Log for constructing log structures and associated log fabricating process

An improved log for interlocking with other logs for constructing log structures, said improved log comprising:

• an elongated body having an exterior surface, said body defining a longitudinal axis and having first and second opposite end portions, a top portion and a bottom portion, said body being provided with a laterally disposed downwardly oriented saddle notch proximate at least one of said end portions for closely receiving a top portion of another said improved log, said saddle notch defining an inner notch surface conforming to an exterior surface of said top portion of another said improved log, said notch surface carrying a pair of longitudinally oriented tongues projecting into said saddle notch, said body being further provided with a pair of laterally oriented grooves provided in said exterior surface of said top portion and disposed above said saddle notch of a depth sufficient for closely receiving tongues in a saddle notch of another said improved log;
• and
• a pair of longitudinally oriented further tongues disposed on said top portion of said body and extending substantially the length of said body, and said body is provided with a pair of longitudinally oriented further grooves disposed in and extending substantially the length of said bottom portion of said body for closely receiving said further tongues of another improved log.

A process for fabricating a log for interlocking with other logs for construction of log structures, said log having an elongated body defining a longitudinal axis and having first and second end portions, a top portion and a bottom portion, said process comprising the steps of:

• cutting into said bottom portion of said body a lateral downwardly oriented saddle notch proximate at least one of said end portions for closely receiving said top portion of said body of another said improved log, said saddle notch defining an interior notch surface carrying at least one longitudinally oriented tongue projecting into said saddle notch from said notch surface;
• and
• cutting into said exterior surface of said top portion of said body above said saddle notch at least one laterally oriented groove of a depth sufficient for closely receiving a tongue within a saddle notch of another said improved log.
