Abstract
A belling auger includes a rotatable shaft, a main shaft extending through the rotatable shaft, a sliding sleeve mounted on the main shaft a bottom panel and a shovel rotatably attached to the rotatable shaft. Pressing the rotatable shaft down towards the sliding sleeve causes the shovel to hinge outward at the bottom of a piling hole. As the device rotates the shovel scoops dirt onto the pan, thus widening the bottom of the hole to a bell or cone shape.
