Improvements in or relating to Vapour Burners.
We, CHARLES AUGUSTUS STOCKSтвом, of 414, North Broadway, St. Louis,
Mi, United States of America, and LOUIS STOCKSIRом, of 827, Chouteau
Avenue, St. Louis aforesaid, Manufacturers, 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:-
This invention relates to certain improvements in or relating to vapor burners
using coal oil as a fuel.
The invention consists in features of novelty hereinafter fully described and
pointed out in the claims
Fig. I is a front elevation of the stove
Fig. II is an end view with the frame of the stove in section
Fig III is an enlarged vertical section of one of the feed pipes.
Fig IV 18 a vertical section of one of the burners.
Fig. V is a horizontal section taken on line V-V, Fig. IV.
Fig VI is a top view of the base of one of the burners with the vaporizing cup
in position
Irepresents the frame of the stove consisting of a top shelf 2, a back piece 3, a
table 4 and supporting legs 5 strengthened by braces 6
7 represents the burners, of which there may be one or more, resting upon a
support 8 connected to the legs 5 Duectly over the burners the table 4 is pro-
vided with open spiders 9 to receive the vessel or other object being heated
10 represents the oil tank supported over this shelf 2 on a horizontal pipe 11 to
which it is connected by a vertical pipe 12 The horizontal pipe 11 is provided
with needle valves 13 located in short transverse pipes 14 having nipples 15 that
enter the upper ends of the feed pipes 16, as shown in Fig III. The needle
valves 13 rest in notches in a bracket 17 mounted on the shelt 2 and the nipples 15
fit loosely in the pipes 16 so that the tank can be lifted off, with the needle valves,
to be filled.

The pipes 16 extend down behind the back piece 3 and are made quite large
down as far as the table of the stove so that as the oil drops from the nipples 15
it falls by giavity, without coming in contact with the pipes, until it reaches a
point where it has to move in a horizontal direction toward the burners By
thus permitting the oil to descend by gravity, without coming in contact with the
pipes, during its vertical movement, which comprises the greater amount of its
movement from the tank to the buiner, the feed of the oil is rapid, while the tank,
with its needle valves, is located a considerable distance from the buiners In
this way neither the needle valves nor the oil are affected by the heat of the
buiners and the flow of oil through the needle valves remains practically regula
after being adjusted by the operator Heretofore it has been the practice to
locate the needle valve near the table line of the stove thereby bringing it close to
the buine. In this position it is more or less exposed to the heat of the buiner,
which affects the adjustment of the valve and as a consequence the flow of the oil

page_text: through it The oil close to the needle valve, before passing through it, is also
affected by the heat of the buiner, adding another cause for irregularity of the
flow of the oil through the needle valve. From the lower ends of the enlarged
pipes 16 smaller pipes 18 extend to near the burner These pipes 18 are not made
large to the reason that the oil could not pass through them by gravity with-
out touching them, as they are not in a vertical position The lower ends of the
pipes 18 enter short pipes 19 connected to the vaporizing cups of the burners as
hereinafter shown, so that the oil passes from the pipes 18 into the pupus 19
and at the point of connection between the pipes, the pipes 18 may be provided
with hoods 20 to guard the joints between the pipes
The construction of the buiners 18 illustrated in Figs IV, V and VI
21 repre-
Bents the base of the burner which consists of an outer cylinder 22, an inner
cylinder 23, a cential tube 24, a slotted diaphragm 25 and bars 26, located above
the slotted diaphragm The cylinders 22 and 23 are open at the bottom to
permit air to pass up through the slotted diaphragm, and to prevent too much
air passing up through the inner cylinder there is located a disk or plate 27
beneath the cylinder which has a central opening 28 that permits a requisite
amount of air to pass through
29 represents an annular cup that rests on the bars 26 and which forms a vapor-
izing chamber or channel. This cup is open in the center as shown at 30, and it
has an outer flange 31, an inner flange 32 and a depression 33 in its bottom. The
cup has connected to it the portion of the supply pipe 19 with which the pipe 18
connects as already stated
Resting on the cup 29 against the flange 32 is an inner perforated cylinder 35
and resting on the cup against the flange 31 18 an outer perforated cylinder 36,
these cylinders 35 and 36 being surrounded by an imperforate cylinder 37 that
is open at top and bottom and the lower end of which fits over the upper end of
the base 21 The cylinder 36 is open at top, while the cylinder 35 has a closed
top 38
Within the cylinder 35 is an upper imperforate diaphragm 39 and a
lower perforated diaphragm 40 Beneath the diaphragm 40 is a disk 41 of less
diameter than the inside of the cylinder 35 and which 18 suspended from the
diaphragm 39 by rods 42
43 represents a pipe open at both ends and which extends up through the
tube 24 and into the cylinder 35 to a point above the diaphragm 39. The cylin-
ders 36, 36 and 37 and the pipes 43 aie fastened together by bolts 45 as shown
in Fig. IV.
Within the cup 29 is a 11ng 46 of absorbent non-combustible material such as
asbestos This ring is for use in initially heating the burner.
Beneath each buinei there 18 a lever 47 secured to a rock shaft 48 having
also an arm 49 with a projection 50 that extends into the open end of the pipe 43 4
The pipe 43 fits loosely in the tube 24 and by pressing on the outer end of the
lever 47 the pipe 43, carrying the cylinders 35, 36 and 37 with it, is raised so as
to lift the cylinders vertically away from the vaporizing chamber so that a match
can be applied to start the burner. When the level 18 released the pipe 42 guides
the cylinders back to their normal position
The operation of the burner is as follows;
As
A small amount of oil is allowed to pass into the vaporizing cup, by opening
the needle valves 13 of the burner to be started, and a match is applied to the
ring 46, which has absorbed the oil that was admitted to the cup The oil burns
on the ring as on the wick of an ordinary lamp, and heats the vaporizing cup à
and after the cup has become heated, the oil is turned on more, the needle valves
being opened sufficiently to allow the oil to drop faster from the nipple 15
the oil comes in contact with the hot cup it vaporizes and the vapor being heavier
than the atmosphere flows by gravity around the cup and as it becomes mixed
with oxygen it rises into the space between the cylinders 35 and 36 where com- 5
bustion takes place and there is maintained a blue flame at the top of the burner.
By providing the diaphragm 39 the air entering the cylinder 35 through the

