I, JAMES EDWARD RANSOME, of the Orwell Works, Ipswich, in the County of
Suffolk, Engineer, do hereby declare the nature of this invention to be as follows:-
My improvements relate to the manufacture of plough shares with separate points
and wings attached to that part of the share commonly known as the box. The box
which fits directly on to the nose or fore part of the plough frame, or head, consists of
a socket which slips on to the nose and is held in its place by a tension rod or through
pin, or it is made simply to fit on to the fore part of the plough frame and is screwed
thereto by a bolt passing through the upper part of the box and the frame.
On the wing side of the box part I form a projection or ledge on the top of which
the wing piece rests and is secured to it by a bolt and nut. On the front of the wing
piece I form a projection-or a recess-which fits into or on a corresponding recess or
projection which I form on the rear part of the moveable point of the share, and
which locks the two parts together. I form the point of the share in such a way that
a part of it is situated directly in front of and covers the front part of the junction
between the box and the wing and prevents any grass or roots getting into it and
wedging themselves between the wing piece and the box. On one side of the point
I form the front portion of the cutting edge of the share the line of which is con-
tinuous with the cutting edge of the wing. This point fits on to a small nose formed
on the box part of the share, and when it is secured to this nose by a pin or otherwise
it holds the fore part of the wing both vertically and laterally firmly in its place so that
one bolt only is required to secure the wing whilst the cutting edge and upper surfaces
are thereby kept in their proper positions. The upper surfaces of the point, the wing,
and the box, form one continuous curve with the mouldboard.
I make the box part preferably of cast iron and chill the upper surface to protect it
from undue wear to make it last out many new points and wings. The same arrange-
ment as regards the locking together of the point and wing may be retained, but the
back part of the wing may if desired be bolted to the front part of the mould board or
frame of the plough instead of to the box part of the share.

page_text: By this construction I form a share perfect in form, of great strength and with
cheap wearing parts.
I also in some cases fix the wing of the share to the box by means of a bolt as before
described, but instead of locking the wing to the point I cast a projecting piece on
the underside of the wing which engages with a corresponding notch or recess on the
ledge on the box part of the share, so that the front part of the wing is fixed in its
position and cannot move either laterally or vertically, a single bolt fastening it to
the box part as before; although in this case the wing is not locked to the point I
still form the point with its cutting edge in such a way that it overlaps the junction
between the box and the wing as before described.

page_text: Improvements in Plough Shares.
I, JAMES EDWARD RANSOME of the Orwell Works, Ipswich, in the County of
Suffolk, Engineer, 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 improvements relate to the manufacture of plough shares with separate points
and wings attached to that part of the share commonly known as the box. The box
which fits directly on to the nose or fore part of the plough frame, or head, consists of
a socket which slips on to the nose and is held in its place by a tension rod or through
pin, or it is made simply to fit on to the fore part of the plough frame and is screwed
thereto by a bolt passing through the upper part of the box and the frame.
On the wing side of the box part I form a projection or 'ledge on the top of which
the wing piece rests and is secured to it by a bolt and nut. On the front of the wing
piece i form a projection-or a recess which fits into or on a corresponding recess or
projection which I form on the rear part of the movable point of the share, and
which locks the two parts together. I form the point of the share in such a way that
a part of it is situated directly in front of and covers the front part of the junction
between the box and the wing and prevents any grass or roots getting into it and
wedging themselves between the wing piece and the box. On one side of the point
I form the front portion of the cutting edge of the share, the line of which is con-
tinuous with the cutting edge of the wing. This point fits on to a small nose formed
on the box part of the share, and when it is secured to this nose by a pin or otherwise
it holds the fore part of the wing both vertically and laterally firmly in its place so that
one bolt only is required to secure the wing whilst the cutting edge and upper surfaces
are thereby kept in their proper positions. The upper surfaces of the point, the wing,
and the box, form one continuous curve with the mouldboard.
I make the box part preferably of cast iron and chill the upper surface to protect it
from undue wear to make it last out many new points and wings. The same arrange
ment as regards the locking together of the point and wing may be retained, but the
back part of the wing may if desired be bolted to the front part of the mouldboard or
frame of the plough instead of to the box part of the share.
By this construction I form a share perfect in form, of great strength and with
cheap wearing parts.
I also in some cases fix the wing of the share to the box by means of a bolt as before
described, but instead of locking the wing to the point I cast a projecting piece on
the underside of the wing which engages with a corresponding notch or recess on the
ledge on the box part of the share, so that the front part of the wing is fixed in its
position and cannot move either laterally or vertically, a single bolt fastening it to
the box part as before; although in this case the wing is not locked to the point I
still form the point with its cutting edge in such a way that it overlaps the junction
between the box and the wing as before described.

