COMPLETE SPECIFICATION.
A New or Improved Apparatus for Lighting Fires by the Flame of
"Sprayed" Oil.
I, THOMAS CHARLTON, of Haddrick's Mill, Gosforth, in the County of
Northumberland, Engineer, do hereby declare the nature of said invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
My invention relates to a portable apparatus, specially adapted for domestic
use, by which any suitable oil, issuing from a "burner" under pressure of air,
produced by any simple form of pump, and mixed with a portion of such air,
issuing from a surrounding nozzle, is divided into a fine spray, which being ignited
forms a powerful flame, penetrating the body of the fuel, and producing therein in
a few minutes a bright fire without the use of "kindling" wood.
On the accompanying sheet of drawings is shewn to the actual size one form in
which the apparatus may be constructed, Fig. 1 shewing it in vertical section, and
Fig. 2 in vertical external elevation, and this form I propose to use as being light
and easily portable, simple in construction, easy in working, and not liable to get
out of order. I wish it however to be understood that, as to the air pump and to
the connection with the spraying appliance, modifications may be made to suit
varying conditions.
DESCRIPTION OF DRAWINGS.
In
Referring now to the drawings, A. is a pillar, with a foot to stand upon the
hearth, upon which slides adjustably a tube B., forming a prolongation of the air
pump cylinder C., upon which is a bracket D., to support the oil reservoir E.
the tube B. is a diaphragm F., and upon the side is an air delivery branch G. in
which is fitted a valve H. opening upward, leading to the oil sprayer. The air
pump cylinder C. is fitted with a packed piston J., the rod of which is a tube K.
communicating by an air passage L. with the air pump cylinder, and the lower
end has an internal screw thread into which is screwed a valve scat M. with a
valve N. opening downward. The tubular piston rod K. works through a screwed
cap O. at top of the cylinder C., and beyond is fitted with a handle P. by which it
is operated. The piston is fixed on the rod by a ferrule Q. pinned through the
rod, and above this is the air passage L. from the cylinder C. through which air
sprayer,"
passes down through the valve N. and up through the valve G. to the "
the external air entering the cylinder by the passage S. at top.
The "sprayer" consists of an internal oil tube T. the lower end of which is
immersed in the oil in the reservoir, and leads upward to a diminishing nozzle
(forming the burner) U. and an annular air tube V. with a belt around it into
which air is forced by the pump and passes down into the reservoir to force up the
oil, or upward only to the nozzle to draw up the oil by induced suction, or partly
each way. This annular air tube opens into the oil tube T. behind the nozzle U.
to mix with the oil and form the spray.
The action of the apparatus is as follows:-
The apparatus having been adjusted to the height of the grate by moving it up
or down upon the pillar A., and fixing it by the "set-screw" and, the piston being
drawn upward, the valve N. opens and, the valve H. simultaneously closing, air

page_text: passes to the underside of the piston, which being then forced downward, the
valve N. closes and, the valve II. simultaneously opening, the air passes through it
and up the annular tube V. to the sprayer, drawing up the oil in the tube T. by
induced suction, or the air may pass partly upward and partly downward into the
oil reservoir E. and so force the oil to the nozzle burner U. whence the air, mixed
with the oil, issues in a fine spray which being ignited streams in a flame amongst
the fuel in the grate, till it is in a permanent glow throughout when, the operation
of the pump ceasing, the flume at the burner is extinguished.
Having now particularly described and ascertained the nature of said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1st. An apparatus for lighting fires by the flame of "sprayed." oil mixed with
compressed air, consisting of an air compressing pump, of any simple construction,
forcing or drawing oil and air to the nozzle or burner of a "sprayer" in such
manner that they are mixed and issue in a fine spray, which being ignited forms
an intense flame, penetrating amongst the fuel in the grate, substantially as
described.
2nd. The apparatus comprising in combination the air compressing cylinder C.
prolonged to slide upon the pillar A. and adjustable thereon, carrying the oil
reservoir E.; a branch G. fitted with the valve H.; a piston J. with a hollow
rod K. fitted with the valve N; air passages S. and L. into the air cylinder and
thence into the hollow piston rod; a "spraying" implement comprising an oil
tube T., with a nozzle burner U., enclosed by an annular tube V., the whole
constructed and operating substantially as herein before described and as shown by
the drawing.
