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 hollow box-iron, which is adapted for heating by
means of solid glowing fuel, such as charcoal or other similar combustible, more
especially in the form of briquets or blocks of compressed fuel. This improved
iron differs from the well-known box-iron in general use by reason of the following.
characteristics ;-
-
The construction of the upper part as a hollow shell, rounded in form which is
fitted to a flat lower part by a hinge; the bell-shape of the said upper part, which
enables flounces, frills, ribbons and the like to be fluted, and goffered, which is
impracticable with the ordinary box-shaped iron; a special arrangement of ash-
tray, circumscribed by a number of prismoidal studs, surrounding the central
portion of the heating area; its peculiar air-feed arrangement in the form of a
tubular or canal-shaped gallery, on the bottom plate or sole of the iron; and
further also the special mode of heating, and the double-action wedge device for
closing the box-iron.
i
On a hollow base which may be of any desired form in plan, is seated an upper
part or shell hinged to the first whereby it is capable of being turned or pivotted
on a bolt passing through eyes in two lugs cast on the base. The said upper part
is formed of a bell-shaped shell, and provided with a suitable handle; and the
opening in the shell through which the bolt or pivot passes is flattened or made
oval so as to give a certain amount of play to the said upper part and allow it to
slide to and fro on the base, and as the base is slightly larger the top in the closed
state will not rest upon the outer margin of the base, but upon the studs which are
trapezoidal in shape and taper upwards, and are arranged at regular intervals apart
and at a regular distance away from the outside rim of this part, and surround the
interior heating space, so as to prevent the fuel from falling out without hindering
the free access of air. Thus the glowing block of fuel lies, open on all sides, in
the body of the iron, so that the air can reach it freely, being heated by contact
with the hot studs and walls of the iron. This arrangement is of great practical
value for the enhancement of the heating power; and the more so because the fuel
placed in the point of the iron is freely played upon by the air and is brought to a
glowing heat, at the point where heat is most wanted; whereas in the ordinary
box-irons, this is the part where the least heat is developed, owing to the lack of an
efficient air supply; wherefore such irons are comparatively cold at the point.
Openings in the upper shell give vent to the hot air.
The canal-shaped space between the wall of the base and the prismoidal studs
serves as an ash-pan, and provides so large an area for that purpose, that the
improved box-iron may be in use for several hours, without the ash-pan becoming
so choked with ashes as to interfere with the air-supply and necessitate emptying.
The floor of the same is formed to slope inwards all round to facilitate the removal
of the ashes, which when the iron is closed can readily be effected by laying the
iron down on its side. Further also this arrangement has the advantage of
preventing even with the most unskilful handling, all risk of the linen etc., being
гр.

page_text: smudged in the laundry by the falling out of small cinders, ashes and dust; a defect
which can never be entirely got rid of under the old arrangement of air-holes above
the sole of the iron. Moreover the bosses on the floor of the box-iron are so
arranged that those ranged towards the outside of the central heating space are
higher than those ranged nearer the centre; by reason of which the heated fuel
stands askew with an inward inclination, which obviates all difficulty in closing the
iron. At the same time the bell-shaped shell of the upper part when closed down
on the outer edge of the studs tends to press any loose particles of glowing fuel
inwards.
On the bottom surface of the central heating space, also a curvilinear rib encloses
a hollow or basin which for heating purposes serves to hold spirit while the
perforated bed-plate may be utilized to receive the fuel, its front edge being slipped
under the pivot of the bell-shape top and the handle being laid on the point of the
base. In this way the heating of the iron can be attended to with certainty and
celerity without further trouble.
The base or body of the box-iron is provided with a sharp cone-shaped point and
is rounded off at the edge behind for use as a glazing-iron.
As a closing device to secure the connection of the bell shaped top with the base
or body a catch is arranged to turn on a pivot fixed to the back of the base; this
catch slides on a wedge-shaped block fixed to the back plate of the top causing a
forward displacement whereby the nose is made to engage in a notch on the base
establishing the firm connection of the parts, so as to prevent the lifting or turning
back of the bell-shaped' top.

I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, 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:-
This invention relates to a hollow box-iron which is adapted for heating by
means of solid glowing fuel such as charcoal or other similar combustible more
especially in the form of briquettes or blocks of compressed fuel. This improved
iron differs from the well-known box-iron in general use by reason of the following
characteristics ;-
The construction of the upper part as a hollow shell, rounded in form which is
fitted to a flat lower part by a hinge; the bell-shape of the said upper part, which
enables flounces, frills, ribbons and the like to be fluted and goffered, which is
impracticable with the ordinary box-shaped iron; a special arrangement of ash-
tray, circumscribed by a number of prismoidal studs, surrounding the central
portion of the heating area; its air-feed arrangement in the form of an open
channel or space on the bottom plate or sole of the iron; and further also the
special mode of heating, and the double-action wedge device for closing the
box-iron.
The accompanying drawing shows the improved box-iron.
Figure 1 is a side view with the front portion of the shell broken away, so as to
show the point of the iron in section.

