Improvements in Water Heaters.
I, JOSEPH GERHARD AMANDUS JUNK of 59 Ritterstrasse, Berlin in the
German Empire, Engineer and 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 :-
This invention relates to water heaters of the water tube type and its objects are
to render such heaters more compact, to provide them with a large amount of
heating surface, and to diminish the spaces within which explosive gases or products.
of combustion might accumulate.
A water heater constructed according to this invention consists of two or more
vertical water chambers connected together by suitable tubes. The accompanying
drawings to which I refer hereinafter, illustrate different types of heaters embodying
my improvements.
Figures 1 and 2 illustrate vertical sections of one form of heater taken at right
angles to each other.
Figure 3 shows a modified form of heater in vertical cross section.
Figure 4 similarly illustrates a further modified form of heater.
Similar letters of reference are used to indicate similar parts where they occur
in the different figures.
The heater shown in Figures 1 and 2 consists of two vertical water chambers k¹
and which are in communication with one another through the series of small
tubes r. These tubes offer a large heating surface and are placed as close
together as possible so as to leave very small spaces in which an explosive gas
might accumulate. The risk of explosion within the fire space of the heater is
thus greatly diminished even if it is not entirely obviated. a is the water inlet pipe
controlled by the valve v and d is the outlet pipe. The heating may be effected
by any desired fuel, but it is preferred to employ gas, which is supplied to the
burner B through the pipe b and the tap 9. The heater is surrounded by a
hood H in which the products of combustion are collected and conducted to the
Blue S.
The heater represented in Figure 3 is intended for dealing with larger quantities
of water and consists of two of the heaters previously described combined together
and in communication with each other through the tubes m and n. Two burners B
are employed. It will of course be understood that more than two of the beaters
may be similarly combined.
In the modified form of heater illustrated in Figure 4 the parallel vertical water
chambers are provided with tubes which have closed ends and project into the
space between them. Tubes r allow communication between the two chambers.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. A water heater consisting of two or more vertical water chambers connected
together by a series of cross tubes, substantially as herein before described and aa
illustrated by the accompanying drawings.
2. A water heater consisting of two or more vertical water chambers provided.

substantially as herein before described and as illustrated by the accompanying
drawings.
