Abstract: A trolley pole support apparatus is provided in which the trolley pole is urged to an extended position by a spring acting against a moment arm and the force required to position the trolley pole in the stowed position is minimized by minimizing the moment arm between the spring contact point and the trolley pole pivot. By doing so, even with the maximum compression of the spring in the stowed position, this small moment arm permits only small forces to be transmitted to the trolley pole shoe.

Abstract: A trolley pole mechanism for an electric vehicle fitted with an auxiliary power source draws power from overhead lines in a raised position. Its terminal unit comprises two contact heads, sensors responsive to contact with an overhead line, and head guides.

Abstract: An improved technique for regulating the contact pressure of a pantograph brush on an overhead guide conductor is described. The brush is supported for vertical movement in a brush support member for adjustable wiping contact with the overhead conductor. The brush support member is in turn supported for movement in a vertical plane via a two-arm scissors arrangement which is supportable on the roof of an electric vehicle. A high-frequency signal picked up by a transducer situated in the area of the brush and representative of the instantaneous contact pressure of the brush on the wire is compared with an adjustable reference indication indicative of a desired contact pressure, and the resulting difference signal is employed to incrementally adjust the brush contact pressure.
