I, ERNEST CADE, of 60, Quai de la Rapeé, Paris, France, Coal Merchant, do hereby
declare the nature of this invention to be as follows:-
This Invention relates to improved arrangements for burning fuel in domestic and
other heating apparatus.
According thereto a grate is constructed with two vertically arranged louvre like
sets of bars arranged between two side plates or cheeks.
The fire place or furnace thus arranged rectangularly presents a large mass of fuel
in a state of ignition, a radiating surface, and affords very ample access of air,
whilst facilitating the ignition and the management of the fire.
Referring to the annexed sheet of illustrative drawings Figures 1 and 2 show
respectively in vertical section through the centre, and in cross-section, an application
of the improved grate in a domestic stove.
The hopper A closed by a moveable cover G which is capable of holding water,
receives the fuel which sinks into the grate B formed by the two plates or checks C, C¹
and the movable bars b, b, b arranged similarly to the slats of Venetian blinds.
These bars project at their ends beyond the plates or cheeks or they may rest simply
at their extremities upon projections s, s¹ formed so as to allow of the bars being
removed from the front.
In Fig. 1, the bars are shown resting on projections, and in Fig. 2, they are
shown projecting beyond the side plates or cheeks of the furnace.
Two ribs m on the inside face of each plate or cheek, carry a drawer or carriage D
that is designed to facilitate the lighting of the fire.
This drawer is formed with two side plates u, u, connected by two fixed bars b¹, 81
and with a bar b¹¹ moveable like the bars b.
The bottom of the drawer is closed in by a pivotted plate d capable of movement
about the pins n n. The plate d is balanced by means of a counterweight 1 the arm of
which can be turned back till it touches the stop ..
Underneath the drawer D is the ashpan E.

page_text: Each of the internal side faces of the grate or fire place is provided with grooves i, i,
in which can slide a shovel like plate I furnished with a handle.
Ignition is effected in the drawer which is partially drawn out for the purpose and
then returned.
During the progress of combustion ashes and clinker are separated from the upper
fuel by means of the shovel I, and are allowed to fall into the ash pan by tipping the
plate d.
For a stove having a flue designed to project through a plate or wall into a chimney
uptake or flue I provide for automatic closing of the hole in the plate or'wall on with-
drawal of the flue attached to the stove by means of a plate or valve H operated by a
counterweight_h. Thus back-draught and escape of deleterious gases from the
chimney into the room are obviated....
F
The front of the casing, of the stove that encloses the grate is left open so as to
allow of the enjoyment of the radiant heat, and of the sight of the fire, as well as to
facilitate poking. A shade or guard R shown in dotted lines may be fixed in front of
the ashpan and grate being hooked on at r. A joint to be roasted or a kettle or pan
may be placed there; but in that case the bottom and the sides of the guard will admit
of the passage of air in sufficient quantity for combustion, also of a poker or stoking
iron.
The bars bb of the grate may be held by means of the arrangement shown in
Figs. 3 and 4.
For this purpose the frames C fitted against the internal faces of the plates or cheeks
of the grate or furnace keep in place the bevelled or wedge-shaped plate C₁ (Fig. 4)
which is provided with notches for the reception of the bars b, b.
The grate can thus be very easily cleaned, for it is only necessary to remove the
frames C in order to take the grate apart almost instantaneously.
In order to facilitate the descent of the clinker into the ashpan, the bars b bare
made movable at will by means of the arrangement shown in Figs. 5 and.6.
The bars bare-in this arrangement each provided with two necks or journals c, c¹,
fitting in the notches of the plates or cheeks of the grate or furnace. Each neck or
journal c¹ is furnished with a sort of crank arm c¹¹. The regulator bar K is caused
by means of the projection o of a lever or by an eccentric to move up and down,
and thereby act by means of its notches upon the crank arms c¹l c¹¹,
the bars b, b, after the manner of the slats of a Venetian blind.

