
position. By this lever the rod H may be raised or lowered as required from the
rear of the machine. A similar lever O extends behind the seed-box M and is
likewise pivotted on the axle B. A crank P is formed on this lever and is con-
nected by the rod Q to one of the clips J and through this connection the
movement of the lever O will roll the rod H and thus zig-zag the hoes as required;
the whole operation being effected from the rear of the machine. A bracket R is
attached to the bottom of the tongue S and has a longitudinal opening in it,
through which the rod H passes. In order to prevent the longitudinal movement
of the said rod H I place one of the clips J on either side of the bracket R so that
they will butt against the said bracket and prevent the longitudinal movement
mentioned.
It will be noticed that the heel a of the hoe T extends down on a level with the
point b of the said hoe. This shape of hoe is important when used in connection
with a machine constructed in accordance with this invention as it will prevent the
hoe from entering too far into the soil.
The seed is conveyed from the seed box M to the drill hoes by suitable
conductors into which it is fed by a suitable feeding device.

page_text: 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 :-
1. The rod H suspended by the links G from the arms F which are attached to
the rod D the bars K connecting the rod H to the bracket E in combination with
the lever L extending behind the seed-box M and connected to the rod H
substantially as and for the purpose specified.
2. The rod H suspended by the links G and having a series of clips J connected
to it and arranged so that the drag-bars I may be connected in pairs on either side
of the rod H in combination with the crank-lever O extending behind the seed-
box M and connected by the rod Q to one of the clips J substantially as and for
the purpose specified.
3. The rod H passing through the bracket R and having clips J fixed to it on
each side of the said bracket, substantially as and for the purpose specified.
4. A hoe T having a heel a substantially on a line with its point 6 in combination
with drag-bars I connected to the clips J fixed to the vertically-adjustable rod H
substantially as and for the purpose specified.
Dated this 16th day of March 1891.
