of Kent Engineer for an Invention of IMPROVEMENTS IN AN APPARATUS FOR
PROVISIONAL SPECIFICATION left by the said Henry Defty at the Office of
the Commissioners of Patents on the 18th October 1883.
HENRY DEFTY of 4 Casella Road New Cross in the County of Kent Engineer
IMPROVEMENTS IN AN APPARATUS FOR HEATING FLUIDS OR RAISING STEAM FOR
ENGINES
This invention relates first to a combined arrangement of vertical or elongated
coil or coils tubes or chambers for the purpose of heating fluids for warming
conservatorys, halls, buildings, or raising steam for engines, (Secondly) The
improved consists of an apparatus with an arrangement of a special mode of
placing one or any number of vertical A or elongated B spiral metallic tube coil
or coils of varied dimensions as to the power or purpose such may be used,
(Thirdly) The construction of those tubes or coils being so consecutively arranged
so as to be equally affected by the radiating heat and to give a uniform strain
upon the joints, which are fixed into a Disc of a round, square, C, or horizontal
chamber D, which I name the Base inlet E & F. in this is fixed a series of tubes
by means of screws or welds according to the class required, The multidudinous
straight or elongated coils are placed in order, so that all their surfaces become affected
and form a complete condenser to absorb all radiant heat that may be generated
at the base where first applied. C. The fluid or steam is then driven up ascending
through the numerous coils into the Dome, H, or discharge main, I, into pipes to
carry off the fluids or steam for use. J. into a sludge or steam trap P. thence to. Q.
This arrangement of coils or tubes is then placed within a case or shell of metallic
metal, Terra Cotta or brickwork, K, L to answer as a protector for the escaping
heat or as a furnace to concentrate all radiant heat from Burners or fire fixed at
the Base G, upon the coils charged with fluid. The multiplex coil or coils straight
B

construction for Gas, or oil is fixed for generating the heat required. The mode of
Gas arrangement which I now describe for heating this apparatus. I name a Duplex
Pyramid Burner. M. the principle of this burner consists of a conical shaped disc
tapering to a certain height from the base with an inverted chamber up the centre
where covered with a wire mesh a mixture of gas and air is admitted in the
stock then to escape thro the outer and inner perforations, into the cap mesh
consecutively arranged for the ignition, affecting a pure combustion at the same
time heating the air and gaseous fuel to a high temperature at the point of
combustion this arrangement gives a great advantage to both heating surfaces and
fuels to effect an immediate result to the fluids or elements to be immediately
heated.

an Order of the Lord Chancellor, filed by the said Henry Defty in the Patent
Office on the 13th May 1884.
HENRY DEFTY of 4 Casella Road New Cross in the County of Kent Engineer
IMPROVEMENTS IN AN APPARATUS FOR HEATING FLUIDS OR RAISING STEAM FOR
ENGINES
My invention is chiefly designed to increase the efficiency of immediately heating
or boiling Liquids, as water or similar elements. The most important novel feature
of this said invention is the arrangement of fixing both vertical and elongated
tubes in a consecutive order so as to absorbe all heat Generated by the tubular or
annular Arrangement of Burners to give an intense momentary effect. But the
said invention also relates to improvements for steam Engine Boilers to adapt
them for more advantageous use both as regards space, expense, simplicity and
safety in general.

carried into practical effect. I wish it to be understood that I do not confine myself
to the exact details of construction as herein described reserving the right of
principal and to modify the same for the purposes herein before named as shewn
in Figures I. 2. 3. 4. 5. 6. of the accompanying drawings.
