Abstract
Abstract A snow shovel is disclosed which is adapted to remove snow from various surfaces by pushing the shovel along the surface. Additionally, the shovel is adapted so that it may be used in a conventional manner, i.e. for use in lifting snow from one location to another. The shovel includes a handle assembly which is connected to a base which is set at a small angle to the snow-laden surface. The base is semi-circular in shape and has connected to it a vertically displaced member which is adapted to abut the snow as the shovel is being pushed.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
132 words
An apparatus for snow displacement which comprises: a semi-circular flat base plate; a curved panel having a lower edge and straight diametric edge, said panel being substantially at a right angle with respect to said base, rigidly connected to the curved portion of said base plate such that the plane of the base is at a small angle with respect to the ground, and said lower edge and said straight diametric edge being in contact with the ground when said apparatus is in use; and a handle pivotally connected to said base plate which permits an operator to push said apparatus, thereby causing the convex outer surface of said vertical curved panel to contact the snow and impact it so that the snow will flow around and be displaced by said apparatus.
Claim 2
Independent Claim
132 words
An apparatus for snow displacement which comprises: a semi-circular flat base plate; a curved panel having a lower edge and straight diametric edge, said panel being substantially at a right angle with respect to said base, rigidly connected to the curved portion of said base plate such that the plane of the base is at a small angle with respect to the ground, and said lower edge and said straight diametric edge being in contact with the ground when said apparatus is in use; and a handle pivotally connected to said base plate which permits an operator to push said apparatus, thereby causing the convex outer surface of said vertical curved panel to contact the snow and impact it so that the snow will flow around and be displaced by said apparatus.
Claim 3
Dependent Claim
111 words
The apparatus of claim 1 wherein said handle can be pivoted longitudinally with respect to said base so that it may come to rest at the center of the top edge of the vertical panel, thus allowing said apparatus to be pushed through the snow such that said diametric edge of said base plate will cut through the snow as it contacts the ground causing the snow to flow onto the base place until it contacts said vertical panel which acts as a backstop to cause the snow to accumulate within the apparatus for subsequent discharge to the side, thereby permitting the apparatus to be used as a conventional snow shovel.
