Vorrichtung mit gelenkig miteinander verbundenen Rohren, zur Verbindung einer ortsfest angeordneten Energiequelle, mit einem im wesentlichen in waagrechter Ebene beweglichen Verbraucher

摘要

A device for conveying fluids or electric current between a stationary source and a mobile consumer, such as one or more motors on the reciprocable carriage of a drawing machine, has a package of elongated sections wherein the upper end of each intermediate section is pivoted to the upper end of one neighboring section and the lower end of each intermediate section is pivoted to the lower end of the other neighboring section. One end of one outer section is connected to the carriage which is reciprocable toward and away from the source along one or more elongated first guide rails tracked by roller followers provided on alternating sections of the package close to the upper ends of such sections. The upper ends of some or all of the sections carry roller followers which track a second guide rail located above the first guide rails and having a downwardly sloping portion close to the source. When the carriage moves toward the source, successive sections are pivoted in the region of the sloping portion to assume substantially vertical positions close to each other. When the carriage is moved away from the source, successive sections are pivoted to move into a substantially horizontal plane and to form an elongated pipeline extending lengthwise of the first guide rails.
