Such counterweights are normally used for semaphore signals to put the signal to danger in case the wire breaks but this seems to be a temperature compensator and keeps the wires in proper tension.

This is just to keep the wires for semaphore signalling in proper tension. The counterweight for semaphore arm to put the signal in danger in case of wire break is a part of semaphore only.
