COMPLETE SPECIFICATION filed by the said William Robert Lake at the
Office of the Commissioners of Patents on the 3rd July 1877.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN APPARATUS FOR HEATING
WATER BY GAS." A communication from abroad by Alexander Russell Walker, of
Melbourne, Victoria, Australia, Gas Engineer.
This Invention is designed for the purpose of reducing the cost of heating water
by gas, and is constructed to provide considerable metallic heating surface, and to
allow of the cold water being supplied in a shower to that part of the apparatus
where the heated air is escaping.
In the accompanying Drawing Figure 1 is an elevation of the said apparatus ;
Figure 2 is a vertical section thereof; Figure 3 is a horizontal section on the
line b, b, Figure 2; Figure 4 is a horizontal section on the line a, a, Figure 2; and
Figure 5 is a cross section of supply inlet.
The full line arrows denote the course of the water, and the dotted arrows that
of the gas and heated air.
The said apparatus is constructed entirely of metal, the outer casing A being made
of galvanized iron, and the inner one B of copper; C is the gas supply pipe; D, a
Bunsen" burner; E, a copper basin, connected at its base to the annular water space
between the inner and outer casing by pipes F, and having a discharge pipe G for
the heated water. For preventing the entrance of the water into the inner casing I
provide it with a copper cap or cover H, supported as shewn; and for interrupting
the descent of the water I attach to the outer casing a copper disc J. K is the water
supply pipe, having a taper nozzle, as shewn, to increase the force of the supply
into the chamber L, down which it falls on a hemisphere M, supported by two wires
Paine A1

page_text: connected to said chamber L. The fall of the water on this hemisphere produces a
satisfactory shower without the danger of choking which accompanies a perforated
plate. Descending in this part of the apparatus it abstracts some of the heat from
the escaping heated air, and then falls on the cap H and disc J, trickling down the
outer side of the inner casing B into the annular space between it and the outer casing,
passing through the pipes F into the basin E, and thence through the discharge pipe G
into a bath or other receiver. The supply of water and gas must be so regulated as
to give a continuous discharge of water heated to the required degree.
I prefer to make the parts with the relative proportions shewn in the Drawing.
Having thus fully described the said Invention, as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I do not confine myself to the use of any particular kind of metal in the con-
struction of the said apparatus, as it is more a question of price than suitability as
to the kind of metal used; neither do I confine myself to the use of a hemisphere
for producing the shower, although I believe it to be the best, but I claim,―
First. In apparatus for heating water by gas supplying the water to be heated
in a shower near the part of the said apparatus where the heated air escapes from
the same.
Second. The mechanical combination and arrangement of parts for the purpose of
heating water by gas, as illustrated in the accompanying Drawing, and as herein
described.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Third day of July, in the year of our Lord One thousand
eight hundred and seventy-seven.
