Definitions

  • the present invention relates to a mason's screen comprising a transverse screen fabric held in a cylindrical peripheral mount having an annular groove in which is housed the edge of the screen fabric.
  • a mason sieve comprising a cylindrical peripheral frame in one piece, in rigid material such as wood, metal, or plastic, which is split and provided with a closing device making it possible to tighten the cylindrical frame in one piece around the edge of the transverse screen fabric.
  • a screen if it makes it possible to change the screen fabric relatively easily, nevertheless has the disadvantage of having a very large bulk which results, on the one hand, in a very high transport cost and , on the other hand by a very large volume which must be provided for its storage.
  • these sieves are transported without being packaged, they very often suffer damage during transport.
  • the present invention aims essentially to remedy these drawbacks by providing a mason sieve of particularly simple design and which can be stored in a small volume.
  • this mason's sieve comprising a transverse sieving cloth held in a cylindrical peripheral frame having an annular groove in which the edge of the sieving cloth is housed, is characterized in that its frame consists of two half-shells identical, each wound in a semicircle and assembled together by means of closing devices ensuring the connection of the transverse edges opposite the two half-shells and cooperating with each other to assemble the cylindrical frame.
  • the mason's sieve according to the invention offers the advantage that the two half-shells together constituting the frame can be fitted into one another if they are made of a rigid plastic material, or still they can be packaged flat, which reduces the volume required for its storage by about 83%.
  • This reduced packaging, as well as the small footprint, make it possible to carry out long and even very long distance shipments, in good conditions of cost and safety.
  • the various constituent elements of the sieve (frame and wire mesh) can be packaged in cardboard packaging protecting them from any damage.
  • the mason's sieve according to the invention which is shown in the drawing, comprises a circular metallic sieving fabric 1 whose edge is stretched over a peripheral circle.
  • the peripheral circle can in fact consist of two concentric circles of flat iron 2 and 3 between which the edge of the fabric 1 is pinched, as shown in FIG. 3 or even by a single circle 4 (FIG. 4) in wire of a section of 4mm for example.
  • FIG. 4 a single circle 4 in wire of a section of 4mm for example.
  • the blocking of the screen fabric on the circle is ensured by a strip crimped on the metal fabric 1 itself wound on the circle 4.
  • This metallic screen cloth 1 is held in a cylindrical peripheral frame which, according to the invention, consists of two identical half-shells 5,6 each wound in a semicircle.
  • Each of the half-shells 5, 6 may consist of a piece of strip of flexible plastic material injected flat and which is then curved in a semi-circle.
  • Preferably each half-shell 5,6 is molded in a rigid plastic material and has a cross section in a semicircle.
  • Each piece of tape has a rectangular shape and has, for example, a length of 628 mm and a width of 120 mm.
  • the two dei-shells 5, 6 are assembled together, to form the cylindrical frame, by means of closing devices 7 ensuring the connection of the transverse edges opposite the two half-shells 5, 6.
  • Each closing device is advantageously made up by two male and female elements, provided respectively at the two opposite ends of each half-shell 5, 6, which fit one inside the other and remain nested by elastic locking.
  • the half-shell 5 has, along its transverse edge, a tongue 8 projecting outwards and that the other half-shell 6 has, along its transverse edge in manhole 9, a groove 9 made in an extra thickness 10.
  • the tongue 8 is engaged in the groove 9 and retained therein by a part of the extra thickness 10 forming an elastic hook 11.
  • All the constituent elements of the locking device advantageously come from molding with the remainder of the two half-shells 5 and 6.
  • each half-shell 5, 6 has, at an appropriate distance from one of its longitudinal edges, a longitudinal groove 12 with a rectangular cross section (FIG. 3), or 13 with a semicircular cross section (figure 4).
  • the shape of this groove is obviously adapted to that of the circle bordering the screening fabric 1.
  • the two half-shells 5 and 6 are applied around the screen fabric 1 so that the circular edge of the latter comes to lodge in the groove 12 or 13 of the two half shells 5 and 6. the assembly is terminated by an elastic locking of the closing devices 7.
