I ROBERT BOYLE of the firm of Robert Boyle & Son of Holborn Viaduct in the
City of London and of Glasgow in the County of Lanark North Britain Ventilating
and Sanitary Engineers do hereby declare the nature of said Invention for
IMPROVEMENTS IN STOVES FURNACES AND FIRE GRATES AND THEIR ADJUNCTS FOR
HEATING AND VENTILATING ROOMS AND FOR OTHER PURPOSES," to be as follows:-
66
The object of my Invention is to provide stoves furnaces and fire grates in which
a larger amount of effective heat is obtained from a given amount of fuel and the
heat is better distributed and utilized and a better ventilation is obtained when
required than is the case with stoves furnaces and grates as hitherto constructed-
1 make the fire place of the stove furnace or grate with the bars inclined upwards
in one or both directions or all round in a comical or other form instead of being
arranged horizontally or nearly so as has hitherto been the practice so that I obtain
a much greater area for the supply of air to the fuel from underneath the bars
and I may also interpose bars or gratings between the fire space and the cheeks or
sides of the grate, stove or furnace so as to present a still larger area of fuel to
the air which becomes highly heated as it ascends the space and before it passes
to the fuel-In stoves I prefer to arrange a deflector suspended over the fire and
to continue the flue by which the products pass to the chimney in a number of
split up or divided passages or flues or bent or angled elbows or diverted passages-
The whole is surrounded by an air casing into which external air is passed to be
heated from which casing a suitable outlet is provided for the escape of the heated
air into the rooms to be warmed, this outlet preferably taking the form of a
conduit running round the room with vertical open topped upcasts for the outlet
of heated air to some distance up into the room, these upcasts and conduit being
preferably situated closely to the walls of the room to heat the same-The openings
for the escape of the heated air are preferably provided with strainers of canvas
or other material-The stove may have gills or wing plates to present a still
further heating surface to the air, the before named split divided or diverted outlet
for the products of combustion presenting a largely increased heating area and the
deflector before named above the fire giving a very effective dispersion of the heat

nozzles or openings turned or directed in a downward direction through which hot
air is supplied on to the top of the fire for consuming or preventing smoke-The
fresh air passes to the stove preferably through a casing, or shaft beside it so as to
become heated by the stove-In the air casing around the stove may be arranged
a water trough for moistening the heated air and this trough may form a surface
for directing the air more effectively upon the heating surface of the stove-When
applied to open grates the bars are arranged at an angle as before described
descending from the back and a supply of air for the fire may be taken through a
passage at the back or sides of the grate or both, leading into a passage which may
be a hollow top bar with perforations at its inward part through which the hot
air passes in a divided and heated state downwards and inward onto the fuel-
The fresh air may be admitted to channels at the back or sides of the grate or
both passing around or partly around the base of the flue leading to the chimney
and provided with openings (preferably covered with gauze) for the direction of
the heated air upwards into the room-Gills or wing plates may be arranged in
this air space to give a larger heating surface and a baffle plate or plates may be
arranged near the entrance for air to direct it between these gills or plates. The
supply of air to the hollow top bar or passage may be directed by tubes or passages
towards the front part thereof-The arrangement of the bars as herein before
described to give au increased area for the impingement of air beneath the fuel
may be applied to grates stoves and furnaces generally.

I, ROBERT BOYLE, of the firm of Robert Boyle and Sons of Holborn Viaduct 3
in the City of London and of Glasgow in the County of Lanark, North Britain,
Ventilating and Sanitary Engineers, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:―
The object of my Invention is to provide stoves furnaces and fire-grates in which 3
a larger amount of effective heat is obtained from a given amount of fuel, and the

