My invention relates to the ‘construction-[of
chimney attachments for the'outside‘ of buildings,
and, in particular, to inexpensive chimney con
structions suitable for cabins, cottages and'the
like.

Due to the ‘work and expense involved ‘in the
construction of brick chimneys, and to the neces
‘where ‘the pipe‘ 0 ‘extends‘thru‘ thefbu'il'ding wall
10! is protected byv an insulated‘thimble‘ id‘ of usual =5
1‘construction thru the ‘center of which the pipe 0
passes; Securedlto the outside" surface [of’fthe
the inexpensive or temporary types, to provide, on
building wall mgr-‘parallel with the outside vertical
‘extension of the pipe‘ 0,‘ are fastened'me‘tal strips
a. formed‘ into'a'channel shapepas shown in Figs. 10
the outside of such buildings, in place of brick
chimneys, merely stovepipes made of sheet iron, or
"?angesb which are secured‘to the outside‘ surface
sity of providing adequate support ~ for vtheir
weight, it is customary‘in cabins and cottages of
1O
usual sheet iron stovepipe ‘leading from the stove I‘
s to the outside oi‘the buildingandthence upward
to extend above the edge ‘of the roof. The place
‘ in some instances of terra cotta.‘ Such construc
tions are ugly in appearance, more or less tem
porary, and also often constitute a ?re hazard.
One object of my invention is to provide an
inexpensive outside chimney attachment which
is easily constructed and easily set up into place.
Another object of my invention is to provide a
chimney construction which will offer greaterpro
2 O tection against ?re than the common types of
chimneys above referred to.
Another object of my invention is to provide
a chimney construction of permanent character,
and of comparatively light weight so that, when
25 the chimney is attached to the building, it will
not cause any strain on the building tending to
result in any uneven. settling of the building.
A further object of my invention is to provide
a chimney suitable for meeting the above men
30 tioned requirements, which, due to its construc
tion, will incidentally present a pleasing external
appearance and, consequently, be more attrac
tive than the conventional stovepipes protruding
' from the outside walls.
These and incidental objects and advantages I
attain by making my chimney of prefabricated
metal members, so that the chimney can be easily
set up into place or taken down and moved. The
details of construction of my invention are here
inafter described with reference to the accom
panying drawing, in which:
Fig. 1 is an elevational view showing my chim
ney attached to the outside of the wall of a
building;
Fig. 2 is a vertical section of the building wall
in which my chimney is installed, the section cor
responding to line 2——2 of Fig. 3;
Fig. 3 is a horizontal section on the line 3-3 of
Fig. 2 looking in the direction indicated by the
arrows; and
'
Fig. 4 is a fragmentary perspective view of the
metal strip a which constitutes one of the ele
ments of my construction.
Referring ?rst to Figs. 2 and 3, 0 denotes the
3‘1 and‘lll ? ‘These metal strips-d are provid‘edr'with
of the wall=by's'crews. “The outside vertical ex
tension ofithe'pipe c is supported by metal straps
or brackets e', the ends ofwhich are attached by ‘15
bolts 0, to» the upper metal strip a as shown in Fig.
2. These brackets hold the outside section of
pipe 0 in‘ position and rigidly spaced from the strip
a, and thus from the outside surface of the build
ing wall. On the upper end of pipe 0 is prefer
ably mounted a metal conical hood 1‘ of the usual
type.
When the strip a, the outer extension of the‘
chimney pipe 0 and the brackets e have been
secured in place, a three-sided outer metal hous- 25
ing 9 is then set up and attached to the strips a
by suitable bolts extending thru the sides of the
strips a and the edges h and a‘ of the metal hous
ing 9, as shown in Fig. 3. The metal housing g
is made of a single metal sheet which is pressed 30
into shape as shown, and is preferably painted on
the outside to resemble brick or stone, as illus
trated in Fig. 1. The lower ends 19 of the two sides
of the housing 9 are preferably out off at an angle
(see Fig. 2) , and the bottom end k of the middle 35
portion of the housing g is bent inward, and is
cut so as to extend about half way down the
sloping edges of the ends 11; thus leaving a
space at the bottom of the housing 9 for air to
enter freely into the inclosure and circulate 40
around the outer extension of the pipe 0. This
inclosure thus formed by the housing g is sur
mounted at the top by a tapering transitional
metal ?tting or hood m, cut to ?t tightly around
the pipe 0. The lower edge of this ?tting over- 45
hangs the walls of the housing g, and this ?tting
is supported by brackets q, attached to the upper
end of the housing g, which hold the ?tting m
spaced from the upper edges of the walls of the
housing g, thus providing an opening m’ for the 50
escape of the heated air under the edge of the
?tting m, at the same time keeping out the
weather from the space inclosed by housing g as
mentioned. The chimney is completed by the
insertion of a metal strip n between the ?tting m 55

and the roof of the building for the purpose of
diverting the water from that portion of the roof.
It will be apparent from Figs. 1 and 2 that the
housing 9, made and set up in the form de
scribed, not only furnishes a protective covering
for most of the outside chimney pipe 0, and pro
tects the pipe from rusting, but incidentally is
an improvement in appearance over other cheap
outside chimney constructions.
10'
Furthermore, the circulation of air about the
said housing terminating below the top of said
pipe, a hood covering the upper end of said
housing, the upper end of said pipe extending
thru said hood in close ?tting relation, the rim
of said hood overlying the upper end of said
housing, said hood spaced from the upper end of
said housing to permit the passage of air between
said hood and said housing, the bottom end of
said housing extending below said pipe and the
bottom of said inclosure being open to permit 10
air to enter said inclosure.
2. In combination with a stovepipe extending
out of the top of the space inclosed by the hous
thru a building wall and thence vertically up
ing 9', and the protection afforded to the outside ' ward on the outside of and spaced from said
15 wall of the building by the upper metal strip a
wall, an inclosure for said pipe, said inclosure
and inclosed air space a’, act as a safeguard in comprising a plate attached to said wall between 15
the event that the pipe 0 becomes overheated.
said wall and said pipe, the width of said plate
Some modi?cations of course may be made in being greater than the diameter of said pipe, a
pipe 0, with the provision made for allowing cool
air to enter the bottom p’ and the hot air to pass
the constructional details above described, and,
20 therefore, I do not limit myself to such details
except as necessary to carry into practice the
principle of my, invention.
