Improvements in Seed Drills, Horse Hoes, and like Agricultural
Implements.
I, THOMAS EAGLE MARTIN, of Barmer, near King's Lynn, in the County of
Norfolk, Farmer and Machinist, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in seed drills horse hoes and like
agricultural implements.
In such agricultural implements as heretofore usually constructed the seed
drills, hoes, etc., have required a separate attendant for steering which has been
effected by hand. Now, my invention has for its object to dispense with the
necessity of employing this special attendant and to this end I arrange for
steering the drills, hoes, etc., through the medium of the feet, the steering
apparatus being so constructed that it can be operated by the driver of the imple-
ment.
In carrying out my invention I advantageously provide a rocking shaft rotat-
ably mounted in the frame of the implement and carrying at its rear end a pair
of pedals, the said shaft and pedals being so placed that the driver of the imple-
ment, when seated in position, can support his feet upon, the pedals.. The rocking
shaft is provided with a crank secured to the drill or hoe frame in such a manner
that when the driver bears upon either pedal he oscillates the rocking shaft
thereby imparting the required movement to the drills or hoes.

.
I, THOMAS EAGLE MARTIN, of Barmer, near King's Lynn, in the County of
Norfolk, Farmer and Machinist, 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 relates to improvements in seed drills horse hoes and like
agricultural implements.
Such agricultural implements as heretofore usually constructed have generally
been steeered by a special attendant who has followed the implement on foot.

page_text: Now, my invention has for its object to dispense with the necessity of employing
this special attendant and to this end I arrange for steering the drills, hoes or
the like through the medium of the feet, the steering apparatus being so con-
structed that it can be operated by the driver of the implement riding on a seat.
In carrying out my invention I advantageously provide a rocking shaft rotat-
ably mounted in the frame of the implement and carrying at its rear end a pair
of pedals, the said shaft and pedals being so placed that the driver of the imple-
ment, when seated in position, can support his feet upon the pedals. The rocking
shaft is provided with either a crank or eccentric secured to the drill or hoe frame
in such a manner that when the driver bears upon either pedal he oscillates the
rocking shaft thereby imparting the required' movement to the drills or hoes.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, which illustrate the application of my
invention to a manure or seed drill.
Figure 1 being a plan view of such a seed drill with my improvements upon it.
Figure 2 a sectional side elevation of the same; and
Figure 3 a partial front elevation.
a is the framing of the drill which is mounted upon travelling wheels b. b and
adapted upon the front bar c for the attachment of shafts or other draught
apparatus.
d is the seed box and e, e are the coulters into which the seed is delivered from
the seed box through the usual sectional tubes. These coulters are carried by
levers f, which at their front ends are pivoted upon a bar g or auxiliary frame
and at their rear ends are supported by.chains h, h connected to a shaft i which
can be more or less rotated by a hand wheel 2¹ and held in position to regulate
the position of the levers f, f and consequently also the depth at which the
coulters e, e work, in a manner which will be readily understood. Instead of
the apparatus described I may employ a lifting lever with eccentrics to raise
and lower the coulters with a chain and bar.
The bar to which the coulter levers are pivoted is adapted to be moved
laterally relatively with the wheels and for this purpose it is suspended from
the frame a by links k, k.
Z is the rocking shaft through the medium of which the lateral movement is
imparted to the bar g. This rocking shaft is carried in the hangers or brackets m,
m depending from the frame a and is at one end provided with an arm or lever n,
the free end of which is connected by links o to the link k, whilst at its other end
it carries a double armed pedal p upon which the driver of the implement, when
seated upon a seat q, can place his feet in such a position that he can, by
depressing one or the other arm of the said pedal, rock the shaft m and so trans-
mit the desired lateral movement to the bar g or auxiliary frame.
In the drawings I have represented the implement as being provided with
two seats q, q and two pedal levers p, p, the said pedal levers being connected with
the links k, at the opposite ends of the bar g, so as to permit the steering to be
effected from either side of the implement.
In order te stop sowing I may employ an arrangement of apparatus for
striking or disengaging the gear wheel on the spindle of the seed box from
its driving wheel from either seat.
Although I have described my invention as applied to a seed or manure drill
it will be obvious that my improvements are equally applicable to a horse hoe
or other implement wherein the hoes or the like are carried by an independent
frame which is suspended from a main frame so as to be laterally movable
relatively therewith.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare, that what
I claim is:
1. In a seed or manure drill, horse hoe or like agricultural implement, the

page_text: combination with a main frame of a swinging frame supported by arms or chains
depending from the said main frame and carrying the coulters, hoes or the like
and a pedal arranged in proximity to a driver's seat and connected by suitable-
means with the said swinging frame in such a manner the the movement of the
said pedal serves to communicate lateral movement to the said swinging frame
relatively with the main frame, substantially as, and for the purpose, described.
2. In a seed or manure drill, horse hoe or the like, the combination of a main
frame, an auxiliary frame carried by arms or chains depending from a main
frame, a rock shaft pivoted in hangers depending from the said main frame,
means for connecting one end of the said rock shaft to the swinging
frame and a pedal upon the other end of the said rock shaft, all substantially as,
and for the purpose, described.
3. The improved means herein before described for steering the coulters or
tines of a seed or manure drill, horse hoe or the like by means of the feet of
a person riding upon such seed drill or horse shoe, substantially as hereinbefore
described and illustrated in the accompanying drawings.
