WILLIAM ROBERT Lake, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, "IMPROVEMENTS IN AND RELATING TO STOVES
OR FIRE-PLACES FOR DOMESTIC AND SIMILAR PURPOSES." [A communication from
abroad by Allan T. Bennett, of Kenosha, Wisconsin, United States of America.]
This Invention relates to improvements in and connected with stoves or fire-
places for domestic and similar purposes, and comprises the means, substantially as
hereinafter described, which I employ for the purposes of increasing the radiating
surface and improving the ventilation of the class of heaters hereinafter referred to.
In carrying the said Invention into practise I provide a fuel-receiving recess in
which the grate is arranged. The front of this recess is open, and the grate is
exposed in the usual manner; the lower part of the said recess forms the ash-pit.
The pit may contain a removeable pan as usual to collect the ashes and unconsumed
fuel. I construct and arrange the smoke flue in such a manner that it enters the
top of the recess at the front part thereof and curves upward and then downward,
and then leads upwards into the chimney flue. I provide a removeable hearth
standing on legs between which are spaces. There is an air-chamber which
extends underneath the ash-pit around the sides and back of the recess and around
the flue, and has an opening in front and underneath the ash-pit, also front openings
above the recess, but is elsewhere closed or tight; it may however have other front
openings, the object of its openings being to permit the lower or cold strata of air
to enter the said air chamber, become heated, and then escape in such manner that
the room in which the grate is situated will thus have its air heated and kept in

page_text: circulation, and also have the advantage of the heat radiated directly from the
incandescent fuel and from the exposed surface of the walls of the recess.
The outer wall, or the wall enclosing the air chamber, may be made of iron, so as
to adapt the parts to be set into the chimney-flue or fire-place of chimneys already
erected.
A stove or fire-place, constructed substantially as described, will take up the
lower or cooler air from a room in which it may be situated, and heat and discharge
into the same room the air drawn therefrom without in any way diminishing the
heating or warming capacity either of the fuel or of the parts of the structure, and
the air in the room will be kept constantly in circulation and pass out through the
flue in quantity sufficient to produce a proper ventilation.
The said stove is simple in its construction and cheap and durable, it being
understood that fire-brick may be employed in the usual manner, if deemed
necessary. In other words, a grate and fuel-chamber with an ash-pit and smoke-
flue is set into a chamber which passes underneath the ash-pit and back of and over
the fuel-chamber, and this surrounding chamber has front openings only for
receiving and discharging the air heated in the said chamber.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN AND RELATING TO STOVES
OR FIRE-PLACES FOR DOMESTIC AND SIMILAR PURPOSES." A communication fron
abroad by Allan T. Bennett, of Kenosha, Wisconsin, United States of America.
This Invention relates to stoves or fire places for domestic and similar purposes,
and comprises the means, substantially as hereinafter described, which I employ for
the purpose of increasing the radiating surface and improving the ventilation of the
class of heaters hereinafter specified.
The said Invention is illustrated in the accompanying Drawing, in which→
Figure 1 is a front view of a fire-place.
Figure 2 is a section on the line x, x, and
Figure 3 is a section on tho line y, y.
Like letters indicate the same parts throughout the Drawing.
A is a grate, and B is a fuel-receiving recess in which the grate is arranged;
the front of this recess is open and the grate is exposed in the usual manner, as
shown. C is the ash-pit at the lower part of the recess B; the pit C may contain
a removable pan, as usual, to collect the ashes and unconsumed fuel. D is the smoke-
flue; this flue D enters the top of the recess B and also the chimney flue, as shown.
E is a removable hearth standing on legs a, a, between which are the spaces a¹, a'.
F is an air chamber; this chamber extends underneath the ash-pit, around the sides
and back of the recess B, and around the fluo D. It has an opening b in front and
underneath the ash-pit, and front openings b¹, 6, above the recess B, but is else-
where shewn closed; it may however have other front openings, the object of its
openings being to perinit the lower or cold strata of air to enter the chamber F,
become heated, and then escape in such manner that the room in which the grate
is situated will thus have its air heated and kept in circulation, and also have the
advantage of the heat radiated directly from the incandescent fuel and from the
exposed surface of the walls of the recess B. The arrows in Figure 2 indicate
the direction of the draught through and over the grate and through the flue D,
and also of the air drawn into and discharged from the chamber F.
The outer wall, or the wall inclosing the chamber F, may be made of iron, so as
to adapt the parts to be set into the chimney-flue or fire-place of chimneys already
erected.
It will be apparent from the foregoing description, and by reference to the
Drawing, that a grate constructed substantially as described will take up the lower
or cooler air from a room in which it may be situated, and heat and discharge into
the same room the air drawn therefrom without in any way diminishing the heating
or warming capacity either of the fuel or of the parts of the structure, and the air
in the room will be kept constantly in circulation and pass out through the flue D
in quantities sufficient to ensure a proper ventilation.
The said stove is simple in its construction, cheap, and durable. It will be under-
stood that fire-brick may be employed in its construction in the usual manner, if
deemed necessary; in other words, a grate and fuel chamber with an ash-pit and
smoke-flue may be set into a chamber which passes underneath the ash-pit and
behind and over the fuel-chamber, and this surrounding chamber has front openings
only for receiving and discharging the air heated in the said chamber.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim,-
A fire-place or heater consisting of the grate, the recess B, the ash-pit, the flue D,

page_text: and the chamber F, with the openings or ports 6 and 6', or any of these parts con-
structed as shown, or such modifications thereof as will effect the purpose of this
Invention, combined and arranged with relation to each other substantially as and
for the purposes set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Nineteenth day of October, in the year of our Lord One
thousand eight hundred and eighty.
