Sealed the 24th September 1867, and dated the-29th-March 1867.
PROVISIONAL SPECIFICATION left by the said Edwin William Ball at
the Office of the Commissioners of Patents, with his Petition, on the
29th March 1867.
:I, EDWIN. WILLIAM BALL, of Birmingham, in the County of Warwick,
"IM
Manufacturer, do hereby declare the nature of the said Invention for
PROVEMENTS IN GAS FIRE-PLACES AND GAS STOVES AND IN APPARATUS FOR HEATING
CONSERVATORIES AND OTHER ROOMs," to be as follows:-
L
'My Invention consists, firstly, of the arrangement herein-after described of
parts of gas fire-places and gas stoves for the purpose of heating to bright
redness in an ordinary open fire-grate or in an ordinary stove pieces of pumice-
stone, plumbago, fire-clay, asbestos, or other solid material not injuriously
Affected by heat.
In carrying into effect this part of my Invention I arrange a series of gas
burners of the kind called Bunsen's burners on a supply pipe at such a distance

page_text: apart that the said burners may pass between the bars of the bottom of
the fire-grate or stove so as to deliver a mixture of air and inflammable gas
or vapour into the interior of the grate or stove. The said gaseous mixture
when ignited plays among the pieces of pumicestone or other solid with which
the grate is filled and heats them to redness giving the appearance of a glowing
fire and radiating a large amount of heat into the room. The said Bunsen's
burners consist of tubes into which inflammable gas or vapour is delivered,
and having holes at their lower ends through which atmospheric air may enter
and mix with the gas or vapour. The gaseous mixture burns without smoke
and gives out a large amount of heat. I prefer to use pieces of pumicestone
or other solid of a size about equal to that of a walnut, but I do not limit
myself thereto. When the spaces between the bottom bars of the grate or
stove are narrow I prefer to replace the said bars by bars having wide spaces
between them so as to admit burners of sufficiently large diameter.
My Invention consists, secondly, of the following arrangement for heating
the water pipes in conservatories and other rooms. I employ one or a series
of the Bunsen's burners herein-before referred to and arrange them in a
vertical tubular boiler so that when the apparatus is in use the flame and
heated air produced by the combustion of the gaseous mixture ascend through
the said boiler and descend outside of it and between it and a fire-clay jacket
or case, the products of combustion being conveyed away by means of piping
which may be carried along the floor of the conservatory or room so as to
economize the heat. The arrangement of the water pipes is of the ordinary
kind.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edwin William Ball in the Great Seal Patent Office on
the 26th September 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME I, EDWIN
WILLIAM BALL, of Birmingham, in the County of Warwick, Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of March, in the year of our
Lord One thousand eight hundred and sixty-seven, in the thirtieth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Edwin William Ball, Her special licence that I, the said Edwin
William Ball, my executors, administrators, and assigns, or such others as

page_text: I, the said Edwin William Ball, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel. Islands, and Isle of Man, an Invention for "IM.
PROVEMENTS IN GAS FIRE-PLACES AND GAS STOVES AND IN APPARATUS FOR HEATING
CONSERVATORIES AND OTHER ROOMS," upon the condition (amongst others) that
I, the said Edwin William Ball, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edwin William Ball, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:--
My Invention consists, firstly, of the arrangement herein-after described of
the parts of gas fire-places and gas stoves for the purpose of heating to bright
redness in an ordinary open fire-grate or in an ordinary stove pieces of
prepared pumice-stone, plumbago, fire-clay, asbestos, or other solid material
not injuriously affected by heat.
In carrying into effect this part of my Invention I arrange a series of
improved gas burners of the kind called Bunsen's burners on a supply pipe,
at such a distance apart that the flame from the said burners may pass
between the bars of the bottom of the fire-grate or stove, so as to deliver a
mixture of air and inflammable gas or vapour into the interior of the grate or
stove. The said gaseous mixture when ignited plays among the pieces of
prepared pumicestone or other solid with which the grate is filled. and heats
them to redness, giving the appearance of a glowing fire and radiating a large
amount of heat into the room. The said Bunsen's burners consist of tubes
into which inflammable gas or vapour is delivered, and having holes at their
lower ends through which atmospheric air may enter and mix with the gas or
vapour. The gaseous mixture burns without smoke and gives out a large
amount of heat. I prefer to use pieces of pumicestone or other solid of a
size about equal to that of a walnut, but I do not limit myself thereto. When
the spaces between the bottom bars of the grate or stove are narrow I prefer
to replace the said bars by bars having wide spaces between them so as to
admit burners of sufficiently large diameter.

