the recess 20, a post 23, is formed, conically
shaped and of proper diameter to enter the
conical opening or aperture 17 in the shank
plate. The land-side is removably secured to
5 the shank plate by introducing the tongue 13
into the recess 20 of the land-side, whereupon
the embossed surface or circular projection 21
of the land-side will enter the depression 15 in
the tongue, and the post 23 of the land-side will
to enter the aperture 17 of the tongue, as shown
in Fig. 4. By this means an interlocking con-
nection is effected between the two parts, and
a bolt 24 is then passed through the embossed
surfaces 16 of the tongue and 21 of the land-
-5 side, the head of the bolt being located in the
countersink 22, the said countersink being
preferably made square, as is likewise the
head of the bolt, the opposite end of the bolt
which passes through the land-side and the
20 tongue of the shank plate being provided
with a suitable lock nut.
From the foregoing description and the
drawings, it will be understood that the land-
side is brought in firm yet proper locking en-
25 gagement with the shank plate; and that the
land-side serves likewise as a support for the
share. It is furthermore obvious that the land-
side can be removed from the shank plate
whenever desired, and another substituted
30 therefor.
Having thus described my invention, I
claim as new and desire to secure by Letters
Patent-
