  • 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.
  • a duct S supported, for example, by a rod 56; the duct 55 has as its free end an end-piece 29.
  • a ram 57 is incorporated and is connected between the tank 50 and the frame 52 supporting the tank.
  • the displacement of the plant 49 on the track, the displacement of the frame 52 on the frame 53, the angular displacement of the tank 50, are carried out by an operative 58 positioned on an appropriate platform 59, and a second operative 60 ⁇ is positioned between the moulds on a platform 61.
  • the operative 58 actuates the displacement of the plant 49 on the rails in such manner that the end of the duct 55 is brought into alignment with a selected valve V, then, by action on the ram 57, actuates the angular displacement of the tank 50 in such manner as to bring the end-piece 29 into the immediate vicinity of the valve V, after which the ram 16 associated with the valve V is brought into action by the second operative 60 which causes the opening of the slide valve 11; the locking levers 26, 27 are displaced by the slide valve during opening, are brought into contact with the journals 37, 38, and the edges 28 draw the end piece 29 against the lower face of the mounting of the valve and then lock the valve for as long as the slide valve 11 is in the open position (FIG. 2).
