An improved Construction of F 437
Box-iron.
I DAVID WILSON of The Wilson Engineering Company, Limited, 227 High
Holborn, Middlesex, Stove and Range Manufacturers, do hereby declare the nature of
this invention to be as follows:-
This invention relates to an improved construction or arrangement of Gas heating
Box-iron, notably in lining a metal box made to the ordinary shape of an iron with fire
clay or equivalent material sectioned by a screen or partition provided with apertures
through which gas from an upper to a lower chamber can issue and act upon the
bottom layer for communicating heat to the bottom proper of the iron through the
intermediation of the fire clay.
The fire clay or equivalent material is moulded to shape and dropped into position
and cemented in, or otherwise, to hold it firmly. This fire clay lining may be in more
than one piece and one portion may be of greater thickness than another to retain the
heat where most required.
The casing or upper part of the box-iron may be lined with a non-conductor of heat
to prevent radiation and gas from an atmospheric burner can be led into the first
chamber for distribution in the second or lower and a portion of the casing may
be perforated for the admission of air to be consumed with the air and gas, or by the
gas alone.
non-
The fire clay may be coated or surrounded except at the bottom with a
conductor of heat so that the full value of the flaines can be utilized with great
economy.

I, DAVID WILSON of The Wilson Engineering Company Limited 227 High Holborn,

invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-

The manner of carrying this invention into effect will be understood by reference to
the annexed drawings. Figure 1 is a plan (with lid removed) and Figures 2 and 3
section and clevation respectively of a box-iron a. 6 is the fire clay lining. c the
screen or partition forming an upper chamber provided with apertures 'd, d, for the gas
to issue into the lower chamber e. ff, are the holes at the side of the metal box a by
which the air may enter, and g, g, are similar holes at the back of the box. / is the
aperture or slot for the escape of vapour &c.
Figure 4 is a longitudinal section showing the fire clay lining for use alone or in
combination with any suitable non-conductor of heat i. j is a perforated metal plate
to break up the currents of air entering by the holes f, f.
One of the advantages derived from partitioning the internal lining into two
chambers is that a charge of gas is held in reserve in the upper chamber for
consumption in the lower chamber at all times while the gas is on, there being no

page_text: possibility of the flame being extinguished by any rapid back movement of the iron
such as occurs in all other constructions of gas heating box-irons.
Another advantage is by arranging the holes at the bottom of one side only or at
said side and back for a supply of air to support combustion in conjunction with
the top aperture of the other sido permits a free flow of air into and vapours from
the iron.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is
The internal construction or arrangement of gas heating box-iron as herein before
described and substantially as shown in the annexed drawings.
