page_text: I, FELIX KAHN, of 133, West 89th Street, in the City of New York, (Borough
of Manhattan), in the County and State of New York, United States of America,
do hereby declare the nature of this invention to be as follows:
:-
My invention relates to apparatus for retaining heat, and has for its object to
provide a receptacle for victuals wherein the same may be kept heated after their
removal from the stove or fire.
The outer shell of the apparatus consists of an ordinary kettle provided with
a cover secured by means of hasps and which engage with staples upon the kettle.
Within the kettle adjacent to its inner side and bottom, is provided a lining of
asbestos or analogous material and adjacent to the vertical portion of the said
lining is disposed a circular corrugated partition whereby an air-space is main-
tained between the outer shell or kettle and the interior of the apparatus.
Within the kettle near its top is arranged an annular shelf which is provided
at intervals upon its upper surface with hooks for the attachment of a pouch
of felt or analogous material which is suspended within the kettle. Within
the pouch is placed an inner receptacle adapted to receive the victuals or other
matter to be maintained warm, said receptacle being provided with a cover.
A filling of loose hair, felt or other non-conductor of heat is interposed between
the outer surface of the pouch and the inner surface of the circular corrugated
partition and the base of the outer shell.
Between the cover of the inner receptacle and the annular shelf surrounding
the same and the cover of the outer shell is interposed a casing of felt filled with
hair or analogous material and between the pad and the underside of the cover
is interposed a lining of asbestos, both the pad and lining being secured to the
under side of said cover by rivets.

I, FELIX KAHN, of 133, West 89th Street, in the City of New York, (Borough
of Manhattan), in the County and State of New York, United States of America,
Inventor, 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 relates to apparatus for retaining heat and has for its object to
provide a receptacle for victuals wherein the same may be kept heated after their
removal from the stove or fire.
To this end my invention consists in the novel details of construction and the
combination, connection, and arrangement of parts, as hereinafter more fully
described, and then pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar characters of reference indicate corresponding
parts in both the figures.
Figure 1 is a central vertical section of an apparatus constructed according
to and embodying my invention, said section being taken on the line 1-1 of
Figure 2; and
Figure 2 is a section partly broken away, taken on the line 2-2 of Figure 1.
In said drawings, A designates a sheet metal kettle of ordinary construction,
which constitutes the outer shell of the apparatus, B denotes the cover for said
kettle or shell A, said cover being provided with hasps C_C, adapted to engage
the staples D D on the kettle A to maintain the cover B in position thereon.
Within the kettle A, adjacent to its inner side and bottom, is provided a
lining E of asbestos or analogous material, and within said kettle A, adjacent
to the vertical portion of the said lining E, is disposed a circular corrugated
partition F, whereby an air-space is maintained between the outer shell or
kettle A and the interior of the apparatus.
Within the kettle A, near its top, is arranged an annular shelf G, which is
provided at intervals upon its upper surface with hooks a, and H denotes a
pouch, made of felt or analogous material, provided upon its outer surface, near
its upper edge, with loops b, adapted to engage the hooks a on the annular
shelf G, whereby to maintain said pouch H in position within the kettle A.
I denotes the inner receptacle, adapted to receive the victuals or other matter
to be maintained warm, said receptacle being provided with a cover J, and
K denotes a filling of loose hair, felt, or other analogous substance which does
not conduct heat, interposed between the outer surface of the pouch H and the
inner surface of the circular corrugated partition F and the base of the outer
shell A.
L denotes a pad composed of a casing of felt filled with hair or analogous
material, and M denotes a lining of asbestos interposed between the pad L and
the under side of the cover B. The pad L is interposed between the cover J
of the inner receptacle and the annular shelf G, surrounding the same and the
cover B of the outer shell, and both the pad L and lining M are secured to the
under side of said cover B by rivets c.
Having now particularly described and ascertained the nature of my said
invention; and in what manner the same is to be performed, I declare that what
I claim is:-
1. An apparatus for the purposes specified. comprising an outer shell 9

page_text: cover therefor, a lining of non-conducting material, arranged therein, a corru-
gated partition arranged within said shell adjacent to its vertical side, an annular
shelf disposed within said shell, adjacent to its upper edge, a pouch, means for
securing the same at its upper edge to said annular shelf, a filling of non-con-
ducting fibrous material interposed between said pouch and the outer shell, a
receptacle disposed within said pouch, a cover therefor, and filling of non-
conducting material interposed between the top of the inner receptacle, and shelf
surrounding the same, and the under side of the cover of the outer shell, sub-
stantially as specified.
2. An apparatus for the purposes specified, comprising an outer shell or recep-
tacle, a cover therefor, and means for securing said cover to said outer shell or
receptacle, a lining of asbestos arranged within said outer shell or receptacle,
adjacent to its base, side and cover, a circular corrugated partition arranged
within said outer shell or receptacle, adjacent to the inner vertical side thereof,
and extending almost to the top of said outer shell or receptacle, an annular shelf
disposed within said outer shell or receptacle adjacent to its top, hook members
provided thereon upon its upper surface, a pouch composed of felt provided along
its upper edge with loops adapted to engage the hooks on the annular shelf, a
filling of loose non-conducting fibrous material interposed within the outer
shell between the pouch and the base end side of the outer shell or receptacle,
a receptacle disposed within said pouch, a cover for said receptacle, and a pad
of non-conducting material interposed between the cover the last mentioned
receptacle and the shelf surrounding the same, and the under side of the cover
of the receptacle first mentioned, said pad being secured to the under side of the
cover of the receptacle first mentioned, substantially as specified.
