  • Patent number: 5366044
    Abstract: A magnet 34 is mounted to a linkage 30 which passes vertically over a conductive vane 32 which extends the entire length of the elevator hoistway 46. Eddy currents induced in the conductive vane 32 as the magnet 34 passes over the conductive vane 32 cause a reaction force on the magnet 34 and the linkage 30. The reaction force causes the safety 26 or 28 to contact a guide rail 22 on which an elevator car 10 is riding, thereby braking the elevator car 10 at any point in the hoistway between the terminals and eliminating the need for a governor. The vane width 50 is large at the terminals as compared to the middle of the hoistway 46 which increases the reaction force at the terminals. The invention eliminates the need for a governor.