page_text: heat is better distributed and utilized, and a better ventilation is obtained when
required, than is the case with stoves furnaces and grates as hitherto constructed
I will first describe my Invention as applied to a close stove and afterwards I will
describe the modifications or adaptations to an open stove or ordinary grate.
Figure 1 is a vertical section of a close stove and its adjuncts arranged according
to my Invention and Figure 2 is a horizontal section of the stove. I make the
fire-place of the stove furnace or grate with the bars a inclined upwards all round
in a conical or other equivalent form as shewn clearly in the example illustrated in-
the drawing instead of being arranged horizontally or nearly so as has hitherto
been the practice so that I obtain a much greater area for the supply of air to the
fuel from underneath the bars, and I may also where the Invention is applied to an
ordinary or open fire place grate or furnace as hereinafter described interpose bars
or gratings between the fire spaces and the cheeks or sides of the grate stove or
furnace so as to present a still larger area of fuel to the air which becomes highly
heated as it ascends the space and before it passes the fuel. In stoves I prefer to
arrange a deflector b suspended or fixed over the fire space and to continue the
flue by which the products pass to the chimney in a number of split up_or
divided passages or flues or bent or angled elbows or diverted passages c³. The
whole is surrounded by an air casing à into which external air is passed to be
heated and from which casing a suitable outlet passage d' is provided for the escape
of the heated air into the rooms to be warmed this outlet preferably terminating in
the form of a conduit d³ running round the room with vertical open topped up-
casts d' for the outlet of heated air to some distance up into the room these upcasts
and conduit being preferably situated closely to the walls of the room to heat the
same. The openings for the escape of the heated air are preferably provided with
strainers of canvas or other material. The stove may have gills or wing plates e to
present an increased heating surface to the air the before named split, divided or
diverted outlet c³ for the products of combustion presenting also a largely increased
heating area, and the deflector b before named above the fire space, giving a very
effective dispersion of the heat from the fuel. Above and around the fire may be
arranged a perforated ring f with nozzles or openings turned or directed in a
downward direction into which air is admitted through any suitable inlet such as
those indicated at ƒ³ so that the air heated therein is then supplied on to the top
of the fire for consuming or preventing smoke and ensuring a proper combustion of
the fuel. The fresh air passes to the stove preferably through a casing or shaft g
beside it so as to become heated by the stove. In the air casing around the stove
may be arranged a water trough h for moistening the heated air and this trough
may form a deflector or surface for directing the air more effectively upon the
heating surfaces of the stove. Figure 3 is a front view Figure 4 a vertical section
and Figure 5 a sectional plan illustrating my Invention applied to an open fire
place or grate the bottom bars a are arranged at an angle as before described (with
respect to the stove) descending from the back and a supply of air for the fire may
be taken through a passage i at the back or sides of the grate or both, leading into
a passage the equivalent of that marked fin Figure 1 which may be a hollow top
bar f extending around or partly around the tire space and with perforations at
its inward part through which the hot air passes in a divided and heated state
downwards and inward onto the fuel substantially as described with reference to
the stove. The fresh air may be admitted to channels ; at the back or sides of the
grate or both and passing around or partly around the base of the flue k leading to
the chimney and provided with openings (preferably covered with guaze) for the
direction of the heated air upwards into the room. is a plate for directing the
air upwards. Gills or wing plates may be arranged in this air space to give an
increased heating surface and a baffle plate or plates m may be arranged near the
entrance for air to direct it between these gills or plates j³. The supply of air to
the hollow top bar or passage may be directed by tubes or passages n towards the
front part thereof.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is:
First. In fire places furnaces or stoves the arrangement of the bars or grating
in an inclined position as herein before described (as distinguished from a horizontal
or approximately horizontal position) for the purpose of presenting a larger area for
the air supply to the fuel therein the construction when applied to stoves or closed
furnaces being conical or the equivalent of conical and when applied to open or
ordinary fire places or grates being in combination with bars or gratings between
the fire space and the cheeks or sides of the fire place or grate substantially as
herein before described.
Second. In stoves a deflector or its equivalent situated over the fire space in
combination with a number of split up or divided channels or flues or angled
elbows or diverted and separate passages leading to the outlet or chimney
substantially as hereinbefore described.
Third. In stoves the combination of diverted and separate passages leading
from the fire space to the outlet or chimney and also the combination of the same
with a surrounding air heating casing substantially as herein before described.
Fourth. In combination with the subject matter of the last preceding claiming
clause, upcasts or passages opening from the air heating space of the stove into the
room or place to be warmed and discharging towards the upper part of the said
room or place substantially as hereinbefore described.
Fifth. In fire places furnaces and stoves a ring or channel situated over the fire
place and with means for admitting and heating air and for discharging it in a
downward direction onto the fuel substantially as herein before described.
Sixth. In stoves a water trough in the air heating space and arranged to act
also as an air deflector substantially as and for the purpose hereinbefore described.
Seventh. The arrangement and combination of parts constituting the air heating
or close stove hereinbefore described and illustrated in Figures 1 and 2 of the
accompanying drawings.
Eighth. The arrangement and combination of parts constituting the fire grate or
open stove hereinbefore described and illustrated in Figures 3, 4 and 5 of the
accompanying drawings.
Ninth. The combination with open fire grates of passages j with means for
admitting and directing external air and warming it by the heat of the fire in the
grate and discharging it into the room as hereinbefore described and illustrated
more particularly in Figure 4 of the accompanying drawings.
