  • crank arms 19, 20 are connected to the slide valve by a spindle 24 engaged in slots 25 extending lengthwise of the crank arms.
  • the sleeve 21 is provided, for example by welding, with locking levers 26, 27, eachl arranged so that one edge 28 thereof can co-operate with an end-piece indicated generally at 29.
  • Each cheek plate 30, 31 is welded to the lower 3 face of the mounting 10 and form guides (FIGS. 2 and 4) for the end-piece 29.
  • Each cheek plate 30, 31 has a downwardly tapered internal plane face 32, FIGS. 2 and 4, and ramps 33, 34 (FIG. 2) forming an inverted V-shaped free lower edge 35 for each guide.
  • the end-piece 29, at the end thereof which engages the mounting 10 has an orifice of appropriate cross Section and is arranged to be in contact with the mount ing and is sealed thereto by a joint 36, FIG. 4.
  • the end-piece At a distance from its free extremity, the end-piece has two radial journals 37, 38 which are diametrically opposed and rigidly secured to the end-piece by welds, and reinforcing rings 39, FIG. 4.
  • a valve of this kind is suitable for use in lling vertical moulds as shown in FIG. 5, these moulds in manner know per se comprising two vertical spaced-apart faces 40, 41 resting on a fixed frame 42 in alignment with displaceable elements 43, 44 which are disposed to move on end beams and are actuated by rams (not shown).
  • the base of e'ach of the moulds has one or more valves V as hereinabove described, symmetrically disposed at either side of a vertical axis A-A and in alignment with openings 45, FIGS. 2 to 4, in the bottom 46 of the moulds.
  • the valves are each secured to the bottom of the mould by their mountings 10 by screws 47, FIGS. 1 and 4, in a manner such that no part of the mounting projects inside the mould, see FIGS. 2 to 4.
  • moulds are advantageously disposed one beside the other and a concrete feeding plant 49 is displaceable on a conventional track in alignment with the moulds, the plant comprising a concrete tank 50, FIG. 5, pivotally arranged at 51 on a frame 52 itself displaceable in the direction of the arrow F on a second frame 53 resting on the track.
