ABSTRACT:
A guide for pitching interlocking piles has a carrier with a clamp at its upper end with positive gripping elements for the bottom edge of a pile to be pitched. A pair of pivoted shafts at the lower end of the carrier have engagement rollers conforming to the profile of opposite faces of the lateral edge region of the adjoining pitched pile. The shafts are pivoted apart to position the guide on said pitched pile and the rollers are then engaged with said pile by pivoting the shafts to parallel positions. Spring biassing on the guide urges the edges of the piles into lateral alignment for interlocking engagement when the pile to be pitched is lifted above the pitched pile.
