Improvements in Stoves.
I, JOHN JAMES ROYLE of Dalham Engineering Works, Great Bridgewater
Strect, Manchester, Engineer, do hereby declare the nature of my said invention
to be as follows:-
This invention refers to that class of stove which burns a prepared carbonaceous
fuel composed of charcoal or other carbonaceous matter highly compressed and
which is free from smoke and objectionable fumes and my invention has for its
object the manufacture of such stove in a manner that will ensure of more convenient
feeding and cleaning and render the stove more generally useful and convenient as
hereinafter described.
In accordance with my invention and in an arrangement of stove for use in
ventilated apartments where the products of combustion may be allowed to mingle
with the atmosphere, I employ a fire box or inner casing closed with a tightly
fitting lid. A grate is arranged about the middle of the fire box, supplied with air,
by preference through a pipe rising from the bottom of the fire box and opening
under the grate, the ash being prevented falling down the tube by a
depending from the grate. The lid of this fire box is locked by a bayonet fastening
and is arranged with lugs for receiving a handle by which the entire fire box may
be placed inside an outer and more ornamental casing.
The annular space between the fire box and outer casing forms an air flue.
bell
I have found this construction effective as a heating stove and very convenient
to manipulate in stoking and cleaning out without dirt. A vaporising dish or hot
water kettle may be fitted to the lid to render the atmosphere humid or afford
a supply of hot water. An opening is in the lid fitted with a regulating device to
regulate the rate of combustion.
In an arrangement of stove for use in apartments such as bedrooms when the
products of combustion must be conveyed out of the room I make the outer and
more ornamental casing airtight by fitting a cover with an asbestos or other joint
in the lid. Inside the casing is a fire basket fitted with grate and air supply pipe
opening under the grate, and said fire basket is fitted with lugs or a cross bar so
that it can be readily lifted out of the casing. The lid or cover is also fitted with
lugs so that a handle common to both may be used for carrying purposes.
At a convenient height a nozzle is fitted to the casing with a flue or pipe to
convey the products of combustion to the nearest flue or chimney or out of the
apartment, and said pipe may be telescopic.
In an arrangement of stove in which the burning fuel is visible, I provide mica
openings whereby a more cheerful effect is obtained. In this stove the ornamental
casing is formed air tight as in the last modification so that the products of
combustion may be collected and conveyed away. A suitable flue pipe and door
is fitted in the front of the store glazed with sheet mica and which may be either
hinged after the manner of an ordinary fire door or as I prefer may be made to
turn upon its lower horizontal edge by having a fire box attached to its lower
portion and projecting inside the stove casing so as to give the door a preponderance.

is fitted with a grate which receives its air supply through openings in the front
The door is provided with a handle so that the entire door and fire box

with fuel.
The outer and more ornamental portion of these stoves may be formed of cast
or sheet metal or of stoneware or earthenware and may be greatly varied in
form and design. A modified form of the fire box first mentioned may be used for
heating green-houses.
The fire box may be made self feeding by fitting it with a feed tube closed
at the top and down which the fuel may descend on to the grate as it is consumed.

I, JOHN JAMES ROYLE, of Dalham Engineering Works, Great Bridgewater
Street, Manchester, Engineer, do hereby declare the nature of my said invention
and in what manner the same is to be performed, to be particularly described aud
ascertained in and by the following statement :-
This invention refers to that class of stove which burns a prepared carbonaceous
fuel composed of charcoal or other carbonaceous matter, compressed into cakes or
blocks and which is free from smoke and objectionable fumes, and my invention has
for its object the manufacture of such stove in a manner that will ensure of more
convenient feeding and cleaning and render the stove more generally useful and
convenient as hereinafter described.
And in order that my said invention shall be the more readily understood and
carried into practical effect I have hereunto annexed three sheets of drawings and
will now proceed to describe the same with the assistance of the various figures
and letters of reference marked thereon.
On Sheet 1 Fig. 1 is an elevation partly in section, Fig. 2 a plan-also partly in
section and Figs. 3 and 4 side and plan views respectively of the fire box detached,
of a form of stove suitable for ventilated apartments.
On Sheet 2, Fig. 5 shews a vertical section and Fig. 6 a detached view of the
fire box of a stove provided with ventilating flue for burning in bedrooms and
rooms deficient in ventilation.
On Sheet 3, Fig. 7 shews a side view partly in section, Fig. 8 a front exterior
view and Fig. 9 a perspective view of the fire box detached, of a stove designed to
shew the fire burning and for general use.
Referring now to Sheet 1. In accordance with my invention and in an arrange-
ment of stove for use in ventilated apartments where the products of combustion
may be allowed to mingle with the atmosphere, I employ a fire box or inner
casing (A) closed with a tightly fitting lid (B).
A grate (C) is arranged about the middle of the fire box, supplied with air, by
preference through a pipe (D) rising from the bottom of the fire box (A) and
opening under the grate (C) the ash being prevented falling down the tube (D) by
a "bell" depending from the grate (C). The lid (B) of this fire box is locked
by a bayonet fastening and is arranged with lugs (G) for receiving a handle (H)
by which the entire fire box may be placed inside an outer and more ornamental
casing (I) fitted with an ornamental and perforated cover (I¹).
The annular space (J) between the fire box and the outer casing aforesaid form
an air flue through which the air freely circulates as shewn by the arrows, being
warmed in its passage through the annular space (J).
I have found this construction effective as a heating stove and very convenient
to manipulate in stoking and cleaning out without dirt as the entire fire box (A)

