PROVISIONAL SPECIFICATION.
Improvements in or connected with Ovens or Stoves.
We, HARRIS WOOD of Shepley near Huddersfield, Yorkshire, Builder and
PAUL DAWSON of New Mill near Huddersfield aforesaid Builder do hereby
declare the nature of this invention to be as follows:-
This invention refers to ovens or stoves used for heating tailors' irons, warming
rooms, cooking and like purposes, and consists in an improved construction and
arrangement of same whereby a higher temperature can be obtained and maintained
for any reasonable period of time without adding to the amount of fuel heretofore
consumed, and with less attention being paid thereto.
In carrying out our invention we enclose or build up the oven and fire place
in brick setting, or in a suitable metal shell or casing, the same if desired, being
covered or lined with non-conducting composition or material for preventing
radiation of heat from the stove. On two or more sides of the stove or fire place
and in the setting or casing we make or form two or more series of air passages,
those in each series communicating with one another in such manner as to conduct
currents of air backward and forward through the several passages from the lowest
to the highest of the series which communicates with the fire place at a point
directly under the oven. Atmospheric air is admitted to the lowest air passage of
each series through openings in the front or other suitable part of the stove and as
it circulates upwards or backwards and forwards through the air passages it is
heated to a high temperature ere it passes into the fire place. The admission or
distribution of currents of hot air over the fire ensures more perfect combustion,
dispenses dense smoke, and considerably increases the heat of the fire without any
additional consumption of fuel. When made up with coke, the fire will burn
brightly for a much longer period without requiring attention than is possible with
the present construction of stove, and if the air supply be shut off or regulated
accordingly, each day on leaving work the fire will burn through the night and
keep the oven heated ready for immediate use in the morning. For heating tailors'
irons in large clothing concerns, the above construction of stove is especially
advantageous as the time now wasted in lighting the fires and heating the oven
may be put to better use. The hot air before passing into the fire may be circulated
around two or more sides of the oven. For warming rooms or heating water, a
boiler is substituted for the oven. The fire bars are made separate and can be
drawn out one at a time for cleaning the fire. A moveable pau or cistern con-
taining cold water is placed under the fire bars to receive the hot clinkers and
ashes from the fire, the steam or vapour arising therefrom passing through the fire
and being consumed.
The air inlets, the fire place door, and the cistern above the water level, are or
may be provided with regulators or ventilators to shut off or admit and regulate
the admission of air to the air passages or to the fire, and the flue is likewise
provided with a damper.

page_text: Improvements in or connected with Ovens or Stoves.
We, HARRIS WOOD, of Shepley, near Huddersfield, Yorkshire, Builder, and
PAUL DAWSON, of New Mill, near Huddersfield, aforesaid, Builder, 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 refers to ovens or stoves used for heating sad irons in clothing
factories or laundries, warming rooms, cooking and like purposes, and consists of
an improved construction and arrangement of same whereby a higher temperature
can be obtained and maintained for any reasonable period of time without adding
to the amount of fuel heretofore consumed, and with less attention being paid
thereto.
In carrying out our invention we enclose or build up the oven and fire place in brick
setting, or in a suitable metal shell or casing, the same, if desired, being covered
or lined with non-conducting composition or material for preventing radiation of
heat from the stove. On two or more sides of the stove or fire place and in the
setting or casing we make or form two or more series of air passages, those in
each series communicating with one another in such manner as to conduct currents
of air backward and forward through the several passages from the lowest to the
highest of the series which communicates with the fire place at a point directly
under the oven.
Atmospheric air is admitted to the lowest air passage of each series through
openings in the front or other suitable part of the stove and as it circulates
upward, or backward and forward through the air passages, it is heated to a high
temperature ere it passes into the fire place, whereby perfect combustion is obtained,
the temperature of the stove raised without additional fuel, and the emission of
dense smoke from the flue avoided.
For the purpose of fully describing and ascertaining our said invention, reference
is herein had to the annexed drawings forming a part of this Specification, in
which:-
Fig. 1 is front elevation, shewn partly in section taken on line A, A, of Fig. 2,
of an oven or stove embodying our invention;
Figs. 2 and 3 are transverse sections taken respectively on lines B, B, and C, C,
of Fig. 1;
and
Fig. 4 is plan of Fig. 1 with the hot plate and uptake or chimney removed;
Fig. 5 is a detail hereafter referred to.
Referring to the drawings, a is the brick setting of the stove, 6 the chimney or
uptake to same provided with damper 6', c the oven (or boiler) having doors c for
sealing same; e is the fire place under the oven and e¹ the fire or grate bars which
are each supported loosely in cross rails or bridges 2 and can be drawn out one
at a time for cleaning the fire; f is the opening to give access to the fire place
for feeding fuel thereto and for other purposes, such opening being closed by
doors adapted to be slided endwise in ways in the frame 2, and 9 is the ashes
pan or tray constructed so as to hold water and when pushed home to close the
ashes pit or opening under the fire place. The stove is braced or bound firmly
together by vertical angular corner plates hand side plates h', bolted at their
upper ends to the brickwork and having their lower ends let into the floor, or
bolted thereto or to the brickwork, as may be found most suitable and convenient.
If the stove is not erected against a wall as that shewn in the drawings is supposed
to be, an angular plate his bolted to each corner thereof. Across the front and
also, if desired, across the back and ends of the stove are placed horizontal plates

