Abstract: A sliding contact for collecting current from a two-rail track system of a toy railroad to a toy train, has a holding plate, two contact pins mountable on the toy train by the holding plate and arranged to be located above the rails, and a sliding bridge which engages with the contact pins so as to allow lateral movement between the latter and the former, and is arranged to slide along both rails of the track system and to maintain electrical connection between the rails and the contact pins. The sliding bridge may be provided with guiding elements for guiding the sliding bridge during its sliding along the rails.
Abstract: Two shiftable bus bar unit point sections are simultaneously shifted to allow one of the sections to align with a stationary bus bar unit point section. A coupler slides on the stationary point section toward the just aligned one of the shiftable point sections to couple the same with the stationary point section. The shifting of the shiftable point sections and the sliding of the coupler are controlled by an operating mechanism which employs a cam. A holding device covers sealingly the electrically dangerous exposed end of the other of the shiftable point sections.
Abstract: A current collection system for a travelling body comprising main rigid trolley rails continuously arranged one after another in the direction of the track of the travelling body; an auxiliary rigid trolley rail which is arranged between the confronting ends of the adjacent main rigid trolley rails and which has one end thereof supported at a fixed support point and the other end thereof supported at a movable support point; a pair of contactor-carrying plates which are attached to the travelling body and are arranged to have said main and auxiliary rigid trolley rails held between the pair of the plates; and two pairs of contactors which are arranged to press each of the main and auxiliary trolley rails on both sides thereof separately from each other. These pairs of contactors are arranged to come into contact alternately with the main and auxiliary rigid trolley rails while the travelling body is on the move.
Abstract: Three phase power feeding device for a track guided vehicle including three power feeding lines provided along one side of the track, the center one of the feed lines being located closer to the track than the other two of the lines. The vehicle is provided with a collector device comprised of three collector shoes adapted to be engaged respectively with the power feed lines. The collector shoes are associated with insulative shoes which are longer than the collector shoes so that the insulative shoes are maintained in contact with the respective ones of the power feed lines even when the collector shoes are detached from the feed lines due to rolling movement of the vehicle.
Abstract: A power collection apparatus is disclosed for the purpose of power distribution from a central power supply to the propulsion motors of at least one mass transit vehicle operative with a predetermined roadway track, including one or more rail gaps and/or crossover switches, to permit the vehicle to transfer from one section to a second section of that roadway track. The power collection apparatus includes collector support apparatus carried by each vehicle and designed to be operative with a rail support member for three individual phase power rails, a ground rail and a signal rail, permitting high speed vehicle passage through a rail gap and a crossover switch.

Abstract: A rail electrification system for electric railways utilizing 3-phase power, comprising three conductor rails arranged in a group characterized by a staggered relationship, commonly known as a delta configuration, so that two of the rails face in one direction and the third faces in an opposite direction. For taking off the 3-phase power from the conductor rails, the car is equipped with two sets of three collectors or shoes each, with the sets being disposed on opposite sides of the conductor rail group. Three of the collectors (not all in one set) function when the car is traveling in one direction along the rails, whereas the remaining three collectors function when the car has been turned around and is traveling in the opposite direction along the rails.
Abstract: A current collector shoe suspension for sliding contact with an electric power line in an externally powered electric vehicle. Current collecting shoes are resiliently biased toward a power rail through a plurality of interconnected vibration absorbing units pivotally mounted to the vehicle. Each unit can vibrate independently of the others, and the units have different resonance points so displaced that their vibration characteristic curves overlap, whereby the shoes maintain contact with the rail over a wide range of vibration frequencies and amplitudes.

Abstract: Manual closure of a switch in a power-supply circuit to an explosive type bolt causes detonation of the bolt which releases a caged spring that thereupon is rendered effective to rock a lever in the direction to lift a current-collecting shoe out of engagement with the surface of a power-supply third rail thereby causing power knockout to the driving motors of an electrically propelled vehicle.
Abstract: The wear pad of a third rail shoe for an electric railway car has the electrode opening therein so configured as to tip the electrode substantially to the attitude of the overhead cable attached to the electrode.
