Improvements in Plough Shares.
I, RICHARD BAWDEN of Star Plough Works, South Molton, in the County of
Devon, Implement Manufacturer, do hereby declare the nature of this invention
to be as follows :-
This invention refers to those plough shares which are fitted with loose points
and consists in making not only the share but also its loose point sufficiently hollow
to receive internal support from the main toe of the plough; and also in continuing
downwards the main toe aforesaid so that it passes not only into the share, but into
the point also.
The plough point is thus supported by the toe instead of being stayed on the back
socket of the share only, as is the usual custom.
brittle
The toe being wrought or malleable iron is capable of bearing considerable strain,
and it therefore takes the strain off the casting which, being very hard,
and often gives way under severe pressure or strain.

COMPLETE SPECIFICATION.
Improvements in Plough Shares.
I, RICHARD BAWDEN of Star Plough Works, South Molton in the County of
Devon, Implement Manufacturer, 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 is designed to supply effective support to the point of the plough
share, and refers to those shares which are fitted with loose points.
It consists in making the point hollow instead of solid as heretofore, and in
extending the main toe of the plough which passes through the back share, so that
it may also pass into and support the point. This main toe is usually made of
wrought iron steel or malleable iron, so that it will form a great addition to the
strength of the point, which being brittle cast iron, often breaks away under the
strain to which it is subjected.
I will now describe the invention with reference to the accompanying drawings in
which
Fig. 1 shows a side elevation of a back-share with the renewable point attached.
The dotted lines show the position of the toe.
Fig. 2 shows a side elevation partly in section of the back share and main toe, with
the wedge which holds the latter in position.
Fig. 3 shows the point detached, the interior cavity being shown by dotted
lines.
is the back share. b, is the main toe. c, is the renewable point. d, is the
wedge which fixes b. e, is the rivet hole in point and toe.
My improved share points may be of different forms and variously attached to the
frame of the plough.
It will be understood that both the shares and points vary considerably in shape
and may be connected to the frame in different ways, the special feature of the
invention being the hollowness of the point and the projection of the toe to enter
into and support it.

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 :-
In ploughs having shares with loose points, a hollow or recess in the point and an
extension of the toe to enter into the said recess and support the said point, as
herein described and set forth.
