AN IMPROVED CONSTRUCTION OF TANK FOR MELTING GLASS
Year: 1884

page_text: I, EDWARD BROOKE of the Field House Fire Clay Works Huddersfield,
Yorkshire, Fire Brick and Sanitary Tube Manufacturer do hereby declare the
nature of my invention for "AN IMPROVED CONSTRUCTION OF TANK FOR MELTING
GLASS" to be as follows:-
My improvements consist in a new method of constructing tanks for melting
glass, such tanks having hitherto been made with hollow bottoms under which
cold air is caused to travel for the purpose of keeping the bottom of the tank, cool,
and thereby prevent the molten glass from destroying the tank and escaping
therefrom through the bottom.
.
Glass melting tanks have also been made with solid bottoms, but owing to the
faulty construction thereof, or the quarries of which the bottoms are made; the
molten glass soon penetrates between the joints and in getting behind the blocks,
loosens and lifts them up, sometimes causing them to float in the metal and
thereby destroy the tank.
My invention consists in constructing the bottoms of such tanks, in a concave
form, composed of blocks or fire bricks, made to a proper radius, and so constructed
that the blocks or bricks form an accurately fitting concave arch, which effectually
prevents the said blocks from rising up and floating amongst the metal.
These blocks I prefer to place on a bed of sand, to form a solid bottom.

page_text: COMPLETE SPECIFICATION.
I EDWARD BROOKE of the Field House Fire Clay Works, Huddersfield,
Yorkshire do hereby declare the nature of my invention for "AN IMPROVED
CONSTRUCTION OF TANK FOR MELTING GLASS" and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
My improvements consist in a new method of constructing tanks for melting
glass, such tanks having hitherto been made with hollow bottoms, under which
cold air is caused to travel for the purpose of keeping the bottom of the tank cool,
and thereby prevent the molten glass from destroying the tank and escaping
therefrom through the bottom.
Glass melting tanks have also been made with solid bottoms, but owing to the
faulty construction thereof, or the quarries of which the bottoms are made the
molten glass soon penetrates between the joints and in getting behind the blocks
loosens and lifts them up sometimes causing them to float in the metal and thereby
destroy the tank.
My invention consists in constructing the bottoms of such tanks in a concave
form, composed of blocks or fire bricks made to a proper radius, and so constructed
that the blocks or bricks form an accurately fitting arch which effectually prevents
the said blocks from rising up and floating amongst the metal.
Those blocks I prefer to place on a bed of sand to form a solid bottom.
In order that this Invention may be better understood I herein give reference to
the accompanying sheet of drawings wherein Figs. 1 and 2 are cross sections of a
glass smelting tank. A is the top of the tank, and B the bottom thereof which is
made concave according to my invention.
The blocks or fire bricks forming the concave bottom are preferably placed as
shown in the drawings, and they are laid upon a bed of sand C so as to form a
solid bottom.
The construction of tanks with concave bottoms in the manner herein shewn are
much more durable than those at present in use as their peculiar formation renders
them less liable to be destroyed by the action of the melted glass.
"
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
Firstly. The formation of glass melting tanks having concave bottoms substan-
tially as herein shewn and described.
Secondly. The construction of glass smelting tanks having concave bottoms
resting upon a bed of sand in manner substantially as shown.
Dated this 27th day of July 1885.
