This invention relates to improvements in snowpiows. One object of the invention is to provide a snowplow that is readily attachable to a motor vehicle or the like, by novel means. I
Another object is to provide a snowplow of this character that is supported as a cantilever on a motor vehicle.
A further object is to providea snowplow that is readily adaptable to various types of motor vehicles.
A still further object is to provide means for attaching such a snowplow to a motor vehicle that will permit a limited vertical movement of the plow with reference to the vehicle, to facilitate the plow passing over immovable obstructions in its path. it
Still another object is to provide a snowplow that can be used to discharge snow at both sides and that'also may be adapted to discharge at one side only.
A further object is to provide in a plowof this character, wings that are particularly well adapted to discharge snow or the like in an unusually efficient manner.
Other objects and advantages reside indetails of design and constructionwhich will be more fully disclosed in the following description and in the drawings wherein likeparts have beensimilarly designated and'in which: 5
Figure 1 is a plan view of a snowplow that is constructed according to the present inventive concept; Figure 2 is a side elevation of the plowshown I in Figure 1;
along the line 3-3 of Figure 1; V Figure 4 is a fragmentary, sectional viewtaken 'alongthe line 4-4 of Figure 1; I Figure5 is a fragmentary view of a modified form of the invention;
Figure 6 is'a fragmentary plan view illustrating the specific details of a preferred form of the invention; 1
Figure 7 is a fragmentary view illustrating another modification of the invention;
Figure 3 is a fragmentary, sectional viewtaken Figure 8 is a fragmentary view taken along the a line 88 of Figure 1; and I Figure 9 is a fragmentary view taken along the 3 line 9--9 of Figure 1.
to be attached to the front axle of the motor ve- In the drawings, reference characterIS denotes a central beam which is preferablymade telescoping to facilitate attachment and removal, as shown at IS. A pin or pins I'I, Figure 3, may
be'inserted in holes I8, Figure 1, in the tele- 5 scoping beam |5--|6 to hold the same against separation during backward movement.
iron or steel construction, but obviously, it could bemadeof other material and/or cross sectional 15 shape, as preferred.
The vertical support I9 is adapted to pass through anapertured bracket 2| on a bar 22 that isto be afiixed to the regular bumper 23 of any motor vehicle 24. The bar 22 may conveniently 0 be attached to the bumper 23by means of clamps or clevises 25. I
The rearward end of the beam I5 is adapted hicle, as indicated in dotted lines at 29. A con- 5 venient means of attaching therearward end of said beam to said axle is by means of a clevis 21. Pins 2|a may be inserted through selected apertures in the support I9 above and :below the bracket 2| to hold the beam I5 in a desired posi- 30 tion of elevation above the ground.
Clevis 21 effects a loose connection of the rear end of beam I5to the front axle of the ve- A clevis is inherently a means for loosely connecting two members. Furthermore, referring particularly to Figure 9, the square aperture adjacent the lower portion of clevis 21 and below axle 26 provides a loosely fitting entrance for the extreme rear end of beam I5 which is reduced in size as clearly shown in Figure 2 to fit freely and loosely into said aperture in the lower pin may be positioned slightly below the 45 bracket to permit limited relative movement of the vertical support I9 which supports the beam [15, with reference to the bracket 2| and the car bumper. Such movement permits the plow assembly as awhole to rise slightly over immovable 50 objects in its path, such as, for instance, outcropping stones in a roadway. Furthermore, the
inherent resiliency of the sprung portion of the motor vehicle, which includes the bumper, permits a certain amount of upward movement of the snowplow since said plow is supported on the bumper. Obviously, the bumper of a typical moto the spring mounting of the frame of the vehicle. An important advantage is effected by supporting the present plow on the bumper of a typical-motor vehicle.
In the preferred form of the present invention, the beam l5-l8 carries a pair of angularly related blades 'or wings 28 that are preferably joined at theouter end of the beam |5l6, at a 90 angle with reference to each other. Apiece of standard angle iron, shown at 29, may be used to overlie the vertex of the angle of the wings 28.
