Improvements in or relating to Heating Apparatus for use in
Shop Windows or the like.
I, EMIL BUSCH, Florist of 84 Friedrichstrasse Friedrichshagen, near Berlin,,
Germany, do hereby declare the nature of my invention and in what manner
the same is performed to be particularly described and ascertained in and by the
following statement :-
The object of the present invention is to provide an easily transportable stove,.
by means of which the ice frozen on shop windows may be quickly thawed or the
small spaces behind such windows quickly heated in order to prevent the moisture
on the glass from freezing and thus obscuring from the public view objects laid out
for show.
The apparatus consists mainly in a small receptacle or reservoir having a fire
suitably arranged underneath the same and connected to a pipe system as herein
after more particularly described.
In order to make my invention more easily intelligible reference is had to the
accompanying drawings, in which similar letters denote similar parts throughout
the several views :-
Fig. 1 is a vertical section through one form of stove.
Fig. 2 is a similar section through a modified form of stove and the pipe system
in connection therewith.
Fig. 3 shows a modified form of pipe for the pipe system.
The apparatus as shown in Fig. I may consist of a small receptacle or reservoir A
having vertical tubes B running through it, round which water may circulate, such
receptacle being advantageously heated by means of an oil lamp e arranged
underneath it, and being connected to the pipe system as herein after described.
Another form of stove however, is that shown in Fig. 2, which consists of a
cylindrical vertical receptacle a having central flue a¹ running right through it
and having inside it surrounding the central flue, a tubular coil 6 passing out of the
said receptacle or boiler at its upper and lower ends c d said receptacle or boiler
being heated advantageously by means of a small oil lamp e.
C
The coil 6 is connected by means of bent pipes gh to a hot water pipe system
consisting of telescopically arranged horizontal pipes k k having glands and
communicating with each other at both ends. In order however to ensure the
circulation of the hot water in the said pipe system the end chambers or pipes are
provided with partition walls m m. The pipes 9h are connected to the coil and the
pipe system by means of unions ff and ii and the whole system is filled with water
through the funnel having a vertical pipe communicating with h, said funnel
being situated above the uppermost pipe k k', or the said pipe system may be filled
by means of a funnel p communicating with the uppermost end of the coil 6 and
shown in dotted lines in Fig. 2. The reservoir or receptacle a or A. may be filled
by means of a funnel n. All funnels should be provided with cocks as shown.
A cock y is provided at the further end of the pipe system to permit of the escape
of the air when filling the apparatus with water.
In case the apparatus is to be a fixture the telescopic arrangement of the
tubes k k¹ may be omitted and one pipe k employed as shown at Fig. 3.
The apparatus works in the following manner:-After the pipe system and the
receptacle or boiler have been filled with water, the lamp e is lighted, and the water
in the boiler or recipient heated. By this means the water in the coil will be
heated too and the circulation throughout the whole system will commence, the
hot water rising through pipe g and the colder water descending through pipe h.
If it is required to thaw the ice frozen on a shop or other window, the apparatus

page_text: is placed in the said window with the pipe system against the glass in the manner
shown in Fig. 2; after the window has been thawed, the pipe system may be
removed from the same by loosening the unions ff and ii and turning the pipes g
and back about a quarter of a turn, so that simultaneously the whole system may
be thrown back from the glass, when the unions should be tightened up and the
pipes will stand at about the same level as the stove, at the back of the space
behind the window.
The diameter of the pipes and the distance of the same from each other depend
entirely on the size of the window for which they are required.
Instead of hot water steam or hot air may be employed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1-A transportable apparatus for thawing shop and other windows as also for
heating the space behind such windows consisting of a hot water, steam, or hot air
generator, in combination with a pipe system of a fixed or adjustable length
substantially as described.
2: The combination of a receptacle or boiler, an adjustable pipe system
consisting of horizontally telescopically arranged pipes k k¹, vertical end connecting
pipes having partitions m, pipe connections g h between the pipe system k k¹ and
the said boiler and means for filling said boiler and pipe systems with water
substantially as described.
3: The combination of a receptacle or boiler having a heating arrangement e,
the pipe system consisting of nonadjustable pipes k, and end connecting chambers
having partitions m, connecting pipes 9 and h, unions and i and means for filling
said receptacle and pipe system substantially as described.
