Improvements in Heating Chambers or Closets.
I, CHARLES APPLEBY of Cannon Street, in the City of London, Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to chambers or closets in which it is desired to preserve a
uniform and even temperature, for the purpose of melting and keeping melted tallow
or other ingredients used in the manufacture of candles, refining oils such as mineral
oils and scale from shales, cooking, and other purposes.
The improved hot chamber or closet consists of a rectangular vertical chamber, of
metal, wood, or other suitable material or materials, the front being open and provided
with hinged or other doors preferably of metal. The two vertical sides have a series
of ledges or ribs, inclined slightly from the front toward the back of the chamber, or
from the back toward the front, each opposite pair forming supports to carry hollow
loose partitions the ends of which rest upon them. These hollow partitions are
preferably of iron or other metal, consisting of a top and bottom plate of suitable size
and thickness rivetted at their edges to a frame of corresponding size. These several
hollow partitions are arranged one above the other, at a convenient distance apart,
upon the ledges or ribs, and to the upper one preferably at or near the corner of one
end is connected a pipe by which steam of any desired temperature can be introduced
from a boiler or other source of supply. From the opposite corner of the other end
a pipe is connected to the hollow partition next below, from the opposite corner of the
other end of which a similar pipe communicates with the next lower partition, and
so on to the lowest partition from which a pipe is led away to any suitable place
where the steam is discharged.
The lower part of the chamber may be provided with a bottom below the lowest
partition and a short distance from the floor and the space below such bottom may be
left hollow or may be filled up.
Cocks or valves may be arranged by which the supply of steam is regulated, and
instead of the arrangement described, the steam may be admitted into all the parti-
tions through separate pipes.

page_text: The several pipes are provided with couplings by which they can be readily con-
nected or disconnected.
Steam in suitable quantity may,
in some cases, be admitted into the chamber as well
as into the hollow partitions, and the latter may be strengthened by stays between the
top and bottom plates if necessary.
The chamber or closet may be surrounded with any suitable non-conducting
material if desired.
The substances to be melted, kept hot, or cooked, are placed in suitable receptacles
upon the hot partition, or upon the latter direct, and the desired temperature is readily
and easily kept up as long as may be desired. Gutters, or channels or pipes, may be
arranged at the lower sides of the partitions into which any melted tallow or other
inaterial is received and conveyed away.
The form and arrangement of the apparatus may be varied more or less according
to the purpose and conditions under which it is to be used.

Improvements in Heating Chambers or Closets.
I, CHARLES APPLEBY, of Cannon Street, in the City of London, 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 state-
ment and accompanying drawing, (that is to say)
This invention relates to chambers or closets in which it is desired to preserve a
uniform and even temperature, for the purpose of melting and keeping melted tallow
or other ingredients used in the manufacture of candles, refining oils such as mineral
oils and scale from shales, cooking, or other purposes.
The improved hot chamber or closet which forms the subject of my present inven-
tion consists of a vertical chamber preferably rectangular, of metal, wood, or other
suitable material or materials, the front being open and provided with hinged or other
doors preferably of metal. The two vertical sides have a series of ledges brackets, or
ribs, which may be made if desired inclined slightly from the front toward the back
of the chamber, or from the back toward the front, each opposite pair forming
supports to carry hollow loose partitions the ends of which rest upon them. These
hollow partitions may be made in any convenient way, but preferably of iron or other
metal, consisting of a top and bottom plate of suitable size and thickness rivetted at
their edges to a frame of corresponding size.
The several hollow partitions are arranged one above the other, at a convenient.
distance apart, upon the ledges, brackets, or ribs, and to the upper one preferably at
or near the corner or centre of one end is connected a pipe by which steam of any
desired temperature can be introduced from a boiler or other source of supply.
From the opposite end, preferably near one corner, a pipe is connected to the hollow
partition next below, from the opposite corner of the other end of which a similar
pipe communicates with the next lower partition, and so on to the lowest partition
from which a pipe is led away to any suitable place where the steam can be conveniently
discharged.
The lower part of the chamber may be provided with a bottom below the lowest
partition and a short distance from the floor, and the space below such bottom may be
left hollow or may be filled up.
Cocks or valves may be arranged by which the supply of steam is regulated.
Instead of the arrangement described, the steam may be admitted into all the
partitions through separate pipes. The several pipes are provided with couplings by
which they can be readily connected or disconnected.
In the accompanying drawing, which is in illustration of the invention, figure 1 is
a front view partly in section of a heating chamber constructed in the manner last
described. Figure 2 is a transverse vertical section and figure 3 a horizontal section
of the sainc. a is the back of the chamber, of wood or other suitable material,
having a top a', and its open front being fitted with metal doors b, b, turning upon
hinges c, c'. The two metal sides d, d', are provided with brackets e, e, e, upon which

page_text: rest the hollow loose partitions f, f. f, consisting of top and bottom plates, g, g';
rivetted at their edges to a frame (as shewn on a larger scale in figure 4). To one
end of the several partitions fare connected steam pipes i, i, i, which pass out through
the side d of the chamber and are connected to the steam supply pipe k, provided with
a regulating valve 1. From the opposite end of the several partitions
pipes, are shewn connected with the discharge pipe m, also provided with a
valve n.
similar
Couplings are arranged at o, o, o, by which the pipes can be readily connected or
disconnected.
Steam in suitable quantity may, in some cases, he admitted into the chamber as well
as into the hollow partitions, and the latter may be strengthened by stays between the
top and bottom plates if necessary; as indicated at p, p, p, in figure 3.
The chamber or closet may be surrounded with any suitable non-conducting material
if desired.
The substances to be melted, kept hot, or cooked, are placed in suitable receptacles
upon the hot partition for upon the latter direct, and the desired temperature is
readily and easily kept up as long as may be desired. Gutters, or channels or pipes,
(not shewn in the drawing), may be arranged at the lower sides of the partitions
into which any melted tallow or other material is received and conveyed away.
The form and arrangement of the apparatus may be varied more or less according
to the purpose and conditions under which it is to be used.
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 :-
:-
1. The heating apparatus, consisting of the chamber open at the front and provided
with doors b, ', and brackets, ledges, or ribs e, upon which rest the hollow partitions,
into which steain can be admitted as desired through the supply pipe & and connecting
pipes, and conveyed away, after passing through the partitions, through the
discharge pipe m, and connecting pipes, substantially as and for the purposes
described and shewn.
2. In combination with the moveable partitions, supply pipe k, discharge pipe m,
and connecting pipes i, , the couplings o, substantially as and for the purpose
described and shewn.