page_text: Figure 2 is a vertical section of the same when open.
Figure 3 is a view of the bottom part seen from above.
Figure 4 is a back view; and
Figure 5 a cross section.
On a flat hollow base a is seated an upper part or shell b hinged to the former
whereby it is capable of being turned or pivotted on a bolt d passing through eyes
in two lugs cast on the base a. The said upper part b is formed of a bell-shaped
shell and provided with a suitable handle; and the openings e in the shell through
which the bolt or pivot d passes are flattened or made oval so as to give a certain
amount of play to the said upper part b and allow it to slide to and fro on the
base a; and as the base is slightly the larger, the top in the closed state will not
rest upon the outer margin of the base a, but upon the studs which are trapezoidal
in shape and taper upwards, arranged at regular intervals apart and at a regular
distance away from the outside rim of this part and surround the interior heating
space so as to prevent the fuel from falling out, without hindering the free access
of air. Thus the glowing block of fuel lies, open on all sides, in the body of the
iron, so that the air can reach it freely, being heated by contact with the hot studs
and walls of the box-iron. This arrangement is of value for the enhancement of
the heating power; and the more so because the fuel placed in the point of the
box-iron is freely played upon by the air and brought to a glowing heat, at the
point where heat is most wanted; whereas in the ordinary box-irons, this is the part
where the least heat is developed owing to the lack of an efficient air supply;
wherefore such box-irons are comparatively cold at the point. Openings e in the
upper shell give free vent to the hot air.
The open channel or space between the wall of the base a and the prismoidal
studs serves as an ash-pan and provide so large an area for that purpose that the
improved box-iron may be in use for several hours, without the ash-pan becoming
so choked with ashes as to interfere with the air-supply and necessitate emptying.
The floor of the same is formed to slope inwards all round (Figure 5) to facilitate
the removal of the ashes, which when the iron is closed, can readily be effected by
laying the iron down on its side. Further also this arrangement has the advantage
of preventing, even with the most unskilful handling, all risk of the linen etc. being
soiled in the laundry by the falling out of small cinders ashes and dust; a defect
which can never be entirely got rid of under the old arrangement of air-holes
above the sole of the iron. Moreover the bosses on the floor of the improved box-
iron are so arranged that those ranged towards the outside of the central heating
space are higher than those ranged nearer the centre; for which reason the heated
fuel stands askew with an inward inclination which obviates all difficulty in closing
the iron. At the same time the bell-shaped shell 6 of the upper part when closed
down on the outer edge of the studs f tends to press any loose particles of glowing
fuel inwards.
h
On the bottom surface of the central heating space, also a curvilinear rib
encloses a hollow or basin I which for heating purposes serves to hold spirit while
the perforated bed-plate / may be utilized to receive the fuel, its front edge being
slipped under the pivot d of the bell-shaped top and the handle being laid on the
point of the base a (Figure 2). In this way the heating of the box-iron can be
attended to with certainty and celerity, without further trouble.
The base or body a of the box-iron is provided with a sharp cone-shaped point
and is rounded off at the edge behind for use as a glazing-iron.
As a closing-device to secure the connection of the bell-shaped top with the
base or body a a lever-handle i is arranged to turn on a pivot fixed to the back of
the base a; this lever-handle slides on a wedge-shaped block k fixed to the back
plate of the top causing a forward displacement whereby the nose n is made to
engage in a notch on the base a establishing the firm connection of the parts, so as
to prevent the lifting or turning back of the bell-shaped top b. This is therefore a
double-action closing device.

page_text: 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. A hollow box-iron for charcoal and other solid glowing fuel wherein upon a
flat base (a) is arranged an upper part (6) of somewhat smaller area in such manner
that between the two an open channel or space is formed serving as an air-supply
passage and ash-tray.
2. In a hollow box-iron the arrangement of studs such as fon which the upper
part (b) rests the studs surrounding and limiting the central heating space so as
to prevent the fuel from falling out without hindering the free access of air
substantially as described.
3. In a hollow box-iron tlie upper part (6) in the shape of a dome or bell
diminishing forwards to a point n projecting in such manner as to slip into and
engage with the corresponding pointed front of the base a when in use and thereby
secured and held fast to the base substantially as described and illustrated in the
accompanying drawings.
4. In a hollow box-iron the arrangement of a rimmed pan or basin (g) for the
reception and burning of spirit or other combustible liquid an arrangement which
in combination with the perforated bed-plate (4) introduced below the hinge-
bolt (d) of the dome-shaped top serves to heat the charcoal or other solid fuel to a
red heat or glowing state in the body of the box-iron itself substantially as
described.
5. In a hollow box-iron the arrangement of a double-action closing device
consisting of a lever-handle (i) mounted on the back wall of the base a of the
box-iron in such manner as to turn to and fro in contact with a wedge-shaped
plate () at the back of the upper part (6) so as to strengthen the connection
between the two parts (a and b) and at the same time causing a forward displace-
ment of the dome or bell-shaped upper part whereby the nose is made to engage
in a notch in the base a substantially as described and illustrated in the
accompanying drawings.
Dated this 14th day of July 1894.