page_text: or straps which may be bolted to the corner plates or fitted into sockets ½³ cast
therein, as shewn clearly in Fig. 5.
In addition to firmly binding the stove, the aforesaid corner and cross plates.
are advantageous in facilitating conveyance and erection of our improved stoves.
On the top of the stove we place a hot plate i which serves to warm or keep
warm any article or object which may be placed thereon.
In the brick setting near to each side of the fire place so as to be heated by
the fire are formed two or more series of air channels or passages k, k, those in
each series being arranged one above another from front to back of the fire place
and communicating with each other at alternate ends so as to give a circulation
backward and forward through the several passages from the lowest to the highest
of the series.
The upper channel or passage of each series communicates by passage k¹, formed
at right angles thereto, with the upper end of the fire place near the front thereof,
whilst the lowest channel or passage of each series is open to the atmosphere and
is protected by a plate such as 7 suspended on a stud on which it can be moved
by means of handle varying distances to and from the inlet end of the air
passages so as to regulate and control the admission of atmospheric air thereto;
or in lieu of said plate, an ordinary perforated disc movable around a fixed
perforated grate may be employed for the same purpose.
Atmospherie air admitted to the lower air passages or channels is caused to
circulate in a zigzag or backward and forward direction upward through each
passage K, K, as indicated by arrows and in its course is heated to a high tempera-
ture by contact with the surrounding heated brickwork and heat radiating therefrom
ere it makes its exit into the fire place.
The outlets K', K', being situated near the top of the fire place direct and
distribute the currents of hot air from the air circulating passages over the fire
where they immediately mix with the smoke and heavy gases given off and supply
the requisite elements to produce perfect combustion, all the gases and smoke
being thereby consumed and the heat of the stove considerably increased without
any additional consumption of fuel.
The products of combustion pass out of the fire place through openings or
flues m, m, into a chamber m' at the back of the oven from whence they escape
direct to the chimney or uptake as indicated. The said openings m, m, are
arranged at the rear of the fire place and a little above the hot air inlets k', k¹,
so that the smoke and heavy gases will be intercepted by the currents of hot air
before they can escape out of the fire place.
Access is had to the chamber m¹ and flues m, m, from each side of the stove
by opening the sliding doors n, n.
When made up with coke and the doors f¹ and ashes pau y are closed, and the
damper b' regulated to suit requirements, the fire will burn brightly for a much
longer period without requiring attention than is possible with the present con-
struction of stoves, and if the air supply be shut off or regulated accordingly,
each day on leaving work, the fire will burn through the night and keep the oven
heated ready for immediate use in the morning.
For heating sad irons in large clothing concerns or laundries, the above con-
struction of stove is especially advantageous as in addition to the greater heat
obtained and the economy of fuel, the time now wasted in lighting the fires may
be otherwise utilised.
The hot air before passing into the fire place may, if desired, be circulated
around two or more sides of the oven.
For warming rooms or heating water a boiler is substituted for the oven.
The steam or vapour arising from the immersion of the hot clinkers and ashes
which fall out of the fire into the pan g passes through the fire and is consumed.
The said pan above the water level may be provided with a regulator or
ventilator to shut off or admit and regulate the admission of air to the ashes
place.

page_text: Holes are formed in the bottom of the frame f2 as shewn at f in Fig. 3 in
order that dust and particles of fuel dropped into same will fall on to the floor
instead of accumulating in the groove and obstructing the movement of the sliding
doors f¹.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is
Firstly. The method of and means for heating atmospheric air and distributing
same over the fire in ovens or stoves for heating, cooking, boiling or like purposes,
substantially as herein shewn and described and for purposes set forth.
Secondly. The general arrangement and construction of ovens or stoves having
passages or channels for circulating and heating atmospheric air and distributing
it over the fire to promote perfect combustion, substantially as berein shewn and
described.
