Iron and Steel Sheets and other Parts or Articles of Metal.
I, JOB EDWIN EAST, of The Hall, Upper Ettingshall, Deepfields, near Bilston in
the County of Stafford, sheet iron manufacturer, do hereby declare the nature of
this invention to be as follows:-
The covers and dishes usually employed in close annealing iron and steel sheet
(and which are applicable also for annealing other parts or articles of metal) are
made entirely of metal, the covers being usually of thick wrought iron or steel
plates, and the dishes either of such plates or of cast iron. The dishes, also, are
carried to roll upon balls running in channels in the bottom of the furnace. The
first cost of these covers and dishes is considerable, and owing to exposure to the
intense beat from the furnace, they rapidly become distorted and burnt, and require
frequent replacement, and the operation of drawing them out from and replacing
them within the furnace is somewhat tedious, as the channels are liable to become
distorted with the heat and choked with dirt.
Now, the object of this invention is to effect economy in first cost of the covers
and great facility in repairing them, to ensure very greatly increased durability of
both the covers and dishes, and greater facility in drawing such covers and dishes
out of the annealing furnaces and replacing them therein.
According to this invention, the dish forms also the bottom of the annealing
furnace, and consists of a plate, which may be conveniently of cast iron properly
strengthened with ribs on its underside, carried on wheels which run on rails placed
lengthways of the furnace so that it can be readily drawn ont and in by means of a
winch, or in other convenient manner, the upper surface of the said plate being
entirely paved over with fire brick which forms both the floor of the furnace and also
the upper face of the dish. The plate and paving thereon are somewhat wider than
the width of the interior of the furnace, each side edge of the plate and paving being
within a longitudinal groove or recess in the wall of the furnace along which it is
drawn as the dish is moved endways. The doors at each end of the furnace close

page_text: immediately over the top of the paving on the plate. A groove or sinking is formed
in the paving, for the reception of the walls of the cover hereinafter described.
The fire brick paving thoroughly protects the plate, and the air is free to circulate
below the plate and thus keep it cool, and the wheels being conveniently made of a
larger diameter than the balls usually employed to carry a dish, and the rails not
being liable to be choked with dirt as are the channels usually employed, and both
the wheels and rails being practically underneath the furnace, in a current of cool
air, the operation of drawing out the dish and cover from and replacing it within
the furnace is very much facilitated.
The walls of the cover are formed of fire brick slabs rebated together at their
joints, and clamped at the top with metal clips let in flush with the upper edge, or
otherwise jointed and clamped so as to be readily put together and taken apart.
These slabs rest at the bottom within the groove or sinking in the paving of the dish.
The corners may be conveniently formed of slabs angle-shaped on plan. The top
consists of fire brick slabs resting on the edges of the vertical walls, and may be
dowelled or otherwise steadied thereon, if desired. The different joints may be made
up with fire clay, or in any usual or convenient manner, as may be desired.
These fire brick covers are cheaper in first cost, and very considerably more durable,
than the metal covers usually employed in close annealing, and in case of one or
more of the slabs being burnt out such may be readily replaced.
The cover may, if desired, be formed in one piece of fire brick, or with the walls
only in one piece and with a loose top either formed of slabs or in one piece; but
the method of forming the walls and top in slabs, as above described, permits of the
parts being readily taken to pieces instead of the whole cover having to be lifted,
and permits also of ready repair.

Iron and Steel Sheets and other Parts or Articles of Metal.
I, JOB EDWIN EAST, of the Hall, Upper Ettingshall, Deepfields, near Bilston in
the County of Stafford, sheet iron manufacturer, 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, reference being had to
the accompanying drawings, and the letters of reference marked thereon (that is
to say):
:-
The covers and dishes usually employed in close-annealing iron and steel sheets
(and which are applicable also for annealing other parts or articles of metal) are
made entirely of metal, the covers being usually of thick wrought iron or steel
plates, and the dishes either of such plates or of cast iron. The dishes, also, are
carried to roll upon balls running in channels in the bottom of the furnace. The
first cost of these covers and dishes is considerable, and owing to exposure to the
intense heat of the furnace, they rapidly become distorted and burnt, and require
frequent replacement, and the operation of drawing them out from and replacing
them within the furnace is somewhat tedious, as the channels are liable to become
distorted with the heat and choked with dirt.
Now, the object of this invention is to effect economy in first cost of the covers
and great facility in repairing them, to ensure very greatly increased durability of
both the covers and dishes, and greater facility in drawing such covers and dishes
out of the annealing furnace and replacing them therein.
According to this invention, the dish is constructed as a movable platform which
forms also the bottom or part of the bottom of the annealing furnace, and consists of
a plate, which may be conveniently of cast iron properly strengthened with ribs on
its underside, carried on wheels which run on rails placed within a pit in the bottom
of the furnace so that it can be readily drawn out and in by means of a winch, or
in other convenient manner, the upper surface of the said plate being entirely paved
over with fire brick or other refractory material. The fire brick paving thoroughly
protects the plate, and the air is free to circulate below the plate and thus keep it
cool, and the wheels being conveniently made of a larger diameter than the balls
usually employed to carry a dish, and the rails not being liable to be choked with
dirt as are the channels usually employed, and both the wheels and rails being
practically underneath the furnace, in a current of cool air, the operation of drawing
out the dish and cover from and replacing it within the furnace is very much
facilitated.
The walls of the cover are formed of slabs of fire-brick or other refractory
material, resting upon the paving of the plate and rebated together, and they may if
desired be clamped at the top with metal clips let in flush with the upper edge, or be
otherwise jointed and clamped so as to be readily put together and taken apart. The

