Abstract
18,353. Kielberg, C. J. Sept. 11. Moulding cement pipes.-Cement pipes for drains &c. are formed in a mould consisting of a two-part external portion a and an internal core b. The cylinder a is placed on a wooden pallet e, and is locked in position. The cement is then filled into the mould, and the core b turned so as to be worked upwards through the cement by the action of the spiral flanged. A horizontal portion d<1> of the flange smooths off the upper end of the pipe when the core has worked its way to the top. The moulded pipe in the casing a is transferred on the pallet e to the drying-yard, and the casing a is then removed, leaving the pipe to dry on the pallet.
