PROVISIONAL SPECIFICATION.
Improved Apparatus for the Heating of Apartments by Mineral
Oil Lamps.
I LOUIS SEPULCHRE, of Herstal near Liège, in the Kingdom of Belgium,
Manufacturer, do hereby declare the nature of this invention to be as follows:
This invention relates to apparatus for the heating of apartments which I
will proceed to describe with reference to the accompanying drawing, upon
which :-
Figure is an elevation of an apparatus of my invention,
Figure 2 an elevation, partly in section, showing a modification of same, and
Figure 3 an elevation, also partly in section, of another modification thereof.
My apparatus consists of a plate P, plane, convex or concave, fitted upon
supports s which keep it horizontally above the ground and at a suitable distance
above a lamp L placed on the ground or in proximity thereto (see Fig. 1).
This plate P may be surrounded with a rim turned downward or gallery G (see
Fig. 2) forming a bell for holding the products of combustion.
I preferably make use of a plate convex downward, as in Figs. 1 and 2, in
order to preserve the burner and the oil reservoir from the direct radiation of
the plate P.
With the object of increasing the heating surface and forming a chamber for
accumulation of heat and less exposed to the entrance of cold air, I have recourse
to a reflector R, plane, convex or concave, but preferably convex as at Fig. 3, fitted
to the plate P or to the gallery G. This reflector is pierced in the centre with an
opening O giving access into the chamber C, to the products of combustion which
also issue from this chamber by the same opening O.
The reflector R, as well as the gallery G, may also be provided with special
openings for disengagement of the products of combustion.
The plate P, which receives the stroke of the flame, heats by radiation upward.
The effect of the reflector R, divergent, is to send the heat towards the ground
and to unite with the heat radiating directly from the lamp L in heating the lower
part of the apartment, so that a person seated near the apparatus warms equally
his knees and his fect.

COMPLETE SPECIFICATION.
Improved Apparatus for the Heating of Apartments by Mineral
Oil Lamps.
I LOUIS SEPULCHRE, of Herstal near Liège, in the Kingdom of Belgium,
Manufacturer, 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 invention relates to an improved apparatus for the heating of apartments
by mineral oil lamps, and has for object the reflection and radiation of the heat
produced by the combustion of the lamp in such a manner as to distribute the
heat equally throughout the upper and lower part of the apartment.

page_text: In order that my invention may be the more readily understood I will now proceed
to describe the arrangement with reference to the sheet of drawings filed with the
Provisional Specification, on which :-
Figure 1 is an elevation of an apparatus of my invention.
Figure 2 an elevation partly in section showing a modification of same, and
Figure 3 an elevation also partly in section of another modification thereof.
My improved apparatus consists of a plate P, which may be either plane, convex,
or concave in form, fitted upon supports s which keep it horizontally above the
ground and at a suitable distance above a lamp L, placed on the ground or in
proximity thereto, as shewn on Figure 1.
This plate may be surrounded with a rim turned downwards, or gallery G,
shewn in Figure 2, forming a bell for holding the products of combustion.
Preferably I make use of a plate convex downward, as shewn in Figures 1 and 2
in order to protect the burner and the oil reservoir from the direct radiation of the
plate P.
With the object of increasing the heating surface and forming a chamber for
accumulation of heat less exposed to the entrance of cold air, I employ a
reflector R, plane, convex, or concave, but preferably convex as in Figure 3,
fitted to the plate P or to the gallery G. This reflector is pierced in the centre
with an opening O giving access into the chamber C to the products of combustion
which also pass out from the said chamber by the same opening. The reflector R,
as well as the gallery G, may also be provided with special openings for the escape
of the products of combustion.
The plate P upon which the flame impinges, imparts heat by radiation upward.
The effect of the reflector R, divergent, is to send the heat towards the ground aud
cause it to unite with the heat radiating directly from the lamp L in heating the
lower part of the apartment, so that a person seated near the apparatus warms
simultaneously his knees and his feet.
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. In apparatus for warming rooms by means of mineral oil lamps the use of the
flat or convex plate P in combination with or without the gallery G and reflector R,
substantially as and for the purposes described.
