PROVISIONAL SPECIFICATION.
Improved Heater for Hot Air Engines, Bath-heaters, and such like
Apparatus.
I, PAUL KIRSTEN, of 48, Schillerstrasse, Chemnitz, Saxony, German Empire,
Technician, do hereby declare the nature of my said invention to be as follows:-
This invention relates to an improved heater for hot air engines bath-heaters,
and such like apparatus, and according to my invention the lower end is surrounded
by a bell-shaped extension for the purpose of rendering as complete as possible the
radiation of the heat of the flame produced, for instance, by a gasified combustible,
contained in a receptacle and applied to heaters such as are employed, for instance,
in connection with hot air engines, and for bath-heaters and for similar purposes.
Between the said bell-shaped piece or extension and the lower part of the heater,
a flat ring enters from below, which serves for the better guiding of the flame
under the lower end of the heater and the bell-shaped extension.
The object attained by the bell or hood like projection which extends beyond the
lower end of the heater is that the entire heat generated is kept together under the
bottom of the heater and the intermediate ring acts to a certain extent as a fire
bridge, whereby a complete combustion and the development of a high temperature
directly under the bottom of the heater is attained.
Dated this 24th day of February 1897.

COMPLETE SPECIFICATION.
Improved Heater for Hot Air Engines, Bath-heaters, and such like
Apparatus.
I, PAUL KIRSTEN, of 48, Schillerstrasse, Chemnitz, Saxony, in the Empire of
Germany, Technician, do hereby declare the nature of my said invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to an improved heater for hot air engines, bath-heaters
and such like apparatus, and I will fully describe same, as adapted for the former
purpose, in reference to the accompanying drawings, in which Fig. 1 is a view
partly in front elevation and partly in longitudinal section of a duplex heater,
and Fig. 2 is a horizontal section on line A B of Fig. 1.
TT are the heaters, the lower end e of each of which is surrounded by a bell-
shaped extension a for the purpose of rendering as complete as possible and utilising

page_text: the radiation of the heat of the flame produced, for instance, at burners such as g g¹
by a gasified combustible contained in a receptacle such as f and applied to the
heaters, such as are ordinarily employed, for instance, in connection with hot air
engines, and for bath-heaters and for similar purposes..
Between the said bell-shaped piece or extension a and the lower part of the
heaters TT, a flat ring benters from below which serves for the better guiding
of the flame under and about the lower end of the heater and through the
passages c and d formed by the said flat ring 6 within the bell-shaped extension.
The object attained by the bell or hood-like projection which extends beyond
the lower end of the heater is to ensure that the entire heat generated is kept
together under the bottom of the heater, and the intermediate flat ring b acts to a
certain extent as a fire bridge, whereby a complete combustion and the development
of a high temperature directly under the bottom of the heater is assured.
It is obvious that the invention may also be used for bath heating and like
apparatus and in adapting it thereto the heater may for example be placed at or
form the bottom of the bath or be arranged in any convenient place and in such
manner as to allow circulation through the heater of the liquid to be heated.
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:
An improved heater used in connection with hot air engines, bath-heaters and
such like apparatus, fired from below by a gasified combustible, and characterized
by a bell-shaped or hood-like extension a at the lower end e of the heater and a flat
ring b situated between the latter and the said extension substantially as described
and shown in the drawings.
