invention to be as follows:-
Improvements in the shares & mould boards of plows. The share will be
made in 2 parts the point & the wing. The point will be made of a bar of malle-
able iron or steel. This bar will pass through a socket formed on the head or body
of the plow, & will extend 12 inches or thereby backwards beyond the socket,
through the space between the mouldboard & landside. It will be fixed when
in position by a bolted clamp close to the rear of the socket & will be further
stayed by a screw following against its rear end as the clamp might not be
sufficient to hold it in stony land. The socket through which the point will
pass will be made on a line making an angle of about 20 deg. with both the land-
side & sole plate of the plow, thus allowing the point bar to come flush with
both landside & sole plate at the point where it projects in front of them.
At this point the bar will be bent sufficiently to make it run straight with both
landside & soleplate.
By means of this arrangement the point bar can be passed forward as it is
worn & the position of the bend altered to suit, by a simple forging operation
thus giving for small cost a great amount of wearing material & at the same
time facilitating the keeping of the plow in thorough form at this part.
This joint bar will be shaped in section, the lower flange being about three
times the strength of the upper flange. This shape of section allows of a thorough
joint being made with the wing.
That the bend in the point bar may be remade easily & certainly we will make
a block or die of cast iron or such material with the exact shape of the point
recessed therein, so that when the position of the bend is being altered it may be
formed at the exact angle by being forged into the recess in this block. This
block in conjunction with the point is part of the invention & will be supplied
along with the plow.
The wing will be made of a plate of chilled cast-iron or steel of suitable
thickness & will be affixed to the body of the plow by means of a bolt or other-
wise & so shaped at its front end as to make a good joint with the point bar.
The lower landside plate as in common use will be a separate part from the upper
landside plate. The soleplate will be attached as is common to this lower landside
plate so that these two parts will practically form one piece. As the weight of
the plow is borne in most part by the sole plate the wear on it is greater than on

page_text: any other part & as the point above described will when re-shaped be exactly
the same as when new, it is clear that the point will not run in line with the worn
soleplate. To admit of adjustment we will fix the combined sole plate & lower
side plate to the body of the plow by two bolts passing through the side plate
& through short vertical slots in the body. By this means the sole plate may
be adjusted as it is worn.
The mould board of this plow differs from the ordinary mould board in that it
has the lower half of the rear end eut, leaving about 6 inches of the upper half
projecting in rear. On the lower edge of this projecting part the wear is greater
than on any other part of the mould board & to facilitate repairs at this part we
will attach a removable piece of steel plate or chilled cast iron to the lower edge
of this projecting part of the mouldboard.

WILLIAM REID, Seedsman, 8, Hadden Street, Aberdeen, ALEXANDER SIMPSON,
Blacksmith, 54, Wellington Road, Aberdeen, 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 relates to improvements in or connected with plows. The
share will be made in two parts the point & the wing. The point will be made
of a bar of malleable iron or steel. This bar will pass through a socket fornied
on the head or body of the plough & will extend 12 inches or thereby backwards
beyond the socket, through the space between the mould-board & fandside. It
will be fixed when in position by a bolted clamp close to the rear of the socket
& will be further stayed by a screw following against its rear end, as the clamp
might not be sufficient to hold it in stony land.
The socket through which the point will pass will be made on a line making
an angle of about 20 deg., with both the landside & soleplate of the plough;
thus allowing the point bar to come flush with both landside & sole plate at the
point where it projects in front of them. At this point the bar will be bent
sufficiently to make it run straight with both landside & sole plate.
By means of this arrangement the point bar can be passed forward as it is worn
& the position of the bend altered to suit, by a simple forging operation, thus
giving for small cost a great amount of wearing material & at the same time
facilitating the keeping of the piough in thorough form at this part.
This point bar will be shaped in section the lower flange being about three
times the strength of the upper flange. This shape of section allows of a thorough
joint being made with the wing."
That the bend in the point bar may be remade easily & certainly we will make a
block or die of cast iron or such material with the exact shape of the point recessed
therein, so that when the position of the bend is being altered it may be formed
at the exact angle by being forged into the recess in this block. This block in
conjunction with the point is part of the invention & will be supplied along with
the plough. The wing will be made of a plate of chilled cast iron or steel of
suitable thickness & will be affixed to the body of the plough by means of a bolt
or otherwise & so shaped at its front end as to make a good joint with the point

page_text: bar. The lower part of the landside plate as in common use will be a separate
part from the upper landside plate. The sole plate will be attached as is common
to this lower landside plate so that those two parts will practically form one
piece. As the weight of the plough is borne in most part by the sole plate the
wear on it is greater than on any other part & as the point above described will
when re-sharped be exactly the same as when new it is clear that the point will
not run in line with the worn sole plate. To admit of adjustment we will fix
the combined sole plate & lower sole plate to the body of the plough by two
bolts passing through the side plate & through short vertical slots in the body.
By this means the sole-plate may be adjusted as it is worn.
The mouldboard of this plow differs from the ordinary mouldboard in that it
has the lower half of the rear end cut, leaving about 6 inches of the upper half
projecting in rear. On the lower edge of this projecting part the wear is greater
than on any other part of the mould board, & to facilitate repairs at this part we
will attach a removable piece of steel plate or chilled cast iron to the lower edge
of this projecting part of the mouldboard.

Having now particularly described & ascertained the nature of our said inven-
tion & in what manner the same is to be performed we declare what we
claim is:-

Specification.
2nd. A plough head or body with socket to admit of share point passing
through as described.
3rd. A clamp to hold the point when in position and a screw following against
the rear end of point & cross-stay through which screw passes.
4th. The special sectional shape of the bar from which the share point is made
in so far as that shape is applied to the purpose of a share point as described.
5th. The special shape of the share wire at the front end where it forms a
junction with the point as described.
