Chimney Provided with Air Suction Pipes for Dwelling Rooms.
I, JOSEFII WINGENDER, of 86, Bismarckstrasse, Aix-la-Chapelle, Germany,
Architect, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
My present invention relates to a new chimney provided with air-suction-pipes
for dwelling-rooms. All dwelling-rooms heated by stoves, as school-rooms, sick-
rooms, inn-rooms, parlour, bed-rooms, offices and the like should be provided,
for sanitary purposes, with just as many air-suction-pipes, as there are in such
rooms chimneys for stoves, and that in order to educt by means of such air-pipes.
the impure air from the said rooms.
"
Air-pipes for such rooms answer to the intended purposes, only if they are
manufactured in exceedingly great funnel-shaped dimensions as they are often
found in old farms. But air-pipes commonly used to-day in dwelling-houses and
having, by reason of the sense of beauty, only the same cross-section as the chim-
neys arranged in such houses answer to that purpose but in a small degree,
because the said cross-section is too small; in consequence whereof the activity
of such pipes must be artificially intensified. Such artificial institutions consist
in arranging in the inner air-pipe a gas-heating apparatus or petroleum-heating
one, or, in arranging at the admitting or eduction port an air-sucking apparatus
or an air-pump-ventilator that are propelled by motor power and which enter by
pressing the fresh air and educt by sucking the impure air.;
The most disadvantages found in chimneys are caused by the leakage of the
pipes or. by the different temperatures of the chimney-walls resulting from wind
and weather, whereby exists a bad draught in the chimney.
So it does not seldom arrive, that in a stove, the pipe of which enters a defec-
tive, chimney, even the best coal hardly burn and produce only a small quantity
of heat, while in an other stove similar to the first one, but the pipe of which
enters a correct chimney even worst fuel will burn. ;
Now, my invention relates to a new and useful air-pipe containing the chim-
ney in its middle, and the objects of my improvements are first, to provide means
to avoid leakage in the chimney itself: second to provide artificial stones in
order to build a chimney and an air-pipe simultaneously and by means of the.
same stones; third, to provide means to secure the single stones on to the other
in the bed-joints, as well as in vertical direction; and finally, to afford facilities
for properly maintaining a constant temperature in the chimney.
I attain these objects by means of the chimney with air-pipe represented in
the annexed drawings in which,
Fig. 1 and 2 show the cross-sections of artificial stones, the first one being
provided with an opening to suck. the impure air from the dwelling-room into.
the air-pipe; the other being provided with an opening to have the stove-pipe
entered into the chimney..
Fig. 3 is the plan-view of such artificial stones:

page_text: Fig. 4 is a vertical section of such stones, but there is no side-opening at this
stone,
Fig. 5, represents a vertical section of a wall built by means of such artificial
stones, a stove-pipe being entered into the chimney, and the wall being provided
with an opening to suck the impure air into the air-pipe; and finally.
Fig. 6 is a wall in which several chimney-pipes, made of metal, cement or the
like, are arranged and the air-pipes around the said chimney-pipes are construc-
ted of common bricks.
Similar letters refer to similar parts throughout the several views.
For obtaining the objects of my present invention I. have made three kinds of
artificial stones, and that, firstly, a common stone a (Fig. 3, 4 and 5) containing
the chimney d in its middle, the said chimney being surrounded by the air pipe e,
this stone is not provided with any side-opening; second, and artificial stone C
(Figs. 2 and 5) similar to the first one, but provided with a side-opening f, to enter
the stove-pipe g (Fig. 5) into the chimney; third, an artificial stone c (Fig. 1)
similar to the aforesaid stones but being provided with an opening h to suck the
impure air from the dwelling-room into the air-pipe.
All the three kinds of stones are provided at the four corners with vertical
channels into which, during the wall is constructed, connecting medium is cast
thus producing a fast vertical bond of the stones.
The vertical extremities of the stones are provided each with a continuous
groove or recess k running parallel to the four sides of the stones from one of
the said vertical channels to the other and around the chimney-pipe in the
middle of the air pipe. I prefer to make such groove of a semicircular cross
section, so that, when the stones are put one upon the other, there is in each
bed-joint a circular groove (Fig. 5).
The said grooves are filled up with connecting medium whereafter the chim-
ney as well as the air-pipe are surrounded by a circular rod of connecting medium
which produces the horizontal bond of the stones and prevents leakage of the
chimney as well as of the air-pipe.
The chimney-pipe is connected to the wall of the air pipe by means of two
webs or ribs m and the stones are mounted in such a manner that the ribs of a
stone form a right angle with the ribs of the upper and under stone.
The chimney-pipe in the middle of the artificial stones can be made, separately,
of metal or any other material and can be connected to the wall of the air-pipe.
The wall represented in Fig. 6 is constructed of common bricks that are
mounted in such a way that there are air-pipes, in the middle of which I have
arranged chimney-pipes made of metal or any other material; also there are
side-openings for entering the stove-pipe as well as for sucking the impure air
in the same way as I have above described.
The cross-sections of the chimney-pipes arranged in the said wall are different
from each other and the said openings are directed to both sides of the wall alter-
nately, that is, the wall is a partition for two dwelling rooms.
The side openings h for sucking the impure air is preferably provided with a
venetian blind n in order to regulate the sucking (Fig. 5).
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
In an air-pipe containing the chimney pipe in its middle the combination of
artificial stones a in the middle of which is arranged the chimney-piped the
Jatter being connected to the walls of the air-pipe e by means of webs or ribs m,
the said stones being provided at the four corners with vertical channels and
at each vertical extremity with a groove k running parallel to the sides of the
stones and over the said ribs in and all around the chimney-pipe; with artificial
stones C similar to the aforesaid stones and provided with a side-opening h
extending through the wall of the air-pipe, and with artificial stones 6 similar

page_text: to the first named stones and being provided with a side-opening f extending
through the wall of the air-pipe as well as through the wall of the chimney-pipe,
all essentially as set forth and for the purpose specified.
Dated this 22nd day of February 1899.