page_text: top is formed of similar slabs resting on the edges of the vertical walls. The different
joints such as those of the paving on the plate with the floor or sides of the furnace
and of the slabs forming the cover, may be made up with fire-clay, or in any usual or
convenient manner, as may be desired.
These fire brick covers are cheaper in first cost, and very considerably more durable
than the metal covers usually employed in close-annealing, and in case of one or
more of the slabs being burnt out such may be readily replaced.
Referring to the drawings herewith, figure one is a transverse section through a
furnace and cover and dish, constructed according to this invention, specially for
employment in close-annealing iron and steel sheets; figure 2 is a longitudinal
section taken on line xx of figure 1, looking in the direction of the arrow a; and
figure 3 is a detached sectional plan of the cover. The same letters of reference
occuring upon two or all of these views indicate corresponding parts. A pit A is
formed down the middle of the bed B B of the furnace C, and a plate 6 mounted on
wheels c
c etc. is made capable of being run into and out of the bottom of the
furnace on rails d d. This plate is suitably strengthened by ribs e e etc. and is
paved on the top with a fire-brick paving f. The top of the paving fis level, or
approximately so, with the floor of the furnace on each side and forms, in effect, the
middle portion of the floor. The side edges of the paving fare rebated, as shewn, to
run under ledges of firebrick g g projecting from the upper edges of the pit A. The
doors GG of the furnace are of the usual character and are raised and lowered in
grooves in the usual manner, the lower ends of the doors when down bedding upon
the upper surface of the paving f and of the bottom of the furnace on each side
thereof. The furnace is shewn by figure 2 to be constructed so that the plate b with
the paving thereon may be run clear through the furnace, if desired; but the furnace
may, of course, be formed with one end wall if desired, in which case the plate with
the paving thereon could be run in and out from one end of the furnace only. In
such case the inner end of the paving f may be rebated as at the sides to fit under a
projection from the end wall, and it is preferred to form an opening through such
wall at the end of the pit A to allow of a current of air constantly passing under
the plate. The walls of the cover E are formed of firebrick slabs ii etc. (say about
three inches in thickness) resting at their lower edges upon the surface of the
paving, and rebated together at their vertical joints as shewn by figure 3. The
corners may be conveniently formed of slabs angle-shaped on plan, as shewn by
figure 3. These slabs, when put together with fire-clay and with the top placed
thereon, will usually be found to hold themselves in position without the employment
of clips or analagous devices, but it is preferred to employ clips so as to avoid any
risk of the slabs being moved out of position by the action of the heat, or otherwise.
A suitable clip (k) for the purpose is shewn to an enlarged scale in edgeway view by
figure 4, and in side elevation by figure 5, as in position at the top of a joint between
two slabs. The clip is let into the top edges of the slabs so as to be flush therewith,
and passes down a short distance on each side of each slab. The clips are readily
removed when it is desired to remove the slabs. The top of the cover consists of
fire-brick slabs resting on the edges of the vertical slabs and rebated together at
their transverse joints. No clips are required for the top slabs. If the furnace C is
of considerable length, as shewn in the illustrations, with the plate with the
paving thereon arranged to be run in and out lengthways of the furnace, two
grates D D may be arranged on one side of the furnace, but the invention is not
limited to any shape of furnace or arrangement of grate or grates therewith, as any
usual or convenient shape of furnace and arrangement of grate or grates therewith
may be employed, the width and length of the plate 6 with the paving thereon and
the dimensions of the cover E being, of course, such as to suit the special purpose
for and conditions under which the plate and cover are employed. The flues from the
furnace C may be of any usual or convenient character. In the illustrations they
are shewn as downward flues ; communicating with a longitudinal flue F in the
bed of the furnace, such flue F, of course, communicating with the chimney
stack.

page_text: The cover may, if desired, be formed in one piece of fire brick, or with the walls
only in one piece, and with a loose top either formed of slabs or in one piece, and the
top may, of course, be formed in one piece, though the sides are composed of slabs;
but the method of forming the walls and top in slabs, as above described, permits of
the parts being readily taken to pieces instead of the whole cover or the whole cover
without the top having to be lifted as a single piece, and permits also of ready
repair.
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 in respect of means or appliances for employment in close annealing iron
and steel sheets, and other parts or articles of metal, is :-
1. The improvements therein substantially as herein described and shewn by the
drawings herewith, for the purposes set forth.
2. A platform capable of being readily run into and out of the furnace and
