An Improved Portable Refrigerator.
I, THEODOR EIGEL, of Schildergasse 36, Cologne a/Rhine, in the Empire of
Germany, Confectioner, do hereby declare the nature of this invention and in what
manner the same is to bo performed to be particularly described and ascertained in
and by the following statement :-
This invention relates to an improved portable refrigerator.
Fig. 1 of the annexed drawing shows a side view and Fig. 2 a vertical section
of the apparatus, and Fig. 3 shows the apparatus provided with a jacket of felt or
the like.
The apparatus consists of a lower part a which may be provided exteriorly with
a projecting bottom border and interiorly at a suitable height with an annular
ledge b having slots or perforations b¹ on opposite sides, and extending to the wall,
of the lower part, in order to give a passage to the water collected there. The
upper part e fits and reaches over the lower part a as far as the arched wall e¹
provided in its interior allows. The upper part is provided on the top with a cover f
with an inside rim, after having removed this cover the upper part can be
filled with ice. The cover f is provided with handles f¹ for easy manipulation of
the same.
For the purpose of connecting the upper and lower part together the latter is
provided with two lugs a' opposite each other, in each of them a brace or strap is
fixed one of which is provided with a handle h fixed thereto the other end of which
is connected to the second brace by means of a buckle h¹. Lateral movement of the
braces is prevented by shoulders a² adapted on the cover.
The upper and lower parts are filled with broken ice, then the plate c provided
with a handle c¹ is laid upon the annular ledge b. Upon the plate c any matter to
be kept cool is placed.
By this arrangement the whole of the interior chamber of the portable refrigerator
with the exception only of the small part between the ledge b and the lower berder
of the intermediate bottom c¹ is surrounded with ice causing a very effective and
advantageous refrigeration of the interior chamber and its contents. Moreover
in consequence of its construction the apparatus is easy to manipulate and also to
clean.
These portable refrigerators intended principally for use for pastry-cooks' and the
like dishes, can be covered with a jacket of non-conducting material as for instance
felt or blanket as shown in section view Fig 3, in order to avoid the influence of the
outside temperature. For this purpose a mantle m of felt or the like material is
put round the apparatus and is fastened by straps m¹ with buckles or in another
suitable manner.
Caps and are placed respectively with their edges over or inside the upper
and lower edges of the mantle m and fastening is made by means of straps k² or the
ike, by this means the apparatus is entirely clothed. The jacket and cover may be
provided interiorly and exteriorly with waterproof material or constructed entirely
of such waterproof material. The carrying braces pass between the jacket m and
he ton can

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. An improved portable refrigerator in which any matter to be kept cool is
placed between the upper part e and the lower part a respectively filled with the
refrigerant so as to be almost completely surrounded by the same.
2. An improved portable refrigerator as in Claim land covered with a jacket of non
conducting material so that the apparatus is surrounded on all sides by the same,
the jacket may be provided interiorly and exteriorly with water proof material or
constructed entirely of such waterproof material.
3. An improved portable refrigerator substantially as described and illustrated
in the accompanying drawing.
