PROVISIONAL SPECIFICATION.
Improvements in Kilns for Burning Retorts, Pipes, Quarries, and
other Refractory Substances.
I JOSEPH MORTON of Cinder Hills, Halifax, in the County of York, Brick
Manufacturer, do hereby declare the nature of this invention to be as follows:-
:-
My said invention relates principally to kilns used for burning retorts, pipes, or
large fireclay lumps, but my said invention is also applicable to the manufacture of
large bricks, or other less bulky fireclay or other goods.
"
The said invention consists in the construction & arrangement of the kiln
herein-after described, whereby the handling of the material in the " green or
unburnt state is done much easier, & more expeditiously carried out, particularly as
regards retorts or sanitary tubes.
For effecting this purpose I construct the kiln with a loose stop or roof, the said
roof being formed in sections in the following way. I employ an iron frame con-
sisting of two springer beams, these beams being tied together by two arch plates
or distance pieces corresponding with the width of the kiln roof.
These arch plates I make preferably of an inverted T section.
In building up these roof sections, I first line the springer beams with bricks,
made to the proper angle for taking the thrust of the arch bricks, I then slide
special arch bricks onto the inverted T section arch plates, the bricks being
specially prepared with a slot for this purpose.
By this means I have a double security against the arch or roof crushing or
falling in, as the arch being built from springers is self supporting as in any common
arch, together with the additional security obtained by having the bricks also hung
on the arch plates by means of the T slots.
By the method of construction described above, all the iron framework upon
which the arch is built is protected from the direct action of the fire.
In an ordinary size kiln I employ about ten roof sections, placing them
side by side & luting the joints to prevent the access of cold air to the body of
the kiln.
By removing these sections I have free access to any part of the kiln with the
overhead travelling crane usually employed to fill & discharge, whereby the
handling of the goods, particularly in the green or unburnt state is greatly facili-
tated & this applies more particularly to retorts or goods of a like nature which
are difficult to handle particularly in a closed top kiln.

COMPLETE SPECIFICATION.
Improvements in Kilns for Burning Retorts, Pipes, Quarries, and
other Refractory Substances.
I, JOSEPH MORTON of Cinder Hills, Halifax, in the County of York, Brick
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 :-
This invention relates to a new construction of kiln to be used for burning
retorts, pipes, fire clay slabs, but the newly constructed kiln may also be used to
burn bricks or other fire clay articles.

page_text: In order that my invention may be more clearly understood I will make reference
to the accompanying sheet of drawings illustrative thereof wherein
Fig. 1 is a vertical section of my improved kiln and
Fig. 2 is another vertical section taken through the line 1 and 2 of Fig. 1.
A represents the outer sides of the kiln and B represents the furnace openings.
The heat and gases from the fires pass up the flues C as indicated by the several
arrows and impinges against the retorts D or other articles placed within the kiln
the said gases escaping through the floor E which for that purpose is composed of
a suitable form of grating. The primary part of my invention however has
reference to the roof and consists in a new method of covering in the roof or top
of the kiln and this comprises a suitable number of sections or arches as indicated
in Figs. 1 and 2. Each section is composed of two springer beams F (see enlarged
views Figs. 3 and 4) each end of which are connected by bolts G to angle iron
shaped plates H and from these the archways are built up and composed of fire
brick slabs I each of which have formed on their upper surfaces notches or slots J
(see Figs. 2 and 5 for taking hold of the flange L projecting from the inner side
of the springer beams F such said springer beams being tied together by the tie-
rod M which is made with a loop by which to lift the arch. It will be seen that
by covering in the roof of a kiln by segmental arches as shewn and described that
all the ironwork is outside the kiln and free from the direct action of the fire,
whilst by means of a travelling overhead crane the several sections or arches can
be lifted and put on one side so as to uncover the kiln, thereby permitting free
access thereto, enabling the workman to quickly remove the retorts or other
articles which have been burnt and also to quickly recharge the kiln, after which
the sections or arches can be quickly put back and the process of burning resumed.
It will therefore be seen that by constructing a kiln in the manner described that
the retorts or other articles can be placed in and out with very little handling and
this is a considerable advantage upon the articles are "green
or unburnt.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
-
Firstly. In kilns for burning retorts and other descriptions of fire clay goods,
the construction and use of moveable archways or sections employed in the manner
and for the purpose as substantially herein shewn and described.
Secondly. In kilns for burning retorts and other fire clay goods, the use of
moveable archways constructed of springer beams and notched slabs arranged in
the manner substantially as herein shewn and described.
Thirdly. In kilns. for burning retorts and other fire clay goods, the use of move-
able arches having springer beams tied together by rods, in combination with
notched slabs in the manner and for the purpose herein described and illustrated in
the drawings.
