Improvements in Fire Stoves or Ranges.
I EDWIN RUTHVEN CAHOONE Manufacturer of 33 Thomas Street, in Newark
New Jersey, U.S.A. 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 :-
My invention relates to stoves and ranges especially adapted for burning soft or
bituminous coals and particularly to the class of stoves employed for cooking, the
object being to produce perfect, or substantially perfect combustion of fuels rich
in hydrocarbons and thus to eliminate smoke and soot, effect an economy in fuel
and adapt the stove for use in broiling and toasting.
The invention will be fully described hereinafter with reference to the accom-
panying drawings and its novel features carefully defined in the claims.

In a stove of this class the combustion chamber at the front of the stove is
partially divided by a transverse air-duct or partition, usually pendent from the
top-plate of the stove, the portion of the chamber in front of said duct forming the
fuel-magazine and that back of said duct forming a back flue up which the hot
gases flow to the horizontal gas-passage or flue between the top-plate of the stove
and the crown plate of the oven. The fuel rests on the normally imperforate
1

page_text: bottom of the combustion chamber, the draft being downward in the fuel-magazine
and across the lower part of the latter front to rear and under the duct. This
draft is the normal air-supply, but, where the duct is hollow there is a hot air-
supply through the same, which discharges the hot air in jets, partly in a downward
direction and partly in an oblique direction, at its lower part.
I will now describe the construction with more particularity, premising that in
respect of parts not described the stove may be constructed in any way desired, or
according to known models. For convenience I have used capital letters to
designate major parts, and features as a whole, and numerals to designate the
smaller parts and details.
A represents the fuel-magazine, B the pendent air-duct, C the flue at the back
of said duct, D the flue over the oven, E the oven, F the bed on which the fuel
rests, the ash-box, H the ash-pan in said box, and I the stove-top or top-plate,
in which are the usual pot-holes; J is the flue under the oven, K is the collar to
receive the stove-pipe, L is the charging door for supplying fuel to the magazine A,
M is the hinged stove-front, as a whole, N is the swinging, removable hearth-plate,
O is the concave back wall of the flue C, P is the water-back, which forms the
upper part of said back wall, which has an ogee form, and Q is a chamber under
the stove for kindling, etc. This latter is a common device and may be used or
omitted, at will.
I will now describe these and other parts in detail in order to develop the nove!
features of the construction.
The transverse air-duct or partition, B, will be, by preference, suspended from a
section,, of the stove-top 1. Figs. 6, 8 and 9 illustrate this construction, taken in
connection with the general views, Figs. 1 and 2. The duct is hollow, consisting
of a front section, 2, provided (Fig. 7) with apertures 3, and of an imperforate rear
section, 4. It is made thus in two sections, joined together at 5, in order to avoid
coring. Preferably the top of the duct B will be open, and in the section / to which
it is secured will be apertures, 6, seen in Fig. 5, to admit air to the duct. The duct
will, however, be open at its ends also, to admit air, said ends being covered,
preferably, by ornamental, apertured plates, 7, seen in Figs. 2 and 6.
This duct B is provided on its front with an outer wall or shield, 8, seen detached
in Fig. 8. This shield is vertically corrugated, having upright ribs, 8ª, the grooves
between which are preferably deepest at their upper ends, and it has at its lower
edge a recessed, apertured, strip or plate, 8. When placed on the front of the
duct B there is an air-space 8* between said shield and the inner front wall of
the duct whereby the air entering this space from the duct is diffused and
heated before passing out through the perforations or apertures in the strip 8b to
the combustion chamber, and this air-space or jacket serves also to protect the
inner wall of the duct against the injurious influences of the intense heat. On the
shield 8, at one end, is a lug, 8, which takes under an overhang on the front wall
of the duct, and an apertured lug, 84, at the other end to receive a screw for
securing the shield to the inner front wall of the duct.
On the convex lower edge of the duct B, is secured a shield 9, which for
distinction I call a shoe. This shoe is preferably hollow, as seen in Figs. 1 and 9,
and has on it raised ridges or transverse hollow or solid ribs 9a; and it has also, by
preference, perforations between or through said ribs from which the hot air
entering the said hollow or air-space from the duct B, escapes in jets into the
combustion chamber. These ribs may extend up in front to the perforated
strip 8b.
Both the shield 8 and shoe 9 may be removed and replaced from the front of the
stove without the necessity of taking out the main body of the duct, the ends of
which rest in recesses formed in the side-plates of the stove-body.
The ends of the fuel-magazine A are lined with end-shields 10, one of which is
seen detached in Fig. 11. These two end-shields are alike except that they are
rights-and-lefts, and each has on it, by preference, ribs, 10ª, like or similar to the
ribs 8" on the shield 8; that is, the grooves between them are deepest at the upper

