We CHARLES HENRY HARDING of 23 Humberstone Gate Leicester Baker and
Confectioner and ALFRED HUNT of 20 Clarence Street Leicester Builder do hereby
declare the nature of this invention to be as follows:-
This invention relates to that class of ovens commonly called steam ovens in which
hermetically sealed tubes containing only a small quantity of water or other liquid are
employed to convey the heat from the fire--in these ovens difficulty is experienced in
obtaining sufficient top heat without over heating the tubes.
According to this invention in place of carrying the top set of tubes straight
through into the space above the fire as is now usual and having the fire above the
ends of the lower tubes we bend the ends of the top tubes downwards, so that they
come only slightly above the ends of the lower tubes which also are in the space
above the fire the result of this is that a more even heat is obtained and a greater
surface of the top tubes being exposed to the heat their ends do not have to be heated
to such an extent as was before necessary and therefore they are less liable to
burst. Fewer bottom tubes than usual are necessary or a tile bottom can be used
above them.

page_text: Improvements in Bakers' Ovens.
We, CHARLES HENRY HARDING of 23 Humberstone Gate, Leicester, Baker and
Confectioner and ALFRED HUNT of 20 Clarence Street, Leicester, Builder, 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
This invention relates to that class of ovens commonly called steam ovens in which
hermetically sealed tubes containing only a small quantity of water or other liquid are
employed to convey the heat from the fire-in these ovens difficulty is experienced
in obtaining sufficient top heat without over heating the tubes.
According to this invention in place of carrying the top set of tubes straight
through into the space above the fire as is now usual and having the fire above the
ends of the lower tubes we bend the ends of the top tubes downwards, so that they
come only slightly above the ends of the lower tubes which also are in the space
above the fire the result of this is that a more even heat is obtained and a greater
surface of the top tubes being exposed to the heat their ends do not have to be heated
to such an extent as was before necessary and therefore they are less liable to
burst. Fewer bottom tubes than usual are necessary or a tile bottom can be used
above them.
In order that our said invention may be more fully understood and readily carried
into effect we will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a longitudinal section of an oven constructed according to our
invention.
Figure 2 is a transverse section taken on the line X X, Figure 1.
A A are the top tubes. As is shown in Figure 1 they are bent downwards at the
D D are
furnace end. B B are the bottom tubes Cis the tile sole of the oven.
dampers for regulating the draught. E is the furnace, G is its flue and H a flue to
allow the escape of steam from the inside of the oven.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what we
claim is
1. Our improvement in baker's ovens consisting in curving the ends of the top
tubes downwards so that they come only slightly above the ends of the lower tubes
substantially as described.
2. Our improvement in bakers ovens consisting in exposing a greater surface
of the top tubes than of the bottom 'tubes to the heat substantially as described.
3. Our improvements in bakers ovens substantially as described and shown in the
Drawings.
