Blocking machines' history The modern concrete block manufacturing industry is not the result of a gradual evolution but was abruptly driven by the invention of a machine with adjustable removable moulds capable of producing solid blocks. Solid concrete blocks were first employed in 1832 by the builder William Ranger in England, who patented his version of "Ranger's Artificial Stone".
