Improvements in or applicable to Corn and Seed Drills.
1, JOSEPH WILSON, of Cromer, near Stevenage, in the County of Herts,
Farmer, do hereby declare the nature of this invention to be as follows:-
This invention relates to an attachment applicable to corn and seed drills, the
invention having for object to provide means to facilitate the turning of the drill
at the land's end.
My attachment consists of a lever connected to an elbow joint working on the
frame of the drill, and of a swivel wheel so arranged that, when it is required
to turn the drill, the lever is operated so as to bring the swivel wheel on the
ground at the same time lifting the drill out of work and allowing the same to be
turned on the swivel wheel.

I, JOSEPH WILSON, of Wakeley, Buntingford, formerly of Cromer, near
Stevenage, in the County of Herts, Farmer, 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 an attachment applicable to corn and seed drills, the
invention having for object to provide means to facilitate the turning of the drill
at the land's end.
My attachment consists of a lever provided with an elbow joint and working on
the frame of the drill, and of a swivel wheel so arranged that when the lever is
operated to depress the swivel wheel the drill will be lifted out of work.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is a side elevation shewing the application of my invention to the
handle frame of a drill: and,
Figure 2 is a plan of the same:
Figures 3 and 4 are respectively a plan and a side elevation shewing a special
form of draught irons which I advantageously use in conjunction with my
invention:
a, a are the side bars of the drill frame to which the handle bar b is attached in
the usual manner, and c is my swivel wheel which is mounted in the fork d adapted
to swivel in a bracket e fixed at the adjacent ends of two bars f, f the other ends of
which are pivoted upon the side bars a, a of the frame..

page_text: g is the operating lever provided with an elbow joint at h the said lever being
connected to the swivel wheel bracket e at i and to the bar b of the drill frame
at j. It will be understood that the two parts of the lever g constitute a kind of
toggle which when in the bent position, as shewn in full lines in Figure 1, will
allow the handle frame to drop to its normal working position whilst when the
lever is straightened, as indicated by the dotted lines in the said figure, the handle
frame will be lifted so as to lift the drill coulters out of the ground and thereby
permit of the drill being turned with facility.
To prevent the two parts of the lever g from going beyond the straight position
the end of one part is bevelled as at k and designed to bear against a correspondingly
inclined surface I on the other part.
In the foregoing description I have assumed that the swivel wheel is always
running upon the ground whether the frame is in its working position or in the
raised position, it will be obvious, however, that when the lever g has been moved
sufficiently far to lower the handle frame to bring the coulters into the ground the
continued movement of the said lever will serve to lift the swivel wheel off
the ground.
I advantageously employ in conjunction with my invention an arrangement of
draught irons which will be readily understood by reference to Figures 3 and 4.
The rod m which is provided with a ring or eye for the connection of the draught
book is loosely connected to the side links n, n as shewn so as to permit of the
bar m being capable of swinging through a limited distance horizontally in order
that the irregularities in the pull exerted by the horses may not affect the steering
of the drill when in work.
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 corn or seed drill the combination with the handle frame of a swivel
wheel carried by bars pivoted to the handle frame, and of a lever containing an
elbow joint and connected to the handle frame and to the swivel wheel bracket,
substantially as, and for the purpose, described.
2. The combination with a corn or seed drill of a swivel wheel in connection
with the handle frame, arranged and operating substantially in the manner
herein before described and illustrated in the accompanying drawings, for the
purpose specified.
3. The combination with a corn or seed drill having a swivel wheel as mentioned
in the preceding claiming clauses of an arrangement of draught irons, substantially
as described with reference to Figures 3 and 4 of the accompanying drawings..
