PROVISIONAL SPECIFICATION.
An Improved Construction of Ovens for Baking or Roasting.
I, JAMES BLATCH Cox, of Shelton, Torquay, in the County of Devon, Iron-
monger, do hereby declare the nature of this invention to be as follows:-
:―
My invention relates to an improved construction of oven for baking or roasting
in which the heat from the products of combustion of the stove is utilised in a
similar way to that described in the Specification to my previous Patent No. 85 of
1879 and whereby I secure a more uniform distribution of heat and am able to
charge and discharge the ovens with less loss of heat. For this purpose 1 construct
the oven of an outer casing which can either be covered with non conducting
material or such non-conducting material can be enclosed within an outer casing.
Extending from front to back of this casing I arrange a series of chambers side by
side vertically and longitudinally which constitute the ovens proper so arranged that
there is a space left around each, these spaces forming flues through which the hot
products of combustion pass. There are also spaces above the uppermost row of
ovens and below the lowest row. Underneath the lowest space there is a further
space into the centre of which the products of combustion pass from the furnace
stove or other source of heat and being uniformly spread thereover they are con-
ducted by flues preferably tubes arranged at the sides of the ovens to the space
above the uppermost tier of ovens whence it travels downwards through the spaces
between the ovens to an outlet flue in the chamber below the ovens.
In the passages for the hot products of combustion there are suitable baffles so as
to direct them uniformly over the surfaces of the ovens.

COMPLETE SPECIFICATION.
An Improved Construction of Ovens for Baking or Roasting.
I, JAMES BLATCH Cox, of Shelton, Torquay, in the County of Devon, Iron-
monger, 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 :-
My invention relates to an improved construction of ovens for baking or roasting,
in which the heat from the products of combustion is utilised in a manner similar to
that described in my previous Specification No. 85 of 1879. The object of my present
improvements is to secure a more uniform distribution of heat and to facilitate the
charging and discharging of the ovens without loss of heat, as I shall describe
referring to the accompanying drawings.
Fig. is a vertical section of a set of ovens according to my invention, heated
by gas.
Fig. 2 is a similar section shewing the heating by a lateral stove.
Fig. 3 is a similar section shewing a modified arrangement of the flues from the
stove.
In all these figures A is an outer casing made of or lined or covered with material
which is a bad conductor of heat; B indicates ovens extending from front to back
of the chamber enclosed within the casing A, these ovens being arranged with free
passage for products of combustion between them and above and below them.
These ovens are heated, either as shewn in Fig. 1 by a gas burner C of any known
... 0 l

page_text: kind, or as shewn in Figs. 2 and 3 by a stove C. The hot products of combustion
ascend a pipe or flue D directly as shewn in Figs. 1 and 2 to the upper part of the
chamber, or, as shewn in Fig. 3, they first pass under a plate E so as to be spread
out under the floor, and then ascend several pipes D to the upper part of the
chamber.
Thence they descend, circulating around the ovens B, to the lower part of the
chamber and finally escape by a fine E. In order to lessen the draught up the
flue F which might cause the hot gases to pass too rapidly through the chamber, air
from the exterior may be admitted by a small aperture G Fig. 1.
At first starting of the stove, as shewn in Figs. 2 and 3, a valve H is opened
allowing the hot gases to pass directly from the upper part of the chamber to the
flue F. When the flue has become sufficiently heated, the valve H can be closed,.
the hot gases then flowing as indicated by the arrows.
Having thus described and ascertained the nature of this invention, and in what
manner the same is to be performed, I claim :-
A set of ovens for baking or roasting arranged with passages between them and
enclosed within a chamber to the upper part of which hot products of combustion
ascend by a pipe or flue or several of these from a gas burner or stove, and from the
lower part of which the gases, after having passed down over and between the ovens,
are discharged by a pipe or flue, substantially as herein described.
