Abstract
A V-shaped under frame with a transverse rear member connected at its ends to forwardly converging side members has spaced uprights connectable to a truck. Pivots connected in aligned relation on each side member connect to ribs on the convex rear side of right and left moldboards. The inner edges of the moldboards are closely adjacent along their upper portions, but diverge along their lower portions. Backing springs on the side members bias the tops of the moldboards forwardly. A low V-shaped plow point is connected by a strut to the under frame and located within the space left by the diverging lower portions of the moldboards. Roadway engaging shoes are connected to the under frame adjacent each of its three corners.
Claims9
A V-shaped highway snow plow having a generally horizontal V-shaped under frame with a transverse rear member connected at its ends to forwardly converging side members and having laterally spaced uprights near the center of the rear member adapted to be connected to a truck, and roadway engaging support shoes depending below the frame, said plow being characterized by having:
- alined pivot supports carried by each of said side members,
- a pair of individual forwardly convex moldboards with pivot connectors on their rear sides mounted on said pivot supports, one moldboard on each side member, said moldboards being mounted independently of each other,
- a pair of spring abutments carried by said under frame in generally perpendicular relation to said side members, springs anchored by said spring abutments,
- and pressure members connected to the backs of said moldboards and co-acting with springs to bias the upper edges of said moldboards rearwardly about said pivot connections,
- the upper portions of the inner edges of said moldboards being biased to normally be in closely adjacent relation by said springs, either of said moldboards upon striking an obstruction, pivoting about its associated pivot support to compress said spring independent of the motion of the other moldboard.

- alined pivot supports carried by each of said side members,
- a pair of said moldboards being mounted independently of each other, forwardly convex moldboards with pivot connections on their rear sides associated with said pivot supports, one moldboard on each side member,
- a pair of spring abutments carried by said under frame in generally perpendicular relation to said side members, springs achored by said spring abutments,
- and pressure members connected to the backs of said moldboards and co-acting with spring to bias the upper edges of said moldboards rearwardly about said pivot connections, either of said moldboards upon striking an obstruction, pivoting about its associated pivot support to compress said spring independent of the motion of the other moldboard.