A runner-like member 30 may be provided adjacent the vertex of the plow to facilitate its riding over an immovable obstacle in its path- A cross member 3| may be supported on the beam IS-l8 to connect at its extremities with the side.
wings of the plow, 28, to maintain their angular relationship.
Toward the rearward ends of the respective wings 28 are apertured supports 32, shown best in FigureB. Supports 32 are attached at selected elevations to angle brackets 33 that are conveniently attached adjacent the outer extremities of the bar 22. The supports are attached to the wings 28 of the plow by means of bolts or the like, shown at 32. Eyes 35 in the respective supports 32 fit around the respective bolts 34 to permit limited vertical movement of the wings 28 with reference to the operating vehicle, to facilitate the passage of said wings over immovable obstacles. The rearward extremities of the wings 28 are preferably cut at an angle of about 45, as best shown at 36, Figure 8. Metal runners indicated at 31, may advantageously be used along the lower edges of the wings 28.
Obviously, the form of the improvedsnowplow illustrated in Figures 1 and 2 would be effective for discharging snow or other moved material, at both sides as the plow is driven by the motor vehicle.
In the, modified form shown in Figure 5, a socket 38 is adapted to be placed on the forward end of the beam IS. The socket 38 has an angle plate 38 to which a single blade or wing 28a may be attached, thereby providing a plow, earth mover, or the like, that is adapted to discharge at one side only. It will be understood that in the. form of the invention illustrated in Figure 5,
the means for supporting the beam [5 would be similar to the supporting meansvhereinaboveset forth. Braces not shown, could be readily attached to the blade or wing 28a adjacent the extremities thereof and connecting with the bar" on the bumper 23, to provide additional support.
In Figure 6, a socket 38a is provided with an angular flange 88 to which the wings 28 maybe conveniently attached to form the above described V,-shaped plow arrangement.
In Figure 7, a socket 88b is provided with a flange ll. to, which straight blade 42 may conveniently be attached for moving snow, earth or the like. Thus by providing a plurality of sockets 38, 38a and 38b, this improved material mover can be adapted to various types .of work according to varying operating conditions. 7
The use and operation of the improved snowplow appears obvious. The bar 22 may be af- Since the plow is supported in front of the motor vehicle as a cantilever, no portion thereof drags upon the surface over which the plow is moved. There normally is a definite space between the lower edge of the plow and the surface of the ground, as clearly illustrated in Figure 2. If and when an obstacle such as a rock, is encountered, the plow will normally slide thereover, being facilitated in such a function by the runner-like point 30 and the movable supporting mechanism illustrated in Figure 8. This improved plow may, therefore, be operated with a minimum of ;power and at a relatively high speed, due to the fact that there is no frictional drag ofthe plow on the surface of the earth.
The angular outward extremities of the plow blades or wings 28 as shown at-36, Figure 8, have been found to greatly facilitate the flow of material off of the plow. These angular ends provide a discharge for moved material and they reduce the amount of power required to move the plow against the resistance of such material. Furthermore, the banks formed by the material being moved at either extremity of the plow blades, 'aregraded outwardly from the plow so that there is definitely less tendency for the material to fall-or slide back into the cleared area.
While this specification discloses preferred means for reducing the present invention to practice and a preferred embodiment of the invention, changes may occur to those skilled in the art and may be made within the scope of the appended claims, without departing from this inventive concept.
formation, means for loosely attaching the rear of thebeam element to the front axle of a motor vehicle, a bracket attached to the front bumper of the motor vehicle, means for loosely supporting the beam element on said bracket for limited up and down movement relative thereto, the beam element being supported as a cantilever projecting forwardly of said bumper, and means for supporting said mold boards from the bumper of the vehicle for limited relative up and down movement, the entire snowplow assembly being thus supported as a cantilever projecting forwardly of the vehicle and spaced above the normal surface of the roadbed over which the vehicle travels.
