  • Patent number: 7753175
    Abstract: An elevator system (20) includes an underslung car (22). A plurality of load bearing members (32-38) are closer together behind the elevator car and spaced farther apart near a front of the elevator car (22). A plurality of sheaves (40-44) are supported for vertical movement with the car and rotational movement relative to the car (22) such that the load bearing members (32-38) can be arranged in a 2:1 roping ratio and extend underneath the car (22). A disclosed example includes sheaves (40-44) rotatable about sheave axes that are at oblique angles relative to corresponding edges of the elevator car (22).

  • Patent number: 7726459
    Abstract: An escalator step (12) includes a sound barrier material (40) covering over at least a portion of an inner surface (42) of a tread portion(30) and an inner surface (44) of a rise portion (32). In one example, the sound barrier material (40) comprises a sheet of vinyl. The sound barrier material (40) reduces noise radiation from the step (12) toward a cavity (26) within a passenger conveyor support structure (20) and reduces noise emanations from the cavity (26) through the steps (12). Several embodiments for securing the sound barrier material (40) in place are disclosed.
