Improvements in Stoves, Furnaces, and the like.
I ALEXANDER MELVILLE CLARK of the firm of A. M. & Wm. Clark of 53 Chancery
Lane, London, Fellow of the Institute of Patent Agents do hereby declare the
nature of this invention (a communication to me from abroad by Otto Paul Elterich
14 Library Court Newark New Jersey, Gotthold Otto Elterich, 14 Library Court,
Newark, New Jersey, George Meier, 137 William Street, New York and Charles
Emil Meier, 406 Pearl Street, New York, trading as The Elterich Art Tile Stove
Works of Newark in the County of Essex Stato of New Jersey United States of
America) 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 improvements in stoves, furnaces, and the like.
The invention will be described with reference to the accompanying drawings
is a vertical transverse section
forming part of this specification, wherein Figure
on the plane of the line c-c figure 2, of a stove constructed in accordance with this
invention. Figure 2 is a partly broken front elevation of the stove.
Figure 3
is an enlarged detail view of a portion of the wall of the stove. Figure 4 is a
vertical cross section on the line k-k figure 3. Figure 5 is a plan view of the fire
pot and its fork. Figure 6 is a top view of the grate and its cleaning rake. Figure 7
is a longitudinal section on the line cc figure 6. Figures 8 and 9 are detail
sectional views of modifications.
A in the drawings represents a casing or framework of a stove in which is hung a
grate B. The grate B is shown pivoted at or near its ends and adapted to turn on
said pivots so as to deposit the aslies, &c., from the same upon the receptacle 6 beneath
it. Dis a fire pot above the grate B, and it is shown provided with a series of slots
or apertures d. The lower end of the fire pot D comes near the grate B so that the

may be of any desired construction provided it has suitable openings d to permit the
passage of my improved fork E across the fire pot, as clearly indicated in Figures 1
and The fork E consists of a heade from which project a number of prongs f
(see figure 5). are sockets on the side of the head e opposite the prongs adapted
to receive lugs on the handle F whereby the fork may be manipulated. The handle F
may by this construction be removed from the fork when the fork is passed into the
fire pot D.
As shown in Figure 1, the casing A of the stove or furnace is provided with a
horizontal opening & formed by two shelves or supports ij into and through which
opening the fork E may be passed. The opening G is aligned with openings d in the
fire pot D, and the fork E rests upon the lower shelf as indicated.. The distance
between the shelves ij or, in other words, the height of the opening G is about the
same as, or slightly more than, the height of the head e of the fork E, so that said
head will have a free sliding movement within said opening, and so that the upper
side of the head will come against the shelf j, while the underside of the prongs f
and head e rest upon the shelf i, thereby preventing the outer ends of the prongs
being depressed by the weight of the coals in the fire pot. The head e closes the
opening G to prevent the passage of dust. The sockets y are so arranged on the
head e as to permit the lugs h to be withdrawn from the same by a downward and
outward movement when the fork is in the opening G, as indicated in figure 1.
the door of the furnace which may be of suitable construction and provided with an
opening m to permit a key or the like to be inserted to operate the grate B. The
door may also be provided with an opening n that may be covered by a hinged
latch or flap o, so that the fork E may be passed into the furnace and through said
opening without opening the door 1, and so that the handle F may be removed from
lis

page_text: the fork E and the 'opening n closed to prevent dust, &c., passing out through said
opening. The door I need not extend up as far as the opening G, in which case the
flap o will be attached directly to the casing A.
The improved fork is used as follows:-The fork E is passed into the furnace or
stove through the opening G so that its prongs will pass through the openings d in
the fire pot D, and also pass through the bed of coals or ashes in the fire pot, so as
to separate the contents of the fire pot into two parts. The handle F is next removed
and the flap o closed, whereupon the grate B is turned upon its pivots, or the rake H
manipulated to clear the grate from ashes, cylinders, clinkers, and the like, or the
grate otherwise removed from beneath the cinders and ashes, whereupon said cinders, &c.,
will be deposited upon the receptacle or elsewhere, while the fork E sustains the
coals and fire above the fork, an open space being left beneath the fork, as shown in
figure 1. The grate B is next turned to its proper position and the fork withdrawn
from the fire pot, whereupon the coals, fire, &c., will pass down upon the grate and
continue to burn with new vigor like a fresh fire free from cinders and ashes, while
the rake H hangs down, as in Figure 1, out of the way of the grate.
In order to clear the grate from any cinders or clinkers that may adhere to the
same, and also to rake the fire without turning the grate, I place beneath the grate a
Ι
rake H which consists of a rod or bar p that carries at one end a cross bar
from
which project a series of prongs that pass into the slots or openings & in the grate
(see figure 6). This rake H is supported by, and adapted to slide in, a bearing or
box t, which permits said rake in its normal position to hang down, as in Figure 1, so
that the ends of its prongs are passed but slightly into the slots s, and also permits
said rake to be lifted, so that its prongs may pass through the grate B, as indicated in
Figure 7. This up and down movement of the rake is permitted by the tapering
shape of the bearing (see Figure 1). The rake H is adapted to receive a key or
handle u (see dotted lines Figure 1) whereby said rake may be lifted and turned on
its longitudinal axis and drawn longitudinally. When the rake is lifted and turned
as stated, the grate B may be turned, as shown in Figure 2, to dump the ashes.
order that the grate and fork when turned to the position shown in figures 2 and 7
may lie close together, as in figure 7, the under side of the grate may he cut away
at which permits the rod p of rake to come close against the grate when the same
is turned, whereby the prongs may pass through the grate to the full extent in
whatever position the grate may be.
In
The object of this rake H is to clear the grate of clinkers, etc. This is done by
moving the rake back and forth so as to draw the prongs through the slots s in the
grate, while the doors of the stove are closed.