page_text: DESCRIPTION OF THE DRAWINGS.
The same letters of reference refer to the corresponding parts in each Figure.
Figures 1 to 8 inclusive shew one form of my improved share. Figure 1 is a plan
of the upper side and Figure 2 plan of the under side of the share when the parts of
which it consists are put together. Figure 3 is a plan of the box part, Figure 4 a
plan of the wing piece and Figure 5 a plan of the point. Figures 6, 7 and 8 are
sections taken respectively on the lines 1. 1., 2. 2., and 3. 3. The socket d of
the box A slips on to the nose or fore part of the frame of the plough D, the box being
held in place on the frame either by a tension rod or by a pin passing through the
upper part of the box and through the nose. On the wing side of the box A is
formed a projection or ledge b, on the top of which the wing piece C rests and is
secured thereto by a bolt e. On the point of the wing piece a projection fis made
which fits into a corresponding recess in the point B, which locks the two parts
together. If preferred the projection can be made on the point B and the recess in
the wing piece C. The socket h of the point B fits on to a smaller nose a on the front
part of the box A of the share, and is secured to the nose a by a pin or otherwise and
holds the fore part of the wing both vertically and laterally firmly in its place so
that only one bolt e is required to secure the wing whilst the cutting edges and
upper surfaces are thereby kept in their proper positions. It will be seen from the
sections Figures 6, 7 and 8 that the upper surfaces of the point, wing, and box, form
one continuous curve with the mould board E and in this respect differs from my
former share patent No. 14967-1885, in which the upper surfaces of the point,
box and wing are not continuous. The same arrangements of a projection and
recess for locking the wing C and the point B together may be retained but the
back part of the wing may if desired be bolted to the front part of the mould board,
see Figure 13, a ledge or projection n passing underneath the mould board to which
it is secured by a bolt e, the upper surfaces of the mould board and the wing forming
an unbroken surface, or it may be bolted to the frame, a ledge o being formed on
the frame on which the wing rests, and to which it is attached by the bolt e Figure 14.
Figure 10 a plan of the box, and Figure 11 a plan of the wing in another arrange-
ment for holding the wing. The wing C is bolted to the ledge b on the box A as in
Figures 1 to 8, but instead of locking the wing to the point by a projection f as in
Figure 4 a recess or notch m¹ is made in the front of the ledge 6 of the box and a
projection m on the under side of the wing engages with the recess, see section
Figure 12, which is taken on the lines 4, 4, of Figures 10 and 11. The front part of
the wing cannot move either laterally or vertically, a single bolt e fastening it to the
box as before described. The box A is sometimes made to fit on to the fore part of
the frame D instead of slipping on and is retained by a bolt as in Figure 9 which is
a section taken on the line 1, 1, the attachments of the wing piece and point being
the same as already described, the modified parts being substituted for those shown in
Figure 1.
In Figure 1 it is shewn that a part of the point B is made to come directly in front
of and to cover the front part of the junction between the box A and the wing C, thus
preventing any grass or roots getting into and wedging themselves between the wing
piece and the box. The front of the point B from 3 to 2, see Figure 1, forms part of
the cutting edge of the share and is in a line with the front part of the wing from
2 to 1 which completes the cutting edge of the share.
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 in plough shares having three distinct parts, viz., box part, point and
wing, is :-
1. The box having a ledge for the wing to rest upon and to which it is attached.
2. The wing having a projection, or a recess at the front to fit into or on to a recess
in or projection on the maint

page_text: 3. The point having a recess or projection to fit on to or into a projection on or
recess in the wing.
4. The point with its front cutting edge covering the junction of the box
and wing.
5. The wing with a projecting piece on the underside to engage with the ledge
of box.
6. Plough shares substantially as described and illustrated by the annexed
drawings.
