COMPLETE SPECIFICATION.
Improvements in Oil Burners.
I, JOHN HENRY GRAHAM, of Warren, County of Warren, State of
Pennsylvania, United States of America, 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:—
My invention relates to improvements in oil-burners in which petroleum is used
for the purpose of generating vapour and utilizing the same for heat.
My invention is disclosed in the following Specification and claims, and is
illustrated in the accompanying drawings, in which :-
Figure 1 is a vertical section of the entire oil-burner;
Figure 2 a side view ;
Figure 3 a vertical section of a portion of the oil-burner on
Figure 2;
Figure 4 a top view of the retort and the case;
Figure 5a top view of the plate and its openings ;
Figure 6 a top view of the burner.
Similar letters refer to similar parts throughout the several views.
a line 1-2,
The retort A, the case B, nut C, and pipe D, adapted to the pipe H, which is
connected to the burners F F F by means of the pipes G G, all of which are
supported by the frame E, constitute the frame-work of the entire oil-burner. The
retort A is hollow, and has opening a threaded for the reception of the pipe H,
opening, threaded for an extra burner, and opening c, threaded for the insertion
of the pipe I and referred to hereinafter. The case B has straight sides and ends
of equal height, and a flat bottom with an opening d for the reception of the
pipe H. The retort A is inserted in the case B, forming an opening g, which
protects the retort A from direct heat. The pipe D rests upon the top of plate E
and extends to the nut C, incasing a portion of the pipe H, protecting the pipe H
from direct heat. The pipe H is connected to the pipes G G (see Figure 3) and
passes vertically up through the opening d in plate E, thence through pipe D, and
(being threaded from the bottom of the nut C to the top) is adapted to the nut C
and opening a in retort A, into which it is inserted to a point near the opening b, as
in Figure 3. The pipes G G are attached to the lower end of the pipe H, and the
burners F F F are cup-shaped, with openings e e e, also flanges i ii, and adapted to
the plate E which is provided with openings hhh, (adapted to the burners FF F)
also opening d, through which the pipe H is inserted.
In operating the oil-burner the petroleum is flowed through the pipe I into the
retort A, and a fire is then kindled upon the plate E, directly under the case B,
causing the petroleum to vaporize, and the vapour escapes through the pipes HGG,
thence through the openings e é e in the burners FF F, where it ignites and
produces heat sufficient to assure a continuous generation of vapor for heating
purposes, provided the retort A is replenished with petroleum from time to time.
I prefer to show the position of the oil-burner as it would appear in the fire-box

page_text: of a boiler m with the plate E supported by flanges r r r of the boiler m, and also
by a brick wall t, which prevents the draft from passing under and back of the
plate E (see Figures 1 and 2) and forms an air-chamber beneath the plate for
supplying air to the burners."
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I wish it understood that
I am aware that prior to my invention oil-burners have been made with various
burners which vaporize petroleum for heating purposes, operating in conjunction
with receptacles for holding petroleum, I therefore do not claim such a combination,
broadly; but what I do claim is :-
1. In a vaporizing hydrocarbon-burner, the combination, with the supporting-
plate, of the burners located therein, having air-inlets communicating with the open
air below said plate and their discharge ends above said plate, substantially as
described.
2. In a hydrocarbon-burner, the combination, with the supporting-plate, of the
burners located therein, having air-inlets below said plate, and the draft-check
below the plate and forming therewith a closed air-chamber, substantially as
described.
3. In a hydrocarbon-burner, the combination, with the supporting-plate adapted
to be placed in the fire-box of a steam-boiler, of the burners located therein and
supported thereby, the generating-chamber, and the pipes connecting it with the
burners, whereby said burners and chamber and their connections are supported by
said plate, substantially as described.
4. In a hydrocarbon-burner, the combination, with the supporting-plate and
burners, of the generating-chamber, the shield therefor, the pipe connecting the
'said chamber with the burner pipes, and the shield for said pipe between the
supporting-plate and shield for the generating-chamber, substantially as described.
