Patent 6843034 was granted and assigned to LG on January, 2005 by the United States Patent and Trademark Office.
A method and apparatus for constructing masonry walls made of open-celled blocks without the need for mortar between individual blocks or courses of blocks using individual C-shaped bracketed pieces that lock adjacent blocks together. The open-celled blocks must have recessed notches between the cells to receive the brackets. An alternative E-shaped bracket structure allows for defined spacing between blocks that may be used to create curves in the wall.
