I, JOSIAH BARBER of Roscoo Place, Sheffield in the County of York Manager do
hereby declare the nature of my said invention to be as follows:-
My invention relates to improvements in the construction of Stove Grates, and
more particularly to the backs of such Grates or Fire places.
The object of the invention is to enable the heat of the fire to be radiated into the
room, and otherwise controlled, as desired and in a very simple manner.
In carrying out my invention in an ordinary stove grate for example, I construct a
metallic back plate or radiator somewhat similar to a fall door, having its axis placed
upon its lower edge, and its top edge is arranged to rest against the inside of the
stove front, or against the back, as the extreme limits of its movement, or to stop or
remain stationary at any intermediate point.
I prefer to make the axis or part on which the plato or radiator turns, a solid roller,
fitting into a semicircular groove placed horizontally above and upon the top edge of
the fire brick back, or thereabouts, so that when the radiator plate is upright the
chimney aperture is wide open, and when brought forward to the extent of its
movement, and resting with its edge against the front of the stove, the chimney is
closed.
The radiator plate is provided with a series of openings for the smoke and products
of combustion to pass through, and these may be closed by means of a sliding plate
at the back of the radiator.
I prefer to make the smoke openings in the radiator in the shape of long vertical
slots; for example I find that five of such slots of three quarters of an inch wide,
answer well in a stove of ordinary size, especially if the radiator is raised about an
inch from the front plate.
When the radiator is closed, the angle of its face should be about forty five degrees
or thereabouts, but I do not bind myself to any particular angle.
A set screw for adjusting the radiator for a short distance from the front plate of
stove may be fixed to the front plate if desired.
When fires are not required it is intended to shut down the radiator, and to close
he slots so as to prevent dirt or soot from the chimney entering the room, but if
entilation is desired the sliding plate is drawn on one side and the vertical slots
eft open.

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 :-
My invention relates to improvements in the construction of stove grates, and more
particularly to the backs of such grates or fire places.
The chief object of the invention is to enable the heat of the fire to be radiated into
the room, and to be otherwise controlled, in a very simple and effective manner.
And in order that my invention may be clearly understood, I annex a sheet of
drawings of same, the same letters of referance indicate similar parts in either of the
figures.
Fig. 1, a cross sectional elevation of a stove grate made according to my invention.
Fig. 2, a front view of same.
In carrying out my invention in an ordinary stove grate, for example such as
shown in the drawings, I construct a metallic back plate or radiator A somewhat
similar to an ordinary fall door, having its axis B, placed upon its lower edge, and its
top edge is arranged to rest against the inside of the stove front C, or an adjustable
screw D, and against the back, as the extreme limits of its movement, or to stop or
remain stationary at any intermediate point.
I prefer to make the axis B or that part on which the plate or radiator turns in the
form of a solid roller, fitting into a semicircular_groove E, placed horizontally above
and upon the top edge of the firebrick back F, (or thereabouts,) so that when the
open, and when
radiator plate A is upright, the chimney aperture or flue is wide
brought forward to the extent of its movement, and resting with its edge against the
front of the stove C or screw D the chimney or flue is closed.
The radiator plate A is provided with a series of openings or slots G for the smoke
and products of combustion to pass through, and these may be closed when desired by
means of a sliding plate H at the back of the radiator.
I prefer to make the smoke openings G in the radiator A in the shape of long
vertical slots; for example I find that five of such slots of three quarters of an inch
wide, answer well in a stove of ordinary size, especially if the radiator is also raised
about an inch from the front plate C.
When the fire is well lighted the radiator is closed against the front plate of stove
and the slots opened to permit the passage of smoke, or the top edge of the radiator
may be held a short distance from the stove front plate by the set screw D, thus while
allowing the smoke to escape to the flue, the heat from the fire is thrown by radiation
into the room.
When the radiator A is closed against the front plate the angle of its face shoul
be about forty five degrees or thereabouts, but I do not bind myself to any particula

page_text: A setscrew D for adjusting the opening between the front plate and the radiator A
may be fixed to the front plate if desired.
When fires are not required it is intended to shut down the radiator A against the
front plate C, and to close the slots G so as to prevent dirt or soot from the Chimney
entering the room, but if ventilation is required, the sliding plate H is drawn on one
side, and the vertical slots opened to any desired extent.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed, I declare that what I claim is :-
The combination with a stove grate or fire place a metallic backplate or radiator A
having slots G for the passage of smoke, which can be opened and closed by a sliding
back plate H, and so constructed that it can be turned upon its lower edge to any
desired angle between its limit of movement, for the purpose specified and substantially
as herein-before described and illustrated.
