| 摘要 | 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. | ||||||
| 权利要求 | 1. A sliding collector device for electrification systems comprising, in combination: a. a pair of contact shoes disposed alongside each other and adapted to slide along a conductor bar, b. each of said shoes having a pair of electrically conductive contact surfaces, c. the contact surfaces of one shoe facing generally in different directions from the contact surfaces of the adjoining shoe and the surfaces of the shoes being arranged for engagement respectively with opposed cooperable surfaces on each of a pair of spaced, coextensive conductor bar, d. said shoes each having a pair of opposite side surfaces between which the contact surfaces of the shoes extend, e. said shoes being arranged one upstream of the other with a side surface of one shoe adjacent and facing a side surface of the other shoe, f. spring means mounting said shoes for limited relative movement in opposite directions, g. said means being capable of biasing said shoes in the said opposite directions when the shoes are in given operative positions, thereby to bias the contact surfaces thereof for pressing engagement with the cooperable surfaces of the spaced bars. 2. A sliding collector device as in claim 1, wherein: a. the contact surfaces of each of said shoes are angularly disposed with respect to each other, b. said surfaces being in the configuration of a V-trough, 3. A sliding collector device as in claim 1, wherein: a. the contact surfaces of each of said shoes are angularly disposed with respect to each other, b. said surfaces comprising a crowned configuration. 4. A collector as in claim 1, wherein: a. the contact shoes are superposed and arranged back to back. 5. A collector as in claim 1, wherein: a. there are additional shoes similar to the shoes defined, b. all of said contact shoes being disposed in a row and the pairs of contact surfaces of the shoes being arranged in staggered relation with respect to each other. 6. A collector as in claim 1, wherein: a. the contact shoes comprise blocks of metallic composition, having body portions provided with recesses in their sides, b. said spring means comprising sheet metal plates having fastener portions to which the shoe body portions are secured, c. said fastener portions including lugs disposed in the recesses of the body portions. 7. A collector as in claim 6, wherein: a. the sheet metal plates are arranged in spaced, parallel relation and have offset mounting portions engaged with and secured to each other. 8. A collector as in claim 6, wherein: a. the sheet metal plates are arranged in spaced parallel relation and have angularly extended base portions, and b. a spring clip engaged with the base portions of the metal plates for mounting the latter and biasing the same, thereby to urge the contact shoes in directions away from each other. 9. A collector as in claim 8, wherein: a. the recesses in the shoe blocks comprise blind holes, b. said lugs of the fastener portions extending angularly with respect to the metal plates and being disposed in said blind holes. 10. A collector as in claim 1, wherein: a. the contact shoes comprise blocks of metallic composition, having shank portions provided with bearing grooves, b. said shoes being disposed in staggered relation with the shank portions in alignment, c. a pintle extending along the bearing grooves of the shanks, d. said spring means comprising a slitted spring metal tube enclosing the pintle and having the longitudinal edges of the slit thereof engaged with the shoe shanks to impart bias to the shoes. 11. A collector as in claim 10, and further including: a. pull links carried by the ends of the pintle and adapted for attachment to pull cords for the purpose of propelling the collector along a conducting rail structure. 12. A collector as in claim 1, wherein: a. tHe contact shoes comprise blocks of metallic composition, b. said spring means comprising sheet metal plates having fastener portions to which the shoe body portions are secured, c. said metal plates being arranged in spaced, parallel relation and having offset mounting portions engaged with and secured to each other, d. each of said mounting portions having a folded lug engaging the other mounting portion to secure the portions together, and e. a locking bolt passing through the mounting portions. 13. A collector device as in claim 1, wherein: a. the contact shoes and spring means are constituted of a single piece of spring sheet metal and are integral with each other. 14. A collector as in claim 13, wherein: a. the contact shoes are superposed and arranged back to back, b. said sheet metal comprising a U-shaped body portion. 15. A collector as in claim 13, wherein: a. the contact shoes are staggered and disposed in a row, b. said sheet metal comprising a flat body portion. 16. A sliding collector device as in claim 1, wherein: a. said spring mounting means comprises parallel studs and a base on which the studs are carried, b. one of said contact shoes being slidably carried by said studs, c. said spring means including a coil spring engaging said one contact shoe. 17. A sliding collector device as in claim 1, wherein: a. the contact shoes are urged toward each other by said spring mounting means. 18. A sliding collector device as in claim 1, wherein: a. the contact shoes are urged in directions away from each other by said spring mounting means. 19. A sliding collector device for electrification systems comprising, in combination: a. a plurality of contact shoes disposed adjacent each other, b. each of said shoes having electrically conductive contact surfaces adapted to slide along a conductor bar, c. said contact surfaces facing in different directions for engagement with a pair of spaced, opposed coextensive conductor bars, and d. spring means mounting said shoes for limited relative movement in opposite directions, e. said means being capable of biasing said shoes in the said opposite directions when the shoes are in given operative positions, thereby to bias the contact surfaces for pressing engagement with the cooperable spaced bars, f. said contact shoes comprising blocks of metallic composition, having supporting shank portions, g. said spring means comprising sheet metal having a plurality of arms extending in parallel directions, h. said arms having bent, angularly extending slotted extremities disposed in a row, i. the shank portions of the contact shoes extending through the slots of the arm extremities and being secured to said arms. 20. A collector as in claim 19, wherein: a. the arms of the sheet metal member and shank portions of the shoes are apertured and secured together by headed fasteners. 21. A collector as in claim 19, wherein: a. the sheet metal spring means comprises a channel member having flange portions from which the arms extend. 22. A collector as in claim 19, wherein: a. the shank portions of the shoes have enlarged ends preventing their withdrawal from the slotted extremities of the arms, b. said arms having openings communicating with and larger than the slots thereof, c. the enlarged ends of the shanks being receivable in the arm openings to enable insertion and removal of the shanks respectively in and from said arm extremities. |
