Improvements in Stoves for Heating Purposes.
I, WILLIAM YOULTEN, of 159, Victoria Street, Westminster, in the County of
London, Architect, do hereby declare the nature of this invention to be as
follows:
The object of this invention is to provide a stove which shall efficiently heat an
apartment by the consumption either of gas, or of coal, wood or other fuel, as
may prove most desirable, haying regard to the circumstances attending its use
for warming purposes, e.g. the temperature or length of time on any given day or
night during which it may be desired to keep the fire burning.
To effect this object, I construct the stove, which may be of any desired shape,
in such a way that it may be readily rotated about a vertical axis, by means of
suitably placed top and bottom pivots, as hereinafter described.
According to this invention, I construct the stove substantially as follows:-
On a suitable base plate, I mount the stove so as to revolve about a vertical
axis, by providing strong top and bottom pivots. The bottom pivot, fitted in the
base plate, I make hemispherical in shape at top, so as to work in a strong cup
socket. The top pivot enters a soot guard plate (horizontally covering the chimney
opening) except for an aperture therein which affords a communication with the
Hue from either the gas or coal grate hereinafter referred to.
The surroundings of the pivot are protected by a socket cover screwed over
the top of the pivot to the upper surface of the soot guard plate.
The stove is divided into two grates, as hereinafter described-one of the grates
being intended for coal or other fuel-and the other for gas.
The gas supply is preferably taken over or under the hearth to a place adjoin-
ing the pivot. It is then conveyed to an aperture in the latter, and through a
hole in the circular socket to the supply pipe for the gas stove, thus providing a
direct service to the gas stove burners, when the gas stove faces the room.
I provide means for utilising the gas supply for igniting the coal or other
fuel in the coal grate. This I effect by providing a second hole on the same line
of diameter of the socket, so that when the coal fire grate faces the room the
aperture through the pivot above mentioned conveys the gas through the said
second hole to the supply pipe of the Bunsen burner or burners for the fire
lighter. I place the burner or burners of the fire lighter close under the bar or
bars of the grate, with margins so that dust or dirt may not be liable to enter
the said burners.
Communication between the two grates and the flue is automatically effected or
prevented by providing in the soot guard plate aforesaid an aperture of a size
sufficient to enable the smoke from the coal fire or the fumes from the gas stove
to ascend into the flue. In the top pivot plate, which is secured to the upper
part of the revolving portion of the stove, two apertures are formed, correspond-
ing in size and form to that above referred to as existing in the soot guard plate.
These two apertures are respectively placed directly over the coal grate and

page_text: the gas fire. Thus when the former faces the room, the smoke aperture in the
top pivot plate is immediately under the aperture in the soot guard plate, thereby
affording a direct communication for the smoke to ascend into the fiue, while the
aperture for the emission of fumes from the gas grate is beneath the soot guard
cover, thereby preventing any communication between the gas stove and the flue,
and consequently preventing a fall of soot or mortar into the gas stove.
When
the positions of the stoves are reversed, the apertures above them are likewise
reversed.
In order to prevent heat from the gas fire igniting the coal in the coal grate,
when this latter is not in use, I provide a fire clay partition, between the two
stoves, in the centre of which partition is a hollow space, which may be filled
in with a thickness of asbestos or other material which is a non-conductor of heat.
I may provide segmental sliding divisions working adjacent to the periphery
of the rotating portion of the stove, to act as blowers.
I hinge the cheeks of the stove, and form rebates between them and the
rotating portion of the stove, so that no draught may pass round the stove.
These hinged cheeks may also be employed as screens, when desired, by swing-
ing them outwards into the room. Even in this case no draught will pass, as
the soot guard plate prevents it.
I prefer to make the grate for coal or other fuel larger and deeper than that
for the gas fire.
By a few modifications of the details above described, the stove can be as con-
veniently applied to the close or continental stove, which usually stands wholly
or partially clear of the chimney opening or fire place.

