ABSTRACT:
The trolley pole is mounted on a cylindrical bearing member secured to the side of an electric mule or locomotive for pivotal movement about a vertical axis. A latch mechanism provides a segmental plate horizontally disposed acentrically of said cylindrical bearing member for movement with it so as to turn in a horizontal path when the trolley pole and its mounting cylinder are turned, and a latch assembly adjacent said path fixed to a contiguous portion of the locomotive housing having a horizontally pivoted detent that normally rests with its free end within the path of the segmental plate in registration with the latter so as to lock the plate and its associated cylindrical mount and trolley pole in one selected position. The detent is moved about its horizontal axis to displace its free end from the path of the segmental plate to allow the latter to turn with the cylindrical bearing and trolley pole to a second selected position, where the detent again drops into locking position to prevent accidental turning of the trolley pole. A lever mechanism extends across the locomotive from a position accessible to the motorman to the latch assembly to afford remote control of the detent.
