PROVISIONAL SPECIFICATION.
Novel Construction or Arrangement of Water Heaters (Geysers).
I, WILLIAM DYSON WANSBROUGH, of St. Catherine's, Lincoln, Engineer do
hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of water heaters in column form from
two tapered tubes these having a spiral partition between them for directing the
water to be heated upwards and spirally, the inner of the two tapered tubes being
provided with cross tubes at intervals and at an angle for ensuring perfect circulation
and a rapid heating from a gas flame arranged at the base. By this invention from
the tapered inner tube and the cross tubes the heat and products of combustion are
retarded while expanding and their heating properties absorbed by the apparatus
before the vapour escaping can pass through a contracted opening at the head of the
column.

COMPLETE SPECIFICATION.
Novel Construction or Arrangement of Water Heaters (Geysers).
I, WILLIAM DYSON WANSBROUGH, of St. Catherine's, Lincoln, Engineer, 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 the construction of water heaters in column form from
two tapered tubes, these having a spiral partition between them for directing the
water to be heated upwards and spirally the inner of the two tapered tubes being
provided with cross tubes at intervals and at an angle for ensuring perfect circulation
and a rapid heating from a gas flame arranged at the base.
By this invention from the tapered inner tube and the cross tubes the heat and
products of combustion are retarded while expanding and their heating properties
absorbed by the apparatus before the vapour escaping can pass through a constructed
opening at the head of the columu.
My invention will be clearly understood by the aid of the annexed sheet of
drawings in which Figure 1 shows a part sectional elevation, Figure 2 an exterior
elevation, and Figure 3 a cross section on the line a, a, of Figure 1.
The invention as before stated consists of two tapered tubes A, B, with a spirally
arranged partition C between (in touch or nearly so with both tubes A, B,) and
with cross tubes D in the hollow of the inner tube B, the tubes D being set at an
angle and form connecting passages to effect a circulation of the water in addition
to that accomplished by uprising action of the water in the spaces between the
spiral wrapping.
The water is fed from the inlet pipe E at the lower part of the column and finds
an outlet from the swelled portion or gallery F at the top of the column by the

page_text: The upper part of the inner tube B has a cap H with a contracted opening I for
limiting the passage of the escaping vapour of the products of combustion arising
from a gas flame (preferably air gas from what is commonly known as the "Bunsen
burner) in the tube J. The available products from said flame are checked or
retarded by the cross tubes D, D, and this causes all possible heat to be imparted
to those cross tubes and to the inner tube B for warming the water flowing through
the tubes and between the spirals while travelling upwardly to the gallery F, the
water being in thin film like form for rapidly taking up the heat.
To facilitate a cleaning of the apparatus, I provide the lower part of the outer
shell A with a flange K for screwing down upon a flange L of the gas stove M,
and on removal of the screws the shell A. is readily removed and as readily replaced
when desired.
The water inlet and outlet pipes E, G, are provided with taps to regulate the
quantity passing through, and these taps in conjunction with that of the gas supply
enables a person to determine and regulate the heat of the water for the purpose
for which it is required.
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. The novel construction and arrangement of apparatus as represented on the
annexed drawings for the purpose described.
2. The combination of two tapered tubes A, B, intervening spiral partition C,
cross tubes D, D, in flueway of inner tube B surmounting a gas stove M the whole
being arranged, constructed, and adapted for the purpose of rapidly heating water
while in transit from the lower to the upper part of the apparatus, as set forth.
