These improvements especially relates to such a construction as is that the equipment provided with a material support shaft at the rear edge position and a feed-out roller at the middle position is equipped with a pair of needle wheels symmetrically located so that they correspond to both selvages of material mounted on the material support shaft at the middle parts on the equipment body and can independently freely rotate and that, under such conditions, the selvage portions of materials pass on the needle wheels semicircularly as being caught on the wheels.

  • Patent number: 4446639
    Abstract: An improved angling snow blade, of the type which pushes snow to the left or right as the supporting vehicle alternates directions across an area to be cleared, has a right (28) and left (29) side panel attached to hinge about the upper edge of the blade, whereby wider swaths can be taken as a result of either side panel blocking the snow from previously cleared areas. A removable bottom panel (31) hingedly attached at its leading edge to the lower leading edge of the side panels enables the improved blade to carry snow from one location and dump it in another and to pull snow away from vertical obstacles, particularly those surrounding corners.
