Improvements in Seed and Manure Drills.
I, JOSEPH WILSON, of Cromer, near Stevenage, in the County of Hertford, Farmer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to drills for sowing or distributing corn or seeds and manure,
and has for its chief objects to facilitate turning at the headlands and to regulate the
pressure upon the coulters and consequently also the depth at which they work, and
also to allow the coulters to rise and fall independently of each other.
According to my invention the steerage frame of the machine is mounted at the
back upon a swivel wheel arranged in conjunction with a lever whereby the drill box
and coulters can be lifted, thereby facilitating turning.
The said lever has combined with it means for setting it in several positions in order
to bring more or less of the weight of the drill on the coulters and so regulate the
depth at which they work.
The drill box and coulters are mounted upon the main frame which can be moved
independently of the steerage frame.
I also provide for the independent movement of the coulters by an improved
arrangement of levers.
Suitable draught rods are arranged so that the horses can turn the drill at the
headlands.

Improvements in Seed and Manure Drills.
1, JOSEPH WILSON, of Wakeley, near Buntingford, in the County of Hertford,
Farmer, formerly of Cromer, near Stevenage, in the same county, 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 :-
My invention relates to drills for sowing or distributing corn or seeds and manure,
and has for its chief object to facilitate turning at the headlands and to regulate the
pressure upon the coulters and consequently also the depth at which they work, and
also to allow the coulters to rise and fall independently of each other.
According to my invention the steerage frame of the machine is mounted at the
back upon a swivel wheel arranged in conjunction with a lever whereby the drill box
and coulters can be lifted, thereby facilitating turning.
The said lever has combined with it means for setting it in several positions in order
to bring more or less of the weight of the drill on the coulters and so regulate the
depth at which they work.

independently of the steerage frame.
I also provide for the independent movement of the coulters by an improved
arrangement of levers.
Suitable draught rods are arranged so that the horses can turn the drill at the
headlands.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which :-
Figure 1 is a plan of a drill having my improvements applied thereto.
Figure 2 is a side elevation of the same partly in section on the line 2-2
Figure 1.
Figure 3 is a rear view drawn to a larger scale than Figures 1 and 2 of the
arrangement of levers for carrying the coulters.
a is the main frame of the machine carrying the seed box and the coulters the
said frame being mounted on the axle d of the travelling wheels e. is the
steerage frame which at its front end is supported upon the axle d and at its
rear end is carried by the swivel wheel g. his the lever arranged in conjunction
with the swivel wheel the said lever having one end shaped to form a handle
whilst the other end is connected by a link k to the arm rigidly attached
to the main frame a in such a manner that when the lever h is moved in one
direction or the other the position of the main frame relatively with the steerage
frame will be altered in order to move the coulters relatively with the ground to
regulate the depth at which they work. As in using the drill the steerage frame f
has a lateral movement relatively with the main frame which movement would, unless
snitable provision was made to prevent it, twist the link or the lever hand
arm connected therewith, I advantageously make the said link in three sections as
shewn in Figure 2 the central section being pivotally connected to the two end sections
as shewn. To permit of retaining the main frame and consequently the coulters in
any position to which they may be adjusted I arrange in conjunction with the lever
a segment m between the two sides of which the lever moves, the said segment having
in it a series of holes n, n for the reception of a pin for retaining the lever in the
required position. At the two ends of the segment m also provide two
catches o, o for retaining the lever in either of its extreme positions the said lever
being held in engagement with the said catches by springs such as p, p as clearly
shewn in Figure 1. When the lever h is in engagement with the catch o¹ as shewn
in Figures 1 and 2 the coulters will be lifted clear of the ground for travelling.
When, however, the lever his pushed over into engagement with the catch o the
coulters c will be brought to bear hard upon the ground the swivel wheel being at the
same time slightly raised from the ground so that the whole weight of the frame
is upon the coulters. 9, 9, 9', q, q3 are levers or bars by means of which the coulters
are carried. The arrangement of the said levers will be readily understood by
reference to Figure 3 wherein it will be seen that the uppermost lever q is pivotally
carried upon the main frame a whilst the coulters c, care pivoted in pairs to the
levers or bars 92 the said hars being pivoted to downward extensions q, q on the ends
of the bars q', q' which bars in their turn are pivoted to downward extensions 9 on
the ends of the bar q. By this arrangement of the coulters any movements which
are imparted to any one coulter by meeting with obstructions are only communicated
to the other coulters in a very much reduced degree whereby the said coulters run
much more steadily than heretofore.
The arrangement of the draught rods which I advantageously make use of will
be clearly understood by reference toi Figures 1 and 2 where it will be noticed
that the draught rod proper which is indicated by the letter r is pivoted at its
rear end to the main frame a whilst at its front end it moves in a guide s arranged
at the front end of a frame t projecting from the steering frame.
It will be
understood that with this arrangement the pull of the horses in turning causes the
draught rod r to bear against one end of the guides the pull being transmitted

page_text: directly to the steering frame through the medium of one of the rods of the
frame t, t.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a seed or manure drill the combination with a steering frame mounted at
its front end upon the main axle and at its rear end carried by a swivel wheel of
a main frame carrying the seed box and coulters and adapted to be adjusted relatively
with the steering frame by means of a lever such as h, substantially as described.
2. In a seed or manure drill the arrangement of bars or levers for carrying
the coulters, substantially as described with reference to Figure 3 of the accompanying
drawings for the purpose specified.
3. In a seed or manure drill the arrangement of the draught rod in connection
with an extended frame such as t, substantially as, and for the purpose described.
4. The improvements in seed and manure drills, substantially as hereinbefore
described and illustrated in the accompanying drawings.
