PROVISIONAL SPECIFICATION.
Improvements in and relating to Domestic Fire Grates.
I, WILLIAM ALLARDICE, of Bond Street, Belfast, Agent do hereby declare
the nature of this invention to be as follows :—
The contrivance according to my invention is devised with a view to ensure the
consumption of smoke and gases arising from the grate before reaching the
chimney.
In accordance with my invention I make up a fire grate, in the shape of a box,
having a top as well as a bottom part; the two sides of same are made of sheet
iron or any other suitable metal, whilst the front as well as the back, are made up
of ordinary fire bars. The top and bottom of the grate consist of metal bars
placed closer together than the back and front sides thereof, such as those used in
the bottom of grates now in use. One end of the top and bottom doors of the
grate above mentioned, is hinged to either the back or front side thereof; and the
doors are also provided with suitable catches, for fastening same to either the back
or front side of the grate above mentioned.
I mount upon the outer side of each of the sides of the grate, a metal stud for
carrying the same, in suitable bearings. At the end of one of these studs is
mounted a disc or drum, having two insertions cut therein opposite each other.
A lever is fitted to the grate; one end of same fits into one of the insertions cut in
the disc or drum above mentioned, whilst the other end is provided with a knob' or
handle.
A grate constructed in accordance with my invention is operated in the following
manner; that is to say-Supposing the grate is going to be replenished with more
fuel, the top door is opened, and the fuel placed in, in the usual way upon the other,
already lighted fuel,, the top door is then shut down again. The operator then
presses the knob or handle on the lever above mentioned, which releases the drum,
and allows a half turn being given to the grate, thus causing all the smoke and
gases arising from the newly added fuel (which is now at the bottom of the grate)
to pass through the already lighted fuel, and to be consumed before reaching the
chimney.
When desired I may place, in the front of the grate above described an
ornamental detachable stand to give the grate a neater appearance, aud which can
be removed when the grate is required to be cleaned.

Improvements in and relating to Domestic Fire Grates.
I WILLIAM ALLARDICE of Bond Street Belfast in the County of Antrim,
Ireland, Agent 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 :—
The object of this invention is to ensure the consumption of the smoke and gases
arising from the newly added fuel by causing the same to pass through the fuel
which is already incandescent.
Now according to my invention I provide a firebox to contain the fuel in the

page_text: form of a box having two sheet metal sides and the back and front are made up of
ordinary fire bars. The top and bottom of the grate consist of metal bars placed
closer together than the back and front sides thereof, such as those used in the
bottoms of grates now in use. One end of the top and bottom of the grate above
mentioned is hinged to either the back or front side thereof; and the doors so
formed are provided with suitable catches for fastening same to either the back or
front side of the grate above mentioned.
I mount upon the outside of each of the sides of the grate a metal stud or
trunnion for carrying the same in suitable bearings. At the end of one of these
studs is mounted a disc or drum having two notches or slots cut therein opposite
each other. A lever is fitted to the grate; one end of same fits into one of the
slots cut in the disc or drum abovementioned, whilst the other end is provided with
a knob or handle.
A grate constructed in accordance with my invention is operated in the following
manner; that is to say :-Supposing the grate is going to be replenished with more
fuel, the top door is opened and the fuel placed in in the usual way upon the other
already lighted fuel, the top door is then shut down again. The operator then
presses the knob or handle on the lever above mentioned, which releases the drum,
and allows a half turn being given to the grate; thus causing all the smoke and
gases arising from the newly added fuel (which is now at the bottom of the grate) to
pass through the already lighted fuel, and to be consumed before reaching the
chimney.
When desired I may place in the front of the grate above described an
ornamental detachable stand to give the grate a neater appearance and which can
be removed when the grate is required to be cleaned.
And in order that my invention may be fully understood I will proceed to
explain the same with reference to the accompanying drawings in which—
Fig. 1 represents a section of a fire-grate constructed according to this
invention.
Fig. 2 represents a side view of same.
Fig. 3 represents plan of same.
Fig. 4 is a view of the firebox detached from supports.
Fig. 5 is elevation of an ornamental false front on a reduced scale.
The same letters denote the same parts in all the figures.
a a are the sheet metal sides of the firebox 66' trunnions for supporting the
same which rotate in bearings formed in brackets cc' which stand on or are secured
to the hearth stones or tiles.
The top and bottom of the firebox consist of a frame a hinged at e to the back f
or front g of the firebox.
hhh are firebars extending across the frame d. ii are hooks or catches to
secure the top and bottom of the firebox when closed.
k is a lever having a hook at one end thereof the said lever being pivoted at m
to an arm n on the bracket c.
The hook engages with slots n' n' in a disc o attached to the trunnion b.
The front and back of the firebox are formed with bars p. The guard or false
front q shewn in elevation at Fig. 5 is used to give the grate a neat appearance and
may be made.of wire work or bars as shewn the former being preferable if the
grate is used in a nursery or other room to which young children have access in
this case the guard may be continued to the top of the fireplace.
When it is necessary to replenish the fire the top of the firebox is opened fresh
fuel added the top closed and fastened the knobs is depressed raising the hook!
out of engagement with the slot in the disc o and the firebox rotated on its axis
for half a revolution when the incandescent fuel will be uppermost and the gases
and smoke from the green fuel will be consumed during their passage through the
incandescent fuel above it. The firebox is held in its new position by the hook l
engaging alternately with the slots n².

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
-
I. In a firegrate the use of a rotating fire box with an opening at the top and
bottom thereof closed by lids provided with firebars substantially as herein before
specified and for the purpose stated.
11. In a firegrate the combination of a firebox provided with trunnions rotating
in suitable bearings with a locking device for holding the said firebox in any
desired position substantially as hereinbefore described and shewn at Figs. 2 3
and 4.
III. In a firegrate the combination of a rotating firebox having lids provided
with firebars hinged to the top and bottom of the said firebox with a means of
securing the said lids when closed substantially as described and shewn.
