Abstract: 683,097. Machines for casting concrete pipes. LIVINGSTON CONSTRUCTION CO., Ltd. Dec. 6, 1950, No. 29876/50. Class 87 (ii). A concrete pipe is moulded in the annular space between a vibratory core 4, e.g. of the kind described in Specification 683,098, [Group XXIV], and an outer mould 5, the finished pipe being ejected upwardly by first stripping the moulded pipe and mould 5 upwardly off the core and then withdrawing the mould 5 downwardly from the pipe. A pivoted cover 20 is carried by a spindle 27 and can be rotated by hand whilst the concrete is being compressed. The bottom of the mould space is closed by a sleeve 18 whose lower flange 19 rests loosely on an annular platform 11 suspended, by means of rods 10, from the bottom flanges of the outer mould 5. After the moulding operation, handle 30 is actuated to raise, through links 12, 14, the outer mould 5 together with the sleeve 18, thus stripping the pipe from the core 4. When the upper limit of this movement is reached, the flange 12 of the sleeve 18 engages a catch 31 on a spring-biassed lever 32. When the lever 30 is returned to its original position the outer mould 5 moves downward leaving the sleeve 18 retained in the upper position by the catch 31. The moulded pipe is then free to be removed. The sleeve 8 is released and allowed to fall to its original position by actuation of the lever 32. The vibrator is driven by a motor 42 and is controlled in the manner described in the Specification referred to above by means of a treadle 52.
