PROVISIONAL SPECIFICATION.
An Improved Apparatus for Generating Steam, Heating Water, and
analogous purposes.
We, WALTER JOHN MILLINGTON, of 5, St. Mary's Terrace, College Park, London,
N.W., Engineer, and WILLIAM GEORGE CANNON, of 107, London Road, Southwark,
London, S.E., Gas, Steam, and Hot Water Engineer, do hereby declare the nature
of our said invention to be as follows:-
Our invention relates to apparatus in which water is caused to circulate by
heat the water being contained in tubes and its object is to effect certain improve-
ments therein or relating thereto.
According to our invention we construct the improved apparatus with three main
horizontal tubes triangularly arranged and connect the two lower tubes with the
upper tube by means of a number of smaller diagonally_arranged tubes. The
two lower tubes are fed with water by a suitable union or T piece connection and
the upper tube is connected with an outflow pipe or the like these pipes being in
connection with a radiator bath hot water cylinder or any other vessel or appa-
ratus required to be heated or supplied with heated water or for generating steam.
All the pipes are preferably formed of solid drawn metal.
We enclose the tubulous boiler in a double metallic casing the inner casing
forming the walls of the combustion chamber and the outer casing forming a
jacket to the inner casing thus providing a chamber for heating the air as it
passes to the burners. The air enters the outer casing at the top through a
number of holes slots or other suitable passages. In passing downwards to the
burners the air absorbs caloric and reaches the burners in a highly heated state
whereby economy of fuel is secured. The boiler is heated preferably by a Bunsen
gas burner consisting of the usual mixer jointed to two branch pipes having a
number of holes jets saws cuts, or the like. The combustion chamber is fitted
with a chimney or flue which carries off all deleterious products of combustion
but paraffine petroleum or other oils may be used as fuel in place of gas.
The construction of the double chamber also prevents down draught and admits
sufficient fresh air to allow of perfect combustion.

page_text: London, S.E., Gas, Steam, and Hot Water Engineer, do hereby declare the nature
of our said invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement: _
Our invention relates to apparatus in which water is caused to circulate by
heat, the water being contained in tubes, such apparatus being also adapted for
generating steam; and its object is to effect certain improvements therein or
relating thereto.
And in order that our said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, in which similar
figures of reference indicate corresponding parts.
Fig. 1 is a perspective view of one form of our invention.
Fig. 2 is a transverse section of the same.
Fig. 3 is a longitudinal sectional elevation of Fig. 1.
Fig. 4 is a sectional elevation of a modification of our invention, looking towards
the back end.
Fig. 5 is an elevation of another modification, of the arrangement of tubes.
Referring to Figs, 1, 2, and 3, 6 is the outer casing and 7 the inner casing; the
two casings being placed at a suitable distance apart to form air heating cham-
bers, 8, 8. The inner casing 7 forms the walls of the combustion chamber 9.
10, 10 are two perforated limbs of a Bunsen burner, supplied with gas and air
at 11. Air enters the heating chambers 8 through perforations 12, 12, formed
in the upper part of the casing 6 from whence it descends in a heated state to the
central opening 13. The lower ends 7, of the casing 7, are specially designed
to protect the burners 10, and thereby produce steady flames which are not liable
to be extinguished, the heated air passing the plates 7 to the burners.

with the inflow. 18 is a horizontal tube in connection with the flow pipe 15.
19, 19, are two sets of diagonally arranged tubes communicating with the hori-
zontal tubes 17 and 18. The tubes 17, 18 and 19, constitute an efficient amount
of heating surface for heating water or generating steam. 20 is the inspection door,
and 21 the flue for conveying away the surplus gases.

Figs. 4 and 5 illustrate modifications of our invention, the air heating chamber
being vertically arranged between the outer casing 6 and inner casing 7. 10 is
the Bunsen burner. The heating pipes 19 may be straight, as shown in Fig. 4
or coiled, as shown in Fig. 5.
In the modification shown in Fig. 4 the casing may be cylindrical, conical,
square, hexagonal, or of any other suitable section, and the water tubes or cham-
bers 17 and 18 similarly varied in form to correspond therewith. The pipes 14
and 15 may be fitted in connection with a radiator, bath, hot water cylinder, or
any other vessel or apparatus required to be heated or supplied with heated water
or for generating steam.
In applying our invention to baths and the like, we sometimes pass the water
to be heated through the pipe 15 and let the heated water pass outwards through
the pipe 14, as practised with what are known as geysers."
«
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. In apparatus for the purposes aforesaid, the combination of an enclosed air-
jacketed combustion chamber, arranged to take in air from the upper part of the
jacket, whereby the air is fed to the burners in a highly heated state at the lower
part of the combustion chamber; water tubes forming heating surface for the
absorption of caloric and circulation of water or generation of steam, substan-
tially as herein before described and illustrated by the drawings.
2. In apparatus for the purposes aforesaid, the combination, with an air heat-
ing chamber or jacket 8, of horizontal tubes 17 and 18 and diagonal tubes 19

plates 7 being fitted so as to form screens to the burners and prevent the flames
being extinguished, substantially as herein before described and illustrated by
Figs. 1, 2 and 3, of the drawings.
3. In apparatus for the purposes aforesaid, the combination, with an air-heating
chamber or jacket 8, of diagonal tubes 19 communicating with a tube 17 and
chamber 18, substantially as herein before described and illustrated by Fig. 4 of
the drawings.
4. In apparatus for the purposes aforesaid, the combination, with an air heat-
ing chamber or jacket 8, of coiled tubes 19, communicating with a tube 17 and
chamber 18, substantially as herein before described and illustrated by Fig. 5
of the drawings.
