PROVISIONAL SPECIFICATION.
Improvements in Steering Gear for Grain and Seed Drills.
We, JAMES HORNSBY, and JOHN INNOCENT, both of Spittlegate Iron Works,
Grantham, in the County of Lincoln, Engineers, do hereby declare the nature of
this invention to be as follows:
This invention has for its object improvements in steering gear for grain and
seed drills.
At the front of the drill centrally, and in advance of the road wheels on which
the drill is mounted we place a guide wheel and this is carried in a frame or fork.
The frame or fork to which this guide wheel is attached has a vertical stemn
which is received into a bracket fixed to the drill frame and is free to turn
therein.
To the upper part of the guide wheel frame above the bracket a head is fixed
and to the head a guide lever is connected by a swivel joint.
The bracket also has a Hange upon it in rear of the swivel joint and the flange
has notches in it into which the guide lever drops so that when the lever is in one
of the notches the wheel can be moved by means of it.
The guide lever projects over the top of the machine and may be moved to
either side of the drill to a convenient position for the attendant walking directly
behind the road wheel from this position to steer the drill.
Two steering wheels may if desired be used.

COMPLETE SPECIFICATION.
Improvements in Steering Gear for Grain and Seed Drills.
We, JAMES HORNSBY, and JOHN INNOCENT, both of Spittlegate Iron Works,
Grantham, in the County of Lincoln, Engineers, 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 :-
This invention has for its object improvements in steering gear for grain and
seed drills.
Our improvements are shown in the annexed drawings of which
Figure is a side elevation partly in section and Figure 2 is a plan of
the drill.
At the front of the drill centrally, and in advance of the road wheels A A on
which the drill is mounted we place a guide wheel B and this is carried in a frame
or fork C. The frame or fork C to which this guide wheel B is attached has a
vertical stem D which is received into a bracket E fixed to the drill frame F and
is free to turn therein.
To the upper part of the guide wheel frame above the bracket E a head G is
fixed and to the head G a guide lever H is connected by a swivel joint I.
The bracket E also has a flange K upon it in rear of the swivel joint I and the
flange Khas notches in it into which the guide lever H drops so that when the
lever H is in one of the notches the wheel B can be moved by means of it.
Adjustable pieces L L' are fixed to the flange K.
The guide lever H projects over the top of the machine and may be moved to
either side of the drill as shown in full and dotted lines respectively to a convenient

page_text: position for the attendant walking directly behind the road wheel from this position
to steer the drill.
Two steering wheels may if desired be used.
In place of a single wheel B we sometimes use two wheels M M as shown in
Figure 3. If desired the wheels M M may be made so that the wheels A A'
follow in their track..
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
1. In grain and seed drills an adjustable steering lever which can be retained at
either side of the drill substantially as described.
2. A steering lever for grain and seed drills connected by a swivel joint
and notches to a head fixed to the frame of the guide wheel substantially as
described.
3. The steering gear substantially as described and shown in the drawings.
