COMPLETE SPECIFICATION.
An Improved Heater for Food and the like.
I, GUSTAV LEBERECHT HINDERER of 1225 Cass Street, Philadelphia, in the
County of Philadelphia, and State of Pennsylvania, United States of America,
Tinsmith, 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 consists of a heater for food, dishes, &c., formed of a heating-
chamber with a water reservoir around the same, as will be hereinafter set forth
and definitely claimed.
Figure 1 represents a perspective view of a heater embodying my invention.
Fig. 2 represents a longitudinal vertical section thereof.
Similar letters of reference indicate corresponding parts in the two figures.
Referring to the drawings, A designates a water-reservoir formed of a metallic
casing with preferably double side walls B, a bottom C, and a lid D with an
air-space therein.
In the reservoir is a metallic oven or chamber E, which is tightly closed on top,
sides, and back, and it joins the front wall of the reservoir aside of the opening F
therein, where access is had to said chamber in order to insert and remove food,
dishes, &c., into and therefrom, said opening being closed by a suitable door G.
Between the top wall of the chamber E and the bottom of the lid D is an air-
space, so that said chamber has surrounding it on all sides an open space, except
on the bottom thereof.
The operation is as follows:
Water is placed in the reservoir A. and the device placed upon a stove, range, &c.,
whereby the water may be heated, or if previously hot the heat may be maintained.
This heats the chamber E, whereby articles therein may be warmed or heated and
kept so, and the device may be placed in a dining-room, saloon, &c., so that the
articles as required may be removed therefrom or the device may be used for
"sending out" meals, &c.,-a matter of convenience and service-as the chamber
retains its heat as long as the water remains hot or warm, it being noticed that the
water is not exposed to the atmosphere, so that its rapid cooling is prevented.
Besides this there is a supply of hot water when so required, the same being readily
drawn off by the faucet H, which is suitably connected with one of the walls of the
reservoir.
In the lid D is an automatically acting valve J, which opens outwardly to permit
the escape of steam in the reservoir A when the same is excessive, thus preventing
explosion. The bottom C is extended beyond the sides B, and the latter are
flanged outwardly, as at K, the flanges being embraced by the extended ends of
the bottom, which ends are bent over the flanges, thus forming lap-joints L,-which
firmly connect the bottom and sides, as most clearly shown in Fig. 2,

page_text: Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A heater having a water reservoir with double side walls and a lid, a heating
chamber within said reservoir, having an open space on its sides and top, and a door
connected with the side of the reservoir and opening into said chamber, said parts
being combined substantially as described.
2. A heater consisting of a water reservoir having the double side walls B,
the bottom C, and the lid D, the metallic chamber E within said reservoir, with
the opening F therein, having the door G, opening outside the reservoir, and the
faucet H, leading from the said reservoir, said lid D having a valve for the escape
of the steam, said parts being combined substantially as described.
Dated this 24th day of November 1892.
