Abstract

Two flue blocks 1 and 2 have their adjacent axial ends 4 and 5 of circular cross-section and their opposite ends 3 and 6 of square cross-section. Intermediate lateral surfaces 8 and 9 of the ends 4 and 5 are of circular cross-section and come face-to-face such that the block 1 can turn on the block 2. This enables a section of a flue, consisting of a column of rectangular blocks, to be orientated at any desired angle relative to a second similar section. <IMAGE>

Description

SPECIFICATION A flue block According to the present invention, there is provided a flue block having one axial end of substantially circular cross-section and its opposite axial end of substantially rectangular cross-section.
The block is for co-operation with another flue block having one axial end of substantially circular cross-section and its opposite axial end of substantially rectangular cross-section, such that the other flue block can turn, with its one axial end, on the one axial end of the first block. For this reason, the one axial end of the first block has at least one lateral surface thereof of substantially circular cross-section whilst the one axial end of the other block has at least one lateral surface thereof of substantially circular cross-section and arranged to come face-to-face with the firstmentioned lateral surface in the co-operating condition of the blocks.
Such lateral surface is preferably an intermediate lateral surface between the outer peripheral surface and the inner peripheral surface of the one axial end and obtained by the one axial end being stepped radially.
A device consisting of the first and other blocks is particularly applicable to enabling one part of a flue consisting of a column of blocks of substantially rectangular cross-section to have another part thereof constructed with its substantially rectangular cross-section displaced at any desired angle about the axis of the first part.
Where, for example, the other part of the flue comprises a bend having its axis in the plane of the axis of the first part of the flue, the bend can be orientated at any desired an gular position around the axis of the first part of the flue. If the other part of the flue is straight and co-axial with the first part of the flue, then the other part can have its substantially rectangular cross-section orientated at any desired angular position about the common axis relative to the substantially rectangular cross-section of the first part.
In order that the invention may be clearly understood and readily carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which: Figure 1 shows a vertical section through a device consisting of a pair of flue blocks of a flue, and Figure 2 shows an exploded perspective view of the two blocks.
Referring to the drawings, the flue blocks 1 and 2 are included in a column of flue blocks or a flue. The block 1 has an upper axial end 3 of square cross-section and a lower axial end 4 of circular cross-section, whilst the block 2 has an upper axial end 5 of circular cross-section and a lower axial end 6 of square cross-section. Each end 3 to 6 is stepped so as to have a lateral surface 7 to 10, respectively, intermediate its outer peripheral surface and its inner peripheral surface.
The end 3 has its inner and outer peripheral surfaces and its surface 7 all of square crosssection, as does the end 6, although the surface 7 faces inwardly, whilst the surface 10 faces outwardly. The end 4 has its inner and outer peripheral surfaces and its lateral surface 8 of circular cross-section, as does the end 5, although the lateral surface 8 faces outwardly and the lateral surface 9 faces inwardly. A suitable fixing and sealing mortar 11 is provided between the blocks 1 and 2.
In constructing a flue of generally square cross-section, a number of flue blocks of solely square cross-section and with stepped ends are fitted one upon another with the interposition of suitable mortar. At a level at about which it is desired that the next flue block of solely square cross-section should be orientated at such an angle that it cannot fit into the top of the flue block last laid, the block 2 is fitted into the top of the block last laid, with the interposition of suitable mortar, and then (as seen in Fig. 1) the block 1 is fitted upon the block 2, with the interposition of the ring of mortar 11, in such a manner that the square cross-section of the axial end 3 is orientated at the desired angle of displacement about the common axis relative to the square cross-section of the lower part of the flue.Then the flue is continued upwards by fitting straight and/or bent blocks of square cross-section in a column on the block 1.
1. A flue block having one axial end of substantially circular cross-section and its opposite axial end of substantially rectangular cross-section.
2. A block according to Claim 1, wherein said one axial end has an intermediate lateral surface thereof of substantially circular crosssection.
3. In combination, first and second flue blocks each having one axial end of substantially circular cross-section and its opposite axial end of substantially rectangular crosssection, such that the second flue block can turn, with its one axial end, on the one axial end of the first block.
4. A combination according to Claim 3, wherein the one axial end of the first block has a lateral surface thereof of substantially circular cross-section, whilst the one axial end of the second block has a lateral surface thereof of substantially circular cross-section and arranged to come face-to-face with the first mentioned lateral surface in a co-operating condition of the blocks.
