IMPROVEMENTS IN TANKS FOR MELTING GLASS
Year: 1883

page_text: LETTERS PATENT to Edward Brooke of The Fieldhouse Fire Clay Works,
Huddersfield in the County of York-for an Invention of "IMPROVEMENTS IN
TANKS FOR MELTING GLASS"
PROVISIONAL SPECIFICATION left by the said Edward Brooke at the Office
of the Commissioners of Patents on the 21st June 1883.
EDWARD BROOKE of The Fieldhouse Fire Clay Works, Huddersfield in the
County of York. "IMPROVEMENTS IN TANKS FOR MELTING GLASS'
"
This Invention has reference to furnaces or tanks for melting glass.
Hitherto the whole thickness of the walls forming the bottons and sides of these
tanks have been composed of large slabs or blocks, made of the best fire clay, but
notwithstanding the thickness of the slabs, the heat of the flames and melted glass,
very soon destroys the internal parts of the tank, rendering it unfit for further use,
whilst the outside of the said slabs, although untouched by the heat, are rendered
worthless same as the inside
The object of my Invention is to reduce the first cost of the construction of such
tanks, which 1 accomplish by constructing them of two thicknesses of slabs or
blocks, instead of in one block as is now the case-The bottom of the furnace is
composed of two layers, divided longitudinally, whilst the sides which are also
composed of two layers, are divided vertically, in such caso the inner block
is composed of the best fire resisting material, whilst the outer blocks or bricks
are composed of an inferior fire clay, so that when the inner blocks are destroyed
and the tank rendered unfit for further use, the waste in the unconsumed blocks
is very much less than is the case with the present construction of tanks. By con-
structing glass tanks on the system herein mentioned, they are very much reduced
in cost, without lessening their efficiency.

the said Edward Brooke in the Great Seal Patent Office on the 21st December

EDWARD BROOKE of The Fieldhouse Fire Clay Works, Huddersfield in the
County of York "IMPROVEMENTS IN TANKS FOR MELTING GLASS"
This Invention has reference to furnaces or tanks for melting glass.
Hitherto the whole thickness of the walls forming the bottoms and sides of these
tanks have been composed of large slabs or blocks made of the best fire clay, but
notwithstanding the thickness of the slabs, the heat of the flames.and melted glass
very soon destroys the internal parts of the tank, rendering it unfit for use, whilst
the outside of the said slabs, although untouched by the heat, are rendered
worthless same as the inside.
The object of my Invention is to reduce the first cost of construction of such
tanks and yet obtain the same durability; which I accomplish by constructing
them of two thicknesses of slabs or blocks instead of in one block as is now tho
case. The bottom of the furnace is composed of two layers, divided longitudinally,
whilst the sides which are also composed of two layers are divided vertically, in
which case the inner block is composed of the best refésisting material; whilst
the outer blocks or bricks are composed of an inferior fire clay, so that when the
inner blocks are destroyed and the tank rendered unfit for further use, the waste
in the unconsumed blocks is very much less than is the case with the present
construction of tanks.
The Invention will be better understood on reference to the accompanying
Drawings wherein Fig 1 is section of bottom and sides of a glass tank constructed
according to my Invention. .
The inner part of the tank is built of bricks or slabs A composed of the best fire
clay or the most refractory material, whilst the outer part of the tank is built of
bricks or slabs B composed of an inferior or less refractory material.
Fig 2 is section of another form of glass tank constructed with binder bottom,
having parts A and B as previously explained.
By constructing glass tanks on the system herein mentioned they are very much
reduced in cost, without lessening their efficiency.
Having now described my Invention and. the manner in which the same is to be
performed, I would have it understood that I do not confine myself to any
particular form or construction of tank as the form thereof constitutes no part
of my Invention, but what I believe to be new and therefore claim is
The building or constructing of glass tanks, having the inner parts composed of
a more refractory material than the outer parts, in manner substantially as herein
described.
In witness whereof I the said Edward Brooke have hereunto set my hand and
seal this twenty first day of November in the year of our Lord One thousand, eight
hundred and eighty three.
