Abstract
341,122. Centrifugally casting concrete pipes. KUROYANAGI, S., 1, Nishi- Qchome, Kitasanjo, Sapporo, Japan. Oct. 15, 1929, No. 31341. [Class 87 (ii).] Concrete pipes are moulded in a centrifugal moulding machine comprising a mould 23 mounted at one end on a driving bracket 11 and secured at the other end to a ring 22 running in a support constituted by three adjustable rollers 21, 14. A saddle 36 running on a bed 35 as controlled by a handwheel 37 carries a frame comprising a bar 42, Fig 8, and rigid supports 50, 51 in which is mounted a shaft 45 carrying a scraper 53 and a roll 52, Fig. 9, for smoothing the interior of the pipe. The scraper and roll are adjusted by rotating the shaft 45 by worm gearing and a handwheel 48. The scraper may be formed with a projection 71 to form a socket at one end of the pipe and a roller 70 of correspondingly greater diameter may be mounted on the roll 52. When no socket end is required, enlarged rollers are used at each end of the roll 52 in order to compress the mouth portions of the pipe before scraping. A splash guard 67 is formed in two parts, hinged on a bar 57, to enclose the driving end of the mould, and is automatically opened and closed by a cord 62 controlled by the movements of the saddle 36. Reinforcement bars may be placed in the mould for the production of reinforced pipes.