page_text: end, running out to nothing at their lower ends. These end-shields may be secured
by screws to the stove-walls and may also be removed and replaced from the front
of the stove.
The ends of the flue C are also lined with end-plates, 10%, one of which is seen
detached in Fig. 114. These end-plates are also rights-and-lefts; they need not be
ribbed, however. The parts of the end-plates, 10 and 10%, where they meet below
the duct B are, by preference, overlapped by rabbetting or gaining them and the
rear edges of the plates 10* are overlapped by the back wall O and water-back P.
If the plate 10 and the end of the duct B overlaps the plate 10 at its front edge,
and the wall O and water-back P overlap it at the rear edge, these will hold said
plate in position, but it may be secured to the side-plate of the stove at its top by a
single screw.
In the front of the stove, near the top, is the charging door L. This door is of
the usual construction except that it has in it register-apertures, and on its inner
face a register-slide, 11, provided with apertures and also with trunks, 11ª, forming
inwardly-projecting tubes about said apertures. These trunks serve in a good
degree to prevent the escape of smoke at the register-apertures but allow the air to
enter freely.
Below the charging door is situated the movable stove-front M. This front is
herein shown as hinged at the side to the stove and when thrown open exposes the
entire fuel-magazine down to the fire-bed. On the inner face of the front M, as
shown in Figs. 1 and 13, is a vertically ribbed and slotted plate, 12, seen best in
Figs. 1 and 4. The ribs on this plate or inner wall coincide with and form
continuations of the ribs on a fixed, convex, ribbed, lining plate, 13, situated in the
front of the stove below the charging door, as best seen in Figs. 1 and 2.
Mounted on the front M is what I call a window-plate, 14. This plate is so
mounted, as herein shown, that it may be lifted out and removed, or if preferred, it
may be simply let down, lugs on the lower edge of the plate engaging recesses in
the stove front M. Figs. 1 and 3 show the plate 14 in place. Fig. 4 shows the
stove as it appears when this plate is removed, and Fig. 44 shows the inner face of
the said plate 14. In this plate 14 are mica windows, 14ª, about which the air
passes inwardly through small perforations, such air entering caps or boxes, 14b, on
the inner face of the plate 14, over the windows. These caps have perforated
bottoms, as clearly shown in Fig. 44, and they serve to protect the mica windows
from smoke and yet permit air to enter about the windows and pass into the
combustion chamber.
It is not essential to my invention that the ribbed and slotted plate 12 shall be
mounted on and carried by the front M; it may be made separate therefrom and
be hinged to the stove as shown in Fig. 14, and the front M may be removably
connected to the stove in any of the ways known in the arts. 1 would say here
that as the fuel-usually soft coal in rather small pieces-deposited at the front
part of the magazine or combustion chamber is usually finer than that deposited
at the back, I prefer to construct the ribbed surface of the inner wall or plate 12:
as clearly shown in Fig. 14; that is, to construct in each of the grooves on its face
a rib which divides the groove longitudinally. The main ribs will usually be
hollow at the back, but the intermediate rib may be merely blade or web of
solid metal.
The hearth-plate, N, is pivoted to the hearth of the stove at one of its sides and
may be turned to one side by lifting it a little to clear it and then swinging it.
This plate is omitted from Fig. 13. In this plate is a register, 15, to admit air
under the fire-bed. This register will be closed when fuel rich in hydrocarbons is
being burned, as in that case no air should pass up through the fire-bed from the
ash-box.
The construction of the fire-bed, or fuel-supporting surface, F, will be best
understood by reference to Figs. 1, 2 and 10. On a permanent, or fixed plate, 16,
having in it slots extending from front to rear of the stove, forming a sort of grid,
is mounted a sliding grid, 17, which may be moved to and fro transversely of the

