Abstract
An indicator device for a piston and cylinder assembly has an indicator pin with a distal end indicator section for extending out of a side wall of a piston cylinder assembly when the piston and rod assembly is not at the end of its return stroke. A retracting device retracts the indicator pin when the piston and rod assembly moves to the end of its return stroke and has an optional internal lock that mechanically axially affixes the piston and rod assembly.
