Complete Specification Accepted, 7th Aug., 1888
1, GILBERT SAMUEL TUNKS of 2 Mill Lane, Cardiff, in the county of Glamorgan,
engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction and shape of the crowns or roofs of
"decker" ovens for baking bread biscuits and the like.
Instead of constructing the crowns, as hitherto, of flat metal plates or slabs of fire
clay supported on girders situated at intervals between the side walls, they are, under
this invention, composed of one or more metal sheets or plates extended from one wall
to the other in the form of an arch or a series of arches the ends of which are bedded
in or rest on the side walls. The sheets or plates constituting the arched crown may
be either corrugated or plain.
The use of girders for supporting the crown or crowns, as aforesaid, is dispensed
with and when there are two or more "decks" in the oven, they are capable of being
arranged at a less height above one another than heretofore.
llence such ovens are rendered more compact and easier to manage, the decks
being brought within more convenient reach. Leakage of steam from bread in
process of baking is prevented or lessened, and the cost of construction of the ovens is
reduced.

page_text: I, GILBERT SAMUEL TUNKS of 2 Mill Lane, Cardiff, in the county of Glamorgan,
engineer, do hereby declare the nature of this invention and in what manner the saine
is to be performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to the construction and shape of the crowns or roofs of
decker ovens for baking bread, biscuits and the like.
Instead of constructing the crowns, as hitherto, of flat metal plates or slabs of fire
clay supported on girders situated at intervals hetween the side walls, they are, under
this invention, composed of one or more metal sheets or plates extended from one
wall to the other in the form of an arch or a series of arches the ends of which are
bedded in or rest on the side walls. The sheets or plates constituting the arched
crown may be either corrugated or plain.
The use of girders for supporting the crown or crowns, as aforesaid, is dispensed
with and when there are two or more "decks" in the oven, they are capable of being
arranged at a less height above one another than heretofore.
Hence such ovens are rendered more compact and easier to-manage, the decks
being brought within more convenient reach. Leakage of steam from bread in
process of baking is prevented or lessened, and the cost of construction of the ovens
is reduced.
The accompanying drawing represents a vertical section of a bakers' three-decker
oven constructed and arranged in accordance with this invention.

The crowns a above each deck" consist of plates of steel or iron either plain or
corrugated. The plates extend from one side wall b of the structure to the other in
the form of an arch or a series of arches the ends of which are bedded in or rest on
the walls.
These roofs or arches take the place of the flat slabs of fire clay heretofore com-
posing the crown and supported by girders. The girders are dispensed with and the
decks are brought nearer to each other and hence the oven, as a whole, is more compact,
rendered easier to work and is made more convenient generally.
The flues c and the floors d are arranged and constructed as is usual in such ovens.
Having now particularly described and ascertained the nature of this invention, and
in what manner the same is to be performed, I declare that what I claim is :-
:-
In a decker oven, constructing the roofs or crowns over the decks of plates of steel
or iron, either corrugated or not, such plates being in the form of an arch or a series
of arches extending across the oven, substantially as described and shown in the
accompanying drawing.