page_text: My Invention consists, secondly, of the following arrangements for heating
the water pipes in conservatories and other rooms:-I employ one or a series
of the Bunsen's burners herein-before referred to, and arrange them in a
vertical tubular boiler, so that when the apparatus is in use the flame and
heated air produced by the combustion of the gaseous mixture ascend through
the said boiler, and descend outside of it and between it and a fire-clay jacket
or case, the products being conveyed away by means of piping, which may be
carried along the floor of the conservatory or room so as to utilize the heat.
The arrangement of the water pipes is of the ordinary kind.
Having explained the nature of my Invention I will proceed to describe,
with reference to the accompanying Drawing, the manner in which the same
is to be performed.
Figure 1 represents in front elevation an open stove constructed according
to my Invention. a, a, a, are improved Bunsen's burners supplied with coal,
gas, or other inflammable gas or vapour from the gas pipes b, b. The pipe b
supplies gas or vapour to two of the said burners, and the pipe be supplies gas
or vapour to the other burner; each pipe is furnished with a tap 63, b'. When
a less amount of heat is required than that produced by three burners the
supply of gas or vapour is wholly cut off from one of the burners by closing
the tap b; and when a further reduction of heat is required the tap b' is
wholly closed and the gas or vapour cut off from two of the burners; the
stop cock or tap b being reopened so as to supply gas or vapour to one burner
only. The full stream of gas or vapour must be supplied to the burners
in the manner described to ensure the efficient action of the said burners.
The said burners a, a, a, are connected together by the tubular connector c.
d, d, d, are the stove bars, and e lumps of prepared pumicestone supported on
the bottom of the grate. The tops of the burners a, a, a, may either be
situated a short distance below the bottom of the grate or introduced between
the bars of the grate so as to come into contact with the pumicestone e.
When the taps 63, 64, are opened and the gaseous mixture is ignited at the
top of the burners the flame plays among the lumps of the prepared pumice-
stone c, heating them to bright redness and causing them to radiate heat and
light into the apartment in which the stove is situated. The burners a, a, a,
are represented of full size in Figures 2 and 3, Figure 2 representing them in
elevation (partly in section), and Figure 3 representing them in plan together
with the connector c. Each of the said burners consists of a chamber f
supplied with gas or vapour from the pipe g, the said chambers being
surmounted by the corrugated crinkles h, h, h; the shape of the crinkles h, h, h,
is best seen in the plan, Figure 3. Holes i are made in the chambers f,

page_text: through which holes atmospheric air enters and mixes with the gas or vapour
supplied by the pipes g. The mixture of gas and air escaping from the tops
of the crinkles h on being ignited yields a large and smokeless flame of great
heating power. Instead of the crinkles or corrugated tubes h, h, straight or
plain tubes open at top may be substituted therefor, but diminished heat
results from the use of the said straight or plain tubes; and instead of using
three burners five or more burners may be employed where necessary.
Although I prefer the form of Bunsen's burner described and represented,
yet I do not limit myself thereto, as other forms of burner for burning a
mixture of gas and atmospheric air may be employed with the same or nearly
the same effect.
The arrangement of parts described and represented are applicable to open
fire-grates and stoves of various constructions.
Figure 4 represents in vertical section and Figure 5 in plan that part of
my Invention which relates to heating the water pipes or boilers in conserva-
tories and other rooms.
In the accompanying Drawing I have illustrated this part of my Invention
as applied to the heating of a boiler for a conservatory, but in place of a
boiler a coil of piping may be substituted without any other change in the
arrangement represented. k, k, k, are the burners (three or more of which
may be used) of the kind described with reference to Figures 1, 2, and 3;
I is a boiler consisting of a double hollow cylinder, the annular space between
the cylinders containing the water to be heated. In the cylindrical space m,
constituting the furnace, two layers of prepared pumicestone n are situated,
one at the bottom and the other near the middle. The pumicestone is supported
on gratings m, m2. Both the layers of pumicestone become heated by the
flames from the burners k, k, k, and the products of combustion after passing
out at the top of the centre space or furnace m pass down the outside of the
boiler and along the horizontal flue g to the chimney p; the horizontal flue g
may be of a length to pass under the floor of the conservatory or room before
opening into the flue or chimney p. The pumicestone I employ may be
ordinary pumicestone broken into fragments of convenient size, but before
employing it in carrying my Invention into effect I prefer to soak it in a
solution consisting of one part by weight of chloride of cobalt, one part by
weight of chloride of manganese, two parts by weight of nitrate of potash,
and twenty parts by weight of water, or such other proportions as will pro-
duce the black oxides of cobalt, and manganese. Instead of pumicestone
plumbago, fire-clay, asbestos, or other solid material not injuriously affected
by heat may be employed,

page_text: Having now described the nature of my Invention, and the manner in
which the same is to be performed, I wish it to be understood that I do not
limit myself to the precise details herein described and illustrated, as the same
may be varied without departing from the nature of my Invention; but I
claim as my Invention,-
Firstly, the improvements in gas fire-places and gas stoves herein-before
described and illustrated in the accompanying Drawing, that is to say,
applying to or combining with open fire-places and open stoves, substantially
as described and illustrated, a series of Bunsen's gas burners or other burners
burning a mixture of gas or inflammable vapour and atmospheric air for the
purpose of heating to bright redness pieces of pumicestone, plumbago, or
other solid not injuriously affected by heat, with which solid the grate or stove
is filled or partly filled.
Secondly, the improvements in apparatus for heating the water pipes.
or boilers of conservatories and other rooms herein-before described and
illustrated in the accompanying Drawing, that is to say, applying to or com-
bining with a boiler of the construction described and represented, or a coil
of pipes, one or a series of Bunsen's gas burners, or other similar burners,
for the purpose of heating the water in the said boiler or coil of pipes.
In witness whereof, I, the said Edwin William Ball have hereunto set
my hand and seal, this Twenty-third day of September, in the year of
our Lord One thousand eight hundred and sixty-seven.
Witness,
GEORGE SHAW.
