sections

32 and 32.

The chamber 33 may, if desired, be packed with any suitable insulating material, or may be filled with poured concrete.

The structure of Fig. 4 is quite similar to that of Fig. 3. Sections 40 and 4U are stacked to dene the main flue 4l', and

sections

42 and 42 are similarly stacked in surrounding relation to the inner column, to define the chamber 43. The sections of the inner column are formed at their lower ends with outwardly oiset terminal anges 44, 'while'the sections of the outer column are formed with inwardly offset terminal anges 45. Any suitable form of separator Vmay be interposed between the ends of adjacent sections.'

For mutually bracing the two columns, the outer walls of the sections 40 may be notched at perimetrally spaced points, as at 46, while the inner walls of the sections 42 may be notched at registering points, as at 41; and tie blocks 48 may be received, and suitably secured, in the registering pairs of notches.

In Fig. 5, lI have shown

sections

50 and 50 corresponding to the sections ID and l' and dening a primary flue i; and sections 52 and 52', corresponding to sections l2 and I2 and defining, with the sections 5I) and 50', a chamber 53. Now the elements, indicated generally by the reference numerals 54 and 56, correspond closely to the elements I1 and 23, except that the element 54 is provided, at spaced points about its perimeter, with outwardly projecting eyelets 55 providing substantially vertical openings, while the element 5B is provided, at registering points, with inwardly projecting eyelets 51 providing vertical openings. Tie bars 58, formed with downt'urned terminal portions adapted to be rel ceived in the eyelets 55 and 51, respectively, provide means for mutually bracing the two columns.

I claim as my invention:

1. A chimney construction comprising a c olumn of superposed tubular sections, a second column of superposed sections surrounding and perimetrally spaced from, but enclosing, said rst column, perimetrally continuous means having a portion gripped between adjacent surfaces of adjacent sections of said rst-named column, said means having portions telescopically engaged with a perimetral surface of each of said sections, perimetrally continuous means having a portion gripped between adjacent surfaces of adjacent sections of said second column and having portions telescopically engaged with a perimetral surface of each of said sections of said second column, and tie means connecting saidrst-named means with said second-named means.

2. A chimney construction comprising a column of superposed tubular sections, a second column of superposed sections surrounding and perimetrally spaced from, but enclosing, said first 4 column, and reinforcing means for said construction, associated with certain of said column sections, each such reinforcing means providing a perimetrally continuous band externally embracing the perimetrally outer surface of a section of said first column, a perimetrally continuous plate flxed relative to said band and gripped between adjacent surfaces of the embraced section and an adjacent section in said column, a perimetrally continuous band internally engaging the perimetrally inner surface of a section .of said second column, a perimetrally continuous plate xed relative to said last-named band and Agripped between adjacent surfaces of the en gaged section and an adjacent section in said second column, and means extended between said bands and providing a bracing connection therebetween.

3. A chimney construction comprising a column of superposed tubular elements, a perimetrally continuous member having a portion resting upon the upper end oi one of said elements, the superjacent element resting upon said member portion and clamping the same in place, and a second column of superposed tubular elements surrounding and perimetrally spaced from, but enclosing, said rst column, said mem-` ber having a portion resting upon the upper end of one of the elements of said second column, and the superjacent element of said second column resting upon said last-named member portion and clamping the same in place, said member further perimetrally engaginga section of each of said columns.

4. A chimney construction comprising a column of superposed tubular sections, perimetrally-continuous means sleeved upon one of said sections and having a portion resting upon the upper end of said section, the superjacent section resting upon said portion of said means to clamp the same in place, a second column of tubular sections surrounding and perimetrally spaced from, but enclosing, said first column. and perimetrally-continuous means telescoped within one of said sections of said second column and having a portion resting upon the' upper end of said last-named section, the superjacent section of said second column resting upon said'portion of said last-named means to clamp the same in place, said perimetrally-continuous means being joined to brace said two columns.

5. A chimney construction comprising a column of superposed tubular sections, a perimetrally-continuous metal tube having a reversely bent intermediate portion projecting substantially perpendicularly out of the general planes of the perimetral walls of said tube and defining an open-mouthed channel, said reversely bent intermediate portion being imprisoned between the adjacent ends of two sections of said column and the perimetral walls of said tube projecting oppositely' from said intermediate portion lying in snug contact with the outer walls of said two sections, respectively, a second column of superposed tubular sections surrounding and perimetrally spaced from, but enclosing, said first column, a second metal perimetrally-continuous tube having a reversely bent intermediate portion projecting substantially perpendicularly out of the general plane of said plate Vand'defining an open-mounted channel, said reversely bent portion of said second tube being imprisoned between the adjacent ends of two sections of said second column and the perimetral walls of said second tube projecting oppositely from said'intermediate portion lying in snug contact with the inner walls of said two sections of said sec.

ond column, respectively and tie means connecting said two metal tubes to provide a bracing connection between said columns.
