- part 6, by means-of pins 9 passing through the discs 20 of the sions 22. The stem 21, which is substantially of T-shape, is offset laterally in relation to one face of the disc 20 to an extent slightly greater than the thickness of the disc. The disc 20 also comprises, between its center and the part of its periphery from which the stem 21 extends, a-member or stirrup piece 23 fixed, in any suitable removable manner, to the opposite face of the disc. The member 23, which is placed crosswise to the radial axis of the stem 21, forms internally a passage 24 whose height is slightly greater than the thickness of the stem 21 and whose width is less than the dimension between the extreme edges of the extensions 22.

For, making the partition, the stems 21 of a first row of panels 10 are pivotally connected to the iron parts 6 by pins 9 extendingthrough the flanges 6a and 6b and in the holes 25 made in the stems 21 of said panels 10. The distance between the holes provided in the flanges 6a and 6b for inserting the pins 9 is so chosenthat two panels-lfl'tliat are contiguous partially overlap, conflningoverlapping areas 13 and extending at least up to the level of one of the iron flanges 6, for example, flange'6a. Then asecond row of panels 10 is used whose stems 21 may or may not have the hole 25. Eachpanel 10 forming the-secondrow is placed on the corresponding panel 10 of the first row, so that the stems 21 are placed according to the same vertical-axis-while partially overlapping. The holding of the second panel is ensured by member 23 engaging the stem 21 of the second panel, said member 23 being completely fixed on the disc 20 of the first panel. The second panel 10 thusmounted can slidein relation to the first panel to a dimension'corresponding to the radial'extent of the stem 21 between the corresponding peripheral edge of the disc 20 and the lateral 'extensions 2 2.'As can be seen in FIG. 4, the mounting of the second panel l0 is made so that the lateral offsetting of 1 the stem 21 is placed in the same direction as that of the stem 21 of the first panel. 1! follows that between the two assembled panels, there exists'a space 26 corresponding to the thickness of the discs 20. An arrangement of this kind is chosen so that it is possible laterally to overlap the various panels forming each row,-and make overlapping areas 13 between two contiguous panels. V

According to the height of the partition to be made, several rows of panels are assembled and in F 10. 1, the partition comprises five horizontal rows of panels mutually overlapped. In this arrangement, it should be noticed that the lateral offsetting of the stems 21 (-F1G. 4) means that the member 23 of each panel is placed in the exact extension of the disc 20 of the panel immediately below, without then forming an obstacle preventing the free sliding of the stem 21 of a third panel 10.

The finalsetting up .ofthe partition, for instance, after positioning five rows of discs 20-, is done by mounting a lower iron lower panels 10; To this end, the discs 20 of the panels used for making the last row advantageously have a hole 27 in each one of themat a point diametrically opposed to the stem 21.

The partition made as described above is then attached to the roof 3 to extend vertically between the walls 2 which are each providedwith a vertical column 28. Each column has at leastaone hole 29"forr engaging a resilient bolt 30 mounted on.

theendofthe lower iron'part 6 The position of the hole 29 in disc 20;preferably made of thin iron sheetincluding a rigid each column 28 -is choseninrelation to the roof 3 so that the" engaging.ofresilientbolts 30 of the iron part 6 ensures holding of said iron part in a maximum retracted position of the .partitionfor which the panels 1 0'have been subjected to a relative sliding corresponding to the radial dimension of the stem 21 and comprisedzforeach panel: between the extreme edge andthe extensions 22'..Each panel 10'is thus substantially heldabutting'oneither'side of the associated stem 21 against the member 23. of the panel 10 immediately thereabove. So-

thatthepartition-has no empty space, especially level with the edges of the extremevertical rows of panels 10, the iron parts I 6 and6 are connectedby plates31 telescopically inserted on the columns 28 for covering'the'various discs 20 for an extent appreciably equal to half. the overlapping areas 13. in thismanner, the partition has no empty space since the various panels are mutually overlapped by their discs for confining the covering areas 13, and are also partially inserted in the iron parts 6 and 6, and being also covered by the plates 31 with regard tothe discs 20 of the extreme vertical rows of panels 10.

The partition described above is preferably-but not necessarilymounted as a removable partition placed inside a building for dividing up the covered surface with a view to separating different hatches of products or materials. Should fire break out in one of the compartments defined inside the building, the unbolting of the bolts is effected automatically or by hand so as to release the lower iron part 6, which is moved vertically by gravity. During the descending movement of the iron part 6,, the lower panels 10 slide by their stems 21 in the members 23 of the panels immediately above, up to the moment when the lateral extensions 22 bear on said members. It then follows that the row immediately above the discs 20 is also moved in a vertical descending direction for controlling, in a similar manner, the sliding of the panels of the row im mediately above. in this manner, an extension of the partition is made so that the iron part 6, bears on the top edge of the removable partition dividing the covered surface of the building with a view to totally isolating two contiguous compartments so as to limit the risks of causing a fire.

In the extended position shown in FIG. 6, it should be noticed that the discs 20 of the various panels 10 are always mutually overlapped. showing overlapping areas 13. Likewise, the vertical downwards movement of the iron parts 6, entails the telescopic sliding of the various plates 31, so that the partition has no intermediate empty space capable of permitting a draught or hot gas to circulate, which could cause a fire.

The possibility of extending the partition is obviously determined by the radial length of the stem 2] of each panel 10 used and by the number ol'superimposed panels forming vertical rows. Those various data are generally chosen as a function of the space that must be filled in with relation to the fixed or movable partition dividing the covered surface of the build ing, but it is obvious that in certain cases the ability to extend the partition may be greater than the opening to be closed. In such case, the extension of the partition is limited when the iron part 6, abuts against the top edge of the partition or against the ground.

In the example shown in the drawing, the partition comprises vertical rows respectively formed by five superimposed panels 10. FIG. 7 shows the case when the roofing 3' of the building has one or more slopes; the necessary compensation for holding the iron part 6, in a horizontal plane is ensured by interposing, at the corresponding level, vertical rows comprising a greater or smaller number, ofpanels 10.

In FIG. 7, each panel 10 comprises instead of the disc 20, a rectangular plate 20a whose small sides can be rectilinear or curvilinear. The invention is not restricted to the examples shown and described in detail, and various modifications can be made.
