APPARATUS FOR ASBESTOS GAS FIRE
Year: 1884

page_text: I ALFRED CHARLES CHURCHMANN of No 10 Clenston Terrace Munster Road
Fulham in the County of Middlesex Scientific Instrument maker, do hereby
declare the nature of my invention for APPARATUS FOR ASBESTOS GAS FIRE,
to be as follows:-
My invention relates to an improved form of atmospheric burner and apparatus
for a powerful asbestos Gas Fire with power to regulate the saine and to obtain a
more perfect combustion. The construction of my burner and apparatus is as
follows; a piece of 4 or 1in iron tube as long as the grate or stove is wide, with n
number of large holes as outlets for burning, screwed to which is a large circular
or bell shape mixing chamber or atmo to which is fixed the supply Gas nipple
which has three or four small holes so that the gas issues in the mixing chamber
or atmo in separate parts thus causing the air to be drawn into the mixing chamber
or atmo in a larger quantity than usual, it then passes through a diaphragm of
wire gauze or coil of wire (as circumstances require) It is thus easily and well
mixed with perfect security against what is known as the back flash or burning
down the tube.
I attach two or more of the aforesaid burners to an open fire grate or stove
according to the size of room.
For the economizing of the heat and to throw it well out into the middle of the
room and to prevent the destruction of the burners by the heat striking downwards
I have an arrangement of fire clay or other material which consists of a false
bottom and back to be placed in the fire grate which covers the whole of the
bottom and raised in the centre then slanting towards the back which enables me
to place the back burner of burners towards the top, it has a number of holes lin
in diameter corresponding with the holes in the burners, between each hole is
attached a rib piece of fire clay or other material about half an inch high, and of
such a width that it will not allow the lump asbestos to lay in the holes thus
facilitating the progress of the flames among the same and thus causing a greater

page_text: radiation of heat. I have a special arrangement of pipes for supplying the burners
with gas each having a separate tap of its own, so that one or more burners may
be used at the time, thus giving power to regulate the size of the fire and conse-
quently the amount of heat that may be required to raise or lower the temperature
by using one or more burners at a time. All pipes are placed under the floor or 5
tile hearth in which two or three holes about three quarters of an inch in diameter
are made to allow of a metal key to turn them on and off.
An Improved Form of Atmospheric Burner and Apparatus for
a Powerful Asbestos Gas Fire, with Power to Regulate the
same.
ALFRED CHARLES CHURCHMAN of 10 Cleristone Terrace, Munster Road Fulham
in the County of Middlesex, Scientific Instrument Maker do hereby declare the 1
nature of my invention for AN IMPROVED FORM OF ATMOSPHERIC BURNER
& APPARATUS FOR AN ASBESTOS GAS FIRE 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 a new form of Atmospheric Burner with an arrangement 2
for regulating, economising and obtaining a proper mixture of gas and air so as to
obtain perfect combustion and a powerful heat without smell, fumes or anything
unpleasant or injurious to health or cleanliness except the usual products of com-
bustion which are carried off by a small opening into a flue or ventilation pipe
thus saving a large amount of heat without interfering with the Ventilation.

The construction of my Burner is as follows a piece of three quarter of an inch
or inch iron tube as long as the grate or stove is wide with a number of large
holes as outlets for burning, screwed to which is a large circular or Bell shape
mixing chamber or atuno to which is fixed the supply gas nipple which has four
very small holes so that the gas issues into the mixing chamber or atmo in separate 3
parts thus causing the air to be drawn into the mixing chamber or atmo in a larger
quantity than usual, it then passes through a piece of wire gauze or coil of wire as
circumstances require and is thus easily and well mixed with perfect security
against what is known as the back flash or burning down the tube I attach two or
more of the aforesaid burners to an open fire place or stove according to the size of 3

page_text: room and requirements for the economising of hent and to throw it well out into
the room and to prevent the destruction of the burners by the heat striking down-
ward. I have an arrangement of fire clay or any other material which consists of a
false bottom and back placed into the grate or stove which covers the whole of the
bottom and is raised in the centre slanting towards the back which enables me to
place the back burner or burners towards the top thus saving a large quantity of
asbestos as well as heat. The false bottom has a number of holes about one inch
in diameter corresponding to the holes in the burners between each hole a ribbed
piece about half an inch high is attached to prevent the asbestos from laying on the
holes also to allow a free current of warm fresh air to pass under the asbestos thus
facilitating the progress of the flames I have also a special arrangement of pipes
for supplying the burners with gas each having a separate tap of its own so that
one or more burners may be used thus giving power to regulato the size of the fire
to the amount of heat that may be required to raise or lower the temperaturo by
using one or more burners at a time all pipes and taps are placed under the floor
or hearth in which two or three holes are made about three quarters of an inch
diameter to allow of a metal key to reach the taps to turn the gas on and off the
key being separate prevents any one tampering with it. In order that my said
invention may be fully understood and readily carried into effect I describe the
drawings hereto annexed.

fige 6 and 7.
4. A special arrangement of pipes as shewn in drawing marked E. for a more
equal supply of gas to the burners.
5. The construction of an atmospheric gas burner and apparatus for a pure 5
and powerful asbestos gas fire substantially as illustrated in the drawings with
modifications of the same as circumstances may require.
