  • Patent number: 5125162
    Abstract: A unique brick alignment clip is disclosed comprising a top face, and front and rear faces positioned on faces of a brick. A line extends between adjacent clips to align a plurality of bricks. In one aspect of the present invention the front of the clip has irregular toothed surfaces which are drawn into the laterally outward face of the brick to secure the clip on the brick. Further, a thumb screw in the rear face also helps secure the clip on the brick. In another feature of the present invention the line extends through a central slot in the front face and around front and rear ears to secure the line to the clip. The ears are speced laterally from a central axis of the clip, while the center slot is aligned with the central axis. The line extends rearwardly from the center slot and around the ears, such that the direction of the application of force from the line to the clip is predictable.
