Building brick

FIG. 1, is a perspective view from the top at one end of a building brick showing my new design;

FIG. 2, is an underside perspective view from the other end of the brick;

FIG. 3, is a top plan view;

FIG. 4, is an underside plan view;

5, IS A SIDE ELEVATION; AND

FIG. 6, is an end elevation.

The characteristic features of my design reside in the provision of square beveled projections on the upper face of the brick and complementary beveled recesses on the under surface and with two apertures through the body of the brick each connecting a beveled projection with a beveled recess in the under surface.
