Warmers for Railway and other Carriages, Applicable also
for the Purpose of Heating Domestic and other Buildings.
We, PAUL BÜSCHE, of 43 Aynhoe Road, Brook Green in the County of Middlesex,
Merchant, and JOHN EBENEZER HOPKINSON, of 15 Walbrook in the City of
London, Engineer do hereby declare the nature of our invention for "IMPROVE-
MENTS IN THE CONSTRUCTION AND METHOD OF HEATING FOOT WARMERS FOR
RAILWAY AND OTHER CARRIAGES APPLICABLE ALSO FOR THE PURPOSE OF HEATING
DOMESTIC AND OTHER BUILDINGS" to be as follows:-
Our Invention relates to improvements in the construction and method of
beating foot warmers whereby we are enabled to retain the necessary heat for a
considerably longer period than by the methods hitherto in use.
We propose in the case of a foot warmer to heat the same by means of a cake
of carbon, or other suitable material, first heated in a furnace and then introduced
into a case or receptacle within the foot warmer; suitable provision being made
for a current of air to circulate freely through the said case, passing around the
heated carbon on its passage. To avoid an excess of direct heat to the fect or floor
we may place over the case or body of our apparatus an outer covering of asbestos
or other non-conducting material.

When our apparatus is to be used not as a foot warmer but for the purpose of
warming an apartment we may dispense with the outer covering of asbestos and
place our apparatus upon any convenient support.
In order that our Invention may be the better understood we have hereunto
annexed a Sheet of Drawings descriptive of our Invention.

Invention.

for the Purpose of Heating Domestic and other Buildings.
We PAUL BÜSCHE of 43 Aynhoe Road, Brook Green in the County of Middlesex
Merchant and JOHN EBENEZER HOPKINSON of 15 Walbrook in the City of
London Engineer, do hereby declare the nature of our invention for IMPROVE-
MENTS IN THE CONSTRUCTION AND METHOD OF HEATING FOOT WARMERS FOR
RAILWAY AND OTHER CARRIAGES APPLICABLE ALSO FOR THE PURPOSE OF HEATING
DOMESTIC AND OTHER BUILDINGS, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :—
Our Invention relates to improvements in the construction and method of
heating foot warmers whereby we are enabled to retain the necessary heat for a
considerably longer period than by the methods hitherto in use.
We propose in the case of a foot warmer to heat the same by means of a cake
of carbon, or other suitable material, first heated in a furnace and then introduced
into a case or receptacle within the foot warmer; suitable provision being made
for a current of air to circulate freely through the said case, passing around the
heated carbon on its passage. To avoid an excess of direct heat to the feet or floor
we may place over the case or outer body of our apparatus a covering of asbestos
or other non-conducting material.
When our apparatus is to be used not as a foot warmer but for the purpose of
warming an apartment we may dispense with the outer covering of asbestos and
place our apparatus upon any convenient support.

page_text: In order that our Invention may be the better understood we have hereunto
annexed a sheet of drawings descriptive thereof.
Fig. 1 being a longitudinal section through foot warmer embodying our invention.
Fig. 2. is an end or front view of the same.
A being the case or shell forming the outer portion of a foot warmer.
B is an inner lining arranged within the same.
C is a sliding tray or drawer.
D cake of carbon.
E chamber within sliding drawer for reception of carbon D.
F chamber to receive spare carbon.
G'G openings for passage of air.
H covering of asbestos or other non-conductor.
It will be seen that our foot warmer consists of an outer shell A, within which
is a lining or inner case B; within this inner lining B is arranged a sliding tray
or drawer C for the reception of the cake of carbon when heated.
Around this drawer and at either end of the outer shell A are a number of
perforations through which the air circulates, as indicated by the arrows.
Although we have described and illustrated our heating apparatus as applied
to the warming of a Railway Carriage in the form of a foot warmer we would
have it understood that we may use such arrangement for heating Conservatories
and other buildings or apartments.
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
we claim is
1. A heating apparatus constructed combined and arranged to operate the
warming by means of a current of air passing over a heated carbon or its
equivalent, placed within it substantially as set forth.
2. A foot warmer or heating apparatus having a case (A) an inner lining (B)
and a drawer or tray (C) to hold a heated cake of carbon (D) or other suitable
material; the outer and inner casings having openings (G) for the introduction of
air for combustion and for the exit of the warm air for heating substantially as
described.
