    摘要: A railroad spike of generally conventional form provided with a spur which, in the unused position, extends downwardly from the head of the spike parallel with and closely adjacent to the shank of the spike. When the spike is driven in the usual manner, straight down into a wood railroad tie, the spur is diverted away from the shank of the spike due to the cam action which takes place as a result of the beveled form of the remote end of the spur.
