  • Electrically driven sheave
    Patent number: 4355785
    Abstract: An electrical drive having a sheave, motor drive shaft, and first and second bearings in coaxial alignment. The first bearing rotatably mounts the sheave on an adaptor member which additionally functions to complete the enclosure of a drive motor module removably attached thereto. The second bearing, which is part of the drive motor module, supports one end of the motor drive shaft, while the other end extends through an opening in the adaptor module into driving engagement with, and support by the sheave.

  • Elevator system with fish plate for correcting an out-of-tolerance between guide dimension
    Patent number: 4079817
    Abstract: An elevator system including an elevator car and two horizontally spaced, vertically oriented, guide rail assemblies for guiding the elevator car. Each guide rail assembly includes a plurality of vertically aligned guide rail members, the adjacent ends of which are interconnected via fish plates.

  • Elevator system
    Patent number: 4011928
    Abstract: An elevator system including a transmitter-receiver arrangement for detecting mechanical damage to the elevator system, such as might be caused by an earthquake. A transmitter carried by the counterweight provides a signal for a remotely located receiver, as long as the counterweight moves within its normal vertical path. Movement of the counterweight outside of this path terminates the transmitter signal and a control device operated by the receiver modifies the operation of the elevator system.
