PROVISIONAL SPECIFICATION.
Improvements in Cooking Ranges.
ALFRED THOMAS HEBRON Marble Merchant 2 Wilfred Terrace Whitley
Northumberland do hereby declare the nature of this invention to be as
follows:-
"
My invention relates to the class of cooking range known as the "Glendinning
or "hot air range" the oven of which is placed at a higher level than the fire and
usually made of sheet iron or similar material and is heated with hot air from the
adjoining fire, the flames being killed by taking the flue a circuitous course before
reaching the oven. As made at present it takes an expert to build in an oven
successfully.
*The principal object of my invention is, by encasing the oven with walls of metal
fire clay or other material (Fig. 1) or metal lined with fireclay or other heat
retaining material (Fig. 2) and leaving a space between the two sides, back, top, and
bottom, to form the flues (B Fig. 1) thus ensuring an equal distribution of the hot
air to each side or flue of the oven and by this means enable any ordinary bricklayer
or mason to set it with a certanty of it answering, and if required by making
it accessible from the front (Fig. 3) the oven, flues, or any portion can be cleaned
repaired or replaced without the usual trouble and expense of taking down the
range; furthermore the fireclay or other heat retaining lining which may be used
against the outer casing or walls & inside the flues (Fig. 2) will retain the
heat & prevent the oven cooling too rapidly and regulate the temperature with a
greater degree of certanty.
Fig. 1 shows side section of oven & flues-A is oven, B flues surrounding oven,
C iron legs placed at each bottom corner of oven to support it at back, D is metal
plate extending the whole length and breadth of back flue to prevent the hot air
passing too quickly away. It may also be made by placing strips of metal down the
sides thus forming a hot air chamber which if required may have a small hole
or holes at top to clear itself. E shows opening to admit hot air. F is outlet for
flue which is usually fitted with damper. G is front plate.

Fig. 3 shows front of oven when fixed I being a portion of front which it is
intended to fix onto the oven and can be removed with oven when access to back of
oven or flues is required. The oven front may be removed in various ways to gain
access to the flues, as shown in Fig. 3 is the method intended at present to
work it.

COMPLETE SPECIFICATION.
Improvements in Cooking Ranges.
I, ALFRED THOMAS HEBRON, of 2 Wilfred Terrace, Whitley, in the County of
Northumberland, Marble Merchant, 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 :--
3: My invention relates to that class of cooking range known as the "Glendining"
of hot air range, the oven of which is placed at a higher level than the fire.

In ranges of this description, the flames are taken a circuitous course through a
flue to the base of the oven, which is heated by the products of combustion, the
said flames having been "killed" by their passage through the flue. As constructed
at present it requires an experienced workman to build a range of this description,
and when built the said range is very inaccessible for repairs.
In order that my invention may be clearly understood, I will proceed to describe
same with reference to the accompanying drawings in which similar letters refer to
like parts in all the figures."
Figure 1 is a front elevation of a range constructed according to my invention.
Figure 2 is an end elevation of same, partly in section.
Figures 3, 4, 5, 6 and 7 are detail views.
-1
According to my invention I employ a casing A, which may suitably be made of
sheet metal, such casing being attached in position in the fireplace in any suitable
way. To this casing AI attach a front plate B by means of the screws C, which
.latter enable the same to be taken apart from the main structure when desired.
The front plate B may be removably attached to the casing A in one piece as
shown in the drawings, er it may be divided into sections or parts, each section or
part being attached separately, as may be found most convenient.
Within the casing A 1 place the oven D in such a manner as to leave a space all
round same, thus forming the flues E.. A front plate F is attached to or forms part
of the oven D, and holes F' Fig. 4 are formed in the said plate whereby the oven
is fixed to the front plate B by passing the screws G through the front plate F and
into the lugs H of the said front plate B. By this means the oven D is firmly fixed
in position within the casing A, whilst at the same time it may be readily detached
from the front plate B..
The plate F may be extended upwards in order to take in the damper rod D' and
.cleaner_rods D2 as shown at Figs. 6 and 7, so that on removing the oven with its
plate F from the front plate B, the said damper and cleaner are removed
simultaneously therewith.
To the oven D is attached a plate J, which may extend across the whole of the
back flue E, thus preventing the hot air passing away too quickly; or strips
of metal may be placed down the sides, thus forming a hot air chamber, which may
.have a small hole or holes in the plate J to clear itself.
:
In order to adjust the height of the back portion of the oven D, I employ the
adjusting legs or supports K at each bottom corner, such legs K consisting of
a screw and nut arrangement; and in the front 'plate B is a hand hole L, so that
the man fixing the said oven D can, by putting his hand through the hole L, adjust
the height of the oven back after it is placed in position.
The casing A. is preferably lined with fireclay or other heat retaining material M,
thus retaining the heat to the oven D and making it act better, at the same time
preventing such oven D cooling too rapidly; but where cost is a consideration, this
lining M may be dispensed with.
The hole N through which the hot air from the fire passes to the oven D, is made
by two pieces N' and N2, the piece N' fitting into the piece N2, whereby the central
piece N¹ can be lifted out when required to clean or repair the flue. P is the
outlet to main flue, which is usually fitted with a damper P¹.
'
It will be readily seen that by employing the above described arrangement of
detachable front plate B either in sections or in one piece, and also by having the
oven D detachable, the parts can be readily and quickly removed, and access from
the front of range to the flues and other parts, can be obtained without in any way
interfering with the casing A, and thus such flues or any other portion can be
cleaned, repaired or replaced without the usual trouble and expense of taking down
the whole range.
It will also be obvious that by constructing the range as above
described; any ordinary bricklayer can "set" the same, thus obviating the necessity
of employing an expert to build the oven successfully...
"At Figure 5 I have shown a suitable arrangement; for forming the connection
between the plate F and the front,plate B, but it will be readily understood that

page_text: any other suitable means may be employed without departing from the nature of
my invention.
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 :-
1. A metal or other casing permanently inserted in the fireplace, in combination
with a removable front plate substantially as and for the purposes set forth.
2. The combination of the front plate B, plate F, and oven D, substantially as
and for the purposes set forth.
3. The combination of the front plate B, plate F, oven D, legs K, plate N³, and
casing A, substantially as and for the purposes set forth.
4. The combination of casing A, front plate B, screws C, oven D, flues E, plate F,
screws G, lugs H, plate J, legs or supports K, hand hole L, lining M, pieces Ni
and Ns, outlet P, and damper P', substantially as and for the purposes set forth.
5. The general arrangement, construction, and combination of the various parts
forming the cooking range substantially as and for the purposes set forth.
