  • the tube 51 slides vertically in a guide means, for example in an outer tube 53 of larger diameter.
  • the tube 51 has fins 54 which are engaged in vertical slots 55 cut in the tube 53.
  • the fins 54 prevent the tube 51 from rotating on its axis and the ends of the slots 55 serve as upper and lower stops which limit the travel of the inner tube.
  • the height of the slots 55 is slightly greater than the difference in height between the highest and the smallest of the containers 6 that can be used.
  • tube 53 could be replaced by any other guide means, for example by vertical rods.
  • a spring 56 is placed in the space between the inner tube and the outer tube.
  • a handle 57 fixed to the external tube makes it possible to manually hold it in the low position where the end of the tube is engaged in the neck of a container 6, as shown in FIG. 1.
  • the spring 56 When the handle is released, the spring 56 returns the internal tube to its rest position which is the high position.
  • the spring 56 can be replaced by equivalent means, for example the tube 51 can be suspended from a spring which is stretched when the tuge 51 is lowered. It can be suspended from a counterweight.
  • the hose 52 can be wound on a spring reel which tends to rewind it when it is unwound and which returns the tube 51 to the high rest position.
  • a limit switch 58 detects the high rest position of the internal tube 51. This switch fulfills certain functions of the switch 17 in FIG. 3. It prohibits the opening of the solenoid valve 43 at the start of a cycle. It also controls the printer and the reset of the counting unit when printing is complete, if it is activated during a cycle before level sensor 44.
  • the lower end of the tube 51 comprises a detector for the presence of the container 6, which is shown on a larger scale in FIG. 7.
  • This detector has a ring 59 which slides outside the tube 51 between two flanges or stop rings 60 and 61.
  • the upper flange 60 carries a microswitch 62 the contact of which is closed by the sliding ring when the latter is in the high position.
  • the ring 59 comprises a flange 63 or radial arms whose external diameter corresponds to that of the widest necks, which bears on the upper edge of the neck of the container 6 when the spout is lowered inside thereof which has the effect of pushing the ring up and closing a contact of the switch 62.
  • This contact is incorporated in the chain of contacts for detecting the presence of the container 6 which are mounted in series and which prohibit the opening of the solenoid valve 43 as long as one of them is open.
  • the contact of the switch 62 obliges the client to keep the pouring spout 51 engaged in the neck of the container during all the filling and he therefore precisely determines the position of the level sensor 44 relative to the upper edge of the neck of the container.
  • the contact 62 opens and it controls the closing of the solenoid valve 43 and the stopping of the distribution.
  • the switch 62 associated with the sliding ring 59 is a very safe means of detecting the presence of the pouring spout in the neck. As a result, in this embodiment, the contact of the switch 62 can be used to replace the manual button for controlling the start of a cycle.
  • the same sliding ring detection device can be used on the pouring spout 3 articulated around a horizontal axis shown in FIG. 3.
  • the sliding ring may not work reliably. This is why, in the case of an articulated spout 3, provision is made to use, preferably, an optical detector of the presence of the container 6 under the spout.
  • FIG. 3 shows an embodiment of such a detector which comprises a light source 18 situated in the vertical plane perpendicular to the axis 7 which is swept by the spout.
  • the light source 18 is located for example slightly below the front edge of the sink 3 and it emits an oblique ray of light 19 which passes slightly below the free end of the spout in the rest position and which is received by a photoelectric detector 20 located on the vertical wall of the cabinet 1 or behind a hole in this wall.
  • the detector 20 receives the light beam 19 if it is not intercepted by a container 6. It is obviously possible to invert the light source and the photoelectric detector or put them side by side and place a mirror at the other end of the light path.
  • This position in the vertical plane swept by the spout makes it possible to use only a single light beam which is interrupted by a container 6 which necessarily intersects this vertical plane if it is placed under the spout, but which can also even if it is not exactly under the spout.
  • the skeleton plate 11 has a slot or a void located at the intersection of the plate and the vertical plane swept by the spout. This vacuum allows the drops of liquid to fall to the bottom of the sink without leaving a trace on the plate, hence better cleanliness. It also allows the free passage of the light ray and therefore it allows the light source or the photoelectric receiver to be placed under the plane of the stage where they are better protected.
  • the level sensor 44 is constituted by two electrodes placed in a tube 45 which is open at the upper end, it is advantageous to connect the tube 45 to the discharge of a small fan which blows automatically from the air in the tube 45 when the spout is in the rest position in order to dry the electrodes and to avoid risks of parasitic conduction by drops of liquid establishing electrical contact between the two electrodes 44a or between one of them and the mass of the tube 45.
