Abstract
A shovel apparatus for digging holes has an H-shaped frame providing at one end, a handle integrally joined to the frame, and at the other end, a blade mounting support. A pair of spaced apart shovel blades are pivotally engaged with the blade mounting support for drawing the blades from essentially parallel rest positions, toward each other, to form a modified cone-shaped enclosure. A draw arm assembly is engaged for sliding within a pair of opposing slots in the H-shaped frame. The draw arm assembly is engaged with the shovel blades through a pair of links to move the shovel blades toward each other when the draw arm assembly is pulled toward the handle.
