    A shaft signaling system is meant to enable the on setter to signal to the banks-man. Where there is more than one underground level there must be a means of distinguishing between signals from on setters at the various underground levels. The system also enables the banks-man to signal to each underground level and also to signal to the winding engine-man. In addition to the shaft signaling
