  • Tracer head
    Patent number: 4177567
    Abstract: This disclosure relates to a novel tracer head comprising a stylus, stylus support and housing, and two perpendicular differential transformers. The stylus has a unique configuration enabling more precise memory of its null position when the stylus is not deflected. Further, the stylus has a rotating top pin for contacting the pattern or template that assures a condition assumed in tracer control systems but not achieved under all conditions, i.e., the stylus will deflect away from the template normal to the template edge.
