  • Patent number: 3956862
    Abstract: A building system uses preformed blocks which are specially designed so that they key together when stacked to resist lateral movement and thus form a sturdy, load-bearing wall which does not require any mortar. In addition to a standard block, the system includes keyable corner and partition blocks as well as a cap block to provide appropriate smooth borders for windows, doors and the like.
