PROVISIONAL SPECIFICATION.
Improvements in Domestic or like Stoves or Fire Places.
I JOHN WATSON SPENCER, of Newburn, Newcastle on Tyne, in the County
of Northumberland, Steel Manufacturer do hereby declare the nature of this
invention to be as follows:-
This invention relates to certain improvements in the construction of domestic, or
like stoves or fire places designed to improve the combustion of the fuel or products
of combustion therefrom.
In carrying out my present invention I employ a grate, or fire basket of
substantially ordinary or convenient form; with more, or less vertical, or sloping
fire resistent back, and with or without passages or conducting means for extra
amount of air to back of the mass of fuel when in a deep body if desired and usual
coved, or sloped rearward wall, or surface, above the fire basket, which may be
made of reflecting material, if desired, and in some cases be pierced with an opening
to the flue closable by a register door, so that if required on first lighting the fire
the current may pass upwards therethrough, and then when the draught in the flue
is once established it may be closed.
The bottom of the fire basket is more or less open to a passage which from the front
of the grate beneath the fire basket passes to the back thereof and then up behind it
to the chimney. The front opening of this passage is closed by a plate which
conveniently may form the front of a tray which can serve as a receptacle for ash
and by the drawing forward, more or less, of this plate access of air to the passage
below the fire may be controlled or regulate the draught. Rearward of the fire
place commanding the flue is located a damper or valve-in new grates made
according to my invention-controlled by a rod passing to the front of the stove in
any convenient position. In old stoves adapted to my invention a damper or valve
back of the fire place may be fitted and operated by a handle rod supported under-
neath the grate and coming to the front thereof.
By these means air to support combustion is controlled to pass into and amongst
the fuel in the fire grate and thence with the products of combustion is caused to
pass in a downward direction into the passage below and therealong into the flue,
the flow being regulated by the damper or valve in the flue coöperating with the
front plate, or valve, and as a result more complete combustion and economy is
attained by simple and inexpensive means.

Improvements in Domestic or like Stoves or Fire Places.
I, JOHN WATSON SPENCER of Newburn, Newcastle on Tyne, in the County of
Northumberland, Steel Manufacturer 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 improvements in the construction of domestic or
like stoves or fire places designed to improve the combination of the fuel or
products of combustion therefrom and is designed to simplify the construction

page_text: shewn and described in the Complete Specification of Patent No. 22541 granted to
me and dated 8th December 1892.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 shews by a front view one form of my improved fire place by way of
example.
Fig. 2 shews a vertical sectional view of the same and
Fig. 3 shews a horizontal sectional view, the section being taken a little above
the bottom of fire basket on the line 1-1 of Fig. 2.
In carrying out my present invention 1 employ a grate, or fire basket a of
substantially ordinary or convenient form; with more, or less vertical, or sloping
fire resistent back b, and with or without passages or conducting means for extra
amount of air to back of the mass of fuel when in a deep body if desired and usual
coved, or sloped rearward wall, or surface c, above the fire basket which may be
made of reflecting material, if desired, and in some cases be pierced with an
opening d to the flue e closable by a register door d¹ so that if required on first
lighting the fire the current may pass upwards therethrough, and then when the
draught in the flue is once established it may be closed.
The bottom of the fire basket is more or less open to a passage f which from the
front of the grate beneath the fire basket passes to the back thereof and then up
behind it to the chimney.
The front opening of this passage is closed by a plate which conveniently may
form the front of a tray g which can serve as a receptacle for ash and by the
drawing forward, more or less, of this plate access of air to the passage f below the
fire may be controlled or regulate the draught.
Rearward of the fire place commanding the flue is located a damper or valve h-
in new grates made according to my invention-controlled by a rod h¹ passing to
the front of the stove in any convenient position.
,
In old stoves adapted to my invention a damper or valve i back of the fire place
may be fitted and operated by a handle rod i supported underneath the grate and
coming to the front thereof. By these means air to support combustion is controlled
to pass into and amongst the fuel in the fire grate and thence with the products of
combustion is caused to pass in a downward direction into the passage below and
therealong into the flue, the flow being regulated by the damper or valve in the
flue cooperating with the front plate, or valve, and as a result more complete
combustion and economy is attained by simple and inexpensive means.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The construction and use of a domestic or like fire place or stove having a
fire basket or fuel container, the bottom of which is open, more or less, to a passage
which from the front of the grate passes beneath the fire container to the back and
to the flue, the passage of air and products of combustion through said passage.
being controlled or regulated by means of a slideable ash tray having a front plate
and by a draw valve or damper in said passage at rear of ash tray, or alternatively
in the flue itself in rear of the stove as and for the purpose set forth.
2. The construction of stove or fire place with bottom passage leading to the
flue in combination with means for controlling or regulating the currents of air and
products of combustion as set forth and shewn by the drawings.
