    • The contact pole of a trolley bus carries at its normally upper end a trolley shoe and an upwardly projecting guide which may jointly pivot on the pole about an approximately vertical axis. When the pole is partly raised by a heavy spring and swung horizontally, the trolley shoe is vertically aligned with an overhead wire when the guide abuts against the wire. When the pole is further raised by the spring, the trolley shoe engages the wire, and the guide is automatically dropped below the trolley shoe so as not to collide with hangers for the overhead wire. When the pole is lowered by an operating mechanism against the biasing force of the spring, a motor-driven element of the mechanism connected to the guide by a motion transmitting train automatically returns the guide to its position above the trolley shoe.
    • 无轨电车的接触极杆在其正常的上端承载有滑轮和向上突出的导向器,其可以围绕大致垂直的轴线在杆上共同枢转。 当极杆被重弹簧部分地升起并水平摆动时,当导向件抵靠电线时,滑车靴与架空线垂直对齐。 当杆被弹簧进一步升高时,滑车鞋与线接合,并且引导件自动地落在滑车滑架下方,以免与架空线的吊架碰撞。 当通过操作机构抵抗弹簧的偏压力使杆下降时,通过运动传动系连接到引导件的机构的电机驱动元件自动将引导件返回到其在滑轮上方的位置。
