Abstract
Abstract This invention refers to a brick that may be used with other bricks having similar dimensions. While the normally exposed sides of the brick are flat, one end of the brick terminates in an angular truncate extension with the opposite end of the brick having a similarly shaped concave recess. The top of the brick has a conical shaped extension on one end and a conical recess on the other end thereof. The bottom of the brick also has a conical shaped extension on one end and a conical shaped recess on the opposite end as previously described for the top. A shoulder extends upward on one side above the top of the brick and downward on the diagonally opposing side below the bottom of the brick. The opposite side on both the top and bottom of the brick has a recess for receiving the shoulder. Holes extend through the brick from top to bottom to receive reinforcing bars therethrough.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
273 words
A brick having an oblong configuration, said brick comprising: a pair of flat parallel surfaces; a truncated angular extension on one end of said brick between said pair of flat parallel surfaces; an angular recess on the end opposite said truncated angular extension of said brick between said pair of flat parallel surfaces, said angular recess being designed for receiving said truncated angular extension of an adjacent brick; a top of said brick between said pair of flat parallel surfaces, a first end of said top having a generally conical extension thereabove and a second end having a generally conical recess therein; a bottom of said brick between said pair of flat parallel surfaces, said bottom having a conical recess located immediately below said conical extension on the top of said brick and a conical extension in said bottom immediately below the conical recess in said top of said brick, said conical extensions and conical recesses being designed to fit conical extensions and recesses of adjacent bricks; holes extending from said top of said brick to said bottom thereof, said holes being designed for alignment with holes of adjacent bricks; said truncated angular extension and said angular recess extending from said top to said bottom of said brick an upward extension of one of said pair of flat parallel surfaces above said top and a recess in the other of said pair of flat parallel surfaces below said top, said bottom having substantially identical recesses and extensions for mating with adjacent bricks; and abutting shoulder means between said pair of flat parallel surfaces and both said truncated angular extension and said angular recess.
Claim 2
Dependent Claim

A brick having an oblong configuration, said brick comprising: a pair of flat parallel surfaces; a truncated angular extension on one end of said brick between said pair of flat parallel surfaces; an angular recess on the end opposite said truncated angular extension of said brick between said pair of flat parallel surfaces, said angular recess being designed for receiving said truncated angular extension of an adjacent brick; a top of said brick between said pair of flat parallel surfaces, a first end of said top having a generally conical extension thereabove and a second end having a generally conical recess therein; a bottom of said brick between said pair of flat parallel surfaces, said bottom having a conical recess located immediately below said conical extension on the top of said brick and a conical extension in said bottom immediately below the conical recess in said top of said brick, said conical extensions and conical recesses being designed to fit conical extensions and recesses of adjacent bricks; holes extending from said top of said brick to said bottom thereof, said holes being designed for alignment with holes of adjacent bricks; said truncated angular extension and said angular recess extending from said top to said bottom of said brick an upward extension of one of said pair of flat parallel surfaces above said top and a recess in the other of said pair of flat parallel surfaces below said top, said bottom having substantially identical recesses and extensions for mating with adjacent bricks; and abutting shoulder means between said pair of flat parallel surfaces and both said truncated angular extension and said angular recess.
