  • Locomotive air compressor with an electric motor supported by an external bearing
    Patent number: 6659739
    Abstract: The present invention provides an externally mounted assembly for supporting a rotatable shaft member driven by an electric motor. The externally mounted assembly comprises an annularly projected bearing support member disposed on a substantially vertical plane and a bearing member mounted on the bearing support member. Such bearing member is connectable with the rotatable shaft member for supporting such rotatable shaft member thereby reducing extraneous vertical and horizontal movement of such rotatable shaft member while permitting such rotatable shaft member to rotate freely.
