Concrete ties
Abstract
Abstract A CONCRETE TIE IS PROVIDED WITH PROTUBERANCES ON OPPOSITE SIDES THEREOF SERVING TO ANCHOR A PAIR OF ONE-PIECE SPRING-TYPE RAIL FASTENERS. EACH FASTERNER HAS A BIGHT TENSIONED ON THE PROTUBERANVE, AND A PAIR OF LEGS EXTEND UPWARD FROM THE BIGHT. THE UPPER ENDS OF THE LEGS ARE BENT TO AFFORD EXTENSIONS WHICH OVERLIE THE BASE OF THE RAIL, AND BENDS THEREIN ENGAGE THE BASE OF THE RAIL WITH A SPRING FORCE. THE FREE ENDS OF THE FASTENERS END IN HOOKS, ONE HOOK BEING THE COMPLEMENT OF THE OTHER SO THAT A PAIR OF SUCH FASTENERS MAY BE COMPLEMENTALLY JOINTED AT THE FREE ENDS AND TENSIONED ONE ON THE OTHER. THE PROTUBERANCES OF THE TIE ARE UNDER A GREAT DEAL OF COMPRESSION AND ARE REINFORCED BY BENDS IN A PLURALITY OF ROD-LIKE STRINGERS EMBEDDED IN THE TIE TO EXTEND BETWEEN THE PROTUBERANCES.
