IMPROVEMENTS IN FIRE-GRATES AND STOVES
Year: 1873

page_text: LETTERS PATENT to John Barling, of Belle Grange, on Windermere,
in the County of Lancaster, for the Invention of " IMPROVEMENTS
IN FIRE-GRATES AND STOVES."
Scaled the 8th August 1873, and dated the 17th March 1873.
PROVISIONAL SPECIFICATION left by the said John Barling at the
Office of the Commissioners of Patents, with his Petition, on the
17th March 1873.
I, JOHN BARLING, of Belle Grange, on Windermere, in the County
of Lancaster, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN FIRE-GRATES AND STOVES," to be as follows:-
The object of my Invention is to economise fuel and diminish smoke
by producing a more perfect combustion of the fuel, and I accomplish
this upon the well-known principle of feeding each fresh supply of fuel
under the burning or incandescent fuel in the grate or stove.
The arrangements hitherto invented for carrying out this principle
have been too complicated and imperfect, which has prevented them
from coming into use.

page_text: My Invention consists in a very simple arrangement of fire-grate or
stove by which each fresh supply of fuel can be readily placed under
the burning fuel in the grate or stove. The bars forming the front of
open fire grates are made vertical instead of horizontal, or they may be
partly horizontal and partly vertical. The vertical bars are connected
together by a cross bar at their upper ends to form a kind of grid, and
each bar of the grid passes through a horizontal fulcrum bar which is
made capable of revolution or partial revolution, and the two ends of
which are carried in suitable bearings on the sides of the grate or stove.
Through this fulcrum bar the grid bars are made to slide. When fresh
fuel is to be supplied to the fire the grid bars by means of a handle or
key fitted to them are turned so as to raise the burning fuel, and then
the fresh fuel is inserted into the space left vacant. When this has
been done the grid bars are drawn outward, and being turned again into
the vertical position are thrust down into their place. A perforated
plate may be substituted for the grid bars, and for stoves or closed fire-
places either grid bars or a perforated or unperforated plate may be
used and arranged on any convenient side of the stove.
In some cases a plate is arranged in the bottom of the fire-grate to
draw out like a damper to facilitate the placing of the fuel and the
burning of slack; also a horizontal bar or bars are placed behind the
grid bars, to which may be added a wire guard or screen to prevent
the burning fuel from falling out during the time the fresh fuel is being
supplied.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Barling in the Great Seal Patent Office
on the 1st September 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BARLING, of Belle Grange, on Windermere, in the County of Lancaster,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of March, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said John Barling, Her special license that I,

bars by means of a handle or key fitted to them are turned so as to raise
space
the burning fuel, and then the fresh fuel is inserted into the
vacant. When this has been done the grid bars are drawn outward, and
being turned again into the vertical position are thrust down into their
place. A perforated plate may be substituted for the grid bars; and
for stoves or closed firc-places either grid bars or a perforated or
unperforated plate may be used and arranged on any convenient side of
the stove.
In some cases a plate is arranged in the bottom of the fire-grate to
draw out horizontally like a damper to facilitate the placing of the fuel
and the burning of slack; a horizontal bar or bars may be also placed
behind the grid bars, to which may be added a wire guard or screen to
prevent the burning fuel from falling out during the time that fresh
fuel is being supplied.
Fig. 1 is a front elevation, Fig. 2 a sectional elevation, and Fig. 3 is a
plan section, illustrating a fire-grate arranged according to my Inven-
tion, and Figs. 4 and 5 are views corresponding respectively to Figs. 1
and 3, of another modification. Figs. 6 and 8 are detached views of
the fulcrum bar shewn in Figs. 1, 2, and 3, and in Figs. 4 and 5 respec-
tively, and Figs. 7 and 9 are detached views of alternative fulcrum bars.
Fig. 10 is a side sectional view, and Fig. 11 an end view of the lever
or handle for working the grid.
The
a is the front of a stove grate; b, the back of the fire-place of fire-brick
material, and c, sides of the fire-placc of the same material; d, the
bottom grate of the fire-place. The front fire-bar frame e has bearings
formed for the pivots f¹ of the fulcrum bar f, and these pivots (ƒ¹) may
be kept in their places by pins f2, as shown; g is the grid, the bars or
prongs of which can slide through the holes in the fulcrum bar (ƒ); e
are stops for preventing the grid (g) from turning too far.
modification shewn by Figs. 4 and 5 is the same as that shown by
Figs. 1, 2, and 3, except that the pivots of the fulcrum bar ƒ are
brought more forward, which will cause the grid (9), and bar (f) to
lift higher and give more space for inserting the fuel. The grid (9)
and fulcrum bars (f) are shewn in Figs. 1, 2, 3, 4, and 5, in their
normal position in full line, and in their position when fuel is being
supplied in dotted line. All the prongs of the grid need not go through
the fulcrum bar, and the fulcrum bar itself may be replaced by two

page_text: pivots, without connecting bar between them; but the connecting bar
makes the pivots more steady and less accurate fitting will suffice.
The handle shewn by Figs. 10 and 11 fits upon the projection g¹ from
the grid, being secured thereto by giving it a partial turn like a
bayonet fixing. It is best to wait until the fuel to be lifted has
burned to coke or cinder before raising it by the grid to supply fresh
fuel.
I have now particularly described the nature of my Invention, and
the mode of carrying it into effect, and claim as my Invention the
system or mode of constructing fire-grates or stoves, so that the fuel
or partly burned fuel in the grate or stove can be lifted by a grid plate
or its equivalent, to supply fresh fuel worked substantially as herein-
before described and illustrated by the accompanying Drawings.
In witness whereof, I, the said John Barling, have hereunto set
my hand and seal, this Twenty-eighth day of August, in the
year of our Lord One thousand eight hundred and seventy-three.