page_text: Improvements in Heating Apparatus for Domestic and other
Purposes.
I, ERNEST CADE, of 60 Quai de la Rapeé, Paris, France, Coal Merchant, 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 improved arrangements for burning fuel in domestic and
other heating apparatus.
According thereto a grate is constructed with two vertically arranged louvre like
sets of bars arranged between two side plates or cheeks.
The fire place or furnace thus arranged rectangularly presents a large mass of fuel
in a state of ignition; a radiating surface; and affords very ample access of air,
whilst facilitating the ignition and the management of the fire.
Referring to the sheet of illustrative drawings filed with my provisional specifi-
cation
Figs. 1 & 2 show respectively in vertical section through the centre, and in cross-
section, an application of the improved grate in a domestic stove.
The hopper A closed by a movable cover G which is capable of holding water,
receives the fuel which sinks into the grate B formed by the two plates or cheeks C, Ci
and the movable bars b, b, b arranged similarly to the slats of venetian blinds.
These bars project at their ends beyond the plates or cheeks or they may rest
simply at their extremities upon projections s, & formed so as to allow of the bars
being removed from the front.
In Fig. 1, the bars are shown resting on projections, and in Fig. 2 they are shown
projecting beyond the side plates or cheeks of the furnace.
Two rails m on the inside face of each plate or cheek, carry a drawer or carriage D
that is designed to facilitate the lighting of the fire.
This drawer is formed with two side plates u, u, connected by two fixed bars b¹, 61
and with a bar 611 novable like the bars b.
The bottom of the drawer is closed in by a pivotted plate d capable of movement
about the pins n n. The plate d is balanced by means of a counterweight / the arm
of which can be turned back till it touches the stop .
Underneath the drawer D is the ashpan E.
Each of the internal side faces of the grate or fire place is provided with grooves i, i,
in which can slide a shovel like plate I furnished with a handle.
Ignition is effected in the drawer which is partially drawn out for the purpose and
then returned.
During the progress of combustion ashes and clinker are separated from the upper
fuel by means of the shovel I, and are allowed to fall into the ash pan by tipping the
plate d.

page_text: For a stove having a flue designed to project through a plate or wall into a chimney
uptake or flue I provide for automatic closing of the hole in the plate or wall on
withdrawal of the flue attached to the stove by means of a plate or valve H operated
by a counterweight h. Thus back-draught and escape of deleterious gases from the
chimney into the room are obviated.
The front of the casing of the stove that encloses the grate is left open so as to
allow of the enjoyment of the radiant heat and of the sight of the fire, as well as
to facilitate poking.
.
A shade or guard R shown in dotted lines may be fixed in front of the ashpan and
grate being hooked on at 7.
A joint to be roasted or a kettle or pan may be placed there; but in that case the
bottom and the sides of the guard will admit of the passage of air in sufficient quantity
for combustion, also of a poker or stoking iron.
The bars b, b, of the grate may be held by means of the arrangement shown in
Figs. 3 & 4.
For this purpose the frames C fitted against the internal faces of the plates or
cheeks of the grate or furnace keep in place the bevelled or wedge-shaped plate C'
(Fig. 4) which is provided with notches for the reception of the bars b, b.
The grate can thus be very easily cleaned, for it is only necessary to remove the
frames C in order to take the grate apart almost instantaneously.
In order to facilitate the descent of the clinker into the ashpan, the bars b, b, are
made movable at will by means of the arrangement shown in Figs. 5 & 6.
The bars b, bare in this arrangement each provided with two necks or journals c, c²,
fitting in the notches of the plates or cheeks of the grate or furnace. Each neck or
journal e¹ is furnished with a sort of crank arm c".
The regulator bar K is caused by means of the projection o of a lever or by an
eccentric to move up and down, and thereby act by means of its notches upon the
cranks arms c¹¹, cl, cl so operating the bars b, b, after the manner of the slats of a
venetian blind.
Having now particularly described the nature of this invention, and in what
manner the same is to be performed, I declare that what I claim is :-
(1). A grate comprising two sets of movable bars a drawer with bottom that can
be tilted and provision for holding above the drawer a shovel like plate or removable
division substantially as described for the purposes indicated.
(2). The arrangement described with reference to and illustrated in Figs. 3 and 4,
for holding the bars b, b, of the grate with two sets of bars.
(3). The arrangement described with reference to and illustrated in Figs. 5 and 6
for operating the bars of the grate, comprising a regulator bar K operated by a lever
or an eccentric and whose notches act upon the crank arms c", c¹¹ projecting from the
necks or journals c¹, c' as specified.
(4). Providing in connexion with a stove such as described a flue arranged to
project through a hole in a plate or wall into a chimney uptake or flue, and a valve or
closing plate H arranged to automatically close such hole on withdrawal of the portion
of flue connected with the stove as described.

fuel by means of the shovel 1, and are allowed to fall into the ash pan by tipping the
plate d.
For a stove having a flue designed to project through a plate or wall into a chimney
uptake or flue I provide for automatic closing of the hole in the plate or wall on with-
drawal of the flue attached to the stove by means of a plate or valve H operated by a
