Abstract: 661,290. Moulding concrete pipes. GOWING. N. E., NORMAN, J. W. E., and NORCON. Ltd. May 11, 1949 [Dec. 24, 1948], No. 33287/48. Class 87(ii) The subject-matter of this Specification is substantially the same as that described in Specification 661,289 by the same applicant, in so far that Figs. 1-4 of this Specification are included within the drawing of Specification 661,289. In the present Specification table 45 and the socket former 89, Fig. 6, are modified, and vertically upstanding bars 86a, Figs. 3, mounted on the piston crown are adapted to form the concrete material into a substantially cylindrical wall and feed this wall, as the piston rotates and moves upwardly, into the space defined between the upper end of the mould 93 and the outer surface of the former. The mould is mounted so that its upper end projects above the vertically adjustable tray 45. The socket former 89 has a flange 90 for securing to the plate 47, the inner diameter of the former 89 being such that the piston with the packing blades 63 in the open position can pass therethrough. The underside of the flange 90 has wedge like packers 95, and holes or slits may be provided through the flange to allow the escape of excess concrete. The former 89 produces a stepped, preferably tapering, socket end, and small steps or grooves may also be provided to allow for packing material. The male end of the pipe at the bottom of the mould may be complementary to the socket. A detachable annulus 92 secured to the tray 45 receives the upper end of mould 93 and bears on a right angle section 94 on the outside of the mould. In operation, the apparatus is set up as in the prior Specification, the piston lifted vertically and at the same time rotated. Concrete material is fed on to the piston crown and is built up into an advancing wall to enter the socket space. the table 45 being rotated in a direction contrary to the direction of rotation of the piston so that the packers 95 in combination with the piston consolidate the concrete in the space. The table is then stopped, the blades 63 retracted, and the still rotating piston returned to the bottom of the mould to smooth the pipe bore.
