Bahr, Doylestown, Wis. ’ Application January 14, 1937, Serial No. 120,60I ‘ 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. 10 ~\ , 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 90 ' I . v tions may be used in V-formation as shown in full 11 lines in Figure 2 or may be used in a single line depending on whether the snow is to bethrown 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: embodiment. disposed centrally and longitudinally of‘the' plow / a I I In said drawings:— Figure 1‘ is a side elevation of my improvements 3-3 of Figure 2; ' . ' Figure 4 is a detail ‘section taken on the line 4-4 of Figure 1; V Figure 5 is a fragmentary end elevation of the forward portion of the device; and Figure 6 is a detail section taken on the line 30‘ 6—6 of Figure 2, being on an enlarged scale. Referring speci?cally to the drawings wherein like reference characters designate like or similar 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. 45 - 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 a depending stud 25 is fastened or cast integral, and which stud travels longitudinally in a slot 26 Figure 2 is a plan view of the parts of Figure l ; Figurev 3 is a detail section taken on theline 40 adjustment. description following taken in connection ‘with accompanying drawings illustrating an operative shown attached to a tractor; 25 16 at the rear thereof, the parts 2|’ sliding along 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 at 42. 2, ‘. 2,112,131 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 III 10 adjusted positions to the plow blade. 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. ' I claim as my invention: 1. Apparatus of the class described comprising a plowblade, moldboard sections thereon, said blade having a longitudinal slot, a stud disposed in saidslot, means carried by the stud overlapping a the upper and lower surfaces of the plow blade, means on the stud hinging the adjacent ends of the moldboard sections together, and means to secure the moldboard sections in adjusted posi tions.‘ 2.
