Improvements in and relating to Tins for Baking Bread.
I, ERNST BERGER, of II Treustrasse 18, Vienna, in the Empire of Austria,
Military Superintendent, do hereby declare the nature of this invention to be as
follows:-
My invention relates to tins for baking bread.
The tins constructed according to my said invention comprise a number of
frames, by means of which pieces of dough may be baked in loaves of bread of
uniform shape, such as are suitable for supplying regiments of soldiers on the
march or seamen on board ship. These frames corresponding in size to the size of
the pieces of dough are supported upon a bed plate and adapted to be closed
by a single cover. In the said frames the pieces of dough are first allowed to
ferment and then, baked. The cover prevents the swelling of the expanding dough
beyond the edges of the frames so that precisely uniform pieces of bread are
obtained which will be especially suitable for packing and transport.
The cover may be fixed in various manners to the bed plate carrying the said
frames. In an arrangement which has been found advantageous the bed plate
possesses four upright lugs provided with apertures through which four rods guided
in low-pieces on the cover are slid for the purpose of securely locking the latter.
The closing and opening of the cover is effected by turning a handle on a bolt
attached to a disc which is held between the cover and a bow piece firmly secured
upon the latter. In its turning movement the disc carries away the four rods which
are pivoted to it. When therefore the disc is turned by means of the handle in one
direction the four rods are drawn from the apertures in the lugs on the bed plate,
whereupon the cover can be removed. By a turning movement of the handle in
the opposite direction the four rods are caused to pass into the apertures and lock
the cover.
In order that this turning movement shall not be excessive, as it would
permit the rods to be drawn again from the apertures, I arrange on the cover a stop
pin against which one of the rods will bear in the locking position, thereby
preventing a further turning movement of the disc.
As the inner ends of the aforesaid rods slide partially below the disc when the
cover is unlocked they are provided with recesses to permit this movement, and to
form upper sliding surfaces for the above mentioned purpose.
Instead of several frames I may arrange on the bed plate one large frame divided
into compartments, each of which may be charged with a piece of dough.

Improvements in and relating to Tins for Baking Bread.
1, ERNST BERGER, of II Treustrasse 18, Vienna, in the Empire of Austria,
Military Superintendent, 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:—
.

page_text: The tins constructed according to my said invention comprise a number of frames
by means of which pieces of dough may be baked to obtain loaves of bread
of uniform shape such as are suitable for supplying regiments of soldiers on the
march or seamen on board ship. These frames corresponding in size to the size of
the pieces of dough, are supported upon a bed plate or tray and adapted to be
closed by a single cover. In the said frames or moulds the pieces of dough are
first allowed to ferment and are then baked, the cover prevents the swelling
of the expanding dough beyond the edge of the frames, so that precisely uniform
pieces of bread are obtained which will be especially suitable for packing and
transport.
In the accompanying drawing,
Figure 1 shows a vertical central section, and
Figure 2 a plan of a closed tin arranged according to the said invention.
Figure 3 is a perspective view of the same with the cover removed, and
Figure 4 shows a frame designed for the reception of a piece of dough.
As shown, the improved tin comprises a bed plate or tray 6 which is adapted to
receive a number of frames or moulds a (6 being shown in the drawing) charged
with pieces of dough, and a cover c which extends over all the frames or moulds and
can be secured thereto.
The cover c may be fixed in various manners to the bed plate or tray carrying
the said frames or moulds. In an arrangement which has been found advantageous,
and which is represented in the accompanying drawing, the said tray & is provided
with four upright lugs having apertures & through which rods e passing through
eyes c¹ on the cover c are slid for the purpose of securely locking the cover to the
moulds. The opening and closing of the cover c is effected by turning a bolt d by
means of a handle d' whereby a disc d' is caused to turn. This disc is held between
the cover c and a bridge piece d' firmly secured upon the latter.
In its turning movement the disc moves away the inner ends of the four rods c³
which are pivoted to it. When therefore the disc dis turned by means of the
handle d in the direction of the arrow (Figure 2), the four rods are drawn from
the apertures in the lugs on the bed plate or tray b whereupon the cover c can be
removed. By a turning movement of the handle d' in the opposite direction the
rods are caused to pass into the apertures 6 and lock the cover to the moulds.
In order that this turning movement shall not be excessive, as it would permit
the rods to be withdrawn again from the apertures 62 I arrange on the cover ca
stop pin against which one of the rods will bear in the locking position thereby
preventing a further turning movement of the disc d'.
As the inner ends of the aforesaid rods slide partially below the disc d'
when the cover is unlocked they are, as shown in Figures 3 and 4, provided with
recesses to permit this movement, and to form upper sliding surfaces for the above
mentioned purpose.
Instead of several frames or moulds a I may arrange on the bed plate or tray b
one large frame or mould divided by partitions into compartments, each of which
may be charged with a piece of dough.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is :-
First. A tin for baking bread in uniform loaves, consisting of a bed plate or
tray which is designed for the reception of a number of frames or moulds a con-
taining the single portions of dough or of a single frame or tray comprising a
number of moulds, and a cover c extending over all the frames or moulds and
removably fixed to the bed plate or tray b.
Second. A baking tin of the kind above described, having a bed plate or tray b
provided on each side with lugs b', each lug having an aperture 62, the cover plate c
being provided with rods adapted to be displaced horizontally and having their

page_text: inner ends jointed to a disc d' which can be turned, so that in the turning movement
of this disc d' the outer ends of the rods & enter the apertures 6 in the lugs b³ of the
bed plate or tray or are drawn from these apertures.
