| 161 | Rail-type electrification system | US3649779D | 1970-04-17 | US3649779A | 1972-03-14 | HOWELL ALLEYNE C JR |
| A rail-type electrification system comprising one or more rail members each of which is constituted of a pair of coextensive spaced, opposed, conductor bars defining between them a path of travel for a contact shoe or collector assemblage. Each collector assemblage comprises a plurality of shoes disposed between the bars and adjacent each other, each of said shoes having angularly disposed contact surfaces which face away from each other. A spring clip carries the contact shoes and permits limited relative movement while biasing them against the bars. The shoes and spring mounting can be connected by cables to equipment. Each pair of shoes has a total of four contacting faces bearing against the two bars of the rail member.

| A current supply arrangement for a mobile load device consists of an elongate, flexible, stringlike member of hollow-sectioned profile forming a collection line duct accommodating a flexible conductor of corresponding length and forming a single current supply pole, and a current pickup device comprising a slide carried by the collector line duct and guided in a slot therein, the slide being connected with the load device for traction thereby. A plurality of these single current supply poles are strung in side-by-side parallel relation along a required route to form a multipole current supply unit.