page_text: stove so as to put the slots in the two grids into register or out of register, at will.
As herein shown the sliding grid has a stem, 17ª, which projects through the side
of the stove and a forked handle or lever, 17b, which is made to engage a head or
shoulder on said stem, the handle or lever being fulcrumed below in a hole or holes,
or recesses, in the stove-plate. In burning soft or bituminous coal the grid 17 is
so set as to close the fire-bed against air arising from the ash-box into the
combustion chamber, but when ashes shall have accumulated in the latter, the said
grid may be removed to and fro a few times in order to allow the ashes at the
bottom of the fire to fall through into the ash-box. In order that this fire-bed
may clear itself the better, I prefer to flare the slots between the bars of the grids
in a downward direction, as clearly shown in Fig. 10, whereby the combined,
registering slots are widest at the bottom. This insures the free escape of any
'bits of coal or coke that can enter the slot in the sliding grid.
In rebuilding a fire, the removable front M is thrown open, after the hearth-
plate N is swung to one side, and the contents of the combustion chamber drawn
out into the ash-pan H. In this pan will be set, by preference, a screen, 18, outo
which the coke and ashes fall, the latter sifting through into the pan and the
former being shovelled back into the magazine or scuttle.
The draft being downward in the fuel-magazine A, the nature of the vertical
corrugations or air-flues in the shields or linings thereof permits the air to pass
downward about the fuel, the air-passages between the ribs being preferably
largest at their upper ends. This construction is very important for a store of
this class wherein soft, caking coal is to be burned.

be, by preference, of cast iron, but I do not limit

If otherwise, the coal would

myself in this respect; they
In order to form an obstruction to the coke from the coal working back under
the duct B, due to the pressure of the fuel above, the shoe 9 is provided with ribs
or downwardly projecting lugs, as shown, and the sliding grid, 17, has a shoulder 17
for the same purpose. This grid is also set, at the back, a little below the front
edge of the concave wall O, where a second step-like shoulder is formed for the
same purpose. The effect of this construction is to lower the fuel-supporting
surface, in the main, somewhat below the horizontal portion of the wall O, under
the duct B.
It will be noted by inspection of Figs. 1 and 7 that the upper part of the rear
section, 4, of the duet B, inclines toward the front of the stove. The object of
this is to afford room for the front pot-holes of the stove and to provide a wider
space for the reception of a toast-holder as will be described. In the side-wall of
'the stove is formed an aperture for the inspection of such a toast-holder and this
aperture is closed by a door, 19, which may be hinged at its lower edge and
adapted to be turned down in opening. This door is seen in Figs. 3, 4, 5 and 6,
where it is represented as at the right-hand side of the stove; but there may be
such a door at each side or either side of the stove, and in Fig. 1 I have shown
one at the left-hand side of the stove. This latter view best indicates the position
of the door with respect to the duct B and flue C. As the gases passing up
through this flue C, when the fire is well under way, will contain, practically, no
soot or free carbon, it will be obvious that the point selected is well adapted for
making toast, or the like.
Fig. 2 shows the arrangement of the damper, 20, for controlling the flow of
gases about the oven. This damper is arranged in the usual way, so far as its
effect in opening and closing the flue is concerned, but I provide means for
indicating to the user its position at all times; these I will now describe with
reference to Figs. 1, 2, and 2^.
The arbor or stem, 21, of the damper (Fig. 2) is pivoted at its inner end, has a
bearing at 22, on the crown of the oven and has an outer bearing, 23, in the sid
wall of the store. On the outer end of the stem 21 (Fig. 1) is a handle, 24, which
is adapted to indicate the position which the damper 20 occupies. For example

