HENRY BOXALL, of the City and County of Bristol. "IMPROVEMENTS IN THE
METHOD OF AND APPARATUS FOR WARMING AND HEATING."
The heater constructed according to this Invention consists of a portable metallic
case, by preference of a flat shape and about square, say, for some purposes, 12 to
14 inches each side, and about 4 inches deep, or so as to be conveniently placed in
an ordinary kitchen oven.
This case is provided with a stoppered aperture for filling it with an earth or
other dry substance suitable for retaining its heat for several hours; it is also
fitted with a hinged handle or handles for carrying it by.
The mode of heating it is as follows:-The heater is placed in the kitchen oven
for about one hour; it thus becomes sufficiently heated for use, and will then
retain its heat for some hours, and when cooled down may again be heated without
cost and with very little labour. No extra fire is wanted to produce the heat.
I will now enumerate some of its uses:-For warming the feet as a foot stool in
cold weather it is invaluable to invalids, as it may be thus used either in the house
or for travelling by a carriage or railway; to take the place of hot water bottles
for beds, it may be placed in any position required; it is specially useful for
invalids affected with rheumatism or other complaints arising from cold; the heater
can also be used for airing clothes, beds, and bedding; where a small warmth is
required in a sitting or bed room the heater will save the labour of lighting a fire;
it can be used to form a Turkish bath either in a chair or in the bed. Advantages:—
No extra fire is required; no cost for materials; very little labour in using ;
effectual for the purposes above named; the construction is also simple and
inexpensive, and the apparatus is free from smoke or smell.
