Improvements in Digging Ploughs.
I, THOMAS WATSON, of Alma Iron Works, Spilsby, in the County of Lincoln,
Agricultural Implement Maker, do hereby declare the nature of this invention to
be as follows:-
My invention relates to digging ploughs and has for its object to provide an
improved construction of parts which are interchangeable.
The share or point which in side view is somewhat of a V-shape is adapted
to fit onto a nose which is of rectangular shape in transverse section and tapers
forwardly.
Each side of the V has formed in it a right angled notch, one notch fitting upon
the outside top edge of the nose and the other upon the inside bottom edge thereof.
Each side of the share or point is also made flat so that when in position it forms a
continuation of the land-side.
The wing of the share is curved on its two surfaces so that either face forms a
continuation of the surface of the mould board and the ends are bevelled in opposite
directions so that either may fit against the share or point according to the side of
the wing which is uppermost.
The land-side which I use is provided with double flanges which form duplicate
soles or slades and the ends are bevelled to suit the pitch or curve of the mould
board or breast, so that when one flange and one end of the combined land-side and
sole becomes worn it may be turned round and over to present new surfaces.

Improvements in Digging Ploughs.
I, THOMAS WATSON, of Alma Iron Works, Spilsby, in the County of Lincoln,
Agricultural Implement Maker, 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 digging ploughs and has for its object to provide an
improved construction of parts which are reversible.
The share point which in side view is somewhat of a V-shape is adapted to fit
onto a nose which is of rectangular shape in transverse section and tapers forwardly,
and each side is made flat so that when in position it forms a continuation of the
landside.
The share wing is flat or slightly curved on its two surfaces so that either face
forms a continuation of the surface of the mould-board and the ends are bevelled in

page_text: opposite directions so that either may fit against a coulter piece or throat piece
according to the side of the wing which is uppermost.
The landside which I use is provided with two flanges which form duplicate soles
or slades and the ends are bevelled so that when one flange and one end of the
combined landside and sole become worn it may be turned end for end to present
new surfaces.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which :-
G
Figure 1 is a side elevation of the body of a digging plough having my improve-
ments applied thereto, the breast or mould-board being removed:
Figure 2 is a plan of the parts shewn in Figure 1; and,
Figure 3 is an elevation of the reverse side to that shewn in Figure 1:
Figures 4 and 5 are respectively a side clevation and plan of the frame of the
plough body:
Figures 6, 7 and 8 are respectively a rear elevation, a side elevation and plan of
the share point:
Figures 9 and 10 are respectively a side elevation and plan of the coulter piece or
throat piece which I use:
Figures 11 and 12 are respectively an end view and plan of the share wing;
and,
Figures 13, 14 and 15 are respectively a side elevation, a plan and an end view
of the landside with duplicate soles.
a is the plough frame having the wing a¹ to which the mould-board (not shown)
and share-wing are attached and the nose a for carrying the share point, which
nose at the extremity is rectangular in transverse section. On the landside of the
frame is also formed a projecting part a³ against which some of the parts abut
or rest.
b is the share point, c the coulter piece or throat piece, d the share-wing, and
e the landside having the duplicate soles f, f.
The share point 6 has the rectangular socket 6' adapted to fit the nose a' and at
the two sides of the socket the two arms 3, 3 one of which projects upwardly aud
the other downwardly, as shewn in Figures 6 and 7, and each of which on its top
surface is curved to correspond with the sweep of the front of the frame a, as shewn
most clearly in Figure 3. Each arm is also bevelled or chamfered off on its
outer curved surface, as shewn in Figures 6 and 7, to correspond with the sweep of
the coulter-piece, and is provided with a hole & for enabling the share point to be
When the share-point
fixed by means of a peg driven through it into the frame a.
is in position one armrests upon the projection a³ and the other extends under
the wing a¹ of the frame a. At the root of each arm ³ is formed a recess 6 to
receive the nose of the coulter piece or shield c shewn in Figures 9 and 10 in which
the said nose is indicated by the letter c'. This coulter piece which fits over the
front of the frame a is bevelled on its front surface to correspond with the sweep of
the mould-board which abuts against it and at the side is of a thickness that its face
will be in the same plane as the surface of the projection a³ ³ is a countersunk
hole for fixing the coulter piece c by a bolt.
The share-wing d is slightly curved on its upper and lower sides as shewn in
Figure 11 to correspond with the sweep of the mould-board (or it may be made flat)
and is bevelled at its ends as shewn in Figure 12 to lie against the coulter or throat
piece c, as shewn most clearly in Figures 1 and 2. As shewn the said share-wing
is provided with a double countersunk hole d placed at the centre of its length so
as to correspond with another hole in the wing a¹ whichever side of the share is
uppermost. If desired, however, two or more of such holes may be formed.
The landside e has the duplicate soles f, f so arranged that when the said land-
side is turned after one sole or one end of the landside is worn the other sole will
take its place; the ends also are bevelled to fit against the projecting piece a on
the frame a, as shewn in Figure 3.

page_text: 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 :-
Constructing the share point, share-wing and landside of digging ploughs so that
when worn on one surface or part they may be turned to use the reverse surface or
part, substantially as hereinbefore described and illustrated in the accompanying
drawings.
