COMPLETE SPECIFICATION.
Improved Water Heating Apparatus or "Geyzer" Heated by Gas
Stove, which Stove is adaptable also for Cooking Purposes.
I, THOMAS ROBERTSON of 132 Bothwell Street in the City of Glasgow,
Plumber, 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 improvements in water-heating apparatus by gas stove,
which gas stove is also adaptable for cooking purposes and has for its object the
construction of a form of water heater for baths or any other purpose requiring hot
water which is 1st equally as durable, 2nd more efficient 3rd considerably cheaper
than any other form at present before the public to the best of my knowledge and
4th the simple manner in wbich it can be converted into a cooking stove if such be
desired.
In order that my invention may be clearly rendered reference may be had to
the accompanying sheet of drawings in which
Fig. I is a longitudinal section Fig. II a transverse section Fig. III a plan view
as seen from below.
Figure 4, a plan view as seen from above and
Figure 5, an end elevation of the stove with the water-heating apparatus removed
and ready for cooking.
Similar letters of reference are used to indicate like parts in the various views.
In constructing a water-heater according to my invention I cause the cold
water A from tap or other suitable arrangement to enter a receptacle B (of which
said receptacles there are two at top of the geyzer) & find its way through slot D at
the side into the chamber forming one side of the apparatus (chamber E) This
chamber is in communication with a similar one G on the opposite side by means
of small copper tubes F. which again, are contracted at both ends so that the water
may be delayed in passing through them as the heat of the stove underneath is
mainly concentrated on these tubes. Chamber G is thus filled up and overflows
at the slot H into the second receptacle C. Here the water passes through a
perforated graiting and down the six tubes (i) along underneath the other tubes
directly above the flames and thus into the last chamber which forms the front, and
from which it issues by the tap K ready for use having been raised by its passage
through the heater 90° to 100° F. The gas fumes find their way out at M which
acts as the flue and to which any length of flue pipe may be added or it may be
used without any additional flue whatever. This part of the apparatus already
described is entirely made of copper. The stove which cousists of an iron frame
with brass tubes for the gas N and brass fittings can be utilized as a cooking stove
by simply litting the copper part off and laying on the ribbed plate L as seen in
Figure V.
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 :-
1st. In a water-heater or geyzer the arrangement of the internal tubes in such
silici dannbilion and aboonnase with more afficiency.

page_text: 2nd. In a stove for heating such apparatus the novelty of being able to use it as
a cooking stove also, and that by the simple procedure of lifting off the copper
apparatus and in lieu thereof placing a ribbed plate through which the flames
penetrate, both first and second claims substantially as herein stated & described
with reference to the appended sheet of drawings.
Dated this 1st day of September 1896.
