Description

FIG. 1 is a top plan view of a shovel blade showing my new design.

FIG. 2 is a side elevational view thereof;

FIG. 3 is a bottom plan view thereof;

FIG. 4 is a sectional view thereof taken along the line 4--4 in FIG. 1; and

FIG. 5 is a fragmentary top plan view of a shovel blade showing a second embodiment of my new design, the sole difference being in the specific shape of the blade.
