Abstract
An alignment and lateral support member for use in laying common concrete blocks. The support member comprises an elongate body piece of rigid material having a length which is greater than the width of concrete blocks with which the support member is to be used. A first appendage extends from a first face of the body piece. The first appendage has a stop surface extending substantially perpendicular to the first face of the body piece, with the stop surface of the first appendage being positioned a distance from the first end of the body piece so that when the stop surface of the first appendage engages an outer surface of the sidewall of a first concrete block, with the first face of the body piece lying adjacent to the first block, the body piece spans from one sidewall of the first block to the other sidewall of the first block. A second appendage extends from a second face of the body piece. The second appendage has a stop surface extending substantially perpendicular to the second face of the body piece, with the stop surface of the second appendage being spaced from the stop surface of the first appendage by a set distance along the body piece in a direction toward the first…