forth.
2nd. The improved store shewn on Sheet Two of the accompanying drawings
for use in apartments deficient in ventilation and consisting of a detachable fire
box (A) located within an outer casing (I) provided with air tight lid (N)
and ventilating pipe (S) attached to regulating nozzle (R) substantially as set
forth.
3rd. The improved "visible fire stove "shewn on Sheet Three of the accompanying
drawings consisting of an outer casing (I) a detachable fire box (X) attached to
a fire door fitted with mica front (U), the regulating nozzle (R) and vent pipe (S)
substantially as set forth.

page_text: can be lifted out of the casing and carried out of the apartment for replenishing or
removing the ash which falls to the bottom of the fire box under the grate (C) as
illustrated. I have found this to be a most desirable feature in stoves of this
class and much better than the prevailing practice of cleaning the stoves in the
apartment through a drawer or opening at the bottom.
A vaporising dish (K) or hot water kettle may be fitted to the lid to render the
atmosphere bumid or afford a supply of hot water. An opening (L) is made in
the lid (B) fitted with a regulating shutter (M) to regulate the rate of combustion
which can be done to the greatest nicety by covering the opening (L) more or less
by the shutter (M).
The products of combustion in this stove escape into the atmosphere and pass
away with the hot air current. This class of stove is only intended to be used in
rooms with adequate ventilation.
Referring now to Sheet 2 which illustrates an arrangement of stove for use in
apartments such as bedrooms where the products of combustion must be conveyed
out of the room,
I make the outer and more ornamental casing (1) air tight, by
fitting it with a cover (N) having an asbestos or other joint (0) in the lid.
Inside the casing is a fire basket (A), fitted with grate (C) and air supply
pipe (D), opening under the grate, and said fire basket is fitted with lugs or
a cross bar (P) so that it can be readily lifted out of the casing. The lid or
cover is also fitted with lugs (Q) so that a handle (H) common to both may
be used for carrying purposes.
At a convenient height a nozzle (R) is fitted to the casing with a pipe (S)
to convey the products of combustion to the nearest flue or chimney or out of
the apartment, and said pipe may with advantage be telescopic.
A shutter or regulator (T) is fitted to the nozzle to control the draught
by opening or closing which the combustion may be regulated to the greatest
nicety.
It will be observed that the bottom of the ornamental casing in the stove is
closed with the exception of a central opening immediately under the air inlet
tube (D):
Referring now to Sheet 3, which illustrates an arrangement of stove in which
the burning fuel is visible,-I provide a mica glazed opening (U) whereby a more
cheerful effect is obtained. In this stove the ornamental casing (I) is formed oval
in plan and air tight as in the last modification so that the product of combustion
may be collected and conveyed away by a telescopic ventilating pipe (S) fitted to
the nozzle (R). A suitable door (V) is fitted in the front of the stove casing
glazed with sheet mica (U) and which may be either hinged after the manner of
an ordinary fire door, or as I prefer, may be made to turn upon its lower horizontal
edge (W) by having a fire box (X) attached to its lower portion and projecting
inside the stove casing so as to give the door a preponderance of weight on the
inside whereby it is kept closed in a natural way by turning upon the lower edge (W)
as a centre. The fire box is fitted with a grate at (Y) which receives its air supply
through openings (Z) in the door front. The door is provided with a handle (Z)
so that the entire door and fire box can either be drawn forward rotating upon the
edge (W) or may be lifted from the stove and carried away for cleaning out or
replenishing with fuel. The fire box is shewn removed in Fig. 9.
The outer and more ornamental portion of these stoves may be formed of cast
or sheet metal, or of stone or earthenware and may be greatly varied in form
and design.
Having thus particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
