Year: 1884

page_text: I FRANKLIN HOOKING of 16 Spellow Lane, Liverpool in the County of Lancaster,
Engineer do hereby declare the nature of the said Invention for IMPROVEMENTS IN
OVENS, OR STOVES FOR COOKING AND OTHER PURPOSES, to be as follows:-
My Invention relates to certain improvements in ovens, or stoves and more
particularly to that class of ovens, or stoves in which the heating agent is that
of gas, and has for its object the application of gas, or other heating medium, as
a heating agent for ovens and stoves in such a manner that an efficient beating
surface with a small consumption of gas, or fuel is provided and so that the
cooking, or other purposes to which the oven, or stove is applied, shall not be
carried on in an atmosphere of the products of combustion of the gas, or other
fuel.
An oven, or stove constructed according to my Invention consists of a casing
around and within the sides of which are provided a series of tapered tubes with
their wide ends at the bottom, or with tubes with contracted outlets, placed side
by side and near together and opening out through the bottom plate of the oven
or stove into a chamber extending under the oven, or stove and opening through
the top plate of the oven, or stove into a chamber extending over the top of the
oven, or stove which chamber is provided with an escape pipe or chimney. Where
gas is the heating agent employed it is supplied through a "Bunsen" or other"
burner, located in a tube, the top of which opens out into the chamber under the
oven, or stove. The bottom plate of the oven, or stove is provided with an inside
guard plate to prevent burning of the articles under treatment in the lower portion
of the oven.
The inside of the oven is provided with racks to carry oven trays in
the usual way, and the oven is provided with a suitable door and air inlet and
outlet valves.
In constructing the oven of double form, the tubes of the oven are carried up to.
and under the top plate to a central chamber which is used for boiling and heating
purposes, such chamber being provided with holes with moveable covers to receive
pans, or other cooking utensils. The oven is also provided with a double row of
tubes in the centre, between which a division plate can be placed These take
up direct from the bottom plate to the chamber above, and Bunsen, or other gas
burners are provided for the bottom chambers of the oven.

page_text: Instead of using gas as the heating agent any hot products of combustion, such
as the hot products from the combustion of coke may be led into the heating
chambers under the botton plates and through the tubes of the oven, or stove.
The use of tapered holes, or tubes with contracted outlets effects the purpose of
checking the too rapid escape of the hot gases passing up and through the tubes.
The construction of an oven, or stove according to my Invention, provides a
large heating surface and affords an economical use of gas and without the
cooking being done in an atmosphere charged with the products of combustion
of the gas.
This Invention is applicable for heating stoves, other than ovens, such as laundry
stoves and airing closets, as it affords a means of heating the stove by gas without
danger of setting the contents on fire.

page_text: I FRANKLIN HOCKING of 16 Spellow Lane, Liverpool in the County of Lancaster,
Engineer do hereby declare the nature of the said Invention for IMPROVEMENTS IN
OVENS, OR STOVES FOR COOKING AND OTHER PURPOSES and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :—
My Invention relates to certain improvements in ovens, or stoves and more
particularly to that class of ovens, or stoves in which the heating agent is that of
gas, and has for its object the application of gas or other heating medium, as a
heating agent for ovens and stoves in such a manner that an efficient heating
surface with a small consumption of gas, or fuel is provided and so that the
cooking, or other purposes to. which the oven, or stove is applied shall not be
carried on in an atmosphere of the products of combustion of the gas, or other
fuel.
An oven, or stove constructed according to my Invention, consists of a casing
around and within the sides of which are provided a series of tapered tubes with
their wide ends at the bottom, or with tubes with contracted outlets, placed side
by side and near together and opening out through the bottom plate of the oven,
or stove into a chamber extending under the oven, or stove and opening through
the top plate of the oven, or stove into a chamber, extending over the top of the
oven, or stove, which chamber is provided with an escape pipe, or chimney. Where
gas is the heating agent employed, it is supplied through a "Bunsen or other
burner, located in a tube, the top of which opens out into the chamber under the
oven or stove. The bottom plate of the oven or stove is provided with a guard
plate to prevent burning of the articles under treatment in the lower portion of
The inside of the oven is provided with racks to carry oven trays in the
usual way and the oven is provided with a suitable door and air inlet and outlet

valves.
In constructing the oven of double form the tubes of the oven are carried up to
and under the top plate to a central chamber which is used for boiling and heating
purposes, such chamber being provided with holes with moveable covers to receivo
pans, or other cooking utensils. The oven is also provided with a double row of
tubes in the centre between which a division plate can be placed. These take up
direct from the bottom plate to the chamber above and Bunsen, or other gas
burners are provided for the bottom chambers of the oven.
Instead of using gas as the heating agent any hot products of combustion such
as the hot products from the combustion of coke may be led into the heating
chambers under the bottom plates and through the tubes of the oven, or stove.
The use of tapered tubes, or tubes with contracted outlets effects the purpose of
checking the two rapid escape of the hot gases passing up and through the tubes.
The construction of an oven, or stove according to my Invention provides a
large heating surface and affords an economical use of gas and without the
cooking being done in an atmosphere charged with the products of combustion
of the gas

