provide ample space for the beam 1 and
plates 2-2 to pass between the same, a bolt
7 passing through appropriate, registering
perforations in the members 4 and 5, the
5 plates 2-2 and the beam 1, for the purpose
of providing such pivotal connection, said
bolt 7 being in horizontal alinement with the
bolt 3.
The plow stock members 4 and 5 are
10 curved forwardly at their lower extremities,
and brought to a point 8, a filler block 9
formed preferably of metal, being interposed
between the ends of the said members 4 and
5 for the purpose of maintaining the same
1,5 in their required spaced relation. The filler
block 9 is preferably secured in position by
rivets 10, though bolts or other means may
be employed foi the purpose.
The plow stock members 4 and 5 are fur-
20 ther provided, at their upper ends with rear-
wardly extending arms 11, which are adapt-
ed to lie against the outer faces of the wear
plates 2-2, in alinement with the pivotal
bolt 7, and are provided with enlarged ends
25 12, provided with a vertically disposed series
of perforations 13, arranged arcuately on a
radius struck from the pivot bolt 7. The
perforations 13 are in registering relation to
suitable perforations in the wear plates and
3o the beam respectively, and which are tra.-
ersed by a clamp bolt 14, for the purpose of
preventing any swinging movement of the
plow stock, upon its pivot 7. When the
clamp bolt 14 traverses the middle perfora-
35 tion 13, the stock is in substantial vertical
position, and when the said stock is shifted
so- that the bolt 14 may traverse the upper
or the lower perforation 13, a corresponding
change in the inclination of the pointed end
40 8 of the stock is effected.
The bolts 3, 7 and 14 are preferably pro-
vided with square shanks adjacent to their
heads, as is usual in such structures, and the
corresponding perforations formed in the
45 wear plates 2 and stock members 4 and 5,
for the reception of said bolts, are prefer-
ably made square also, so that the bolts may
be introduced from either side and the
squared portion thereof properly engaged to
50 prevent the bolts from turning, as clearly
illustrated in the drawing.
Immediately in rear of the filler block 9,
the members 4 and 5 of the plow stock, are
oppositely bowed outwardly, as at 15, to pro-
55 vide for the passage of a bolt 16 which se-
cures a plow point or shovel 17 in place upon
the stock, and is also used to secure a heel
sweep 18 in position beneath and to the rear
of the said stock, when it is desired to use
s0 the same.
The members 4 and 5 are somewhat re-
duced upon their upper edges, at their lower
or forward ends, to provide shoulders 19,
wlich are located adjacent to the bowed por-
;5 Hons 15 thereof, and alined notches 20 areformed in the upper edges of the said mem-
bers 4 and 5 and in rear of the shoulders
19, for a purpose to be described.
The plow point or shovel 17, which may
be of any desired form, is provided at its 70
upper or rear edge with a T-shaped exten-
sion 21 of a width substantially equal to the
space between the members 4 and 5, and has
at its free end, outwardly extending arms
22 terminating in downwardly directed lugs 75
23. The point 17 is adapted to lie flat upon
the reduced upper edges of the members 4
and 5 and the filler block 9, with the upper
or rear edges thereof abutting against the
shoulder 19, and the extension 21 fitting be- so
tween the said members 4 and 5. a The later-
ally disposed arms 22 are then seated in the
notches 20 and the lugs 23 lie against the
outer faces of the members 4 and 5. A suit-
able, squared aperture 24 is provided in the 85
point 17, in alinement with the space formed
by the bowed portions 15 of the stock mem-
bers, for the reception of the squared shank
portion of the bolt 16, which, in conjunction
with the interlocking of the arms 22 in the o
notches 20 and the engagement of the lugs
23 with the members 4 and 5, will rigidly se-
cure the point in position. Should it be
desired to use the point 17 alone, a suitable
cross bar may be used to bear against the j
under sides of the members 4 and 5 and hav-
ing a suitable aperture for the passage of the
bolt 16 and against which an appropriate
nut may bear.
It is, however, intended to use the point 100
17 in conjunction with the heel sweep 18,
and to this end the sweep is preferably
formed with a cross bar or member 25, hav-
ing a perforation 26 at the center thereof,
for the reception of the threaded end of the 105
bolt 16. The cross bar 25 is provided with
a forward extension 27, having upon its side
edges upstanding lugs 28 adapted to engage
the outer faces of the plow stock members
4 and 5 and prevent any lateral twisting or 110
turning of the sweep upon the fastening bolt
16. The cross bar 25 is further provided
upon its rear edge with a centrally located,
upstanding lug 29 which fits between the
said members 4 and 5 and assists the first- j
mentioned lugs in preventing such move-
inent of the sweep. A nut 30 is threaded
on the lower end of the bolt 16, and bears
against the under side of the cross bar or
member 25 of the sweep and thus the said 120
sweep and the plow point 17 are effectually
held against accidental movement by a sin(e
bolt.
Between the vertically disposed portions
of the plow stock or standard members 4 and 12!;
5, there is located a colter 31 in the form of
a bar or plate of a thickness substantially
equal to the space between the said members.
This colter is provided with a-vertically dis-
posed slot 32 arranged in its upper portion, 1300
