like Furnaces.
I JOHN WILLIAM WAILES of The Cedars, Bescot, Walsall, in the county of Stafford,
Engineer, do hereby declare the nature of this invention to be as follows:-
The invention relates to open hearth steel melting furnaces or to like furnaces such
as glass tank furnaces having hearth side walls and roof.
The object is to so construct or equip such furnaces that they shall be durable,
more easily repaired, and conveniently renewed in those parts liable to deterioration
.or wear, and inexpensive in maintenance.
The invention consists essentially in carrying the hearth side walls and roof each on
separate supports in such manner that the side walls are quite independant of the
hearth and roof and may be removed without interference therewith. Any spaces
between the side wall hearth and roof are closed when the side walls are in position
by means of a suitable stopping or filling material.
When furnaces are constructed as above I make the parts of the material best
adapted for the purpose. Thus the hearth may be of basic material the side walls of
acid material and the roof of any suitable material.
A further improvement consists in pivotting the supports for the side walls to the
frame carrying the hearth or roof or to independant bearers so that the said side
walls may be readily and freely moved into and out of position.

I JOHN WILLIAM WAILES of The Cedars Bescot Walsall in the county of Stafford
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described.. and ascertained in and by the
following statement :-
The invention relates to open hearth steel melting furnaces or to like furnaces such
as glass tank furnaces having a hearth side walls and roof.
The object is to so construct or equip such furnaces that they shall be durable, more
easily repaired, and conveniently renewed in those parts liable to deterioration or
wear, and inexpensive in maintenance.
The invention consists essentially in carrying side walls on separate supports from
the hearth and roof in such manner that the side walls are quite independent of the
said hearth and roof and may be removed without interference therewith. Any spaces
between the side walls hearth and roof are closed when the side walls are in position
by means of suitable stopping or filling material,
When furnaces are constructed as above I make the parts of the material best
adapted for the purpose. Thus the hearth may be of basic material, the side walls of
acid material, and the roof of any suitable material.
A further improvement consists in pivotting the supports for the side walls, to the
frame carrying the hearth or roof or to independent bearers so that the said side walls
may be readily and freely moved into and out of position.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a longitudinal section, fig. 2 a transverse section fig. 3 a view, half in plan
and half in horizontal section and fig. 4 an end, elevation all of a furnace constructed
in accordance with my invention. a columns, b.girders for carrying the hearth c of
the furnace. d casing surrounding the hearth cand resting on the girders b. e struts
connected to the casing d and to the frame f g roof of furnace resting on the frame f.
h gas ports, i air ports built between the hearth and roof. j air and gas regenerators
and connections. k sides of furnace formed in sections and carried by brackets
provided with arms m pivotted at n to the casing d: The columns a are advantageously
made of cast iron, the girders b of wrought iron or steel; the casing d, struts e, and
frame of cast iron or steel united and held together by tie bolts; the hearth is made
of suitable refractory material having a basic or other lining and the movable sections
ports and roof of silica or acid bricks.
.
Fig. 5 is a front view and fig. 6 a transverse section showing the method of
constructing a movable section above a furnace door. The bracket 1 is shaped so
that the bricks forming the_section_are_disposed as a flat arch and the adjoining
sections are wedge shape so that the weight of the said arch is supported by them.

page_text: The joints between the sides and the hearth are made by ramming in lime and carbon
mixed with tar or the like and the joints between the sides and roof by ramming in
silica.
Iron rods or bars are used during ramming to prevent the filling material from
entering the furnace.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed I declare that what I claim is.
First. Open hearth steel melting and like furnaces with the sides carried
independently of the hearth and the roof.
Second. Open hearth steel melting and like furnaces with movable sides carried
by arms pivotted to suitable supports substantially in the manner and for the purpose
set forth.