page_text: when this handle points toward the letter
on the side of the stove, as.
ور
in Fig. 1, it indicates that the damper is closed; if it points toward the letter "O,'
it indicates that the damper is full open, or turned back so as to lie flat on the oven,
and if it points toward the letter "D" (between the letters "C" and "O").
it indicates that the damper is only partly open. Heretofore such dampers have
been adapted to open and close fully, but not to stand partly open. In order to
cause the damper to stand partly open I employ the means indicated in Fig. 2^;.
that is to say, I form on the stem 21 a slight rib or enlargement, 25, which
is adapted to engage a corresponding-recess or enlargement in the bearing 23, in the
side-plate of the stove, when the damper is partly open. The spring of the stem 21.
will suffice to permit the latter to disengage itself and turn in the bearing 23, and
to cause the enlargements of the stem and bearing to engage with sufficient force.
to hold the damper in place.
The indicating letters "C," "O" and "D" may be formed on or in the metal by
casting, in a well-known way, so as.to be permanent.
It is very desirable that the lid-lifter, constantly in use with the stove, shall be
kept in a convenient place where it will be cool. To effect this I provide in the
outer, overhanging margin of the top-plate of the stove, an oblong aperture, 26,
(Fig. 5), to receive the end of the lifter 27. The part of the top-plate where this
aperture is formed is usually quite cool and the lifter, when supported in it, will not
get so hot that it can not be handled.
For Lurning hard coal, should the stove at any time be used for this purpose, the
sliding grid will be shifted so as to form an open grate below, and the register below
the movable stove-front M will be opened wholly or partially.
The object in providing the removable window-plate, 14, in the stove-front, is to
permit of mounting a broiler in the opening in the front, as seen in Fig. 6. This
broiler comprises a somewhat hopper-shaped casing, 28, provided with a cover, 29,
hinged to the lower, outer edge of the same. The smaller end of the casing
is adapted to fit snugly in the aperture in the hinged front M. The holder 30, for
the steak to be broiled may be of wire, in two parts, hinged together so as
to embrace the steak. It has a journal, 30%, at one end to fit in a hole in the end
of the casing 28, and another journal, 30, which engages an open slot-bearing, 31,
in the other end of the casing. This journal is prolonged to form the handle of the
holder, by which the latter may be rotated in its bearings. The cover 29 is closed
when the broiler is in use. The lower, horizontal side, or bottom, of the casing 28
is slightly depressed or concave, and it has a hole, 32, at its lowest point, through
which the juices and fat from the meat flow out and fall into a platter or
receptacle, 33, set on the hearth of the stove under the casing.
It is not essential to my invention that the broiler-casing 28 shall be detachable
from the stove-front. Indeed the said front being hinged or removable, said
casing 28 may be cast in one with it and have a detachable cover of tin-plate, sheet-
iron, or the like, and the window-plate 14, may be made to fit and close the front
of the broiler-casing when the broiler is not in use. This construction is illustrated
in Figs. 14 and 14A, wherein the casing 28 is shown as formed integrally with the
front M, and the window-plate 14 is represented in place thereon. I have not
shown the tin-plate or cover, used to close the casing 28 when broiling, as this inay
be of any kind. The casing 28 has the slot 31, and a wicket plate, 31ª, to close
the same.
I have shown the stove provided with a water-reservoir, R, at its back, and
this will be desirable where the water-back P can not be used; but neither
of these devices are essential to my present invention. The water-back might be
replaced by a tile.
Fig. 12 illustrates a construction of the hollow partition or duct B in which the
outer plate or shield 8 is made integral with the front section thereof, the air-
chamber or jacket between them being formed by a perforated or apertured
diaphragm, 8, in the duct, said diaphragm thus forming the inner front wall of the
duct. The objection to this construction lies in the necessity of discarding the

page_text: entire duct, or at least the front section thereof-when the front shall have
become too much injured by the heat to serve its proper purpose.
It may be explained that the object in recessing, or setting back the apertured
strip 8 of the duct or shield, is to prevent the perforations therein from becoming
clogged by the fuel, cinders and ashes.
In the top-plate of the stove, near the front, is provided a simple and convenient
wicket-device, illustrated in Fig. 15, one view in this figure showing the wicket-
slide 34 partly drawn out so as to uncover an opening 35, for the insertion of
a poker into the combustion chamber, and the other view showing the slide 34
detached. The opening 35 extends out to the edge of the top-plate of the Elove
and has rabbetted margins in which the slide 34 fits and rests so as to close
the opening and be flush with the stove-top. To retain the slide in place it is
provided with a T-piece, 36, on a downwardly curved neck. This 1-piece is passed
down through the opening and then turned crosswise so that its ends take under the
margins of the opening, as shown, whereby it serves to keep the slide down
in place.
I wish to be understood that I do not limit myself to the specific construction of
the stove and its parts as herein described as this may be varied to some extent
without materially departing from my invention; nor do I limit my invention to
cooking stoves and ranges as some of the features thereof may be employed in
heating stoves, fire-place heaters and the like with only such slight modifications as
would suggest themselves to any one skilled in the art to which the invention
pertains.
In producing the upright draft, grooves or flues at the side or sides of the fire-
box, which grooves are closed at their fronts to form flues by the fuel itself,
I prefer, as I have stated, to make them deepest at their upper ends, and when
constructed in this manner I prefer to give them the proper extra depth by
projecting the dividing ribs between the flues more at the top than at the bottom
so that the top of said ribs overhang. This serves to prevent the fine coal,
ashes, etc., from choking up the flues. These flues, however formed, serve a useful
purpose in providing an always open outlet for the gases rising from the hot,
caking fuel which prevents their escape upward and out into the room and compels
them to pass down along the wall of burning fuel where they are consumed. I do
not limit myself to forming these upright flues in exactly the manner herein shown,
they may be formed in any satisfactory way.
Having now described and ascertained the nature of my invention and in what
