Improvements in Plough Shares.
Year: 1893

Complete Specification Left, 6th Sept., 1894-Accepted, 6th Oct., 1894
Improve log shares.
We, JAMES HORNSBY, JEREMIAH MONEY, and WILLIAM GRICE, all of the
Spittlegate Iron Works, Grantham, in the County of Lincoln, Engineers, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to plough shares having separate renewable points. The
socket of the share we make open in front and it fits on to the nose of the plough
body or slipe. Both the socket and the nose terminate in front in a shoulder which
is approximately in a transverse vertical plane. The renewable point has in rear
a corresponding shoulder and the one shoulder abuts on the other as closely as may
be. The point is kept in its place by projections extending rearwards from its
shoulder, they enter the socket of the share and engage in corresponding recesses
in the nose of the plough body or slipe so that the renewable point and the nose
of the body interlock within the socket of the share. The wing of the share usually
projects in front of the shoulder and extends alongside of the renewable point.
The renewable point is in this case grooved along the side to receive the edge of
the wing part of the share and so the wing of the share serves to support the
renewable point and grass and other material is excluded from the joint.
Dated this 6th day of December 1893.

Improvements in Plough Shares.
We, JAMES HORNSBY, JEREMIAH MONEY, and WILLIAM GRICE, all of the
Spittlegate Iron Works, Grantham, in the County of Lincoln, Engineers, 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 :-
Our invention relates to plough shares having separate renewable points. The
socket of the share we make open in front and it fits on to the nose of the plough
body or slipe. Both the socket and the nose terminate in front in a shoulder which
approximately in a transverse vertical plane. The renewable point has in rear
a corresponding shoulder and the one shoulder abuts on the other as closely as
may be. The point is kept in its place by projections extending rearwards from
its shoulder, they enter the socket of the share and engage in corresponding
recesses in the nose of the plough body or slipe so that the renewable point and
the nose of the body interlock within the socket of the share. The wing of the
share usually projects in front of the shoulder and extends alongside of the
renewable point. The renewable point is in this case grooved along the side to
receive the edge of the wing part of the share and so the wing of the share
serves to support the renewable point and grass and other material is excluded
from the joint.
In the drawings annexed,
Figure 1 is a side elevation of the point, the share, and the nose end part of the
body, all in their proper relative positions. Figure 2 is a plan of the same.

page_text: Figure 3 is a side elevation of the reversible point. Figure 4 is a plan of
the same.
Figure 5 is a side elevation of the share. Figure 6 is a plan of the same.
Figure 7 is a side elevation of the nose end of the body. Figure 8 is a plan of
the same.
à is the socket part of the share, it has a shoulder a¹ in rear which fits up to a
shoulder b on the nose of the plough body. At the front of the socket there is
also a shoulder a² and against this the shoulder c on the rear part of the renewable
point abuts, bare two similar projections on the nose and the ends of these
projections when the parts are in place come flush with the shoulder a². c c¹ are
like projections on the rear part of the renewable point and these interlock with
the projections within the socket a.
a is the wing of the share, it projects in front of the socket and at c³ c² the
renewable point is grooved for the wing to interlock with it.
dd are holes to receive pins to lock the parts together.
The projections &₁₁and c'c' when they interlock occupy alternate quadrants
around the axial line and being symmetrical the point is reversible so that when
the upper face is worn it can be turned over.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is :-
1. Plough shares with projections on the renewable point interlocking with
corresponding projections upon the body or slipe within the socket of the share
substantially as described.
2. Plough shares substantially as represented by the annexed drawings.
