IMPROVEMENTS IN COMBINED RANGE AND REGISTER GRATES
Year: 1882

page_text: LETTERS PATENT to William Yate Stevens of Thomas Street Bristol in the
county of Gloucester for an Invention of IMPROVEMENTS IN COMBINED
RANGE AND REGISTER GRATES
PROVISIONAL SPECIFICATION left by the said William Yate Stevens at
the Office of the Commissioners of Patents on the 19th September 1882.
WILLIAM YATE STEVENS of Thomas Street Bristol in the county of Gloucester
"IMPROVEMENTS IN COMBINED RANGE AND REGISTER GRATES"
This Invention relates to certain improvements in combined range, stove and
register grates the object being to produce a maximum amount of heat and the
application of the same to the various cooking and heating requirements by an
improved method of burning fuel at a very economical. cost and also at a great
saving of labour and with cleanliness.
The apparatus is constructed as follows:-A cooking range of somewhat ordinary
construction made with a sunk grate between the boiler and oven. The grate has
a solid base ridged on the inner or fire side and perforated with draught holes."
The bottom bar is cast hollow and also perforated on its inner side with small
holes for gas jets and is connected with gas main by pipe and union sockets The
top of the oven is fitted with an atmospheric gas burner and is connected with the
main through the pipe and the hollow bar. The oven is constructed with free
passage for the heat of the grate to surround it
The sunk grate allows for the use of coke instead of coal while the hollow bar
being furnished with gas jets renders the lighting of the fire an automatic process.
A great heat is thus obtained at a very small cost and in cases where the gas
which supplies the atmospheric burner is not of sufficient heat, the heat of the
grate surrounding the oven will supply all deficiency and the heat thus obtained
from coke fire will keep the water in boiler at boiling temperature.

"IMPROVEMENTS IN COMBINED RANGE AND REGISTER GRATES
دو
This invention relates to certain improvements in combined range stove and
Register grates the object being to produce a maximum amount of heat and the
application of the same to the various cooking and heating requirements by an
improved method of burning fuel at a very economical cost and also at a great
saving of labour and with cleanliness.
The apparatus is constructed as follows:-
A cooking range of somewhat ordinary construction is made with a sunk
grate A between the boiler and oven. The grate has a solid base B ridged on the
inner or fire side and perforated with draught holes B¹ more or less as convenient.
The second bar C is cast hollow and perforated on its inner side. with small holes
for gas jets and is connected with gas main by pipe and union sockets D. The top
of the oven E is fitted with atmospheric gas burners F connected with the main
through the pipe D' and the hollow bar C. The oven E is constructed with free
passages for the heat of the grate to surround it.
The sunk grate allows for the use of coke instead of coal whilst the hollow bar
being furnished with gas jets renders the lighting of the fire an automatic process.
A great heat is thus obtained at a very small cost and in cases where the gas which
supplies the atmospheric burners is not of sufficient heat the heat of the grate
surrounding the oven will supply all deficiency and the heat thus obtained from
the coke fire will keep the water in boiler H at boiling temperature and the
oven and fire prepared for culinary purposes.
Air and heat passages to the flues are provided in substantially ordinary manner
with traps or covers as indicated at I, K, M, N.
Having now described the nature and particulars of my said Invention
I claim:
The improved combined range and register grates with the sunk grate A between
oven and boiler with solid grate base B ridged and also perforated at B' with gas
bar C and burners D' F, as herein described in reference to and shown by the
accompanying drawing
In witness whereof I the said William Yate Stevens have hereunto set my
hand and seal this twentieth day of March in the year of our Lord one
thousand eight-hundred and eighty-three.
WILLIAM YATES STEVENS (L.S.)
