PROVISIONAL SPECIFICATION.
Improvements in or relating to Refrigerating Apparatus.
I, JULES SCHALLER, of 16, Rue Drouot, Paris, in the Republic of France,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention has for its object a new system of portable refrigerator, which I
have called the refrigerator for castles and the country, because it can work
without making use of ice, which is often difficult to procure far from the centres
of population.
.
It is characterised by the combination, with a double walled recipient, (in which
is plunged the ice pail fixed upon a plate of tinned iron or other metal provided
with orifices permitting of additions being made to the refrigerating substances,
and across which pass the blades of the paddles or agitators fixed in a second plate
of metal or of india-rubber covering the said plate which contains the orifices) of
a system of agitators allowing the agitation of the refrigerating mixture to
accelerate the fusion of the refrigerating salts in the water and to maintain them
all over at the same temperature both in the interior of the mass and against the
walls of the ice pail.
The apparatus consists of two cylindrical or other formed receptacles, made of
any suitable material, but, by preference, of metal, and nested one inside the other.
The interior receptacle is about 16 millimetres narrower than the exterior receptacle,
and the vacant space between the two capacities is filled by a body which is a poor
conductor of heat, such as powdered charcoal, felt, or any other suitable material.
A tap is fixed at the lower middle portion of the recipient to permit the withdrawal
of the refrigerating mixture when the salt is melted, and the adding of salt and
water at the upper part by means of the openings or the like, arranged for the
purpose in the top plate of the apparatus. This mode of construction permits of
adding to, or renewing, the refrigerating mixture without exposing the different
parts of the refrigerator to the action of the exterior air and without manipulations
liable to cause the salt or the water employed to enter into the water, or into the
cream that is required to be congealed, seeing that the ice pail which encloses them
extends about 2 centimetres above the top plate of the apparatus and is itself
furnished with a cover, and also that this ice pail is formed in one piece with the
top plate of the recipient in the lower part of which the mixture is prepared and
contained. In order to agitate the mixture, I make use of a system of beaters
furnished or not with handles, and traversing on the one part the openings in the
top plate, and, on the other part, the openings made in a second plate placed above
the top plate. These openings are themselves covered by covering plates, suitably
arranged in slides, and which move with the rods of the beaters, these latter being
connected at their lower ends by means of a cross piece, thus allowing of the
bottom of the mixture being agitated. The plate at the top of the apparatus is
held by means of a bayonet joint on the external wall of the outer case, and the
latter may, in addition, have an arrangement of handles to enable the apparatus to
be carried about more easily.
It is evident that the forms, dimensions and proportions of the accessory parts
may be varied, and the refrigerators may be formed with several moulds or ice
pails instead of one, and the agitators may be operated from the centre or from

page_text: the side by an arrangement of beaters, moving on a pivot arranged in the centre
of the internal bottom of the vessel, or by any other suitable system of gearing.
Any suitable materials may also be employed for their construction.
The recipient may also be made with a single wall.

COMPLETE SPECIFICATION.
Improvements in or relating to Refrigerating Apparatus.
1, JULES SCHALLER, of 16 Rue Drouot, Paris in the Republic of France
Manufacturer, 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:-
My invention has for its object a new system of portable refrigerator, which I
have called the refrigerator for castles and the country, because it can work
without making use of ice, which is often difficult to procure far from the centres
of population.
It is characterised by the combination with a double walled recipient (in which
is plunged the ice pail fixed upon a plate of tinned iron or other metal provided
with orifices permitting of additions being made to the refrigerating substances,
and across which pass the blades of the paddles or agitators fixed in a second plate
of metal or of indiarubber covering the said plate which contains the orifices) of
a system of agitators allowing the agitation of the refrigerating mixture to
accelerate the fusion of the refrigerating salts in the water and to maintain them
all over at the same temperature both in the interior of the mass and against the
walls of the ice pail.
In order to allow of the invention being more easily understood reference will
now be made to the accompanying drawing on which
Figure 1 is a sectional elevation and
Figure 2 a plan view of my improved system of refrigerator.
The apparatus consists of two cylindrical or other formed receptacles A. B, made
of any suitable material, but, by preference, of metal, and nested one inside the
other. The interior receptacle A is about 16 millimetres narrower than the exterior
receptacle B, and the vacant space between the two capacities is filled by a body
which is a poor conductor of heat, such as powdered charcoal, felt, or any other
suitable material C. A tap D is fixed at the lower middle portion of the recipient
to permit the withdrawal of the refrigerating mixture when the salt is melted, and
the adding of salt and water at the upper part by means of the openings G or the
like, arranged for the purpose in the plate F of the apparatus. This mode of
construction permits of adding to, or renewing, the refrigerating mixture without
exposing the different parts of the refrigerator to the action of the exterior air
and without manipulations liable to cause the salt or the water employed to enter
into the water, or into the cream that is required to be congealed, seeing that the
ice pail E which encloses them extends about 2 centimetres above the top plate F¹
of the apparatus and is itself furnished with a cover E' and also that this ice pail
is formed in one piece with the plate F of the recipient in the lower part of which
the mixture is prepared and contained. In order to agitate the mixture, I make
use of a system of beaters H furnished or not with handles, and traversing on the
one part the openings G in the plate F and, on the other part, the openings made
in a second plate F₁ placed above the plate F. These openings are themselves
covered by covering plates, M, suitably arranged in slides, and which move with
the rods h¹ of the beaters, these latter being connected at their lower ends by

page_text: means of a cross piece H¹, thus allowing of the bottom of the mixture being
agitated. The plate F at the top of the apparatus is held by means of a bayonet
joint f on the external wall of the outer case B, and the latter may, in addition,
have an arrangement of handles P to enable the apparatus to be carried about
more easily.
It is evident that the forms, dimensions and proportions of the accessory parts
may be varied, and the refrigerators may be formed with several moulds or ice
pails instead of one, and the agitators may be operated from the centre or from
the side by an arrangement of beaters, moving on a pivot arranged in the centre
of the internal bottom of the vessel, or by any other suitable system of gearing.
Any suitable materials may also be employed for their construction.
The recipient may also be made with a single wall.
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 I
claim is :-
1. A refrigerating apparatus characterised by the combination of a double
walled receptacle, (in which the ice pail, fitted with its lid or cover, is inserted)
with a system of agitators or beaters passing through openings in the top-plates,
thereby enabling a movement to be communicated to the whole of the refrigerating
substance, such movement being intended to accelerate the fusion of the refrigerating
salts in the water, and to maintain the same temperature in the whole of the
refrigerating substance; substantially as hereinbefore described and shown on the
accompanying drawing.
