Spring loaded thermocouple unit and mounting cap therefor

摘要: There is combined with a thermocouple unit, having coil spring encircling and mounted on at least the front end portion thereof so can be compressed forwardly while of unit pressed against inner wall bore, mounting cap longitudinally extending passageway. The has means for attaching same outer bore retractable abutment which most advantageously an inwardly resiliently urged member laterally across part passageway connecting lift handle outside raised to retract permit quickly easily moved within maintaining under compression. Release establishes upon release frictionally engages inhibit relative rotational movement between unit.