page_text: This Invention is applicable for heating stoves, other than ovens, such as laundry
stoves and airing closets as it affords a means of heating the stove by gas without
danger of setting the contents on fire.
The beforegoing being the nature object and purposes of my Invention, I will
now proceed to describe more in detail how the same may be carried out into
practical effect reference being had to the accompanying sheet of Drawings and
to the letters and figures of reference marked thereon, like letters and figures
being used to denote the same, or corresponding parts throughout the various

DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation of a tapered tube (shown partly in section) such as I use
in the construction of the oven, or stove.
Figure 2 is an elevation of a tube with contracted outlet such as I use in the
construction of the oven, or stove.
Figure 3 is a sectional plan of an oven, or stove constructed according to my
Invention.
Figure 4 is an elevation taken in section through X X Figure 3.
Figure 5 is a sectional elevation of a double oven constructed according to my
Invention.
Figure 6 is a sectional elevation illustrating the construction of a laundry stove
according to my Invention.
An oven, or stove a constructed according to my Invention consists of a casing A
around and within the sides of which are provided a series of tapered tubes, or
tubes having contracted outlets, B, namely these tubes B are of the form shown
at Figure 1, or of the form shown at Figure 2. In the tapered tube shown at
Figure 1, b is the bottom of the tube and inlet and c is the top of the tubo and
outlet. In the parallel tube shown at Figure 2b is the inlet. c is the outlet, the
outlet c being contracted in manner such as shown. In the construction of the oven
the tubes B are arranged within and around the sides and back of the casing A as
shown at Figures 3 and 4. The inlet of the tubos B opening out through the
bottom plate D of the oven and the outlet c of the tubes B opening out through
the top plate E of the oven and into a chamber F extending over the top of the
oven, which chamber is provided with an escape pipe, or chimney H. Where gas
is the heating agent employed, it is supplied through a Bunsen, or other burner J,
located in a tube K the top of which opens out into a chamber L extending under
the bottom of the oven as shown. M is a guard plate which is fitted under the
centre of the plate D forming the bottom of the oven. The inside of the oven
namely the space contained by the tubes B is provided with racks to carry oven
trays in the usual way, but not shown in the Drawings. The oven is provided
with a door N fitted with the usual air inlet and outlet valves, and the gas burner J
is provided with the usual supply pipe and cock P.
Although I have shown the oven in Figures 3 and 4 provided with the parallel
'form of tube with a contracted outlet as shown at Figure 2, I would have it under-
stood that the tapered form of tube shown at Figure 1 may be substituted, being
fitted in the same way within the casing A between the plates D and E.
In the example illustrated at Figure 5 I have shown a double oven. In this
case, the outside tubes B are bent at B¹ and come under the top of the oven, and
open into the chamber F which is in the centre of the oven. These tubes are of
parallel construction with contracted outlets. There are also provided a double
row of tapered tubes B in the centre and between which a division plate A¹ is
placed. These tubes B take up direct from the bottom plate D to the underside
of the chamber F. J J are Bunsen burners which are provided in manner similar
as described in reference to Figures 3 and 4. The top of the chamber F may be
provided with holes F' with moveable covers to receive pans and other cooking
utensils A chimney H is also provided and the oven is fitted with suitable doors,>

page_text: The application of my Invention to heating stoves for laundry and like purposes
is shown at Figure 6. The sides of the stove are provided with a system of tubes B
and a gas burner J is provided, with flame nozzles, or jets coming under the inlet b
of each tube B. The tubes are fitted between the plates D and E and have their
outlets into the chamber F. Air inlets a are provided in the casing A and outlets a¹
are provided in the plate E, so that the vapour from the stove will pass off into the
chamber F. The interior of the stove may be fitted with bars for hanging clothes,
or other purposes,
As before stated any hot products of combustion may be led into the chambers L
in substitution of the gas burners J. but the essential feature of my Invention is
the use of the tapered tubes, or tubes having contracted outlets whereby the too
rapid escape of the hot gases passing up through the tubes b is checked.
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
First The combination with ovens, or stoves of the type herein described of
tubes through which the heated products of combustion of gas, coal, or coke are
passed as set forth.
Second In ovens, or stoves of the type herein described in which tubes are
employed, constructing such tubes with contracted, or choked outlets, or of tapered
form, as set forth for the purposes specified.
Third The construction of oven and arrangement of tubes as set forth with
reference to Figures 3 and 4 of the Drawings hereto annexed.
Fourth The construction of oven and arrangement of tubes as set forth with
reference to Figure 5 of the Drawings hereto annexed.
