摘要:
A feeder rail construction for rail-type electrification systems comprising an elongate, extruded aluminum support member of good conductivity, having a pair of coextensive spaced-apart parallel longitudinal slots, and an elongate wear-resistant channel member preferably of stainless steel, carried by and coextensive with the support member and characterized by a U-shaped cross section formed by a pair of flange portions and a connecting web portion. The edges of the flange portions are turned back upon themselves so as to present thickened rims. The walls of the slots of the support member have a ribbed configuration constituting irregular surfaces, and the channel member flanges are press-fitted into the slots so as to be permanently retained therein. During the press-fitting operation, the irregular surfaces of the slot walls are sheared or scraped clean, thus exposing a fresh aluminum surface free of oxide which provides improved electrical conductivity between the two members. At least one wall of each support member slot is swaged against the thickened rim of the flange so as to tightly engage the latter and permanently retain the channel member.

A trolley multi-conductor system is disclosed with novel support means wherein each current conductor is rigid and made into sections of predetermined length and two or more such sections are preassembled to form a sub-assembly unit containing at least two parallelly disposed conductor sections of equal length. The two sections are fixed together by two spaced rigid insulating bars, transversely disposed with respect to the conductor sections. The support means includes a plurality of support members disposed in predetermined, spaced apart, overhead positions. Each support member has means to cooperate with respective means on each insulation bar to allow clamping the respective support members and bars together.

A device for mounting a replaceable adaptor rail on a contact rail, the contact rail being provided, along opposed longitudinal sides, with extensions formed to define recesses which open away from the adaptor rail mounting location, the device including two clamping members arranged to be positioned along respectively opposite sides of the adaptor and contact rails and each having an adaptor rail-engaging surface and a hook-shaped arm, a connecting arrangement connected between the members for detachably clamping the adaptor rail between the adaptor railengaging surfaces thereof, two slide members each disposed between a respective clamping member and contact rail and each having a wedge-shaped tongue disposed for engagement in a respective recess, one of the hook-shaped arms being arranged to engage its associated slide member for forcing its associated slide member toward the associated recess, and an adjustment screw associated with the other hook-shaped arm to bear against the slide member associated with such other arm for forcing the associated slide member toward its associated recess.
摘要:
A method of manufacture of a conductor rail consisting of an aluminum body and a layer for instance of steel which method provides a hot union of said materials without obtaining an electrically poorly conducting intermetallic layer.

Electrical distribution and current collecting system for a vehicle traveling on a trackway having a single-track portion and means, such as end loops, for engaging the vehicle forwardly on said portion. A current collecting carriage cooperates with feed conductors disposed along said portion on one side thereof and coupling means arranged on both sides of said vehicle permit electrical and mechanical coupling to said carriage for both directions of traveling of said vehicle.
