I, EDMUND MALCOLM TURNER, of No. 299, Brockley Road, Brockley, London,
S.E., Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to fire grates of all kinds, but is specially designed for
grates usually known as register stoves.
The invention consists of making the bottom bars of the grate, or some of
them, hollow and open ends and with or without holes in their lengths. They
are fitted together in combination with a hollow back in such a manner that air
can pass through the bars into the back of the grate and from there into the
back of the fire, thus causing the fire to burn very brightly.
A sliding damper may be placed at the outer end of the bars to regulate the
draught through them. At the upper portion of the back of the grate a hollow
heat deflector is fitted. This can be of any desired shape and may be fixed or
be removable. By preference its lower half is made to slope forward towards the
front of the grate, and the upper half to slope back.
An air shaft or passage is carried from any convenient part of the grate, or of
the room in which it is fixed, into the upper hollow deflecting back of the
grate, and the air after being heated there is conducted into the room, preferably
through the upper front part of the grate. A sliding damper may be used to
regulate the supply of heated air from the hollow back.
A separate ventilator of any desired kind is fitted into the front of the grate
above the fire-place and has direct communication with the flue above the fire.
This ventilator can be opened and closed at will, and when open, it will,. by
A suitable pan
supplying air to the flue, reduce the draught through the fire.
or tray is provided to catch falling cinders and the like at the back of the fire.
This ash pan must fit closely to prevent the draught through the grate being
interfered with.

1, EDMUND MALCOLM TURNER, of 299, Brockley Road, Brockley, London,
8.E., Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described in and by the
following statement;-
-
This invention relates to fire grates of all kinds, but is specially designed for

page_text: The invention consists of making the bottom bars of the grate, or some of them,
hollow, and open at both ends and with or without holes in their lengths. They
are fitted together in combination with a hollow back in such a manner that air
can pass through the bars into the back of the grate and from there into the
back of the fire, thus causing the fire to burn very brightly.
A sliding damper may be placed at the outer end of the bars to regulate the
draught through them. At the upper portion of the back of the grate a hollow
heat deflector is fitted. This can be of any desired shape and may be fixed or
removable. By preference its lower half is made to slope forward towards the
front of the grate and the upper half to slope back.
An air shaft or passage is carried from any convenient part of the grate, or of
the room in which it is fixed, into the upper hollow deflecting back of the
grate, and the air after being heated there is conducted into the room preferably
through the upper front part of the grate. A sliding damper may be used to
regulate the supply of heated air from the hollow back.
A separate ventilator of any desired kind is fitted into the front of the grate
above the fire place and has direct communication with the flue above the fire.
This ventilator can be opened and closed at will, and when open it will, by
supplying air to the flue reduce the draught through the fire. A suitable pan or
tray is provided to catch falling cinders and the like at the back of the fire. This
ash pan must fit closely to prevent the draught through the grate being interfered
with.
I will now describe my invention with reference to the accompanying drawings,
in which:
Fig. 1 shews an elevation of a register stove constructed according to my
invention.
Fig. 2 shews an enlarged, sectional side elevation of Fig. 1 on line -
Fig. 3 shows an enlarged sectional plan of Fig. 1. The left hand part repre-
sents a section on line yy, and the right hand part a section on line, both
of Fig. 2.
Fig. 4 shews a sectional elevation of a modified form of deflector.
Figs. 5 and 6 shew sectional views of two modified forms of the ash tray.
Fig. 7 shews the movable tubular grate portion detached and shewing the
supporting legs.
Fig. 8 shews the backing with the grate portion removed.
In the improved stove, the grate portion, the curved back b. and the horizontal
fire bars, are preferably made integral, and the vertical fire bars may be
attached by pins fitting into recesses in the front rail c¹. This method of
construction is to make the cleaning of the air space at the back of the stove
more convenient. The horizontal fire bars are made tubular and open at both
ends. The front ends may be closed by a suitable sliding damper plate & formed
with a corresponding number of orifices, so that the ends of the tubular fire bars
may be closed or left open as preferred. The back ends of the tubular fire bars
open into an air space e at the back of the stove. The air space is shallow in
depth, but extends nearly the whole width of the back of the stove. Its upper
end communicates with the fire at e'. Should ashes or cinders find their way into
the air space, they will fall into the ash pan f, of which one form is shewn in
Fig. 2. The curved back, the horizontal and vertical fire bars and the front
rail may all be supported on legs Fig. 7, or supported from the sides in the
usual way.
When the tubular fire bars and hollow back are heated, air will
be rapidly drawn through the fire bars and air space, and thrown into the back
of the fire, thus improving combustion and consuming smoke.
To ventilate and heat the room, an air inlet is arranged at the lower end of
one of the side jambs g¹ or the fresh air supply may be connected by means of
an air passage with the air outside the room. The inlet y communicates with
an air pipe which leads up to the lower end of the hollow deflector which
slopes forward over, and is heated by the flames from, the fire. The air is

page_text: admitted to the deflector by the inlet , is heated while passing through it, and is
emitted by the exit into and through a further length of piping until it
finally emerges in a heated condition into the room by the exit preferably
formed in the lintel or top jamb of the stove. The inlet g and exit & are pre-
ferably made "grid" fashion and are each provided with a sliding plate to
close them when necessary.
A draught check is also used which opens freely into the chimney and checks
the draught when only a small fire is required.
Referring to Fig. 4, m is a modified form of deflector having an increased
capacity. Either form of deflector may be used and they may be fixed in position,
or left loose for convenience when cleaning the chimney.
Referring to Fig. 5, the modified ash pan is so constructed that the current
of air passing through the fire bars shall not be checked or neutralised by a
lower current, through the front of the ash pan being left partly open.
The
pano shewn in Fig. 6 is smaller and may be substituted for when an open
bottom grate is used and should always be kept tightly closed. In this fig. a
modified shape of air space p is also shewn.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, 1 declare that what
1 claim is:-
-
1. In an improved fire grate the tubular fire bars and air space at the back
of the store, the front ends of the tubular fire bars being preferably fitted with a
sliding damper plate, substantially as herein described and set forth.
2. In an improved fire grate, the deflector sloping out over the fire, and air
pipes in connection therewith, substantially as herein described and set forth.
3. In an improved fire grate the combination of the tubular fire bars, air space
at the back of the stove opening into the fire, the deflectors or m, air pipes in
connection therewith, adjustable inlet and outlet dampers, and ash pan, sub-
stantially as herein described and set forth.
4. The improved fire grate, substantially as shewn and described.
