encountered.

A more speci?c object of my invention is to
provide a new and improved snow plow structure »in
This application is a‘division of my application
Serial No. 57,091 on Snow moving device, ?led
January 2, 1936, which issued as Patent 2,101,666
and means for raising, lowering and supporting
on December 7, 1937.
In devices of this character it is the usual
practice to mount a heavy V-plow on a tractor
vide an improved bracing and shock absorbing
10
means for plow structures.
It isanother important object of my invention
such a structure.
'
~ An important object of my invention is to pro
and to provide means for moving the V—plow
to provide relatively resilient shock absorbing
vertically with reference to the tractor to ‘regu
late the depth of cut. These devices are particu
larly applicable ‘for use in the removal of snow
from roadways and the like. The snow, of course,
means for bracing portions of the blades .of a
snow moving device andparticularly the cutting
is light in‘ relation to its volume, particularly in
15
edgeor edges of such devices.
Otherand further features and objects of my
invention ‘will be moreapparent to those skilled
the upper portion of the layer but the lower por
in the art upon a consideration of the accom
tions may be ice or water-laden snow or slush
20 whereby the load on thelplow varies considerably
throughout the .depth of the cut, the greatest
force reaction being at and near the bottom of
the layer where the material vis ordinarily the
heaviest. The situation is materially aggravated
25 when ‘obstacles such as rocks, culverts and the
like are encountered.
V
The conditions abovementioned are productive
of numerous problems. The plow must have a
large ‘area both in the vertical and horizontal
3.0 direction in order that the maximum cut, .both
in width and depth, may be made and, while the
force reactions at most points of the blade ex
cept near the ground are not particularly heavy,
the blade itself must be enabled to meet and
35 withstand heavy stresses at all points on its sur
face and thus the blade itself is necessarily a
large heavy structure which must of itself be in
herently stiff and self-supporting.
The problem of supporting and raising‘ and
40 lowering ‘this heavy blade structure and meet
ing the various stresses encountered brings 'up
problems of furnishing supporting and actuating
means which will properly actuate the plow and
meet the stresses encountered. The fact that
the force reactions‘ or ‘stresses vary from top to
bottom of the layer of material being worked
upon‘also produces problems in devising struc
tures enabled to withstand these loads.
Furthermore,‘ in' operating a ‘massive ‘tractor
and .plow of this character, when obstacles such
as, a culvert or the like are met tremendous blows
are transmitted to the plow andparticularly the
cutting edge thereof.
It is accordingly an object of myinvention to
5.5. provideaplow structure which is relativelylight
panying drawing and following speci?cation,
wherein is disclosed several exemplary embodi 12D
ments of ‘the invention, with the understanding,
however, that such changes may be ‘made therein
as fall within the scope of the appended claims
without departing from the spirit of the inven
tion. ‘The device may be used or adapted for use
for other purposes.
In said ‘drawing: .

Figure 1 is a view in perspective of a snow
plow in which a V-blade or plow, constructed
according ‘to one embodiment of my invention, A
has been incorporated. The V~plow is in lowered
position.

Figure 2'is:a view in perspective of the V-plow
of the device shown in Figure .1 taken behind

Referring nowto the drawing, the V-plow, in

the tractor, side frames |_2,-on eitherside of the

I
The side frames 12 are engaged to the lower
25 rear ends of the V-plow l?and it is apparent that
pivotal movement of the plow and plow sup
porting structure, about the stub shafts I 3, will
result in vertical movement of the V-plow to
regulate the depth of the cut. The means for se
curing vertical movement of the V-plow is indi
cated generally at 29 but, since this actuating
mechanism also forms no part of my present in
vention, it will not be further explained except to
describe the connection between this actuating
35 mechanism and the plow blade. The actuating
tions are bent back slightly as indicated in Fig 20
ure 4 to give better penetration to the cutting
edges 33. The intermediate plate 38 acts as a
strut anchored at its upper end to the reinforc
ing beam 34 which strut resists the force set up
by the cutting action of the plow. Since both
the plate 38 and mould boards 2'! and 28 will de
fleet, the resistance to de?ection increasing in
ratio to the de?ection, these parts act as a shock
absorbing means for absorbing the shocks en
countered by the plow.

The upper edges of the mould boards or main
sheets 21 and 28 are stiffened by means of angle
plates 39 and 48 and the upper edges are addi

55 the V-plow to be used for its full half width.
This divider plate is preferably straight along its
entering edge 32, but the entering edge is raked
rearwardly to cause lifting as well as dividing of
the snow ahead of the plow thus assistingin
breaking it and dividing it. The divider plate
3| is located between the abutting front inner
ends of the mould boards 27 and 28 and thus af
' fords a valuable stiffening means for the front
or entering edge of the V-plow.
The lower edges of the mould boards 21 and
28 are preferably reinforced by means of cutting
edges 33 of molybdenum steel or other hard,
wear-resistant material, secured to the mould
boards by bolts 35 or the like. The cutting
70 edges of the mould boards 21 and 28 are ad
ditionally braced and resiliently reinforced by

reinforced members 44 serve notonly to brace the
rear ends of the mould boards against twisting
and rectilinear acting stresses but also serve as
means for receiving receptacles 46 in which the 60
levers or side frames l2 are secured, the brackets
48 being secured within the rear faces of the ver
tical box members 44 by welding or in any other
suitable manner.
The receptacles 46 are box-like members which 65
abut the rear faces of the mould boards 21 and
28 within the bracing members 44, extending
through the rear walls of these members, and.
projecting rearwardly therefrom to form sockets
in which the main frame members l2 may tele 70

The inside faces of the boxes 44 serve also as
a means for mounting the pivot brackets 41 in
which pins 48 are pivotally engaged. The pivot
pin brackets 41 are built-up structures comprised
of horizontally extending panels (is, secured to
the side walls of the box members 44 and to the
inside faces of mould boards 21 and 28, and
10 braces or gussets 5! are secured to the inside faces
of the box members 44 and to the under side of
the panels 49. These brackets and pivot pins
form a means of attachment to a. lifting device
such as a hydraulic jack 29 for raising or lower
ing the mould boards to regulate the depth of
cut. Raising and lowering of the V-plow is ac
complished by means of links which are opera
tively connected to the actuating mechanism 29
and to the pivot pins 48. The actuating mecha
nism is such that not only will the links act to
raise the V-plow and hold it in any desired posi
tion, but down pressure may be applied to the
links to drive the V-plow downward as desired.
It is desirable, in some types of snow removal
work, that the V-plow be permitted to ?oat freely
and its position with reference to the ground be
determined by means of one or more shoes.
In
the structure here illustrated, a single long wide
shoe 52, having a plurality of soles or runners 53
is employed at the nose of the V for adjustably
supporting it with reference to the ground sur
face. The shoe 52 is pivotally engaged at its
front end to suitable brackets 56 within the nose
of the V. The plate or shoe 52 is pivotally en
gaged to support members 59 at each of the rear
corners of the plate 52. These support members
59 project upwardly adjacent to the rear faces of
the cross beam 42 and pass through adjustment
brackets 6| which are secured to the rear faces
of the cross beam 42.
It is apparent that I have provided a relatively
light v-plow structure which may be made up of
standard channels and plates, but which is in
herently stiff and sturdy, to meet the many and
varying stresses impressed upon it in use. The
V-plow is readily released from its supporting
structure by removing the pins 135, 4B and the
bolts or other means employed for securing the
braces 2A to the upper edge of the plow.
It is apparent that modi?cations may be made
by those skilled in the art and such modi?cations
may be made without departing from the spirit
and scope of my invention as set forth in the
appended claims.
