PROVISIONAL SPECIFICATION left by the said George Shaw at the
Office of the Commissioners of Patents, with his Petition, on the 25th
May 1864.
I, GEORGE SHAW, of Birmingham, in the County of Warwick, Patent Agent,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUS FOR HEATING THE STEAM BOILERS OF STATIONARY, LOCOMOTIVE, AND
MARINE ENGINES, FOR HEATING STOVES, AND FOR HEATING PURPOSES GENERALLY,"
to be as follows:-
The said Invention consists in constructing and arranging or combining,
essentially in the manner herein-after explained, the parts of apparatus for
heating steam boilers and stoves by the combustion of petroleum oil or other

page_text: liquid volatile hydrocarbon, which said apparatus is also applicable for heating
purposes generally.
The said Invention consists in constructing and arranging a series of burners
and deflectors or air conductors either in circles or concentric circles, or in
straight parallel lines, and in the same or in different planes, so that a perfect
combustion of the petroleum oil or other liquid volatile bydrocarbon supplied
to the burners is effected, and the series of flames so lengthened and expanded
as to form a continuous sheet or sheets of flame. The burners may either be
situated horizontally or vertically, or at such an angle as the purpose to which
they are applied requires. In applying the said Invention to the heating of a
steam boiler the reservoir or reservoirs containing the petroleum oil or other
volatile bydrocarbon are placed in or near the furnace or fire-box of the said
boiler, and the sides of the said reservoirs are made hollow and filled with
water, so as to keep the said reservoirs cool and prevent the volatilization of
the petroleum oil by the heat of the apparatus; or the reservoirs may be.
situated at a distance from the burners. A series of horizontal tubes arranged.
in circles or in concentric circles pass from the reservoirs, and to each of the
said horizontal tubes a burner, made by preference of porcelain, is affixed.
Each burner is supplied with a wick of the ordinary kind, and the pinions for
raising and lowering the wicks are so geared together that the whole of the
wicks can be raised or lowered simultaneously. Around each of the burners,
and at a short distance therefrom, is a conical deflector or air conductor, and
between the said deflector and burner air passes to support the combustion of
the flame. The said deflector or air conductor is open at top and bottom, its
open summit being situated just below the top of the burner. Concentric
with the said deflector are two other conical deflectors or air conductors open
at top and bottom. The openings in the summits of these deflectors or air
conductors are concentric with the burner; the summit of the smaller of the
last-mentioned deflectors is above the wick, and the summit of the second or
outer deflector of the last-mentioned deflectors is at a still higher point above
the wick. The series of deflectors described cause such a draught of air
through the burners that the flames after passing from out the top of the
outer deflector are expanded in breadth, and the series of flames is made to
coalesce or combine and produce a series of concentric sheets of flame. No.
air has access to the flame excepting by the said deflectors. The deflectors or
air conductors described are carried by a plate connected to the fire-box of the
boiler. The heated air from the burners passes through the flues or tubes
of the boiler in the ordinary way and heats the water in the said boiler. By
constructing and arranging the parts of the apparatus in the manner described

page_text: perfect combustion of the volatile bydrocarbon results, and an intense heat is
produced. In applying the said Invention to stoves and kitchen furnaces the
burners and series of deflectors are placed vertically, the reservoir containing
the petroleum oil being situated at the bottom of the stove or on the bed of
the kitchen furnace. The arrangement of the burners and deflectors is essen-
tially the same as that described with reference to boilers, excepting that one
circle of burners is sufficient. In addition to the conical deflectors or air
conductors causing draughts of air through the burners and expanding and
lengthening the flames, one side of the said deflectors may be so arranged as
to deflect the flame out of the horizontal or vertical line of the burner. Instead
of employing a series of burners and deflectors or air conductors arranged in
circles or concentric circles the burners and deflectors may be arranged in
straight parallel lines in the same plane or in different planes, so as to produce
a series of parallel continuous sheets of flame either in the same plane or in
different planes.
