page_text: We, ROBERT FREDERICK BALLANTINE, Master, and WILLIAM SHAW UNSWORTH,
Engineer, both of the Manchester Workhouse, Crumpsall, Manchester, in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
'
This invention has reference to a non-circulating water heater in which the
water is heated through its coming into direct contact with steam previous to its
issuing from a nozzle, and the object of this invention is to obtain a simple, inex-
pensive and efficient apparatus.
Our improved apparatus consists of an oblong vessel preferably of cylindrical
form, into one end of which is led a pipe for conducting steam thereinto and
through the side of the vessel is led the water supply pipe. The interior of the
vessel is fitted with a closed perforated metal cage or its equivalent between which
and the sides of the vessel the water can pass. The cage is filled with small pieces
of suitable material, preferably metal balls such as duckshot.
Below the vessel there is a small chamber formed with a contracted or waisted
centre part and a perforated bottom. The perforations in the bottom lead to the
outlet nozzle. which is of any suitable form, but in some cases somewhat in the
form of the roman letter S so as to have a zig zag passage through.
Valves are provided in the water and steam supply pipes by which the heat of
the water issuing from the nozzle can be regulated.
The whole apparatus is constructed in such a manner that the parts may be
easily removed for renewing and cleaning.

page_text: County of Lancaster, 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 has reference to a non-circulating water heater in which the
water is heated through its coming into direct contact with steam previous to its
issuing from a nozzle, and the object of this invention is to obtain a simple; inexpen-
sive and efficient and at the same time comparatively noiseless apparatus.
In order that our invention may be more readily understood we have attached
hereunto a sheet of drawings to which we will now refer.
The drawings represent a sectional elevation of our improved apparatus, com-
bined with a bye-pass arrangement by which steam alone has a free passage
through to the nozzle of the apparatus when required.
Our improved apparatus consists of a closed vessel a of preferably oblong and
cylindrical form. The interior of the vessel is provided with a closed cage b
having preferably small perforations 61 which cage is of suitable size to leave
clearance space 62 between it and the wall of the vessel a so that water can pass
around the cage and enter thereinto through the perforations. Below the vessel a
is formed a compartment a¹ having a contracted centre part a³ and a perforated
loose bottom a³. The lower part at of the compartment a¹ is cylindrical and
screwed to receive a union cap or nut a on which is formed the outlet nozzle a
of the apparatus. This nozzle as is thus easily removeable and in some cases
where a larger volume of water is required or where steam in large volume alone
is required a hose pipe is coupled up to the lower part at of the vessel. The cap 63
of the cage b is made so as to be readily removeable. The cage is charged with
loose material c of a suitable nature so as to delay the passage of steam and water
therethrough. Preferably we employ duck shot as being most convenient to obtain.
Steam enters the apparatus through an orifice d formed above the top of the cage,
and in its passage through the apparatus is delayed by having to pass through
the interstices formed by the charge of shot. Water enters the vessel a by the
orifice e formed preferably at the side of the apparatus, and in its passage to the
nozzle has also to pass through some of the perforations in the cage b and through
the charge of shot where it mingles with the steam and so becomes heated
and issues quietly.
Sometimes we employ in connection with the apparatus a bye pass arrangement
which consists in arranging a cock or valve f at the entrance of the steam into
the vessel a so as to shut off that entrance for the steam, a pipe g for conducting
the steam to a nozzle or orifice g¹ in the compartment a¹ and a cock or valve g³
interposed in the pipe g between the cock or valve f and the nozzle g¹, by which
arrangement when the cock or valve f is closed and the cock or valve g³ opened
steam alone is ejected from the apparatus at the nozzle a6 or part a' when the
nozzle is removed. At the orifice e a cock or tap h is arranged in order to regulate
the water supply. The quantity and heat of the water delivered can thus be
regulated within wide limits and either cold water alone or steam alone can be
delivered by operating the cocks in accordance with the end desired.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
-
First: In a water heater the use of a closed perforated vessel or cage charged
with duckshot or other suitable chequerwork so arranged that steam and cold
water are directed through it for the delivery of hot water at the nozzle of the
heater, substantially as hereinbefore described and illustrated in the annexed
sheet of drawings.
Second: The improved construction of water heater which consists in the
arrangement of a cage containing chequerwork, in a closed vessel having a steam
inlet above the cage, a water way round the cage with inlet thereto and an out-
let having a contracted passage below the cage so that the steam and water must pass

page_text: through the cage and chequerwork on their way to the outlet nozzle substantially
as hereinbefore described and illustrated in the annexed drawings.
Third: The improved construction and arrangement of parts forming a water
heater substantially as herein before described and illustrated in the annexed sheet
of drawings.
