WORDELE DELICATION
Heaters for Fire-places.
A communication from ALBERT EDWARD LYTLE, Manufacturer, of 1339, Montana
Street, and SIMEON DANIEL OVITT, Manufacturer, of 6658, Michigan
Avenue, both in the City of Chicago, County of Cook, and State of Illinois,
United States of America.
I, Alfred Julius Boult of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, 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 certain new and useful improvements in fire-places and
stoves, and consists in certain peculiarities of the construction and novel arrangement
and operation, of the various parts thereof, as will be hereinafter more fully set
forth and specifically claimed.
The objects of this invention are, first to afford an attachment for fire-places,
which shall economize in the amount of fuel consumed, yet will produce from a
given amount of fuel, an increased quantity of heat; second, to supply the rooms
thus heated with fresh, pure air, rendered more wholesome and healthful by the
addition of moisture, or a limited amount of steam, and furnish a number of rooms
with heat, from the same grate or firo.
In order to enable others skilled in the art, to which the invention pertains to
make and use the same, I will now proceed to describe it, referring to the
accompanying drawings, in which-
Figure 1, is a front view in elevation of the grate or fire-placo, with the heater
in position, showing the mantel and a section of the wall of the room with the
register open.
Figure 2, is a vertical view, taken on line 2, 2, of Figure 1.
Figure 3, is a cross or plan sectional view, takon on line 3, 3, of Figure 1, with
the grate and doors removed. And
Figure 4, is a perspective view of the bottom, back, and one of the side walls of
the heater detached.
Similar letters refer to like parts throughout the different views of the drawings.
A, represents the exterior wall of a house or building, and B, represents the
interior wall thercof. C, is a mantel or ornamental front piece, within which is
placed and connected at its lower portion, to the heating apparatus, the hot air pipe
or flue F, which may extend upwards, within the smoke flue, to any desired point,
and may have openings F, into the interior of the room where the grate is placed,
or into the rooms above.
Where the heater is designed to furnish warmth for one room only, the hot air
flun F, may be constructed so as to open into the room at a proper point above the
top of the mantel as shown, or otherwise if desired, but where there are several
rooms to be heated, from and by the same grate or fire, the hot air flue F, is
extended and may have suitable pipes or connections (not shown), connected
therewith, and opening into the rooms, and provided with registers, or cut-offs a, to
oloso said openings, when it is desired to prevent the room or rooms becoming too
warm.
Gr, is a corrugated back, which is preferably made of cast or sheet iron, and of
the form shown in Figure 4, having its lower end open, and its upper front portion
formed with an enlargement or forward curve g, the top of which is bent backward,
and forms the hot air chamber gl, into the upper surface of which is provided tho
opening g', to which is connected the hot air pipe or flue F.

page_text: In each side of the corrugated back G, and preferably in the upper and enlarged
portion thereof, is formed an opening of any desired size and form, which receives
the heated air from the jamb or side walls G', which like the rear or back wall G,
are constructed with vertical corrugations, but without the oxtended portion g, each
of which side walls is provided at a point to correspond with the openings g (only one
of which is shown in Fig. 4) in the sides of the corrugated back G, with openings
(not shown), to admit the heated air from their chambers to those of the back.
The jambs or walls G', may be made of any suitable material, but preferably of
sheet or cast iron, and have their lower portions open to receive air, as will be
presently explained.
On the bottom of the open space or fire-place D, is placed a hollow base H, of
proper size and form, and of any suitable material, to receive and admit therefrom
the cold air.
The upper surface of this base, is provided with openings h, at suitable pointe,
to connect with the bottom of the jamb or side walls G', and the bottom of the
back G, which are placed and secured over said openings.
As will be seen in the drawing, the upper surface of the base H, is about flush
with the hearth H¹, which is commonly placed lovel or flush with the floor of the
room.
The front of the base H, is provided with one or more openings h', which
connect with a pipe, and open in the surface of the hearth H', as shown in
Figure 2, in front of the grate.
The rear side of the base H, is provided with one or more openings A, which
have connected thereto, a pipe or pipes h', which extend through the outer wall A,
of the building, and receive fresh and pure air therethrough.
In the upper surface of the bare H, at any suitable point, is provided an
opening, having a cover, beneath which is placed a water receptacle or
vessel I, which may rest on the bottom of the hollow base H, and have its upper
portion or rim, a slight distance from the lower surface of the top of the base H,
or may be secured to the underside of the upper surface of the base, and provided
with openings, through which the steam or moisture from the water may escape
into the air chamber, formed by the hollow base, and be carried from thence
through the corrugations of the side or jamb walls G', and back G, into the hot
air fluo.
Near the front of the back G, and beneath the grate K, is formed in the
baso H, an opening m, having a cover m', through which the ashes falling from
the grate, may be dumped into a suitable chute m, leading to the basement or
below.
On the upper portion of the enlarged part g, of the back G, is placed preferably
in an angular position, and extending from one of the walls G', to the other, a
plate L, having slots i, and provided with a movable door L', to close said slots
when desired, and to regulate the draught of the fire.
As shown in Figures 1, 3, and 4, the front of the side walls, are provided with
eyes n, for the reception and retention of suitable hooks or pintles n', secured' to
the doors N, which may be provided with panels of glass, or other suitable
transparent material, and are designed to be closed in front of the grate, and thus
prevent the escape of dust, soot or smoke, and present a more attractive appearance,
especially when a fire is not required.
By using the hollow base H, it is evident that the air admitted thereto, through
the passages A, and ', will be pure and free from dust or ashes, and will absorb
moisture from the water in the vessel I, or be impregnated with steam therefrom,
when the same is heated to a sufficient degree to produce steam, and that the thus
moistened air, will asceud through the corrugations of the back G, and, side
walls G, and be heated therein, and pass therefrom through the hot air flue, and
its openings, into the rooms to be heated.
.I
In the drawing it will be seen, that the inner surfaces, of the side walls G', are,
provided near their lower portions with a horizontal ledge or brackat. O. unon

page_text: which will rest the sides of the grate K; this construction renders it an easy
matter to insert or withdraw the grate, and affords a strong support therefor.