page_text: perforated diaphragm 40 is compelled to pass out of the cylinder 35 before it
reaches the top of the cylinder thus aiding in the mixing of the vapor and air in
the lower part of the burner, while by providing the tube 43, air is furnished to
the upper part of the cylinder 35, to escape therefiom through the perforations
above the diaphragm 39 and mix with the vapor By providing the disk 41 a rush
of too much an into the lower part of the cylinder 35 18 prevented.
We have shown the cylinders 37 provided with handles 53 by which the burner
may be turned and adjusted on the cups 29
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. In a vapor buine, the combination of a burner, an elevated supply tank,
and a pipe extending vertically from near the tank to a point near the burner,
said pipe being made sufficiently large to permit the oil to drop therethrough
without coming in contact therewith, substantially as set forth
2. In a vapor burner, the combination of a burner, having a vaporizing cup
with a section of a supply pipe secured thereto, an elevated tank provided with a
nipple and valves, and a feed pipe into which said nipple delivers the oil, said
feed pipe being made sufficiently large to allow the oil to drop therethrough with-
out coming in contact therewith, and said feed pipe communicating with the
section of pipe that is connected to the vaporizing cup through means of a pipe
of smaller diameter, substantially as set forth.
3. In a vapor burner, the combination of a base, constructed to permit the
passage of au, a vaporizing cup located on the base, inner and outer perforated
cylinders arranged over the vaporizing cup, an outer imperforate cylinder sur-
rounding the perforated cylinders, an imperforate diaphragm located within said
inner perforated cylinder, and a pipe extending through the base of the burner
to a point above said diaphragm, substantially as set forth
4. In a vapor burner, the combination of a base constructed to permit the pas-
Bage of air, a vaporizing cup located on the base, inner and outer perforated
cylinders arranged over the vaporizing cup, an outer imperforate cylinder sur-
rounding the perforated cylinders, an imperforate and a perforated diaphragm
located within said inner perforated cylinders, a disk located beneath said pei-
forated diaphragm, and a pipe extending through the base of the burner to a
point above said imperforate diaphragm, substantially as set forth.
5 In a vapor burner, the combination of a base constructed to permit the pas-
sage of air, a vaporizing cup located on the base, inner and outer perforated cylin-
ders arranged over the vaporizing cup, an imperforate cylinder surrounding the
perforated cylinders, a pipe extending through the base of the buiner into said
inner perforated cylinders, means for connecting said cylinders and pipe together,
an arm engaging the lower end of said pipe, and a lever for moving said arm to
lift said cylinders from the vaporizing cup, substantially as set forth
