1,151,173. Articulated pipes; pipe couplings. F. W. SCHWING. 2 May, 1967 [3 May, 1966], No. 30233/67. Headings F2G and F2P. A transportable pipeline structure comprises a platform 6 upon which is mounted a pipeline 1 with its outlet end disposed at a higher level than its inlet end adjacent the platform 6, the pipeline being formed from a plurality of end-toend connected sections 1 each supported in a frame 2, the adjacent ones of which are connected to form a framework for the assembled pipeline sections, at least the outlet portion of the pipe being rotatably mounted relative to the base. As shown, a support 7 for the pipeline 1 is mounted on the platform 6 by a slewable mounting 3 the pipeline being provided with either a rotary joint, not shown, or a flexible portion, not shown, in the region of the mounting 3. Each frame 2 consists of a section of pipeline 1 supported at its ends in a frame 2 by sleeves 14, 14a mounted in transverse members 13, 13a, respectively, the sleeve 14 of one frame entering the sleeve 14a of the adjacent frame below to provide a joint between the pipeline sections of the two frames, and mandrels 16 on the transverse member 13 being received in corresponding apertures 17 in the adjacent transverse member 13a below and being connected by wedges, not shown, driven into slots 18 in the mandrels 16. The pipeline assembly can be raised in the support 7, e.g. by a manually operable winch or by an hydraulic or pneumatic piston and cylinder assembly so that an additional frame can be placed in the support whereupon the assembly of interconnected frames above can be lowered and connected to the additional frame. The winch, or the piston and cylinder assembly, can also be used for removing a pipeline section. The uppermost frame has a projecting pipeline section which is supported by a tie-rod 10 and is counterbalanced by a weight 12, a flexible hose 22 being connected to the outlet of the pipeline section. In a modification, Fig. 2, (not shown), the support (7) is mounted upon a horizontal pivotal axis (8) on the platform (6) of a self-propelled vehicle, the inclination of the assembly being adjustable e.g. by an hydraulic or pneumatic piston and cylinder assembly (5), and only the upper part of the pipeline being slewable at a rotary joint (4). Material, e.g. concrete, can be pumped from a hopper (24) into the pipeline (1) by means of a pump (23). The pivotable axis (8) may be mounted on a slewable joint to which the lower end of the piston and cylinder assembly (5) is connected.
