Complete Specification Left, 4th Apr., 1891-Accepted, 25th May, 1894
PROVISIONAL SPECIFICATION.
Improvement in Apparatus for Heating Water by Gas.
I, JOHN HART, of 13 Gun Street, Reading, Berks, Ironmonger, do hereby
declare the nature of this invention to be as follows:-
A rectangular or square shaped receptacle "A" is supported on a metal
stand "B," with, or without legs, in which a luminous jet, gas-burner is inserted.
Cold water is introduced at the top of the receptacle through a tube "C" which
is so perforated as to discharge a thin stream of water on to the sides of
receptacle "A," & fitted with a spout "D" to discharge water on to a series of
metal plates "E," which are connected together, perforated at ends F, & placed,
as shewn in the accompanying drawing to discharge into an open trough "G," at
point "H."
The trough may be attached to the bottom of the receptacle, or to the base on
which it stands, from thence, the water is discharged, heated, through a spout J.
The whole of the apparatus is so fitted that it can be taken to pieces in a few
minutes, by any ordinary workman.

COMPLETE SPECIFICATION.
Improvement in Apparatus for Heating Water by Gas.
I, JOHN HART, of 13 & 14 Gun Street, Reading, in the County of Berks,
Ironmonger 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 :-
The improvement consists in the construction of a series of metal plates, só
arranged inside a metal vessel, that water, introduced at the top, covers in a thin
sheet all the upper surfaces of the plates, which are heated from underneath by a
powerful jet gas-burner, & is finally discharged through the spout, heated to any
degree, according to the speed with which it is passed through the apparatus.
The drawing lodged with my Provisional Specification shews a perspective view
of the apparatus.
"A." is a metal chamber, which may be shaped rectangular, square, or round, & is
provided with removable cover with hole in centre, to which a pipe can be attached
for carrying off the products of combustion. Cold water is introduced through
tube & spout C, the tube is perforated with holes, to discharge water on to inside
surface of chamber A. Spout C discharges upon top plate E, & covers the whole
of the surface with a thin stream of water, which, passing through perforations,
just within the outer edge F, (which is turned up about ") discharges on to other
plates, "E," below, in succession, which may be, in number, 4, or more, or less,
according to size of apparatus. From bottom plate E the water is discharged into
trough G, from which it is finally discharged in a heated condition, through spout J.
B is a stand for supporting the apparatus, & the gas burner H.
The action of the heating arrangement is as follows, riz.-
The heat from the gas-burner, which is enclosed in chamber A, is male to pass,
as indicated by arrow marks, from the gas burner H upwards between the perforated
end of bottom plate marked E, & metal chamber marked A, under the next plate

page_text: above marked E, rising over perforated end of same, & under the next plate above,
marked E, as before stated continuing its course in the same way under & over all
the other plates marked E, until it is finally discharged through hole in centre of
cover. The vertical lines A. A. A. shew the outline of metal chamber.
Having now, particularly described, & ascertained the nature of my said inven-
tion, & in what manner the same is to be performed, I declare that what I
claim is :-
I. In apparatus for heating water by gas, the use of hollowed or flat plates, with
edges turned up; the arrangement being such as to ensure a thin stream of water
passing over a number of heated surfaces, & finally discharging through the spout
in a heated condition.
II. The apparatus for heating water constructed & arranged, & operating
substantially as herein before described, with reference to, & shewn in drawings, &
furnished with Provisional Specification.
