Improvements in Incandescent Vapour Lamps.
We, WATSON BIRDSALL RULON, General Engineer, and JOSEPH SWIFT KEEN,
Junior, General Engineer, both of No. 112, North Broad Street, Philadelphia,
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:-
Our invention relates to an incandescent lamp for burning hydro-carbon oil
or fluid embodying a vaporizing chamber, of novel construction, containing an
inner apertured tube, a perforated diaphragm at the ends thereof, whereby the
hydrocarbon is divided into a plurality of streams, and thereby effectively dis-
integrated and heated, a super-heater, gas or vapour generators, an oil or fluid
supply pipe leading to said chamber and a gas or vapour-conveying pipe leading
from said super-heater to the gas or vapor flue of the burner, said parts being
continuous, causing effective vaporization and means for preventing or relieving
the clogging of the discharge opening of the vapor-conveying pipe in said flue,
producing a superior lamp of compact, simple and inexpensive construction, as
will be hereinafter described.
In the accompanying drawing:
Figure 1 represents a vertical section of lamp embodying our invention, show-
ing also in dotted lines what is known as a mantle employed in lamps, of the
class.
Figure 2 represents a vertical section of a portion on line - Figure 1.
Similar letters of reference indicate corresponding parts in the figures.
Referring to the drawings:-
A designates a gas or vapor flue at the top of which is the burner B of the
gauze or other suitable material.
C designates the vaporizing tube or chamber which passes through said flue
and burner and projects above the latter and has connected with its lower end the
pipe 1 which is adapted to communicate with a place of supply of oil or hydro-
carbon fluid and is provided with a regulating cock E for evident purposes.
Connected with the upper end of said tube C is the super-heater or super-heating
pipe F which extends downwardly therefrom by the side of the same and is con-
tinued as at F1, the lower end of the extension being provided with a lateral
branch G which enters the flue A and is in communication with the same by
means of the pin-hole H in said branch, the adjacent end of the branch being
closed.
The pipe F passes through the burner B and has a portion inside of the flue A
and another portion outside of the same, the pipe D being also partly inside and
outside of said flue.
Within the vaporizing tube C is the pipe J of somewhat smaller diameter and
having ports K in the side thereof.
The ends of the pipe J are closed by the screws or plugs L' and are retained in
the tube C by means of the pieces L of gauze or other perforated material which

page_text: are secured to the ends of said pipe J by said screws or plugs L' and are likewise
attached to the tube C, said pieces permitting the passage of oil and vapor there-
through, as will be hereinafter more fully explained.
For primarily heating the vaporizing chamber, the lamp M, preferably for
alcohol, is employed, the same being located adjacent to the burner B, so that
the heat of its flame is communicated to said chamber, said lamp being equipped
with a wick, an asbestos pad and a filling tube.
Connected with the lower end of the flue is the cup or vessel N, which is
adapted to receive the carbonization that may be formed within said flue and drop
therefrom.
Within the flue, at the lower end of the same, is the pin P which is located
above the pin hole H and adapted to have its point enter therein, said pin being
connected with the sliding plates Q which are freely fitted to opposite sides of the
wall of the flue and carry the shank R of said pin, said shank freely occupying
the slot S in said wall, so that said pin may be raised and lowered while the slot
remains closed, provision thus being made for pricking the pin-holes should the
same be clogged or otherwise obstructed.
It will be seen that as oil or fluid is supplied through the pipe D of the vapor-
izer C and passes through the lower gauze L, some of the fluid enters the in-
terior pipe J, through the lower port K and traversing said pipe until it reaches
the upper port when it again returns into the vaporizer, the oil or fluid thus being
divided and passing upwardly in different streams and being subjected to the heat
of the vaporizer proper and that of the pipe J within the same, it then passes
through the upper gauze L to the top of the vaporizer, thus converting the oil or
fluid into gas or vapor which is directed into the super-heater F, whereby the gas
or vapor is super-heated in which condition it is directed into the flue A and
passed to the burner where it is ignited, the flame being directed against the
vaporizer and superheating and conveyor pipe, while also heating the gas flue
and the pipes in the latter.
In order to adjust the mantle, the crane or arm T which is attached to said
mantle as at U is made movable in vertical direction and freely guided in the
frame of the lamp, its lower portion being provided with the rack bar V with
which meshes the pinion W, whose shaft mounted on said frame carries the hand
or operating wheel X, whereby the arm and consequently the mantle may be
conveniently raised and lowered.
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:-
1st. In a lamp, the combination of a vaporizing chamber with an apertured
pipe located within the latter, and in communication therewith at its opposite
ends.
2nd. In a lamp the combination of a vaporizing chamber, an apertured pipe
within said chamber, and a perforated diaphragm located at or near the end
of said pipe.
3rd. In a lamp, a vaporizing chamber, in combination with a pipe therein pro-
vided with ports forming communication between said parts and perforated
pieces connecting the ends of said pipe with the interior of said chamber.
4th. In a lamp, the combination of a flue, a burner, a vaporizing chamber
extending above the same, an apertured pipe contained within said chamber and
having perforated diaphragms at its ends, a super-heater located in proximity
to said chamber and communicating therewith, a branch extending laterally from
said superheater into said flue and provided with an outlet port and means for
pricking said port.
5th. A vapor flue, a vaporizer, a pipe extending from said vaporizer and a
branch continuing laterally from said pipe into the flue and provided with a dis-
charge opening in said flue, in combination with a pin in said flue adapted to

page_text: enter said opening and a carrier for said pin adapted to move the latter to and
from said opening.
6th. In a lamp, a vapor flue and a vaporizer leading to a superheater in com-
munication therewith, and a sliding pin for pricking the discharge opening of
the conveying pipe within said flue.
7th. A vapor flue and a vapor-conveying pipe entering said flue and provided
with an outlet therein, a pin in said flue adapted to enter said outlet and a plate
carrying said pin adapted to move said pin to and from said outlet.
8th. In a lamp, a vapor flue and a cap at the lower end of said flue adapted to
receive the carbonization of the latter.
9th. In a lamp, the combination of a flue, a vaporizing chamber, a pipe having
closed ends located within the latter and communicating with said chamber,
perforated diaphragms located near the ends of said pipe, a superheater commu-
nicating with said chamber, a pipe leading from said superheater to a branch
entering said flue, an outlet port in said branch and means for pricking said port.
10th. The combination of a flue, a vaporizing chamber, an apertured pipe
located therein and communicating therewith, a superheater leading from said
chamber to said flue and a cap at the lower end of said flue adapted to receive
the carbonization of the latter.
11th. In a lamp of the character named, a vaporizing chamber, in combination
with a pipe therein having closed ends and provided with ports and perforated
diaphragms common to the ends of said pipe and the interior of said chamber,
whereby the hydro-carbon is divided up into a plurality of streams in its passage
through said chamber.
12th. In a lamp of the character stated, a support for the mantle and means
for vertically-adjusting the same.
