Abstract
Abstract A device for driving stakes and the like into the ground for establishing the elevation of the stake down from the outside line of the building down to the bottom of the footer. The invention contemplates a novel structure wherein a vertical frame of suitable height and configuration is provided to guide the stake into the ground in combination with the means to impart blows to the top of the stake and measure the penetration of the stake into the ground. Suitable scales are provided for assuring that the stake is driven the desired distance.
