Abstract
288,377. Hume, W. R., and Hume Steel, Ltd. Jan. 10, 1927. Centrifugal machines; moulding pipes.-A cement pipe with a metal faucet 4 permanently secured to its outer circumference so as to project beyond the end is formed centrifugally by securing the faucet liquid tight within the flared end 3 of a centrifugal mould by means of a rubber ring 18 and arranging part of the inner surface of the faucet to be covered by a portion 21 of a flanged rubber wheel 12 by means of which the mould is rotated so that the cement is clear of the outer end of the pipe. Reinforcement 17 of the cage type may be embedded in the cement, the ends being welded to or otherwise engaged with the faucets 4. The portion 21 of the runner wheel 12 may be replaced by a rubber &c. ring. The meeting edges 8 of the mould are secured by means of studs 9 and wedge plates 11 and a strip of rubber &c. is interposed between the edges to prevent moisture or cement escaping.
