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.
  • a mason sieve of the type set out in the preamble of claim 1 the cylindrical frame of which consists of two half-shells each having the shape of a semicircle, one of these half-shells, constituting in a way a male element, having at its ends inwardly curved parts intended to engage between the ends of the other half-shell constituting a female element.
  • Such a mode of construction of a frame formed by two different half-shells therefore necessarily involves the provision of different tools or different operations for the shaping of the two half-shells.
  • the cylindrical mason sieve according to patent GB-A-822 309 is shaped so as to allow the stacking of several sieves.
  • each sieve located below the bead forming the internal groove in which the sieve fabric is housed, has an internal diameter smaller than that of the part located above this bead. It is therefore clear that a mason sieve according to GB-A-822 309 requires, when superimposed on other sieves of the same kind, a very large storage volume.
  • 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 sieve comprising a transverse sieving cloth held in a cylindrical peripheral frame having an annular groove in which is housed the edge of the sieving cloth, this frame consisting of two half-shells each having the shape of 'a semicircle, is characterized in that the two half-shells are identical and assembled together by means of closing devices ensuring the connection of the transverse edges opposite the two half-shells.
  • the mason's sieve according to the invention offers the advantage that the two identical half-shells together constituting the frame can be fitted into one another if they are made of a rigid plastic material, or else they can be packaged flat, which reduces the volume required for its storage by around 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 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 Hf is pinched the fabric 1 as shown in Figure 3 or even by a single circle 4 ( Figure 4) in wire metal with a section of 4 mm for example. In the latter case, the screening fabric is blocked on the hoop by a strip crimped onto the wire fabric 1 itself wound on the hoop 4.
  • This metallic screen fabric 1 is. held in a cylindrical peripheral mount 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 semicircle.
  • Preferably each half shell 5, 6 is molded from a rigid plastic material and has a semicircular cross section.
  • 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 half-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, fitting one into the other and remaining fitted 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 rectangular cross section (Figure 3), or 13 to 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 completed by an elastic locking of the closing devices 7.
