I WILHELM STEIN of 54 High Street, Whitechapel in the county of Middlesex,
Baker do hereby declare the nature of my said invention for "IMPROVEMENTS IN
BAKERS' OVENS to be as follows:- .
"
This invention relates to improvements in bakers' ovens the object of the inven-
tion being to so construct the oven that the floor thereof is entirely separated from
the furnaces whereby the products of combustion can pass out into the chimney
without coming in contact with the goods in the oven; the baking operations can
be carried on continuously and the furnaces after having been once fired so as
to heat the oven to a certain temperature will not require further attention for
a considerable space of time.
In carrying out my invention I construct the oven with two furnaces situated
at the front thereof instead of with one furnace placed at the back as has hitherto
been the practice; the said furnaces are connected by a flue extending under the
floor of the oven which is placed on the incline and is entirely enclosed; from the
said flue extend a number of flues running under the floor of the oven and towards
the back thereof and returning over the crown, whence they enter a flue leading
to the chimney; on one side of the front of the oven I provide a gas jet so placed
as to light the floor of the oven and on the opposite side is a steam pipe extending
into the floor of the oven to allow of baking with steam when required; a suitable
gauge is provided for indicating the heat of the oven; over the crown of the oven is
a self supplying boiler for the purpose of supplying the bakehouse with hot water.
I heat the oven by means of coke whereby a great economy is effected and the
oven is thereby rendered smokeless.

Baker, do hereby declare the nature of my said invention for "IMPROVEMENTS IN
BAKERS OVENS" 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 improvements in bakers' ovens, the object of the
invention being to so construct the oven that the floor thereof is entirely separated
from the furnaces, whereby the products of combustion can pass out into the
chimney without coming in contact with the goods in the oven; the baking
operation can be carried on continuously and with cleanliness and the furnaces,
after having been once fired, so as to heat the oven to a certain temperature,
will not require further attention for a considerable space of time I also avoid
the nuisance of smoke.
In carrying out my invention I construct the oven with two furnaces situated
at the front of the oven and flush therewith instead-of-with-one-furnace placed at
the back, or at-an-angle as has hitherto been the practice; the said furnaces are
connected by a flue extending under the floor of the oven, which can be placed
on the incline or horizontally according to requirements and is entirely enclosed';
from the said flue extend a number of flues running under the floor of the oven
and towards the back thereof where they open into flues returning over the crown
and entering a flue leading to the chimney; on one side of the front of the oven
I provide a gas jet so placed as to light the floor of the oven, and on the opposite
side is a steam pipe extending into the floor of the oven, to allow of baking with
steam when required; a suitable gauge is provided for indicating the heat of the
oven; over the crown of the oven is a self supplying boiler, for the purpose of
supplying the bakehouse with hot water.
I heat the oven by means of coke, or anthracite coal whereby a great economy
is effected and the furnaces are thereby rendered smokeless.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing, in which figure 1 represents a
front elevation of a baker's oven, constructed according to my invention; figure 2
represents a sectional plan on line A, B, of figure 1., Figure 3 represents a vertical
longitudinal section on line C, D, of figure 1, and figure 4, represents a sectional
plan on line E, F, of figure 1. Similar letters of reference in all the figures represent
similar parts.
a represents the oven properly so called or chamber in which the baking opera-
tion takes place, which chamber is shewn horizontal and is entirely enclosed;
(I sometimes however prefer to arrange the floor of the oven on the incline).;
b and c are the two furnaces situated underneath and at the front of the oven;
d, is the flue connecting the furnaces b, and.c, the said flue, extending underneath
the floor of the oven an as shewn in figure 3, and in dotted lines in figure 2;
e, e, e, are the flues which extend from the flue d, and run under the floor of the
oven a, towards the back thereof, where they open into two vertical flues f, and g,
(figure 2) which return over the crown of the oven a, as shewn in figure 3, to the
front thereof; h, and i, are dampers placed at the front ends of the flues f, and g,
respectively for the purpose of regulating the draught in the said flues.

page_text: The flues f, and g, then open upwards and are continued round the sides of the
top of the oven, as shewn in figure 4, one of the said flues g, being also carried
round the back where it joins the other flue f, at b¹, which represents the flue
leading to the chimney not shewn in the drawing.
In figure 1 I have shewn the door a', of the oven which may be of any suitable
construction. At the top of the said door is placed a grating a³, which is connected
with the flue f, by a flue, shewn in dotted lines at a³, in which is placed a damper a*.
The grating a (the damper a being opened) serves, when the door a³, is opened,
to allow of any steam or the like which may issue from the oven a, to pass through
the flue a³, into the flue f, and thence to the chimney; j figure 2, is the gas jet
serving to light the floor of the oven a, the said gas jet being placed in a passage k,
which leads from the exterior to the interior of the oven a, where it terminates in
a lens or bulls-eye l, through which the light is distributed over the floor of the
oven; m, is the steam pipe on the side of the oven opposite the passage k, and
extending into the floor of the oven a, as shewn in figure 2, the said steam pipe
serving to allow of baking with steam when required; n, figure 1, is the gauge for
the purpose of indicating the heat of the interior of the oven a, the said gauge
being connected with the same by a pipe o; p, is the self supplying boiler placed
at the top of the oven as shewn in figures 1, 3, and 4, for the purpose of supplying.
the bake-house with hot water.
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. Constructing-baker's-ovens with the chamber in which the baking operation
is carried on entirely-enclosed and separated from-the-furnace or furnaces sub-
stantially-as and for the purposes hereinbefore described and represented in the
accompanying drawing.
2. 1. In a baker's oven the combination of an enclosed baking chamber with two
furnaces separated therefrom and situated at the front of the oven, substantially as
herein before described and represented in the accompanying drawing.
3. 2. The general arrangement and construction of the improved baker's oven
substantially as hereinbefore described and represented in the accompanying
drawing.