I, WILLIAM YOULTEN, of 159, Victoria Street, Westminster, in the County of
London, Architect, 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:.
The object of this invention is to provide a stove which shall efficiently heat
an apartment by the consumption either of gas or of coal, wood or other fuel, as
may prove most desirable, having regard to the circumstances attending its use
for warming purposes, e.g. the temperature or length of time on any given day
or night during which it may be desired to keep the fire burning.
To effect this object, I construct the stove, which may be of any desired shape,
in such a way that it may be readily rotated about a vertical axis, by means of
suitably placed top and bottom pivots, as hereinafter described.
According to this invention, I construct the stove substantially as follows:-
On a suitable base plate, I mount the stove so as to revolve about a vertical
axis by providing strong top and bottom pivots. The bottom pivot fitted in the
base plate I make hemispherical in shape at top so as to work in a strong cup
socket. The top pivot enters a soot guard plate horizontally covering the
chimney opening except for an aperture therein which affords a communication
with the flue from either the gas or coal grate hereinafter referred to.

page_text: The surroundings of the pivot are protected by a socket cover screwed over
the top of the pivot to the upper surface of the soot guard plate.
The stove is divided into two grates, as hereinafter described-one of the grates
being intended for coal or other fuel, and the other for gas.
The gas supply is preferably taken over or under the hearth to a place adjoin-
ing the pivot. it is then conveyed to an aperture in the latter; and through a
hole in the circular socket to the supply pipe for the gas stove, thus providing a
direct service to the gas stove burners, when the gas stove faces the room.
I provide means for utilizing the gas supply for igniting the coal or other
fuel in the coal grate. This 1 effect by providing a second hole on the same
line of diameter of the socket, so that when the coal fire grate faces the room
the aperture through the pivot above mentioned conveys the gas through the said
second hole to the supply pipe of the Bunsen burner or burners for the fire
lighter. 1 place the burner or burners of the fire lighter close under the bar
or bars of the grate, with margins, so that dust or dirt may not be liable to enter
the said burners.
Communication between the two grates and the flue is automatically effected
or prevented by providing in the soot guard plate aforesaid an aperture of a size
sufficient to enable the smoke from the coal fire or the fumes from the gas stove
to ascend into the flue. In the top pivot plate, which is secured to the upper
part of the revolving portion of the stove, two apertures are formed, correspond-
ing in size and form to that above referred to as existing in the soot guard plate.
These two apertures are respectively placed directly over the coal grate and the
gas fire. Thus when the former faces the room, the smoke aperture in the top
pivot plate is immediately under the aperture in the soot guard plate, thereby
affording a direct communication for the smoke to ascend into the fue, while the
aperture for the emission of fumes from the gas grate is beneath the soot guard
cover, thereby preventing any communication between the gas stove and the flue,
and consequently preventing a fall of soot or mortar into the gas stove. When
the positions of the stoves are reversed the apertures above them are likewise
reversed.
In order to prevent the heat from the gas fire igniting the coal in the coal
grate, when this latter is not in use, I provide a fire clay partition, between the
two stoves, in the centre of which partition is a hollow space, which may be
filled in with asbestos or other suitable material which is a non-conductor of heat.
I may provide segmental sliding divisions working adjacent to the periphery
of the rotating portion of the stove, to act as blowers.
I hinge the cheeks of the stove, and form rebates between them and the
rotating portion of the stove, so that no draught may pass round the stove.
These hinged cheeks may also be employed as screens, when desired, by
swinging them outwards info the room. Even in this case no draught will pass,
as the soot guard plate prevents it.
I prefer to make the grate for coal or other fuel larger and deeper than that
for the gas fire.
By a few modifications of the details above described the stove can be con-
veniently applied to the close or continental stove which usually stands wholly
or partly clear of the chimney opening or fire place.
And in order that my said invention may be better understood I will now
proceed to describe the same with reference to the drawings accompanying this
specification in which Fig. 1 shews a sectional elevation of a stove constructed
according to my invention. Figs. 2 to 6 are plans of details of the same stove.
The same letters denote the same parts in all the views.
On a suitable base plate a I mount the stove so as to revolve about a vertical
axis, by providing strong bottom and top pivots b and c. The bottom pivot b,
fitted in the base plate a, I make hemispherical in shape at top, so as to work
in a strong cup socket d. The top pivot c enters a soot guard plate e (horizon-

