5 Claims. ‘ (Cl. 37-49)
This invention relates to a snow plow and it
aims to provide a novel construction adapted to
sections 2| of such jacks are in contact with the
lower surface of the blade I6 'so that the jacks
be pushed by a‘ tractor or other source of power
20-2l may be operated to raise or lower the blade
and to‘ remove the snow withlthe expenditure
5 ‘.of less power'than heretofore.
,
r
.
It is particularly aimed to provide such a con
struction wherein the snowrvis ‘elevated in strips
and while elevated is discharged, to effect the
removal with minimum power.

It is also aimed to provide such a structure as
is capable of maximum adjustment and has mold
boards adapted to discharge to either side or to
discharge solely to one side as preferred.
Various additional objects and advantages will
15 become apparent from a consideration of the

lines in Figure 2 or may be used in a single line

to both sides of the blade or to one side only.
At the inner ends of the moldboards they are con
nected together by a hinge 24 to a leaf of which:

parts, the device comprises parallel longitudinal
beams Ill preferably of metal adapted to be fas
35 tened removably by bolts. or the like as at H to
a tract-or l2 which is representative ofany source
of power which may be used to push the improve
ments. The beams I0 adjacent their forward
ends are supported by skids or runners l3 pref
erably connected to the beams by hydraulic lift
or jack mechanism I4. In order that the beams
and skids will follow the surface from which the
snow is being cleaned, the beams are preferably
in articulate sections hinged together as at I5.

A moldboard co-acts with the blade I6 and is
made in similar sections 22, having wings 23,
thereon'beyond the blade. Such moldboard sec-7

and which stud travels longitudinally in a slot 26

the undersurface "of the blade, incidental to such
A flat or sheet-like plow blade is provided at
l6, preferably of metal and of any desired size,
the same being hinged or, pivotally connected on
blade l6. Laterally extending trunnions 21 are
provided on stud 25 and rollers 28 are journaled 20
thereon and ride on the blade _I 6 on opposite sides
of the slot 26. Below the blade l6, trunnions 29
extend laterally from the stud 25 and have rollers"
30 journaled thereon which engage the under?
surface of the blade Hi. In this manner, a can: 25
riage is provided which will enable movement of
the inner end portions of the moldboards with
minimum friction. In order to fasten the inner
ends of the moldboards rigidly to the blade IS,
a lug 3| extends from the stud 25, having a set 30
screw 32 threaded therein and adapted for bind
ing against the undersurface of the blade 16. Be
cause of the hinge connection at 24 and the fact
that the carriage is longitudinally adjustable,
the moldboards 22 may be arranged at any de 85
sired location either in V-formation or in parallel
ism to divert the snow to either side of the board
l6 as preferred.
Guides and clamps 33 are riveted or otherwise
fastened as at 34, one to each moldboard 22 and
they have bifurcations 35 interengaged with guide
rods 36 disposed below, in parallelism to and fas
tened at their ends to the blade Hi. The bifurca
tions of the clamps 33 enable them to engage or
disengage the adjacent rods 36 and such clamps
have ears 3'! in which set screws 38 or the equiva:
lent are screw threaded and adapted to bind
a horizontal axis as at I‘! to the forward ends of
the beams Ill. The forward end of the blade l6
may be reenforced with a scraper l8 whose for
against the rods 36 to rigidly hold the moldboards
in the desired positions.
ward edge is preferably sharpened as shown, the
parting strips 39, one located centrally of the
scraper being riveted or removably bolted as at
blade l6 and one adjacent each side thereof and
each being braced as by means of a bar 40 riveted
thereto as at 4| and riveted to the blade I6 as
19 to the plow blade.
Adjacent the rear of the beams 10, sections 20
55 of hydraulic jacks are attached thereto and other
Integral or rigid with the scraper I8 are vertical 60

As a result of the construction described, the
plow member or blade l6 may be disposed at any
desired angle with its scraper I8 at any suitable
elevation above the ground or surface to be
5 cleared. The source of power l2 will push the ap
paratus with the scraper l8 foremost and the
snow will ride upwardly along the blade I6,
severed into two strips because of the presence of
the parting strips 39. Such strips of snow will
10 come into contact with the moldboards 22 and
the moldboard sections together, and means car
ried by the stud adapted for binding engagement
against the blade.

3. Apparatus of the class described comprising
a plow blade, moldboard sections thereon, said
blade having a longitudinal slot, a stud disposed in
said slot, means carried by the stud overlapping
the upper and lower surfaces of the plow blade,
means on the stud hinging the adjacent ends
of the moldboard sections together, means car
be forced off of the blade I6, at an elevation higher
ried by the stud adapted for binding engagement
than the undisturbed snow, with the latter offer
against the blade, and clamp means carried by
each moldboard section to secure the same in
ing no resistance, it being understood that the

4. Apparatus of the class described comprising
IE or they may be arranged in alignmentto throw ,a plow blade, moldboard sections thereon, said
moldboards 22 may be arranged in the V-forma
15 tion so as to discharge on both sides of the blade
or cast the snow entirely to either side of the blade,
the moldboards being readily adjustable as de
scribed. When the snow rides upwardly on the,
20 blade 16, it may be turned from the same without
much power and without compacting snow in ad
Vance of the implement. In the case of snow
which is soft and dry, and resistance is not apt
to be encountered by pushing the implement for
I wardly into the same, the blade‘ H5 is lowered as
nearly as practical to the horizontal.
Various changes may be resorted to provided
they fall within the spirit and scope of the in
“
vention.
