  • Elevator governor
    Patent number: 6988593
    Abstract: A centrifugally activated device for controlling the speed of movement of an elevator cab includes the capability of controlling upward and downward movement. A first stopping device is associated with at least one elevator sheave. A second stopping device preferably is supported on an opposite side of the same sheave. The second stopping device preferably includes centrifugally activated components such as a latch member that moves from a first position into a second, stopping position responsive to an undesirably high speed of upward movement of the elevator cab. The centrifugally activated components preferably include a latch member that is rotatably supported on the sheave and has an engaging member at one end that engages a cooperating stop surface near the sheave to prevent the sheave from further rotation upon the sheave reaching an undesirably high rate of rotation.
    Type: Grant
