AN IMPROVED STOVE OR FIRE-PLACE
Year: 1885

page_text: "
I, MARIE EDMOND PHILBERT CHABOCHE, of Paris, France, Engineer, do hereby
declare the nature of my invention for "AN IMPROVED STOVE OR FIRE-PLACE to
be as follows:-
This invention relates to an improved stove or fire-place which is adapted to be
moved from place to place. The said stove possesses the following advantages
amongst others viz:-Its arrangement is such that the fire is visible; its manage-
ment is easy; it is very stable; the regulation of the heat is easily effected; it is
very durable; and its shape and size enable it to be easily adapted to ordinary
fire-places.
In carrying my said invention into practice I provide a platform which carries
the stove proper, and the front portion of which serves as a cinder guard or fender.
The connection between the stove and the platform is effected by means of a
groove and tongues, or otherwise. The platform is supported by two large rollers
at the sides and a small one placed in front.
On the stove, near the platform, is arranged the ash-box which is arranged
in such a manner as to prevent the air passing through the joints around the.
ash-box. For this purpose the ash-box is suspended and its side edges slide in
two grooves. The edge of the front side of the ash-box is inclined, and in order
that this edge should constantly bear against the front of the stove, two wedge-
shaped lugs on the sides of the ash-box are adapted to impinge against two other
wedge-shaped pieces on the stove, whereby the ash-box, by its weight, forms a
tight joint. For opening the ash-box, it is sufficient to slightly lift the bandle
thereof and to draw the box outwards. The admission of air to the ash-box is
controlled by means of an ordinary diaphragm provided with a button. The rear
side of the ash-box is movable in such a manner that the ash-box can serve as a
scoop or shovel for withdrawing the cinders.
The door of the stove is pierced with holes in which are placed pieces of mica
which permit the fire to be seen.
The binge on which the door moves is not integral with the front of the stove;
but has a T-shaped extension which enters a corresponding aperture in the casing
of the stove. When this portion is inserted in the said aperture, it is only
necessary to allow it to descend in order to be firmly engaged. The upper portion
of the door is provided with an appendage permitting it to be lifted with a poker
when it is desired to open the same. The lower part of the door is hinged upon
the front of the stove. The upper edge of the lower portion of the door is formed
with two converging inclined planes, and the lower edge of the upper portion of
the door is hollowed out for receiving the angular edge of the lower portion.

page_text: The grate contains a large comb arranged above the door, a refractory lining, an
elliptically shaped set of bars, and movable grate.
The teeth of the said comb are inclined at an angle of 45° to the side of the
stove in order to direct the coal fed into the stove to the grate. Two supports
maintain the comb in position. The object of the elliptically shaped bars is to
conduct the fuel towards the movable grate. The bars of the elliptically shaped
set are arranged radially and are longer at the sides and against the door than at
the back.
The movable grate is composed of three parts viz of a ring, a movable part
and a rod.
The ring is not entirely in the same horizontal plane, one portion thereof being
lowered to allow the passage of the movable grate. The said ring has formed
integral with it a piece having six teeth of unequal lengths and a fork which
serves as a support for the said toothed piece.
The movable part of this grate is composed of a kind of comb having teeth
alternating with the teeth fixed to the ring, and having between them a uniform
space of say 15/m. The movable part is operated by the said rod. Four lugs on
the movable grate embrace the central bar of the ring and serve as guides for the
said movable piece in its movements.
The said rod traverses a movable piece or slide in order that during the operation
of the grate, when the rod is caused to move from right to left and from left to
right, the said piece constantly accompanies the rod and prevents the air from
entering the stove through the opening through which the rod moves.
The door through which the stove is fed is fixed by means of a gudgeon which
passes into an oval hole. This arrangement prevents the door from falling when.
it is opened. In fact, when the door is completely opened, the gudgeon bears, with
its rear part upon a bearing piece and cannot fall. For closing it again, it must be
lifted so as to displace the gudgeon in its oval hole.
The feed tube is cut out at the lower part, so that it shall not be seen through
the mica in the stove door. The said tube has at its rear side a series of holes
which provide a supplementary outlet for the gas generated.
The smoke tube or chimney is of sheet iron and terminates in the form of a
spur in order to facilitate the introduction of the pipe into the plate closing the
chimney.
When the stove is to replace a fire-place for apartments, this fire-place is closed
by means of a closing plate, and in order that this closing plate can be adapted to
any fire places which have about the same dimensions, it is made in three pieces.
viz a central plate, a side plate, and a regulator plate. These three plates slide
one upon the other, and can be fixed in any positions by a knob.
The upper part of the central plate bears upon the iron of the fire place behind.
The vertical sides of the side plates are at right angles and the bent portions of
these sides engage with grooves or tongues.
At the height of the smoke conduit or tube of the stove, the central plate has an
elliptical opening in which the pipe of the stove enters. A. hole of from 12 to
15 centimeters in diameter in this plate, leaves a passage for the vitiated air.
Behind this opening is the regulator.
This regulator is composed of a very light metal plate suspended by its upper
edge upon two pivots and carrying a small counter weight at its upper part. The
closing plate is placed a little behind the fire-place, and as it is usual to provide for
the admission of air from outside, the air becomes heated in contact with the
smoke pipe and escapes into the apartment in which the stove is placed.

