do hereby declare the nature of this invention to be as follows:-
Furnace door to be used for Mill, Gas, or any other such Furnaces. The Inven-
tion consists of a Furnace Door made from Fireclay. The Door can be brought
into its proper position by the use of two pieces of Iron, which slide in the centre
of the Door, and are connected with the Gland at the top of the Door, and also have
a swivel in the middle of the latter and hoth, i.e. the Door, and the two pieces
of iron are connected together by means of two Cotters. My Furnace Door has "
perforated holes which causes the air to travel through the centre of the Door, so
that whilst one side of the Door is nearest to the fire, the other side is being kept
cooled so that when one side has been used, the other which has been keep in a
cooled state can be reversed, nearest to the Furnace for use, by simply turning the
Door round, which can be done through the action of the swivel at its top and
mentioned above.
Again after the door has been used both sides, at one end, my principle of perfor-
ated holes also allows, if required, of the other end on both sides being used, and
these ends can be brought into proper position by merely 'reversing the iron-work
at the bottom of the Door.

COMPLETE SPECIFICATION.
Furnace Door.
HENRY SIMCOX (Senior) 37 New Street West Bromwich Engineer do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
Furnace Door to be used for Mill, Gas, or any such Furnaces.
The invention in question consists of a Furnace Door made from Fire-clay.
The Furnace Door can be brought into its proper position by the use of a piece
of Iron (C) which can slide in the centre of the Door, and is connected with the
Gland (B) at the top of the Door, and also has a Swivel (A) in the middle of the
latter, and both, that is to say, the piece of Iron, and the Door, are connected
together by means of two Cotters (D).
My Furnace Door has perforated holes (E) each inch round, which causes the

page_text: air to travel through the centro of the Door, thereby whilst one side is next to the
fire, the other side of the Door is being kept in a cool state, so that when one side
has been used, the other that has been kept cool can be reversed nearest to the
Furnace for use, simply by turning the Door round, which can be done through
the action of the Swivel (A) at.its top. The Swivel in question, being hung on
a Hook affixed to Chain, or a lever.
Again after the Door has been used both sides at one end, my principle of perfor-
ated holes (E), also allows, if required, of the other end on both sides of the Door
being used, and the ends of it can be put into the position for this purpose, by
merely reversing the Iron-work (C) from the top F of the Door to the bottom Ġ
of same.
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.
1st The Furnace Door having perforated holes (E) through it, that is to, say,
from the top to the bottom, and also through each side, is kept cool, so that after
the side of the Door nearest to the Furnace fire has been worn out it can by simply
being turned round be rendered equivalent to 'the renewal of a new Iron Door,
. furthermore after both sides of the Door have been' worn; it can be used again by
reversing it to the other end if required.
2- The Ironwork (C) used with the Furnace Door, slides up either end of the
Door for quite 2 inches from the bottom end, so that it is utterly impossible for
"the fire to burn or injure same.
3rd The Door itself being prepared from Clay of a special quality is fire resisting,
and effects a saving in the cost, of more than 75 per cent, in comparison with the
Tron Doors with Fire bricks'affixed on the inside of same, as hithereto'used in Gas,
Mill, and other such Furnaces.
