спап, I ILEK NA LEMKE, Fitter, Doin or
Magazinstrasse, 12A, III, in the City of Berlin, in the Kingdom of Prussia, and
German Empire, 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:
The subject of the present invention is an improved pipe for setting upon
stoves, closed fireplaces and the like for the purpose of better heating the
room.
On the accompanying drawing
Fig. 1 is a vertical section of the improved pipe and
Fig. 2 is a plan view of the same.
a is the heating pipe which is constructed of corrugated iron and is open at
the bottom and provided at the top with an aperture adapted to receive a hollow
cap b. c is a vertically adjustable partition, the upper part or handle of which
passes through a hole in the cap c.
The invention is adapted for those stoves or other closed fire-places which have
an opening at the top for culinary purposes, or in which a suitable opening can
be provided to receive the bottom of the pipe « so that the apparatus is supported
by the ring d.
The advantages of this improved heating pipe over former constructions are as
follows:
1/. The partition c in the interior of the heating pipe is vertically adjustable and
readily moved by means of the extension e which may conveniently be fixed by
means of a a screw or the like. By this means any required degree of warmth may
be quickly attained by using this apparatus or the generation of warmth may be
altogether prevented. For if the partition is let down to the base of the opening in
the stove or the like the whole of the heating current of heated gases passes
through the apparatus.
The more the partition is raised on the other hand, the more hot gas passes
directly to the chimney without entering the heating pipe.
2./ The cap b is adjustable and the partition being removable cleaning of the
apparatus is greatly facilitated.
3. The heating pipe being corrugated or otherwise figured, the radiating surface
is 2 or 3 times greater than that of a smooth pipe; and this surface is still further
increased by employing a ball or like cap &, the hot gases passing into such cap
or extension of the pipe.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
wo claim is:
1./A heating-pipe for application to stoves, closed fire-places and the like having

page_text: a vertically adjustable partition whereby the quantity of the gases of combustion
passing through can be regulated, substantially as described.
2./ A heating pipe for application to stoves, closed fire-places and the like, as
claimed in Claim 1, wherein the adjustable partition is provided with an extension-
rod for operating it, said rod passing through a cap on the top of the pipe all
substantially as described.
3. A heating pipe for application to stoves, closed fire-places and the like, as
claimed in Claim's 1 and 2, wherein the outer jacket of the apparatus is made of
corrugated iron or similarly figured metal, for the purpose of increasing the
radiating surface, substantially as described.
4./ A heating pipe for application to stoves, closed fire-places and the like, as
claimed in Claims 1, 2 and 3, wherein the heating-pipe proper is provided with an
enlargement or extension-cap, the top of which may conveniently be formed as a
funnel, substantially as described...