page_text: An Improved Stove or Fire-place.
I, MARIE EDMOND PHILBERT Chaboche, of Paris, France, Engineer do bereby
declare the nature of my 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 an improved stove or fire-place. The said stove
possesses numerous advantages amongst which are the following viz :-Its
arrangement is such that the fire is visible; its management is easy; it is very
stable; the regulation of the heat is easily effected; it is very durable; and its
shape and size enable it to be easily adapted to ordinary fire-places.
The improved stove is mounted upon a platform having wheels or rollers, so that
it can be moved from place to place, and is adapted to be supplied with fuel from
the top of the outer casing.
The furnace of the stove is provided with a refractory lining and has at the
bottom an elliptical ring and a movable grate. A comb is arranged above the
furnace-door to direct the fuel on to the grate. The said door has sheets of mica
inserted therein to permit the fire to be seen.
The construction and operation of the improved stove will be readily understood
from the following description reference being had to the accompanying drawing.
In the said drawing
Figure 1 is a vertical section showing the general arrangement of the stove.
Figure 2 is a view of the comb.
Figures 3 and 4 are perspective views of the supports for the said comb.
Figure 5 represents a supporting rod at the rear of the movable grate.
Figures 6 and 7 are details of the hook for shaking the movable grate.
Figures 8, 9 and 10 represent respectively a plan, end view, and underside view
of the support for the refractory lining and the elliptical ring.
Figure 11 is a rear view of the said elliptical ring, and
Figure 12 is a plan of the same, showing the movable grate in position.
Figures 13, 14 and 15 are views of the movable grate.
Figure 16 shows details of the hinge of the furnace-door.
Figure 17 shows details of the closing device of the said door.
A is the platform which carries the stove proper. The front portion of this
platform serves as a cinder-guard or fender.
The connection between the stove
and the platform is effected by means of a flange to which the casing of the stove
is bolted, and by means of a groove and tongues. The platform is supported upon
two large rollers at the side and a small one placed in front. These rollers are
placed in bronze bearings and that in front is provided with a brake having a
screw X placed above and which is tightened or loosened at will. B is the ash-
box which is arranged in such a manner as to prevent the air passing through the
joints around the same. For this purpose the ash-box is suspended and its side
edges slide in two grooves. The edge of the front side of the ash-box is inclined,
and, in order that this edge shall constantly bear against the front of the stove,

page_text: two wedge-shaped lugs d on the ash-box are adapted to impinge against two other
wedge-shaped lugs e on the stove, whereby the ash-box by its weight maintains a
tight joint. For opening the ash-box it is sufficient to slightly lift the handle
thereof and to draw the box outwards. The admission of air through the ash-box
is controlled by means of an ordinary diaphragm provided with a button.
The rear side of the ash-box is movable in such a manner that the ash-box can
serve as a scoop for.withdrawing the cinders.
C is the door of the stove which is provided with holes in which are placed
pieces of mica permitting. the fire to be seen.
The binge on which the door moves is shown in Figure 16. This hinge is not
integral with the front of the stove, but has a rectangular rib terminating in a
T-shaped extension v at its upper part, and in a lug x at its lower part. This
part of the hinge engages with a corresponding aperture in the casing of the stove.
When the hinge is inserted in the said aperture, it is only necessary to allow it
to descend in order to be firmly engaged.
The closing or locking devices of the door are represented in Figure 17. They
I have the appearance of another hinge and are provided with an appendage for
permitting the door to be lifted with a poker when it is desired to open the said
door. The lower part of the locking device is connected to the front of the stove
casing in the same manner as the hinge. The upper extremity of the lower portion
of the said locking device has two converging inclined planes and the lower edge
of the upper portion is hollowed out for receiving the angular edge of the lower
portion.
The teeth of the comb D are inclined at an angle of 45° to the side of the stove
in order to support the fuel proceeding from the feed chamber J and direct it
afterwards to the grate.
The said comb is carried upon two pieces t, t¹ (Figures 3 and 4), which have
incisions into which enter lugs cast integral with the said comb. Ribs provided
upon the pieces t and t¹ fit the sides of the stove so as to obtain a rigid and solid
connection.
The object of the elliptical ring E is to direct the fuel towards the centre of the
grate F. This ring is supported by the plate M (Figures 8, 9 and 10) by means
of the projections S, S¹, S. The plate M also supports the refractory lining N,
which may be composed of fire-bricks. The part upon which the weight of the
bricks bears is strengthened by a rib M¹.
This arrangement has the advantage of enabling the elliptical grate or basket to
be removed without deranging the bricks. To hold the said elliptical ring in
position, cavities o, o are formed therein which cavities correspond with other
cavities o¹; o¹ in the plate M, so that when the corresponding cavities are opposite
each other pins can be inserted therein. To disengage the elliptical ring, the two
pins are withdrawn, the said ring can then be drawn forward so that the three
projections S, S¹, S¹¹ can pass through three corresponding cavities S, S¹, S¹¹ in the
plate M..
This elliptical ring E is solid in front and perforated at the sides and behind,
and is without any projecting portion either above or below. Its form is such as
to direct the fuel upon the movable grate F.
This arrangement has another advantage viz:-that of permitting the bricks to
be renewed without dismounting any part but the elliptic ring. The upper
edge E¹ (Figure 1) of the said ring forms a stop or ledge before the bricks.
The grate, Figures 13 and 14, is composed of three parts, viz: the ring h, the
movable part i and the rod T.
The ring is not entirely in the same horizontal plane, one portion thereof
being lower than the other to allow the passage of the movable grate i. The said
ring has formed integral with it a piece r having six teeth of unequal lengths and
a bar w which serves as a support for the piece r..
The movable part i is composed of a kind of comb having teeth alternating with
the teeth fixed to the piece r and having between them a uniform space of say

