Magnetic linking mechanism for measuring instruments

Claim 1

IN A MEASURING INSTRUMENT OR THE LIKE HAVING INDICATING MEANS THEREON FOR MEASURING A MOVEMENT OF A DETECTOR MEMBER, THE IMPROVEMENT WHICH COMPRISES A PARAMAGNETIC ARM MOUNTED ON THE DETECTOR MEMBER IN POSITION TO SWING THROUGH AN ARC IN RESPONSE TO MOVEMENT OF THE DETECTOR MEMBER, A LINKING MEMBER PIVOTALLY MOUNTED WITH ONE END SWINGABLE THROUGH AN ARC IN PROXIMITY TO SAID PARAMAGNETIC ARM AND THE OTHER END CONCURRENTLY SWINGABLE THROUGH AN ARC, EACH OF SAID ENDS OF SAID LINKING MEMBER BEING BIFURCATED AND MAGNETIZABLE THEREBY FORMING AN EFFECTIVE HORSESHOE MAGNET AT EACH END, THE END OF SAID LINKING MEMBER IN PROXIMITY TO SAID PARAMAGNETIC ARM STRADDLING SAID PARAMAGNETIC ARM AND SPACED THEREFORM WHEREBY MOVEMENT OF SAID ARM CAUSES MOVEMENT OF SAID LINKING MEMBER, A DIAMAGNETIC INDICATING SUPPORT PIVOTALLY MOUNTED ADJACENT TO AND STRADDLED BY THE OTHER BIFURCATED END OF SAID LINKING MEMBER AND MAINTAINED IN SPACED RELATIOIN, AND A SMALL PARAMAGNETIC BODY MOUNTED IN SAID DIAMAGNETIC SUPPORT IN POSITION TO COMPLETE A MAGNETIC LINKAGE BETWEEN THE TWO MEMBERS WHEREBY MOVEMENT OF SAID LINKING MEMBER MOVES SAID INDICATING SUPPORT.
