and the inner face of the said landside
flange being arranged flat against the land-
side face of the standard. The plow point
or share is provided at the angle formed by
5 the landside flange and the working plate
with a tapering recess or socket 24, com-
posed of angularly related portions 25 and
26, formed in the lower face of the working
plate 22 and in the inner face of the land-
10 side flange 26 and corresponding in shape
to the tapering projection 14. The plow
point or share is applied to the standard in
the usual manner, and the tapering projec-
tion fits into the tapering recess or socket
15 26, and interlocks the plow point or share
with the standard forming a dove-tail lock,
and wedging the plow share or point on the
standard. The plow share or point is se-
cured upon the curved face 13 of the stand-
20 ard by means of a bolt 27, passing through
registering perforations 28 and 29 of the
plow point and the standard. The distance
across the space between the side edges 18
and 21 of the tapered projection is greater
25 than the distance across the space between
the same at the bottom of the said flanges
19 and 21, as clearly indicated in Fig. 3 by
the dotted lines a and b, so that it is impos-
sible to disengage the plow point from the
30 standard by either an upward movement or
a lateral movement, and the strain on the
plow point incident to its use tends to hold
the plow point on the standard and main-
tains the same firmly in its interlocked re-
35 lation with the wedge-shaped projection.
By this construction the bolt 27 is relieved
of excessive strain, and the plow point will
remain firmly in its position on the stand-
ard, even should the fastening bolt become
40 loose. In placing the plow point on the
standard the tapering lug in engaging the
tapering recess or socket 26 will force the
plow point in correct position against the
mold board and the landside flange against
45 the landside shoulder 17, and the interlock-
ing of the parts will hold the plow point in
position while the latter is being bolted to
the standard.
Having thus fully described my inven-
50 lion, what I claim as new and desire to se-
cure by Letters Patent, is:-
1. In a plow, a standard provided at the
meeting edge of its landside face and its top
face with a tapering projection extending
55 over a portion of the said top face and over
a portion of the landside face and being of
an area less than the said faces, and a share
having its landside flange fitted against the
landside face of the standard and provided
60 at its angle with a recess receiving the said
projection, whereby the share is held against
vertical movement on the landside face and
lateral movement on the top face of the
standard.
65 2. In a plow, a standard provided at themeeting edges of its top face and landside
face with a tapering projection extending
over a portion of the top face and a portion
of the landside face of the standard and be-
ing of less area than the said faces and hav- 70
ing its thicker and narrower end at the
front and decreasing in thickness and in-
creasing in width toward its rear end and
merging into the top face and the landside
face of the standard, and a share fitted 75
against the top face and the landside face
of the standard and provided in the angle
formed by its landside flange with a socket
of corresponding tapering shape receiving
the lug of the standard and interlocking the so
share with the same, whereby the share is
wedged on the standard and held against
vertical movement on the landside face and
lateral movement on the top face of the
standard. 85
3. In a plow, a standard provided at the
meeting edges of its top face andlandside face
with a tapering projection composed of an
inwardly extending top portion and a de-
pending approximately vertical portion, 90
said projection being spaced from the front
of the standard and decreasing in thickness
and increasing in width toward its rear end
and merging into the top and landside faces
of the standard, and a share fitted against the 95
top face and the landside face of the stand-
ard and provided in the angle formed by its
landside flange with a socket of correspond-
ing shape receiving the lug of the standard
and interlocking the share with the same, 100
whereby the share is wedged on the standard
and is held against upward movement on
the landside face and lateral movement on
the top face of the standard.
4. In a plow, a standard provided at the 105
meeting edges of its top and landside faces
with a tapering projection composed of an
inwardly extending transversely inclined
top portion and a depending approximately
vertical portion having the upper portion of 110
its side face inclined upwardly and in-
wardly, and a share fitted against the top
face and the landside face of the standard
and provided in the angle formed by its land-
side flange with a socket of corresponding 115
tapering shape receiving the lug and inter-
locking the share with the standard, where-
by the share is wedged thereon and is held
against upward movement on the landside
face and lateral movement on the top face 120
of the standard.
5. In a plow, a standard provided at the
meeting edges of its top and landside faces
with a tapering projection composed of an
inwardly extending transversely inclined 125
top portion and a depending approximately
vertical portion having the upper portion of
its side face inclined upwardly and in-
wardly, said projection being provided
with inclined side edges and being of a 1-392
