Balancing machine

Claim 1

A DEVICE FOR MEASURING THE UNBALANCE OF A REVOLVING BODY IN TWO REFERENCE PLANES COMPRISING A MACHINE FRAME, TWO MUTUALLY DISPLACEABLE BEARINGS FOR THE SHAFT OF THE REVOLVING BODY ARRANGED ON SAID MACHINE FRAME, OSCILLATION PICKUPS CONNECTED WITH EACH OF SAID BEARINGS FOR PRODUCING ELECTRICAL VOLTAGES PROPORTIONAL TO THE BEARING FORCES, A VOLTAGE DIVIDER CONNECTED WITH EACH OF SAID PICKUPS, SAID VOLTAGE DIVIDERS HAVING A FIXED MID-TAP AND A VARIABLE SLIDER MEMBER, A CIRCUIT CONNECTING SAID RESPECTIVE SLIDER MEMBERS AND RESPECTIVE MID-TAPS TO EACH OTHER A VARIABLE IMPEDANCE MEANS CONNECTED INTO SAID CIRCUIT IN SERIES WITH THE TAPS AND SLIDER MEMBERS, SAID VOLTAGE DIVIDERS BEING MOUNTED ON ONE OF SAID BEARINGS, AND HAVING A RESISTOR MEMBER UPON WHICH SAID MID-TAP IS FIXED AND RELATIVE TO WHICH SAID SLIDER MEMBER IS VARIABLE ON EACH SIDE OF SAID TAP, SAID MEMBERS ON ONE DIVIDER BOTH BEING MOVABLE RELATIVE TO SAID ONE BEARING, ONE OF SAID MEMBERS ON THE OTHER DIVIDER BEING MOVABLE RELATIVE TO THE ONE BEARING, MECHANICAL COUPLING MEANS ENGAGING ONE MEMBER ON ONE DIVIDER TO SAID IMPEDANCE MEANS AND ENGAGING ANOTHER OF SAID MEMBERS TO THE OTHER BEARING FOR CHANGING THE RESISTANCE OF SAID VOLTAGE DIVIDER AND SAID VARIABLE IMPEDANCE MEANS IN ACCORDAMCE WITH ANY CHANGE IN MUTUAL SPACING OF SAID BEARINGS, AND SETTING MEANS FOR ADJUSTING SAID VOLTAGE DIVIDERS ACCORDING TO THE RELATIVE POSITION OF ONE OF SAID BEARINGS TO ONE OF SAID PLANES, AND MEANS FOR MEASURING THE UNBALANCE OF THE REVOLVING BODY IN THE OTHER REFERENCE PLANE.

Claim 2

A DEVICE FOR MEASURING THE UNBALANCE OF A REVOLVING BODY IN TWO REFERENCE PLANES COMPRISING A MACHINE FRAME, TWO MUTUALLY DISPLACEABLE BEARINGS FOR THE SHAFT OF THE REVOLVING BODY ARRANGED ON SAID MACHINE FRAME, OSCILLATION PICKUPS CONNECTED WITH EACH OF SAID BEARINGS FOR PRODUCING ELECTRICAL VOLTAGES PROPORTIONAL TO THE BEARING FORCES, A VOLTAGE DIVIDER CONNECTED WITH EACH OF SAID PICKUPS, SAID VOLTAGE DIVIDERS HAVING A FIXED MID-TAP AND A VARIABLE SLIDER MEMBER, A CIRCUIT CONNECTING SAID RESPECTIVE SLIDER MEMBERS AND RESPECTIVE MID-TAPS TO EACH OTHER A VARIABLE IMPEDANCE MEANS CONNECTED INTO SAID CIRCUIT IN SERIES WITH THE TAPS AND SLIDER MEMBERS, SAID VOLTAGE DIVIDERS BEING MOUNTED ON ONE OF SAID BEARINGS, AND HAVING A RESISTOR MEMBER UPON WHICH SAID MID-TAP IS FIXED AND RELATIVE TO WHICH SAID SLIDER MEMBER IS VARIABLE ON EACH SIDE OF SAID TAP, SAID MEMBERS ON ONE DIVIDER BOTH BEING MOVABLE RELATIVE TO SAID ONE BEARING, ONE OF SAID MEMBERS ON THE OTHER DIVIDER BEING MOVABLE RELATIVE TO THE ONE BEARING, MECHANICAL COUPLING MEANS ENGAGING ONE MEMBER ON ONE DIVIDER TO SAID IMPEDANCE MEANS AND ENGAGING ANOTHER OF SAID MEMBERS TO THE OTHER BEARING FOR CHANGING THE RESISTANCE OF SAID VOLTAGE DIVIDER AND SAID VARIABLE IMPEDANCE MEANS IN ACCORDAMCE WITH ANY CHANGE IN MUTUAL SPACING OF SAID BEARINGS, AND SETTING MEANS FOR ADJUSTING SAID VOLTAGE DIVIDERS ACCORDING TO THE RELATIVE POSITION OF ONE OF SAID BEARINGS TO ONE OF SAID PLANES, AND MEANS FOR MEASURING THE UNBALANCE OF THE REVOLVING BODY IN THE OTHER REFERENCE PLANE.
