Abstract:
In a plow of the type used to clear snow and like debris from roadways and similar surfaces having a plastic moldboard secured to a rigid frame adapted to be mounted to a vehicle, said frame having at least one vertically extending brace member spaced from said moldboard to define a gap therebetween characterized in that at least a portion of said gap is at least partially filled with a resilient material, said frame including a pair of longitudinally extending mounting members vertically spaced from one another by a plurality of said brace members transversely spaced along the length of said mounting members, said moldboard connected to said mounting members and said moldboard and said brace members being inwardly curved to define said gap as an arcuate gap, said gap being substantially filled with said resilient material when said moldboard is not in contact with snow or debris and said gap progressively varies from the top to the bottom of said moldboard, said brace members being structural angle members, each brace member being orientated to have a V-shaped cross-sectional configuration with legs forming said V-shape such that said legs terminate in inwardly curved leg edges, said leg edges and the back of said moldboard defining said arcuate gap and said resilient material interposed between each of said leg edges of each brace member and the back of said moldboard to substantially fill said gap, said resilient material being a block of material within said V-shape of each brace member and extending beyond said leg edges to substantially close said gap wherein said block of material has an opening extending therethrough, said opening distorted when said resilient material is compressed.