In order to increase the heating power of the stove and to assist the burning of the
material in the stove, one or more water reservoirs 1, are placed in the stove (as
shown in figure 1) at the sides of the fuel box J. a² is a tube or the like, through
which water may be admitted to the reservoirs I. The reservoirs I, connect by
tubes with a vertical tube that extends down to the fire-pot D (see figure 1).
At the fire-pot D the tubed branches into one or more tubes e², which extend around,
or partially around, the fire-pot D, which latter tubes are provided with holes on
the inner side. By this means the water coming from the holes in the tubes e is
immediately evaporated and produces an inteuse burning of the fuel, thereby
increasing the heating power of the stove. This evaporation of the water also assists
the draught of the stove. The warın air passing through the stove takes up moisture
from the open end of the tube a² and is thus fairly saturated.
Another part of the invention relates to improvements in casings for stoves,
furnaces and the like, which is shown in figures 1, 2, 3, 4, 8 and 9. This casing
consists primarily of metallic uprights L, connected by cross bars (as in figure 3),
whereby an open frame-work is produced. M are a number of blocks or tiles, made
of clay, porcelain, or other suitable material, which tiles are provided on one side
with projections that are shown passing between the cross-bars of the frame-
work. The projections are shown in figure 4 to be wrapped with wires /² that are
lapped over the cross-bars f, whereby the tiles are held upon the frame-work. The

page_text: projections in figure 4 are shown tapering, while in figure 8 they are in the form
of beaded studs. When the tiles are in place in the frame-work a suitable lining N,
of cement or similar material, is placed over the cross-bars and on the inner side of
the tiles M, so as to cover their projections, whereby all the cracks between the tiles
are covered, and the whole mass forms a compact structure, the wires and projections g³
being embedded in the cement. By this means the tiles are securely held in position,
and a light, cheap and durable casing is produced. Of course the tiles M may be
decorated in any well known or desired manner. In the modification shown in
figure 9, the tiles M are shown having the wires connected directly to them
without the intervention of the projections g³.
Of course, the fork, or rake, or the different features of the invention, may be used
separately in different stoves, or all combined in one stove, as may be desired; it not
being necessary for this invention to place all the different parts hereinafter claimed
in one structure.
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-
1. The combination of a fire-pot, having openings on its side, with a fork adapted
to pass through said openings and through coals in the pot, and to support the fire,
coals, etc., in the pot, above the grate, substantially as described.
2. The combination of a stove casing having a fire-pot provided with side openings,
and a horizontal opening G, with a fork adapted to pass through said opening G and
to extend through the fire-pot to support the coals, etc., in the same above the grate,
substantially as described.
3. The fire fork E, consisting of the head e, having the prongs f, in combination
with the supports i,j, whereby said fork will be held horizontal, while permitted a
sliding movement, substantially as described.
4. The fire-fork E, consisting of the head e and prongs f, combined with the
handle F having lugs h, and with the sockets g, carried by the head e, to receive the
lugs, substantially as described.
5. The combination of the casing A, having door 1, opening n and flap o, with
the fire-pot D, having side openings d, horizontal supports i, j, and fork E, adapted
to pass across said fire-pot, all arranged substantially as herein shown and described.
6. The combination of the grate B, with the rake H, having the prongs that
always enter the slots in the grate and the bearing t for said rake, which permits the
rake to be raised and lowered and to be moved along and through the grate while the
doors of the stove are closed, substantially as described.
7. The fire-pot D, combined with the reservoir I, perforated tube e* and tubes
connecting the reservoir with said tube e³, whereby a jet is thrown in proximity to
the fire to increase the burning of the same, substantially as described.
8. The fire-pot D, combined with the reservoir I, perforated tube e³ and tubes
connecting the reservoir with said tube e and with the tube a² extending from the
reservoir and open on top, substantially as described.
9. The frame L, f, combined with the tiles M and the cement lining N, substan-
tially as described.
10. The frame I,, combined with the tiles MI, having projections g³, wires h³,
and cement lining N substantially as described.
