An Improved Transportable Bakery.
I, LEON DATHIS, Junior, of 33 Aronne de l'Opara, Paris, in the Republic
of France, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed to ho particularly described and ascertained
in and by the following statement :-
-
The purpose of this invention is to provide a vehicle whether a railway or a
road vehicle or a ships' cabin with a collection of all the necessary apparatus
connected with the making of bread, in as convenient and compact a mannor as
possible ready for use so that the same may form a transportable bakery usable
at any time and whether at rest or while the vehicle or equivalent housing, in which
it is installed is being moved from place to place.
The apparatus is thus useful for military or other purposes, since it may be used
in any location until such time as it is wanted to be transferred onto wheels or
onto ship-board and thus can be always kept in proper and complete working
order.
The invention is illustrated in the annexed drawing as applied to a railway
vehicle, Fig. 1 being a vertical section, Fig. 2 a plan or horizontal section.
The apparatus comprises an oven A with arrangements for concentration and
distribution of the heat, a smoke consuming or equivalent furnace or stove, a
thermometer, a thermosyphon, that is to say, a water circulating pipe intended to
be heated by the heat in the walls of the oven or otherwise radiating therefrom, a
movable grate or bottom for charging the oven and a bell cover with means for raising
and lowering the lattor. A table B for the charging of the oven or use in this operation
is also provided, same being provided with arrangements permitting of its being
revolved or tilted. A vessel C for aerating the dough is comprised in the apparatus,
this vessel having a double bottom or wall C¹ for circulation of steam or hot water for
heating the dough and maintaining it at the temperature desired, and trays or
basins D are provided for receiving and serving at the same time as measures for
the dough for fermentation, there being placed over each mass of dough an
automatic alarm, consisting of a slide, provided with two parallel bars as a piston,
which are lifted up to that height to be reached by the dough when completely
developed. When the dough has reached this degree it lifts the piston, which latter
by the aid of its parallel bars or rods actuates an electric contact in connection with
a bell, giving a sign that the dough is ready.
Above these trays or receivors is a shelf or table L for fashioning the loaves. A
removable water tank with a filter E serves as a feeding reservoir for the water
used in the various operations. Measures F with supply and draw off pipos F'
are provided for the accurate supply of liquid for the dough, and shelves II forming
compartments with doors for storing the loaves before baking and racks J for
the baked loaves. The vehicle is fitted with a ventilator I to the aforesaid shelves
and the water tank E supplies also the thermo-syphon G of which the purpose is
to heat and supply water to the oven for condensation on the bread and to the
dough aerator.
The apparatus referred to as a thermosyphon comprises the tank or
which is supplied with water from the tank E by means of the pipe G.
vessel G'a pipe G³ passes down about the fire box, under the oven and
vessel as shown in Fig. 1 at a higher level. This device forms' a
vessel G¹
From the
back to the
hot water

page_text: circulating system by which the water in the vessel G' is honted without particular
expense by the furnace of the oven A. The vessel G' provides the hot water with
which it is advisable to charge the oven to provide a damp atmosphere for the
baking, this water being drawn off as desired by the attendant and preferably at
each charging of the oven, through the pipe Ġʻ provided with cock G. The
water flows into the interior of the oven into an aunular channel of thick channel
iron such as G, Fig. 2, which being hot vaporizes the wator almost instantly so as
to provide moisture to condense upon the bread. This thermosyphon or hot water
circulating system may also provide water for a storage tank below tho fire grate
and ash pan and a pipe G also lends therefrom for the supply of hot water to the
tank S whence hot water is drawn, when desired for preparation of the dough, into
the double bottom or jacket C of the vessel C, this water entering the said double
bottom or jacket through the hollow contral axle pin of tho said vessel. The
feeding of hot water to this double bottom and the removal of the water after it
has become cool are effected both by this same passage way namely the hollow axle
pin, the communicating pipe thereto being provided with a double way cock R so
that communication may be effected between the double bottom and tank S or
between the double bottom and a waste pipe loading to said two way cook.
The oven is charged by placing the unbaked loaves, removed from the shelves H,
on the removable platform A', the latter having been swung out over the table B,
by the swinging frame B', the grato with the unbaked loaves is then swung back
into the oven by but one push, and taken out in the same way, when the baking is
done. K is the coal bin for feeding the furnace of the oven A. U represents flour,
necessary for bread making, stored in sacks.
During the travelling of the bakery-waggon the kneading trough C and the
ventilator I aro nctuated by the axles M of said waggon, which communicato
movement to two intermediate shafts N and N provided with pulleys M' and two
differential cones O and O', which are actuated from inside of the waggon by the
movement of a crank T, the latter permitting the velocity to be regulated. When
the waggon is at rest the pulley M' of the arbor N and all the movements
originating from said pulley may be started by any appropriate motor, such for
instance as a gasoline motor, placed in the waggon or on the ground, or in any other
way, if it is not desired to operate the apparatus C and 1 by hand.
By these means a bakery transportable at any time is obtained, provided with all
necessary utensils and appliances ready for use. It is likewise easy, if preferred, to
arrange this apparatus in a movable house or chamber, which can be placed
together with its contents upon a platform waggon, a ship or any vehicle if it is
wanted to be moved from place to place. This last mentioned combination offers
the additional advantage that it permits of separate use of the vehicle, be it a
covered waggon or a platform or a ship etc., for the service to which it is ordinarily
destined, also to use the apparatus for the ordinary bread making in any place in
which they may be situated in the movable cases in which it is housed or otherwise,
while in case of need it is sufficient to combine in a few hours all these elements, to
make them transportable and to form one whole as described, without great
expense being needed, the apparatus in such case not deteriorating for want
of use.
Having now particularly described and ascertained the naturo of the said inven-
tion and in what manner the samo is to be performed, I declare that what I
claim is :-
1. A new transportable bakery as described hereinbefore and represented as in
instance in the annexed drawing, having its encasing housing fixed or removable as
a whole as well as in detail for the purpose set forth.
2. The combination of a series of baking appliances, of any system, with a vehicle,
such as a waggon, ship, carriage or the like, and a movable case or housing for
Baid appliances or the vehicle itself forming the housing; this combination serving

page_text: to render the bakery apparatus transportable at will, and usable when travelling,
substantially as set forth.
