A communication from DEUTSCHE GLÜHSTOFFGESELLSCHAFT MIT BESCHRÄNK-
TER HAFTUNG, of Dresden, in the Empire of Germany.
I, ALFRED JULIUS BOULT, of 323, High Holborn, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a portable footwarmer heated by so-called smokeless
fuel, made of prepared charcoal briquettes or fuel-blocks, and destined for use in
rooms and chambers, carriages, churches and the like..
This new portable foot-warmer is illustrated in the accompanying drawings,
Figure 1 being a perspective view of the complete device and
Figure 2 a longitudinal horizontal section of the heating apparatus enclosed in
the footwarmer.
This footwarmer consists of an oval-formed quadrangular or other shaped hollow
body a of metal or the like, provided with feet b and a handle c on one of the front
sides or ends. On the longitudinal sides this hollow body has round, rectangular
or other shaped openings d. Its upper side is covered with carpet or other suitable
fabric down to the tops of the openings d for the purpose of preventing any
disproportionate radiation of the heat.
At one end, for the insertion of the heating-apparatus, there is an opening
provided with a cover or closure plate e, which is secured to the end of a by a catch
or hook f.
The heating apparatus consists of a box-shaped receptacle g, having its walls
pierced with slots or apertures h. With the aid of woven wire-work, perforated
sheet metal, or other similar material, a compartment gl is formed in the case g of
In this compart-
the foot-warmer, which may be closed by a cover or slide k.
ment the heated and incandescent charcoal-briquettes are introduced, and then the
slide k is closed prior to the insertion of the heating apparatus in the outer case a
of the foot-warmer. As these are played upon from all sides by fresh air, their
incandescence diminishes slowly, and practically endures for a long time.
resulting heat first warms the surface and then radiates through the openings d of
the foot-warmer. The fabric on the top of the foot-warmer a acts as an insulator
or heat-moderator, and prevents contact between the feet and the heated metal, so
that only a tempered heat strikes upon the feet.
The
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondents and in what manner the
same is to be performed I declare that what I claim is :-
1. In a portable foot-warmer the combination with a hollow casing such as a of
an enclosed heating apparatus such as g in the compartment y' of which enclosed
by means of a cover or slide k are inserted incandescent prepared charcoal-blocks
(or smokeless fuel) to which air is admitted by perforations in the walls of the
compartment g¹ substantially as described and illustrated in the accompanying
) drawings.
2. In a portable foot-warmer, the combination with a hollow body or case such
as a provided with perforations such as d of a covering of woven or other fabric

page_text: or material on the upper external surface substantially as described and illustrated
in the accompanying drawings.
3. The combination and arrangement of parts constituting the complete foot-
warmer substantially as described and illustrated in the accompanying drawings.
