PROVISIONAL SPECIFICATION.
Improvements connected with Plough Coulters.
I, FRANK KIRKBY, of Low Farm, Buckden, Huntingdon, Farmer, do hereby
declare the nature of this invention to be as follows:-
This invention refers to firstly, an improved shape for the coulter, and secondly,
to an improved manner of attaching the same, which will admit of the coulter being
readily raised or lowered.
The coulter is made of a thin steel blade of rectangular shape, with a point.
formed by the blade inclining towards the back. To strengthen the blade it is
made near the back with a double corrugation. The top end of the blade is formed
with an eye or ring to assist the securing. The blade is held on an iron rod which
passes through the eye, the top of the rod being formed with a clip to pass round
the back of the blade. The rod is secured in the eye by a set screw, and to the
plough in any convenient way.

Improvements connected with Plough Coulters.
1, FRANK KIRKBY, of Low Farm, Buckden Huntingdon, Farmer, do hereby
declare the nature of my 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 refers firstly, to an improved shape for the coulter, and secondly,
to an improved manner of attaching the same which will admit of the coulter being
readily raised or lowered.
To enable this invention to be properly understood I will proceed to describe the
same with aid of the accompanying drawings.
Figures 1 and 2: side and edge views of coulter and holder.
Figures 3 and 4: sections of same.
A, is the coulter made of a steel blade, slightly corrugated for strength. B, the
coulter holder, consisting of an iron rod, which is attached in any convenient
manner to a plough. Fitting on rod B, is a ring D, with set screw D¹, to secure
the ring on rod. The bottom of this rod has a turned round hook C to assist in
securing the blade while cutting, the top of the blade has a portion cut away to
enable a portion to pass through the ring D, to secure the coulter blade to rod B ;
this is done by tightening up the set screw D'. It will thus be understood the
coulter blade can be raised or lowered and secured at any desired height by simply
loosening the set screw, setting the blade, and tightening up the screw again.
