Hand operated wheeled v-blade snowplow

Claim 1

A snowplow comprising a V-shaped scraper blade having a forward apex and rearwardly diverging side portions, said side portions being curled outwardly along the upper rear end portion with a progressively increasing curl from front to rear thereof to provide a concavely curved moldboard to move the snow laterally outwardly at the rear of the blade, said blade being made of a relatively thin, rigid plate type material, a front wheel and a pair of rear side wheels mounted on said blade between said side portions, said front wheel being rearwardly of the forward apex in a centered position and said rear wheels being located equal distances on opposite sides of the longitudinal axis of the blade at the rear end of the side portions for a balanced support of the blade, said blade having a resilient surface-engaging bottom molding portion with a flat bottom surface and an upwardly and inwardly inclined lip portion forming a wedge-like member to move the snow, said front and rear wheels having bottom peripheral surfaces disposed in substantially the plane of the bottom surface of the molding portion, a lateral shaft extending transversely between said side blade portions having end portions coupled to the inner faces of said side blade portions to limit lateral spreading between said side blade portions, a push handle pivotally connected to said support member and extending rearwardly therefrom, an alignment wheel pivotally connected to said support member and extending rearwardly therefrom, a line connected between the front apex portion of the blade and the handle to elevate the front of the blade by pivoting the handle rearwardly and downwardly, and a line connected between the handle and said alignment wheel to selectively elevate the wheel by pivoting the handle forwardly and upwardly.
