This device is called a "Tramp". It allows one telegraph or telephone line to cross over another line. It helps to reduce electromagnetic distortion to a signal being sent over the wire.

The technical term for the process is "Transpositioning". The reasons for doing this can be found at www.the-electric-orphanage.org/transpositioning/.