page_text: 15 millimeters. This movable part is operated by the rod T. Four lugs, not
shown, on the under side of the movable grate embrace the central bar w of the
ring and serve as guides for the piece in its movements from the front
rearwardly.
The rod T traverses a movable piece or. slide m, in order that, during the
operation of the grate, when the rod T is caused to move from right to left and
from left to right, the latter constantly accompanies the rod and prevents the air
from entering the stove through the opening through which the rod T moves:
The rod T of the movable grate Figures 1 to 5, is operated by a movable hook P,
Figures 6 and 7 provided at the centre with a bent finger P¹ which enters the
hole T in the said rod.
By lowering the hook, when engaged in the hole T¹ the tongues f and f¹ of the
rod P clasp the rod T, so that the said rod P forms practically one piece with the
rod T.
The arm of the lever is thus prolonged by the length of the rod P, which
prolongation facilitates the operation and prevents the person handling the same
from being burned.
The projection g upon the side of the tongue fl serves to lift and open the
furnace door and the feed door.
The feeding arrangements comprise the bearing piece G, the door H, the pivot I
and the feed-tube J. The door is carried by means the pivots I which are located
in oval holes in the casing. This arrangement prevents the door from falling when
it is opened. In fact, when the door is completely opened, the pivot which
occupied the position indicated in Figure 1, now occupies the position indicated in
dotted lines in the same Figure. For closing it again, it must be lifted so as to
displace the pivots in their bearing hole and brought back to the position indicated
in the Figure.
The feed tube J is cut out at the lower part, so that it shall not be seen through
the mica panes a in the stove door. At the rear it has a series of holes which
provide a supplementary outlet for the gases.
The smoke tube or chimney is of sheet iron and terminates in the form of a
spur, in order to facilitate the introduction of the pipe into the plate closing the
chimney (see Figure 1).
When the stove is to replace a fire-place for apartments, the fire-place opening
is closed by means of a closing plate, and in order that this closing plate can be
adapted to any fire-places which have about the same dimensions, it is composed
of a central plate p provided on each side with a supplementary plate q and the
regulator 8. These plates p, q slide one upon the other, and can be fixed in any
position.
The upper part of the closing plate bears upon the fire-place behind (see.
Figure 1). The vertical edges of the plates q are bent at right angles to four
grooves in which the blower of the fire-place also slides.
At the height of the smoke conduit tube of the stove, the central plate p has an
elliptical opening in which the pipe of the stove enters. A hole of from 15 to
16 centimeters in diameter in the plate p leaves a passage for the vitiated air.
Behind this opening is the regulator 8.
This regulator is composed of a very light metal plate suspended at its upper
edge upon two pivots, and carries a small counterweight at its upper part. The
closing plate is placed a little behind the fire-place, as it is usual to provide for the
admission of air from outside between the stove and the said closing plate. The
air passes in the direction indicated by the arrow 1 and becomes heated in contact
with the stove and the smoke pipe. It finally escapes into the apartment in
which the stove is placed in the direction of the arrow 2.
.
In order to increase the applications of the stove I sometimes provide a plate-
warmer Q, formed of a metallic plate pierced with holes and carried by three feet
having a special bend so as to fit the handle of the feed door,

page_text: I can also arrange a metal grate or kettle warmer R to rest upon the lower.
cinder plate by two feet, the said grate being hooked into the hole T¹ of the rod T
of the movable grate F. This grate R has the form of the front of the stove in
order to fit the same.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:
First Providing for hermetic closing of the ash-box B by making the front
plate of the said ash-box with sloping edges, by supporting the said front plate by
means of lugs d, e, and by causing the ash-box, the edges of which are bent, to
slide in two grooves which prevent the said ash-box from assuming an inclined
position.
Second-The ash-box, the rear side of which is movable upon a horizontal
axis g, thereby permitting it to be used as a scoop.
Third-The combination of the comb D, fixed firmly to the interior sides of the
fire-place by special hooks tt, a fixed elliptic ring E, a support for the fire-brick
and a movable grate F.
Fourth-The grate F composed of a ring made integral with a comb r,
between the teeth of which enter the teeth of a movable part i.
Fifth: The slide m through which the rod T of the movable grate passes for
the purpose specified.