page_text: tally covering the chimney opening except for an aperture therein which afford
a communication with the flue g from either the gas or coal grate as hereinafter
referred to).
The surroundings of the pivot ce are protected by a socket cover f screwed over
the top of the pivot e through to the upper surface of the soot guard plate c.
The stove is divided into two grates h and i, one of the grates being intended
for coal or other fuel, and the other i for gas.
The gas supply is taken preferably over or under the hearth to a point adjoin-
ing the pivot ; it is then conveyed to an aperture m in the latter. When the
stove is in the position shewn at Fig. 1, where it is represented as it would
appear when the grate for coal or other fuel is facing the room, the aperture m
comes opposite a hole k in the circular socket d, which hole k communicates with
the pipe leading to the Bunsen burner or burners intended for lighting the
coal or other fuel in the grate h. These burners are close under the bar or
bars o of the grate, the bars projecting sufficiently on either side of the burners
to prevent dust or ash from entering such burners. z shews another hole in the
circular socket d. When the stove is rotated, so that the gas fire faces the room,
this hole comes opposite the aperture m. Thus gas is supplied to the burners
of the gas fire. is the bottom plate of the revolving stove.
If desired the fire lighter may be omitted.
Communication between the two grates and the flue is automatically effected or
prevented by providing in the soot guard plate e an aperture 2 of a size suffi-
cient to enable the smoke from the coal fire or the fumes from the gas stove
to ascend into the flue g. In the top pivot plate q, which is secured to the upper
part of the revolving portion of the stove, two apertures are formed, and s,
corresponding in size and form to that above referred to in the soot guard plate e.
These two apertures are respectively placed directly over the coal grate and the
gas fire. Thus when the former faces the room, the smoke aperture in the
top pivot plate q is immediately under the aperture p in the soot guard plate e,
thereby affording a direct communication for the smoke to ascend into the flue g,
whilst the aperture s for the emission of fumes from the gas grate is beneath the
soot guard plate e, thus preventing any communication between the gas stove and
the flue, and consequently preventing a fall of soot or mortar into the gas stove.
When the positions of the stoves are reversed, the apertures above them are like-
wise reversed.
In order to prevent heat from the gas fire igniting the coal in the coal grate,
when this latter is not in use, I provide a fire clay partition t between the two
stoves, in the centre of which partition is a hollow space, which may be filled
in with a thickness of asbestos or other material which is a non-conductor of heat.
I may provide sliding screens which draw out of the wall to enclose the stove
and act as blowers when required. These screens are not shewn on the drawings.
I hinge the cheeks of the stove, and form rebates between them and the
rotating portion of the stove, so that no draught may pass round the stove. These
hinged checks u may also be employed as screens, when desired, by swinging them
outwards into the room. Even in this case no draught will pass, as the soot
guard plate prevents it.
I prefer to make the grate for coal or other fuel larger and deeper than that
for the gas fire.
By a few modifications of the details above described the stove can be as
conveniently fitted in a casing to form a close stove, which usually stands wholly
or partially clear of the chimney opening or fire place.
Figs. 7 and 8. shew my invention applied to a stove of this description,
Figure 7 shews a vertical section and Fig. 8 a sectional plan.
In this case the whole of the stove rotates on pivots b and c. is a water
chamber provided with apertures 2 for the escape of steam. 3 are columns for

page_text: supporting the upper portion of the stove. The gas connection is not shewn on
Fig. 7 being similar to that already described with reference to Fig. 1.
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:-
In stoves for heating purposes, the particular construction and combination of
parts, hereinbefore described with or without the fire lighter for the coal fire for
the purposes set forth.
