ABSTRACT:
A multi-dial, manually operable indicator employing color-coded, alphabetical and numerical indicia which are indicative of railway or road vehicle destinations, regardless of whether they may be local or outbound, major or minor vehicle defects requiring repair, other varied information requiring matching of indicia for proper vehicle selection, and other indicia affording useful information to the driver of the associated vehicle or highway or railway personnel. A novel clutch mechanism which is effective under the control of a single knob affords selective dial rotation while other manually operable knobs effect pointer operations indicative of the condition of special vehicle equipment such as refrigeration apparatus or the like.
